Abstract
Heart failure has a poor prognosis and no curative treatment exists. Clinical trials are investigating gene- and cell-based therapies to improve cardiac function. The safe and efficient delivery of these therapies to solid organs is challenging. Herein, we demonstrate the feasibility of using an endovascular intramyocardial delivery approach to safely administer mRNA drug products and perform cell transplantation procedures in swine. Using a trans-vessel wall (TW) device, we delivered chemically modified mRNAs (modRNA) and mRNA-enhanced mesenchymal stromal cells expressing vascular endothelial growth factor A (VEGF-A) directly to the heart. We monitored and mapped the cellular distribution, protein expression, and safety tolerability of such an approach. The delivery of modRNA-enhanced cells via the TW device with different flow rates and cell concentrations marginally affect cell viability and protein expression in situ. Implanted cells were found within the myocardium for at least 3 days following administration, without the use of immunomodulation and minimal impact on tissue integrity. Finally, we could increase the protein expression of VEGF-A over 500-fold in the heart using a cell-mediated modRNA delivery system compared with modRNA delivered in saline solution. Ultimately, this method paves the way for future research to pioneer new treatments for cardiac disease.

Coronary surgery provides better survival than drug-eluting stent: A pooled meta-analysis of Kaplan-Meier-derived individual patient data. J Thorac Cardiovasc Surg 2024; 167:2138-2146.e3. [PMID: 37001801 DOI: 10.1016/j.jtcvs.2023.03.020] [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: 12/11/2022] [Revised: 03/15/2023] [Accepted: 03/21/2023] [Indexed: 04/23/2023]
Abstract
OBJECTIVES We explored the current evidence on coronary disease treatment comparing the survival of 2 therapeutic strategies: coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with drug-eluting stent (DES). METHODS PubMed, Embase, and Google Scholar were searched for randomized clinical trials comparing CABG versus PCI with DES. The end point was overall mortality. Two statistical approaches were used: the generic inverse variance method, which was used to pool the incident rate ratios, and the pooled meta-analysis of Kaplan-Meier-derived individual patient data. RESULTS Eight randomized clinical trials comparing 4975 patients undergoing CABG and 4992 patients undergoing PCI were included in our meta-analysis. Generic inverse variance method showed a statistically significant survival benefit of the CABG group (incident rate ratio, 1.21; 95% confidence interval, 1.09-1.35; P < .01). The Kaplan-Meier estimates of survival at 1, 5, and 10 years of the CABG group were 97.1%, 90.3%, and 80.3%, respectively. The Kaplan-Meier estimates of survival at 1, 5, and 10 years of the PCI group were 97.0%, 87.7%, and 76.4%, respectively. The log-rank analysis confirmed a statistically significant benefit in term of overall mortality of the CABG group (hazard ratio, 1.24; 95% confidence interval, 1.11-1.38; P = .0001). CONCLUSIONS The present meta-analysis suggests that CABG provides a consistent survival benefit over PCI with DES.

Long-term survival outcomes of esophagectomy with off-pump CABG versus esophagectomy alone. Surg Endosc 2024:10.1007/s00464-024-10822-x. [PMID: 38782826 DOI: 10.1007/s00464-024-10822-x] [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: 12/29/2023] [Accepted: 03/22/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND This study aimed to evaluate the long-term survival outcomes of esophagectomy with off-pump coronary artery bypass grafting (OPCABG) vs. esophagectomy alone. METHODS A total of 1798 patients who received esophagectomy between January 2010 and February 2020 were included and divided into the 38 patients who underwent OPCABG followed by esophagectomy (OP + ES group) and 1760 patients had only esophagectomy (ES group). Propensity score matching (PSM) and Cox multivariable analyses were performed to compare postoperative complications, disease-free survival (DFS), and overall survival (OS) between the two groups. RESULTS There were 37 patients in the OP + ES group matched with 74 in the ES group. The matched OP + ES group had higher total postoperative complications than the ES group, especially more pulmonary infections (P = 0.001) and arrhythmias (P = 0.018), but no other postoperative complications were the difference. The DFS was similar and the OS was a significant difference between the matching 2 groups (log-rank, P = 0.132 and 0.04, respectively). Although pT 3/4 stage, pN (+), and tumor length > 3.0 cm were independently associated with worse OS and DFS in multivariable analysis, CAD and EF < 55% were also found to be a predictive factor for OS and DFS in univariate analysis. CONCLUSION OPCABG followed by esophagectomy for esophageal cancer associated with coronary artery disease has equivalent DFS and recurrence pattern to esophagectomy for esophageal cancer alone, but with a disadvantage in OS.

Identifying coronary artery bypass grafting patients at high risk for adverse long-term prognosis using serial health-related quality of life assessments. Chin Med J (Engl) 2024; 137:1069-1077. [PMID: 37620281 PMCID: PMC11062708 DOI: 10.1097/cm9.0000000000002806] [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: 02/06/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Patients who undergo coronary artery bypass grafting (CABG) are known to be at a significant risk of experiencing long-term adverse events, emphasizing the importance of regular assessments. Evaluating health-related quality of life (HRQoL) serves as a direct method to gauge prognosis. Our objective is to ascertain the prognostic significance of consecutive HRQoL assessments using the Physical Component Summary (PCS) and Mental Component Summary (MCS) derived from the Short-Form 36 (SF-36) health survey in CABG patients. METHODS The study population consisted of 433 patients who underwent isolated elective CABG at Fuwai Hospital between 2012 and 2013. SF-36 assessments were conducted during both the hospitalization period and follow-up. The primary endpoint of the study was all-cause mortality, while the secondary outcome was a composite measure including death, myocardial infarction, stroke, and repeat revascularization. We assessed the relationships between the PCS and MCS at baseline, as well as their changes during the first 6 months after the surgery (referred to as ΔPCS and ΔMCS, respectively), and the observed outcomes. RESULTS The patients were followed for an average of 6.28 years, during which 35 individuals (35/433, 8.1%) died. After adjusting for clinical variables, it was observed that baseline MCS scores (hazard ratio [HR] for a 1-standard deviation [SD] decrease, 1.57; 95% confidence interval [CI], 1.07-2.30) and ΔMCS (HR for a 1-SD decrease, 1.67; 95% CI, 1.09-2.56) were associated with all-cause mortality. However, baseline PCS scores and ΔPCS did not exhibit a significant relationship with all-cause mortality. Notably, there was a dose-response relationship observed between ΔMCS and the likelihood of all-cause mortality (HRs for the 2nd, 3rd and 4th quartiles compared to the 1st quartile, 0.33, 0.45 and 0.11, respectively). CONCLUSIONS Baseline MCS and changes in MCS were independent predictors for long-term mortality of CABG. Better mental health status and recovery indicated better prognosis.

Abstract
Revascularization is an effective adjunct to medical therapy for some patients with chronic coronary disease. Despite numerous randomized trials, there remains significant uncertainty regarding if and how to revascularize many patients. Coronary artery bypass grafting is a class I indication for patients with significant left main stenosis or multivessel disease with ejection fraction ≤ 35%. For other patients, clinicians must carefully consider the potential benefits of symptom improvement and reduction of future myocardial infarction or CV death against the risk and cost of revascularization. Although guidelines provide a framework for these decisions, each individual patient will have distinct coronary anatomy, clinical factors, and preferences.

Results beyond 5-years of surgery or percutaneous approach in severe coronary disease. Reconstructed time-to-event meta-analysis of randomized trials. REVISTA ESPANOLA DE CARDIOLOGIA (ENGLISH ED.) 2024; 77:383-392. [PMID: 37816454 DOI: 10.1016/j.rec.2023.09.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 09/20/2023] [Indexed: 10/12/2023]
Abstract
INTRODUCTION AND OBJECTIVES There is controversy about the optimal revascularization strategy in severe coronary artery disease (CAD), including left main disease and/or multivessel disease. Several meta-analyses have analyzed the results at 5-year follow-up but there are no results after the fifth year. We conducted a systematic review and meta-analysis of randomized clinical trials, comparing results after the fifth year, between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) using drug-eluting stents in patients with severe CAD. METHODS We analyzed all clinical trials between January 2010 and January 2023. The primary endpoint was all-cause mortality. The databases of the original articles were reconstructed from Kaplan-Meier curves, simulating an individual-level meta-analysis. Comparisons were made at certain cutoff points (5 and 10 years). The 10-year restricted median survival time difference between CABG and PCI was calculated. The random effects model and the DerSimonian-Laird method were applied. RESULTS The meta-analysis included 5180 patients. During the 10-year follow-up, PCI showed a higher overall incidence of all-cause mortality (HR, 1.19; 95%CI, 1.04-1.32; P=.008)]. PCI showed an increased risk of all-cause mortality within 5 years (HR, 1.2; 95%CI, 1.06-1.53; P=.008), while no differences in the 5-10-year period were revealed (HR, 1.03; 95%CI, 0.84-1.26; P=.76). Life expectancy of CABG patients was slightly higher than that of PCI patients (2.4 months more). CONCLUSIONS In patients with severe CAD, including left main disease and/or multivessel disease, there was higher a incidence of all-cause mortality after PCI compared with CABG at 10 years of follow-up. Specifically, PCI has higher mortality during the first 5 years and comparable risk beyond 5 years.

Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Left Main Disease With and Without Diabetes: Findings From a Pooled Analysis of 4 Randomized Clinical Trials. Circulation 2024; 149:1328-1338. [PMID: 38465592 DOI: 10.1161/circulationaha.123.065571] [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: 05/12/2023] [Accepted: 02/20/2024] [Indexed: 03/12/2024]
Abstract
BACKGROUND Diabetes may be associated with differential outcomes in patients undergoing left main coronary revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The aim of this study was to investigate outcomes in patients with left main disease with and without diabetes randomized to PCI versus CABG. METHODS Individual patient data were pooled from 4 trials (SYNTAX [Synergy Between PCI With Taxus and Cardiac Surgery], PRECOMBAT [Premier of Randomized Comparison of Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease], NOBLE [Nordic-Baltic-British Left Main Revascularisation Study], and EXCEL [Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization]) that randomized patients with left main disease to PCI or CABG. Patients were considered suitable for either approach. Patients were categorized by diabetes status. Kaplan-Meier event rates, Cox model hazard ratios, and interactions were assessed. RESULTS Among 4393 patients, 1104 (25.1%) had diabetes. Patients with diabetes experienced higher rates of 5-year death (158/1104 [Kaplan-Meier rate, 14.7%] versus 297/3289 [9.3%]; P<0.001), spontaneous myocardial infarction (MI; 67/1104 [6.7%] versus 114/3289 [3.7%]; P<0.001), and repeat revascularization (189/1104 [18.5%] versus 410/3289 [13.2%]; P<0.001). Rates of all-cause mortality did not differ after PCI versus CABG in those with (84/563 [15.3%] versus 74/541 [14.1%]; hazard ratio, 1.11 [95% CI, 0.82-1.52]) or without (155/1634 [9.7%] versus 142/1655 [8.9%]; hazard ratio, 1.08 [95% CI, 0.86-1.36; PintHR=0.87) diabetes. Rates of stroke within 1 year were lower with PCI versus CABG in the entire population, with no heterogeneity based on diabetes status (PintHR=0.51). The 5-year rates of spontaneous MI and repeat coronary revascularization were higher after PCI regardless of diabetes status (spontaneous MI: 45/563 [8.9%] versus 22/541 [4.4%] in diabetes and 82/1634 [5.3%] versus 32/1655 [2.1%] in no diabetes, PintHR=0.47; repeat revascularization: 127/563 [24.5%] versus 62/541 [12.4%] in diabetes and 254/1634 [16.3%] versus 156/1655 [10.1%] in no diabetes, PintHR=0.18). For spontaneous MI and repeat revascularization, there were greater absolute risk differences beyond 1 year in patients with diabetes (4.9% and 9.9%) compared with those without (2.1% and 4.3%; PintARD=0.047 and 0.016). CONCLUSIONS In patients with left main disease considered equally suitable for PCI or CABG and with largely low to intermediate SYNTAX scores, diabetes was associated with higher rates of death and cardiovascular events through 5 years. Compared with CABG, PCI resulted in no difference in the risk of death and a lower risk of early stroke regardless of diabetes status, and a higher risk of spontaneous MI and repeat coronary revascularization, with larger late absolute excess risks in patients with diabetes.

Abstract
BACKGROUND Recently, machine learning algorithms have identified preprocedural γ-glutamyl transferase (GGT) as a significant predictor of long-term mortality after coronary revascularization in the SYNTAX (Synergy Between PCI [Percutaneous Coronary Intervention] With Taxus and Cardiac Surgery) trial. The aim of the present study is to investigate the impact of preprocedural GGT on 10-year all-cause mortality in patients with complex coronary artery disease after revascularization. METHODS AND RESULTS The SYNTAX trial was a randomized trial comparing PCI with coronary artery bypass grafting in 1800 patients with complex coronary artery disease. The present report is a post hoc subanalysis of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) trial, an investigator-driven extended 10-year follow-up of the SYNTAX trial. The association between preprocedural GGT and 10-year all-cause mortality was investigated. The mean values of GGT for men and women were 43.5 (SD, 48.5) and 36.4 (SD, 46.1) U/L, respectively. In multivariable Cox regression models adjusted by traditional risk factors, GGT was an independent predictor for all-cause death at 10-year follow-up, and each SD increase in log-GGT was associated with a 1.24-fold risk of all cause death at 10-year follow-up (95% CI, 1.10-1.40). According to previously reported sex-related GGT thresholds, patients with higher GGT level had a 1.74-fold risk of all-cause death at 10-year follow-up (95% CI, 1.32-2.29) compared with patients with lower GGT level. CONCLUSIONS Preprocedural GGT is an independent predictor of 10-year mortality after coronary revascularization in patients with complex coronary artery disease. In patients with elevated GGT, strong secondary prevention may be required after revascularization and must be studied prospectively. REGISTRATION URL: https://clinicaltrials.gov/study/NCT03417050.

Abstract
Coronary artery bypass grafting (CABG) is one of the foundations of treatment for coronary artery disease. While it has improved substantially since its inception more than 50 years ago, including a rising use of multiple arterial grafting, intraoperative quality assessment is yet to be disseminated as an integral part of the procedure. Herein we review the fundamentals of intraoperative quality assessment in CABG using transient time flow measurement (TTFM) with a focus on its use in arterial grafting.

Abstract
Coronary artery bypass (CABG) has evolved over the decades, supported by scientific evidence from robust studies. The downgrade of the recommendation for CABG in patients with multivessel coronary artery disease proposed by the 2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization and the 2023 ACC/AHA Chronic Coronary Disease Guidelines has brought this discussion to the fore, with prestigious cardiothoracic surgery societies such as AATS and STS not supporting these recommendations. The purpose of this article is to broaden this discussion in light of published studies.

Mechanosensitive super-enhancers regulate genes linked to atherosclerosis in endothelial cells. J Cell Biol 2024; 223:e202211125.

Abstract
Vascular homeostasis and pathophysiology are tightly regulated by mechanical forces generated by hemodynamics. Vascular disorders such as atherosclerotic diseases largely occur at curvatures and bifurcations where disturbed blood flow activates endothelial cells while unidirectional flow at the straight part of vessels promotes endothelial health. Integrated analysis of the endothelial transcriptome, the 3D epigenome, and human genetics systematically identified the SNP-enriched cistrome in vascular endothelium subjected to well-defined atherosclerosis-prone disturbed flow or atherosclerosis-protective unidirectional flow. Our results characterized the endothelial typical- and super-enhancers and underscored the critical regulatory role of flow-sensitive endothelial super-enhancers. CRISPR interference and activation validated the function of a previously unrecognized unidirectional flow-induced super-enhancer that upregulates antioxidant genes NQO1, CYB5B, and WWP2, and a disturbed flow-induced super-enhancer in endothelium which drives prothrombotic genes EDN1 and HIVEP in vascular endothelium. Our results employing multiomics identify the cis-regulatory architecture of the flow-sensitive endothelial epigenome related to atherosclerosis and highlight the regulatory role of super-enhancers in mechanotransduction mechanisms.

Coronary artery bypass grafting versus medical therapy in patients with stable coronary artery disease: An individual patient data pooled meta-analysis of randomized trials. J Thorac Cardiovasc Surg 2024; 167:1022-1032.e14.

Abstract
OBJECTIVES It is unclear whether coronary artery bypass grafting (CABG) improves survival compared with medical therapy (MT) in patients with stable coronary artery disease (CAD). The aim of this analysis was to perform an individual-patient data-pooled meta-analysis of contemporary randomized controlled trials that compared CABG and MT in patients with stable CAD. METHODS A systematic search was performed in January 2021 to identify randomized controlled trials enrolling adult patients with stable CAD, randomized to CABG or MT. Only trials using at least aspirin, beta-blockers, and statins in the MT arm were included. Individual patient data were obtained from all eligible studies and pooled. The primary outcome was all-cause mortality. RESULTS Four trials involving 2523 patients (1261 CABG; 1262 MT) were included with a median follow-up of 5.6 (4.0-9.2) years. CABG was associated with increased risk of all-cause mortality within 30 days (hazard ratio [HR], 4.81; 95% confidence interval [CI], 1.95-11.83) but subsequent reduction in the long-term risk of death (HR, 0.79; 95% CI, 0.69-0.89). As such, the cumulative 10-year mortality rate was lower in patients treated with CABG compared with MT (45.1% vs 51.7%, respectively; odds ratio, 0.70; 95% CI, 0.58-0.85). Age and race were significant treatment effect modifier (interaction P = .003 for both). CONCLUSIONS In patients with stable CAD, initial allocation to CABG was associated with greater periprocedural risk of death but improved long-term survival compared with MT. The survival advantage for CABG became significant after the fourth postoperative year and was particularly pronounced in younger and non-White patients.

