Aspirin loading and coronary no-reflow after percutaneous coronary intervention in patients with acute myocardial infarction. Eur J Clin Invest 2024; 54:e14173. [PMID: 38264959 DOI: 10.1111/eci.14173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 01/15/2024] [Accepted: 01/15/2024] [Indexed: 01/25/2024]
Abstract
BACKGROUND The association of aspirin loading with the risk of coronary no-reflow (CNR) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has not been investigated. We assessed the association of aspirin loading before PCI with CNR in patients with AMI. MATERIALS AND METHODS This study included 3100 patients with AMI undergoing PCI. Of them, 2812 patients received aspirin loading (a single oral [or chewed] or intravenous dose of 150-300 mg) and 288 patients did not receive aspirin loading before PCI. The primary endpoint was CNR, defined as Thrombolysis in Myocardial Infarction blood flow grade of <3 after the PCI. RESULTS CNR occurred in 130 patients: 127 patients in the group with aspirin loading and 3 patients in the group without aspirin loading before PCI (4.5% vs. 1.0%; odds ratio [OR] = 4.50, 95% confidence interval, [1.42-14.21], p = 0.005). After adjustment, the association between aspirin loading and CNR was significant (adjusted OR = 4.49 [1.56-12.92]; p < 0.001). There was no aspirin loading-by-P2Y12 inhibitor (ticagrelor or prasugrel) interaction (pint = 0.465) or aspirin loading-by-chronic aspirin therapy on admission (pint = 0.977) interaction with respect to the occurrence of CNR after PCI. Chronic low-dose aspirin therapy on admission was not independently associated with higher risk of CNR after PCI (adjusted OR = 1.06 [0.65-1.72]; p = 0.824). CONCLUSION In patients with AMI undergoing PCI, aspirin loading before the PCI procedure at the guideline-recommended doses was associated with higher odds of developing CNR. However, due to the limited number of events, the findings should be considered as hypothesis generating.

Incidence and pattern of urgent revascularization in acute coronary syndromes treated with ticagrelor or prasugrel. Clin Res Cardiol 2024:10.1007/s00392-024-02454-x. [PMID: 38740722 DOI: 10.1007/s00392-024-02454-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 04/25/2024] [Indexed: 05/16/2024]
Abstract
BACKGROUND The ISAR-REACT 5 trial compared the efficacy and safety of ticagrelor and prasugrel in patients with ACS managed invasively. The present study sought to investigate the impact of ticagrelor and prasugrel on the incidence and pattern of urgent revascularization in acute coronary syndromes (ACS) patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS This post-hoc analysis of the ISAR-REACT 5 trial included all ACS patients who underwent PCI. The primary endpoint for this analysis was the incidence of urgent revascularization at 12-month follow-up. Secondary outcome was the pattern of urgent revascularization procedures (namely, urgent target vessel/non-target vessel revascularization - TVR/NTVR). Among 3,377 ACS patients who underwent PCI, 1,676 were assigned to ticagrelor and 1,701 to prasugrel before PCI. After 12 months, the incidence of urgent revascularization was higher among patients assigned to ticagrelor as compared to prasugrel (6.8% vs. 5.2%; hazard ratio [HR] = 1.32, 95% confidence interval [CI] 1.00-1.75; p = 0.051), mostly attributable to significantly more urgent NTVR in the ticagrelor group (3.8% vs. 2.4%; HR = 1.62 [1.09-2.41]; p = 0.017). The risk of urgent TVR did not differ between treatment groups (3.3% vs. 3.0%; HR = 1.13 [0.77-1.65]; p = 0.546). CONCLUSIONS In ACS patients treated with PCI, the cumulative rate of urgent revascularizations after 12 months is higher with ticagrelor compared to prasugrel, due to a significant increase in urgent revascularizations involving remote coronary vessels.

A Ten-Year Follow-Up Study of the Association Between Uric Acid and Adverse Cardiovascular Events in Patients With Coronary Artery Disease. Am J Cardiol 2024; 216:19-26. [PMID: 38336081 DOI: 10.1016/j.amjcard.2024.01.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/09/2024] [Accepted: 01/19/2024] [Indexed: 02/12/2024]
Abstract
The association between uric acid (UA) and long-term mortality in patients with coronary artery disease is poorly investigated. We assessed the association between UA and 10-year mortality after percutaneous coronary intervention (PCI) in 3,998 patients who underwent PCI. Patients were categorized in groups according to UA tertiles: tertile 1 (UA <5.80 mg/100 ml, n = 1,347), tertile 2 (UA 5.80 to 7.04 mg/100 ml, n = 1,340), and tertile 3 (UA >7.94 mg/100 ml, n = 1,311). The primary outcome was 10-year all-cause mortality. All-cause deaths occurred in 1,200 patients: 320 deaths (26.5%) in patients with UA in the first tertile, 325 deaths (26.9%) in patients with UA in the second tertile, and 555 deaths (46.0%) in patients with UA in the third tertile (adjusted hazard ratio 1.22, 95% confidence interval 1.17 to 1.27, p <0.001) for 1 mg/100 ml increment in UA level. Cardiac deaths occurred in 748 patients: 194 deaths (16.5%) in patients with UA in the first tertile, 202 deaths (17.0%) in patients with UA in the second tertile, and 352 deaths (29.7%) in patients with UA in the third tertile (adjusted hazard ratio 1.24 [1.17 to 1.32], p <0.001) for 1 mg/100 ml increment in the UA level. The 10-year rates of target lesion revascularization, target vessel revascularization, or nontarget vessel revascularization did not differ significantly according to the UA level. In conclusion, in patients with coronary artery disease treated with PCI, increased UA level was associated with higher 10-year mortality. Increased UA level was not associated with the progression of atherosclerosis in nontreated coronary vessels or progression of intimal hyperplasia in stented lesions requiring intervention.

Recurrent Revascularization at 10 Years After Percutaneous Treatment of Drug-Eluting Stent Restenosis. JACC Cardiovasc Interv 2024; 17:1-13. [PMID: 37902151 DOI: 10.1016/j.jcin.2023.10.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/03/2023] [Accepted: 10/13/2023] [Indexed: 10/31/2023]
Abstract
BACKGROUND Treatment of patients with recurrence of in-stent restenosis (ISR) remains particularly challenging, with data and guideline recommendations for repeat percutaneous coronary intervention being scant. OBJECTIVES The aim of this study was to investigate the long-term incidence of recurrent revascularization events after percutaneous treatment of drug-eluting stent (DES) ISR. METHODS In this post hoc analysis, 402 patients (500 lesions) assigned to plain balloon (PB), drug-coated balloon (DCB), or DES treatment in the randomized ISAR-DESIRE 3 (Efficacy Study of Paclitaxel-Eluting Balloon, -Stent vs. Plain Angioplasty for Drug-Eluting Stent Restenosis) trial were followed up over a median of 10.3 years. The primary endpoint was total repeat target lesion revascularization (R-TLR) including all, first and recurrent, events. RESULTS At the end of follow-up, first R-TLR was required in 204 lesions, 82 in the PB group, 70 in the DCB group, and 52 in the DES group. The total number of R-TLRs was 373: 162 in the PB group, 124 in the DCB group, and 87 in the DES group. During the first year of follow-up, the risk for total R-TLR was reduced by DCB (HR: 0.36; 95% CI: 0.24-0.54) and DES (HR: 0.23; 95% CI: 0.14-0.38) treatment compared with PB treatment. After 1 year, the risk for total R-TLR was nonsignificantly reduced by DCB treatment (HR: 0.77; 95% CI: 0.51-1.16) and significantly reduced by DES treatment (HR: 0.61; 95% CI: 0.39-0.95) compared with PB treatment. Risk in the DCB and DES groups was similar during (HR: 1.54; 95% CI: 0.89-2.69) and after (HR: 1.26; 95% CI: 0.82-1.92) 1 year. CONCLUSIONS The total number of R-TLRs over 10 years after treatment of patients with DES ISR was high. DCBs and particularly DES were able to reduce the need for both first and recurrent revascularization compared with PB treatment.

In-hospital Outcomes of Rotational Atherectomy in ST-Elevation Myocardial Infarction: Results From the Multicentre ROTA-STEMI Network. Can J Cardiol 2023:S0828-282X(23)02034-2. [PMID: 38147962 DOI: 10.1016/j.cjca.2023.12.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 12/16/2023] [Accepted: 12/18/2023] [Indexed: 12/28/2023] Open
Abstract
BACKGROUND Although the use of rotational atherectomy (RA) is off-label in the setting of ST-elevation myocardial infarction (STEMI), it can be the only option in severely calcified culprit lesions to achieve procedural success. We sought to investigate the safety and feasibility of RA during primary percutaneous coronary intervention (PPCI). METHODS This was a retrospective observational study of patients who underwent RA during PPCI from 12 European centres. The main outcomes were procedural success (defined as successful stent implantation with final thrombolysis in myocardial infarction [TIMI] flow 3 and residual stenosis < 30%) and in-hospital mortality. A comparison of patients presenting with and without shock was performed. RESULTS In 104 patients with RA during STEMI, the mean age was 72.8 ± 9.1 years, and 35% presented with cardiogenic shock. Bailout RA was performed in 76.9% of cases. Mean burr size was 1.42 ± 0.21 mm. Procedural success was achieved in 86.5% of cases, with no difference between shocked and nonshocked patients (94.4% vs 82.4%; P = 0.13). In-hospital stent thrombosis occurred in 0.96%, perforation in 1.9% and burr entrapment in 2.9% of cases. In spite of equally high procedural success, in-hospital mortality was higher in shocked (50%) compared with nonshocked patients (1.5%; P < 0.0001). CONCLUSIONS Patients presenting with STEMI requiring RA, represent a high-risk population, frequently presenting with cardiogenic shock. In this analysis of selected patients, RA was performed as a bailout strategy in the majority, and, as such, RA seems to be feasible with a high procedural success rate. In the absence of cardiogenic shock, RA-facilitated PCI seems to be associated with low in-hospital mortality.

