Background Although echocardiography is widely used to measure left ventricular ejection
fraction (LVEF), its prognostic value has not been demonstrated in a broad range of patients
including those acutely hospitalized for cardiac or noncardiac causes. We determined
whether greater degrees of left ventricular systolic dysfunction were associated with
progressively increasing risks of death or cardiovascular hospitalizations among patients in
hospital or outpatient settings. Methods A total of 27,323 patients with LVEF measured and …