Abstract
BACKGROUND Since the initial attempt to adapt the anatomical SYNTAX score (aSS) to coronary computed tomography angiography (CCTA), CCTA imaging technology has evolved, and is currently used as a "decision-maker" for revascularization strategy in complex coronary artery disease (CAD) and has rendered necessary some updating of the aSS to the CCTA modality. OBJECTIVES The aim is to provide updated definitions of the aSS derived from CCTA in patients with complex CAD undergoing CABG. METHODS The modifications of CCTA-aSS are the following; (i) updated definition and detection criteria of total occlusion (TO) in CCTA based on length assessment, (ii) inclusion of scoring points for serial bifurcations located in one single coronary segment. (iii) inclusion of weighing score points for lesions located distal to a TO, not visualized on conventional coronary angiography, but visible in CCTA, (iv) removal of thrombus and bridging collateral items from the weighing score, considering the limited diagnostic capability of CCTA in detecting these specific lesion characteristics. RESULTS the updated CCTA-aSS was tested in a first-in-man study using the sole guidance of CCTA for the planning and performance of bypass surgery in complex CAD (n = 114). An interobserver analysis showed excellent reproducibility (ICC = 0.96, 95 % confidence interval 0.94-0.97). CONCLUSION The updated CCTA-aSS was implemented in a cohort of patients with complex CAD undergoing CABG with the sole guidance of CCTA and FFRCT and the Inter-reproducibility of the analysis of the updated score was found excellent. The prognostic value of the modified CCTA-aSS will be examined in future studies.

Abstract
BACKGROUND The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Five-year outcomes in patients with multivessel coronary artery disease undergoing surgery or percutaneous intervention. Sci Rep 2024; 14:3218. [PMID: 38332036 PMCID: PMC10853195 DOI: 10.1038/s41598-024-53905-4] [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: 11/18/2023] [Accepted: 02/06/2024] [Indexed: 02/10/2024] Open
Abstract
The outcomes from real-life clinical studies regarding the optimal revascularization strategy in patients with multivessel coronary artery disease (MVD) are still poorly investigated. In this retrospective study we assessed 5-year outcomes: primary, secondary endpoints and quality of life of 1035 individuals with severe coronary artery disease (CAD) treated either with coronary artery bypass grafting (CABG)-356 patients or percutaneous coronary intervention (PCI)-679 patients according to the recommendation of a local Heart Team (HT). At 5 years no significant difference in overall mortality and rates of myocardial infarctions (MI) were observed between CABG and PCI cohorts (11.0% vs. 13.4% for PCI, P = 0.27 and 9.6% vs. 12.8% for PCI, P = 0.12, respectively). The incidence of major adverse cardiac and cerebrovascular events (MACCE), mainly driven by increased rates of repeat revascularization (RR) were higher in PCI-cohort than in CABG-group (56.1% vs. 40.4%, P < 0.01 and 26.8% vs. 12.6%, P < 0.01, respectively), while CABG-patients experienced stroke more often (7.3% vs. 3.1% for PCI, P < 0.01). In real-life practice with long-term follow-up, none of the two revascularization modalities implemented following HT decisions showed overwhelming superiority: occurrence of death and MI were similar, rates of RR favoured CABG, while incidence of strokes advocated PCI.

Abstract
Little is known regarding the long-term (> 10 years) outcomes and risk factors of total arterial coronary artery bypass grafting (CABG). This study evaluated the long-term outcomes and risk factors for all-cause mortality and major adverse cardiac and cerebrovascular events (MACCEs) following total arterial on-pump CABG (ONCAB) or off-pump CABG (OPCAB) with complete revascularization. This retrospective cohort analysis enrolled patients with stable angina who underwent total arterial CABG with complete revascularization in our institute between July 2000 and June 2019. The endpoints were all-cause mortality and MACCE incidence, including a comparison between OPCAB and ONCAB. Long-term (10-year) outcomes were analyzed using propensity score-matched pairs, and risk factors were evaluated using univariate and multivariate analyses. Overall, 401 patients who underwent primary total arterial CABG were classified into the OPCAB (n = 269) and ONCAB (n = 132) groups. Using propensity score matching (PSM), 88 patients who underwent OPCAB were matched with 88 patients who underwent ONCAB. The mean follow-up period was 7.9 ± 6.3 years. No significant difference in all-cause mortality (hazard ratio, 1.04; 95% confidence interval, 0.53-2.04; p = 0.9138) and MACCE incidence (hazard ratio, 1.06; 95% confidence interval, 0.68-1.65; p = 0.7901) was observed between the two groups. Renal failure requiring dialysis was a significant risk factor for mortality (p < 0.0001) and MACCEs (p = 0.0003). Long-term outcomes of total arterial OPCAB and ONCAB with complete revascularization showed similar findings using PSM. Renal failure requiring dialysis was a significant risk factor for mortality and morbidity.Journal standard instruction requires an unstructured abstract; hence the headings provided in abstract were deleted.

Abstract
BACKGROUND Significant left main coronary artery (LMCA) disease is prevalent in 7% of patients undergoing angiography. Limited data exists on the impact of double scrubbing in LMCA PCI. We sought to assess periprocedural outcomes in two-operator LMCA percutaneous coronary intervention (PCI). METHODS Using data from the Polish National Registry of PCI (ORPKI), we collected data on 28,745 patients undergoing LMCA PCI from 154 centers. Patients were divided into two groups based on the number of operators performing PCI (one vs. two operators). RESULTS LMCA PCI was performed by a single operator in 86% of the cases and by two operators in 14% of cases. Patients treated by two operators had a greater comorbidity burden including diabetes mellitus, arterial hypertension, previous myocardial infarction, and previous revascularization. In addition, these were more likely to be treated in high-volume centers, by operators with higher volume of LMCA PCIs. The risk of periprocedural death (2.37% vs. 2.44%; P=0.78), as well as cardiac arrest, coronary artery perforation, no-reflow, and puncture site bleeding was comparable between the two groups. On multivariable analysis, we found that a two-operator strategy was an independent predictor of periprocedural death, with this effect being much more profound in an elective setting (OR=5.13 [1.37-19.26]; P=0.015), compared to an urgent (ACS) setting (OR=1.32 [1.00-1.73]; P=0.047). CONCLUSIONS Our study suggests that a two-operator approach is not necessarily routinely recommended for LMCA interventions, although it can be considered for more complex cases.

Thirteen Years of Impactful, Minimally Invasive Coronary Surgery: Short- and Long-Term Results for Single and Multi-Vessel Disease. J Clin Med 2024; 13:761. [PMID: 38337455 PMCID: PMC10856352 DOI: 10.3390/jcm13030761] [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: 12/16/2023] [Revised: 01/18/2024] [Accepted: 01/26/2024] [Indexed: 02/12/2024] Open
Abstract
OBJECTIVES Minimally invasive coronary surgery (MICS) via lateral thoracotomy is a less invasive alternative to the traditional median full sternotomy approach for coronary surgery. This study investigates its effectiveness for short- and long-term revascularization in cases of single and multi-vessel diseases. METHODS A thorough examination was performed on the databases of two cardiac surgery programs, focusing on patients who underwent minimally invasive coronary bypass grafting procedures between 2010 and 2023. The study involved patients who underwent either minimally invasive direct coronary artery bypass grafting (MIDCAB) for the revascularization of left anterior descending (LAD) artery stenosis or minimally invasive multi-vessel coronary artery bypass grafting (MICSCABG). Our assessment criteria included in-hospital mortality, long-term mortality, and freedom from reoperations due to failed aortocoronary bypass grafts post-surgery. Additionally, we evaluated significant in-hospital complications as secondary endpoints. RESULTS A total of 315 consecutive patients were identified between 2010 and 2023 (MIDCAB 271 vs. MICSCABG 44). Conversion to median sternotomy (MS) occurred in eight patients (2.5%). The 30-day all-cause mortality was 1.3% (n = 4). Postoperative AF was the most common complication postoperatively (n = 26, 8.5%). Five patients were reoperated for bleeding (1.6%), and myocardial infarction (MI) happened in four patients (1.3%). The mean follow-up time was six years (±4 years). All-cause mortality was 10.3% (n = 30), with only five (1.7%) patients having a confirmed cardiac cause. The reoperation rate due to graft failure or the progression of aortocoronary disease was 1.4% (n = 4). CONCLUSIONS Despite the complexity of the MICS approach, the results of our study support the safety and effectiveness of this procedure with low rates of mortality, morbidity, and conversion for both single and multi-vessel bypass surgeries. These results underscore further the necessity to implement such programs to benefit patients.

