RESUMEN
BACKGROUND: Concomitant use of clopidogrel and proton pump inhibitor (PPI) is common, but PPI may reduce the antiplatelet effects of clopidogrel in patients undergoing percutaneous coronary intervention (PCI). We evaluated the impact of PPI use on clinical outcomes in post-PCI patients, by incorporating P2Y12 reaction unit (PRU) and CYP2C19 genotyping results. METHODS: From a multicenter registry of patients who underwent PCI with drug-eluting stent implantation and received clopidogrel-based dual antiplatelet therapy (DAPT), patients who were prescribed a PPI at the time of PCI (PPI users) were compared to those who were not (non-users). The primary outcome included all-cause death, myocardial infarction, stent thrombosis, or cerebrovascular accident at 12 months. Major bleeding (Bleeding Academic Research Consortium [BARC] types 3-5) and gastrointestinal (GI) bleeding (BARC types 3-5) were important secondary outcomes. The adjusted outcomes were compared using a 1:1 propensity-score (PS) matching and competing risk analysis. RESULTS: Of 13,160 patients, 2,235 (17.0%) were prescribed PPI, with an average age of 65.4 years. PPI users had higher on-treatment PRU levels than non-users. After PS matching, the primary outcome occurred in 51 patients who were PPI users (cumulative incidence, 4.7%) and 41 patients who were non-users (cumulative incidence, 3.7%; log-rank p = 0.27). In carriers of both CYP2C19 loss-of-function alleles, PPI use was linked to an increased risk of the primary outcome (hazard ratio, 3.22; 95% confidence interval, 1.18-8.78). The incidence of major bleeding and GI bleeding (BARC types 3-5) was comparable between PPI users and non-users in the PS-matched cohort. CONCLUSIONS: In post-PCI patients receiving clopidogrel-based DAPT, PPI use was not linked to an increased risk of adverse cardiac and cerebrovascular events, but there was a small but significant increase in on-treatment PRU. Future research using a more individualized approach would further elucidate these interactions and guide evidence-based clinical practices.

BACKGROUND: Whether angiotensin II receptor blocker (ARB) can be an alternative to angiotensin-converting enzyme inhibitor (ACEI) in patients without heart failure (HF) after acute myocardial infarction (MI) remains controversial. The aim of this study was to compare clinical outcomes between initial ARB and ACEI therapy in patients with MI without HF. METHODS: Between 2010 and 2016, a total of 31,013 patients who underwent coronary revascularization for MI with prescription of ARB or ACEI at hospital discharge were enrolled from the Korean nationwide medical insurance data. Patients who had HF at index MI were excluded. The primary outcome was all-cause death. The secondary outcomes included recurrent MI, hospitalization for new heart HF, stoke, and a composite of each outcome. RESULTS: Of 31,013 patients, ARBs were prescribed in 12,685 (40.9%) and ACEIs in 18,328 (59.1%). Patients receiving ARB had a lower discontinuation rate compared with those receiving ACEI (28.2% versus 43.5%, adjusted hazard ratio [HR] 0.34, 95% confidence interval [CI] 0.31-0.37, p<0.01). During a median follow-up of 2.2 years, 2,480 patients died. The incidence rate of all-cause death in patients receiving ARB and those receiving ACEI was 27.7 and 22.9 per 1,000 person-years, respectively (adjusted HR 1.04; 95% CI, 0.95-1.13; p=0.40). There were no significant differences in the secondary outcomes between patients receiving ARB and those receiving ACEI, except stroke (19.2 vs. 13.6 per 1,000 person-years; adjusted HR 1.17; 95% CI 1.04-1.32; p=0.01). In a subgroup analysis, a higher mortality was observed with ARBs compared to ACEIs in patients with diabetes. CONCLUSIONS: In this nationwide cohort, there was no significant difference in the incidence of all-cause death between ARB and ACEI as discharge medications in patients with MI without HF. ARBs would be an alternative to ACEIs for those intolerant to ACEI therapy.
RESUMEN
We investigated the long-term patterns and effects of transfusion on the clinical outcome of patients undergoing percutaneous coronary intervention (PCI) using a nationwide registry. Five-year clinical outcome of all Koreans undergoing PCI using stent in year 2011 (n = 48,786) was investigated. Primary outcome was the incidence density of transfusion. The association of transfusion with major adverse clinical event (MACE) consisting all-cause death, revascularization, critically ill cardiovascular status, or stroke was assessed after adjusting the propensity of each patient for transfusion. The 5-year incidence density of transfusion was 4.74 (95% confidence interval [CI] 4.70-4.79) per 100 person-year. Patients who received transfusion were older and had higher frequency of clinical risk factors (p < 0.001, all). Transfusion was associated with MACE (hazard ratio [HR] 3.2, 95% CI 3.2-3.3, p < 0.001) and all other clinical events (HR 1.5-6.9, p < 0.001, all). The period of transfusion coincided with the period of highest MACE incidence density. Subgroup analyses showed consistent results. Within 5 years after PCI, a total of 22.9% of patients received transfusion and had a 3.2-fold higher risk of MACE compared to patients without transfusion.

