Long-Term Effects of COVID-19

Abstract Background Cardiovascular complications; myocardial infarction (MI), ischemic stroke, and pulmonary embolism (PE), represent an important source of adverse outcomes in COVID-19 disease. Objectives To evaluate the incidence of thromboembolic events, specifically PE, MI and stroke; risk factors, management patterns and outcomes in patients who tested positive for COVID-19 through RT-PCR in a regional hospital. Methods We included 1125 adults patients admitted for COVID-19 infection between April 1 and October 30, 2020. The total cohort was analyzed by site of care: Intensive care (n=124) and nonintensive care (n=1001). Results Cardiovascular risk factors prevalence in patients with COVID-19 were: hypertension (25.5%), hyperlipidemia (23.2%) and diabetes (12%). Prophylactic anticoagulation and therapeutic anticoagulation was prescribed in intensive care group (91.1% and 33.1%, respectively) versus (84.8% and 12.5%, respectively) in nonintensive care setting. Frequencies of major arterial or venous thromboembolism, pulmonary embolism and myocardial infarction were highest in the intensive care group (29%, 20% and 8%, respectively) than nonintensive care cohort (1.4%, 0.7% and 0,5%, respectively). Hospital mortality was 29% in intensive care group and 1.3% in nonintensive care group. Conclusions Patients admitted for COVID-19 had a high risk of major arterial or venous thromboembolism events, especially in the intensive care setting, despite the use of thromboprophylaxis with heparin.
