Abstract
BackgroundThe prognostic role of myocardial ischemia in patients with heart failure with preserved ejection fraction (HFpEF) has not been fully elucidated. Therefore, we investigated the change in echocardiographic parameters and clinical outcomes based on the presence of epicardial coronary artery disease (CAD) and positive stress tests in HFpEF patients.MethodsSymptomatic patients with left ventricular end diastolic pressure ≥15 mmHg who underwent coronary angiography were analyzed between January 2000 and August 2019 after exclusion of patients with acute coronary syndrome.ResultsA total of 555 HFpEF patients were invasively confirmed, 285 (51%) had angiographically-proven CAD. HFpEF patients with CAD displayed greater deterioration in left ventricular ejection fraction (p = 0.002) over time but this was not observed in those without CAD (p = 0.99) on follow-up echocardiography; however, the mitral annulus early diastolic velocity (e') was significantly decreased in both groups (p < 0.001 and p = 0.003, respectively). Among 274 patients that received stress tests, those with positive stress tests showed a decline in e' (p 0.001), but this was not found in subjects with negative stress tests (p = 0.44). There was no significant difference in all-cause mortality between patients with CAD and without CAD (p = 0.26) with a median follow-up of 10.6 years.ConclusionIn HFpEF patients, CAD was associated with greater deterioration in the left ventricular systolic function but not with mortality during the follow-up. In addition, myocardial ischemia with a positive stress test may contribute to greater deterioration of diastolic dysfunction.

External validation and comparison of two delirium prediction models in patients admitted to the cardiac intensive care unit. Front Cardiovasc Med 2022; 9:947149.

Abstract
Background No data is available on delirium prediction models in the cardiac intensive care unit (CICU), although preexisting delirium prediction models [PREdiction of DELIRium in ICu patients (PRE-DELIRIC) and Early PREdiction of DELIRium in ICu patients (E-PRE-DELIRIC)] were developed and validated based on a population admitted to the general intensive care unit (ICU). Therefore, we externally validated the usefulness of the PRE-DELIRIC and E-PRE-DELIRIC models and compared their predictive performance in patients admitted to the CICU. Methods A total of 2,724 patients admitted to the CICU were enrolled between September 2012 and December 2018. Delirium was defined as at least one positive Confusion Assessment Method for the ICU (CAM-ICU) which was screened at least once every 8 h. The PRE-DELIRIC value was calculated within 24 h of CICU admission, and the E-PRE-DELIRIC value was calculated at CICU admission. The predictive performance of the models was evaluated by using the area under the receiver operating characteristic (AUROC) curve, and the calibration slope was assessed graphically by plotting. Results Delirium occurred in 677 patients (24.8%) when the patients were assessed thrice daily until 7 days of the CICU stay. The AUROC curve for the prediction of delirium was significantly greater for PRE-DELIRIC values [0.84, 95% confidence interval (CI): 0.82–0.86] than for E-PRE-DELIRIC values (0.79, 95% CI: 0.77–0.80) [z score of −6.24 (p < 0.001)]. Net reclassification improvement for the prediction of delirium increased by 0.27 (95% CI: 0.21–0.32, p < 0.001). Calibration was acceptable in the PRE-DELIRIC model (Hosmer-Lemeshow p = 0.170) but not in the E-PRE-DELIRIC model (Hosmer-Lemeshow p < 0.001). Conclusion Although both models have good predictive performance for the development of delirium, even in critically ill cardiac patients, the performance of the PRE-DELIRIC model might be superior to that of the E-PRE-DELIRIC model. Further studies are required to confirm our results and design a specific delirium prediction model for CICU patients.

Abstract
Background Several studies have shown that obesity is associated with better outcomes in patients with cardiogenic shock (CS). Although this phenomenon, the “obesity paradox,” reportedly manifests differently based on sex in other disease entities, it has not yet been investigated in patients with CS. Methods and Results A total of 1227 patients with CS from the RESCUE (Retrospective and Prospective Observational Study to Investigate Clinical Outcomes and Efficacy of Left Ventricular Assist Device for Korean Patients With Cardiogenic Shock) registry in Korea were analyzed. The study population was classified into obese and nonobese groups according to Asian Pacific criteria (BMI ≥25.0 kg/m2 for obese). The clinical impact of obesity on in‐hospital mortality according to sex was analyzed using logistic regression analysis and restricted cubic spline curves. The in‐hospital mortality rate was significantly lower in obese men than nonobese men (34.2% versus 24.1%, respectively; P=0.004), while the difference was not significant in women (37.3% versus 35.8%, respectively; P=0.884). As a continuous variable, higher BMI showed a protective effect in men; conversely, BMI was not associated with clinical outcomes in women. Compared with patients with normal weight, obesity was associated with a decreased risk of in‐hospital death in men (multivariable‐adjusted odds ratio [OR], 0.63; CI, 0.43–0.92 [P=0.016]), but not in women (multivariable‐adjusted OR, 0.94; 95% CI, 0.55–1.61 [P=0.828]). The interaction P value for the association between BMI and sex was 0.023. Conclusions The obesity paradox exists and apparently occurs in men among patients with CS. The differential effect of BMI on in‐hospital mortality was observed according to sex. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT02985008.