Comparison of long-term outcome in patients with in-stent restenosis treated with intravascular lithotripsy or with modified balloon angioplasty. Clin Res Cardiol 2023:10.1007/s00392-023-02357-3. [PMID: 38112745 DOI: 10.1007/s00392-023-02357-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 12/04/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND Modified balloon angioplasty (MB) using a cutting-/scoring balloon or intravascular lithotripsy (IVL) is used in patients with in-stent restenosis (ISR). However, IVL is an off-label use in this setting. The aim of this subgroup analysis of an all-comers registry was to compare IVL to MB angioplasty in patients with ISR. METHODS The subgroup (n = 117) included all patients with an ISR treated by MB or IVL between 2019 and 2021. Primary endpoint was strategy success (< 20% residual stenosis). The secondary endpoint was cardiac death, acute myocardial infarction (AMI) and target lesion failure/revascularization (TVR). Quantitative coronary angiography was performed in all patients. RESULTS A total of n = 36 patients were treated by IVL and n = 81 patients by MB. No significant differences in baseline characteristics were observed between the groups. The primary endpoint was reached in 99 patients (84.6%). Patients in the IVL group had less residual stenosis (2.8% vs. 21.0%; p = 0.012). Multivariate regression analysis revealed that IVL had a significant positive effect on reaching the primary end point (Estimate 2.857; standard error (SE) 1.166; p = 0.014). During the follow-up period (450 days) there were no significant differences in rates of cardiac death (IVL n = 2 (1.7%) vs. MB n = 3 (2.6%); p = 0.643), AMI (IVL n = 2 (1.7%) vs. MB n = 4 (3.4%); p = 0.999) and TVR (IVL n = 5 (4.3%) vs. MB n = 14 (12%); p = 0.851). CONCLUSION IVL results in a significantly lower rate of residual stenosis than MB in patients with ISR. During the long-term follow-up, no differences in rates of cardiac death, AMI or TVR were observed.

Coronary no-reflow and adverse events in patients with acute myocardial infarction after percutaneous coronary intervention with current drug-eluting stents and third-generation P2Y 12 inhibitors. Clin Res Cardiol 2023:10.1007/s00392-023-02340-y. [PMID: 37962571 DOI: 10.1007/s00392-023-02340-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 11/06/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND The frequency and prognostic value of coronary no-reflow (CNR) was investigated in studies that have used an outdated reperfusion therapy in terms of stent technology and antithrombotic drugs. We assessed the association of CNR with adverse outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) and newer antithrombotic drugs, ticagrelor or prasugrel. METHODS This study included 3100 patients with AMI who underwent PCI with current DES and third-generation P2Y12 inhibitors. CNR was defined as Thrombolysis in Myocardial Infarction (TIMI) blood flow grade ≤ 2 at the end of PCI. The primary end point was 1-year incidence of net adverse clinical and cerebral events-a composite end point of death of any cause, myocardial infarction, stroke or major bleeding. RESULTS CNR was diagnosed in 130 patients (4.2%). The primary end point occurred in 28 patients in the CNR group and 354 patients in the reflow group (cumulative incidence 23.2% and 12.8%; adjusted hazard ratio = 1.53, 95% confidence interval 1.01-2.33; P = 0.049). The 1-year incidences of death or myocardial infarction (14.6% vs. 7.6%; P = 0.003), myocardial infarction (8.8% vs. 3.9%; P = 0.007) and major bleeding (10.9% vs. 5.6%; P = 0.008) were significantly higher in patients with CNR than patients with reflow. The risk of adverse events in patients with CNR was highest within the first 30 days after PCI. CONCLUSION In patients with AMI undergoing PCI with current DES and third generation P2Y12 receptor inhibitors, CNR was associated with a higher risk of adverse outcomes at 1 year.

Modified balloons to prepare severely calcified coronary lesions before stent implantation: a systematic review and meta-analysis of randomized trials. Clin Res Cardiol 2023:10.1007/s00392-023-02324-y. [PMID: 37930402 DOI: 10.1007/s00392-023-02324-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Accepted: 10/12/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND The performance of modified balloons (namely cutting or scoring balloons) to prepare severely calcified lesions in patients undergoing percutaneous coronary intervention (PCI) remains controversial. We investigated the clinical and imaging outcomes of patients undergoing PCI assigned to modified balloon therapy to prepare severely calcified coronary lesions before stent implantation. METHODS In this meta-analysis, we aggregated the study-level data from trials enrolling invasively treated patients who were randomly assigned to modified balloon or control therapy to prepare severely calcified lesions before stenting. The primary outcome was major adverse cardiac events (MACE), including death, myocardial infarction (MI), and repeat revascularization. The secondary outcomes included the individual components of the primary outcome, coronary perforation and final minimal stent area (MSA) as measured by intracoronary imaging. RESULTS A total of 648 participants in six trials were allocated to modified balloon therapy (n = 335) or control therapy (semi-compliant, non-compliant, or super high-pressure balloon, n = 313). The median follow-up was 11 months. Overall, MACE occurred in 8.96% of patients assigned to a modified balloon and 12.78% of patients assigned to control therapy [risk ratio = 0.70, 95% confidence interval (CI) 0.35-1.39; P = 0.24]. There was a significant treatment effect-by-modified balloon type interaction for the outcome MACE in patients assigned to cutting balloon compared with control therapy [RR = 0.40 (0.28-0.56), P for interaction (Pint) < 0.001]. Patients treated with a modified balloon compared with control therapy showed neither a significant difference for the other clinical outcomes nor for final MSA [standardized mean difference = 0.67 (- 0.71, 2.06); P = 0.26]. CONCLUSIONS In patients treated with PCI for severely calcific coronary artery disease a strategy of lesion preparation with a modified balloon before stenting does not improve clinical or imaging outcomes compared with control therapy. The different performance of cutting and scoring balloons warrants further investigation.

Rationale and design of the PARTHENOPE trial: A two-by-two factorial comparison of polymer-free vs biodegradable-polymer drug-eluting stents and personalized vs standard duration of dual antiplatelet therapy in all-comers undergoing PCI. Am Heart J 2023; 265:153-160. [PMID: 37572785 DOI: 10.1016/j.ahj.2023.08.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 07/29/2023] [Accepted: 08/02/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Over the past few decades, percutaneous coronary intervention (PCI) has undergone significant advancements as a result of the combination of device-based and drug-based therapies. These iterations have led to the development of polymer-free drug-eluting stents. However, there is a scarcity of data regarding their clinical performance. Furthermore, while various risk scores have been proposed to determine the optimal duration of dual antiplatelet therapy (DAPT), none of them have undergone prospective validation within the context of randomized trials. DESIGN The PARTHENOPE trial is a phase IV, prospective, randomized, multicenter, investigator-initiated, assessor-blind study being conducted at 14 centers in Italy (NCT04135989). It includes 2,107 all-comers patients with minimal exclusion criteria, randomly assigned in a 2-by-2 design to receive either the Cre8 amphilimus-eluting stent or the SYNERGY everolimus-eluting stent, along with either a personalized or standard duration of DAPT. Personalized DAPT duration is determined by the DAPT score, which accounts for both bleeding and ischemic risks. Patients with a DAPT score <2 (indicating higher bleeding than ischemic risk) receive DAPT for 3 or 6 months for chronic or acute coronary syndrome, respectively, while patients with a DAPT score ≥2 (indicating higher ischemic than bleeding risk) receive DAPT for 24 months. Patients in the standard DAPT group receive DAPT for 12 months. The trial aims to establish the noninferiority between stents with respect to a device-oriented composite end point of cardiovascular death, target-vessel myocardial infarction, or clinically-driven target-lesion revascularization at 12 months after PCI. Additionally, the trial aims to demonstrate the superiority of personalized DAPT compared to a standard approach with respect to a net clinical composite of all-cause death, any myocardial infarction, stroke, urgent target-vessel revascularization, or type 2 to 5 bleeding according to the Bleeding Academic Research Consortium criteria at 24-months after PCI. SUMMARY The PARTHENOPE trial is the largest randomized trial investigating the efficacy and safety of a polymer-free DES with a reservoir technology for drug-release and the first trial evaluating a personalized duration of DAPT based on the DAPT score. The study results will provide novel insights into the optimizing the use of drug-eluting stents and DAPT in patients undergoing PCI.

Abstract
Background: Finding the appropriate endovascular revascularization strategy for patients with peripheral artery disease and a popliteal artery lesion remains particulary challenging. Data regarding predictors for a beneficial outcome are scarce. Patients and methods: All endovascular procedures of popliteal artery lesions (n=227) performed in 197 patients between February 2009 and May 2018 at our institution were retrospectively analyzed. Hemodynamically relevant restenosis represented the primary endpoint. Results: The overall technical success rate was 98% and yielded 99% for stenoses (n=145) and 97% for occlusions (n=82). In a median follow-up of 10 months, the overall rate of restenosis was 23%. After 1 and 2 years, the primary patency rates were 76% and 55% and the secondary patency rate was 100%, respectively. The estimated probability of restenosis was significantly higher in stented lesions (stent vs. no stent; 36.0% vs. 19.1%; p=0.030). Multivariate analysis identified stent implantation (hazard ratio: 2.4; overall P=0.010) and diabetes (hazard ratio 2.0; P=0.023) as significant predictors for the development of restenosis. Conclusions: Endovascular therapy for popliteal artery disease was associated with high technical success rates and accompanied with a promising mid-term outcome, particularly in lesions treated with balloon angioplasty alone.

Very long-term outlook of acute coronary syndromes after percutaneous coronary intervention with implantation of polymer-free versus durable-polymer new-generation drug-eluting stents. Minerva Med 2023; 114:590-600.

Abstract
BACKGROUND Detailed long-term follow-up data on patients with acute coronary syndromes (ACS) in general, and those with ST-elevation myocardial infarction (STEMI) in particular, are limited. We aimed to appraise the long-term outlook of patients undergoing percutaneous coronary intervention (PCI) with state-of-the-art coronary stents for STEMI, other types of ACS and stable coronary artery disease (CAD), and also explore the potential beneficial impact of new-generation polymer-free drug-eluting stents (DES) in this setting. METHODS Baseline, procedural and very long-term outcome data on patients undergoing PCI and randomized to implantation of new-generation polymer-free vs. durable polymer DES were systematically collected, explicitly distinguishing subjects with admission diagnosis of STEMI, non-ST-elevation ACS (NSTEACS), and stable CAD. Outcomes of interest included death, myocardial infarction, revascularization (i.e. patient-oriented composite endpoints [POCE]), major adverse cardiac events (MACE), and device-oriented composite endpoints (DOCE). RESULTS A total of 3002 patients were included, 1770 (59.0%) with stable CAD, 921 (30.7%) with NSTEACS, and 311 (10.4%) with STEMI. At long-term follow-up (7.5±3.1 years), all clinical events were significantly more common in the NSTEACS group and, to a lesser extent, in the stable CAD group (e.g. POCE occurred in, respectively, 637 [44.7%] vs. 964 [37.9%] vs. 133 [31.5%], P<0.001). While these differences were largely attributable to adverse coexisting features in patients with NSTEACS (e.g. advanced age, insulin-dependent diabetes, and extent of CAD), the unfavorable outlook of patients presenting with NSTEACS persisted even after multivariable adjustment including several prognostically relevant factors (hazard ratio [HR] of NSTEACS vs. stable CAD 1.19 [95% confidence interval 1.03-1.38], P=0.016). Notably, even after encompassing all prognostically impactful features, no difference between polymer-free and permanent polymer drug-eluting stents appeared (HR=0.96 [0.84-1.10], P=0.560). CONCLUSIONS Unstable coronary artery disease, especially when presenting without ST-elevation, represents an informative marker of adverse long-term prognosis in current state-of-the-art invasive cardiology practice. Even considering admission diagnosis, and despite of using no polymer, polymer-free DES showed similar results with regards to safety and efficacy when compared with DES with permanent polymer.

