Questions LVEF-based prognosis in heart failure; leaves open whether preserved EF warrants distinct management in prospective studies.
Cohort (n=1,252)
Alfonso Varela‐Román (2005) conducted a cohort in Congestive heart failure (n=1,252). Preserved left ventricular systolic function (LVEF ≥ 50%) vs. Deteriorated left ventricular systolic function (LVEF < 50%) was evaluated on Survival. Preserved left ventricular systolic function (LVEF ≥50%) was associated with similar survival compared to deteriorated systolic function (LVEF <50%) in patients with congestive heart failure.