Abstract
ObjectivesWhile coronary computed tomography angiography (CCTA) enables the evaluation of anatomic and hemodynamic plaque characteristics of coronary artery disease (CAD), the clinical roles of these characteristics are not clear. We sought to evaluate the prognostic implications of CCTA-derived anatomic and hemodynamic plaque characteristics in the prediction of subsequent coronary events.MethodsThe study cohort consisted of 158 patients who underwent CCTA with suspected CAD within 6–36 months before percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) or unstable angina and age-/sex-matched 62 patients without PCI as the control group. Preexisting high-risk plaque characteristics (HRPCs: low attenuation plaque, positive remodeling, napkin-ring sign, spotty calcification, minimal luminal area <4 mm2, or plaque burden ≥70%) and hemodynamic parameters (per-vessel fractional flow reserve [FFRCT], per-lesion ΔFFRCT, and percent ischemic myocardial mass) were analyzed from prior CCTA. The primary outcome was a subsequent coronary event, which was defined as a composite of vessel-specific MI or revascularization for unstable angina. The prognostic impact of clinical risk factors, HRPCs, and hemodynamic parameters were compared between vessels with (160 vessels) and without subsequent coronary events (329 vessels).ResultsVessels with a subsequent coronary event had higher number of HRPCs (2.6 ± 1.4 vs. 2.3 ± 1.4, P = 0.012), lower FFRCT (0.76 ± 0.13 vs. 0.82 ± 0.11, P < 0.001), higher ΔFFRCT (0.14 ± 0.12 vs. 0.09 ± 0.08, P < 0.001), and higher percent ischemic myocardial mass (29.0 ± 18.5 vs. 26.0 ± 18.4, P = 0.022) than those without a subsequent coronary event. Compared with clinical risk factors, HRPCs and hemodynamic parameters showed higher discriminant abilities for subsequent coronary events with ΔFFRCT being the most powerful predictor. HRPCs showed additive discriminant ability to clinical risk factors (c-index 0.620 vs. 0.558, P = 0.027), and hemodynamic parameters further increased discriminant ability (c-index 0.698 vs. 0.620, P = 0.001) and reclassification abilities (NRI 0.460, IDI 0.061, P < 0.001 for all) for subsequent coronary events. Among vessels with negative FFRCT (>0.80), adding HRPCs into clinical risk factors significantly increased discriminant and reclassification abilities for subsequent coronary events (c-index 0.687 vs. 0.576, P = 0.005; NRI 0.412, P = 0.002; IDI 0.064, P = 0.001) but not for vessels with positive FFRCT (≤0.80).ConclusionIn predicting subsequent coronary events, both HRPCs and hemodynamic parameters by CCTA allow better prediction of subsequent coronary events than clinical risk factors. HRPCs provide more incremental predictability than clinical risk factors alone among vessels with negative FFRCT but not among vessels with positive FFRCT.Clinical Trial RegistrationPreDiction and Validation of Clinical CoursE of Coronary Artery DiSease With CT-Derived Non-INvasive HemodYnamic Phenotyping and Plaque Characterization (DESTINY Study), NCT04794868.

Abstract
BACKGROUND Because no data were available regarding the effect of preexisting left ventricular filling pressure (LVFP) on clinical outcomes in patients with acute myocardial infarction (AMI), we evaluated whether preexisting high LVFP can determine outcomes of subsequent AMI events. METHODS AND RESULTS Among 399,613 subjects who underwent echocardiography for various reason from August 2004 to June 2019, 231 had experienced subsequent AMI and were stratified according to preexisting LVFP: low LVFP (E/e' ≤14) and high LVFP (E/e' >14). The primary outcome was cardiac death at 30 days and 1 year after AMI. Overall, 19.5% had high LVFP prior to AMI events. Preexisting high LVFP was associated with an increased risk of cardiac death at 30 days (3.8% vs. 11.6%; adjusted hazard ratio (HR) 4.56, 95% confidence interval (CI) 1.20-17.24, P=0.026) and 1 year after AMI (7.9% vs. 35.9%; adjusted HR 4.14, 95% CI 1.79-9.57, P<0.001). Preexisting E/e' as a continuous value was significantly associated with 1-year risk of cardiac death (adjusted HR 1.08, 95% CI 1.02-1.15, P=0.007). Follow-up echocardiography showed that patients with high LVFP did not show improvement in systolic or diastolic function. CONCLUSIONS Preexisting high LVFP was associated with poor clinical course and 1-year cardiac death after subsequent AMI, as well as no improvement in systolic or diastolic function.

Abstract
BACKGROUND Although P2Y12 inhibitor monotherapy has emerged as a promising alternative for dual antiplatelet therapy (DAPT), there remains concern regarding the safety of clopidogrel monotherapy. AIMS We sought to investigate clinical outcomes of clopidogrel monotherapy in patients with and without on-treatment high platelet reactivity (HPR). METHODS In the SMART-CHOICE study, three-month DAPT followed by P2Y12 inhibitor monotherapy was compared with 12-month DAPT in patients undergoing percutaneous coronary intervention. A platelet function test was performed for 833 patients with clopidogrel-based therapy. The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE: a composite of all-cause death, myocardial infarction, or stroke) at 12 months. RESULTS Overall, 108 (13.0%) patients had HPR on clopidogrel. Patients with HPR had a significantly higher rate of MACCE than patients without HPR (8.7% vs 1.5%, adjusted HR 3.036, 95% CI: 1.060-8.693, p=0.038). The treatment effect of clopidogrel monotherapy for the 12-month MACCE was not significantly different compared with DAPT among patients with HPR (8.0% vs 9.4%, adjusted HR 0.718, 95% CI: 0.189-2.737, p=0.628) and without HPR (2.2% vs 0.9%, adjusted HR 2.587, 95% CI: 0.684-9.779, p=0.161; adjusted p for interaction=0.170). CONCLUSIONS Clopidogrel monotherapy showed treatment effects comparable to DAPT for MACCE in patients with or without HPR. However, HPR was significantly associated with an increased risk of MACCE in clopidogrel-treated patients regardless of maintenance of aspirin.

