RESUMO
BACKGROUND: Patients may prefer percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery, despite heart team recommendations. The outcomes in such patients have not been examined. We sought to examine the results of PCI in patients who were recommended for but declined CABG. METHODS AND RESULTS: Consecutive patients with stable ischemic heart disease and unprotected left main or 3-vessel disease or Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score >22 who underwent PCI after heart team review between 2013 and 2020 were included. Patients were categorized into 3 groups according to heart team recommendations on the basis of appropriate use criteria: (1) PCI-recommended; (2) CABG-eligible but refused CABG (CABG-refusal); and (3) CABG-ineligible. The primary end point was the composite of death, myocardial infarction, or stroke at 1 year. The study included 3687 patients undergoing PCI (PCI-recommended, n=1718 [46.6%]), CABG-refusal (n=1595 [43.3%]), and CABG-ineligible (n=374 [10.1%]). Clinical and procedural risk increased across the 3 groups, with the highest comorbidity burden in CABG-ineligible patients. Composite events within 1 year after PCI occurred in 55 (4.1%), 91 (7.0%), and 41 (14.8%) of patients in the PCI-recommended, CABG-refusal, and CABG-ineligible groups, respectively. After multivariable adjustment, the risk of the primary composite outcome was significantly higher in the CABG-refusal (hazard ratio [HR], 1.67 [95% CI, 1.08-3.56]; P=0.02) and CABG-ineligible patients (HR, 3.26 [95% CI, 1.28-3.65]; P=0.004) groups compared with the reference PCI-recommended group, driven by increased death and stroke. CONCLUSIONS: Cardiovascular event rates after PCI were significantly higher in patients with multivessel disease who declined or were ineligible for CABG. Our findings provide real-world data to inform shared decision-making discussions.

INTRODUCTION: To examine risk factors for new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. METHODS: Patients enrolled in the Cardiothoracic Surgical Trials Network multicenter, randomized trial of rate control versus rhythm control for POAF were included. Predictors of POAF were determined using multivariable logistic regression. RESULTS: Among the 2104 patients who were enrolled preoperatively, 695 developed POAF (33.0%). Rates of POAF were 28.1% after isolated coronary artery bypass grafting (CABG), 33.7% after isolated valve repair or replacement, and 47.3% after CABG plus valve repair or replacement. Baseline characteristics associated with an increased risk of POAF identified on multivariable analysis included older age (odds ratio [OR] 1.57; 95% confidence interval [CI] 1.42-1.73, per 10 y), White race or non-Hispanic ethnicity (OR 1.52; CI: 1.11-2.07), history of heart failure (OR 1.55; CI: 1.16-2.08), and history of hypothyroidism (OR 1.42; CI 1.04-1.94). The type of cardiac procedure was associated with an increased risk of POAF with both isolated valve repair or replacement (OR 1.33, CI 1.08-1.64) and combined CABG plus valve repair or replacement (OR 1.64, CI 1.24-2.17) having increased risk of POAF compared to isolated CABG. No preoperative cardiac medication was associated with POAF. CONCLUSIONS: In this prospective cohort of patients, older age, a history of hypothyroidism, a history of heart failure, and valve repair or replacement, with or without CABG, and White non-Hispanic race were associated with an increased risk of POAF.