Abstract
INTRODUCTION Conventional vein grafts have a high risk of thrombosis and early atherosclerosis. Percutaneous coronary intervention (PCI) in conventional vein grafts is associated with a higher incidence of late adverse cardiac events. The aim of this study was to evaluate the long-term results after PCI in saphenous vein grafts (SVG) harvested with the no-touch technique compared to the conventional technique. METHODS This was a single-center, retrospective, cohort study, based on data from the Swedeheart register. The inclusion criterion was individuals who underwent CABG using different vein graft techniques between January 1992 and July 2020, and who required a PCI in SVGs between January 2006 and July 2020. The primary end point was long-term in-stent restenosis. The secondary endpoints were long-term major adverse cardiac events (MACE) and 1-year re-hospitalization rates. The associations between the graft types and the endpoints were evaluated using the Fine and Gray competing-risk regression analysis. RESULTS The study included 346 individuals (67 no-touch, 279 conventional). The mean clinical follow-up time was 6.4 years with a standard deviation of 3.7 years. The long-term in-stent restenosis rate for the no-touch grafts was 3.2% compared to 18.7% for the conventional grafts (p < .01), with a subdistribution hazard ratio (SHR) of 0.16 (p = .010). The long-term MACE rate was 27.0% in the no-touch group and 48.3% in the conventional group (p < .01) with a SHR of 0.53 (p = .017). The short-term results were similar in both groups. CONCLUSIONS Percutaneous coronary intervention in a no-touch vein graft was associated with statistically significantly fewer in-stent restenoses and MACE at long-term follow-up compared to a conventional SVG.

Abstract
Patients with left main coronary artery disease (LMCAD) with a high SYNTAX score (SS) were excluded from randomized studies that comparing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). We sought to compare PCI and CABG in the real-world practice and investigate the impact of SS I, SS II, and SS II 2020 on clinical outcomes. In total, 292 Patients with LMCAD (173 PCI, 119 CABG) treated between 2017 and 2021 were enrolled. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, stroke, or myocardial infarction (MI). The mean SS I was high in both groups (PCI vs. CABG: 31.64 ± 11.45 vs. 32.62 ± 11.75, p = 0.660). The primary outcome occurred in 28 patients (16.2%) in the PCI group and in 19 patients (16.0%) in the CABG group without significant difference [adjusted hazard ratio, 95% CI = 0.98 (0.51-1.90), p = 0.97] over the follow-up period (26.9 ± 17.7 months). No significant difference was observed in all-cause mortality (11.6% vs. 11.8%, p = 0.93) or stroke rates (3.5% vs. 5.0%, p = 0.51) between groups. However, PCI was associated with higher MI (4.6% vs. 0.8%, p < 0.05) and revascularization rates (26% vs. 5.9%, p < 0.001). Prognostic value of the SS I, SS II and SS II 2020 on the primary outcome was not relevant in the PCI group. Among patients with LMCAD, PCI and CABG did not significantly differ in the composite endpoint of all-cause death, stroke, and MI. These results support the potential expansion of PCI indications in LMCAD management for whom are ineligible for CABG with complex coronary artery disease.

Abstract
BACKGROUNDS The impact of reduced left ventricular ejection fraction (LVEF) on very long-term prognosis following percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) has been debated. The aim of this study was to investigate the impact of LVEF at baseline on 10-year mortality in the SYNTAX trial. METHODS Patients (n = 1800) were categorized into three sub-groups: reduced (rEF ≤ 40 %), mildly reduced (mrEF 41-49 %), and preserved LVEF (pEF ≥ 50 %). The SYNTAX score 2020 (SS-2020) was applied in patients with LVEF<50 % and ≥ 50 %. RESULTS Ten-year mortalities were 44.0 %, 31.8 %, and 22.6 % (P < 0.001) in patients with rEF (n = 168), mrEF (n = 179), and pEF (n = 1453). Although no significant differences were observed, the mortality with PCI was higher than with CABG in patients with rEF (52.9 % vs 39.6 %, P = 0.054) and mrEF (36.0 % vs. 28.6 %, P = 0.273), and comparable in pEF (23.9 % vs. 22.2 %, P = 0.275). Calibration and discrimination of the SS-2020 in patients with LVEF<50 % were poor, whilst they were reasonable in those with LVEF≥50 %. The proportion of patients eligible for PCI who had a predicted equipoise in mortality with CABG was estimated to be 57.5 % in patients with LVEF≥50 %. CABG was safer than PCI in 62.2 % of patients with LVEF<50 %. CONCLUSIONS Reduced LVEF was associated with an increased risk of 10-year mortality in patients revascularized either surgically or percutaneously. Compared to PCI, CABG was safe revascularization in patients with LVEF≤40 %. In patients with LVEF≥50 % individualized 10-year all-cause mortality predicted by SS-2020 was helpful in decision-making whilst the predictivity in patients with LVEF<50 % was poor.

Abstract
Coronary artery bypass graft (CABG) surgery remains a pivotal cornerstone, offering established symptomatic alleviation and prognostic advantages for patients grappling with complex multivessel and left main coronary artery diseases. Despite the lucid guidance laid out by contemporary guidelines regarding the choice between CABG and percutaneous coronary intervention (PCI), a notable hesitation persists among certain patients, characterized by psychological reservations, knowledge gaps, or individual beliefs that sway their inclination toward surgical intervention. This comprehensive review critically synthesizes the prevailing guidelines, modern practices, and outcomes pertaining to CABG surgery, delving into an array of techniques and advancements poised to enhance both short-term and enduring surgical outcomes. The exploration encompasses advances in on-pump and off-pump procedures, conduit selection strategies encompassing the bilateral utilization of internal mammary artery and radial artery conduits, meticulous graft evaluation methodologies, and the panorama of minimally invasive approaches, including those assisted by robotic technology. Furthermore, the review navigates the terrain of hybrid coronary revascularization, shedding light on the pivotal roles of shared decision-making and the heart team in shaping treatment pathways. As a comprehensive compendium, this review not only navigates the intricate landscape of CABG surgery but also aligns it with contemporary practices, envisioning its trajectory within the evolving currents of healthcare dynamics.

Abstract
OBJECTIVE To compare outcomes in women undergoing percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery. DESIGN This retrospective, propensity-score matched cohort study from the New York State cardiac registry (2012-2018) included all women with multivessel coronary artery disease undergoing PCI with everolimus-eluting stents (EES) and CABG surgery. The primary outcome was all-cause mortality. The key secondary outcome was major adverse cardiac events, defined as the composite of all-cause mortality, myocardial infarction, and stroke. RESULTS PCI with EES was associated with a higher 6-year risk of mortality (25.75% vs 23.57%; adjusted hazard ratio [AHR], 1.29; 95% confidence interval [CI], 1.14-1.45). PCI also was associated with a higher rate of the composite outcome of death, myocardial infarction, and stroke (36.58% vs 32.89%; AHR, 1.28; 95% CI, 1.17-1.41), as well as myocardial infarction (14.94% vs 9.12%; AHR, 1.84; 95% CI, 1.56-2.17), but not stroke (7.07% vs 7.62%; AHR, 0.83; 95% CI, 0.67-1.03). Repeat revascularization rates also were higher for women undergoing PCI (21.53% vs 11.57%; AHR, 1.88; 95% CI, 1.63-2.17). There was no difference in mortality between the 2 interventions when PCI patients received complete revascularization or had noncomplex lesions and for women without diabetes. CONCLUSIONS For women with multivessel coronary artery disease, CABG surgery is associated with lower 6-year mortality, myocardial infarction, and repeat revascularization rates compared to PCI with EES.

Abstract
Current guidelines give priority to surgical treatment of carotid artery stenosis (CAS) before coronary artery bypass grafting (CABG), especially in symptomatic patients. Carotid artery stenting is an alternative treatment for narrowing of the carotid arteries. This study sought to demonstrate the role of severe CAS in predicting stroke after CABG and assess the efficacy of carotid artery stenting in preventing postoperative stroke in a Chinese cohort. From 2015 to 2021, 1799 consecutive patients undergoing isolated CABG surgery were retrospectively recruited in a Chinese cohort. The predictive value of severe CAS in postoperative stroke and carotid stenting in preventing postoperative stroke was statistically analyzed. The incidence of postoperative stroke was 1.67%. The incidence of CAS with stenosis ≥ 50% and ≥ 70% was 19.2% and 6.9%. After propensity matching, the incidence of stroke was 8.0% in the severe CAS group and 0% in the non-severe CAS group. We successfully established an optimal predictive nomogram for predicting severe CAS in patients undergoing CABG. Carotid artery stenting was found ineffective in preventing postoperative stroke. The present study provides the incidence of CAS and postoperative stroke in a Chinese cohort, identifies severe CAS as an independent risk factor for postoperative stroke after CABG, constructs a nomogram predicting the incidence of severe CAS, and evaluates the effectiveness of carotid artery stenting in preventing postoperative stroke after CABG.

