The study of quality of life (QOL) in patients with CHF with preserved LVEF (left ventricular ejection fraction) and a symptom of bendopnea with di\ufb00erent levels of salt intake.\u00a0\n                    <jats:underline>Materials and methods.\u00a0<\/jats:underline>\n                    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\u201136 questionnaire, the level of salt intake was assessed by the Charlton: SaltScreener questionnaire.\u00a0\n                    <jats:underline>Results.\u00a0<\/jats:underline>\n                    On average, the time of occurrence of the bendopnea was 22.5\u00b19.3 seconds, the minimum was 5 seconds. The absence of the e\ufb00ect of abdominal obesity on the risk of bendopnea (relative risk 1.18 [0.76; 1.83]) was revealed. According to the SF\u201136 questionnaire, a decrease in physical health indicators (median 31.3 points [20.7; 42.3]) and psychological health (average score 43.2\u00b121.7) was found. In patients with bendopnea, QOL was reduced due to both physical and mental health, unlike patients without bendopnea: physical functioning (Physical Functioning \u2013 PF) 24.8\u00b116.1 against 47\u00b128.9 points, p=0.001 ; role\u2011based functioning due to physical condition (Role\u2011Physical Functioning \u2013 RP), 0 [0; 25] vs. 37.5 [0; 100] points, p=0.008; general health (General Health \u2013 GH) 29.9\u00b115.8 against 50\u00b114.2 points, p=0.0005, social functioning (Social Functioning \u2013 SF) 56 \u00b1 38 against 78.9 \u00b1 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&lt;0.009). The time of onset of the symptom of bendopnea in patients with CHF decompensation was significantly longer (18.9\u00b18.7 vs. 26.2\u00b18.5 seconds, p=0.003). The presence of diseases such as hypertension, COPD, IHD, atrial fibrillation, cerebrovascular disease did not significantly a\ufb00ect QOL (p&gt; 0.05), while the presence of bronchial asthma or chronic kidney disease significantly reduced QOL of patients (p&lt;0.05).\u00a0\n                    <jats:underline>Conclusion.\u00a0<\/jats:underline>\n                    The presence of the symptom bendopnea significantly reduces the quality of life of patients with CHF with preserved LVEF (left ventricular ejection fraction).\n                  <\/jats:p>","DOI":"10.18087\/cardio.2507","type":"journal-article","created":{"date-parts":[[2019,7,25]],"date-time":"2019-07-25T03:29:43Z","timestamp":1564025383000},"page":"24-32","source":"Crossref","is-referenced-by-count":1,"title":["Quality of life in patients with heart failure with preserved ejection fraction and the bendopnea symptom"],"prefix":"10.68900","volume":"59","author":[{"given":"D.
