Abstract

Myocardial injury, which is present in >20% of patients hospitalized for COVID-19, is associated with increased short-term mortality, but little is known about its mid- and long-term consequences. We evaluated the association between myocardial injury with one-year mortality and readmission in 172 COVID-19 patients discharged alive. Patients were grouped according to the presence or absence of myocardial injury (defined by hs-cTn levels) on admission and matched by age and sex. We report mortality and hospital readmission at one year after admission in all patients and echocardiographic, laboratory and clinical data at six months in a subset of 86 patients. Patients with myocardial injury had a higher prevalence of hypertension (73.3% vs. 50.0%, p = 0.003), chronic kidney disease (10.5% vs. 2.35%, p = 0.06) and chronic heart failure (9.3% vs. 1.16%, p = 0.03) on admission. They also had higher mortality or hospital readmissions at one year (11.6% vs. 1.16%, p = 0.01). Additionally, echocardiograms showed thicker walls in these patients (10 mm vs. 8 mm, p = 0.002) but without functional disorder. Myocardial injury in COVID-19 survivors is associated with poor clinical prognosis at one year, independent of age and sex, but not with echocardiographic functional abnormalities at six months.