BACKGROUND Only few data is available for long-term outcomes of patients being treated for in-stent restenosis (ISR) in saphenous vein grafts (SVG). AIMS Thus, the aim of this observational, retrospective study was to close this lack of evidence. METHODS Between January 2007 and February 2021 a total of 163 patients with 186 ISR lesions located in SVG were treated at two large-volume centers in Munich, Germany. Endpoints of interest were all-cause mortality, target lesion revascularization (TLR) and target vessel myocardial infarction (TVMI). Furthermore, recurrent ISR were assessed. Outcomes are presented as Kaplan-Meier event rates. RESULTS Mean age was 72.6 ± 8.6 years, 90.8% were male, 36.8% were diabetics and 42.3% presented an acute coronary syndrome. ISR were treated with DES in 64.0% and with balloon angioplasty (BA) in 36.0%. After 10 years, the rates for all-cause mortality, TVMI and TLR were 58.2%, 15.4%, and 22.6%, respectively. No statistically relevant differences were found between the types of treatment (DES or BA) regarding all-cause mortality (55.7% vs. 63.2%, p = 0.181), TVMI (13.8% vs. 18.6%, p = 0.215) and TLR (21.8% vs. 25.0%, p = 0.764). Median time between first and recurrent ISR was 270.8 days. Recurrent ISR were treated with DES in a comparable proportion as during first ISR (p = 0.075). Independent predictor of TLR is patient age (p = 0.034). The median follow-up duration was 5.1 years (75% CI 2.8; 8.5). CONCLUSIONS Clinical event rates after intervention of ISR located in SVG are high without statistically relevant differences regarding the type of treatment. However, further studies are needed.

Frequency of subclavian artery stenosis in patients with mammarian artery coronary bypass and suspected coronary artery disease progression. Clin Res Cardiol 2023; 112:1204-1211. [PMID: 36239814 PMCID: PMC10449982 DOI: 10.1007/s00392-022-02113-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 10/04/2022] [Indexed: 12/24/2022]
Abstract
We retrospectively analyzed patient records of all patients with a history of internal mammarian artery (IMA) coronary bypass undergoing coronary angiography at two cardiovascular centers between January 1st 1999 and December 31st 2019. A total of 11,929 coronary angiographies with or without percutaneous coronary intervention were carried out in 3921 patients. Our analysis revealed 82 (2%) patients with documented subclavian artery stenosis. Of these, 8 (10%) patients were classified as having mild, 18 (22%) moderate, and 56 (68%) severe subclavian artery stenosis. In 7 (9%) patients with subclavian artery stenosis, angiography revealed occlusion of the IMA graft. 26 (32%) patients with severe subclavian artery stenosis underwent endovascular or surgical revasculararization of the subclavian artery. In this retrospective multicenter study, subclavian artery stenosis was a relevant finding in patients with an internal mammarian artery coronary bypass graft undergoing coronary angiography. The development of dedicated algorithms for screening and ischemia evaluation in affected individuals may improve treatment of this potentially underdiagnosed and undertreated condition.

Clinical Safety and Efficacy of New-Generation Single-Layer Polytetrafluorethylene Covered Coronary Stents. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 52:30-36. [PMID: 36822974 DOI: 10.1016/j.carrev.2023.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 01/27/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023]
Abstract
BACKGROUND Early-generation "sandwich-design" polytetrafluorethylene (PTFE) covered coronary stents (CS) are associated with a high frequency of adverse events. New-generation single layer PTFE-CS offers the potential to enhanced procedural efficacy and improves clinical safety. Data from a dedicated study, concerning outcomes after treatment with single-layer PTFE-CS in patients undergoing percutaneous coronary intervention are scant. METHODS This is a retrospective multicenter registry including 30 patients undergoing implantation of 39 single-layer PTFE-CS (BeGraft-coronary Stent Graft System, Bentley InnoMed GmbH, Hechingen, Germany) in native coronary arteries or saphenous bypass grafts, in 3 centers in Europe, between May 2013 and May 2019. Endpoints of interest were procedural success (placement of covered stent), binary-angiographic restenosis (BAR), percent diameter stenosis (% DS) and late-lumen loss at 6-8 months follow-up angiography, rates of target lesion revascularization (TLR), myocardial infarction (MI), stent thrombosis (ST) and mortality at 12 months. RESULTS 28 patients underwent implantation of 37 CS due to coronary artery perforation 2 patients due to coronary artery aneurysm. Technical success was achieved in all patients (100 %). More than one stent was implanted in 7 patients (25 %) all in the perforation group. Follow-up angiography was available in 23 patients (77 %) showing favorable results: BAR = 21.8 %, %DS = 30.3 ± 27.5; LLL = 0.16 ± 0.81 mm. At 12 months all patients were alive, rates of TLR were low (3 patients, 10.0 %), there was one case of late stent thrombosis (3.3 %) and one MI (3.3 %). CONCLUSIONS In this dedicated study, implantation of a new single layer PTFE-CS for the treatment of native coronary arteries or saphenous vein grafts after perforation or due to aneurysm showed high technical success rates and favorable angiographic and clinical efficacy. Clinical safety outcomes are encouraging, but larger prospective studies are needed to determine long-term safety of this device.

Comparison of long-term outcome in patients with calcified stenosis treated with intravascular lithotripsy or with modified balloon angioplasty: a propensity score-adjusted study. Front Cardiovasc Med 2023; 10:1185422. [PMID: 37255702 PMCID: PMC10225498 DOI: 10.3389/fcvm.2023.1185422] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 04/26/2023] [Indexed: 06/01/2023] Open
Abstract
Background The aim of this two-center, all-comers registry was to compare the effectiveness and safety of intravascular lithotripsy (IVL) to that of modified balloon angioplasty (MB). MB angioplasty using a cutting or scoring balloon is commonly used in patients with calcified coronary arteries. IVL is a new technology for lesion preparation. This is the first study to compare MB with IVL. Methods The cohort included all patients treated by MB angioplasty or IVL between 2019 and 2021. The primary endpoint was strategy success (<20% residual stenosis). The secondary endpoint was long-term safety outcomes [cardiac death, acute myocardial infarction (AMI), target lesion failure/revascularization (TVR)]. Quantitative coronary angiography (QCA) was performed in all patients. Primary and secondary endpoints were compared using inverse probability of treatment weighting (IPTW) for treatment effect estimation. Results A total of n = 86 patients were treated by IVL and n = 92 patients by MB angioplasty. The primary endpoint was reached in 152 patients (85.4%). Patients in the IVL group had less residual stenosis (5.8% vs. 22.8%; p = 0.001) in QCA. Weighted multivariable regression analysis revealed that IVL had a significant positive effect on reaching the primary endpoint of strategy success [odds ratio (OR) 24.58; 95% confidence interval (95% CI) 7.40-101.86; p = 0.001]. In addition, severe calcification was shown to result in a lower probability of achieving the primary endpoint (OR 0.08; 95% CI 0.02-0.24; p = 0.001). During the follow-up period (450 days) there was no difference in cardiovascular mortality rate [IVL (n = 5) 2.8% vs. MB (n = 3) 1.7%; p = 0.129]. Patients with unstable angina at the time of the index procedure had the highest probability of cardiovascular death [hazard ratio (HR) 7.136; 95% CI 1.248-40.802; p = 0.027]. No differences were found in long-term rates of AMI (IVL 1.7% vs. MB 2.8%; p = 0.399; IVL HR 2.73; 95% CI 0.4-17.0; p = 0.281) or TVR (IVL 5.6% vs. MB 9%; p = 0.186; IVL HR 0.78; 95% CI 0.277-2.166; p = 0.626). Conclusion IVL leads to a significantly better angiographic intervention outcome compared to MB angioplasty in our cohort. During long-term follow-up, no differences in cardiovascular mortality, rate of acute myocardial infarction, or target lesion failure/revascularization were observed.

Association of De Ritis Ratio with Prognosis in Patients with Coronary Artery Disease and Aminotransferase Activity within and outside the Healthy Values of Reference Range. J Clin Med 2023; 12:jcm12093174. [PMID: 37176615 PMCID: PMC10178981 DOI: 10.3390/jcm12093174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/24/2023] [Accepted: 04/25/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND The aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (De Ritis ratio), obtained from AST and ALT activities in the healthy range, has not been studied in association with mortality. METHODS This study included 3392 patients with stable coronary heart disease and aminotransferase activity in the reference range. Patients are categorized into two groups: a group with AST and ALT activity in the healthy range (n = 1697), and a group with AST and/or ALT activity outside the healthy range but in the reference range (n = 1695). The primary endpoint was all-cause mortality at three years. RESULTS The De Ritis ratio (median 5th-95th percentile] was 0.94 [0.61-1.41] in patients with AST and ALT in the healthy range and 0.93 [0.45-1.96] in patients with AST and/or ALT outside the healthy range (p = 0.700). At three years, there were 86 deaths in patients with AST and ALT in the healthy range: 27 deaths (3.9%) in patients with a De Ritis ratio ≤median, and 59 deaths (8.2%) in patients with the De Ritis ratio >median (adjusted hazard ratio [HR] = 1.16, 95% confidence interval [CI] 0.94 to 1.42; p = 0.159); in patients with AST and/or ALT outside the healthy range, there were 148 deaths: 49 deaths (6.6%) in patients with a De Ritis ratio ≤median, and 99 deaths (14.1%) in patients with De Ritis ratio >median (adjusted HR = 1.27 [1.09-1.48], p = 0.002), with both HRs calculated per unit higher values of the De Ritis ratio. CONCLUSIONS The De Ritis ratio obtained from AST and ALT activity in the healthy range was not independently associated with higher risk of mortality. The De Ritis ratio obtained from aminotransferase activity outside the healthy range (but still in the reference range) was independently associated with the risk of mortality.

