Troponin levels assessed between 72 h before and 48 h after the COVID-19 diagnosis were used to stratify the study population by the presence of acute and chronic myocardial injury, as defined by the Fourth Universal Definition of Myocardial Infarction. Among 4695 patients, those with chronic myocardial injury (n\u00a0=\u00a0319, 6.8%) had more comorbidities, including chronic kidney disease and heart failure, while acute myocardial injury (n\u00a0=\u00a01168, 24.9%) was more associated with increased levels of inflammatory markers. Both types of myocardial injury were strongly associated with impaired survival at 6 months [chronic: hazard ratio (HR) 4.17, 95% confidence interval (CI) 3.44\u20135.06; acute: HR 4.72, 95% CI 4.14\u20135.36], even after excluding events occurring in the first 30 days (chronic: HR 3.97, 95% CI 2.15\u20137.33; acute: HR 4.13, 95% CI 2.75\u20136.21). The mortality risk was not significantly different in patients with acute as compared with chronic myocardial injury (HR 1.13, 95% CI 0.94\u20131.36), except for a worse prognostic impact of acute myocardial injury in patients &amp;lt;65\u00a0years of age (P-interaction\u00a0=\u00a00.043) and in those without coronary artery disease (P-interaction\u00a0=\u00a00.041).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Chronic and acute myocardial injury represent two distinctive patterns of cardiac involvement among COVID-19 patients.
