RESUMO
BACKGROUND: The role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) who subsequently undergo transcatheter aortic valve replacement (TAVR) remains uncertain. Therefore, we conducted this study to assess the association of PCI before TAVR with mortality and cardiovascular outcomes. METHODS: We used the TriNetX database (Jan 2012 - Aug 2022) and grouped patients into PCI (3 months or less) before TAVR and no PCI. We performed propensity score matched (PSM) analyses for outcomes at 30 days and 1 year. RESULTS: Of 17,120 patients undergoing TAVR, 2322 (14 %) had PCI, and 14,798 (86 %) did not have PCI before TAVR. In the PSM cohort (2026 patients in each group), PCI was not associated with lower all-cause mortality at 30 days (HR: 1.25, 95 % CI: 0.82-1.90) or 1 year (HR: 1.02, 95 % CI: 0.83-1.24). Frequency of repeat PCI after TAVR was low in both no PCI vs. PCI (2.4 % vs. 1.2 %) at 1 year; PCI was associated with a lower rate of repeat PCI (HR: 0.49, 95 % CI: 0.30-0.80). Sensitivity analysis revealed an E-value of 3.5 for repeat PCI (E-value for lower CI for HR: 1.81). PCI was not linked to reductions in MI, heart failure exacerbation, all-cause hospitalization, major bleeding, or permanent pacemaker/implantable cardioverter defibrillator. CONCLUSION: This analysis showed that PCI prior to TAVR was not associated with improvement in all-cause mortality. However, PCI was associated with a reduced rate of repeat PCI at 1 year.

OBJECTIVE: To assess the absolute treatment effects of intravascular imaging guided versus angiography guided percutaneous coronary intervention in patients with coronary artery disease, considering their baseline risk. DESIGN: Systematic review and meta-analysis. DATA SOURCES: PubMed/Medline, Embase, and Cochrane Library databases up to 31 August 2023. STUDY SELECTION: Randomized controlled trials comparing intravascular imaging (intravascular ultrasonography or optical coherence tomography) guided versus coronary angiography guided percutaneous coronary intervention in adults with coronary artery disease. MAIN OUTCOME MEASURES: Random effect meta-analysis and GRADE (grading of recommendations, assessment, development, and evaluation) were used to assess certainty of evidence. Data included rate ratios and absolute risks per 1000 people for cardiac death, myocardial infarction, stent thrombosis, target vessel revascularization, and target lesion revascularization. Absolute risk differences were estimated using SYNTAX risk categories for baseline risks at five years, assuming constant rate ratios across different cardiovascular risk thresholds. RESULTS: In 20 randomized controlled trials (n=11 698), intravascular imaging guided percutaneous coronary intervention was associated with a reduced risk of cardiac death (rate ratio 0.53, 95% confidence interval 0.39 to 0.72), myocardial infarction (0.81, 0.68 to 0.97), stent thrombosis (0.44, 0.27 to 0.72), target vessel revascularization (0.74, 0.61 to 0.89), and target lesion revascularization (0.71, 0.59 to 0.86) but not all cause death (0.81, 0.64 to 1.02). Using SYNTAX risk categories, high certainty evidence showed that from low risk to high risk, intravascular imaging was likely associated with 23 to 64 fewer cardiac deaths, 15 to 19 fewer myocardial infarctions, 9 to 13 fewer stent thrombosis events, 28 to 38 fewer target vessel revascularization events, and 35 to 48 fewer target lesion revascularization events per 1000 people. CONCLUSIONS: Compared with coronary angiography guided percutaneous coronary intervention, intravascular imaging guided percutaneous coronary intervention was associated with significantly reduced cardiac death and cardiovascular outcomes in patients with coronary artery disease. The estimated absolute effects of intravascular imaging guided percutaneous coronary intervention showed a proportional relation with baseline risk, driven by the severity and complexity of coronary artery disease.

