To compare the effect of an intensity‐controlled exercise program (ICEP) and a nonintensity‐controlled exercise program (non‐ICEP) on the variables responsible for blood pressure regulation in hypertensive older adults. 95 hypertensive older adults (65.40 ± 7.48 years/22 males and 73 females) performed hemodynamic, functional fitness, and biochemical evaluations before and after 12 weeks of the multicomponent exercises which included walking, muscle strength, hydrogymnastics, Pilates, dynamic balance, agility, flexibility, and others. A significant improvement was observed in general functional fitness index (GFFI: p ≤ 0.000, d = 0.35), nitrite (NO2−: p ≤ 0.000, d = 0.49), systolic blood pressure (SBP: p ≤ 0.000, d = 0.65), diastolic blood pressure (DBP: p ≤ 0.013, d = 0.40), thiobarbituric acid reactive substances (TBARS: p ≤ 0.007, d = 0.78), activity of the endothelial superoxide dismutase enzyme (ecSOD: p ≤ 0.032, d = 0.41), double product (DP: p ≤ 0.015, d = 0.43), and waist‐hip ratio (WHR: p ≤ 0.000, d = 0.44) for ICEP. Only GFFI (p ≤ 0.047, d = 0.12), TBARS (p ≤ 0.000, d = 0.77), SOD (p ≤ 0.025, d = 0.25), DP (p ≤ 0.046, d = 0.26), and BMI (p ≤ 0.018, d = 0.02) presented better results in non‐ICEP. When the effect of the groups (controlled by age, BMI, and sex) was evaluated, an increase was observed in the NO2−, TBARS, and SOD and a reduction in the SBP and WHR variables in the ICEP group compared to the non‐ICEP group. Twelve weeks of engagement in a controlled‐intensity exercise program was enough to improve the level of functional fitness and variables regarding blood pressure regulation in hypertensive older adults. Conversely, physical exercise performed without intensity control was related to the limited effect on such variables. [ABSTRACT FROM AUTHOR]

Background: Self-reported adherence scales are widely used in research and practice because they are low in cost and easy to apply. A free version in Brazilian-Portuguese of the Simplified Medication Adherence Questionnaire (SMAQ) can be a useful alternative for determining the adherent behavior of hypertensive patients. Purpose: To translate and evaluate the psychometric properties of the Brazilian-Portuguese version of the SMAQ therapeutic adherence scale for patients with arterial hypertension. Patients and methods: A multicenter, cross-sectional study was conducted in five outpatient units in Maceió-AL and Aracaju-SE between January and July 2019. A total of 117 patients aged over 18 years using antihypertensive drugs were recruited. The cross-cultural adaptation followed international methodological recommendations. Internal consistency (Cronbach's alpha) was tested as a reliability parameter. Criterion and construct validity were verified by concurrent validation, exploratory factor analysis (EFA), and validation by known groups. Results: The participants had a mean age of 56.6 years (SD = 10.7 years); most were female (72.6%). The mean number of antihypertensives prescribed per patient was 1.87 (SD = 0.87). There were 79.5% (n = 86) of patients considered non-adherent. Internal consistency was satisfactory (Cronbach's alpha = 0.63). A satisfactory correlation coefficient was verified with the Morisky-Green-Levine test as an external criterion (r = 0.56, p < 0.001). The scale's sensitivity measured through known group validity was 75.3%, specificity 29.5%, positive predictive value 63.9%, and negative predictive value 41.9%. We identified two factors of the instrument's construct from EFA: specific medication-taking behaviors and barriers to adherence. The initial KMO measure of sampling adequacy was 0.691, and Bartlett's test of sphericity was significant (χ² = 118.342, p < 0.001). Conclusion: The Brazilian-Portuguese version of the SMAQ scale proved valid and reliable for determining adherence to the pharmacotherapy in hypertensive patients. It showed more ability to detect non-adherent patients but with low specificity, possibly influenced by high social desirability. [ABSTRACT FROM AUTHOR]

