[Echocardiographic findings after SARS-CoV-2 infection in medical residents without previous cardiopulmonary pathology in a tertiary hospital].

Abstract

Background: SARS-CoV-2 disease is associated with a wide spectrum of cardiovascular, renal, and cognitive complications and effects. The most common cardiovascular findings are pericarditis, myocarditis and arrhythmias described in 5-11% of the general population. Specific information on cardiovascular outcomes in healthcare workers in Mexico is lacking.

Objective: To determine the echocardiographic findings after SARS-CoV-2 infection in residents at a tertiary care teaching hospital.

Material and methods: A prospective, cross-sectional, and selective study was performed. A sample of 62 resident physicians with a diagnosis of COVID-19 was selected from March 2020 to February 2023. Transthoracic echocardiograms were performed, and the findings were described.

Results: The main echocardiographic findings were: pericardial refractoriness (90.3%), pericardial effusion (6.5%), abnormal left ventricular mobility (1. 6%), abnormal diastolic function (8.1%), aortic regurgitation (6.5%), mitral regurgitation (19.4%), pulmonary regurgitation (35.5%), tricuspid regurgitation (80.6%), mean LVEF of 65% and PSAP of 23 mmHg.

Conclusions: The most relevant echocardiographic findings were refractory pericardium, pericardial effusion, left ventricular diastolic dysfunction, and valvular insufficiency, predominantly in men.
