Systolic aortic regurgitation predicts all-cause mortality and hospitalization in outpatients with heart failure and preserved ejection fraction

摘要

Systolic aortic regurgitation (SAR) is considered to be a specific sign of heart failure (HF). However, the prevalence and importance of SAR in patients with HF and preserved ejection fraction (HFpEF) are unknown. Therefore, we sought to examine the prevalence of SAR in HFpEF outpatients and its association with all-cause mortality and/or cardiovascular hospitalizations during a 1-year follow-up.