Background: There are limited clinical data on drug-coated balloon (DCB)-based percutaneous coronary intervention (PCI) compared with drug-eluting stent (DES)-only PCI in patients with complex coronary artery lesions. Objectives: The goal of the current study was to investigate the efficacy of DCB in patients undergoing PCI for complex coronary artery lesions. Methods: From an institutional registry of patients with de novo complex coronary artery lesions, 126 patients treated with DCB-based PCI were compared with 234 propensity score-matched patients treated with DES-only PCI. Complex coronary artery lesions were defined as the presence of at least 1 of the following: bifurcation, chronic total occlusion, unprotected left main disease, long lesion ≥38 mm, multivessel disease, lesion requiring ≥3 devices, or severe calcification. The primary endpoint was target vessel failure (TVF) at 2 years, a composite of cardiac death, target vessel-related myocardial infarction, and target vessel revascularization. Results: Baseline characteristics were comparable between the 2 groups. DCB-based PCI showed a comparable risk of TVF vs DES-based PCI (7.6% vs 8.1%; HR: 0.81; 95% CI: 0.33-1.99; P = 0.638). The risks of cardiac death (5.0% vs 5.7%; HR: 0.78; 95% CI: 0.24-2.49), target vessel-related myocardial infarction (0.9% vs 1.3%; HR: 2.65; 95% CI: 0.26-27.06), and target vessel revascularization (3.5% vs 2.0%; HR: 1.30; 95% CI: 0.30-5.67) were also comparable between the 2 groups. Conclusions: DCB-based PCI showed comparable risks of TVF vs those of DES-only PCI in patients with complex coronary artery lesions. DCB might be considered as a suitable alternative device to DES in patients undergoing complex PCI. (Long-term Outcomes and Prognostic Factors in Patient Undergoing CABG or PCI; NCT03870815).
RESUMEN
BACKGROUND: Currently, non-vitamin K-antagonist oral anticoagulant (NOAC) monotherapy has been suggested as the optimal antithrombotic therapy for atrial fibrillation (AF) beyond one year after coronary revascularization. The aim of this study was to compare the outcomes between NOAC monotherapy and NOAC plus antiplatelet combination therapy using real-world data. METHODS: Between 2015 and 2020, patients with AF who had received NOACs beyond one year after coronary revascularization were enrolled from Korean national insurance data. We emulated a pragmatic sequence of trials between the NOAC monotherapy and the antiplatelet combination therapy followed by propensity score matching. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCEs), a composite of all-cause death, myocardial infarction, and stroke. RESULTS: Among 206,407 person-trials from 4,465 individuals, we compared 3,275 pairs of the monotherapy and the matched combination therapy. During a median follow-up of 1.24 years, the incidence rate of MACCE was 19.4% and 20.0% per patient-year in the monotherapy group and the antiplatelet combination group, respectively (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.88-1.05; P = 0.422). Compared with the antiplatelet combination group, the monotherapy group had a significantly lower incidence rate of major bleeding, defined as intracranial bleeding or gastrointestinal bleeding requiring hospitalization (2.8% vs. 3.6% per patient-year; HR, 0.78; 95% CI, 0.62-0.97; P = 0.024). CONCLUSION: As an antithrombotic therapy for AF beyond one year after coronary revascularization, NOAC monotherapy was associated with a similar risk of MACCE and a lower risk of major bleeding compared to NOAC plus antiplatelet combination therapy.