Background: Transcatheter aortic valve intervention (TAVI) can lead to the embolization of debris. Capturing the debris by cerebral embolic protection (CEP) devices may reduce the risk of stroke. New evidence has allowed us to examine the effects of CEP in patients undergoing TAVI. We aimed to assess the effects of CEP overall and stratified by the device used (SENTINEL or TriGuard) and the surgical risk of the patients. Methods: We selected randomized controlled trials using electronic databases through September 17, 2022. We estimated random-effects risk ratios (RR) with (95% confidence interval) and calculated absolute risk differences at 30 days across baseline surgical risks derived from the TAVI trials for any stroke (disabling and nondisabling) and all-cause mortality. Results: Among 6 trials (n = 3921), CEP vs. control did not reduce any stroke [RR: 0.95 (0.50-1.81)], disabling [RR: 0.75 (0.18-3.16)] or nondisabling [RR: 0.99 (0.65-1.49)] strokes, or all-cause mortality [RR: 1.23 (0.55-2.77)]. However, when analyzed by device, SENTINEL reduced disabling stroke [RR: 0.46 (0.22-0.95)], translating into 6 fewer per 1000 in high-risk, 3 fewer per 1000 in intermediate-risk, and 1 fewer per 1000 in low surgical-risk patients. CEP vs. control did not reduce the risk of any bleeding [RR: 1.03 (0.44-2.40)], major vascular complications [RR: 1.41 (0.57-3.48)], or acute kidney injury [RR: 1.36 (0.57-3.28)]. Conclusions: This updated meta-analysis showed that SENTINEL CEP might reduce disabling stroke in patients undergoing TAVI. Patients with high and intermediate surgical risks were most likely to derive benefits.
RESUMO
The association of repeat revascularization after percutaneous coronary intervention (PCI) with mortality is uncertain. To assess the association of repeat revascularization after PCI with mortality in patients with coronary artery disease (CAD). We identified randomized controlled trials comparing PCI with coronary artery bypass graft (CABG) or optimal medical therapy (OMT) using electronic databases through January 1, 2022. We performed a random-effects meta-regression between repeat revascularization rates after PCI (absolute risk difference [%] between PCI and CABG or OMT) with the relative risks (RR) of mortality. We assessed surrogacy of repeat revascularization for mortality using the coefficient of determination (R2), with threshold of 0.80. In 33 trials (21,735 patients), at median follow-up of 4 (2-7) years, repeat revascularization was higher after PCI than CABG [RR: 2.45 (95% confidence interval, 1.99-3.03)], but lower vs OMT [RR: 0.64 (0.46-0.88)]. Overall, meta-regression showed that repeat revascularization rates after PCI had no significant association with all-cause mortality [RR: 1.01 (0.99-1.02); R2=0.10) or cardiovascular mortality [RR: 1.01 (CI: 0.99-1.03); R2=0.09]. In PCI vs CABG (R2=0.0) or PCI vs OMT trials (R2=0.28), repeat revascularization did not meet the threshold for surrogacy for all-cause or cardiovascular mortality (R2=0.0). We observed concordant results for subgroup analyses (enrollment time, follow-up, sample size, risk of bias, stent types, and coronary artery disease), and multivariable analysis adjusted for demographics, comorbidities, risk of bias, MI, and follow-up duration. In summary, this meta-regression did not establish repeat revascularization after PCI as a surrogate for all-cause or cardiovascular mortality.

Tricuspid regurgitation (TR) is being increasingly recognized in patient population. We aimed to investigate the long-term mortality due to TR in the United States (US) and demographic disparities in TR-related mortality using "Multiple Cause of Death data" via the Centers for Disease Control and Prevention Wide-Ranging On-line Data for Epidemiologic Research datasets, 1999 to 2019. The results from present analysis suggest that TR related deaths in the US may have increased over the last 20 years. This trend may justify greater focus on timely diagnosis and management of TR.