Abstract
Little is known about causality and the pathological mechanism underlying the association of serum lactate with myocardial injury in patients with acute myocardial infarction (AMI). We evaluated data from 360 AMI patients undergoing percutaneous coronary intervention (PCI) using cardiovascular magnetic resonance imaging (CMR). Of these, 119 patients had serum lactate levels > 2.5 mmol/L on admission (high serum lactate group), whereas 241 patients had serum lactate levels ≤ 2.5 mmol/L (low serum lactate group). We compared the myocardial infarct size assessed by CMR between the two groups and performed inverse probability of treatment weighting (IPTW). In CMR analysis, myocardial infarct size was significantly greater in the high serum lactate group than in the low serum lactate group (22.0 ± 11.4% in the high serum lactate group vs. 18.9 ± 10.5% in the low serum lactate group; p = 0.011). The result was consistent after IPTW adjustment (21.5 ± 11.1% vs. 19.2 ± 10.4%; p = 0.044). In multivariate analysis, high serum lactate was associated with larger myocardial infarct (odds ratio 1.59; 95% confidence interval 1.00–2.51; p = 0.048). High serum lactate could predict advanced myocardial injury in AMI patients undergoing PCI.

Abstract
BACKGROUND Acute cellular rejection is a major determinant of mortality and retransplantation after heart transplantation. We sought to evaluate the prognostic implications of coronary microcirculatory dysfunction assessed by index of microcirculatory resistance (IMR) for the risk of acute cellular rejection after heart transplantation. METHODS The present study prospectively enrolled 154 heart transplant recipients who underwent scheduled coronary angiography and invasive coronary physiological assessment 1 month after transplantation. IMR is microcirculatory resistance under maximal hyperemia. By measuring hyperemic mean transit time using 3 injections (4 mL each) of room-temperature saline under maximal hyperemia, IMR was calculated as hyperemic distal coronary pressure×hyperemic mean transit time. The primary end point was biopsy-proven acute cellular rejection of grade ≥2R during 2 years of follow-up after transplantation and was compared by using multivariable Cox proportional hazards regression according to IMR. The incremental prognostic value of IMR, in addition to the model with clinical factors, was evaluated by comparison of C-index, net reclassification index, and integrated discrimination index. RESULTS The mean age of recipients was 51.2±13.1 years (81.2% male), and the cumulative incidence of acute cellular rejection was 19.0% at 2 years. Patients with acute cellular rejection had significantly higher IMR values at 1 month than those without acute cellular rejection (23.1±8.6 versus 16.8±11.1, P=0.002). IMR was significantly associated with the risk of acute cellular rejection (per 5-U increase: adjusted hazard ratio, 1.18 [95% CI, 1.04-1.34], P=0.011) and the optimal cutoff value of IMR to predict acute cellular rejection was 15. Patients with IMR≥15 showed significantly higher risk of acute cellular rejection than those with IMR<15 (34.4% versus 3.8%; adjusted hazard ratio, 15.3 [95% CI 3.6-65.7], P<0.001). Addition of IMR to clinical variables showed significantly higher discriminant and reclassification ability for risk of acute cellular rejection (C-index 0.87 versus 0.74, P<0.001; net reclassification index 1.05, P<0.001; integrated discrimination index 0.20, P<0.001). CONCLUSIONS Coronary microcirculatory dysfunction assessed by IMR measured early after heart transplantation showed significant association with the risk of acute cellular rejection. In addition to surveillance endomyocardial biopsy, early stratification using IMR could be a clinically useful tool to identify patients at higher risk of future acute cellular rejection after heart transplantation.

Abstract
BACKGROUND The current study sought to investigate the association between statin intensity and long-term clinical outcomes according to initial clinical presentation following CABG. METHODS A total of 6,531 patients who underwent CABG were finally included in this study, and the study population was classified into four groups according to statin intensity (no or low[atorvastatin<10mg,n=731], lower-moderate[atorvastatin 10mg equivalent,n=2310], higher-moderate [atorvastatin 20mg equivalent,n=2404], and high-intensity [atorvastatin≥40mg equivalent, n=1086]). The primary endpoint was MACCE at 5-years. Multivariable Cox and inverse-probability-weighting methods were performed to adjust for baseline differences. RESULTS At least moderate-intensity statin use was associated with significantly lower risk of 5-year MACCE compared with no or low-intensity statin use(HR 0.694,95%CI:0.493-0.977,p=0.036). Among patients who were taken at-least moderate-intensity statin, both higher moderate-intensity(HR:0.622,95%CI:0.479-0.807,p<0.001) and high-intensity statin(HR:0.613,95%CI:0.421-0.894,p=0.011) groups showed significantly lower risks of MACCE than lower-moderate intensity statin group at 5-years after CABG. There was no significant difference in the risk of MACCE between higher-moderate intensity and high-intensity statin groups(HR:0.987,95%CI:0.661-1.475,p=0.950). Multivariable Cox and inverse-probability-weighting methods yielded similar results. In subgroup analysis, compared with the use of a lower-moderate intensity statin, the use of a higher-moderate or high-intensity statin(equivalent dose with atorvastatin≥20mg) was associated with a significantly lower risk of MACCE among CABG patients who presented with ACS, but not in those who presented with stable ischemic heart disease(interaction-p=0.001). CONCLUSIONS The use of a lower-moderate intensity statin(atorvastatin 10mg equivalent) was associated with relatively poorer long-term clinical outcomes than the use of higher-moderate or high-intensity statin, especially in ACS patients following CABG.