Background. Ageing is associated with structural changes in brain regions and functional decline in cognitive domains. Noninvasive tools for identifying structural damage in the brains of older adults are relevant for early treatment. Aims. This study aims to evaluate and compare the accuracy of the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA©) in identifying gray and white matter brain damage in older individuals with varying degrees of cognitive impairment. Methods. Ninety older adults (62 women) with an average age of 69 ± 7 years were enrolled and categorized as having no cognitive impairment (NCI), mild cognitive impairment (MCI), or moderate cognitive impairment (MoCI). Magnetic resonance imaging (MRI) was utilized to assess the number, volume, and distribution of brain damage. The Fazekas and Scheltens scales were applied to the brain MRIs, and inferential statistics were employed to compare variables among the groups. Results. Cognitive impairment was observed in 56.7% of the participants (95% confidence interval (CI): 46.4–66.4%), with thirty-six older adults (40%) classified as MCI and 15 (17%) as MoCI. Cognitive impairment and medial temporal lobe (MTL) atrophy were found to be associated (p = 0.001), exhibiting higher mean volume scales of the MTL atrophied area in the MoCI group (p < 0.001). The MMSE accurately revealed MTL atrophy based on the Scheltens (p < 0.05) and Fazekas (p < 0.05) scales. At the same time, the MoCA accurately identified periventricular white matter (PWM) abnormalities according to the Fazekas scale (p < 0.05). Conclusions. The MMSE and MoCA screening tools effectively identified gray and white matter brain damage in older adults with varying degrees of cognitive impairment. Lower MMSE scores are associated with MTL atrophy and lesions, and lower MoCA scores are related to PWM lesions. The concurrent use of MMSE and MoCA is recommended for assessing structural changes in distinct brain regions. [ABSTRACT FROM AUTHOR]

Objectives. To evaluate the associations between individuals with and without changes in components of metabolic syndrome (MetS) and demographic, nutritional, and lifestyle factors. Methods. A cross-sectional study was conducted with 224 individuals followed-up at a public hospital in Northeast Brazil. We used National Cholesterol Education Program-Adult Treatment Panel III (NCEP) criteria to diagnose MetS. We assessed components of MetS as dependent variables, while sex, age, food consumption, smoking, alcohol intake, physical activity, anthropometric parameters, and sleep hours were independent variables. Results. Comparing individuals with and without changes in components of MetS, the logistic regression models revealed that female sex was predictive of increased waist circumference and low HDL-c levels while advanced age was predictive of increased blood pressure and blood glucose levels. BMI emerged as a predictor for waist circumference and a protective factor for triglyceride levels. In addition, potassium intake, physical activity, and sleep duration were protective against decreased HDL-c, elevated triglyceride, and elevated blood pressure levels, respectively. Conclusion. This study demonstrated that sex, age, BMI, dietary potassium intake, physical activity, and hours of sleep are factors to be targeted in public health actions for prevention and treatment of MetS.

This study investigated the acute blood pressure (BP) effects of different exercise modalities in older adults with hypertension. Sixty volunteers were randomly assigned (n = 15/group) into different exercise protocols: resistance, bike, water-based exercise (WE), and a control session—all for ∼45 min. Clinic BP measurements were taken before, immediately after, and 15 and 30 min after protocols. The data were analyzed by one-way analysis of variance; generalized estimating equations, following Bonferroni post hoc (p <.05). Immediately after exercise, the systolic BP (SBP) increased in all exercise protocols (resistance exercise = Δ10.3, bike exercise = Δ5.8, WE = Δ9.5 mmHg; p <.001), while the diastolic BP was not altered. Afterward, the SBP reached the value observed before exercise. In Minute 30, only WE presented a significant reduction for SBP (WE = Δ−4.6 mmHg; p <.05). This study has important clinical implications in hemodynamic safety for acute BP increases immediately after exercises, as well as, in the SBP, reduction benefits for older adults with hypertension.

We have investigated the electrical characteristics of an AlGaAs/GaAs high electron mobility transistor, in which a layer of InAs self-assembled Quantum Dots (QDs) was inserted below the 2DEG channel. A Negative Differential Capacitance (NDC) appeared in the capacitance–voltage characteristics at a bias of 1 V and at low temperatures (even at room temperature) under different illumination powers using white light bulbs. This results in an increase in negative differential conductance with the increase in frequency and optical power. This also applies to the NDC except that it decreases with increasing frequency. The numerical simulation of the energy band structure of the device confirmed that the conduction band lowers to its minimum at a special bias value of 1 V. The numerical analysis of the evolution of the energy levels in the QD-HEMT follows the appearance of multiple capacitance peaks and their behavior with the gate voltage. [ABSTRACT FROM AUTHOR]

This study aimed to compare the effects of resistance training performed with low versus moderate loads on systemic resting blood pressure (BP) in older women. A total of 29 women (72.6 ± 5.1 years) were randomized into two groups: low load (LOW, n = 15) and moderate load (MOD, n = 14). An 8-week whole-body resistance training program was carried out 3 days/week (eight exercises, three sets, 10 or 15 repetition maximum). The LOW and MOD groups trained with a relative load of 15 and 10 repetition maximum, respectively. Outcome measures included resting systolic and diastolic BP. After 8 weeks, both groups presented significant changes (p <.05) in systolic BP (LOW = −3.0%; MOD = −4.6%) and mean BP (LOW = −1.9%; MOD = −3.1%). There was no change for diastolic BP in the posttest in both groups. The results suggest that low and moderate loads are equally effective for promoting decreases in resting BP in older women.