BACKGROUND: Potent P2Y12 inhibitors such as ticagrelor and prasugrel are superior to clopidogrel in acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI). Whether this benefit extends to a patient population with chronic coronary syndromes (CCS) is unclear. AIMS: We sought to compare the safety and efficacy of prasugrel and ticagrelor versus clopidogrel in patients undergoing PCI for CCS. METHODS: Consecutive patients undergoing PCI for CCS at a tertiary centre between 2014 and 2019 who were discharged on prasugrel or ticagrelor were compared with those on clopidogrel. The primary endpoint was the composite of death and myocardial infarction (MI), with secondary outcomes including rates of bleeding, stroke, and target vessel revascularisation at 1 year. RESULTS: Overall, 11,508 patients were included in the study (ticagrelor/prasugrel n=2,860 [24.9%], clopidogrel n=8,648 [75.1%]) with an increasing frequency of potent P2Y12 inhibitor use over the study period (ptrend<0.001). Clopidogrel was used more frequently in patients with multimorbid risk factors, whereas anatomical or procedural complexity was associated with ticagrelor/prasugrel use (left main PCI, bifurcation PCI, number of lesions, rotational atherectomy). No difference in the incidence of death or MI was noted across the groups (ticagrelor/prasugrel vs clopidogrel: 2.7% vs 3.1%, adjusted hazard ratio [adjHR] 0.86, 95% confidence interval [CI]: 0.62-1.17; p=0.33) or secondary outcomes including bleeding (adjHR 0.75, 95% CI: 0.46-1.21; p=0.23) on propensity score stratification analysis. Additionally, no difference in the primary outcome was observed across subgroups, including those undergoing complex PCI. CONCLUSIONS: Ticagrelor and prasugrel are increasingly used in patients with CCS undergoing PCI with similar 1-year efficacy and safety when compared to clopidogrel. Whether use of these agents can be beneficial in patients undergoing PCI for CCS with a high thrombotic and low bleeding risk warrants further study.

INTRODUCTION: The Seattle Angina Questionnaire (SAQ-7) quantifies the impact of angina on patient functionality and quality of life. There is scarce data on the impact of social determinants and comorbidities on SAQ-7 in patients undergoing percutaneous coronary intervention (PCI) with planned staged PCI. METHODS: Patients completed a SAQ-7 before each PCI. Multivariable regression analysis was performed to study the impact of social determinants, comorbidities, and procedural characteristics on SAQ-7 scores at index PCI and at the time of the staged PCI. RESULTS: 531 patients were studied. Female sex, non-White race, coronary artery bypass graft history (CABG), and chronic lung disease were associated with lower baseline SAQ-7 scores. Overall, SAQ-7 increased between index procedure and staged PCI (11.9 ± 23.4). Body mass index (BMI) and the treatment of bifurcation lesions were independently associated with improvement of SAQ-7 between PCIs. Post-intervention, neither sex nor race was independently associated with changes in SAQ-7 scores. CONCLUSION: Different disparities and comorbid factors affect SAQ-7 before and after PCI. After revascularization, sex and race were not independent predictors of SAQ-7 improvement.

AIMS: Complex percutaneous coronary intervention (C-PCI) is associated with an increased risk of ischaemic and bleeding complications. We aimed to assess the safety and efficacy of a 1-3-month dual antiplatelet therapy (DAPT) regimen followed by P2Y12 inhibitor monotherapy after C-PCI. METHODS AND RESULTS: We conducted a meta-analysis of randomized trials comparing a 1-3-month DAPT regimen followed by P2Y12 inhibitor monotherapy with standard (≥12 months) DAPT in patients undergoing C-PCI. C-PCI criteria and the co-primary bleeding and ischaemic outcomes were determined according to each trial. Secondary outcomes included major bleeding, all-cause death, myocardial infarction, and stent thrombosis. All outcomes were evaluated at 12 months after randomization. We used hazard ratios (HRs) and 95% confidence interval (CI) as a metric of choice for treatment effects with random-effects models. Among 8299 screened studies, five randomized trials fulfilled the eligibility criteria. In the pooled population of 34 615 patients, 8818 (25.5%) underwent C-PCI. As compared with standard DAPT, a 1-3-month DAPT regimen followed by P2Y12 inhibitor monotherapy reduced the bleeding risk in C-PCI (HR:0.66, 95% CI:0.44-0.98) and non-C-PCI (HR:0.60, 95% CI:0.45-0.79) patients (P-interaction = 0.735). Furthermore, the risk for the primary ischaemic endpoint was similar in patients randomized to either arm, with significant effect modification by PCI complexity showing an enhanced benefit of 1-3-month DAPT in patients undergoing C-PCI (C-PCI, HR:0.69, 95% CI:0.48-1.00; non-C-PCI, HR:1.04, 95% CI:0.84-1.30; P-interaction = 0.028). CONCLUSION: As compared with a standard DAPT, a 1-3-month DAPT regimen followed by P2Y12 inhibitor monotherapy reduced bleeding complications after C-PCI without increasing the risk of ischaemic events.PROSPERO-registered (CRD42021259271).

