Cardiovascular Complications of COVID-19 Disease: A Narrative Review.

backgroundThe coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has had a profound impact on global health, extending beyond pulmonary complications. Cardiovascular involvement in COVID-19 is multifactorial and may be influenced by viral load, inflammatory response, and pre-existing comorbidities. DISCUSSION: Acute complications include myocardial injury, arrhythmias, acute coronary syndromes (ACS), heart failure, Takotsubo cardiomyopathy, myopericarditis, and cardiac arrest. Notably, atrial fibrillation (AF) emerges as a frequent arrhythmic complication, particularly among critically ill patients, and is associated with increased mortality. COVID-19-patients with concomitant ACS present more severe clinical profiles and higher rates of thrombotic events, including stent thrombosis. Cardiac arrest predominantly presents with non-shockable rhythms and is associated with dismal outcomes. COVID-19 also exacerbates heart failure, both by aggravating existing cardiac dysfunction or by precipitating de novo heart failure. Takotsubo cardiomyopathy and myocarditis, although less frequent, have been reported and are often underdiagnosed due to subtle clinical presentations. Right ventricular dysfunction, linked to pulmonary involvement, has emerged as a key prognostic marker. Post-COVID-19 syndrome include persistent cardiac abnormalities such as reduced ventricular function and myocardial inflammation. Cardiac magnetic resonance imaging and strain echocardiography have proven useful in identifying subclinical cardiac involvement.

conclusionsEarly recognition and monitoring of cardiovascular complications are crucial for improving outcomes in patients affected by COVID-19. This review summarizes current evidence regarding cardiovascular manifestations associated with COVID-19.