Importance: Data are limited regarding the effects of intravascular imaging guidance during complex percutaneous coronary intervention (PCI) in patients with diabetes. Objective: To compare the clinical outcomes of intravascular imaging-guided vs angiography-guided complex PCI in patients with or without diabetes. Design, Setting, and Participants: This prespecified secondary analysis of a subgroup of patients in RENOVATE-COMPLEX-PCI (Randomized Controlled Trial of Intravascular Imaging Guidance Versus Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention), an investigator-initiated, open-label multicenter trial, analyzed enrolled patients who underwent complex PCI at 20 sites in Korea from May 2018 through May 2021. Eligible patients were randomly assigned in a 2:1 ratio to undergo either the intravascular imaging-guided PCI or angiography-guided PCI. Data analyses were performed from June 2023 to April 2024. Interventions: Percutaneous coronary intervention was performed either under the guidance of intravascular imaging or angiography alone. Main Outcomes and Measures: The primary end point was target vessel failure (TVF), defined as a composite of cardiac death, target vessel-related myocardial infarction, or target vessel revascularization. Results: Among the 1639 patients included in the analysis (mean [SD] age, 65.6 [10.2] years; 1300 males [79.3%]), 617 (37.6%) had diabetes. The incidence of TVF was significantly higher in patients with diabetes than patients without diabetes (hazard ratio [HR], 1.86; 95% CI, 1.33-2.60; P < .001). Among patients without diabetes, the intravascular imaging-guided PCI group had a significantly lower incidence of TVF compared with the angiography-guided PCI group (4.7% vs 12.2%; HR, 0.41 [95% CI, 0.25-0.67]; P < .001). Conversely, in patients with diabetes, the risk of TVF was not significantly different between the 2 groups (12.9% vs 12.3%; HR, 0.97 [95% CI, 0.60-1.57]; P = .90). There was a significant interaction between the use of intravascular imaging and diabetes for the risk of TVF (P for interaction = .02). Among patients with diabetes, only those with good glycemic control (hemoglobin A1c level ≤7.5%) and who achieved stent optimization by intravascular imaging showed a lower risk of future ischemic events (HR, 0.31; 95% CI, 0.12-0.82; P = .02). Conclusions and Relevance: In this secondary analysis of a subgroup of patients in the RENOVATE-COMPLEX-PCI trial, intravascular imaging guidance reduced the risk of TVF compared with angiography guidance in patients without diabetes (but not in patients with diabetes) during complex PCI. In patients with diabetes undergoing complex PCI, attention should be paid to stent optimization using intravascular imaging and glycemic control to improve outcomes.

AIMS: This study sought to examine the difference in clinical characteristics, treatment strategy, trends in mortality, and medical costs according to the aetiologies of cardiogenic shock (CS). METHODS AND RESULTS: This was a population-based, nationwide, cohort study from the Korean National Health Insurance Service database. All CS adults (≥18 years) were admitted to an intensive care unit from January 2010 to December 2020. The primary outcome was in-hospital mortality. The secondary outcomes were cardiac replacement therapy (left ventricular assisted device implantation or heart transplantation), all-cause mortality, ischaemic stroke, rehospitalization for heart failure (HF) during follow-up, and actual in-hospital medical costs. Among 136 092 individuals with CS, 48 704 (29.7%) cases were due to acute myocardial infarction-related CS (AMI-CS), and the remaining 87 388 (71.3%) were due to HF-CS (ischaemic cardiomyopathy [ICM] vs. non-ICM, 49 504 [56.6%] vs. 37 884 [45.4%]). Patients with HF-CS were older, less likely to be male, and less likely to receive mechanical circulatory support, compared to those with AMI-CS. During the 10-year study period, the in-hospital mortality rate decreased, and actual medical costs tended to increase, regardless of CS aetiology. Compared with AMI-CS, HF-CS was associated with higher risks of in-hospital mortality (40.3% vs. 28.5%; adjusted odds ratio [OR] 1.47, 95% confidence interval [CI] 1.43-1.52), cardiac replacement therapy (adjusted OR 1.65, 95% CI 1.16-2.34), as well as follow-up mortality after successful discharge (19.3% vs. 8.5%; adjusted-hazard ratio 1.54, 95% CI 1.48-1.59). HF-CS had lower medical costs than AMI-CS (adjusted ratio 0.79, 95% CI 0.79-0.80). CONCLUSIONS: With medical advances during the past 10 years, the mortality of CS has decreased significantly, but the mortality of HF-CS remains high. The findings highlight the need for effective treatment strategies for patients with HF-CS.