BACKGROUND: The optimal perioperative management of antiplatelet therapy (APT) therapy in patients undergoing noncardiac surgery (NCS) following percutaneous coronary intervention (PCI) is unclear. We sought to identify predictors of APT cessation in a real-world cohort of patients undergoing NCS within 1 year of PCI. METHODS: Consecutive patients undergoing PCI at a tertiary center between 2011 and 2018 were prospectively enrolled. Perioperative interruption of APT was defined as cessation of either aspirin or P2Y12 inhibitor between 1 and 14 days prior to NCS. Predictors of APT discontinuation were identified by multivariable Cox regression with stepwise selection of candidate variables. RESULTS: A total of 1092 surgeries corresponding to 747 patients were identified. Overall, there were 487 (44.6%) preoperative antiplatelet interruptions: discontinuation of either P2Y12 inhibitors only (47.4%), aspirin only (7.9%), or both agents (44.7%). Both patient-specific risk factors (prior stroke, lower BMI, anemia, MI) and procedure specific risk factors (chronic total occlusions, multivessel disease, drug-eluting stent use) affected decisions regarding APT cessation. Likelihood of APT cessation increased in higher-risk surgeries and in patients on more potent P2Y12 inhibitors (ticagrelor/prasugrel vs clopidogrel) whereas those undergoing NCS <90 days post PCI were less likely to have cessation of APT. CONCLUSION: In this contemporary cohort of post-PCI patients undergoing NCS, patient-, angiographic- and surgery-specific factors all affected decision-making regarding APT cessation. Our findings reflective of real-world practice, highlight the importance of a multidisciplinary team approach to individualize decision making in these patients.

Biological and sociocultural differences between men and women are complex and likely account for most of the variations in the epidemiology and treatment outcomes of coronary artery disease (CAD) between the 2 sexes. Worse outcomes in women have been described following both conservative and invasive treatments of CAD. For example, increased levels of residual platelet reactivity during treatment with antiplatelet drugs, higher rates of adverse cardiovascular outcomes following percutaneous coronary revascularization, and higher operative and long-term mortality after coronary bypass surgery have been reported in women compared with in men. Despite the growing recognition of sex-specific determinants of outcomes, representation of women in clinical studies remains low and sex-specific management strategies are generally not provided in guidelines. This review summarizes the current evidence on sex-related differences in patients with CAD, focusing on the differential outcomes following medical therapy, percutaneous coronary interventions, and coronary artery bypass surgery.

AIMS: To evaluate the impact of perioperative P2Y12 receptor inhibitor therapy among patients undergoing cardiac surgery within 1 year of percutaneous coronary intervention (PCI). METHODS AND RESULTS: Patients undergoing cardiac surgery in the year post-PCI at three tertiary care centres between 2011 and 2018 were stratified into those who had received at least one dose of P2Y12 inhibitor prior to surgery (within 5 days for clopidogrel or prasugrel, or within 3 days for ticagrelor) and those who had not. The outcomes of interest were major adverse cardiac and cerebrovascular events (MACCEs) and bleeding. Among 20 279 PCI patients, 359 (1.8%) underwent cardiac surgery in the ensuing year, 76.3% of whom received coronary artery bypass grafts. Overall, 33 (9.2%) MACCEs and 85 (23.7%) bleeding events occurred within 30 days post-cardiac surgery. Perioperative P2Y12 inhibition (N = 133, 37%) was not associated with the risk of MACCEs or bleeding, despite numerically lower rates of myocardial infarction or stent thrombosis (0.0% vs. 2.6%; P = 0.089). Patients who continued the P2Y12 inhibitor until the day of surgery (N = 60, 17%) had significantly higher bleeding risk [adjusted odds ratio 2.93, 95% confidence interval 1.53-5.59)]. Predictors of MACCEs included a time interval from PCI to cardiac surgery of ≤30 days and reduced ejection fraction, whereas urgent/emergent surgery predicted bleeding. Chronic kidney disease and myocardial infarction as indication for PCI predicted both MACCEs and bleeding. CONCLUSION: Among patients undergoing cardiac surgery in the year after PCI, the perioperative risk of ischaemic and bleeding events might be influenced by P2Y12 inhibitor therapy in addition to other risk parameters, including the timing and urgency of the procedure.

