Thirty-five sedentary individuals (67 ± 5 years) under treatment for hypertension were randomly assigned to water-based [n = 20; 30 min of seated resting in a heated swimming pool (30-32 ºC)] or land-based group [n = 15; 30 min of seated resting in a quiet room with controlled temperature (21-23 ºC)]. BP, heart rate, arterial stiffness and endothelial reactivity were measured before, immediately after (post) and 45 min after (recovery) each session. Heart rate reduced (P  less then  0.05) during the land-based session, and the reduction was maintained at post (~7 bpm) and recovery (~9 bpm), but no heart rate changes occurred during and after the water-based session. Systolic/diastolic BP increased (P =  less then 0.001) at post (~29/10 mmHg) and recovery (~10/7 mmHg) in the water-based group, but not in the land-based group. read more No significant changes in pulse wave velocity and endothelial reactivity occurred in both groups. These results suggest that the hemodynamic response to heated water immersion should be taken into account when assessing the effect of heated water-based exercise on postexercise hypotension in older individuals with hypertension.

The aim of this study was to evaluate the performance of using a deep learning-based method for measuring SBPs and DBPs and the effects of cuff inflation and deflation rates on the deep learning-based blood pressure (BP) measurement (in comparison with the manual auscultatory method).

Forty healthy subjects were recruited. SBP and DBP were measured under four conditions (i.e. standard deflation, fast deflation, slow inflation and fast inflation) using both our newly developed deep learning-based method and the reference manual auscultatory method. The BPs measured under each condition were compared between the two methods. The performance of using the deep learning-based method to measure BP changes was also evaluated.

There were no significant BP differences between the two methods (P > 0.05), except for the DBPs measured during the slow and fast inflation conditions. By applying the deep learning-based method, SBPs measured from fast deflation, slow inflation and fast inflation decreased significantly by 3.0, 3.5 and 4.7 mmHg (all P < 0.05), respectively, in comparison with the standard deflation condition. Whereas, corresponding DBPs measured from the slow and fast inflation conditions increased significantly by 5.0 and 6.8 mmHg, respectively (both P < 0.05). There were no significant differences in BP changes measured by the two methods in most cases (all P > 0.05, except for DBP change in the slow and fast inflation conditions).

This study demonstrated that the deep learning-based method can achieve accurate BP measurement under the deflation and inflation conditions with different rates.

Vitamin D has beneficial effects on vascular endothelial function, blood pressure (BP) and arterial stiffness. Arterial stiffness increases in early-stage hypertensive patients and it is a strong predictor of cardiovascular morbidity and mortality. The purpose of this study was to assess the association between serum 25-hydroxyvitamin D (25-OH D) levels and arterial stiffness in patients with newly diagnosed hypertension.

Our study included 100 newly diagnosed hypertensive patients (63 male, 37 female and mean age 51.7 ± 10.3 years) without cardiovascular disease, malignancy, chronic kidney disease and diabetes mellitus. Patients were divided into two groups vitamin D deficiency group (<20 ng/ml) and normal vitamin D group (≥20 ng/ml). Twenty-four-hour, daytime and nighttime ambulatory BP readings were recorded. Mobil-O-Graph ARC solver algorithm was used to evaluate arterial stiffness parameters of pulse wave velocity (PWV) (m/s), augmentation index normalized with 75/min heart rate (Alx@75).

Patients with vitamin D deficency had higher values of Alx@75 and PWV values (20.9 ± 9 vs. 16.8 ± 6.9, P = 0.018 and 8.37 ± 1.16 vs. 6.9 ± 0.9, P = 0.001, respectively) despite similar 24-hour ambulatory BP monitoring in both groups. Level of serum calcium was significantly higher in vitamin D deficiency group (9.5 ± 0.23 vs. 9.3 ± 0.12, P = 0.007). Nighttime SBP was higher in vitamin D deficiency group (133.2 ± 14.3 mmHg vs. 126.3 ± 17.2 mmHg; P = 0.03) and also, vitamin D deficiency group had non-dipping SBP pattern compared to normal Vitamin D group (P = 0.013).

Vitamin D deficiency is associated with increased arterial stiffness in newly diagnosed hypertensive patients in terms of increased PWV and Alx@75 values.

Chronic kidney disease (CKD) is associated with high cardiovascular risk. Prevalence of hypertension and hypertension-mediated organ damage (HMOD) increases with CKD progression. Nocturnal blood pressure (BP) is a strong predictor of cardiovascular complications. This cross-sectional study investigated the link between the diurnal BP profile and HMOD in nondiabetic CKD G1-G3b patients.

We investigated 109 CKD patients and 41 apparently healthy persons as controls. All subjects underwent 24-ambulatory blood pressure monitoring (ABPM), echocardiography with left ventricular mass index (LVMI) calculation and pulse wave velocity (PWV) measurement.

Hypertension was present in 84% of CKD patients. SBP-24 and DBP-24, SBP-day and DBP-day did not differ between CKD and controls. Significant differences were found in SBP-night and DBP-night. The nondipping BP profile (SBP-night/SBP-day ratio ≥0.9) was found in 62% of CKD patients and 32% of controls (P < 0.005). Nocturnal hypertension was found in 56% of CKD patients.