AIMS: This study evaluated how well serial pulse pressure (PP) and PP adjusted by the vasoactive inotropic score (VIS) predicted venoarterial extracorporeal membrane oxygenation (VA-ECMO) weaning success and clinical outcomes in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) patients. METHODS AND RESULTS: A total of 213 patients with AMI-CS who received VA-ECMO between January 2010 and August 2021 were enrolled in the institutional ECMO registry. Serial PP and VIS were measured immediately, 12, 24, and 48 h after VA-ECMO insertion. PP adjusted by VIS was defined as PP/âVIS. The primary outcome was successful VA-ECMO weaning. Successful weaning from VA-ECMO was observed in 151 patients (70.9%). Immediately after VA-ECMO insertion, PP [successful vs. failed weaning, 26.0 (15.5-46.0) vs. 21.0 (12.5-33.0), P = 0.386] and PP/âVIS [11.1 (5.1-25.0) vs. 6.0 (3.1-14.2), P = 0.118] did not differ between the successful and failed weaning groups. Serial PP and PP adjusted by VIS at 12, 24, and 48 h after VA-ECMO insertion were significantly higher in patients with successful weaning than those with failed weaning [successful vs. failed weaning, 24.0 (4.0-38.0) vs. 12.5 (6.0-25.5), P = 0.007 for 12 h PP, and 10.1 (5.7-22.0) vs. 2.9 (1.7-5.9), P < 0.001 for 12 h PP/âVIS]. The 12 h PP/âVIS showed better discriminative function for successful weaning than 12 h PP alone [area under the curve (AUC) 0.80, 95% confidence interval (CI) 0.72-0.88, P < 0.001 vs. AUC 0.67, 95% CI 0.57-0.77, P = 0.002]. Patients with a low 12 h PP/âVIS (≤7) had higher rates of in-hospital mortality (44.4% vs. 19.8%, P < 0.001) and 6 month follow-up mortality (hazard ratio 2.41, 95% CI 1.49-3.90, P < 0.001) than those with a high 12 h PP/âVIS (>7). CONCLUSIONS: PP adjusted by VIS taken 12 h following VA-ECMO initiation can predict weaning from VA-ECMO more successfully than PP alone, and its low value was associated with a higher risk of mortality in AMI-CS patients.
RESUMEN
This study evaluated the association of atherogenic index of plasma (AIP) with platelet reactivity and clinical outcomes according to acute myocardial infarction (AMI). The composite of 3-year adverse outcomes of all-cause death, myocardial infarction, and cerebrovascular accident was evaluated in 10,735 patients after successful percutaneous coronary intervention with drug-eluting stents. AIP was defined as the base 10 logarithm of the ratio of triglyceride to high-density lipoprotein cholesterol concentration. High platelet reactivity (HPR) was defined as ≥ 252 P2Y12 reactivity unit. An increase of AIP (per-0.1 unit) was related to the decreased risk of HPR [odds ratio (OR) 0.97, 95% confidence interval (CI) 0.96-0.99; P = 0.001] in non-AMI patients, not in AMI patients (OR 0.98, 95% CI 0.96-1.01; P = 0.138). The HPR was associated with the increased risk of composite outcomes in both non-AMI and AMI patients (all-P < 0.05). AIP levels were not independently associated with the risk of composite outcomes in both patients with non-AMI and AMI. In conclusion, an inverse association between AIP and the risk of HPR was observed in patients with non-AMI. This suggests that the association between plasma atherogenicity and platelet reactivity may play a substantial role in the development of AMI.Trial registration: NCT04734028.

AIMS: Although culprit-only revascularization during the index procedure has been recommended in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS), the reduction in residual ischaemia is also emphasized to improve clinical outcomes. However, few data are available about the significance of residual ischaemia in patients undergoing mechanical circulatory supports. This study aimed to evaluate the effects of residual ischaemia on clinical outcomes in patients with AMI undergoing venoarterial-extracorporeal membrane oxygenation (VA-ECMO). METHODS AND RESULTS: Patients with AMI with multivessel disease who underwent VA-ECMO due to refractory CS were pooled from the RESCUE and SMC-ECMO registries. The included patients were classified into three groups according to residual ischaemia evaluated using the residual Synergy between percutaneous coronary intervention with Taxus and Cardiac Surgery (SYNTAX) score (rSS): rSS = 0, 0 < rSS ≤ 8, and rSS > 8. The primary outcome was 1-year all-cause death. A total of 408 patients were classified into the rSS = 0 (n = 100, 24.5%), 0 < rSS ≤ 8 (n = 136, 33.3%), and rSS > 8 (n = 172, 42.2%) groups. The cumulative incidence of the primary outcome differed significantly according to rSS (33.9 vs. 55.4 vs. 66.1% for rSS = 0, 0 < rSS ≤ 8, and rSS > 8, respectively, overall P < 0.001). In a multivariable model, rSS was independently associated with the risk of 1-year all-cause death (adjusted hazard ratio 1.03, 95% confidence interval 1.01-1.05, P = 0.003). Conversely, the baseline SYNTAX score was not associated with the risk of the primary outcome. Furthermore, when patients were stratified by rSS, the primary outcome did not differ significantly between the high and low delta SYNTAX score groups. CONCLUSION: In patients with AMI with refractory CS who underwent VA-ECMO, residual ischaemia was associated with an increased risk of 1-year mortality. Future studies are needed to evaluate the efficacy and safety of revascularization strategies to minimize residual ischaemia in patients with CS supported with VA-ECMO.

