Hipertension y Riesgo Vascular | Year: 2014

Objective: To analyze the relationship between the circadian pattern of 24. hour ambulatory blood pressure and regular physical activity in hypertensive patients. Material and methods: A cross-sectional study that included 552 hypertensive patients from EVIDENT study (mean age 61 ± 55. years, 49.5% women) was performed. Ambulatory blood pressure was measured with a radial tonometer (pro-B device) and physical activity was assessed with an accelerometer Actigraph GT3X (counts/min) for 7 days. Results: Patients with dipper circadian pattern performed more regular physical activity than non-dipper patients. The measures of physical activity (counts/min) showed negative correlation with the night/day systolic and diastolic blood pressures ratio (ρ = -227 and ρ = -205, P < .001), respectively. This association remained in the multiple linear regression after adjusting for confounders (β = -016, P < .001). In the logistic regression, considering the circadian pattern as the dependent variable (1: dipper, 0: no dipper), the odds ratio for third tertile of counts/minute, compared to the first one was 2.80 (95%. CI: 1.73-4.51, P < .001) after adjusting for confounding variables. Conclusions: Physical activity assessed by accelerometer was associated with increased nocturnal blood pressure and, consequently, a lower night/day systolic and diastolic blood pressure ratio in hypertensive patients.

Atherosclerosis | Year: 2015

Objective: Arterial stiffness is a contributor to the development of atherosclerosis and cardiovascular disease. The aim of the study was to analyse the relationship between sedentary behaviour and arterial stiffness in a Spanish adult population. Methods: This cross-sectional study included 1365 subjects belonging to the EVIDENT project. Physical activity and sedentary behaviour were measured objectively over 7 days using ActiGraph accelerometers. Thresholds of 10 consecutive minutes were used to estimate the daily sedentary time in bouts ≥10 min. Each interruption in sedentary time (counts/min ≥100) was considered a break. Arterial stiffness was evaluated using the B-pro device through the following indicators: radial Augmentation Index (rAIx), Ambulatory Arterial Stiffness Index (AASI), and central and peripheral pulse pressure (PP). Results: We found a positive relationship between central and peripheral pulse pressure (office, 24 h, awake and sleep PP) and total sedentary time. These arterial stiffness parameters were also associated with sedentary time in bouts ≥10 min. Significance disappeared in both cases, however, after adjusting for MVPA and breaks per sedentary hour. Adults who reported fewer breaks per sedentary hour (25th percentile < 2 n/day) had higher levels of AASI, awake and sleep PP. Conclusions: In a medium-sized sample of adult attenders of community clinics our data showed that it seems to be important to avoid prolonged uninterrupted periods of sedentary time. © 2015 Elsevier Ireland Ltd.

Background: The present study analyses the relation between smoking status and the parameters used to assess vascular structure and function. Methods: This cross-sectional, multi-centre study involved a random sample of 1553 participants from the EVIDENT study. Measurements: The smoking status, peripheral augmentation index and ankle-brachial index were measured in all participants. In a small subset of the main population (265 participants), the carotid intima-media thickness and pulse wave velocity were also measured. Results: After controlling for the effect of age, sex and other risk factors, present smokers have higher values of carotid intima-media thickness (p = 0.011). Along the same lines, current smokers have higher values of pulse wave velocity and lower mean values of ankle-brachial index but without statistical significance in both cases. Conclusions: Among the parameters of vascular structure and function analysed, only the IMT shows association with the smoking status, after adjusting for confounders. © 2013 Recio-Rodriguez et al.; licensee BioMed Central Ltd.

Objectives: The use of brief screening tools to identify inactive patients is essential to improve the efficiency of primary care-based physical activity (PA) programs. However, the current employment of short PA questionnaires within the Spanish primary care pathway is unclear. This study evaluated the validity of the Spanish version of a Brief Physical Activity Assessment Tool (SBPAAT). Methods: A validation study was carried out within the EVIDENT project. A convenience sample of patients (n = 1,184; age 58.9±13.7 years; 60.5% female) completed the SBPAAT and the 7-day Physical Activity Recall (7DPAR) and, in addition, wore an accelerometer (ActiGraph GT3X) for seven consecutive days. Validity was evaluated by measuring agreement, Kappa correlation coefficients, sensitivity and specificity in achieving current PA recommendations with the 7DPAR. Pearson correlation coefficients with the number of daily minutes engaged in moderate and vigorous intensity PA according to the accelerometer were also assessed. Comparison with accelerometer counts, daily minutes engaged in sedentary, light, moderate, and vigorous intensity PA, total daily kilocalories, and total PA and leisure time expenditure (METs-hour-week) between the sufficiently and insufficiently active groups identified by SBPAAT were reported. Results: The SBPAAT identified 41.3%sufficiently active (n = 489) and 58.7% insufficiently active (n = 695) patients; it showed moderate validity (k = 0.454, 95% CI: 0.402-0.505) and a specificity and sensitivity of 74.3%and 74.6%, respectively. Validity was fair for identifying daily minutes engaged in moderate (r = 0.215, 95% CI:0.156 to 0.272) and vigorous PA (r = 0.282, 95% CI:0.165 to 0.391). Insufficiently active patients according to the SBPAAT significantly reported fewer counts/minute (-22%), fewer minutes/day of moderate (-11.38) and vigorous PA (-2.69), spent fewer total kilocalories/day (-753), and reported a lower energy cost (METs-hour-week) of physical activities globally (-26.82) and during leisure time (-19.62). Conclusions: The SBPAAT is a valid tool to identify Spanish-speaking patients who are insufficiently active to achieve health benefits. Copyright © 2015 Puig-Ribera et al.

Background. Quality of life (QoL) decreases as heart failure worsens, which is one of the greatest worries of these patients. Physical exercise has been shown to be safe for people with heart failure. Previous studies have tested heterogeneous exercise programs using different QoL instruments and reported inconsistent effects on QoL. The aim of this study is to evaluate the effectiveness of a new exercise program for people with heart failure (EFICAR), additional to the recommended optimal treatment in primary care, to improve QoL, functional capacity and control of cardiovascular risk factors. Methods/Design. Multicenter clinical trial in which 600 patients with heart failure in NYHA class II-IV will be randomized to two parallel groups: EFICAR and control. After being recruited, through the reference cardiology services, in six health centres from the Spanish Primary Care Prevention and Health Promotion Research Network (redIAPP), patients are followed for 1 year after the beginning of the intervention. Both groups receive the optimized treatment according to the European Society of Cardiology guidelines. In addition, the EFICAR group performs a 3 month supervised progressive exercise program with an aerobic (high-intensity intervals) and a strength component; and the programme continues linked with community resources for 9 months. The main outcome measure is the change in health-related QoL measured by the SF-36 and the Minnesota Living with Heart Failure Questionnaires at baseline, 3, 6 and 12 months. Secondary outcomes considered are changes in functional capacity measured by the 6-Minute Walking Test, cardiac structure (B-type natriuretic peptides), muscle strength and body composition. Both groups will be compared on an intention to treat basis, using multi-level longitudinal mixed models. Sex, age, social class, co-morbidity and cardiovascular risk factors will be considered as potential confounding and predictor variables. Discussion. A key challenges of this study is to guarantee the safety of the patients; however, the current scientific evidence supports the notion of there being no increase in the risk of decompensation, cardiac events, hospitalizations and deaths associated with exercise, but rather the opposite. Safety assurance will be based on an optimized standardised pharmacological therapy and health education for all the participants. Trial Registration.
