Convalescent Phenotyping of Cardiac Injury During Hospitalization for Acute COVID-19

COVID-19 is associated with acute myocardial injury in hospitalized patients, and those with abnormal troponin lev-els are at higher risk for death.1 Medical comorbidities such as advanced age, cardiovascular disease (CVD), hyperten-sion, and the severity of COVID-19 infection have been associated with elevated troponin in retrospective analyses.2,3 The primary aim of the study was to prospec-tively determine the association of cardiac injury measured by high-sensitivity troponin and the phenotype of cardiac injury, as determined in contrast-enhanced cardiac mag-netic resonance (CMR) imaging.