BACKGROUND: The Murray law-based quantitative flow ratio (µFR) is an emerging technique that requires only 1 projection of coronary angiography with similar accuracy to quantitative flow ratio (QFR). However, it has not been validated for the evaluation of noninfarct-related artery (non-IRA) in acute myocardial infarction (AMI) settings. Therefore, our study aimed to evaluate the diagnostic accuracy of µFR and the safety of deferring non-IRA lesions with µFR >0.80 in the setting of AMI. METHODS: µFR and QFR were analyzed for non-IRA lesions of patients with AMI enrolled in the FRAME-AMI trial (Fractional Flow Reserve Versus Angiography-Guided Strategy for Management of Non-Infarction Related Artery Stenosis in Patients With Acute Myocardial Infarction), consisting of fractional flow reserve (FFR)-guided percutaneous coronary intervention and angiography-guided percutaneous coronary intervention groups. The diagnostic accuracy of µFR was compared with QFR and FFR. Patients were classified by the non-IRA µFR value of 0.80 as a cutoff value. The primary outcome was a vessel-oriented composite outcome, a composite of cardiac death, non-IRA-related myocardial infarction, and non-IRA-related repeat revascularization. RESULTS: µFR and QFR analyses were feasible in 443 patients (552 lesions). µFR showed acceptable correlation with FFR (R=0.777; P<0.001), comparable C-index with QFR to predict FFR ≤0.80 (µFR versus QFR: 0.926 versus 0.961, P=0.070), and shorter total analysis time (mean, 32.7 versus 186.9 s; P<0.001). Non-IRA with µFR >0.80 and deferred percutaneous coronary intervention had a significantly lower risk of vessel-oriented composite outcome than non-IRA with performed percutaneous coronary intervention (3.4% versus 10.5%; hazard ratio, 0.37 [95% CI, 0.14-0.99]; P=0.048). CONCLUSIONS: In patients with multivessel AMI, µFR of non-IRA showed acceptable diagnostic accuracy comparable to that of QFR to predict FFR ≤0.80. Deferred non-IRA with µFR >0.80 showed a lower risk of vessel-oriented composite outcome than revascularized non-IRA.

BACKGROUND: It is unclear whether the beneficial effects of intravascular imaging-guided stent optimization vary by clinical presentation during complex percutaneous coronary intervention (PCI). OBJECTIVES: In this prespecified, stratified subgroup analysis from RENOVATE-COMPLEX-PCI (Randomized Controlled Trial of Intravascular Imaging Guidance versus Angiography-Guidance on Clinical Outcomes After Complex PCI), we sought to compare the outcomes between intravascular imaging vs angiography guidance according to clinical presentation. METHODS: Patients with complex coronary artery lesions were randomly assigned to undergo either intravascular imaging-guided PCI or angiography-guided PCI in a 2:1 ratio. The primary endpoint was target vessel failure (TVF), which is a composite of cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization. RESULTS: Of 1,639 patients, 832 (50.8%) presented with acute coronary syndrome (ACS) and 807 (49.2%) with chronic coronary syndrome. During a median follow-up of 2.1 years (Q1-Q3: 1.4-3.0 years), there was no significant interaction between the treatment effect of intravascular imaging and clinical presentation (P for interaction = 0.19). Among patients with ACS, the incidences of TVF were 10.4% in the intravascular imaging group and 14.6% in the angiography group (HR: 0.74; 95% CI: 0.48-1.15; P = 0.18). Among patients with CCS, the incidences of TVF were 5.0% in the intravascular imaging group and 10.4% in the angiography group (HR: 0.46; 95% CI: 0.27-0.80; P = 0.006). Achieving stent optimization by intravascular imaging resulted in a reduced risk of TVF among patients with ACS who were randomly assigned to intravascular imaging-guided PCI for complex coronary lesions (optimized vs unoptimized, 6.5% vs 14.1%; HR: 0.49; 95% CI: 0.27-0.87; P = 0.02) but not those with CCS (5.4% vs 4.7%, HR: 1.18; 95% CI: 0.53-2.59; P = 0.69). CONCLUSIONS: No significant interaction was observed between the benefits of intravascular imaging and clinical presentation in the risk of TVF. Stent optimization by intravascular imaging was particularly important for ACS patients.