Abstract
Background Despite advances in devices and techniques, coronary bifurcation lesion remains a challenging lesion subset in the field of percutaneous coronary intervention (PCI). We evaluate 10‐year trends in bifurcation PCI and their effects on patient outcomes. Methods and Results We analyzed 10‐year trends in patient/lesion characteristics, devices, PCI strategy, stent optimization techniques, and clinical outcomes using data from 5498 patients who underwent bifurcation PCI from 2004 to 2015. Clinical outcomes 2 years after the index procedure were evaluated in terms of target vessel failure (a composite of cardiac death, myocardial infarction, and target vessel revascularization) and a patient‐oriented composite outcome (a composite of all‐cause death, myocardial infarction, and any revascularization). During the 10‐year study period, patient and lesion complexity, such as multivessel disease, diabetes mellitus, chronic kidney disease, and left main bifurcation, increased continuously (all P<0.001). The risk of target vessel failure or patient‐oriented composite outcome decreased continuously from 2004 to 2015 (target vessel failure: from 12.3% to 6.9%, log‐rank P<0.001; patient‐oriented composite outcome: from 13.6% to 9.3%, log‐rank P<0.001). The use of a second‐generation drug‐eluting stent and decreased target vessel failure risk in true bifurcation lesions were the major contributors to improved patient prognosis (interaction P values were <0.001 and 0.013, respectively). Conclusions During the past decade of bifurcation PCI, patient and lesion characteristics, devices, PCI techniques, and patient prognosis have all significantly changed. Despite increased patient and lesion complexity, clinical outcomes after bifurcation PCI have improved, mainly because of better devices and more widespread adoption of procedural optimization techniques and appropriate treatment strategies.

P2Y12 inhibitor monotherapy in complex percutaneous coronary intervention: A post-hoc analysis of SMART-CHOICE randomized clinical trial. Cardiol J 2021; 28:855-863. [PMID: 34523115 PMCID: PMC8747822 DOI: 10.5603/cj.a2021.0101] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 08/17/2021] [Accepted: 08/21/2021] [Indexed: 11/25/2022] Open
Abstract
Background It remains unclear whether P2Y12 monotherapy, especially clopidogrel, following short-duration dual antiplatelet therapy (DAPT) is associated with favorable outcomes in patients undergoing complex percutaneous coronary intervention (PCI). Therefore, this study analyzed the efficacy and safety of P2Y12 inhibitor monotherapy, mostly clopidogrel (78%), in complex PCI following short-term DAPT. Methods The post-hoc analysis of the SMART-CHOICE trial involving 2,993 patients included 498 cases of complex PCIs, defined by at least one of the following features: 3 vessels treated, ≥ 3 stents implanted, ≥ 3 lesions treated, bifurcation with ≥ 2 stents implanted, and a total stent length of ≥ 60 mm. The primary endpoint was major adverse cardiac and cerebrovascular event (MACCE), defined as the composite of all-cause death, myocardial infarction, and stroke. The primary safety endpoint included bleeding, defined as Bleeding Academic Research Consortium (BARC) types 2 to 5. Results Complex PCI group had a higher risk of MACCE (4.0% vs. 2.3%, hazard ratio [HR] = 1.74, 95% confidence interval [CI]: 1.05–2.89, p = 0.033) and a similar risk of BARC types 2–5 bleeding (2.6% vs. 2.6%, HR = 1.02, 95% CI: 0.56–1.86, p = 0.939) compared with those without complex PCIs. Patients undergoing complex PCIs, followed by P2Y12 inhibitor monotherapy and 12 months of DAPT exhibited similar rates of MACCE (3.8% vs. 4.2%, HR = 0.92, 95% CI: 0.38–2.21, p = 0.853). Conclusions P2Y12 inhibitor monotherapy, mostly clopidogrel, following 3 months of DAPT did not increase ischemic events in patients with complex PCIs.

