Background: The association between Coronavirus Disease-2019 (COVID-19) and new-onset cardiomyopathy (NOC) is unclear. Objectives: We aim to assess the incidence of NOC in hospitalized COVID-19 patients and its impact on short- and long-term survival. Methods: We retrospectively studied 2219 COVID-19 patients hospitalized between March 2020 and February 2022 who underwent an in-hospital echocardiogram. NOC was defined as a left-ventricular ejection fraction (LVEF) reduction of >10%, resulting in an LVEF of <54% for females and <52% for males. The 30-day and 1-year survival outcomes in patients without and with NOC were studied. Results: Among 25,943 hospitalized COVID-19 patients, 2219 met our inclusion criteria, with 209 (9.4%) having NOC. NOC patients were more likely to be male (56.1% vs. 68.4%, p = 0.001) and have chronic kidney disease (51.4% vs. 60.3%, p = 0.018). They had a higher 30-day mortality rate (29.1% vs. 32%, p = 0.033), but the 1-year survival rate was similar between the patients without and with NOC (36.9% vs. 41.6%, p = 0.12). Multivariable regression revealed that advanced age, admission to intensive care unit, mechanical ventilation, treatment with glucocorticoids, and treatment with vasopressors were associated with higher odds of 30-day mortality in NOC patients. Only 74 (35.4%) NOC patients had follow-up echocardiograms after discharge, of which 47 showed persistent cardiomyopathy. Conclusions: NOC can affect around 1 out of 10 hospitalized COVID-19 patients undergoing echocardiography. While NOC was associated with worse short-term survival, it did not impact the long-term mortality of these patients. Persistent LVEF deficits in some patients emphasize the need for improved outpatient follow-up to identify at-risk individuals and optimize treatment.