Background Controversy exists over whether sex has significant interaction with revascularization strategy for unprotected left main coronary artery disease. Higher mortality has been reported among women treated with percutaneous coronary intervention compared with coronary artery bypass grafting. Methods and Results The DELTA (Drug-Eluting Stents for Left Main Coronary Artery Disease) and DELTA-2 registries are international, multicentric registries evaluating the outcomes of subjects undergoing coronary revascularization for unprotected left main coronary artery disease. The primary outcome was a composite of death, myocardial infarction, or cerebrovascular accidents. The population consisted of 6253 patients, including 1689 (27%) women. Women were older and more likely to have diabetes and chronic kidney disease than men (P<0.05). At a median follow-up of 29 months (interquartile range 12-49), a significant interaction between sex and revascularization strategy was observed for the primary end point (pint=0.012) and all-cause death (pint=0.037). Among women, compared with percutaneous coronary intervention, coronary artery bypass grafting was associated with lower risk of the primary end point (event rate 9.5% versus 15.3%; adjusted hazard ratio [AHR], 0.53; 95% CI, 0.35-0.79, P<0.001) and all-cause death (event rate 5.6% versus 11.7% AHR, 0.50; 95% CI, 0.30-0.82) and no significant differences were observed in men. Conclusions In women undergoing coronary revascularization for unprotected left main coronary artery disease, coronary artery bypass grafting was associated with lower risk of death, myocardial infarction, or cerebrovascular accidents whereas no significant differences between coronary artery bypass grafting and percutaneous coronary intervention were observed in men. Further dedicated studies are needed to determine the optimal revascularization strategy in women with unprotected left main coronary artery disease.

COVID-19 affects multiple organs. Clinical data from the Mount Sinai Health System show that substantial numbers of COVID-19 patients without prior heart disease develop cardiac dysfunction. How COVID-19 patients develop cardiac disease is not known. We integrated cell biological and physiological analyses of human cardiomyocytes differentiated from human induced pluripotent stem cells (hiPSCs) infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the presence of interleukins (ILs) with clinical findings related to laboratory values in COVID-19 patients to identify plausible mechanisms of cardiac disease in COVID-19 patients. We infected hiPSC-derived cardiomyocytes from healthy human subjects with SARS-CoV-2 in the absence and presence of IL-6 and IL-1ß. Infection resulted in increased numbers of multinucleated cells. Interleukin treatment and infection resulted in disorganization of myofibrils, extracellular release of troponin I, and reduced and erratic beating. Infection resulted in decreased expression of mRNA encoding key proteins of the cardiomyocyte contractile apparatus. Although interleukins did not increase the extent of infection, they increased the contractile dysfunction associated with viral infection of cardiomyocytes, resulting in cessation of beating. Clinical data from hospitalized patients from the Mount Sinai Health System show that a significant portion of COVID-19 patients without history of heart disease have elevated troponin and interleukin levels. A substantial subset of these patients showed reduced left ventricular function by echocardiography. Our laboratory observations, combined with the clinical data, indicate that direct effects on cardiomyocytes by interleukins and SARS-CoV-2 infection might underlie heart disease in COVID-19 patients. IMPORTANCE SARS-CoV-2 infects multiple organs, including the heart. Analyses of hospitalized patients show that a substantial number without prior indication of heart disease or comorbidities show significant injury to heart tissue, assessed by increased levels of troponin in blood. We studied the cell biological and physiological effects of virus infection of healthy human iPSC-derived cardiomyocytes in culture. Virus infection with interleukins disorganizes myofibrils, increases cell size and the numbers of multinucleated cells, and suppresses the expression of proteins of the contractile apparatus. Viral infection of cardiomyocytes in culture triggers release of troponin similar to elevation in levels of COVID-19 patients with heart disease. Viral infection in the presence of interleukins slows down and desynchronizes the beating of cardiomyocytes in culture. The cell-level physiological changes are similar to decreases in left ventricular ejection seen in imaging of patients' hearts. These observations suggest that direct injury to heart tissue by virus can be one underlying cause of heart disease in COVID-19.