Prevalence and patterns of in-stent neoatherosclerosis in lower extremity artery disease. EUROINTERVENTION 2023; 18:1462-1470. [PMID: 36714952 PMCID: PMC10111128 DOI: 10.4244/eij-d-22-00615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 10/12/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND In-stent restenosis (ISR) is responsible for a rapid decline of vessel patency after stenting. To date, little is known about the role of in-stent neoatherosclerosis (NA) in stent failure in lower limb arteries. AIMS This study aimed to determine the prevalence and patterns of in-stent NA in patients with symptomatic ISR of the lower extremity vasculature using intravascular optical coherence tomography (OCT) imaging. METHODS Patients underwent endovascular revascularisation for ISR including angiography and OCT imaging. NA was defined as the presence of at least 1 fibroatheroma or fibrocalcific plaque within the neointima of a stented segment. RESULTS Using OCT, we imaged 24 symptomatic patients with lower extremity artery disease (LEAD), with a total of 30 ISR in the lower limbs, prior to their scheduled endovascular interventions. NA formation was observed in 23 (76.7%) lesions, while all stents with an implant duration >5 years (n=8) showed signs of NA. The time from stent implantation to OCT was significantly increased in lesions with NA (p=0.002). Lesions without NA had a significantly shorter duration from index procedure to OCT than those with ≥50 percent (n=9; p=0.003) or <50 percent (n=14; p=0.015) of frames exhibiting signs of NA. NA was predominantly characterised by fibroatheroma with thick fibrous caps with or without calcification. CONCLUSIONS In-stent NA is frequently identified by OCT imaging after endovascular therapy in lower limb arteries; this increased both in frequency and extent the longer the duration since implantation. Our findings indicate an active atherosclerotic process that may need tailored mitigation strategies.

Machine Learning Identifies New Predictors on Restenosis Risk after Coronary Artery Stenting in 10,004 Patients with Surveillance Angiography. J Clin Med 2023; 12:jcm12082941. [PMID: 37109283 PMCID: PMC10142067 DOI: 10.3390/jcm12082941] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/31/2023] [Accepted: 04/15/2023] [Indexed: 04/29/2023] Open
Abstract
OBJECTIVE Machine learning (ML) approaches have the potential to uncover regular patterns in multi-layered data. Here we applied self-organizing maps (SOMs) to detect such patterns with the aim to better predict in-stent restenosis (ISR) at surveillance angiography 6 to 8 months after percutaneous coronary intervention with stenting. METHODS In prospectively collected data from 10,004 patients receiving percutaneous coronary intervention (PCI) for 15,004 lesions, we applied SOMs to predict ISR angiographically 6-8 months after index procedure. SOM findings were compared with results of conventional uni- and multivariate analyses. The predictive value of both approaches was assessed after random splitting of patients into training and test sets (50:50). RESULTS Conventional multivariate analyses revealed 10, mostly known, predictors for restenosis after coronary stenting: balloon-to-vessel ratio, complex lesion morphology, diabetes mellitus, left main stenting, stent type (bare metal vs. first vs. second generation drug eluting stent), stent length, stenosis severity, vessel size reduction, and prior bypass surgery. The SOM approach identified all these and nine further predictors, including chronic vessel occlusion, lesion length, and prior PCI. Moreover, the SOM-based model performed well in predicting ISR (AUC under ROC: 0.728); however, there was no meaningful advantage in predicting ISR at surveillance angiography in comparison with the conventional multivariable model (0.726, p = 0.3). CONCLUSIONS The agnostic SOM-based approach identified-without clinical knowledge-even more contributors to restenosis risk. In fact, SOMs applied to a large prospectively sampled cohort identified several novel predictors of restenosis after PCI. However, as compared with established covariates, ML technologies did not improve identification of patients at high risk for restenosis after PCI in a clinically relevant fashion.

Derivation and validation of the ISAR score to predict the risk of repeat percutaneous coronary intervention for recurrent drug-eluting stent restenosis. EUROINTERVENTION 2023; 18:e1328-e1338.

Abstract
BACKGROUND The treatment of drug-eluting stent (DES) in-stent restenosis (ISR) is challenging as it has a high risk of recurrence. AIMS The aim of this analysis was to develop and validate a model to predict the risk of repeat percutaneous coronary intervention (PCI) for recurrent DES-ISR. METHODS A retrospective, observational analysis was performed including consecutive patients treated with PCI for DES-ISR at two centres in Germany. Included patients were randomly divided into training and validation cohorts. Two regression analyses identified factors associated with repeat PCI for recurrent DES-ISR up to 1 year. The discriminative ability of the resultant model was then compared to a benchmark ISR classification model using bootstrap resampling. A classification and regression tree analysis and a numerical scoring system (the ISAR score) were used to predict the risk of repeat PCI for recurrent DES-ISR based on the identified predictors. RESULTS We included 1,986 patients in the current analysis, divided randomly into training (1,471 patients, 1,778 lesions) and validation (515 patients, 614 lesions) cohorts. Four factor variables (a non-focal ISR pattern, a time interval to ISR of <6 months, ISR of the left circumflex artery and ISR in a calcified vessel) were associated with repeat PCI for recurrent DES-ISR at 1-year follow-up. On bootstrap resampling analysis, the C-statistic for the model including these four variables was 0.60 (95% confidence interval [CI]: 0.57-0.63), whereas the C-statistic for the benchmark ISR classification model was 0.54 (95% CI: 0.52-0.57), a difference that was statistically significant (delta C-statistic 0.062; 95% CI: 0.035-0.094; p<0.001). The cumulative incidence of repeat PCI for recurrent DES-ISR was over three times higher in DES-ISR lesions with an ISAR score of ≥3 in comparison to lesions with an ISAR score of 0. CONCLUSIONS This study developed and validated a risk prediction model for repeat PCI for recurrent DES-ISR at 1-year follow-up. This model served to generate the ISAR score, a standardised tool that can be used to predict the 1-year risk of repeat PCI for recurrent DES-ISR.

Abstract
BACKGROUND The relative efficacy and safety of ticagrelor and prasugrel based dual antiplatelet therapy strategies according to the platelet count (PC) in patients with acute coronary syndromes (ACS) have not been defined. METHODS This is a posthoc analysis of the ISAR-REACT 5 trial, in which patients presenting with ACS were randomized to treatment with ticagrelor versus prasugrel. Patients were divided into quartiles according to PC. The primary endpoint was incidence of death, myocardial infarction, or stroke, and the safety endpoint was incidence of BARC (Bleeding Academic Research Consortium) type 3 to 5 bleeding at 12 months. RESULTS A total of 3,943 patients with known PC (997 patients in quartile 1 (Q1), 1,003 in quartile 2 (Q2) [205 ± 10.3 × 109/L], 961 patients in quartile 3 (Q3) [241 ± 11.7 × 109/L], and 982 patients in quartile 4 (Q4) [317 ± 68.6 × 109/L]). There was no significant interaction between treatment arm (ticagrelor vs. prasugrel) and PC group with respect to primary endpoint (Q1: 8.8 vs. 6.3%, hazard ratio [HR] =1.41, 95% confidence interval [CI]: 0.89-2.23; p = 0.148; Q2: 9.9 vs. 5.8%, HR = 1.68, 95% CI: 1.06-2.66; p = 0.027; Q3: 7.8 vs. 5.5%, HR = 1.43, 95% CI: 0.87-2.37; p = 0.159; Q4: 10.1 vs. 10.1%, HR = 1.05, 95% CI: 0.71-1.57; p = 0.799; p for interaction [p int] = 0.482) and with respect to bleeding endpoint (Q1: 5.8 vs. 4.2%, HR = 1.41, 95% CI: 0.76-2.63; p = 0.279; Q2: 6.4 vs. 3.7%, HR = 1.62, 95% CI: 0.85-2.06; p = 0.140; Q3: 4.4 vs. 3.0%, HR = 1.53, 95% CI: 0.73-3.18; p = 0.258; Q4: 5.6 vs. 8.5%, HR = 0.67, 95% CI: 0.40-1.14; p = 0.138, p int = 0.102). CONCLUSIONS In this analysis, incidences of ischemic and bleeding events at 12 months are comparable across quartiles of platelet count.

Abstract
BACKGROUND The percutaneous treatment of severely calcified coronary lesions has been associated with lower performance of coronary stents and poor clinical long-term outcomes. Adequate lesion preparation before stent implantation is of paramount importance to minimize the risk of stent failure. Balloon-based techniques for lesion preparation have been the subject of numerous investigations, albeit comparative data from randomized trials are scarce. STUDY DESIGN AND OBJECTIVES The ISAR-CALC 2 (ClinicalTrials.gov: NCT05072730) is an investigator-initiated, prospective, randomized, multicentre, assessors-blind, open-label trial designed to compare a lesion preparation strategy with either super high-pressure balloon or intravascular lithotripsy (IVL) before drug-eluting stent (DES) implantation in patients with severely calcified, undilatable coronary lesions. In total, 80 patients are required for trial completion. The primary endpoint will be final angiographic minimal lumen diameter (MLD) after stent implantation. Key secondary endpoints include stent expansion assessed by optical coherence tomography (OCT), procedural and strategy success, need for complementary lesion preparation with rotational atherectomy, acute lumen gain, and major adverse cardiac events up to 30-day follow-up. CONCLUSIONS The ISAR-CALC 2 trial aims to demonstrate the superiority of a lesion preparation strategy with a super high-pressure balloon as compared with intravascular lithotripsy prior to DES implantation in patients with severely calcified undilatable coronary lesions.

