RESUMO
BACKGROUND: Based on worldwide registries, approximately 50% of patients who underwent aortic valve replacement (AVR) via surgical aortic valve replacement are females. Although AVR procedures have improved greatly in recent years, differences in outcome including mortality between sexes remain. We aimed to investigate the trends in SAVR outcomes in females versus males. METHODS: Using the 2011-2017 National Inpatient Sample (NIS) database, we identified hospitalizations for patients with diagnosis of aortic stenosis during which SAVR was performed. Patients' sociodemographic and clinical characteristics, procedure complications, and mortality were analyzed. Piecewise regression analyses were performed to assess temporal trends in SAVR utilization in females versus males. Multivariable analyses were performed to identify predictors of in-hospital mortality. RESULTS: A total of 392,087 hospitalizations for SAVR across the USA were analyzed. Utilization of SAVR in both sex patients decreased significantly during the years 2011-2017. Males compared to females had significantly higher rates of hyperlipidemia, chronic renal disease, peripheral artery disease, coronary artery disease and tended to be smokers. Differences in mortality rates among sexes were observed for SAVR procedures. Women had higher in-hospital mortality with 3.7% compared to men with 2.5% (OR 1.38 [95% CI 1.33-1.43, P<0.001]). In a multivariable regression model analysis adjusted for potential confounders, women had higher mortality risk with odd ratio (OR 1.38 [95% CI 1.33-1.43], P<0.001). Women had significantly higher rates of vascular complications (5.1% compared to men with 4.6%, P=0.002). CONCLUSIONS: Utilization of SAVR showed a downward trend during the study period. Higher in-hospital mortality was recorded in females compared to males.

BACKGROUND: Acute coronary syndrome (ACS) at a young age is uncommon. Limited data regarding the long-term follow-up and prognosis in this population are available. Our objectives were to evaluate the long-term clinical outcomes of patients presenting with ACS at a young age and to assess factors that predict long-term prognosis. METHODS: A retrospective analysis of consecutive young patients (male below 40 and female below 50 years old) that were admitted with ACS and underwent percutaneous coronary intervention (PCI) between the years 1997 and 2009. Demographics, clinical characteristics, and clinical outcomes including major cardiovascular (CV) events and mortality were analyzed. Multivariable cox proportional hazard model was performed to identify predictors of long-term prognosis. RESULTS: One-hundred sixty-five patients were included with a mean follow-up of 9.1±4.6 years. Most patients were men (88%), and mean age (years) was 36.8±4.2. During follow-up, 15 (9.1%) died, 98 (59.4%) patients had at least one major CV event, 22 (13.3%) patients had more than two CV events, and the mean number of recurrent CV events was 1.4±1.48 events per patient. In multivariate analysis, the strongest predictors of major CV events and/or mortality were coronary intervention without stent insertion (HR1.77; 95% CI 1.09-2.9), LAD artery involvement (HR 1.59; 95% CI 1.04-2.44) and hypertension (HR 1.6; 95% CI 1.0-2.6). CONCLUSION: Patients with ACS in young age are at high risk for major CV and/or mortality in long-term follow-up with a high rate of recurrent CV events. Close follow-up and risk factor management for secondary prevention have a major role, particularly in this population.