Abstract
BACKGROUND Interpretation of recent alterations to the guideline priority of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for multivessel disease contests historical data and practice. To reevaluate contemporary outcomes, a large contemporary analysis was conducted comparing CABG with multivessel PCI among Medicare beneficiaries. METHODS The United States Centers for Medicare and Medicaid Services database was evaluated all beneficiaries with acute coronary syndrome undergoing isolated CABG or multivessel PCI (2018-2020). Risk adjustment was performed using multilevel regression analysis, Cox proportional hazards time to event models, and inverse probability of treatment weighting propensity scores. RESULTS A total of 104,127 beneficiaries were identified undergoing CABG (n = 51,389) or multivessel PCI (n = 52,738). Before risk adjustment, compared with PCI, CABG patients were associated with younger age (72.9 vs 75.2 years, P < .001), higher Elixhauser Comorbidity Index (5.0 vs 4.2, P < .001), more diabetes (48.5% vs 42.2%, P < .001), higher cost ($54,154 vs $33,484, P < .001), and longer length of stay (11.9 vs 5.8 days, P < .001). After inverse probability of treatment weighting propensity score adjustment, compared with PCI, CABG was associated with lower hospital mortality (odds ratio, 0.74; P < .001), fewer hospital readmissions at 3 years (odds ratio, 0.85; P < .001), fewer coronary reinterventions (hazard ratio, 0.37; P < .001), and improved 3-year survival (hazard ratio, 0.51; P < .001). CONCLUSIONS Contemporary real-world data from Medicare patients with multivessel disease reveal that CABG outcomes were superior to PCI, providing important longitudinal data to guide patient care and policy development.

[PMID: 37453928 PMCID: PMC10351454 DOI: 10.1080/07853890.2023.2232369] [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: 05/03/2023] [Revised: 06/15/2023] [Accepted: 06/26/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Bile acids play crucial roles in various metabolisms, as well as Lactobacillus in the intestine. But studies on their roles in acute coronary syndrome (ACS) are still insufficient. The aim of this study was to investigate their role and potential association with the severity of coronary lesions and the prognosis of ACS. METHODS Three hundred and sixty ACS patients were selected. Detection of gut Lactobacillus levels was done through 16S rDNA sequence analysis. Evaluation of the extent of lesions was done using the SYNTAX (SS) score. Mediation analysis was used to assess the relationship between serum total bile acid (TBA), Lactobacillus, atherosclerotic lesions and prognosis of ACS. RESULTS Logistic regressive analysis disclosed that serum TBA and Lactobacillus were independent predictors of coronary lesions (high vs. low SS: serum TBA adjusted odds ratio (aOR) = 0.8, 95% confidence interval (CI): 0.6-0.9, p < .01; Lactobacillus: aOR = 0.9, 95% CI: 0.9-1.0, p = .03). According to multivariate Cox regression analysis, they were negatively correlated with the overall risk of all-cause death (serum TBA: adjusted hazard ratio (aHR) = 0.1, 95% CI: 0.0-0.6, p = .02; Lactobacillus: aHR = 0.6, 95% CI: 0.4-0.9, p = .01), especially in acute myocardial infarction (AMI) but not in unstable angina pectoris (UAP). Ulteriorly, mediation analysis showed that serum TBA played an important role as a mediation effect in the following aspects: Lactobacillus (17.0%, p < .05) → SS association (per 1 standard deviation (SD) increase), Lactobacillus (43.0%, p < .05) → all-cause death (per 1 SD increase) and Lactobacillus (45.4%, p < .05) → cardiac death (per 1 SD increase). CONCLUSIONS The lower serum TBA and Lactobacillus level in ACS patients, especially in AMI, was independently linked to the risk of coronary lesions, all-cause death and cardiac death. In addition, according to our mediation model, serum TBA served as a partial intermediate in predicting coronary lesions and the risk of death by Lactobacillus, which is paramount to further exploring the mechanism of Lactobacillus and bile acids in ACS.KEY MESSAGESLower level of serum total bile acid (TBA) was highly associated with the severity of coronary lesions, myocardial damage, inflammation and gut Lactobacillus in acute coronary syndrome (ACS) patients, especially in acute myocardial infarction (AMI).Lower level of serum TBA was highly associated with mortality (including all-cause death and cardiac death) in patients with ACS, especially with AMI.Serum TBA had a partial mediating effect rather than regulating effect between gut Lactobacillus and coronary lesions and prognosis of ACS.

Abstract
Percutaneous coronary intervention (PCI) has increasingly become the main treatment for coronary artery disease. The procedure requires high experienced skills and dexterous manipulations. However, there are few techniques to model PCI skill so far. In this study, a learning framework with local and ensemble learning is proposed to learn skill characteristics of different skill-level subjects from their PCI manipulations. Ten interventional cardiologists (four experts and six novices) were recruited to deliver a medical guidewire to two target arteries on a porcine model for in vivo studies. Simultaneously, translation and twist manipulations of thumb, forefinger, and wrist are acquired with electromagnetic (EM) and fiber-optic bend (FOB) sensors, respectively. These behavior data are then processed with wavelet packet decomposition (WPD) under 1-10 levels for feature extraction. The feature vectors are further fed into three candidate individual classifiers in the local learning layer. Furthermore, the local learning results from different manipulation behaviors are fused in the ensemble learning layer with three rule-based ensemble learning algorithms. In subject-dependent skill characteristics learning, the ensemble learning can achieve 100% accuracy, significantly outperforming the best local result (90%). Furthermore, ensemble learning can also maintain 73% accuracy in subject-independent schemes. These promising results demonstrate the great potential of the proposed method to facilitate skill learning in surgical robotics and skill assessment in clinical practice.

Selective ensemble methods for deep learning segmentation of major vessels in invasive coronary angiography. Med Phys 2023; 50:7822-7839. [PMID: 37310802 DOI: 10.1002/mp.16554] [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: 07/10/2022] [Revised: 03/29/2023] [Accepted: 05/26/2023] [Indexed: 06/15/2023] Open
Abstract
BACKGROUND Invasive coronary angiography (ICA) is a primary imaging modality that visualizes the lumen area of coronary arteries for diagnosis and interventional guidance. In the current practice of quantitative coronary analysis (QCA), semi-automatic segmentation tools require labor-intensive and time-consuming manual correction, limiting their application in the catheterization room. PURPOSE This study aims to propose rank-based selective ensemble methods that improve the segmentation performance and reduce morphological errors that limit fully automated quantification of coronary artery using deep-learning segmentation of ICA. METHODS Two selective ensemble methods proposed in this work integrated the weighted ensemble approach with per-image quality estimation. The segmentation outcomes from five base models with different loss functions were ranked either by mask morphology or estimated dice similarity coefficient (DSC). The final output was determined by imposing different weights according to the ranks. The ranking criteria based on mask morphology were formulated from empirical insight to avoid frequent types of segmentation errors (MSEN), while the estimation of DSCs was performed by comparing the pseudo-ground truth generated from a meta-learner (ESEN). Five-fold cross-validation was performed with the internal dataset of 7426 coronary angiograms from 2924 patients, and prediction model was externally validated with 556 images of 226 patients. RESULTS The selective ensemble methods improved the segmentation performance with DSCs up to 93.07% and provided a better delineation of coronary lesion with local DSCs of up to 93.93%, outperforming all individual models. Proposed methods also minimized the chances of mask disconnection in the most narrowed regions to 2.10%. The robustness of the proposed methods was also evident in the external validation. Inference time for major vessel segmentation was approximately one-sixth of a second. CONCLUSION Proposed methods successfully reduced morphological errors in the predicted masks and were able to enhance the robustness of the automatic segmentation. The results suggest better applicability of real-time QCA-based diagnostic methods in routine clinical settings.

