Aim. To carry out comparative analysis of echocardiographic and electrocardiographic (ECG) data of survivors and deceased patients with COVID-19 (sub-analysis of the international register “Dynamics analysis of comorbidities in SARS-CoV-2 survivors”).Material and methods. The study presents the results of a sub-analysis of the international AKTIV registry, which was called AKTIV CARDIO. Data were collected from 9 medical centers in the Russian Federation. AKTIV CARDIO included 973 hospitalized patients, of which 50 patients died during hospitalization.Results. Comparative analysis of echocardiographic parameters revealed that 4 parameters differed in deceased patients compared to survivors: left ventricular ejection fraction (LVEF), right ventricular end diastolic dimension (RV EDD), right atrial (RA) short axis diameter and pulmonary artery systolic pressure (PASP). RA short axis diameter was higher in deceased patients compared with survivors (38,0 [36,0; 39,0] versus 35,0 [33,0; 38,0] mm, p=0,011). RV EDD was higher in deceased patients than in survivors (3,0 [29,0; 33,0] vs 28,0 [27,0; 32,0] mm, p=0,019). LVEF was lower in deceased patients compared with survivors (55 [52; 55] vs 60 [56; 65]%, p<0,001). PASP was higher in deceased patients compared with survivors (25 [21; 35] vs 20 [19; 25] mm Hg, p=0,006). Correlation analysis found that the largest number of correlations with markers of the infection severity was observed for RA short axis diameter and RV EDD. A comparative analysis of ECG data revealed that in deceased patients, compared with survivors, atrial fibrillation (AF) (21,4% vs 6,06%, p=0,001) and supraventricular premature beats (14,3% vs 3,36%, р=0,004) occurred more often. In addition, deceased patients had longer QTc interval (440 [416; 450] vs 400 [380; 430] ms, p<0,001).Conclusion. Comparative analysis of echocardiographic data showed that deceased patients have more pronounced right heart remodeling, higher PASP and lower LVEF. Patient survival was related to RV and RA sizes. Right heart enlargement was associated with markers of infection severity. Echocardiographic parameters characterizing the right heart side can probably be independent prognostic factors in the acute COVID-19 period.