Clinical and Prognostic Impact From Objective Analysis of Post-Angioplasty Fractional Flow Reserve Pullback. JACC Cardiovasc Interv 2021; 14:1888-1900. [PMID: 34503739 DOI: 10.1016/j.jcin.2021.07.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 06/21/2021] [Accepted: 07/08/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES This study sought to evaluate clinical implications of the residual fractional flow reserve (FFR) gradient after angiographically successful percutaneous coronary intervention (PCI). BACKGROUND Recent studies have demonstrated FFR measured after PCI is associated with clinical outcome after PCI. Although post-PCI FFR pull back tracings provide clinically relevant information on the residual FFR gradient, there are no objective criteria for assessing post-PCI FFR pull back tracings. METHODS A total of 492 patients who underwent angiographically successful PCI and post-PCI FFR measurement with pull back tracings were analyzed. The presence of the major residual FFR gradient after PCI was assessed by both conventional visual interpretation of the pull back tracings and objective analysis using the instantaneous FFR gradient per unit time (dFFR(t)/dt) with a cutoff value of dFFR(t)/dt ≥0.035. Classification agreement between 2 independent operators for the presence of the major residual FFR gradient was compared before and after providing dFFR(t)/dt results. Target vessel failure (TVF), a composite of cardiac death, target vessel myocardial infarction, or clinically driven target vessel revascularization at 2 years, was compared according to the presence of the major residual FFR gradient. RESULTS Among the study population, 33.9% had the major residual FFR gradient defined by dFFR(t)/dt. The classification agreement between operators' assessments for the major residual FFR gradient increased with dFFR(t)/dt results compared with conventional visual assessment (Cohen's kappa = 0.633 to 0.819; P < 0.001; intraclass correlation coefficient: 0.776 to 0.901; P < 0.001). Patients with major residual FFR gradient were associated with a higher risk of TVF at 2 years than those without major residual FFR gradient (9.0% vs 2.2%; P < 0.001). Inclusion of the major residual FFR gradient to a clinical prediction model significantly increased discrimination and reclassification ability (C-index = 0.539 vs 0.771; P = 0.006; net reclassification improvement = 0.668; P = 0.007; integrated discrimination improvement = 0.033; P = 0.017) for TVF at 2 years. The presence of the major residual FFR gradient was independently associated with TVF at 2 years, regardless of post-PCI FFR or percent FFR increase (adjusted hazard ratio: 3.930; 95% confidence interval: 1.353-11.420; P = 0.012). CONCLUSIONS Objective analysis of post-PCI FFR pull back tracings using dFFR(t)/dt improved classification agreement on the presence of the major residual FFR gradient among operators. Presence of the major residual FFR gradient defined by dFFR(t)/dt after angiographically successful PCI was independently associated with an increased risk of TVF at 2 years.

Physiological Distribution and Local Severity of Coronary Artery Disease and Outcomes After Percutaneous Coronary Intervention. JACC Cardiovasc Interv 2021; 14:1771-1785.

Abstract
OBJECTIVES The aim of this study was to evaluate prognostic implications of physiological 2-dimensional disease patterns on the basis of distribution and local severity of coronary atherosclerosis determined by quantitative flow ratio (QFR) virtual pull back. BACKGROUND The beneficial effect of percutaneous coronary intervention (PCI) is determined by physiological distribution and local severity of coronary atherosclerosis. METHODS The study population included 341 patients who underwent angiographically successful PCI and post-PCI fractional flow reserve (FFR) measurement. Using pre-PCI virtual pull backs of QFR, physiological distribution was determined by pull back pressure gradient index, with a cutoff value of 0.78 to define predominant focal versus diffuse disease. Physiological local severity was assessed by instantaneous QFR gradient per unit length, with a cutoff value of ≥0.025/mm to define a major gradient. Suboptimal post-PCI physiological results were defined as both post-PCI FFR ≤0.85 and percentage FFR increase ≤15%. Clinical outcome was assessed by target vessel failure (TVF) at 2 years. RESULTS QFR pull back pressure gradient index was correlated with post-PCI FFR (R = 0.423; P < 0.001), and instantaneous QFR gradient per unit length was correlated with percentage FFR increase (R = 0.370; P < 0.001). Using the 2 QFR-derived indexes, disease patterns were classified into 4 categories: predominant focal disease with and without major gradient (group 1 [n = 150] and group 2 [n = 21], respectively) and predominant diffuse disease with and without major gradient (group 3 [n = 115] and group 4 [n = 55], respectively). Proportions of suboptimal post-PCI physiological results were significantly different according to the 4 disease patterns (18.7%, 23.8%, 22.6%, and 56.4% from group 1 to group 4, respectively; P < 0.001). Cumulative incidence of TVF after PCI was significantly higher in patients with predominant diffuse disease (8.1% in group 3 and 9.9% in group 4 vs 1.4% in group 1 and 0.0% in group 2; overall P = 0.024). CONCLUSIONS Both physiological distribution and local severity of coronary atherosclerosis could be characterized without pressure-wire pull backs, which determined post-PCI physiological results. After successful PCI, TVF risk was determined mainly by the physiological distribution of coronary atherosclerosis.

Abstract
BACKGROUND Data on direct comparison between various drug-eluting stents with short duration dual antiplatelet therapy (DAPT) are limited, especially in patients with acute coronary syndrome (ACS). AIMS We sought to compare biodegradable polymer biolimus-eluting stents (BP-BES) with durable polymer everolimus-eluting (DP-EES) and zotarolimus-eluting stents (DP-ZES) in patients with ACS according to different durations of DAPT. METHODS In the SMART-DATE trial, 2,712 patients with ACS underwent randomisation for allocation of DAPT (6 months [n=1,357] or 12 months or longer [n=1,355]) and type of stent (BP-BES [n=901]), DP-EES [n=904], or DP-ZES [n=907]). The primary endpoint was a composite of cardiac death, myocardial infarction, or stent thrombosis. RESULTS At 18 months, the primary endpoint was attained by 2.6% with BP-BES, 2.0% with DP-EES, and 2.1% with DP-ZES (HR 1.29, 95% CI: 0.70-2.39, p=0.42 for BP-BES vs DP-EES and HR 1.23, 95% CI: 0.67-2.26, p=0.50 for BP-BES vs DP-ZES). The treatment effect of BP-BES for the primary endpoint was consistent among patients receiving 6-month DAPT as well as those receiving 12-month or longer DAPT (BP-BES vs. DP-EES, pinteraction=0.48 and BP-BES vs DP-ZES, pinteraction=0.87). After excluding 179 patients (101 in the BP-BES group) who did not receive allocated DES, the per-protocol analysis showed similar results. CONCLUSIONS The risk of a composite of cardiac death, myocardial infarction, or stent thrombosis was not significantly different between patients receiving BP-BES versus DP-EES or DP-ZES across a short or prolonged duration of DAPT after ACS.