BACKGROUND: Carriers of CYP2C19 loss-of-function alleles have increased adverse events after percutaneous coronary intervention, but limited data are available for older patients. We aimed to evaluate the prognostic impact of CYP2C19 genotypes on clinical outcomes in older patients after percutaneous coronary intervention. METHODS AND RESULTS: The study included 1201 older patients (aged ≥75 years) who underwent percutaneous coronary intervention and received clopidogrel-based dual antiplatelet therapy in South Korea. Patients were grouped on the basis of CYP2C19 genotypes. The primary outcome was 3-year major adverse cardiac events, defined as a composite of cardiac death, myocardial infarction, and stent thrombosis. Older patients were grouped into 3 groups: normal metabolizer (36.6%), intermediate metabolizer (48.1%), and poor metabolizer (15.2%). The occurrence of the primary outcome was significantly different among the groups (3.1, 7.0, and 6.2% in the normal metabolizer, intermediate metabolizer, and poor metabolizer groups, respectively; P=0.02). The incidence rate of all-cause death at 3 years was greater in the intermediate metabolizer and poor metabolizer groups (8.1% and 9.2%, respectively) compared with that in the normal metabolizer group (3.5%, P=0.03) without significant differences in major bleeding. In the multivariable analysis, the intermediate metabolizer and poor metabolizer groups were independent predictors of 3-year clinical outcomes. CONCLUSIONS: In older patients, the presence of any CYP2C19 loss-of-function allele was found to be predictive of a higher incidence of major adverse cardiac events within 3 years following percutaneous coronary intervention. This finding suggests a need for further investigation into an optimal antiplatelet strategy for older patients. REGISTRATION: URL: https://clinicaltrials.gov. Identifier: NCT04734028.

INTRODUCTION AND OBJECTIVES: The association of revascularization strategy with clinical outcomes according to the ischemic territory of nonculprit lesion has not been documented in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). This study aimed to compare outcomes between culprit-only and immediate multivessel percutaneous coronary intervention (PCI) according to ischemic territory in patients with AMI-CS. METHODS: A total of 536 patients with AMI-CS and multivessel disease from the SMART-RESCUE registry were categorized according to ischemic territory (nonculprit left main/proximal left anterior descending artery [LM/pLAD] vs culprit LM/pLAD vs no LM/pLAD). The primary outcome was a patient-oriented composite endpoint (POCE) consisting of all-cause death, myocardial infarction, rehospitalization due to heart failure, or repeat revascularization at 1 year. RESULTS: Among the total population, 108 patients had nonculprit LM/pLAD, 228 patients had culprit LM/pLAD, and 200 patients had no LM/pLAD, with the risk of POCE being higher in patients with large ischemic territory lesions (53.6% vs 53.4% vs 39.6%; P = .02). Multivessel PCI was associated with a significantly lower risk of POCE compared with culprit-only PCI in patients with nonculprit LM/pLAD (40.7% vs 66.9%; HR, 0.52; 95%CI, 0.29-0.91; P=.02), but not in those with culprit LM/pLAD (P=.46) or no LM/pLAD (P=.47). A significant interaction existed between revascularization strategy and large nonculprit ischemic territory (P=.03). CONCLUSIONS: Large ischemic territory involvement was associated with worse clinical outcomes in patients with AMI-CS and multivessel disease. Immediate multivessel PCI might improve clinical outcomes in patients with a large nonculprit ischemic burden.
RESUMEN
INTRODUCTION AND OBJECTIVES: There are no clinical data on the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI in patients with acute myocardial infarction (AMI) and cardiogenic shock. The current study sought to evaluate the impact of intravascular imaging-guided PCI in patients with AMI and cardiogenic shock. METHODS: Among a total of 28 732 patients from the nationwide pooled registry of KAMIR-NIH (November, 2011 to December, 2015) and KAMIR-V (January, 2016 to June, 2020), we selected a total of 1833 patients (6.4%) with AMI and cardiogenic shock who underwent PCI of the culprit vessel. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of cardiac death, myocardial infarction, repeat revascularization, and definite or probable stent thrombosis. RESULTS: Among the study population, 375 patients (20.5%) underwent intravascular imaging-guided PCI and 1458 patients (79.5%) underwent angiography-guided PCI. Intravascular imaging-guided PCI was associated with a significantly lower risk of 1-year MACE than angiography-guided PCI (19.5% vs 28.2%; HR, 0.59; 95%CI, 0.45-0.77; P<.001), mainly driven by a lower risk of cardiac death (13.7% vs 24.0%; adjusted HR, 0.53; 95%CI, 0.39-0.72; P<.001). These results were consistent in propensity score matching (HR, 0.68; 95%CI, 0.46-0.99), inverse probability weighting (HR, 0.61; 95%CI, 0.45-0.83), and Bayesian analysis (Odds ratio, 0.66, 95% credible interval, 0.49-0.88). CONCLUSIONS: In AMI patients with cardiogenic shock, intravascular imaging-guided PCI was associated with a lower risk of MACE at 1-year than angiography-guided PCI, mainly driven by the lower risk of cardiac death.