OBJECTIVES: To evaluate and compare characteristics and clinical outcomes of percutaneous coronary intervention (PCI) among target vessel types in patients with a prior coronary artery bypass graft (CABG) surgery. BACKGROUND: Patients with a prior CABG often require repeat revascularization with PCI. Graft PCI has been associated with worse outcomes compared to native vessel PCI, yet the optimal PCI strategy in prior CABG patients remains unknown. METHODS: We stratified prior CABG patients who underwent PCI at a tertiary-care center between 2009 and 2017 by target vessel type: native vessel, venous graft, and arterial graft. The primary outcome of major adverse cardiac events (MACE) was a composite of all-cause death, myocardial infarction, stent thrombosis, or target vessel revascularization up to 1 year post-PCI. RESULTS: Prior CABG patients (n = 3983) represented 19.5% of all PCI interventions during the study period. PCI was most frequently performed on native vessels (n = 2928, 73.5%) followed by venous (n = 883, 22.2%) and arterial grafts (n = 172, 4.3%). Procedural success and complications were similar among the groups; however, slow- and no-reflow phenomenon was more common in venous graft PCI compared to native vessel PCI (OR 4.78; 95% CI 2.56-8.95; p < 0.001). At 1 year, there were no significant differences in MACE or in its individual components. CONCLUSIONS: Target vessel choice did not appear to affect MACE at 1 year in a large cohort of patients with prior CABG undergoing PCI. Whether PCI of surgical grafts versus native arteries truly results in similar outcomes warrants further investigation in randomized controlled trials.

BACKGROUND: Whether to repair nonsevere tricuspid regurgitation (TR) during surgery for ischemic mitral valve regurgitation (IMR) remains uncertain. OBJECTIVES: The goal of this study was to investigate the incidence, predictors, and clinical significance of TR progression and presence of ≥moderate TR after IMR surgery. METHODS: Patients (n = 492) with untreated nonsevere TR within 2 prospectively randomized IMR trials were included. Key outcomes were TR progression (either progression by ≥2 grades, surgery for TR, or severe TR at 2 years) and presence of ≥moderate TR at 2 years. RESULTS: Patients' mean age was 66 ± 10 years (67% male), and TR distribution was 60% ≤trace, 31% mild, and 9% moderate. Among 2-year survivors, TR progression occurred in 20 (6%) of 325 patients. Baseline tricuspid annular diameter (TAD) was not predictive of TR progression. At 2 years, 37 (11%) of 323 patients had ≥moderate TR. Baseline TR grade, indexed TAD, and surgical ablation for atrial fibrillation were independent predictors of ≥moderate TR. However, TAD alone had poor discrimination (area under the curve, ≤0.65). Presence of ≥moderate TR at 2 years was higher in patients with MR recurrence (20% vs. 9%; p = 0.02) and a permanent pacemaker/defibrillator (19% vs. 9%; p = 0.01). Clinical event rates (composite of ≥1 New York Heart Association functional class increase, heart failure hospitalization, mitral valve surgery, and stroke) were higher in patients with TR progression (55% vs. 23%; p = 0.003) and ≥moderate TR at 2 years (38% vs. 22%; p = 0.04). CONCLUSIONS: After IMR surgery, progression of unrepaired nonsevere TR is uncommon. Baseline TAD is not predictive of TR progression and is poorly discriminative of ≥moderate TR at 2 years. TR progression and presence of ≥moderate TR are associated with clinical events.