Abstract
OBJECTIVE We investigated the gender difference in the 5-year outcome after percutaneous coronary intervention (PCI) using an unselected population data. BACKGROUND Sex-specific outcome after percutaneous coronary intervention (PCI) is not consistent among studies. METHODS A total of 48,783 patients were enrolled from a Korean nationwide cohort of PCI in year 2011. Outcomes adjusted with age and propensity for clinical characteristics were compared. Primary outcome was 5-year cumulative incidence of all-cause death. Nonfatal major adverse clinical event (MACE) consisting of revascularization, shock, or stroke was also assessed. RESULTS In unadjusted analysis, women were older and had higher frequency of comorbidities including hypertension, hyperlipidemia, and diabetes compared to men (p < .001, all). Women had higher 5-year death risk than men (21.8 vs. 17.3%; hazard ratio [HR] 1.29, 95% confidential interval [CI] 1.23-1.34). In propensity score-matched analysis (N = 28,924), women had lower 5-year death risk (20.2 vs. 26.1%, HR 0.75, 95% CI 0.71-0.78). This lower death risk in women was consistent in subgroup analyses of age, risk factors, and clinical diagnosis including angina or acute myocardial infarction (p < .05, all). CONCLUSIONS Older age and more common comorbidities in women contributed to the apparent worse outcome after PCI in women. After adjusting these disadvantages, women had better outcome after PCI than men.

Abstract
OBJECTIVES The aim of this study was to evaluate the diagnostic accuracy and prognostic implications of angiography-derived index of microcirculatory resistance (angio-IMR) in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND The index of microcirculatory resistance (IMR) is a reliable invasive measure of coronary microvascular dysfunction in patients with STEMI. A functional coronary angiography-derived method to estimate IMR is a wire- and hyperemic agent-free alternative to IMR. METHODS The study population consisted of 2 independent cohorts. The diagnostic cohort comprised patients with IMR from the culprit vessel immediately after successful primary percutaneous coronary intervention (n = 31). The prognostic cohort was patients with STEMI who were successfully treated with primary percutaneous coronary intervention and followed for 10 years from the index procedure (n = 309). Angio-IMR was calculated using computational flow and pressure simulation. The primary outcome was a composite of cardiac death and readmission for heart failure over 10 years of follow-up. RESULTS In the diagnostic cohort, angio-IMR correlated well with IMR (R = 0.778; P < 0.001). Sensitivity, specificity, accuracy, and area under the curve of angio-IMR to predict IMR >40 U were 75.0%, 84.2%, 80.6%, and 0.899 (95% confidence interval: 0.786-0.949), respectively. In the prognostic cohort, patients with angio-IMR >40 U showed significantly higher risk for cardiac death or readmission for heart failure than did those with angio-IMR ≤40 U (46.7% vs 16.6%; adjusted hazard ratio: 2.909; 95% CI: 1.670-5.067; P < 0.001). Angio-IMR >40 U was an independent predictor of cardiac death or readmission for heart failure (hazard ratio: 2.173; 95% CI: 1.157-4.079; P = 0.016) and showed incremental prognostic value compared with a model with clinical risk factors only (C index = 0.726 vs 0.666 [P < 0.001], net reclassification index = 0.704 [P < 0.001]). CONCLUSIONS Angio-IMR showed high correlation and diagnostic accuracy to predict IMR. Patients with STEMI with angio-IMR >40 U showed a significantly higher risk for cardiac death or readmission for heart failure than those with preserved angio-IMR values.

