“…36 Previously, no differences in LF and HF frequencies were reported between SED tertiles in hypertensive patients regardless of sex. 37 A recent study reported a small negative association with LF and leisure time sitting but after adjustments the association became non-significant. 25 The LF/HF ratio has been considered as a rather controversial measure, with the argument being that LF power would reflect sympathetic outflow only poorly.…”

“…LF/HF ratio has been used to describe sympatho‐vagal balance; LF power has been suggested to be generated by sympathetic nervous system and HF power by parasympathetic nervous system, and therefore, low LF/HF ratio would reflect parasympathetic dominance .

Prolonged bouts of sedentary time and cardiac autonomic function in midlife

Excessive sedentary time (SED) and long SED bouts are associated with cardiovascular diseases (CVD) and increased mortality. Low heart rate variability (HRV), indicating autonomic dysfunction, increases mortality and CVD morbidity. Information about the association between prolonged SED and HRV is lacking. The aim was to assess the relationship between SED bouts and HRV. Physical activity (PA), SED, HRV, and cardiorespiratory fitness (CRF) were collected from a birth‐cohort sample (n = 4150) at 46 years. PA and SED were measured for 14 days with an activity monitor (Polar Active, Polar Electro, Finland). SED accumulating in bouts of at least 30 and 60 minutes (SED30, SED60) was calculated. Linear regression was used to study the relationship between prolonged SED and HRV accounting for CRF, PA, and health covariates. Higher SED60 and in women SED30 were associated with higher root mean square of differences in R‐R intervals (rMSSD) after adjustments (β = .082‐.104). In women, higher SED60 was associated with lower ratio between low‐ and high‐frequency powers (β = −.060). Sedentary bouts were not associated with resting HR or post‐exercise HR recovery. A positive relationship between SED bouts and rMSSD independent of PA and CRF was found, prolonged SED being positively associated with cardiac parasympathetic activity in midlife.

Background: Hypertensive patients present, in addition to worse cardiovascular health, lower health-related quality of life compared to normotensive subjects. Factors such as functional capacity, functional status, pain, participation in social activities, mental and emotional health, fatigue and energy level, along with perception of general health, seem to be relevant for evaluation in this population. However, evidence is unclear in hypertensive patients. Objective: To analyze the factors associated with quality of life in hypertensive patients. Methods: Forty-five patients were recruited. The dependent variables of the present study are the quality of life domains. Demographic data and clinical conditions were considered independent variables. The Medical Outcomes Short-Form Health Survey (SF-36) questionnaire was used to measure quality of life. Handgrip strength, blood pressure and anthropometric indicators were evaluated. Crude and adjusted linear regression analysis was used. Results: It was verified that education level, body mass index and muscle strength were associated with the functional capacity domain (p < 0,05), whereas systolic blood pressure was associated with the physical domain (p < 0,05). Women presented lower quality of life on the pain domain compared to men and educational level was associated with the social domain (p < 0,05). Conclusion: Hypertensive patients with lower levels of body mass index, higher levels of education and muscle strength presented a better quality of life on the physical domain, while the social aspects presented a positive relationship with education level. Women presented a worse quality of life on the pain domain compared to men.

“…Recruitment strategies have been described elsewhere. (14) Inclusion criteria were as follows: age over 40 years, diagnosis of hypertension, (15) and use of antihypertensive drugs for at least 3 months prior to the study. Diabetic patients, patients with a previous diagnosis of cardiovascular disease (e.g., ischemic heart disease, heart failure, coronary artery disease, peripheral arterial disease or stroke), or with physical disabilities, or involved in regular physical activity programs were not included.…”

Objective: To investigate the efficacy of a behavior change program named Vida Ativa Melhorando a Saúde on cardiovascular parameters in hypertensive patients. Methods: Ninety hypertensive patients aged over 40 years were randomly allocated to one of two groups: Vida Ativa Melhorando a Saúde or Control (n=45 respectively). Patients in the Vida Ativa Melhorando a Saúde group took part in a behavior change program aimed to encourage changes in physical activity levels and eating habits, according to the Social Cognitive Theory. The program consisted of 90-minute weekly group meetings conducted by a physical therapist and a dietitian. One chapter of the educational material (workbook) provided was discussed per meeting. Participants in the Control Group attended a single educative lecture on lifestyle changes. Brachial and central blood pressure, arterial stiffness and endothelial function parameters were measured preand post-intervention. Results: Vida Ativa Melhorando a Saúde led to reduction of brachial (131.3±15.8mmHg to 125.1±17.3mmHg; p<0.01) and central (123.6±16.3mmHg to 119.0±20.6mmHg; p=0.02) systolic and brachial diastolic (123.6±16.3mmHg to 119.0±20.6mmHg; p<0.01) blood pressure values, and improvement of post-occlusive reactive hyperemia (from 5.7±2.5mL•100mL −1 to 6.5±2.1mL•100mL −1 tissue•min −1; p=0.04). No changes in body composition, heart rate and arterial stiffness parameters were detected in both groups (p>0.05). Conclusion: Vida Ativa Melhorando a Saúde program improved blood pressure and microvascular reactivity in hypertensive patients.