RESUMEN
BACKGROUND AND OBJECTIVES: Concerns remain that early aspirin cessation may be associated with potential harm in subsets at high risk of ischemic events. This study aimed to assess the effects of P2Y12 inhibitor monotherapy after 3-month dual antiplatelet therapy (DAPT) vs. prolonged DAPT (12-month or longer) based on the ischemic risk stratification, the CHADS-P2A2RC, after percutaneous coronary intervention (PCI). METHODS: This was a sub-study of the SMART-CHOICE trial. The effect of the randomized antiplatelet strategies was assessed across 3 CHADS-P2A2RC risk score categories. The primary outcome was a major adverse cardiac and cerebral event (MACCE), a composite of all-cause death, myocardial infarction, or stroke. RESULTS: Up to 3 years, the high CHADS-P2A2RC risk score group had the highest incidence of MACCE (105 [12.1%], adjusted hazard ratio [HR], 2.927; 95% confidence interval [CI], 1.358-6.309; p=0.006) followed by moderate-risk (40 [1.4%], adjusted HR, 1.786; 95% CI, 0.868-3.674; p=0.115) and low-risk (9 [0.5%], reference). In secondary analyses, P2Y12 inhibitor monotherapy reduced the Bleeding Academic Research Consortium (BARC) types 2, 3, or 5 bleeding without increasing the risk of MACCE as compared with prolonged DAPT across the 3 CHADS-P2A2RC risk strata without significant interaction term (interaction p for MACCE=0.705 and interaction p for BARC types 2, 3, or 5 bleeding=0.055). CONCLUSIONS: The CHADS-P2A2RC risk score is valuable in discriminating high-ischemic-risk patients. Even in such patients with a high risk of ischemic events, P2Y12 inhibitor monotherapy was associated with a lower incidence of bleeding without increased risk of ischemic events compared with prolonged DAPT.

RESUMEN
BACKGROUND: Although age and body mass index (BMI) significantly affect platelet reactivity units and clinical outcomes after percutaneous coronary intervention, there are limited data on the relationship between high on-treatment platelet reactivity (HPR) and clinical outcomes on age and BMI differences. Thus, we investigated the association of HPR with clinical outcomes according to age and BMI. METHODS AND RESULTS: The study analyzed 11 714 patients who underwent platelet function tests after percutaneous coronary intervention. The primary end point was the occurrence of major adverse cardiac and cerebrovascular events (MACCEs), whereas the secondary end point was major bleeding. HPR was defined as platelet reactivity units ≥252. Patients were categorized by age (<67 years of age or ≥67 years of age) and BMI (≤22.6 kg/m2 or >22.6 kg/m2). Patients <67 years of age with HPR had increases in both MACCEs (adjusted hazard ratio [HR], 1.436 [95% CI, 1.106-1.867]; P=0.007) and major bleeding (adjusted HR, 1.584 [95% CI, 1.095-2.290]; P=0.015) compared with the those with non-HPR, respectively. In patients ≥67 years of age with HPR, there were no differences in MACCEs, but there was a decrease in major bleeding (adjusted HR, 0.721 [95% CI, 0.542-0.959]; P=0.024). Meanwhile, patients with HPR with BMI >22.6 kg/m2 had increases in MACCEs (adjusted HR, 1.387 [95% CI, 1.140-1.688]; P=0.001). No differences were shown in major bleeding. CONCLUSIONS: HPR was linked to an increase in MACCEs or a decrease in major bleeding in patients after percutaneous coronary intervention, depending on age and BMI. This study is the first to observe that clinical outcomes in patients with HPR after percutaneous coronary intervention may vary based on age and BMI. Because the study is observational, the results should be viewed as hypothesis generating and emphasize the need for randomized clinical trials.

Importance: There have been heterogeneous results related to sex differences in prognosis after percutaneous coronary artery intervention (PCI) for complex coronary artery lesions. Objective: To evaluate potential differences in outcomes with intravascular imaging-guided PCI of complex coronary artery lesions between women and men. Design, Setting, and Participants: This prespecified substudy evaluates the interaction of sex in the investigator-initiated, open-label, multicenter RENOVATE-COMPLEX-PCI randomized clinical trial, which demonstrated the superiority of intravascular imaging-guided PCI compared with angiography-guided PCI in patients with complex coronary artery lesions. The trial was conducted at 20 sites in Korea. Patients with complex coronary artery lesions undergoing PCI were enrolled between May 2018 and May 2021, and the median (IQR) follow-up period was 2.1 (1.4-3.0) years. Data were analyzed from December 2022 to December 2023. Interventions: After diagnostic coronary angiography, eligible patients were randomly assigned in a 2:1 ratio to receive intravascular imaging-guided PCI or angiography-guided PCI. The choice and timing of the intravascular imaging device were left to the operators' discretion. Main Outcomes and Measures: The primary end point was target vessel failure, defined as a composite of cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization. Secondary end points included individual components of the primary end point. Results: Of 1639 included patients, 339 (20.7%) were women, and the mean (SD) age was 65.6 (10.2) years. There was no difference in the risk of the primary end point between women and men (9.4% vs 8.3%; adjusted hazard ratio [HR], 1.39; 95% CI, 0.89-2.18; P = .15). Intravascular imaging-guided PCI tended to have lower incidence of the primary end point than angiography-guided PCI in both women (5.2% vs 14.5%; adjusted HR, 0.34; 95% CI, 0.15-0.78; P = .01) and men (8.3% vs 11.7%; adjusted HR, 0.72; 95% CI, 0.49-1.05; P = .09) without significant interaction (P for interaction = .86). Conclusions and Relevance: In patients undergoing complex PCI, compared with angiographic guidance, intravascular imaging guidance was associated with similar reduction in the risk of target vessel failure among women and men. The treatment benefit of intravascular imaging-guided PCI showed no significant interaction between treatment strategy and sex. Trial Registration: ClinicalTrials.gov Identifier: NCT03381872.