This study aimed to identify sociodemographic and clinical characteristics and factors associated with care transition in patients recovered from COVID-19. Cross-sectional study of quantitative approach with 49 patients and/or caregivers who were discharged from hospital to home in a university hospital. Three instruments were used to evaluate the transition of care: the sociodemographic questionnaire, the clinical questionnaire, and the Care Transition Measure. The analysis was performed using SPSS software, and the Mann–Whitney test was applied, with a significance level of p ≤ 0.005. Of the 49 participants, with a mean age of 50 years, the majority were males (59.2%), with more than 10 years of education. The main symptoms of COVID-19 were dyspnea (79.6%), followed by fatigue (75.5%) and fever (69.4%). The most prevalent comorbidity was hypertension (32.7%). There was an association between care transition and comorbidities (diabetes mellitus, obesity, and cancer) (p < 0.005). The study found that the transition of care for patients recovered with COVID-19 from hospital discharge to home was successful. However, the need for public policy implementation after hospital discharge in a pandemic setting is emphasized. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to compare the effects of combined training (CT) and multicomponent training (MT) on different health parameters in physically active women aged between 50 and 75 years. Method: The participants were randomly divided into two training groups (CT and MT), lasting 180 min per week, for 14 consecutive weeks of training with the level of physical activity, anthropometric measurements, blood pressure, strength, cardiorespiratory skills, coordination, flexibility, agility, and quality of life. Results: Participants who underwent CT and MT training showed positive responses regarding the assessment of body mass, waist circumference, lower limb resistance and strength, upper limb strength, and mental domain related to the quality of life. However, only participants undergoing CT were able to increase agility and cardiorespiratory capacities. Conclusion: 14 weeks of CT were more efficient to improve physical capacities in physically active women aged between 50 and 75 years when compared to MT. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to investigate the role of serum irisin level in predicting clinical outcome in heart failure (HF) patients with type 2 diabetes mellitus (T2DM). Methods: 153 T2DM patients with HF aged 41–62 years were prospectively recruited for the study. Serum levels of irisin and NT-proBNP were measured by ELISA. Laboratory tests including HbA1c, fasting glucose, blood creatinine, insulin, lipids and creatinine with estimation of GFR were performed along with echocardiography at baseline. The observation period was 56 weeks. Results: We identified 76 composite cardiovascular (CV) outcomes, which included CV death and death from all causes, resuscitated cardiac death, non-fatal/fatal acute myocardial infarction or stroke, and HF hospitalization. Therefore, the entire patient cohort was divided into 2 groups with (n = 76) and without (n = 77) composite CV outcomes. We found that the concentrations of NT-proBNP were higher in HF patients with T2DM who had a CV composite outcome than in patients without CV composite outcome (p = 0.001). In contrast, the relationship was exactly reversed for irisin, as HF and T2DM patients with CV composite outcome had significantly lower irisin levels (p = 0.001). Unadjusted multivariate Cox regression analyses showed that LVEF < 40%, LAVI > 39 ml/m2, NT-proBNP > 2,250 pmol/ml, and irisin < 6.50 ng/ml were the strongest predictors of CV outcomes in HF patients with T2DM. After adjustment for LVEF, serum levels of NT-proBNP and irisin remained independent predictors of end points. Furthermore, divergence of Kaplan-Meier curves pointed out that patients with NT-proBNP > 2,250 pmol/ml and irisin < 6.50 ng/ml had worse prognosis than those with any other compartment of the bomarkers' levels. Conclusion: Adding irisin to NT-proBNP significantly improved discriminative value of the whole model. HF patients with T2DM had significantly worse clinical outcomes when showing the constellation NT-proBNP > 2,250 pmol/ml and irisin < 6.50 ng/ml, respectively, in comparison to patients with opposite trends for both biomarkers.