Off-pump vs. on-pump bypass surgery grafting in diabetic patients with three-vessel disease: a propensity score matching study. Front Cardiovasc Med 2023; 10:1249881. [PMID: 38099225 PMCID: PMC10719841 DOI: 10.3389/fcvm.2023.1249881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 11/14/2023] [Indexed: 12/17/2023] Open
Abstract
Background Controversy exists regarding the advantages and risks of off-pump vs. on-pump coronary artery bypass grafting (CABG) for patients with diabetes. We therefore compare the early clinical outcomes of off-pump vs. on-pump procedures for diabetic patients with three-vessel disease. Materials and methods We conducted a retrospective analysis of clinical data obtained from 548 diabetic patients with three-vessel coronary artery disease who underwent isolated CABG between January 2016 and June 2020. To adjust the differences of baseline characteristics between the off-pump CABG (OPCAB) and on-pump CABG (ONCAB) groups, propensity score matching (PSM) was used. Following 1:1 matching, we selected 187 pairs of patients for further comparison of outcomes within the first 30 days after surgery. Results The preoperative characteristics of the patients between the two groups were clinically comparable after PSM. The OPCAB group exhibited a significantly higher incidence of incomplete revascularization (27.3% vs. 14.4%; P = 0.002) compared with the ONCAB group. No differences were seen in mortality within 30 days between the matched groups (1.1% vs. 3.7%; P = 0.174). Notably, the OPCAB group had a lower risk of respiratory failure or infection (2.1% vs. 7.0%; P = 0.025), less postoperative stroke (1.1% vs. 4.8%; P = 0.032), and reduced postoperative ventilator assistance time (35.8 ± 33.7 vs. 50.9 ± 64.8; P = 0.005). Conclusion OPCAB in diabetic patients with three-vessel disease is a safe procedure with reduced early stroke and respiratory complications and similar mortality rate, myocardial infarction, and renal failure requiring dialysis to conventional on-pump revascularization.

The association between fibrinogen levels and severity of coronary artery disease and long-term prognosis following percutaneous coronary intervention in patients with type 2 diabetes mellitus. Front Endocrinol (Lausanne) 2023; 14:1287855. [PMID: 38093962 PMCID: PMC10716187 DOI: 10.3389/fendo.2023.1287855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 11/07/2023] [Indexed: 12/18/2023] Open
Abstract
Background Fibrinogen is a potential risk factor for the prognosis of CAD and is associated with the complexity of CAD. There is limited research specifically investigating the predictive role of fibrinogen in determining the severity of CAD among patients with T2DM, as well as its impact on the prognosis following PCI. Methods The study included 675 T2DM patients who underwent PCI at the Third People's Hospital of Chengdu between April 27, 2018, and February 5, 2021, with 540 of them remaining after exclusions. The complexity of CAD was assessed using the SYNTAX score. The primary endpoint of the study was the incidence of MACCEs. Results After adjusting for multiple confounding factors, fibrinogen remained a significant independent risk factor for mid/high SYNTAX scores (SYNTAX score > 22, OR 1.184, 95% CI 1.022-1.373, P = 0.025). Additionally, a dose-response relationship between fibrinogen and the risk of complicated CAD was observed (SYNTAX score > 22; nonlinear P = 0.0043). The area under the receiver operating characteristic curve(AUROC) of fibrinogen for predicting mid/high SYNTAX score was 0.610 (95% CI 0.567-0.651, P = 0.0002). The high fibrinogen group (fibrinogen > 3.79 g/L) had a higher incidence of calcified lesions and an elevated trend of more multivessel disease and chronic total occlusion. A total of 116 patients (21.5%) experienced MACCEs during the median follow-up time of 18.5 months. After adjustment, multivariate Cox regression analysis confirmed that fibrinogen (HR, 1.138; 95% CI 1.010-1.284, P = 0.034) remained a significant independent risk factor for MACCEs. The AUROC of fibrinogen for predicting MACCEs was 0.609 (95% CI 0.566-0.650, P = 0.0002). Individuals with high fibrinogen levels (fibrinogen > 4.28 g/L) had a higher incidence of acute myocardial infarction (P < 0.001), MACCEs (P < 0.001), all-cause death (P < 0.001), stroke (P = 0.030), and cardiac death (P = 0.002). Kaplan-Meier analysis revealed a higher incidence of MACCEs in the high fibrinogen group (Log-Rank test: P < 0.001). Conclusions Elevated fibrinogen levels were associated with increased coronary anatomical complexity (as quantified by the SYNTAX score) and a higher incidence of MACCEs after PCI in patients with T2DM.

Abstract
BACKGROUND In patients with 3-vessel coronary artery disease (CAD) and/or left main CAD, individual risk prediction plays a key role in deciding between percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). OBJECTIVES The aim of this study was to assess whether these individualized revascularization decisions can be improved by applying machine learning (ML) algorithms and integrating clinical, biological, and anatomical factors. METHODS In the SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery) study, ML algorithms (Lasso regression, gradient boosting) were used to develop a prognostic index for 5-year death, which was combined, in the second stage, with assigned treatment (PCI or CABG) and prespecified effect-modifiers: disease type (3-vessel or left main CAD) and anatomical SYNTAX score. The model's discriminative ability to predict the risk of 5-year death and treatment benefit between PCI and CABG was cross-validated in the SYNTAX trial (n = 1,800) and externally validated in the CREDO-Kyoto (Coronary REvascularization Demonstrating Outcome Study in Kyoto) registry (n = 7,362), and then compared with the original SYNTAX score II 2020 (SSII-2020). RESULTS The hybrid gradient boosting model performed best for predicting 5-year all-cause death with C-indexes of 0.78 (95% CI: 0.75-0.81) in cross-validation and 0.77 (95% CI: 0.76-0.79) in external validation. The ML models discriminated 5-year mortality better than the SSII-2020 in the external validation cohort and identified heterogeneity in the treatment benefit of CABG vs PCI. CONCLUSIONS An ML-based approach for identifying individuals who benefit from CABG or PCI is feasible and effective. Implementation of this model in health care systems-trained to collect large numbers of parameters-may harmonize decision making globally.

Abstract
Background and Objectives: Surgical revascularisation of patients with atherosclerosis of the ascending aorta remains a challenge. Different surgical strategies have been described in coronary surgical patients to offer alternative revascularisation strategies other than the conventional surgical revascularisation in patients unsuitable for it. The aim of this study is to compare the real-world outcomes between two groups of patients who underwent off-pump surgery (left internal mammary artery graft to the left anterior descending artery) or a hybrid with a percutaneous revascularisation procedure at a later stage. Materials and Methods: This is a single-centre retrospective observational study. Between the years 2010 and 2021, 91/6863 patients (1.33%) were diagnosed with severe atherosclerosis of the ascending aorta. All the patients were treated with off-pump revascularisation (91 patients), and the cardiologist would decide at a later stage whether the rest of the vessels would be treated with percutaneous revascularisation (25 patients). Results: There was no statistical difference in the various preoperative characteristics, except for coronary artery left main disease (30.30% vs. 64%; p = 0.0043). The two groups had no statistical differences in the perioperative characteristics and postoperative complications. The 1-, 5-, and 10-year mortality rates in the two groups were 6.1% vs. 0%, 59% vs. 80%, and 93.9% vs. 100%, respectively (off-pump vs. hybrid with percutaneous revascularisation procedure, p = 0.1958). Conclusions: Both strategies have high long-term comparable mortality. The off-pump surgery and the HCR procedure at a later stage may be solutions for these high-risk patients, but the target treatment should be complete HCR revascularisation during the index hospitalization.

Abstract
OBJECTIVES The ISCHEMIA trial is a landmark study that has been the subject of heated debate within the cardiovascular community. In this analysis of the ISCHEMIA trial, we aim to set the record straight on the benefits of coronary artery bypass grafting (CABG) and the misinterpretation of this landmark trial. We sought to clarify and reorient this misinterpretation. METHODS We herein analyse the ISCHEMIA trial in detail and describe how its misinterpretation has led to an erroneous guideline recommendation downgrading for prognosis-altering surgical therapy in these at-risk patients. RESULTS The interim ISCHEMIA trial findings align with previous evidence where CABG reduces the long-term risks of myocardial infarction and mortality in advanced coronary artery disease. The trial outcomes of a significantly lower rate of cardiovascular mortality and a higher rate of non-cardiovascular mortality with the invasive strategy are explained according to landmark evidence. CONCLUSIONS The ISCHEMIA trial findings are aligned with previous evidence and should not be used to downgrade recommendations in recent guidelines for the indisputable benefits of CABG.

2022 Joint ESC/EACTS review of the 2018 guideline recommendations on the revascularization of left main coronary artery disease in patients at low surgical risk and anatomy suitable for PCI or CABG. Eur Heart J 2023; 44:4310-4320.