Coronary artery restenosis treatment with plain balloon, drug-coated balloon, or drug-eluting stent: 10-year outcomes of the ISAR-DESIRE 3 trial. Eur Heart J 2023; 44:1343-1357. [PMID: 36807512 DOI: 10.1093/eurheartj/ehad026] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 12/09/2022] [Accepted: 01/11/2023] [Indexed: 02/23/2023] Open
Abstract
AIMS The best interventional strategy for the treatment of drug-eluting stent (DES) in-stent restenosis (ISR) is still unclear and no data from randomized trials beyond 3-year follow-up are available. We aimed to define 10-year comparative efficacy and safety of plain balloon (PB), paclitaxel-coated balloon (PCB), and paclitaxel-eluting stent (PES) for percutaneous coronary intervention (PCI) of DES-ISR. METHODS AND RESULTS Clinical follow-up of patients randomly assigned to PB, PCB, and PES in the ISAR-DESIRE 3 trial was extended to 10 years and events were independently adjudicated. The primary endpoint was a composite of cardiac death, target vessel myocardial infarction, target lesion thrombosis, or target lesion revascularization. The major secondary safety endpoint was a composite of cardiac death, target vessel myocardial infarction, or target lesion thrombosis. The major secondary efficacy endpoint was target lesion revascularization. Incidences by the Kaplan-Meier method were compared by the log-rank test. Risk estimation was primarily performed by Cox proportional hazards regression and supplemented by weighted Cox regression accounting for non-proportional hazards and Royston-Parmar flexible parametric regression with a time-varying coefficient. Primary results were further assessed by landmark, lesion-level, per-protocol, and competing risk analyses. A total of 402 patients (500 lesions) with DES-ISR were randomly assigned to PB angioplasty (134 patients, 160 lesions), PCB angioplasty (137 patients, 172 lesions), and PES implantation (131 patients, 168 lesions). Clinical follow-up did not significantly differ among treatments [PB, 9.62 (4.50-10.02) years; PCB, 10.01 (5.72-10.02) years; PES, 9.08 (3.14-10.02) years; P = 0.300]. At 10 years, the primary composite endpoint occurred in 90 patients (72.0%) assigned to PB, 70 patients (55.9%) assigned to PCB, and 72 patients (62.4%) assigned to PES (P < 0.001). The pairwise comparison between PCB and PES resulted in a non-significant difference [multiplicity-adjusted P = 0.610; Grambsch-Therneau P = 0.004; weighted Cox: hazard ratio (HR) 1.10, 95% confidence interval (CI) 0.80-1.51; Cox: HR 1.10, 95% CI 0.79-1.52; Royston-Parmar: HR 1.08, 95% CI 0.72-1.60]. The major secondary safety endpoint occurred in 39 patients (34.1%) assigned to PB, 39 patients (34.0%) assigned to PCB, and 42 patients (40.0%) assigned to PES (P = 0.564). Target lesion revascularization occurred in 71 patients (58.0%) assigned to PB, 55 patients (43.9%) assigned to PCB, and 42 patients (38.6%) assigned to PES (P < 0.0001). The pairwise comparison between PES and PCB resulted in a non-significant difference (multiplicity-adjusted P = 0.282; Grambsch-Therneau P = 0.002; weighted Cox: HR 0.83, 95% CI 0.56-1.22; Cox: HR 0.81, 95% CI 0.54-1.21; Royston-Parmar: HR 0.75, 95% CI 0.47-1.20). Lesion-level and per-protocol analyses were consistent. At landmark analyses, an excess of death and cardiac death associated with PES compared with PCB was observed within 5 years after PCI, though 10-year differences did not formally reach the threshold of statistical significance after adjustment for multiplicity. Competing risk regression confirmed a non-significant difference in target lesion revascularization between PCB and PES and showed an increased risk of death associated with PES compared with PCB. CONCLUSION Ten years after PCI for DES-ISR, the primary and major secondary endpoints between PCB and PES were not significantly different. However, an excess of death and cardiac death within 5 years associated with PES and the results of the competing risk analysis are challenging to interpret and warrant further analysis. PES and PCB significantly reduced target lesion revascularization compared with PB.

Ten-year clinical outcomes of drug-eluting stents with different polymer coating strategies by degree of coronary calcification: a pooled analysis of the ISAR-TEST 4 and 5 randomised trials. EUROINTERVENTION 2023; 18:1188-1196. [PMID: 36453826 PMCID: PMC9936252 DOI: 10.4244/eij-d-22-00781] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 09/27/2022] [Indexed: 02/19/2023]
Abstract
BACKGROUND Long-term data concerning the efficacy of different polymer-coating strategies of new-generation drug-eluting stents (DES) in patients with coronary artery calcification (CAC) are scant. AIMS We aimed to investigate 10-year outcomes by degree of CAC after new-generation DES implantation with different polymer-coating strategies. METHODS We analysed individual patient and lesion characteristics of patients randomised to treatment with polymer-free sirolimus-eluting, biodegradable-polymer sirolimus-eluting and permanent-polymer zotarolimus- or everolimus-eluting stents. Endpoints of interest at 10 years were all-cause mortality, myocardial infarction (MI), target lesion revascularisation (TLR) and definite or probable stent thrombosis (ST) according to the degree of CAC (no, mild, moderate or severe) and coating strategy (polymer-free vs biodegradable-polymer vs permanent-polymer). RESULTS A total of 4,953 patients with 6,924 lesions were included. No, mild, moderate or severe CAC was present in 24.5%, 41.8%, 25.8% and 8.0% of patients, respectively. At 10-year follow-up, overall event rates were high, with an incremental increase according to the degree of CAC (all-cause mortality: no 25.3%, mild 32.1%, moderate 41.7%, severe CAC 46.5%; adjusted [adj.] p=0.004; TLR: no 17.4%, mild 16.5%, moderate 19.8%, severe CAC 28.7%; adj. p=0.001; MI: no 4.9%, mild 5.9%, moderate 6.0%, severe CAC 10.5%; adj. p=0.02; and ST: no 1.3%, mild 1.4%, moderate 1.8%, severe CAC 3.6%; adj. p=0.57). In patients with moderate-severe CAC, event rates were comparable, regardless of the DES polymer-coating strategy. CONCLUSIONS At 10 years after PCI with new-generation DES, there was an incremental increase in adverse events by degree of coronary calcification. These detrimental effects do not seem to be impacted by different polymer-coating strategies.

Abstract
BACKGROUND Although some studies have investigated sex-related outcomes up to 5 years after percutaneous coronary intervention (PCI), analyses at longer follow-up (ie, to 10 years) in large cohorts treated exclusively with drug-eluting stent (DES) platforms are lacking. Therefore, this study aimed to define whether sex-related differences in long-term outcomes after PCI persist both in the DES era and at longer-term follow-up. METHODS Individual data of patients treated with DES in 5 randomized controlled trials with 10-year follow-up were pooled. Patients were divided into 2 groups by sex. The analysis of individual participant data was performed using a 1-stage approach by entering a clustering effect by parent study in all univariable and multivariable models focusing on sex. The main outcomes of interest for this analysis included cardiovascular death, myocardial infarction, repeat revascularization, and definite stent thrombosis to 10 years after PCI. Survival was analyzed by the Kaplan-Meier method to estimate the time to first event, and differences between the 2 groups were tested with the log-rank test. Hazard ratios (HRs) and 95% CIs were calculated with a Cox proportional hazards model. Conventional multivariable analyses with adjustment for relevant variables were performed. RESULTS Among 9700 patients undergoing PCI with DES implantation included in the present analysis, 2296 were women and 7404 were men. Through to 10 years, cardiovascular death occurred in 407 of the 2296 female patients and 1012 of the 7404 male patients (adjusted HR [HRadj], 0.94 [95% CI, 0.80-1.11]). Female sex was associated with a lower risk of repeat revascularization of the target lesion (HRadj, 0.80 [95% CI, 0.74-0.87]), target vessel (HRadj, 0.81 [95% CI, 0.76-0.87]), and nontarget vessels (HRadj, 0.69 [95% CI, 0.62-0.77]). Compared with male patients, female patients displayed an increased risk of myocardial infarction in the first 30 days after PCI with DES (HRadj, 1.65 [95% CI, 1.24-2.19]) but a comparable risk of myocardial infarction thereafter. The risk of definite stent thrombosis was not significantly different between female and male patients (HRadj, 1.14 [95% CI, 0.89-1.47]). CONCLUSIONS Through to 10-year follow-up after PCI with DES, female patients are at increased risk of early myocardial infarction, receive fewer repeat revascularizations, and have no difference in cardiovascular mortality compared with male patients.

Iliofemoral artery predilation prior to transfemoral transcatheter aortic valve implantation in patients with aortic valve stenosis and advanced peripheral artery disease. Catheter Cardiovasc Interv 2023; 101:628-638. [PMID: 36709496 DOI: 10.1002/ccd.30576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 10/23/2022] [Accepted: 01/15/2023] [Indexed: 01/30/2023]
Abstract
OBJECTIVES To investigate the feasibility and safety of percutaneous transluminal angioplasty (PTA) of the iliofemoral arteries (IFA) before transfemoral transcatheter aortic valve implantation (Tf-TAVI) in patients with advanced peripheral artery disease (PAD). BACKGROUND Although Tf-TAVI represents the access of choice, alternative vascular access routes are preferred for patients displaying advanced PAD. PTA of the IFA represents a less invasive option, broadening the spectrum of patients eligible for Tf-TAVI. METHODS All patients requiring PTA of the IFA before Tf-TAVI, between 2012 and 2021, were included. Primary efficacy endpoint was the rate of successful transcatheter heart valve (THV) delivery and implantation. Primary safety endpoint was the rate of PTA and access-site-related vascular complications, procedural- and in-hospital complications. RESULTS Among 2726 Tf-TAVI procedures, 59 patients required IFA predilation. Successful THV delivery and implantation was achieved in 57 (96.6%) patients, respectively. Sheath placement was achieved in 59 (100%) patients with only one minor dissection and no major vascular complications following iliofemoral PTA. Regarding access site complications, two (3.4%) vessel perforations and one (1.7%) vessel rupture were observed, with eight (13.5%) patients requiring unplanned endovascular interventions. There was one intraprocedural death due to THV-induced vessel laceration, while in-hospital all-cause mortality was 8.5% in the present high-risk patient cohort. CONCLUSIONS Predilation of IFA is safe and effective in patients with advanced PAD. Careful preprocedural planning is paramount in improving procedural safety and efficacy. This strategy has the potential to broaden the spectrum of patients eligible for Tf-TAVI.

Use of big data from health insurance for assessment of cardiovascular outcomes. Front Artif Intell 2023; 6:1155404.

Abstract
Outcome research that supports guideline recommendations for primary and secondary preventions largely depends on the data obtained from clinical trials or selected hospital populations. The exponentially growing amount of real-world medical data could enable fundamental improvements in cardiovascular disease (CVD) prediction, prevention, and care. In this review we summarize how data from health insurance claims (HIC) may improve our understanding of current health provision and identify challenges of patient care by implementing the perspective of patients (providing data and contributing to society), physicians (identifying at-risk patients, optimizing diagnosis and therapy), health insurers (preventive education and economic aspects), and policy makers (data-driven legislation). HIC data has the potential to inform relevant aspects of the healthcare systems. Although HIC data inherit limitations, large sample sizes and long-term follow-up provides enormous predictive power. Herein, we highlight the benefits and limitations of HIC data and provide examples from the cardiovascular field, i.e. how HIC data is supporting healthcare, focusing on the demographical and epidemiological differences, pharmacotherapy, healthcare utilization, cost-effectiveness and outcomes of different treatments. As an outlook we discuss the potential of using HIC-based big data and modern artificial intelligence (AI) algorithms to guide patient education and care, which could lead to the development of a learning healthcare system and support a medically relevant legislation in the future.

