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).
Aim To evaluate the risk of major cardiovascular complications (CVC) in patients with chronic heart failure (CHF) with intermediate and preserved ejection fraction (EF) depending on the presence of bendopnea symptom.Material and methods The study included 104 patients with stage II CHF and left ventricular EF ≥40 %. Mean age of the patients was 72.8±10.6 years. A test for detection of bendopnea symptom was performed for all patients. Two groups were formed: group 1, 69 patients with the bendopnea symptom and group 2, 35 patients with a negative test. Follow-up duration was 24 months. The composite endpoint (CEP) was death and hospitalization for any CVC.Results Mean time to the bendopnea symptom was 17.3±6.61 s. At two years of follow-up, the CEP was observed in 36 (34.6 %) patients, including 30 (43.5 %) patients in group 1 and 6 (17.1 %) patients in group 2. 12 patients died, and 9 of them had the bendopnea symptom. 21 patients of group 1 were hospitalized for CVC. Risk of CEP was significantly 1.7 times higher for men (relative risk, RR 1.7 [1.1; 2.6]) than for women. The presence of bendopnea symptom increased the risk of CEP 1.4 times (ОР 1.4 [1.1;1.9]) for women and 2.3 times (RR 2.3 [1.4; 3.6]) for men.Conclusion Results of the study demonstrated an unfavorable effect of bendopnea symptom on risk of CEP during the two-year follow-up of CHF patients with preserved and intermediate EF.
Purpose. Analysis of the incidence of COVID-19 in patients from the register «Management of chronic patients with multiple diseases» with a previously established CHF diagnosis, depending on the presence or absence of a symptom of bendopnea. Materials and methods. Retrospective analysis of electronic outpatient records of 121 patients with CHF with and without bendopnea symptom, with an assessment of the incidence of COVID-19. For statistical processing of the data obtained, we used the R language and the RStudio software environment. Results. The average age of the patients was 74.38±9.83 years. Bendopnea symptom occurred in 60,3% (n = 73) of the studied patients. The incidence of COVID-19 was 14% (n = 17), of which 88% were patients with the symptom of bendopnea (p-value = 0.023, Х2 = 5.17). The chance of COVID-19 in patients with bendopnea was higher than in patients without symptom of bendopnea (OR 5.8 (1.2; 26.7), p = 0.013). Conclusion. The presence of a symptom of bendopnea in patients with CHF increases the risk of COVID-19. A statistically significant relationship was established between the presence of a symptom of bendopnea, the level of left ventricular ejection fraction and the incidence of COVID-19.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