OBJECTIVES: Two trials (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation Trial and Percutaneous Repair with the MitraClip Device for Severe Functional/Secondary Mitral Regurgitation Trial) were published in 2018 evaluating the effectiveness and safety of transcatheter repair for patients with heart failure with significant functional mitral regurgitation, which yielded different results. This article reviews the strength of the evidence, differences in trial designs, ethical and implementation implications, and delineates future research needs to help guide the appropriate dissemination of transcatheter repair for functional patients with mitral regurgitation. METHODS: The National Heart, Lung, and Blood Institute convened a workshop of interdisciplinary experts to address these objectives. RESULTS: Transcatheter repair of functional mitral regurgitation can provide significant benefits in terms of heart failure hospitalizations, survival, and quality of life when appropriate heart failure candidates with moderate to severe or severe mitral regurgitation while on optimal guideline-directed medical therapy can be identified. Key ingredients for success are preoperative evaluation and management and postoperative care by an interdisciplinary heart team. CONCLUSIONS: Given the discordance observed between trials, ongoing innovation in patient management, and potential expansion of indications for use, the evidence base must be expanded to optimize appropriate implementation of this complex therapy. This will require more complete capture of outcome data in real-world settings for all eligible candidates whether or not they receive this therapy. Inevitably, the indications for use of this therapy will expand, as will the devices and therapeutic approaches for this population, necessitating the study of comparative effectiveness through randomized trials or observational studies. Moreover, given the substantial variations in care delivery, conducting implementation research to delineate characteristics of the optimal care model would be of benefit.

OBJECTIVE: The dissemination of mitral valve repair as the first-line treatment and the introduction of MitraClip for patients who have a prohibitive risk for surgery have changed the landscape of mitral valve intervention. The aim of this study is to provide current and generalizable data regarding the trend of mitral valve interventions and outcomes from 2000 to 2016. METHODS: Patients ≥18 years of age who underwent mitral-valve interventions were identified using the National Inpatient Sample database. National estimates were generated by means of discharge weights; comorbid conditions were identified using Elixhauser methods. All trends were analyzed with JoinPoint software. RESULTS: A total of 656,030 mitral valve interventions (298,102 mitral valve replacement, 349,053 mitral valve repair, and 8875 MitraClip) were assessed. No changes in rate of procedures (per 100,000 people in the United States) were observed over this period (annual percent change, -0.4; 95% confidence limit, -1.1 to 0.3; P = .3). From 2000 to 2010, the number of replacements decreased by 5.6% per year (P < .001), whereas repair increased by 8.4% per year from 2000 to 2006 (P < .001). MitraClip procedures increased by 84.4% annually from 2013 to 2016 (P < .001). The burden of comorbidities increased throughout the study for all groups, with the greatest score for MitraClip recipients. Overall, length of stay has decreased for all interventions, most significantly for MitraClip. In-hospital mortality decreased from 8.5% to 3.7% for all interventions, with MitraClip having the most substantial decrease from 3.6% to 1.5%. CONCLUSIONS: Over a 17-year period, mitral-valve interventions were associated with improved outcomes despite being applied to an increasingly sicker population.