Abstract
In October 2021, the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) jointly agreed to establish a Task Force (TF) to review recommendations of the 2018 ESC/EACTS Guidelines on myocardial revascularization as they apply to patients with left main (LM) disease with low-to-intermediate SYNTAX score (0-32). This followed the withdrawal of support by the EACTS in 2019 for the recommendations about the management of LM disease of the previous guideline. The TF was asked to review all new relevant data since the 2018 guidelines including updated aggregated data from the four randomized trials comparing percutaneous coronary intervention (PCI) with drug-eluting stents vs. coronary artery bypass grafting (CABG) in patients with LM disease. This document represents a summary of the work of the TF; suggested updated recommendations for the choice of revascularization modality in patients undergoing myocardial revascularization for LM disease are included. In stable patients with an indication for revascularization for LM disease, with coronary anatomy suitable for both procedures and a low predicted surgical mortality, the TF concludes that both treatment options are clinically reasonable based on patient preference, available expertise, and local operator volumes. The suggested recommendations for revascularization with CABG are Class I, Level of Evidence A. The recommendations for PCI are Class IIa, Level of Evidence A. The TF recognized several important gaps in knowledge related to revascularization in patients with LM disease and recognizes that aggregated data from the four randomized trials were still only large enough to exclude large differences in mortality.

Abstract
OBJECTIVES This study describes coronary revascularization strategies used by sex and age in the USA. METHODS A sex-stratified cohort study from the National Inpatient Sample from the Agency for Healthcare Research and Quality (USA) including patients admitted for coronary revascularization with primary or secondary diagnoses of chronic coronary syndrome or non-ST elevation myocardial infarction who underwent ≥3-vessel coronary artery bypass grafting or percutaneous coronary intervention from January 2019 to December 2020. The primary outcome was the use rate of coronary artery bypass grafting or multivessel percutaneous coronary intervention. Prespecified subgroups included age and non-ST elevation myocardial infarction. RESULTS Among 121 150 patients (21.7% women), there were no sex differences in age (women: 66.6 [66.5-66.7], men: 67.6 [67.5-67.7], standardized mean difference: 0.1) or non-ST elevation myocardial infarction incidence (women: 37.4%, men: 45.7%, standardized mean difference: 0.17). The majority of women (74.2%) and men (84.9%) underwent bypass grafting, which was unaffected by age, race or non-ST elevation myocardial infarction. Women were less likely to undergo bypass grafting than percutaneous intervention (adjusted odds ratio 0.49, 95% confidence interval 0.44-0.54; P < 0.001) and a disparity most pronounced in patients >80 years old (adjusted odds ratio 0.31, 95% confidence interval 0.22-0.45; P < 0.001). CONCLUSIONS Most patients with multivessel coronary artery disease needing revascularization undergo bypass grafting, irrespective of sex, age or clinical presentation. The sex disparity in the use of bypass grafting is mostly seen among patients >80 years old.

Percutaneous Coronary Intervention vs. Coronary Artery Bypass Grafting in Left Main Coronary Artery Disease: An Updated Systematic Review and Meta-Analysis. Cureus 2023; 15:e48297.

Abstract
Recently, both US and European guidelines have predominantly recommended coronary artery bypass grafting (CABG) as the preferred revascularisation method. However, emerging data have raised the possibility of percutaneous coronary intervention (PCI) being a viable and effective alternative. This meta-analysis sought to evaluate the latest insights from major clinical trials to ascertain whether PCI could be as effective as CABG in treating left main coronary artery (LMCA) disease. To achieve this, a comprehensive systematic search was conducted across databases, including Medline (via PubMed), Embase, Cochrane, and clinicaltrials.gov. The search spanned from the inception of these databases to August 20, 2022, and exclusively focused on randomized controlled trials (RCTs). Employing the random effects model, selected studies underwent rigorous analysis. The study outcomes encompassed a spectrum of factors such as all-cause mortality, major adverse cerebrovascular and cardiovascular events (MACCE), myocardial infarction (MI), stroke, and revascularisation procedures. The observation periods of interest included the 30-day mark, 1 year, 5 years, and 10 years. The analysis integrated six RCTs, revealing noteworthy patterns. In terms of all-cause mortality, PCI demonstrated non-inferiority to CABG across all observed time frames: 30 days (OR 0.6), 1 year (OR 0.77), 5 years (OR 1.41), and 10 years (OR 1.08). Analysis of MACCE outcomes favored PCI at 30 days and CABG at 5 years. The utilisation of the original five-year EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularisation) trial definition for MI highlighted higher MI rates for PCI compared to CABG (OR 1.66, P < 0.05). Intriguingly, when the subsequently released EXCEL data, aligned with the third universal MI definition, was incorporated, the five-year data consistently leaned towards CABG. Specifically, the PCI group exhibited 7.5% MI rates in contrast to the 3.6% in the CABG cohort (OR 2.19, P < 0.001). Concerning stroke, PCI proved advantageous at 30 days and 1 year while exhibiting no significant disparity at 5 and 10 years. Revascularisation procedures favoured CABG at one and five years, with comparability at the remaining time points. In summation, the outcomes of this comprehensive meta-analysis suggest that PCI could serve as a feasible alternative to CABG in the context of uncomplicated LMCA disease. It's worth noting that CABG might still hold an advantage for complex lesions.

HbA1c control in type 2 diabetes mellitus patients with coronary artery disease: a retrospective study in a tertiary hospital in South Africa. FRONTIERS IN CLINICAL DIABETES AND HEALTHCARE 2023; 4:1258792. [PMID: 38028982 PMCID: PMC10645148 DOI: 10.3389/fcdhc.2023.1258792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 10/16/2023] [Indexed: 12/01/2023]
Abstract
Background Type 2 diabetes mellitus (T2DM) patients with coronary artery disease (CAD) have an increased risk of recurrent cardiovascular events. These patients require optimal glucose control to prevent the progression of atherosclerotic cardiovascular disease (ASCVD). Contemporary guidelines recommend an HbA1c ≤7% to mitigate this risk. The aim of this study was to evaluate HbA1c control in T2DM patients with angiographically proven ASCVD. Methods We conducted a cross-sectional, retrospective study on consecutive T2DM patients with acute and chronic coronary syndromes managed in a tertiary academic hospital in South Africa. Glycaemic control was assessed by evaluating the glycated haemoglobin (HbA1c) level measured at index presentation with acute and chronic coronary syndromes and during the most recent follow-up visit. Results The study population comprised 262 T2DM patients with a mean age of 61.3 ± 10.4 years. At index presentation, 110 (42.0%) T2DM patients presented with ST-segment elevation myocardial infarction, 69 (26.3%) had non-ST-segment elevation myocardial infarction, 43 (16.4%) had unstable angina, and 40 (15.3%) had stable angina. After a median duration of 16.5 months (IQR: 7-29), 28.7% of the study participants had an HbA1c ≤7%. On multivariable logistic regression analysis, females were less likely to have poor glycaemic control (HbA1c above 7%) [odds ratio (OR): 0.42, 95% confidence interval (CI): 0.19-0.95, p=0.038]. Also, T2DM patients prescribed metformin monotherapy (OR: 0.34, 95% CI: 0.14-0.82, p=0.017) and patients with ST-segment depression on the electrocardiogram (OR: 0.39, 95% CI: 0.16-0.96, p=0.041) were less likely to have poor glycaemic control. Conclusion After a median duration of 16.5 months, only 28.7% of T2DM patients with CAD had an HbA1c ≤7%. This finding underscores the substantial unmet need for optimal diabetes control in this very high-risk group.

SYNTAX Score and 1-Year Outcomes in the OPTIVUS-Complex PCI Study Multivessel Cohort. Am J Cardiol 2023; 205:431-441. [PMID: 37660669 DOI: 10.1016/j.amjcard.2023.08.043] [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: 06/14/2023] [Revised: 08/01/2023] [Accepted: 08/10/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND The optimal revascularization strategy in patients with multivessel disease and intermediate SYNTAX score (SS) has not been fully elucidated. This study aimed to investigate the clinical outcomes of optimal intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) stratified by SS. METHODS This was a substudy of the OPTIVUS-Complex PCI study Multivessel Cohort, which aimed to meet the prespecified criteria for optimal stent expansion after IVUS-guided PCI. A total of 1,005 patients were divided into 3 groups according to SS: low, ≤22; intermediate, 23 to 32; and high, ≥33. The primary end points were major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of death, myocardial infarction, stroke, or coronary revascularization. RESULTS The cumulative 1-year incidence of the primary end point was significantly higher in patients with high SS than in those with intermediate or low SS (25.0%, 10.9%, and 9.5%, respectively; p = 0.003). This difference was mainly caused by the incidence of coronary revascularization. In the multivariable Cox proportional hazards models, the excess risk of patients with high versus low SS remained significant for the primary end point (hazard ratio 3.19, 95% confidence interval 1.65 to 6.16, p <0.001), whereas the excess risk of patients with intermediate versus low SS was no longer significant (hazard ratio 1.20, 95% confidence interval 0.72 to 2.01, p = 0.46). CONCLUSIONS After IVUS-guided multivessel PCI, patients with intermediate SS had a similar 1-year risk of MACCE to that of patients with low SS, whereas patients with high SS had a higher 1-year risk of MACCE than those with low SS.