Background: The effects of aspirin in adults without atherosclerotic cardiovascular disease (ASCVD), stratified by statin use across different ASCVD risks, remain uncertain. Objectives: The purpose of this study was to examine the effects of aspirin in adults without ASCVD, stratified by statin use across different ASCVD risks. Methods: We searched databases through March 2022 and selected randomized controlled trials of aspirin without ASCVD and follow-up of ≥1 year. We used random-effects models and estimated relative and absolute risks for cardiovascular outcomes, major bleeding, and mortality over 5 years. We calculated absolute risk differences assuming constant relative risks (RRs) across statin use and ASCVD risks. The Cholesterol Treatment Trialists Collaboration, and the ASCEND (A Study of Cardiovascular Events in Diabetes) trial were used to estimate baseline risks. Results: In 16 trials [171,215 individuals; median age, 64 (Q1-Q3: 60-65) years], aspirin vs control reduced myocardial infarction (MI) [RR: 0.85 (95% CI: 0.77-0.95)] but increased major bleeding [RR: 1.48 (95% CI: 1.32-1.66)]. Aspirin did not reduce mortality. Statin vs no statin was associated with lower bleeding and MI risk; the bleeding and MI risk were proportional to ASCVD risk. For every 10,000 adults, aspirin reduced MI (very low risk: 3 events as monotherapy or 1 event with statin; very high risk: 49 events as monotherapy or 37 events with statin) and increased major bleeding (very low risk: 21 events as monotherapy or 20 events with statin; very high risk: 98 events as monotherapy or 94 events with statin) proportional to baseline ASCVD risk. Conclusions: In adults without ASCVD, concomitant statin appeared to significantly reduce absolute risk reduction for MI associated with aspirin without influencing bleeding risk. The anticipated absolute risk of major bleeding with aspirin exceeds absolute MI benefits for every level of ASCVD risk.
RESUMO
Cardiac arrest (CA) among young adults (<45 y) with ischemic heart disease (IHD) remained understudied. We evaluated the trends in clinical profile, in-hospital mortality, and health care resource utilization in CA-related hospitalizations among young adults with IHD. National Inpatient Sample (2004-2018) was used to identify adults aged 18-45 years. Of 77,359 weighted CA-related hospitalizations (mean age: 39 [0.05] y; 34.3% women), 65% had a myocardial infarction (MI), and 58% had a shockable rhythm. Between 2004 and 2018, CA-related hospitalizations among young adults with IHD increased from 1.8% to 2.4%. Overall, in-hospital mortality was 36.4%, which was higher for women vs men (40.4% vs 34.2%; P < 0.001) and Black vs White adults (43.9% vs 33.3%; P < 0.001). In-hospital mortality increased from 33.5% to 38.1%, with a consistent upward trend in men, White adults, and both MI and non-MI cases. However, in STEMI (40%), in-hospital mortality decreased from 34.6% to 20.2% (p-trend <0.001), while it increased in NSTEMI (14.8%) from 34.3% to 47.5% (p-trend <0.001). Overall mean length of stay (LOS) (7-9 days) and mean inflation-adjusted care cost ($34,431-$44,646) increased over the study duration. CA-related hospitalizations and associated LOS and inflation-adjusted care costs have increased in the last 15 years. In-hospital mortality increased by â¼5% during the study period with a higher mortality in women and among black adults. While increased CA-related hospitalizations may reflect improved pre-hospital care, greater efforts are needed to address improve in-hospital survival in CA among young adults with IHD.

Pulmonary arterial hypertension is a common complication in patients with congenital heart disease (CHD), aggravating the natural course of the underlying defect. Pulmonary arterial hypertension (PAH) has a multifactorial etiology depending on the size and nature of the cardiac defect as well as environmental factors. Although progress has been made in disease-targeting therapy using pulmonary vasodilators to treat Eisenmenger syndrome, important gaps still exist in the evaluation and management of adult patients with CHD-associated PAH (PAH-CHD) who have systemic-to-pulmonary shunts. The choice of interventional, medical, or both types of therapy is an ongoing dilemma that requires further data. This review focuses on the evaluation and management of PAH-CHD in the contemporary era.
