In summary, our prospective study showed normal LV function by LVEF in all patients 3 months after hospitalization for COVID-19. However, LV GLS, was reduced in 15% of the patients. Furthermore, we could not find any relationships between reduced GLS and disease severity (treatment at intensive care unit) or elevated high-sensitivity cardiac troponin after 3 months. The majority of the patients with reduced GLS had arterial hypertension prior to COVID-19 infection; this might explain the impaired LV function, but we cannot exclude that this was caused by COVID-19. Cardiac function might potentially be influenced by the antiviral medications, but we could not find such effect. Our study was, however, not originally designed for this purpose.
The number of patients is small and increases the risk of both type I and type II statistical errors. Another limitation is lack of comparison with echocardiographic examination during hospitalization. Our study underscores the need for more studies on long-term cardiovascular consequences after COVID-19.
