Cardiovascular Involvement in Patients Recovered from COVID-19: Reality or Fantasy?

pp. 274-279

Abstract

Background: COVID-19 infection has been associated with cardiovascular complications in 7-28% of hospitalized patients, with the diagnosis based on biomarkers elevation. Subclinical cardiac involvement in outpatients recovered from COVID-19 represents a
growing concern, as well as mid- or long-term cardiovascular effects.
Objective: The aim of the present study was to determine the usefulness of detecting cardiovascular involvement in outpatients recovered from COVID-19, and its association with symptoms and risk factors.
Methods: Between September 2020 and March 2021, 668 patients >18 years were prospectively included. All the patients had to have COVID-19 confirmed diagnosis by a positive reverse transcription-polymerase chain reaction (RT-PCR) test in a respiratory
tract sample COVID-19. They were evaluated with physical examination, electrocardiogram (ECG) and Doppler echocardiography. Patients with symptoms suggestive of risk or abnormal findings on ECG or echocardiogram underwent cardiac magnetic resonance imaging (CMRI) with gadolinium-based contrast agent.
Results: Mean age was 42.9 ± 14.9 years and 56.9% were women; 12.9% were hypertensive, 4.3% were diabetic and 6.9% obese. Overall, 57.6% had no cardiovascular risk factors and only 4.2% had a history of cardiovascular disease. The disease was mild in 73.2%; 16.3% required hospitalization and 1.05% needed mechanical ventilation. Only 5 patients had myocarditis diagnosed by CMRI, and both pericardial effusion and abnormal repolarization were significantly associated with myocarditis (p < 0.0001).
Conclusions: Abnormal ECG or echocardiographic findings were uncommon in our cohort. The diagnosis of viral myocarditis was made in 5 cases with clinical signs and symptoms, and was confirmed by CMRI.
