The COVID-19 has affected the populations worldwide. The case reports of hospitalized patients across the world suggest that COVID-19 affects the cardiovascular system, but the actual impact remains unclear. The objective of this study is to investigate the presence of myocardial injury in patients recovered from COVID-19.

This is a prospective observational cohort study that includes 100 patients recovered from COVID-19 during April-June 2020. The primary measures and outcomes of the study included cardiac blood markets, cardiovascular magnetic resonance (CMR) imaging, and demographic characteristics of the risk factor-matched participants. The results were then compared with healthy volunteers.

The researchers found that out of the 100 patients recently recovered from COVID-19, high-sensitivity troponin T was detectable in 71 of them at the time of CMR. When compared with healthy and risk factor-matched controls, recently recovered patients had lower left ventricular ejection fraction, high left ventricle mass, high left ventricle volumes, and raised native T1 and T2. 78 recovered patients had abnormal CMR findings, including increased myocardial T1 and T2, pericardial enhancement, and myocardial late gadolinium enhancement.

The research concluded that cardiac involvement in 78 and myocardial inflammation in 60  of the total recovered patients. These findings indicate the long-term cardiovascular consequences of COVID-19.
