Abstract

Background: Cardiac injury has been linked to a poor prognosis during COVID-19 disease. Nevertheless, the risk factors associated are yet to be thoroughly investigated. Objectives: We sought to compare demographical characteristics and in-hospital outcomes in patients infected by the SARS-CoV-2 with and without cardiac injury, to further investigate the prevalence of acute cardiac injury as well as its impact on their outcomes in COVID-19-patients. Methods: We included in a retrospective analysis, all COVID-19 patients admitted between October first and December first, 2020, at the University Hospital Center of Oujda (Morocco) who underwent a troponin assay which was systematically measured on admission. The study population was divided into two groups: cardiac-injured patients and those without cardiac injury. Clinical, biological data and in-hospital outcomes were compared between the two groups. Results: 298 confirmed COVID-19 cases were included. Our study found that compared to non-cardiac-injured, cardiac-injured patients are older, with higher possibilities of existing comorbidities including hypertension (68 [42.2%] vs 40 [29.2%], P = 0.02), diabetes (81 [50.3%] vs 53 [38.7%] P = 0.044), the need for mechanical ventilation, ICU admission and mortality. A Cox proportional hazards regression analysis shows a significantly increased risk of death among cardiac-injured COVID-19-patients as compared to non-cardiac injured. (HR, 1.620 [CI 95%: 2.562-1.024]) Conclusion: Our retrospective cohort found that old age, comorbidities, a previous history of CAD, were significantly associated with acute cardiac injury. COVID-19 patients with acute cardiac injury are at a higher risk of ICU admission, and death.
