Abstrakt: Coronavirus disease 2019 (COVID-19) has high infectivity and causes extensive morbidity and mortality. Cardiovascular disease is a risk factor for adverse outcomes in COVID-19, but baseline left ventricular ejection fraction (LVEF) in particular has not been evaluated thoroughly in this context. We analyzed patients in our state's largest health system who were diagnosed with COVID-19 between March 20 and May 15, 2020. Inclusion required an available echocardiogram within 1 year prior to diagnosis. The primary outcome was all-cause mortality. LVEF was analyzed both as a continuous variable and using a cutoff of 40%. Among 396 patients (67 ± 16 years, 191 [48%] male, 235 [59%] Black, 59 [15%] LVEF ≤40%), 289 (73%) required hospital admission, and 116 (29%) died during 85 ± 63 days of follow-up. Echocardiograms, performed a median of 57 (IQR 11-122) days prior to COVID-19 diagnosis, showed a similar distribution of LVEF between survivors and decedents (P = 0.84). Receiver operator characteristic analysis revealed no predictive ability of LVEF for mortality, and there was no difference in survival among those with LVEF ≤40% versus >40% (P = 0.49). Multivariable analysis did not change these relationships. Similarly, there was no difference in LVEF based on whether the patient required hospital admission (56 ± 13 vs 55 ± 13, P = 0.38), and patients with a depressed LVEF did not require admission more frequently than their preserved-LVEF peers (P = 0.87). A premorbid history of dyspnea consistent with symptomatic heart failure was not associated with mortality (P = 0.74). Among patients diagnosed with COVID-19, pre-COVID-19 LVEF was not a risk factor for death or hospitalization.