Abstract
OBJECTIVE To assess the risks and benefits of P2Y12 inhibitor monotherapy compared with dual antiplatelet therapy (DAPT) and whether these associations are modified by patients' characteristics. DESIGN Individual patient level meta-analysis of randomised controlled trials. DATA SOURCES Searches were conducted in Ovid Medline, Embase, and three websites (www.tctmd.com, www.escardio.org, www.acc.org/cardiosourceplus) from inception to 16 July 2020. The primary authors provided individual participant data. ELIGIBILITY CRITERIA Randomised controlled trials comparing effects of oral P2Y12 monotherapy and DAPT on centrally adjudicated endpoints after coronary revascularisation in patients without an indication for oral anticoagulation. MAIN OUTCOME MEASURES The primary outcome was a composite of all cause death, myocardial infarction, and stroke, tested for non-inferiority against a margin of 1.15 for the hazard ratio. The key safety endpoint was Bleeding Academic Research Consortium (BARC) type 3 or type 5 bleeding. RESULTS The meta-analysis included data from six trials, including 24 096 patients. The primary outcome occurred in 283 (2.95%) patients with P2Y12 inhibitor monotherapy and 315 (3.27%) with DAPT in the per protocol population (hazard ratio 0.93, 95% confidence interval 0.79 to 1.09; P=0.005 for non-inferiority; P=0.38 for superiority; τ2=0.00) and in 303 (2.94%) with P2Y12 inhibitor monotherapy and 338 (3.36%) with DAPT in the intention to treat population (0.90, 0.77 to 1.05; P=0.18 for superiority; τ2=0.00). The treatment effect was consistent across all subgroups, except for sex (P for interaction=0.02), suggesting that P2Y12 inhibitor monotherapy lowers the risk of the primary ischaemic endpoint in women (hazard ratio 0.64, 0.46 to 0.89) but not in men (1.00, 0.83 to 1.19). The risk of bleeding was lower with P2Y12 inhibitor monotherapy than with DAPT (97 (0.89%) v 197 (1.83%); hazard ratio 0.49, 0.39 to 0.63; P<0.001; τ2=0.03), which was consistent across subgroups, except for type of P2Y12 inhibitor (P for interaction=0.02), suggesting greater benefit when a newer P2Y12 inhibitor rather than clopidogrel was part of the DAPT regimen. CONCLUSIONS P2Y12 inhibitor monotherapy was associated with a similar risk of death, myocardial infarction, or stroke, with evidence that this association may be modified by sex, and a lower bleeding risk compared with DAPT.

Abstract
BACKGROUND In the current era of mechanical circulatory support, limited data are available on prognosis of cardiogenic shock (CS) caused by various diseases. We investigated the characteristics and predictors of in-hospital mortality in Korean patients with CS. METHODS The RESCUE study (Retrospective and Prospective Observational Study to Investigate Clinical Outcomes and Efficacy of Left Ventricular Assist Device for Korean Patients With CS) is a multicenter, retrospective, and prospective registry of patients that presented with CS. Between January 2014 and December 2018, 1247 patients with CS were enrolled from 12 major centers in Korea. The primary outcome was in-hospital mortality. RESULTS In-hospital mortality rate was 33.6%. The main causes of shock were ischemic heart disease (80.7%), dilated cardiomyopathy (6.1%), myocarditis (3.2%), and nonischemic ventricular arrhythmia (2.5%). Vasopressors were used in 1081 patients (86.7%). The most frequently used vasopressor was dopamine (63.4%) followed by norepinephrine (57.3%). An intraaortic balloon pump was used in 314 patients (25.2%) and extracorporeal membrane oxygenator in 496 patients (39.8%). In multivariable analysis, age ≥70years (odds ratio [OR], 2.73 [95% CI, 1.89-3.94], P<0.001), body mass index <25 kg/m2 (OR, 1.52 [95% CI, 1.08-2.16], P=0.017), cardiac arrest at presentation (OR, 2.16 [95% CI, 1.44-3.23], P<0.001), vasoactive-inotrope score >80 (OR, 3.55 [95% CI, 2.54-4.95], P<0.001), requiring continuous renal replacement therapy (OR, 4.14 [95% CI, 2.88-5.95], P<0.001), mechanical ventilator (OR, 3.17 [95% CI, 2.16-4.63], P<0.001), intraaortic balloon pump (OR, 1.55 [95% CI, 1.07-2.24], P=0.020), and extracorporeal membrane oxygenator (OR, 1.85 [95% CI, 1.25-2.76], P=0.002) were independent predictors for in-hospital mortality. CONCLUSIONS The in-hospital mortality of patients with CS remains high despite the high utilization of mechanical circulatory support. Age, low body mass index, cardiac arrest at presentation, amount of vasopressor, and advanced organ failure requiring various support devices were poor prognostic factors for in-hospital mortality.

Abstract
OBJECTIVE To compare P2Y12 inhibitor monotherapy after 3-month dual antiplatelet therapy (DAPT) with 12-month DAPT according to the type of P2Y12 inhibitor in patients undergoing percutaneous coronary intervention (PCI). METHODS The Smart Angioplasty Research Team: Comparison Between P2Y12 Antagonist Monotherapy vs Dual Antiplatelet Therapy in Patients Undergoing Implantation of Coronary Drug-Eluting Stents (SMART-CHOICE) randomised trial compared 3-month DAPT followed by P2Y12 inhibitor monotherapy with 12-month DAPT. In this trial, 2993 patients undergoing successful PCI with drug-eluting stent were enrolled in Korea. As a prespecified analysis, P2Y12 inhibitor monotherapy after 3-month DAPT versus 12-month DAPT were compared among patients receiving clopidogrel and those receiving potent P2Y12 inhibitor (ticagrelor or prasugrel), respectively. The primary endpoint was a composite of all-cause death, myocardial infarction or stroke at 12 months after the index procedure. RESULTS Among 2993 patients (mean age 64 years), 58.2% presented with acute coronary syndrome. Clopidogrel was prescribed in 2312 patients (77.2%) and a potent P2Y12 inhibitor in 681 (22.8%). There were no significant differences in the primary endpoint between the P2Y12 inhibitor monotherapy group and the DAPT group among patients receiving clopidogrel (3.0% vs 3.0%; HR: 1.02; 95% CI 0.64 to 1.65; p=0.93) as well as among patients receiving potent P2Y12 inhibitors (2.4% vs 0.7%; HR: 3.37; 95% CI 0.77 to 14.78; p=0.11; interaction p=0.1). Among patients receiving clopidogrel, P2Y12 inhibitor monotherapy compared with DAPT showed consistent treatment effects across various subgroups for the primary endpoint. Among patients receiving potent P2Y12 inhibitors, the rate of bleeding (Bleeding Academic Research Consortium types 2- 5) was significantly lower in the P2Y12 inhibitor monotherapy group than in the DAPT group (1.5% vs 5.0%; HR: 0.33; 95% CI 0.12 to 0.87; p=0.03). CONCLUSIONS Compared with 12-month DAPT, clopidogrel monotherapy after 3-month DAPT showed comparable cardiovascular outcomes in patients undergoing PCI. TRIAL REGISTRATION NUMBER NCT02079194.