Patients with atrial fibrillation who undergo percutaneous coronary intervention with drug-eluting stent implantation often require oral anticoagulation (OAC) and antiplatelet therapies. Triple antithrombotic therapy (OAC, a P2Y12-receptor inhibitor, and aspirin) has been the default antithrombotic strategy. Evidence from randomized trials indicates, however, that a dual antithrombotic therapy strategy (OAC plus a P2Y12-receptor inhibitor) reduces bleeding risk without increasing the risk of ischemic events. This review provides an overview of advancements in this field as well as European and North American guidelines and consensus documents to inform clinical decision making around antithrombotic therapies for patients with atrial fibrillation who undergo percutaneous coronary intervention.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) who develop cardiac injury are reported to experience higher rates of malignant cardiac arrhythmias. However, little is known about these arrhythmias-their frequency, the underlying mechanisms, and their impact on mortality. METHODS: We extracted data from a registry (NCT04358029) regarding consecutive inpatients with confirmed COVID-19 who were receiving continuous telemetric ECG monitoring and had a definitive disposition of hospital discharge or death. Between patients who died versus discharged, we compared a primary composite end point of cardiac arrest from ventricular tachycardia/fibrillation or bradyarrhythmias such as atrioventricular block. RESULTS: Among 800 patients with COVID-19 at Mount Sinai Hospital with definitive dispositions, 140 patients had telemetric monitoring, and either died (52) or were discharged (88). The median (interquartile range) age was 61 years (48-74); 73% men; and ethnicity was White in 34%. Comorbidities included hypertension in 61%, coronary artery disease in 25%, ventricular arrhythmia history in 1.4%, and no significant comorbidities in 16%. Compared with discharged patients, those who died had elevated peak troponin I levels (0.27 versus 0.02 ng/mL) and more primary end point events (17% versus 4%, P=0.01)-a difference driven by tachyarrhythmias. Fatal tachyarrhythmias invariably occurred in the presence of severe metabolic imbalance, while atrioventricular block was largely an independent primary event. CONCLUSIONS: Hospitalized patients with COVID-19 who die experience malignant cardiac arrhythmias more often than those surviving to discharge. However, these events represent a minority of cardiovascular deaths, and ventricular tachyarrhythmias are mainly associated with severe metabolic derangement.

BACKGROUND: Whether a regimen of ticagrelor monotherapy attenuates bleeding complications without increasing ischemic risk in patients undergoing complex percutaneous coronary intervention (PCI) is unknown. OBJECTIVES: The purpose of this study was to evaluate the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients undergoing complex PCI from the randomized, double-blind, placebo-controlled TWILIGHT (Ticagrelor with Aspirin or Alone in High-Risk Patients after Coronary Intervention) trial. METHODS: In the TWILIGHT trial, after 3 months of ticagrelor plus aspirin, event-free and adherent patients remained on ticagrelor and were randomly assigned to receive aspirin or placebo for 1 year. Complex PCI was defined as any of the following: 3 vessels treated, ≥3 lesions treated, total stent length >60 mm, bifurcation with 2 stents implanted, atherectomy device use, left main PCI, surgical bypass graft or chronic total occlusion as target lesions. Bleeding and ischemic endpoints were evaluated at 1 year after randomization. RESULTS: Among 7,119 patients randomized in the main trial, complex PCI was performed in 2,342 patients. Compared to ticagrelor plus aspirin, ticagrelor plus placebo resulted in significantly lower rates of Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding (4.2% vs. 7.7%; hazard ratio [HR]: 0.54; 95% confidence interval [CI]: 0.38 to 0.76). BARC type 3 or 5 bleeding was also significantly reduced (1.1% vs. 2.6%; HR: 0.41; 95% CI: 0.21 to 0.80). There were no significant between-group differences in death, myocardial infarction, or stroke (3.8% vs. 4.9%; HR: 0.77; 95% CI: 0.52 to 1.15), nor in stent thrombosis. CONCLUSIONS: Among patients undergoing complex PCI who initially completed 3 months of ticagrelor plus aspirin, continuation of ticagrelor monotherapy was associated with lower incidence of bleeding without increasing the risk of ischemic events compared to continuing ticagrelor plus aspirin.
