Objective: To investigate the relationship between left ventricular diastolic function (LVDF) and autonomic nervous function in elderly patients with mild-to-moderate essential hypertension.Design: A total of 146 elderly patients with mild-to-moderate essential hypertension were enrolled in our hospital from January, 2015 to October, 2017. Blood pressure was recorded, and biochemical indexes and the N-terminal pro-brain natriuretic preptide (NT-proBNP) were investigated. 2-dimensional echocadiolography was used to measure the parameters of LVDF. Based on the classification standard of LVDF, all subjects were divided into two groups: normal LVDF group (n = 72), left ventricular diastolic dysfunction group (n = 74). At the same time, the dynamic electrocardiogram were investigated for all subjects to monitor the indexes of time on heart rate variability (HRV).Results: (1) The level of NT-proBNP, left ventricular mass index (LVMI), interventricular septal thickness (IVST) and LVPWT increased significantly (p < .05 for all), while the level of PNN50, rMSSD, SDANN and SDNN decreased significantly (p < .05 for all) in left ventricular diastolic dysfunction group (abnormal LVDF group) compared with that in normal LVDF group (normal LVDF group); (2) The partial correlation analysis showed that rMSSD, PNN50 and triangle index were negatively correlated with peak A (r = -0.208, -0.219, -0.211, p < .05 for all), and positive correlated with the ratio of peak E to peak A (E/A) (r = 0.179, 0.184, 0.181, p < .05); SDNN were negatively correlated with NT-proBNP and E/E’ (r = -0.183, -0.181, p < .05 for all), positive correlated with E’ (r = 0.178, p < .05); (3) Multiple stepwise regression analysis showed that peak A and E/A were independent influencing factors for PNN50 (β = -0.261, p = .004; β = 0.179, p = .016); E/E’ and NT-proBNP were independent influencing factor for SDNN (β = -0.163, p = .018; β = -0.172, p = .022).Conclusions: Left ventricular diastolic dysfunction is closely related to impaired autonomic nervous function in elderly patients with mild-to-moderate essential hypertension.

Цель работы - оценка связи дефицита витамина D в сыворотке крови и риска диастолической дисфункции у пожилых пациентов с артериальной гипертензией (АГ). В исследование включены 162 больных пожилого возраста (средний возраст - 65,4±5,2 года) с АГ: 1-ю группу составили 67 пациентов с АГ без дефицита витамина D; 2-ю - 95 пациентов с АГ при наличии дефицита. Выявлено, что при дефиците витамина D в сыворотке крови больные были достоверно старше (Δ7,3 %, р<0,05), имели более высокий ИМТ (Δ9,6 %, р<0,05), меньшую дистанцию при тесте шестиминутной ходьбы (Δ10,4 %, р<0,05), чаще (72,6 %) имели диастолическую дисфункцию ЛЖ (ДД ЛЖ). Больные АГ с ДД ЛЖ при дефиците витамина D в сыворотке имели худший метаболический профиль - у них установлены более высокие значения общего холестерина (Δ15,7 %, р<0,05), триглицеридов (Δ15,2 %, р<0,05), индекса НОМА-IR (Δ12 %, р<0,05) и более низкие значения ЛПВП (Δ11,9 %, р<0,05). У больных АГ с ДД ЛЖ при дефиците витамина D качество жизни ниже, чем у больных с адекватным его уровнем. Больные пожилого возраста с АГ имели незначительную разницу по частоте встречаемости ДД ЛЖ между изучаемыми группами с разным статусом витамина D. Тем не менее, пожилые больные АГ при дефиците витамина D в сыворотке имели более выраженные нарушения диастолической дисфункции ЛЖ, липидного и углеводного обмена. Качество жизни по опроснику SF-36 у пожилых больных АГ при дефиците витамина D в сыворотке крови было достоверно ниже, чем в группе с адекватным его содержанием. The aim of the study was to evaluate the relationship between serum vitamin D deficiency and the risk of diastolic dysfunction in elderly patients with arterial hypertension. The study included 162 elderly patients (mean age 65,4±5,2 years) with arterial hypertension. The first group consisted of 67 patients with hypertension without vitamin D deficiency, the second-95 patients with hypertension with deficiency. It was revealed that the patients with vitamin D deficiency in the blood serum were significantly older (Δ7,3 %, p<0,05), had a higher body mass index (Δ9,6 %, p<0,05), a shorter distance in the 6-minute walk test (Δ10,4 %, p<0,05), and more often (72,6 %) had left ventricular diastolic dysfunction (LV DD). Patients with hypertension with LV DD in the presence of vitamin D deficiency in serum had a worse metabolic profile - they had higher values of total cholesterol (Δ15,7 %, p<0,05), triglycerides (Δ15,2 %, p<0,05), the НOMA-IR index (Δ12 %, p<0,05) and lower HDL values (Δ11,9 %, p<0,05). In patients with hypertension with LV DD in the presence of vitamin D deficiency, the quality of life is lower than in patients with adequate levels of it. Conclusions. Elderly patients with hypertension had a slight difference in the incidence of LV DD between the study groups with different vitamin D status. However, elderly patients with hypertension with serum vitamin D deficiency had more pronounced disorders of LV diastolic dysfunction, lipid and carbohydrate metabolism. The quality of life according to the SF-36 questionnaire in elderly patients with hypertension with vitamin D deficiency in the blood serum was significantly lower than in the group with adequate vitamin D content.
