ST-elevation myocardial infarction in nonagenarians: A nationwide analysis of trends and outcomes in the United States.

OBJECTIVE: To assess ST elevation myocardial infarction (STEMI) trends and outcomes in nonagenarians undergoing primary percutaneous coronary intervention (pPCI) compared to medical management. BACKGROUND: Although nonagenarians (age greater than 90 years) represent the fast-growing age decade of the US population, limited evidence is available regarding trends and outcomes of treatment strategies for STEMI in this population cohort. METHODS: We performed a retrospective analysis using the National Inpatient Sample (NIS) database to identify nonagenarians presenting with STEMI and treated with either pPCI or medical management. In-hospital mortality, in-hospital complications, length of stay and in-hospital costs were analyzed. RESULTS: Between 2010-2017, 41,042 STEMI hospitalizations were identified in nonagenarians, of which 11, 155 (27.2%) included pPCI whereas 29, 887 (72.8%) included medical management. STEMI hospitalizations among nonagenarians decreased over the study period. Overall unadjusted in-hospital mortality was 21.6%, and the hospitalizations that included pPCI had significantly lower mortality compared to the medical management (13.6% vs. 24.5%, p < .001). After adjusting for baseline characteristics, hospitalizations that included pPCI had 42.1% lower odds of in-hospital mortality (adjusted OR: 0.58, 95% CI: 0.50 to 0.67, p < .001). Altogether, in-hospital cardiac, bleeding and vascular complications, length of stay and in-hospital costs were higher in pPCI hospitalizations. CONCLUSION: In nonagenarians, STEMI mortality is high, but pPCI is associated with superior outcomes compared to medical management alone. Therefore, pPCI can be considered an acceptable treatment strategy in this population.

Sex differences in mortality and 90-day readmission rates after transcatheter aortic valve replacement: a nationwide analysis from the USA.

AIMS: To assess gender differences in in-hospital mortality and 90-day readmission rates among patients undergoing transcatheter aortic valve replacement (TAVR) in the USA. METHODS AND RESULTS: Hospitalizations for TAVR were retrospectively identified in the National readmissions database (NRD) from 2012 to 2017. Gender based differences in in-hospital mortality and 90-day readmissions were explored using multivariable logistic regression models. During the study period, an estimated 171 361 hospitalizations for TAVR were identified, including 79 722 (46.5%) procedures in women and 91 639 (53.5%) in men. Unadjusted in-hospital mortality and 90-day all-cause readmissions were significantly higher for women compared with men (2.7% vs. 2.3%, P = 0.002; 25.1% vs. 24.1%, P = 0.012, respectively). After adjusting for baseline characteristics, women had 13% greater adjusted odds of in-hospital mortality [adjusted odds ratio (aOR): 1.13, 95% confidence interval (CI): 1.02-1.26, P = 0.017], and 9% greater adjusted odds of 90-day readmission compared with men (aOR: 1.09, 95% CI: 1.05-1.14, P < 0.001). During the study period, there was a steady decrease in-hospital mortality (5.3% in 2012 to 1.6% in 2017; Ptrend < 0.001) and 90-day (29.9% in 2012 to 21.7% in 2017; Ptrend < 0.001) readmission rate in both genders. CONCLUSION: In-hospital mortality and readmission rates for TAVR hospitalizations have decreased over time across both genders. Despite these improvements, women undergoing TAVR continue to have a modestly higher in-hospital mortality, and 90-day readmission rates compared with men. Given the expanding indications and use of TAVR, further research is necessary to identify the reasons for this persistent gap and design appropriate interventions.

Effectiveness of Thrombolytic Therapy in Acute Embolic Stroke due to Infective Endocarditis.

Objective. To identify the role of thrombolytic therapy in acute embolic stroke due to infective endocarditis. Design. Case report. Setting. University hospital. Patient. A 70-year-old male presented with acute onset aphasia and hemiparesis due to infective endocarditis. His head computerized tomographic scan revealed left parietal sulcal effacement. He was given intravenous tissue plasminogen activator with significant resolution of the neurologic deficits without complications. Main Outcome Measures. Physical examination, National Institute of Health Stroke Scale, radiologic examination results. Conclusions. Thrombolytic therapy in selected cases of stroke due to infective endocarditis manifesting as major neurologic deficits can be considered as an option after careful consideration of risks and benefits. The basis for such favorable response rests in the presence of fibrin as a major constituent of the vegetation. The risk of precipitating hemorrhage with thrombolytic therapy especially with large infarcts and mycotic aneurysms should be weighed against the benefits of averting a major neurologic deficit.