BACKGROUND: Limited data exist regarding the prognostic implications of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with non-ST-elevation myocardial infarction (NSTEMI) who undergo percutaneous coronary intervention (PCI). METHODSâANDâRESULTS: Of 13,104 patients in the nationwide Korea Acute Myocardial Infarction Registry-National Institutes of Health, 3,083 patients with NSTEMI who underwent PCI were included in the present study. The primary endpoint was major adverse cardiovascular events (MACE) at 3 years, a composite of all-cause death, recurrent myocardial infarction, unplanned repeat revascularization, and admission for heart failure. NT-proBNP was measured at the time of initial presentation for the management of NSTEMI, and patients were divided into a low (<700 pg/mL; n=1,813) and high (≥700 pg/mL; n=1,270) NT-proBNP group. The high NT-proBNP group had a significantly higher risk of MACE, driven primarily by a higher risk of cardiac death or admission for heart failure. These results were consistent after confounder adjustment by propensity score matching and inverse probability weighting analysis. CONCLUSIONS: In patients with NSTEMI who underwent PCI, an initial elevated NT-proBNP concentration was associated with higher risk of MACE at 3 years, driven primarily by higher risks of cardiac death or admission for heart failure. These results suggest that the initial NT-proBNP concentration may have a clinically significant prognostic value in NSTEMI patients undergoing PCI.

BACKGROUND: Although clinical benefits of intravascular imaging-guided percutaneous coronary intervention (PCI) in patients with complex coronary artery lesions have been observed in previous trials, the cost-effectiveness of this strategy is uncertain. METHODS: RENOVATE-COMPLEX-PCI (Randomized Controlled Trial of Intravascular Imaging Guidance vs Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention) was conducted in Korea between May 2018 and May 2021. This prespecified cost-effectiveness substudy was conducted using Markov model that simulated 3 states: (1) post-PCI, (2) spontaneous myocardial infarction, and (3) death. A simulated cohort was derived from the intention-to-treat population, and input parameters were extracted from either the trial data or previous publications. Cost-effectiveness was evaluated using time horizon of 3 years (within trial) and lifetime. The primary outcome was incremental cost-effectiveness ratio (ICER), an indicator of incremental cost on additional quality-adjusted life years (QALYs) gained, in intravascular imaging-guided PCI compared with angiography-guided PCI. The current analysis was performed using the Korean health care sector perspective with reporting the results in US dollar (1200 Korean Won, â©=1 dollar, $). Willingness to pay threshold was $35 000 per QALY gained. RESULTS: A total of 1639 patients were included in the trial. During 3-year follow-up, medical costs ($8661 versus $7236; incremental cost, $1426) and QALY (2.34 versus 2.31; incremental QALY, 0.025) were both higher in intravascular imaging-guided PCI than angiography-guided PCI, resulting incremental cost-effectiveness ratio of $57 040 per QALY gained within trial data. Conversely, lifetime simulation showed total cumulative medical cost was reversed between the 2 groups ($40 455 versus $49 519; incremental cost, -$9063) with consistently higher QALY (8.24 versus 7.89; incremental QALY, 0.910) in intravascular imaging-guided PCI than angiography-guided PCI, resulting in a dominant incremental cost-effectiveness ratio. Consistently, 70% of probabilistic iterations showed cost-effectiveness of intravascular imaging-guided PCI in probabilistic sensitivity analysis. CONCLUSIONS: The current cost-effectiveness analysis suggests that imaging-guided PCI is more cost-effective than angiography-guided PCI by reducing medical cost and increasing quality-of-life in complex coronary artery lesions in long-term follow-up.