Purpose: To measure the effects of the NIC intervention fall prevention on the magnitude of the NANDA‐I Risk for falls' risk factors and of NOC indicators related to falls in older adults with arterial hypertension. Background: Nurses can use nursing taxonomies to provide effective care in preventing falls in specific populations. Methods: Clinical, randomized, open, parallel, and multicenter trial following the CONSORT recommendations for nonpharmacological trials. The clinical trial was registered. The research was conducted with 118 older adults allocated to intervention and control groups and matched by sex and age. The intervention was conducted in the participants' homes in three different moments and consisted of nursing activities belonging to the NIC Fall prevention and implemented with the aid of a protocol with operational definitions. Findings: Three months after the intervention, there was a significant intergroup difference in the frequency of Risk for falls and of the following factors/conditions: cluttered environment, unfamiliar setting, exposure to unsafe weather‐related condition, insufficient anti‐slip material in the bathroom, history of falls, acute illness, orthostatic hypotension, hearing impairment, and impaired vision. There was also a positive change in the magnitude of the following NOC indicators: risk control, cognitive orientation, knowledge: fall prevention, safe home environment, comfort level, vision compensation behavior, and leisure participation. Conclusions: The NIC intervention Fall prevention was effective in modifying risk factors belonging to Risk for falls and NOC indicators related to falls in older adults. Implications for nursing practice: The tested intervention is important and should be instituted, mainly by nurses from primary care services who make home visits to older adults.

This study aimed to determine whether body fat distribution and physical fitness would be associated with risk factors for cardiovascular diseases (CVDs) in post-menopausal females. Android fat distribution were more likely to have altered total cholesterol (TC), high-density lipoprotein (HDL-C), triglycerides (TG), glycemic levels (GL) body fat percentage (%BF), and body mass index (BMI), and those with inadequate physical fitness showed clear alterations in TC, HDL-C, and TG. Gynoid fat distribution group fared better regarding CVD risk. In conclusion, adequate physical fitness demonstrates a protective factor against CVDs, with the greatest benefit to those with gynoid fat distribution. [ABSTRACT FROM AUTHOR]

Objectives: Excessive adiposity is associated with cardiovascular disease (CVD). Anthropometric indices are useful in screening individuals at higher risk for these diseases. However, there are no studies that show which of these indices has the best discriminatory power among Afro‐descendant Brazilian women. The objective of this study was to assess the accuracy of anthropometric indices in identifying risk factors for CVD in Afro‐descendant Brazilian women and define the one most suitable for use under the operating conditions prevailing in Quilombola communities. Methods: A household random sample of 1661 women descendants of African slaves were analyzed. The anthropometric predictors analyzed were waist circumference (WC), body mass index, waist‐to‐height ratio, conicity index (C‐index), body shape index, and percentage of body fat (%BF; estimated by bioimpedance). The assessed risk factors for CVD were arterial hypertension, diabetes mellitus, and dyslipidemias (hypertriglyceridemia; hypercholesterolemia; low high‐density lipoprotein). To identify the statistical significance between the differences in the areas under the ROC curves (AUC) obtained with the different predictors and outcomes, was used the Bonferroni test adjusted for multiple analyses by the Sidak method. Results: The AUC obtained with WC was higher (p <.05) or similar (p >.05) to those obtained with the other predictors 29 times out of 30 possibilities (six predictors x five outcomes). Only the AUC obtained with C‐index in identifying hypercholesterolemia was significantly higher than that with WC. Conclusion: Due to its accuracy and greater operational simplicity, WC was the most adequate predictor for identifying Afro‐descendant women at greatest risk for CVD. [ABSTRACT FROM AUTHOR]

Hyperuricemia (HU) has been associated with cardiovascular risk and metabolic syndrome (MS) worldwide. However, inconsistencies about this relation are still reported, and it is not clear whether hyperuricemia is an independent risk factor for MS. The aim of this study was to determine hyperuricemia associations with systemic hypertension and MS in women from northeast Brazil. The study included 301 women. Hyperuricemia was considered for serum uric acid (SUA) ≥6 mg/dL. Insulin resistance (IR) was measured by TyG index (TyG ≥ 4.55). Fisher test and Multivariate logistic regression analyses estimated the association between hyperuricemia (or SUA level) and systemic hypertension and MS. Hyperuricemia association with systemic hypertension was independent of age, body-mass index (BMI), smoking and alcoholism (OR: OR: 4.6050; p =.000256), and MS components (OR: 4.1296; IC95% 1.8330_9.3033; p =.000621). Hyperuricemia increased risk of systemic hypertension by 4,6 -fold. SUA level was associated with MS, independently of other classic component factors of the syndrome (OR:1.34, p =.0129). Hyperuricemia and high SUA levels were associated with MS and systemic hypertension. Effect of hyperuricemia in systemic hypertension is independent of age, BMI, lifestyle, and MS factors. SUA levels are independently associated with MS. [ABSTRACT FROM AUTHOR]