Abstract
BACKGROUND There is a paucity of data regarding the long-term clinical outcomes of first- versus second-generation drug-eluting stent (DES), especially when used to treat complex lesions such as bifurcation lesions. OBJECTIVES The current study compares the efficacy and safety of first- versus second-generation DES at the 5-year follow-up in patients who underwent bifurcation percutaneous coronary intervention (PCI). METHODS A total of 5,498 patients with a bifurcation lesion who underwent PCI were pooled at a single patient level from COBIS (Coronary Bifurcation Stenting) registries II and III. Five-year target lesion failure (TLF) (the composite of cardiac death, myocardial infarction [MI], and target lesion revascularization [TLR]) and cardiac death or MI were compared between the use of first-generation DES (n = 2,436) and second-generation DES (n = 3,062) during PCI. Propensity score matching was performed to reduce selection bias. RESULTS After a 1:1 propensity score matching procedure was conducted, the cohort consisted of 1,702 matched pairs. Patients treated with second-generation DES had a significantly lower risk of TLF at 5 years than those treated with first-generation DES in both overall and propensity-matched populations (matched hazard ratio [HRmatched]: 0.576; 95% confidence interval [CI]: 0.456 to 0.727; p <0.001). There were no significant differences in risk of a composite of cardiac death or MI between the 2 groups (HRmatched: 0.782; 95% CI: 0.539 to 1.133, P = 0.193). However, among patients who required a 2-stent technique, use of the second-generation DES reduced cardiac death or MI (HRmatched:0.422; 95% CI: 0.209 to 0.851, P = 0.016). On the other hand, among patients who required a one-stent technique, the risk of a composite of cardiac death or MI was similar between the 2 groups (HRmatched: 1.046; 95% CI: 0.664 to 1.650, P = 0.845). There was a significant interaction between stent generation and treatment strategy for cardiac death or MI (interaction P = 0.029). CONCLUSIONS In patients treated with PCI for a bifurcation lesion, the use of second-generation DES was associated with a significantly reduced risk of 5-year TLF than the use of first-generation DES.

Abstract
BACKGROUND The benefits and risks of prolonged dual antiplatelet therapy (DAPT) have not been studied extensively across a broad spectrum of acute coronary syndromes. In this study we investigated whether treatment effects of prolonged DAPT were consistent in patients presenting with ST-segment elevation myocardial infarction (STEMI) vs. non-STEMI (NSTEMI).Methods and Results:As a post hoc analysis of the SMART-DATE trial, effects of ≥12 vs. 6 months DAPT were compared among 1,023 patients presenting with STEMI and 853 NSTEMI patients. The primary outcome was a composite of recurrent myocardial infarction (MI) or stent thrombosis at 18 months after the index procedure. Compared with the 6-month DAPT group, the rate of the composite endpoint was significantly lower in the ≥12-month DAPT group (1.2% vs. 3.8%; hazard ratio [HR] 0.31, 95% confidence interval [CI] 0.12-0.77; P=0.012). The treatment effect of ≥12- vs. 6-month DAPT on the composite endpoint was consistent among NSTEMI patients (0.2% vs. 1.2%, respectively; HR 0.20, 95% CI 0.02-1.70; P=0.140; Pinteraction=0.718). In addition, ≥12-month DAPT increased Bleeding Academic Research Consortium (BARC) Type 2-5 bleeding among both STEMI (4.4% vs. 2.0%; HR 2.18, 95% CI 1.03-4.60; P=0.041) and NSTEMI (5.1% vs. 2.2%; HR 2.37, 95% CI 1.08-5.17; P=0.031; Pinteraction=0.885) patients. CONCLUSIONS Compared with 6-month DAPT, ≥12-month DAPT reduced recurrent MI or stent thrombosis regardless of the type of MI at presentation.

Abstract
Coronary bifurcations exhibit localised turbulent flow and an enhanced propensity for atherothrombosis, platelet deposition and plaque rupture. Percutaneous coronary intervention (PCI) of bifurcation lesions is associated with an increased risk of thrombotic events. Such risk is modulated by anatomical complexity, intraprocedural factors and pharmacological therapy. There is no consensus on the appropriate PCI strategy or the optimal regimen and duration of antithrombotic treatment in order to decrease the risk of ischaemic and bleeding complications in the setting of coronary bifurcation. A uniform therapeutic approach meets a clinical need. The present initiative, promoted by the European Bifurcation Club (EBC), involves opinion leaders from Europe, America, and Asia with the aim of analysing the currently available evidence. Although mainly derived from small dedicated studies, substudies of large trials or from authors' opinions, an algorithm for the optimal management of patients undergoing bifurcation PCI, developed on the basis of clinical presentation, bleeding risk, and intraprocedural strategy, is proposed here.
