Study outcomes were all-cause death, cardiovascular and non-cardiovascular death, sudden cardiac death (SCD)\/SCD equivalent events, heart failure (HF) events, and the composite cardiovascular outcome including cardiovascular death, SCD\/SCD equivalent events, admission for HF, and heart transplantation.<\/jats:p><\/jats:sec><jats:sec id=\"sec003\"><jats:title>Results<\/jats:title><jats:p>Women were 5 years older (women 59.9\u00b113.5 vs. men 54.9\u00b111.4 years), had worse dyspnea, and greater left ventricular (LV) diastolic dysfunction and obstructive physiology at presentation. Women compared to men had higher all-cause mortality and cardiovascular event rates, driven by more cardiovascular deaths and heart failure (HF) events. Conversely, non-cardiovascular mortality was not different between the sexes. Female sex was independently associated with all-cause death (HR 1.88, 95% CI 1.11\u20133.20) and composite cardiovascular events (HR 3.60, 95% CI 2.00\u20136.49), independent of age, body mass index, New York Heart Association class, SCD risk score, and LV ejection fraction. When stratified by the age of 60, sex differences were not significant at &lt;60 years; however, at \u226560 years, women had worse LV diastolic function, greater obstructive physiology, as well as worse survival and composite cardiovascular outcomes.
