Key result
Cardiac involvement on magnetic resonance imaging was detected in 49% of young, previously healthy patients who recovered from COVID-19, and was significantly associated with chest pain or dyspnea.
Why the study?
COVID-19 affects multiple organs including the heart, but the presence and prevalence of cardiac involvement in asymptomatic or symptomatic patients recovered from infection required evaluation.
What is the prevalence of cardiac involvement on CMR in young patients recovered from COVID-19 without prior chronic diseases?
Cross-Sectional (n=100)

What is the prevalence of cardiac involvement on CMR in young patients recovered from COVID-19 without prior chronic diseases?
Nearly half of young, previously healthy patients recovering from COVID-19 demonstrated cardiac involvement on CMR, which correlated with symptoms and mildly reduced biventricular function.
BACKGROUND: Coronavirus 2019 (COVID-19) causes morbidity and mortality in an increasing number of people worldwide. Although it mainly affects the respiratory system, it influences all organs, including the heart. It is associated with a broad spectrum of widespread cardiovascular problems ranging from mild myocardial injury to fulminant myocarditis. We aimed to evaluate the presence and prevalence of cardiac involvement in asymptomatic or symptomatic patients after they recovered from COVID 19 infection. METHODS: A total of 100 consecutive patients with COVID-19 proven by reverse transcription polymerase chain reaction (RT-PCR), under 40 years of age and without any known additional chronic diseases were analyzed retrospectively for cardiac magnetic resonance (CMR) results and symptoms. RESULTS: Cardiac involvement was detected in 49 out of 100 patients on CMR imaging. In the cardiac involvement group, the number of patients with chest pain and/or dyspnea was 41 (84%), which was statistically significant (p = 0.001). Twenty-four patients (47%) in the without cardiac involvement group were asymptomatic and this was also statistically significant (p = 0.001). LV ejection fraction was statistically significantly lower in the group with cardiac involvement (61% vs 66%, p = 0.001). LV stroke volume and tricuspid annular plane systolic excursion (TAPSE) were statistically significantly lower in patients with cardiac involvement (p = 0.028 and p = 0.019, respectively). CONCLUSION: Based on single center experience, myocardial involvement is common in symptomatic patients after COVID-19. More studies are needed for long-term side effects and clinical results in these patients.

Erdöl et al. (2021) conducted a cross-sectional in COVID-19 (n=100). COVID-19 recovery was evaluated on Cardiac involvement on CMR imaging. Cardiac involvement on magnetic resonance imaging was detected in 49% of young, previously healthy patients who recovered from COVID-19, and was significantly associated with chest pain or dyspnea.