Abstract
Background The efficacy and safety of ticagrelor versus prasugrel in patients with acute coronary syndrome and prior myocardial infarction (MI) remain unstudied. We aimed to assess the treatment effect of ticagrelor versus prasugrel according to prior MI status in patients with ACS. Methods and Results Patients with acute coronary syndrome planned for an invasive strategy and randomized to ticagrelor or prasugrel in the ISAR-REACT (Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment) 5 trial were included. The primary end point was the composite of 1-year all-cause death, MI, or stroke; the secondary safety end point was the composite of 1-year Bleeding Academic Research Consortium type 3 to 5 bleeding. The study included 4015 patients (prior MI=631 patients; no prior MI=3384 patients). As compared with patients without prior MI, the primary end point occurred more frequently in patients with prior MI (12.6% versus 7.2%; hazard ratio [HR], 1.78 [95% CI, 1.38-2.29]); the secondary safety end point appears to differ little between patients with and without prior MI (5.8% versus 5.7%, respectively; HR, 1.02 [95% CI, 0.71-1.45]). With regard to the primary end point, ticagrelor versus prasugrel was associated with an HR of 1.62 (95% CI, 1.03-2.55) in patients with prior MI and an HR of 1.28 (95% CI, 0.99-1.65) in patients without prior MI (Pint=0.37). With regard to the secondary safety end point, ticagrelor versus prasugrel was associated with an HR of 1.28 (95% CI, 0.56-2.91) in patients with prior MI and an HR of 1.13 (95% CI, 0.82-1.55) in patients without prior MI (Pint=0.79). Conclusions Patients with acute coronary syndrome and prior MI are at higher risk for recurrent ischemic but not bleeding events. Prasugrel is superior to ticagrelor in reducing the risk of ischemic events without a tradeoff in bleeding regardless of prior MI status.

The Effect of a Prasugrel- versus a Ticagrelor-based Strategy on Total Ischemic and Bleeding Events in Patients with Acute Coronary Syndromes. EUROPEAN HEART JOURNAL - CARDIOVASCULAR PHARMACOTHERAPY 2022; 9:231-239. [PMID: 36434779 DOI: 10.1093/ehjcvp/pvac067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 10/17/2022] [Accepted: 11/24/2022] [Indexed: 11/27/2022]
Abstract
Abstract
Aims
The effect of a prasugrel versus a ticagrelor based strategy on total (including both first and recurrent) ischemic and bleeding events in patients with acute coronary syndromes (ACS) has not been evaluated. The aim of this analysis was to investigate the treatment effect of a prasugrel versus a ticagrelor based strategy in patients with ACS undergoing an invasive management strategy when both first and recurrent non-fatal ischemic and bleeding events are taken into account.
Methods and Results
This is a post-hoc analysis of the ISAR-REACT-5 randomized control trial, including all 4 018 patients in the trial. The main clinical endpoints of interest included ischemic events (myocardial infarction (MI) and stroke) and bleeding events (Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding). An additional endpoint of interest was definite/probable stent thrombosis. The effect of the prasugrel versus ticagrelor based strategies on these endpoints was evaluated on both time-to-first event and total events analyses. Patients in the prasugrel group had a lower risk of MI in comparison to the ticagrelor group on both time-to-first event (hazard ratio [HR] = 0.61; 95% confidence interval 0.44–0.85) and total events (HR = 0.62 [0.45–0.86]) analysis. The risk of BARC type 3 to 5 bleeding was comparable between the prasugrel and ticagrelor groups on both time-to-first event (HR = 0.96 [0.75–1.25]) and total events (HR = 0.99 [0.76–1.31]) analysis.
Conclusion
A prasugrel based strategy was associated with a reduction in total MI events in comparison to a ticagrelor based strategy in patients with ACS undergoing invasive assessment. Total BARC type 3 to 5 bleeding events were comparable between the two groups. Given the importance of this topic, future studies to confirm these findings would be welcome.

Ten-year patterns of stent thrombosis after percutaneous coronary intervention with new- versus early-generation drug-eluting stents: insights from the DECADE cooperation. REVISTA ESPANOLA DE CARDIOLOGIA (ENGLISH ED.) 2022; 75:894-902. [PMID: 35437213 DOI: 10.1016/j.rec.2022.02.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 02/04/2022] [Indexed: 06/14/2023]
Abstract
INTRODUCTION AND OBJECTIVES The DECADE cooperation is a pooled analysis of individual patient data from drug-eluting stent (DES) trials with a 10-year follow-up. This analysis reports the risk of definite stent thrombosis (ST) through to 10 years after percutaneous coronary intervention (PCI) in patients treated with early- and new-generation DES. METHODS Individual patient data from 5 DES trials with a 10-year follow-up were pooled. The primary endpoint was definite ST up to 10 years after PCI. Patients were divided into 2 groups as per the generation of DES implanted (early and new DES). Individual participant data were analyzed using a 1-stage approach. RESULTS We included 9700 patients, 6866 in the new DES group and 2834 in the early DES group. Through to 10 years, definite ST occurred in 69 of 6866 patients treated with new DES and in 91 of 2834 patients treated with early DES (1.0% vs 3.5%, adjusted hazard ratio, 0.32; 95%CI, 0.23-0.45). The rate of definite ST was lower in the new DES group than in the early DES group from 1 to 5 years (rate ratio, 0.14; 95%CI, 0.08-0.26) and from 5 to 10 years (rate ratio, 0.23; 95%CI, 0.08-0.61) after PCI. CONCLUSIONS The incidence of definite ST through to 10 years after PCI with new-generation DES was 1%. New-generation DES are associated with a lower 10-year incidence of definite ST than early-generation DES, particularly beyond 1 year after PCI.

Abstract
Abstract
Background
Recent advancements in recanalization techniques, introduction of dedicated equipment and elaboration of systematic algorithmic approaches have significantly improved procedural success of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) procedures. However, despite their undisputable merits in terms of procedural success, direct comparisons of mid-term clinical and angiographic outcomes following CTO and non-CTO-PCI are missing.
Purpose
The aim of this study was to assess the clinical and angiographic outcomes of patients undergoing successful CTO-PCI as compared to a propensity matched cohort of patients undergoing PCI of non-occlusive coronary lesions.
Methods
All consecutive patients undergoing successful CTO recanalization procedures at our center between 2015 and 2018 were included (N=453; 472 lesions). For matching purposes, all patients undergoing non-CTO-PCI present in our database were included (N=14733; 23458 lesions). A 1-to-1 nearest neighbour matching using baseline clinical and angiographic variables was performed to identify one patient undergoing non-CTO-PCI (N=453; 472 vessels) for each patient undergoing CTO-PCI (N=453; 472 vessels). Surveillance angiography was scheduled at 6–9 months and clinical follow-up was performed up to 12 months. The primary clinical endpoint of interest was the incidence of major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR). The secondary angiographic endpoint was in-segment binary restenosis.
Results
Patients undergoing CTO-PCI displayed a tendency towards higher degrees of binary restenosis at surveillance angiography as compared to those undergoing non-CTO-PCI (CTO vs. non-CTO: 30.5% vs. 24.0%; P=0.058), despite not meeting statistical significance. Of note, the incidence of occlusive restenosis was low and comparable between groups (2.2% vs. 1.4%; P=0.603). At 12 months follow-up, MACE occurred in 83 patients (19.7%) in the CTO-PCI and 59 patients (14.1%) in the non-CTO-PCI group (hazard ratio [HR] = 1.44; 95% confidence interval [CI]: 1.03–2.01; P=0.033). TLR rates were significantly higher following CTO- as compared to non-CTO-PCI (17.2% vs. 10.3%; HR=1.72 [1.18–2.51], P=0.005). The incidence of all-cause death (2.6% vs. 3.3%; P=0.548) and MI (0.5% vs. 1.4%; P=0.177) was not significantly different between the groups.
Conclusion
In this large, propensity-matched comparison of clinical and angiographic outcomes following CTO- vs. non-CTO-PCI, we found CTO-PCI to be associated with a higher MACE rate at 12 months, primarily driven by significantly higher TLR rates. The incidence of occlusive restenosis was low and comparable between groups.

Abstract
Abstract
Background
The relative efficacy and safety of more potent P2Y12 inhibitors in patients with acute coronary syndrome (ACS) and high bleeding risk (HBR) undergoing percutaneous coronary intervention (PCI) remains unclear.
Purpose
To study the treatment effect of ticagrelor and prasugrel in PCI patients presenting with ACS and HBR.
Methods
This post-hoc analysis of the ISAR-REACT 5 trial included patients with ACS undergoing PCI, randomized to ticagrelor or prasugrel, in whom HBR was defined as per Academic Research Consortium criteria. The primary (efficacy) endpoint was the composite of all-cause death, myocardial infarction, or stroke. The secondary (safety) endpoint was Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding. Outcomes were assessed 12 months after randomisation.
Results
Out of the 3,239 patients included in this analysis, 486 fulfilled the criteria for ARC-HBR definition (HBR group; ticagrelor, n=230 and prasugrel, n=256), whilst 2,753 did not (non-HBR group; ticagrelor, n=1,375 and prasugrel, n=1,378). Compared to the non-HBR group, the HBR group had a higher risk for the primary (hazard ratio [HR]=3.57, 95% confidence interval [CI], 2.79–4.57, p<0.001), and secondary endpoint (HR=2.94 [2.17–3.99], p<0.001). In the HBR group, the primary (HR=1.09; [0.73–1.62]) and secondary (HR=1.18 [0.67–2.08]) endpoints were not statistically different between patients assigned to ticagrelor and prasugrel. In the non-HBR group, the primary endpoint (HR=1.62 [1.19–2.20]) occurred more frequently in patients assigned to ticagrelor as compared to patients assigned to prasugrel, without difference in safety (HR=1.08 [0.74–1.58]). There was no treatment allocation-by-HBR status interaction with respect to the primary (p for interaction = 0.123), or secondary (p for interaction = 0.803) endpoints.
Conclusions
In patients with ACS undergoing PCI, HBR status increased both ischemic and bleeding risks without significant impact on the relative efficacy or safety of ticagrelor versus prasugrel. These results warrant confirmation in larger cohorts.

Abstract
Objectives
To investigate the efficacy and safety of ticagrelor versus prasugrel in patients with acute coronary syndrome (ACS) and prior myocardial infarction (MI).
Background
The efficacy and safety of ticagrelor versus prasugrel in ACS patients with prior MI remains unstudied.
Methods
Patients with ACS scheduled for an invasive strategy and randomized to ticagrelor or prasugrel in the ISAR-REACT 5 trial with available information concerning prior MI were included in the present analysis. The primary endpoint was the composite of all-cause death, myocardial infarction, or stroke; the secondary endpoint was Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding. Endpoints were assessed 12 months after randomization.
Results
A total of 4,015 patients were included in this analysis (prior MI= 631 patients; no prior MI = 3,384 patients). As compared to patients without prior MI, the primary endpoint occurred more frequently in patients with prior MI (12.6% vs. 7.2%; hazard ratio [HR] = 1.78, 95% confidence interval [CI] 1.38–2.29; p= <0.001) without significant difference in terms of secondary endpoint between groups (5.8% vs. 5.7%; HR=1.02 [0.71–1.45]; p=0.921). Patients with prior MI randomized to ticagrelor versus prasugrel displayed higher risk for primary (HR=1.62 [1.03–2.55]) but not secondary endpoint (HR=1.28 [0.56–2.91]). Patients without prior MI randomized to ticagrelor or prasugrel displayed no significant difference in terms of primary (HR=1.28 [0.99–1.65]) or secondary endpoints (HR=1.13 [0.82–1.55]). There was no treatment assignment-by-prior MI status interaction with respect to the primary (p for interaction = 0.373) and the secondary (p for interaction= 0.786) endpoints.
Conclusions
Patients with ACS and prior MI are at higher risk for recurrent ischemic but not bleeding events. The history of MI does not affect the relative efficacy and safety of ticagrelor versus prasugrel in patients with ACS.

