STRATS-AHF (STrain for Risk Assessment and Therapeutic Strategies in patients with Acute Heart Failure) registry enrolled 4,312 patients hospitalized for acute HF from 3 tertiary university hospitals (Seoul National University Bundang Hospital, Seoul National University Hospital, and Chungnam National University Hospital) from January 2009 through December 2016.
Patients with signs or symptoms of heart failure and either lung congestion, or objective findings of left ventricular (LV) systolic dysfunction or structural heart disease, were eligible for the study. Echocardiography was performed and both LV ejection fraction (LVEF) and LV global longitudinal strain (LV-GLS), right ventricular GLS (RV-GLS) were measured.