Patients with Parkinson's disease (PD) have difficulties while performing dual-task activities, a condition present in everyday life. It is possible that strategies such as transcranial Direct Current Stimulation (tDCS) can be associated with motor training enriched with dual-task training to improve the performance of two concurrent tasks. Currently, it is unclear whether specific tasks and clinical conditions of PD patients have different results after the intervention. Therefore, the proposed randomized controlled trial will examine task-dependency in enhancing the effects of tDCS-linked rehabilitation training on PD and the relationships between baseline outcomes in responders and non-responders to therapy. Fifty-six patients with Parkinson's disease will be recruited to participate in this controlled, double-blind randomized multicentric clinical trial. Patients in modified Hoehn & Yahr stage 1.5–3, age between 40 and 70 years will be included. Subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform treadmill gait training associated with dual task exercises+tDCS, while the CG will only engage in treadmill gait training+tDCS. Blinded testers will assess patients before and after 12 intervention sessions and after a 4-week follow-up period. All patients will undergo a screening and an initial visit before being assessed for primary and secondary outcomes. The primary outcome measure is functional mobility measured by Timed Up and Go Test. Secondary outcomes include cognitive function, participation, motor function and body function and structure. This study will evaluate the effectiveness of an intervention protocol with tDCS, dual-task training and gait training in patients with PD. The study will also highlight the clinical factors and variability between individuals that could interfere in the training of a specific task and influence the therapeutic effect.

Hypertensive older adults have reduced blood flow and oxygen supply as compared to normotensive individuals. These negative adaptations can negatively impact muscle function. Although the vascular consequences of systemic arterial hypertension (SAH) have been extensively discussed, the literature on functional fitness (FF) in hypertensive older persons is limited. The objective of the present study was to investigate the influence of resting blood pressure (BP) on functional fitness in hypertensive as compared to normotensive older women. A total of 48 older women were included according to their resting BP: 24 from the normal BP group (GNBP, 70.5 ± 7.4 years) and 24 from the high BP group (GHBP, 71.0 ± 6.8 years). Anthropometric measurements and FF (30s Chair Stand, Arm Curl, Chair Sit and Reach and 8-Foot Up-and-Go) were investigated. The comparison between groups revealed that the GNBP had a higher number of repetitions in the 30s chair stand test (p=0.007, d=0.618) as compared to the GHPB. Hypertensive older women have lower values of lower limb muscle strength compared to normotensive older women. Therefore, functional tests that measure muscle strength of lower limbs may be adapted for this population. [ABSTRACT FROM AUTHOR]

Cardiovascular diseases are responsible for high morbidity and mortality rates worldwide. Among treatment options, medicinal plants are frequently used, especially in developing countries, such as Brazil. Despite social development that has been observed in the last decades, the use of medicinal plants is still driven by popular knowledge, especially by healers. The present study sought to identify medicinal species that are used for the treatment of cardiovascular diseases by healers in the microregion of Francisco Beltrão, Paraná, Brazil. The snowball technique was used to select informants, and data were collected through interviews. The research was performed in two stages: (1) a structured interview and (2) the collection and botanical identification of the species that were mentioned by the healers. Medicinal plants were classified into the following categories of cardiovascular agents: hypotensive and antihypertensive agents, lipid-lowering agents, diuretic agents, and cardiotonic agents. To analyze the data, the frequency was determined, Spearman correlations were calculated, and the informant consensus factor (ICF) and use value were obtained. Some characteristics, such as female gender and old age, were associated with knowledge about medicinal plants. Overall, 77 different species and 149 medicinal uses were cited by the healers. With regard to categories of use, the highest number of species was found among lipid-lowering plants, and the highest ICF was found for species that are used as cardiotonics. Moreover, a literature review indicated that among the cited species, several still lack studies that have proven their effects on the cardiovascular system. The traditional use of medicinal plants for the treatment of cardiovascular diseases is broad in the study regions. The present results are important for clarifying popular knowledge in this region and providing a framework for selecting species with potential for the development of new pharmacological studies.