Abstract
BACKGROUND The relative efficacy and safety of more potent P2Y12 inhibitors in patients with acute coronary syndrome and high bleeding risk (HBR) undergoing percutaneous coronary intervention remains unclear. We aimed to study the treatment effect of ticagrelor and prasugrel in percutaneous coronary intervention patients presenting with acute coronary syndrome and HBR. METHODS This post hoc analysis of the ISAR-REACT 5 trial (Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment 5) included patients with acute coronary syndrome undergoing percutaneous coronary intervention, randomized to ticagrelor or prasugrel, in whom HBR was defined as per Academic Research Consortium criteria. The primary (efficacy) end point was the composite of all-cause death, myocardial infarction, or stroke. The secondary (safety) end point was Bleeding Academic Research Consortium type 3 to 5 bleeding. Outcomes were assessed 12 months after randomization. RESULTS Out of the 3239 patients included in this analysis, 486 fulfilled the criteria for Academic Research Consortium-HBR definition (HBR group; ticagrelor, n=230 and prasugrel, n=256), while 2753 did not (non-HBR group; ticagrelor, n=1375 and prasugrel, n=1378). Compared with the non-HBR group, the HBR group had a higher risk for the primary (hazard ratio [HR]=3.57 [95% CI, 2.79-4.57]; P<0.001) and secondary end point (HR=2.94 [2.17-3.99]; P<0.001). In the HBR group, the primary (HR=1.09 [0.73-1.62]) and secondary (HR=1.18 [0.67-2.08]) end points were not significantly different between patients assigned to ticagrelor and prasugrel. In the non-HBR group, the primary end point (HR=1.62 [1.19-2.20]) occurred more frequently in patients assigned to ticagrelor as compared to patients assigned to prasugrel, without difference in safety (HR=1.08 [0.74-1.58]). There was no significant treatment allocation-by-HBR status interaction with respect to the primary (P for interaction=0.12) or secondary (P for interaction=0.80) end points. CONCLUSIONS In patients with acute coronary syndrome undergoing percutaneous coronary intervention, HBR status increased both ischemic and bleeding risk without significant impact on the relative efficacy and safety of either ticagrelor or prasugrel. These results warrant confirmation in larger cohorts. REGISTRATION URL: https://www. CLINICALTRIALS gov; Unique identifier: NCT01944800.

Abstract
AIMS To assess whether the efficacy and safety of ticagrelor vs. prasugrel in patients with acute coronary syndromes (ACSs) are influenced by pre-admission treatment with aspirin and/or clopidogrel. METHODS AND RESULTS Patients (n = 4018) were categorized into two groups: pre-admission aspirin and/or clopidogrel group (n = 1455) and no pre-admission aspirin or clopidogrel group (n = 2563). The primary endpoint was the composite of all-cause death, myocardial infarction, or stroke; the secondary safety endpoint was Bleeding Academic Research Consortium (BARC) type 3-5 bleeding, both at 1 year. Patients in the pre-admission aspirin and/or clopidogrel group had a higher risk of ischaemic events, but a similar risk of bleeding to patients in the no pre-admission aspirin or clopidogrel group (cumulative incidences 10.5% vs. 6.7%, and 5.7% vs. 5.7%, respectively). The primary endpoint occurred in 81/717 patients assigned to ticagrelor and 69/738 patients assigned to prasugrel in the pre-admission aspirin and/or clopidogrel group [11.5% vs. 9.5%; hazard ratio (HR) = 1.23; 95% confidence interval (CI) 0.89-1.69], and in 103/1295 patients assigned to ticagrelor and 68/1268 patients assigned to prasugrel in the no pre-admission aspirin or clopidogrel group [8.0% vs. 5.4%; HR = 1.50 (1.10-2.03); Pint = 0.38]. BARC type 3-5 bleeding events did not differ between ticagrelor and prasugrel in patients in the pre-admission aspirin and/or clopidogrel (6.2% vs. 4.5%) or no pre-admission aspirin or clopidogrel (5.3% vs. 5.1%) group (Pint = 0.54). CONCLUSION In patients with ACS, pre-admission therapy with aspirin and/or clopidogrel has no influence on the relative efficacy and safety of ticagrelor and prasugrel.

Abstract
BACKGROUND The comparative efficacy of percutaneous techniques for the preparation of calcified lesions before stenting remains poorly studied. OBJECTIVES This study sought to compare the performance of up-front rotational atherectomy (RA) or balloon-based techniques before drug-eluting stent implantation in severely calcified coronary lesions as assessed by angiography and optical coherence tomography (OCT). METHODS Patient-level data from the PREPARE-CALC (Comparison of Strategies to Prepare Severely Calcified Coronary Lesions) and ISAR-CALC (Comparison of Strategies to Prepare Severely Calcified Coronary Lesions) randomized trials were pooled. The primary endpoint was stent expansion as assessed by OCT imaging. The secondary endpoints included stent eccentricity, stent asymmetry, angiographic acute lumen gain, strategy success and in-hospital occurrence of cardiac death, target vessel myocardial infarction, and repeat revascularization. RESULTS Among 274 patients originally randomized, 200 participants with available OCT data after lesion preparation with RA (n = 63), a modified balloon (MB, n = 103), or a super high-pressure balloon (n = 34) before stenting were analyzed. The use of RA versus MB or a super high-pressure balloon led to comparable stent expansion (73.2% ± 11.6% vs 70.8% ± 13.6% vs 71.8% ± 12.2%, P = 0.49) and stent asymmetry (P = 0.83). Compared with RA or MB, a super high-pressure balloon was associated with less stent eccentricity (P = 0.03) with a numerically higher acute lumen gain, albeit not significantly different (P = 0.08). Strategy success was more frequent with RA versus MB (P = 0.002) and numerically more frequent with RA versus a super high-pressure balloon (P = 0.06). Clinical outcomes did not differ between groups. CONCLUSIONS In patients with severely calcified lesions undergoing drug-eluting stent implantation, lesion preparation with RA, MB, or a super high-pressure balloon was associated with comparable stent expansion. A super high-pressure balloon is associated with less stent eccentricity, whereas strategy success is more frequent with RA.

Abstract
INTRODUCTION AND OBJECTIVES The efficacy and safety of ticagrelor vs prasugrel in patients with acute coronary syndromes (ACS) according to body mass index (BMI) remain unstudied. We assessed the efficacy and safety of ticagrelor vs prasugrel in patients with ACS according to BMI. METHODS Patients (n=3987) were grouped into 3 categories: normal weight (BMI <25kg/m2; n=1084), overweight (BMI ≥ 25 to <30kg/m2; n=1890), and obesity (BMI ≥ 30kg/m2; n=1013). The primary efficacy endpoint was the 1 year incidence of all-cause death, myocardial infarction, or stroke. The secondary safety endpoint was the 1 year incidence of Bleeding Academic Research Consortium type 3 to 5 bleeding. RESULTS The primary endpoint occurred in 63 patients assigned to ticagrelor and 39 patients assigned to prasugrel in the normal weight group (11.7% vs 7.5%; HR, 1.62; 95%CI, 1.09-2.42; P=.018), 78 patients assigned to ticagrelor and 58 patients assigned to prasugrel in the overweight group (8.3% vs 6.2%; HR, 1.36; 95%CI, 0.97-1.91; P=.076), and 43 patients assigned to ticagrelor and 37 patients assigned to prasugrel in the obesity group (8.6% vs 7.3%; HR, 1.18; 95%CI, 0.76-1.84; P=.451). The 1-year incidence of bleeding events did not differ between ticagrelor and prasugrel in patients with normal weight (6.5% vs 6.6%; P=.990), overweight (5.6% vs 5.0%; P=.566) or obesity (4.4% vs 2.8%; P=.219). There was no significant treatment arm-by-BMI interaction regarding the primary endpoint (Pint=.578) or secondary endpoint (Pint=.596). CONCLUSIONS In patients with ACS, BMI did not significantly impact the treatment effect of ticagrelor vs prasugrel in terms of efficacy or safety. CLINICAL TRIAL REGISTRATION NCT01944800.

Abstract
Background Anemia and blood loss occur often in patients with ST‐segment–elevation myocardial infarction (STEMI). In‐hospital hemoglobin drop is associated with 1‐year mortality in patients with acute coronary syndrome. However, data on the effect of hemoglobin reduction on myocardial salvage and long‐term outcomes are scarce. We investigated the impact of in‐hospital hemoglobin drop on myocardial salvage and 5‐year mortality in patients with STEMI treated with primary percutaneous coronary intervention. Methods and Results In‐hospital hemoglobin drop was defined as a decrease in hemoglobin levels from admission and nadir hemoglobin values. Patients were categorized as having the following: no drop, minimal drop (<3 g/dL), minor drop (≥3 to <5 g/dL), and major drop (≥5 g/dL). Myocardial area at risk and infarct size were measured using serial single‐photon emission computerized tomography imaging. The co‐primary outcomes were myocardial salvage and 5‐year all‐cause mortality. Of 1204 patients, 1169 (97.1%) showed a hemoglobin drop during hospitalization: minimal, minor, and major drop occurred in 894 (74.3%), 214 (17.8%), and 61 (5.1%) patients, respectively. Myocardial salvage was reduced in patients with minimal (median, 0.53 [interquartile range, 0.27–0.83]), minor (median, 0.40 [interquartile range, 0.18–0.62]), and major (median, 0.40 [interquartile range, 0.14–0.77]) drop compared with patients without drop (median, 0.70 [interquartile range, 0.44–1.0], P<0.001). After adjusting for covariates, hemoglobin drop remained an independent correlate of poor myocardial salvage. A drop of ≥3 g/dL was associated with reduced left ventricular function at 6 months and with increased mortality at 5‐year follow‐up after STEMI. Conclusions In patients with STEMI undergoing primary percutaneous coronary intervention, in‐hospital hemoglobin drop was associated with reduced myocardial salvage, left ventricular function, and increased long‐term mortality.

