Background Aortic stenosis–related mortality might vary across demographic subsets, regions, and states in the United States. Methods and Results We reviewed the death certificate data from the Centers for Disease Control and Prevention Wide‐Ranging OnLine Data for Epidemiologic Research database to examine aortic stenosis–related mortality trends from 2008 to 2018. Crude and age‐adjusted mortality rates (AAMRs) per 100 000 people and annual percentage change with 95% CIs were calculated. Between 2008 and 2018, AAMR reduced from 12.7 to 11.5 (average annual percentage change, −1.0 [95% CI, −1.5 to −0.5]), because of an accelerated decline between 2015 and 2018 (annual percentage change, −4.4 [95% CI, −6.0 to −2.7]). Older (aged >85 years), male, and White patients had higher death rates than younger, female, and non‐White patients, respectively. Although mortality reduction was similar across sexes, significant mortality reduction was limited to White patients only. The AAMRs were higher in rural than urban areas. States with AAMRs >90th percentile were distributed in the West and the Northeast, and <10th percentile in the South. The AAMRs for sex and race were highest in the West and lowest in the South. None of the states located in the Midwest showed a significant reduction in mortality. Mortality remained stable for hospital setting and nursing home/long‐term care facility, except that the number of deaths increased at home and hospice facility since 2014. Conclusions The reduction in mortality in patients with aortic stenosis was not consistent among demographic subsets and states. The substantial public health and economic implications call for determination of underlying clinical and socioeconomic factors to narrow the gap.

Abstract Background Inflammatory bowel disease (IBD) is associated with an increased acute coronary syndrome (ACS) risk. Data are limited regarding the epidemiology and outcomes of ACS in patients with IBD. Methods A retrospective cohort analysis of patients with IBD admitted for ACS in the U.S. Healthcare Cost and Utilization Project National Inpatient Sample for 2005 to 2015 was conducted. We analyzed trends in IBD-ACS admissions and mortality, differences in risk profiles, management strategies, and in-hospital mortality between IBD-ACS and non-IBD ACS and between ulcerative colitis (UC) and Crohn disease (CD). Results We studied 6,872,415 non-IBD ACS and 24,220 IBD-ACS hospitalizations (53% with CD). During the study period, the number of hospitalizations for IBD-ACS increased, particularly those related to CD. Compared with non-IBD ACS, patients with IBD-ACS had a lower prevalence of cardiovascular risk factors and similar rates of coronary angiography and revascularization. The in-hospital mortality rate was lower with IBD-ACS (3.9%) compared with non-IBD ACS (5.3%; odds ratio, 0.81; 95% confidence interval, 0.69-0.96; P = 0.011) and was stable between 2005 and 2015. Risk factors, ACS management strategies, and mortality were similar between CD and UC. Coagulopathy, weight loss, and gastrointestinal bleeding were more frequent in IBD-ACS and were strong independent predictors of mortality. Conclusions Hospitalizations for ACS in patients with IBD increased in recent years but death rates were stable. The ACS-related risk profiles and mortality were modestly favorable with IBD-ACS than with non-IBD ACS and were similar between CD and UC. Complications more frequently associated with IBD were strongly associated with mortality. These findings indicate that aggressive management of IBD and ACS comorbidities is required to improve outcomes.

Background The management of patients with severe but asymptomatic aortic stenosis is challenging. Evidence on early aortic valve replacement (AVR) versus symptom-driven intervention in these patients is unknown. Methods Electronic databases were searched, articles comparing early-AVR with conservative management for severe aortic stenosis were identified. Pooled adjusted odds ratio (OR) was computed using a random-effect model to determine all-cause and cardiovascular mortality. Results A total of eight studies consisting of 2201 patients were identified. Early-AVR was associated with lower all-cause mortality [OR 0.24, 95% confidence interval (CI) 0.13–0.45, P ≤ 0.00001] and cardiovascular mortality (OR 0.21, 95% CI 0.06–0.70, P = 0.01) compared with conservative management. The number needed to treat to prevent 1 all-cause and cardiovascular mortality was 4 and 9, respectively. The odds of all-cause mortality in a selected patient population undergoing surgical AVR (SAVR) (OR 0.16, 95% CI 0.09–0.29, P ≤ 0.00001) and SAVR or transcatheter AVR (TAVR) (OR 0.53, 95% CI 0.35–0.81, P = 0.003) were significantly lower compared with patients who are managed conservatively. A subgroup sensitivity analysis based on severe aortic stenosis (OR 0.24, 95% CI 0.11–0.52, P = 0.0004) versus very severe aortic stenosis (OR 0.20, 95% CI 0.08–0.51, P = 0.0008) also mirrored the findings of overall results. Conclusion Patients with asymptomatic aortic valve stenosis have lower odds of all-cause and cardiovascular mortality when managed with early-AVR compared with conservative management. However, because of significant heterogeneity in the classification of asymptomatic patients, large scale studies are required.