Purpose: This paper aims to verify the effect of 12 weeks of grape juice (GJ) consumption associated with aerobic exercise on the variation of the hypertensive elderly pressure. Design/methodology/approach: A total of 45 hypertensive elderly of both sexes were distributed into: control group (CG, n = 10), exercise group (EG, n = 10), juice group (JG, n = 12) and juice and exercise group (JEG, n = 13). Blood pressure and heart rate were checked weekly before exercise in JG and JEG, and before and after intervention in all groups, with JG and JEG supplemented with 200 mL of GJ. Three weekly sessions of moderate walking were applied. Findings: There was a reduction in EG, JG and JEG for systolic pressure and diastolic only for JG and JEG. The GJ consumption to the practice of aerobic exercise provided reductions in the arterial pressure of hypertensive, in addition to stabilization of the diastolic pressure. Research limitations/implications: Although the objective of the study was to compare the effect and value of intervention with controls, the study had no intervention in food consumption, which could have led to more significant results. There was a limitation in the control drink, leading the study not to be blind, which may have impaired the results. However, it is probably not a bias, as the groups were divided by residence area, and therefore, had no direct contact with the other groups. Another limitation was that the sample size was still small, which would lead to more reliable results. Finally, although the existing limitations cannot be disregarded, the results of this research are very promising, especially when the objective is the effect of GJ and aerobic exercise on blood pressure, with the possibility of implementing supplemental GJ and the inclusion or not of exercise to the hypertensive elderly. Originality/value: The paper deals with the benefits of GJ consumption associated with aerobic physical exercise on the blood pressure of elderly hypertensive patients. Considering that GJ along with physical exercise was enough to reduce the blood pressure of hypertensive elderly, this may be a new model to be used to reduce and/or control blood pressure, and GJ and the exercise to be part of the daily life of the population.

Aim. The present study compared the acute effects of aerobic (AER), resistance (RES), and combined (COM) exercises on blood pressure (BP) levels in people with resistant hypertension (RH) and nonresistant hypertension (NON-RH). Methods. Twenty patients (10 RH and 10 NON-RH) were recruited and randomly performed three exercise sessions and a control session. Ambulatory BP was monitored over 24 hours after each experimental session. Results. Significant reductions on ambulatory BP were found in people with RH after AER, RES, and COM sessions. Notably, ambulatory BP was reduced during awake-time and night-time periods after COM. On the other hand, the effects of AER were more prominent during awake periods, while RES caused greater reductions during the night-time period. In NON-RH, only RES acutely reduced systolic BP, while diastolic BP was reduced after all exercise sessions. However, the longest postexercise ambulatory hypotension was observed after AER (~11 h) in comparison to RES (~8 h) and COM (~4 h) exercises. Conclusion. Findings of the present study indicate that AER, RES, and COM exercises elicit systolic and diastolic postexercise ambulatory hypotension in RH patients. Notably, longer hypotension periods were observed after COM exercise. In addition, NON-RH and RH people showed different changes on BP after exercise sessions, suggesting that postexercise hypotension is influenced by the pathophysiological bases of hypertension.

The following narrative review addresses the relationship between physical activity and exercise with cardiovascular health, focusing primarily on the following risk factors for atherosclerosis: hypertension, dyslipidemia, and vascular function. Cardiovascular diseases are intimately associated with mortality and morbidity, and current societal organization contributes to the incidence of cardiovascular events. A worldwide epidemiological transition to cardiovascular deaths was observed in the last century, with important decrements in physical activity and diet quality. An atherogenic environment started to be the new normal, with risk factors such as dyslipidemia, hypertension, and endothelial dysfunction observed in great portions of the population. Exercise is an important tool to improve overall health. For hypertension, a great amount of evidence now puts exercise as an effective therapeutic tool in the treatment of this condition. The effects of exercise in modifying blood lipid–lipoprotein are less clear. Despite the rationale remaining solid, methodological difficulties impair the interpretation of possible effects in these variables. Vascular function, as assessed by flow-mediated dilatation, is a good measure of overall vascular health and is consistently improved by exercise in many populations. However, in individuals with hypertension, the exercise literature still needs a further description of possible effects on vascular function variables. Physical activity and exercise are associated with improved cardiovascular health, especially with reduced blood pressure, and should be encouraged on the individual and population level. Evidence regarding its effects on blood lipids and flow-mediated dilatation still need solid landmark studies to guide clinical practice. [ABSTRACT FROM AUTHOR]
