Abstract
PURPOSE
The study of quality of life (QOL) in patients with CHF with preserved LVEF (left ventricular ejection fraction) and a symptom of bendopnea with different levels of salt intake. Materials and methods. The study included 66 patients. The main symptoms of CHF were edema in 54.5% of cases, dyspnea in 77% of cases, ascites was detected in only 2 patients, an enlarged liver in 7 patients. Abdominal obesity was detected in 53 patients. Quality of life was assessed by the SF‑36 questionnaire, the level of salt intake was assessed by the Charlton: SaltScreener questionnaire. Results. On average, the time of occurrence of the bendopnea was 22.5±9.3 seconds, the minimum was 5 seconds. The absence of the effect of abdominal obesity on the risk of bendopnea (relative risk 1.18 [0.76; 1.83]) was revealed. According to the SF‑36 questionnaire, a decrease in physical health indicators (median 31.3 points [20.7; 42.3]) and psychological health (average score 43.2±21.7) was found. In patients with bendopnea, QOL was reduced due to both physical and mental health, unlike patients without bendopnea: physical functioning (Physical Functioning - PF) 24.8±16.1 against 47±28.9 points, p=0.001 ; role‑based functioning due to physical condition (Role‑Physical Functioning - RP), 0 [0; 25] vs. 37.5 [0; 100] points, p=0.008; general health (General Health - GH) 29.9±15.8 against 50±14.2 points, p=0.0005, social functioning (Social Functioning - SF) 56 ± 38 against 78.9 ± 17.8 points ; p = 0.004. Multidimensional regression analysis revealed the relationship between the time of occurrence of the symptom bendopnea and the level of salt intake, physical and psychological activity (r2=0.25; p<0.009). The time of onset of the symptom of bendopnea in patients with CHF decompensation was significantly longer (18.9±8.7 vs. 26.2±8.5 seconds, p=0.003). The presence of diseases such as hypertension, COPD, IHD, atrial fibrillation, cerebrovascular disease did not significantly affect QOL (p> 0.05), while the presence of bronchial asthma or chronic kidney disease significantly reduced QOL of patients (p<0.05). Conclusion. The presence of the symptom bendopnea significantly reduces the quality of life of patients with CHF with preserved LVEF (left ventricular ejection fraction).