Outcomes Prediction in Complex High-Risk Indicated Percutaneous Coronary Interventions in the Older Patients. Am J Cardiol 2023; 205:465-472. [PMID: 37666020 DOI: 10.1016/j.amjcard.2023.07.166] [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: 06/10/2023] [Revised: 07/27/2023] [Accepted: 07/31/2023] [Indexed: 09/06/2023]
Abstract
Complex high-risk indicated percutaneous coronary intervention (CHIP-PCI) is a poorly defined concept, which has not been validated in an older population before. This study aimed to evaluate the predictive value of the CHIP-PCI score in a large cohort of elderly patients and to identify potential further risk factors. This is a pooled analysis of 3 registries that included patients aged ≥75 years who underwent percutaneous coronary intervention from 2012 to 2019: the multicenter prospective EPIC05-Sierra 75 study, the multicenter retrospective PACO-PCI (EPIC-15) registry, and the single-center, prospective Elderly-HCD registry. A total of 2,725 patients with a mean age of 81 ± 4 years were included in the study; 269 patients (10%) met the primary end point of 1-year major adverse cardiac and cerebrovascular events (MACCEs), and 51 patients (2%) had in-hospital MACCEs. Of the 12 investigated original CHIP-PCI score variables, 5 were independent predictors: previous myocardial infarction, left ventricular ejection fraction <30%, chronic kidney disease, left main coronary artery percutaneous coronary intervention, and nonradial access. Furthermore, diabetes mellitus, anemia, and severe calcification showed to be significant predictors of MACCEs. The additional variables improved the discriminatory value of the CHIP-PCI score for 1-year MACCEs (modified CHIP-PCI score: area under the curve [AUC] 0.647 vs original CHIP-PCI score: AUC 0.598, p = 0.02) and in-hospital MACCEs (AUC 0.729 vs 0.657, p = 0.003, respectively). In conclusion, the CHIP-PCI score retains its prognostic value in older patients for in-hospital MACCEs; however, it is of limited value at 1-year follow-up. The modified CHIP-PCI score, including the 5 patient-related and 3 procedure-related factors, significantly improved its discriminatory potential.

Multi-Omics Profiling of Human Endothelial Cells from the Coronary Artery and Internal Thoracic Artery Reveals Molecular but Not Functional Heterogeneity. Int J Mol Sci 2023; 24:15032. [PMID: 37834480 PMCID: PMC10573276 DOI: 10.3390/ijms241915032] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 10/02/2023] [Accepted: 10/08/2023] [Indexed: 10/15/2023] Open
Abstract
Major adverse cardiovascular events occurring upon coronary artery bypass graft surgery are typically accompanied by endothelial dysfunction. Total arterial revascularisation, which employs both left and right internal thoracic arteries instead of the saphenous vein to create a bypass, is associated with better mid- and long-term outcomes. We suggested that molecular profiles of human coronary artery endothelial cells (HCAECs) and human internal mammary artery endothelial cells (HITAECs) are coherent in terms of transcriptomic and proteomic signatures, which were then investigated by RNA sequencing and ultra-high performance liquid chromatography-mass spectrometry, respectively. Both HCAECs and HITAECs overexpressed molecules responsible for the synthesis of extracellular matrix (ECM) components, basement membrane assembly, cell-ECM adhesion, organisation of intercellular junctions, and secretion of extracellular vesicles. HCAECs were characterised by higher enrichment with molecular signatures of basement membrane construction, collagen biosynthesis and folding, and formation of intercellular junctions, whilst HITAECs were notable for augmented pro-inflammatory signaling, intensive synthesis of proteins and nitrogen compounds, and enhanced ribosome biogenesis. Despite HCAECs and HITAECs showing a certain degree of molecular heterogeneity, no specific markers at the protein level have been identified. Coherence of differentially expressed molecular categories in HCAECs and HITAECs suggests synergistic interactions between these ECs in a bypass surgery scenario.

Everolimus-Eluting Stents or Bypass Surgery for Multivessel Disease in Diabetics: The BEST Extended Follow-Up Study. JACC Cardiovasc Interv 2023; 16:2412-2422. [PMID: 37821187 DOI: 10.1016/j.jcin.2023.07.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/14/2023] [Accepted: 07/25/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND Diabetes mellitus is associated with more complex coronary artery diseases. Coronary artery bypass grafting (CABG) is a preferred revascularization strategy over percutaneous coronary intervention (PCI) in diabetics with multivessel coronary artery disease (MVD). OBJECTIVES This study sought to examine the different prognostic effects of revascularization strategies according to the diabetes status from the randomized BEST (Randomized Comparison of Coronary Artery Bypass Surgery and Everolimus-Eluting Stent Implantation in the Treatment of Patients With Multivessel Coronary Artery Disease) trial. METHODS Patients (n = 880) with MVD were randomly assigned to undergo PCI with an everolimus-eluting stent vs CABG stratified by diabetics (n = 363) and nondiabetics (n = 517). The primary endpoint was the composite of death, myocardial infarction, or target vessel revascularization during a median follow-up of 11.8 years (IQR: 10.6-12.5 years). RESULTS In diabetics, the primary endpoint rate was significantly higher in the PCI group than in the CABG group (43% and 32%; HR: 1.53; 95% CI: 1.12-2.08; P = 0.008). However, in nondiabetics, no significant difference was found between the groups (PCI group, 29%; CABG group, 29%; HR: 0.97; 95% CI: 0.67-1.39; P = 0.86; Pinteraction= 0.009). Irrespective of the presence of diabetes, no significant between-group differences were found in the rate of a safety composite of death, myocardial infarction, or stroke and mortality rate. However, the rate of any repeat revascularization was significantly higher in the PCI group than in the CABG group. CONCLUSIONS In diabetics with MVD, CABG was associated with better clinical outcomes than PCI. However, the mortality rate was similar between PCI and CABG irrespective of diabetes status during an extended follow-up.

Abstract
OBJECTIVES The aim of the present study was to evaluate the results of isolated coronary artery bypass grafting (CABG) with or without revascularization of the occluded right coronary artery (RCA). METHODS Patients undergoing isolated CABG were included in a prospective European multicenter registry. Outcomes were adjusted for imbalance in preoperative variables with propensity score matching analysis. Late outcomes were evaluated with Kaplan-Meier's method and competing risk analysis. RESULTS Out of 2,948 included in this registry, 724 patients had a total occlusion of the RCA and were the subjects of this analysis. Occluded RCA was not revascularized in 251 (34.7%) patients with significant variability between centers. Among 245 propensity score-matched pairs, patients with and without revascularization of occluded RCA had similar early outcomes. The nonrevascularized RCA group had increased rates of 5-year all-cause mortality (17.7 vs. 11.7%, p = 0.039) compared with patients who had their RCA revascularized. The rates of myocardial infarction and repeat revascularization were only numerically increased but contributed to a significantly higher rate of MACCE (24.7 vs. 15.7%, p = 0.020) at 5 year among patients with nonrevascularized RCA. CONCLUSION In this multicenter study, one-third of totally occluded RCAs was not revascularized during isolated CABG for multivessel coronary artery disease. Failure to revascularize an occluded RCA in these patients increased the risk of all-cause mortality and MACCEs at 5 years.

Intracoronary Brachytherapy for Restenosis: 20 Years of Follow-Up. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 54:1-4. [PMID: 37087307 DOI: 10.1016/j.carrev.2023.04.009] [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: 01/24/2023] [Revised: 04/06/2023] [Accepted: 04/10/2023] [Indexed: 04/24/2023]
Abstract
BACKGROUND/PURPOSE Intracoronary brachytherapy (ICB) has mainly been used to treat in-stent restenosis following percutaneous coronary intervention and was virtually abandoned about 20 years ago. However, patients treated with this strategy are still alive and some teams continue to perform this therapy. We aimed to investigate the very long-term clinical outcome of patients treated with ICB. METHODS/MATERIALS A total of 173 consecutive patients who had been treated with ICB at a large tertiary referral centre between 1998 and 2003 were included. The primary endpoint of the study was all-cause mortality. The secondary endpoints were as follows: occurrence of major adverse cardiac events (MACE, defined as all-cause death, non-fatal myocardial infarction, or target vessel revascularization), cardiac death, and presence of angina at the end of follow-up. RESULTS Patients' mean age at the time of ICB was 64 ± 10 years and 77 % were male. Restenosis (bare metal stent vs. balloon angioplasty) was the only indication for ICB. Unstable angina was present in 34 % of the patients. Follow-up was available for 166 patients. After a mean follow-up of 20 ± 1.3 years, 66 % of the patients had died (including 74 patients (67 %) with cardiac death). Cumulative MACE rate at 20 years was 96 %. CONCLUSIONS Very long-term follow-up of patients with in-stent restenosis treated with ICB confirmed a high all-cause mortality rate mainly due to cardiac causes and MACEs.
