Comparison of cardiovascular and psychological profile of young military men after COVID-19 with and without pneumonia

Abstract

Aim. To compare the cardiovascular and psychological profile of young military population after coronavirus disease 2019 (COVID-19) with/without pneumonia. Material and methods. We examined 26 military men under 30 years of age (22,3±3,7 years/21,0 [19,8; 24,3] years) with documented COVID 19 (3 months±2 weeks after two virus-negative polymerase chain reaction tests). The participants were divided into 2 groups: experimental group (n=16) — those with COVID-19 pneumonia; comparison group (n=10) — those without pneumonia. All subjects underwent a complex of clinical and diagnostic tests. Results. Military men with COVID-19 pneumonia were significantly older (23,0 [20,5; 28,5] years vs 19,5 [19,0; 20,0] years, p=0,001). They had a prolonged PQ interval (154,5 [140,0; 163,5] ms vs 137,0 [134,0; 144,0] ms; p=0,014). According to echocardiography, the following parameters were significantly larger in experimental group: anteroposterior right ventricular dimension (26,0 [24,5; 27,5] mm vs 23,5 [22,0; 25,0] mm, p=0,012), right atrium length (48,0 [46,0; 51,5] mm and 45,5 [44,0; 47,0] mm, p=0,047), tricuspid regurgitation peak gradient (18,0 [15,5; 22,0] mm vs 14,0 [12,0; 20,0] mm, p=0,047), pulmonary artery systolic pressure (PASP) (30,3 [27,6; 34,0] mm Hg vs 23,0 [20,5; 30,5] mm Hg, p=0,038), mean pulmonary artery pressure (20,3 [18,9; 22,7] mm Hg vs 16,8 [14,5; 20,6] mm Hg, p=0,038). The estimated pulmonary vascular resistance was significantly higher in the study group (1,50 [1,2; 1,8] Wood units vs 1,17 [1,1; 1,2] Wood units,