Abstract
OBJECTIVES To assess the efficacy and safety of ticagrelor versus prasugrel in patients with acute coronary syndrome (ACS) presenting during off- and on-hours. BACKGROUND The efficacy and safety of ticagrelor versus prasugrel in patients with ACS according to time of hospital presentation remain unknown. METHODS This post hoc analysis of the ISAR-REACT 5 trial included 1565 patients with ACS presenting off-hours and 2453 patients presenting on-hours, randomized to ticagrelor or prasugrel. The primary endpoint was a composite of death, myocardial infarction, or stroke; the safety endpoint was Bleeding Academic Research Consortium (BARC) type 3-5 bleeding, both at 12 months. RESULTS The primary endpoint occurred in 80 patients (10.4%) in the ticagrelor group and 57 patients (7.3%) in the prasugrel group in patients presenting off-hours (hazard ratio [HR] = 1.45; 95% confidence interval [CI] 1.03-2.03; P = 0.033), and 104 patients (8.5%) in the ticagrelor group and 80 patients (6.7%) in the prasugrel group in patients presenting on-hours (HR = 1.29 [0.97-1.73]; P = 0.085), without significant treatment arm-by-presentation time interaction (Pint = 0.62). BARC type 3 to 5 bleeding occurred in 35 patients (5.1%) in the ticagrelor group and 37 patients (5.3%) in the prasugrel group (P = 0.84) in patients presenting off-hours, and 60 patients (5.9%) in the ticagrelor group and 43 patients (4.6%) in the prasugrel group in patients presenting on-hours (P = 0.17). CONCLUSIONS In patients with ACS planned to undergo an invasive treatment strategy, time of presentation (off-hours vs. on-hours) does not interact significantly with the relative efficacy and safety of ticagrelor vs. prasugrel.

Abstract
Summary: Background: The influence of diabetes mellitus (DM) on recurrent in-stent restenosis (ISR) of femoropopliteal arteries remains understudied. We investigated whether DM has an impact on recurrent restenosis after femoropopliteal stenting in patients included in the dRug-coatEd balloon angioPlasty for femoropopliteAl In-stent Restenosis (REPAIR) cooperation. Patients and methods: The REPAIR cooperation pooled the patient-level data from 3 randomized trials in which patients with ISR of femoropopliteal arteries received either drug-coated balloon (DCB) or plain balloon angioplasty. For this analysis, patients were divided in two groups based on whether they had or had not a DM diagnosis at the time of enrollment. The primary outcome was target lesion revascularization (TLR). The main secondary outcome was recurrent ISR. Other outcomes of interest were death, Rutherford class improvement and ankle-brachial index at follow-up. Results: 256 patients (DM, n=99 vs. non-DM, n=157) with 12-month follow-up were included in the analysis. Compared to non-DM patients, DM patients displayed no difference in terms of TLR [adjusted hazard ratio (95% Confidence intervals): 0.96 (0.55, 1.69), p=0.89] and recurrent ISR [1.04 (0.61, 1.77), p=0.88], whilst mortality was higher [9.38 (1.06, 83.11), p=0.044]. There were no differences between groups with respect to other secondary outcomes. The percutaneous treatment with DCB as compared to plain balloon angioplasty significantly reduced the risk of TLR and recurrent ISR without an excess risk of death irrespective of DM (p for interaction ≥0.70). Conclusions: In patients with femoropopliteal ISR, diabetes has a neutral effect on the risk of recurrence, but increases mortality at 12-month follow-up. DCB as compared to plain balloon angioplasty is associated with superior efficacy without trade-off in safety, regardless of diabetes.

Abstract
BACKGROUND The association between alkaline phosphatase (ALP) and mortality in patients with diabetes mellitus (DM) and ischemic heart disease (IHD) remains poorly investigated. METHODS The study included 1426 patients with DM and IHD who underwent percutaneous coronary intervention. Patients were divided in groups according to tertiles of ALP activity: a group with ALP activity in 1st tertile (ALP activity: 20.8-65.0 U/L; n = 478), a group with ALP activity in 2nd tertile (ALP activity: 65.1-87.0 U/L; n = 473) and a group with ALP activity in 3rd tertile (ALP activity: 87.1-1520 U/L; n = 475). The primary endpoint was 3-year all-cause mortality. RESULTS At 3 years, all-cause deaths occurred in 182 patients: 50 deaths (12.4%) in patients of 1st tertile, 47 deaths (11.7%) in patients of 2nd tertile and 85 deaths (20.8%) in patients of 3rd tertile of ALP activity (adjusted hazard ratio [HR] = 1.20, 95% confidence interval [CI] 1.02 to 1.42, P = 0.031); cardiac deaths occurred in 110 patients: 28 deaths (7.0%) in patients of 1st tertile, 30 deaths (7.6%) in patients of 2nd tertile and 52 deaths (12.7%) in patients of 3rd tertile of ALP activity (adjusted HR = 1.27 [1.04-1.56], P = 0.021, with both risk estimates calculated for unit increment in the log scale of ALP activity). The C-statistic of the multivariable model with baseline data without and with ALP was 0.787 [0.750-0.818] and 0.804 [0.757-0.851], (P = 0.575) for all-cause mortality and 0.832 [0.798-0.864] and 0.876 [0.833-0.918], (P = 0.115) for cardiac mortality. CONCLUSIONS In patients with DM and IHD, elevated ALP activity was associated with increased risk of 3-year mortality.

Abstract
BACKGROUND Whether bleeding and myocardial infarction (MI) improve the performance of risk prediction models for mortality in patients with acute coronary syndromes (ACS) treated with percutaneous coronary intervention (PCI) remains unknown. METHODS This study included 3377 patients with ACS who underwent PCI in the setting of the ISAR-REACT 5 trial. Patients with bleeding, MI or those dying at 1 year after PCI were characterized in terms of baseline characteristics, risk estimates and C-statistic of the risk prediction models for these outcomes. RESULTS Major bleeding (Bleeding Academic Research Consortium types 3-5), MI and mortality occurred in 195 patients (5.8%), 143 patients (4.3%) and 143 patients (4.3%), respectively. After adjustment, bleeding [hazard ratio = 5.08; 95% confidence interval (CI), 3.03-8.53; P < 0.001] and MI [hazard ratio = 5.90; 95% CI, (3.00-11.65); P < 0.001) remained independently associated with the risk for 1-year mortality. The C-statistic (with 95% CI) of the model for bleeding, MI and mortality was, 0.755 (0.722-0.786), 0.752 (0.717-0.789) and 0.868 (0.837-0.896), respectively. The inclusion of bleeding [C-statistic: 0.892 (0.867-0.913); delta C-statistic 0.024 (-0.014 to 0.065); P = 0.200] or MI [C-statistic: 0.878 (0.851-0.903); delta C-statistic 0.011 (-0.030 to 0.053); P = 0.635] in the risk prediction models for mortality alongside baseline demographical and clinical variables did not improve prediction for mortality. CONCLUSIONS In patients with ACS treated with PCI, mortality is the most accurately predicted outcome. Bleeding and MI did not improve risk discrimination for mortality when added in the risk prediction models for mortality suggesting that these outcomes do not provide incremental prognostic information on top of baseline demographical and clinical data.

Periprocedural myocardial injury according to optical characteristics of neointima and treatment modality of in-stent restenosis. Clin Res Cardiol 2022; 111:827-837. [PMID: 35476138 PMCID: PMC9242953 DOI: 10.1007/s00392-022-02024-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 04/06/2022] [Indexed: 02/07/2023]
Abstract
Aims Aim of the present study was to investigate the impact of increasing neointimal inhomogeneity and neoatherosclerosis as well as of treatment modality of in-stent restenosis (ISR) on the occurrence of periprocedural myocardial injury (PMI). Methods and results Patients with normal or stable/falling increased baseline high-sensitivity troponin T (hs-cTnT) undergoing intravascular optical coherence tomography (OCT) and subsequent percutaneous coronary intervention (PCI) of ISR by means of drug-coated balloon (DCB) or drug-eluting stent (DES) were included. Overall, 128 patients were subdivided into low (n = 64) and high (n = 64) inhomogeneity groups, based on the median of distribution of non-homogeneous quadrants. No significant between-group differences were detected in terms of hs-cTnT changes (28.0 [12.0–65.8] vs. 25.5 [9.8–65.0] ng/L; p = 0.355), or the incidence of major PMI (31.2 vs. 31.2%; p = 1.000). Similarly, no differences were observed between DCB- and DES-treated groups in terms of hs-cTn changes (27.0 [10.0–64.0] vs. 28.0 [11.0–73.0] ng/L; p = 0.795), or the incidence of major PMI (28.9 vs. 35.6%; p = 0.566). Additionally, no significant interaction was present between optical neointimal characteristics and treatment modality in terms of changes in hs-cTnT (Pint = 0.432). No significant differences in PMI occurrence were observed between low and high neoatherosclerosis subgroups. Conclusions In patients undergoing PCI for ISR, there was no association between increasing neointimal inhomogeneity, or increasing expression of neoatherosclerotic changes and occurrence of PMI. PMI occurrence was not influenced by the treatment modality (DCB vs. DES) of ISR lesions, a finding that supports the safety of DCB treatment for ISR. Graphical abstract ![]()

Abstract
Background Stent underexpansion has been known to be associated with worse outcomes. We sought to define optical coherence tomography assessed optimal stent expansion index (SEI), which associates with lower incidence of follow-up major adverse cardiac events (MACEs). Methods and Results A total of 315 patients (involving 370 lesions) who underwent optical coherence tomography-aided coronary stenting were retrospectively included. SEI was calculated separately for equal halves of each stented segment using minimum stent area/mean reference lumen area ([proximal reference area+distal reference area]/2). The smaller of the 2 was considered to be the SEI of that case. Follow-up MACE was defined as a composite of all-cause death, myocardial infarction, stent thrombosis, and target lesion revascularization. Average minimum stent area was 6.02 (interquartile range, 4.65-7.92) mm2, while SEI was 0.79 (interquartile range, 0.71-0.86). Forty-seven (12.7%) incidences of MACE were recorded for 370 included lesions during a median follow-up duration of 557 (interquartile range, 323-1103) days. Receiver operating characteristic curve analysis identified 0.85 as the best SEI cutoff (<0.85) to predict follow-up MACE (area under the curve, 0.60; sensitivity, 0.85; specificity, 0.34). MACE was observed in 40 of 260 (15.4%) lesions with SEI <0.85 and in 7 of 110 (6.4%) lesions with SEI ≥0.85 (P=0.02). Least absolute shrinkage and selection operator regression identified SEI <0.85 (odds ratio, 3.55; 95% CI, 1.40-9.05; P<0.01) and coronary calcification (odds ratio, 2.47; 95% CI, 1.00-6.10; P=0.05) as independent predictors of follow-up MACE. Conclusions The present study identified SEI <0.85, associated with increased incidence of MACE, as the optimal cutoff in daily practice. Along with suboptimal SEI (<0.85), coronary calcification was also found to be a significant predictor of follow-up MACE.
