Patients recovering from moderate-to-severe COVID-19 pneumonia frequently exhibit subclinical myocardial dysfunction, including reduced global longitudinal strain and diastolic dysfunction, detectable by speckle-tracking echocardiography.
During the coronavirus pandemic (COVID-19), views have evolved in various fields of medicine due to a significant number of studies in the field of epidemiology of the new infection and its numerous complications, observation of patients in the post-COVID period, the formation of registries and the analysis of big data. As a result of the study, the main structural and functional changes of the heart were determined in patients with a history of pneumonia associated with COVID-19 infection according to standard echocardiography with the additional use of tissue myocardial Doppler imaging and 2D Speckle Tracking technology. The data obtained show that standard echocardiography, combined with an assessment of longitudinal deformation based on speckle-tracking echocardiography, is important and provides additional opportunities in the diagnosis of cardiovascular pathology in patients with COVID-19 infection.

Rodzina et al. (2024) conducted an observational in COVID-19 (n=66). COVID-19 pneumonia was evaluated on Reduced global longitudinal strain (GLS) by 2D speckle-tracking echocardiography (95% CI 72.0-91.0). In patients recovering from moderate to severe COVID-19 pneumonia, reduced global longitudinal strain was observed in 81% of cases and left ventricular diastolic dysfunction in 73%.
