Childhood obesity has reached epidemic proportions and is linked to hypertension among African American youth. Optimistic bias influences behavior of youth causing them to underestimate their susceptibility to negative health outcomes. This study explored adolescent behaviors and prevalence of high blood pressure and obesity in a school district. We examined the relationship between individual health risk practices and optimistic bias on health outcomes; 433 African American high school students were administered a survey and had their obesity and blood pressure measured by the school nurse...

PURPOSE: Previous studies report abnormal muscle metaboreflex control of muscle sympathetic nerve activity (MSNA) in obesity, hypertension, and heart failure. We hypothesized that obstructive sleep apnea (OSA) is associated with augmented metaboreflex control of MSNA. METHODS: Thirty-one sedentary individuals with no comorbidities (age = 52±1 y, body mass index = 28±1 kg/m) without (control, n = 14) and with OSA (n = 17) defined by polysomnography, underwent echocardiography...

Heart failure (HF) is a major health problem. Hypertension is an important cause of HF. Most hypertensive patients have some degree of left ventricular (LV) diastolic dysfunction. The 6-minute walk test (6MWT) provides objective data about the exercise tolerance. We aimed to find the association between the degree of LV diastolic dysfunction and the functional capacity assessed by 6MWT in hypertensive patients. The study included 200 asymptomatic hypertensive patients. All patients had undergone full history taking, complete clinical examination, electrocardiography, echocardiography for assessment of LV dimensions, systolic and diastolic dysfunction, and 6MWT...

Essential hypertension is a major health problem causing excess cardiovascular morbidity and mortality. Management of essential hypertension consists of pharmacological and nonpharmacological interventions. In order to prevent and/or treat hypertension, parameters like nutrition, body weight, and physical exercise should be evaluated and taken under consideration for improvement. A large body of evidence clearly support that the role of salt, alcohol, fruits, and vegetables is important for high blood pressure...

In view of the enormous popularity of mass sporting events such as half-marathons, the number of patients with exertional rhabdomyolysis or exercise-induced heat stroke admitted to intensive care units (ICUs) has increased over the last decade. Because these patients have been reported to be at risk for malignant hyperthermia during general anesthesia, the intensive care community should bear in mind that the same risk of life-threatening rhabdomyolysis is present when these patients are admitted to an ICU, and volatile anesthetic sedation is chosen as the sedative technique...

BACKGROUND: Clinic post-exercise hypotension (PEH) is different after aerobic exercise performed in the morning and in the evening. Thus, ambulatory PEH should also differ after exercises conducted at different times of day. However, because of the circadian pattern of BP, ambulatory PEH should be assessed considering a control condition. Thus, this study was designed to verify the effects of morning and evening exercises on post-exercise ambulatory BP averages and circadian parameters by comparing responses obtained at each time of day after an exercise and a control session...

To evaluate whether captopril (3×50 mg/day) potentiates post-resistance exercise hypotension (PREH) in hypertensives (HT), 12 HT men received captopril and placebo for 4 weeks each in a double-blinded, randomized-crossover design. On each therapy, subjects underwent 2 sessions: Control (C - rest) and Resistance Exercise (RE - 7 exercises, 3 sets to moderate fatigue, 50% of 1 RM -repetition maximum). Measurements were taken before and after 30-60 min (Post1) and 7 h (Post2), and ambulatory blood pressure (BP) was monitored for 24 h...

Favoring correct lifestyles is the most important measure to contrast cardiovascular diseases and the epidemic of high cardiovascular risk conditions, such as obesity, diabetes, and hypertension. Lifestyle is a broad expression that includes diet, physical exercise, and psychological and socio-economic factors, each of which must be taken into due consideration because of their intertwining influences, which may be a barrier to healthy changes at both the individual and population levels. While physical activity has probably received less attention in the last decades, it is likely the most important among the modifiable risk factors for cardiovascular diseases...

The etiology of hypertension, the world's biggest killer, remains poorly understood, with treatments targeting the established symptom, not the cause. The development of hypertension involves increased sympathetic nerve activity that, in experimental hypertension, may be driven by excessive respiratory modulation. Using selective viral and cell lesion techniques, we identify adrenergic C1 neurons in the medulla oblongata as critical for respiratory-sympathetic entrainment and the development of experimental hypertension...

INTRODUCTION: U.S. Latinas do not engage in sufficient leisure-time physical activity. This study examined whether adding promotor-facilitated healthy lifestyle classes to an exercise intervention would promote exercise session attendance and improve health indicators. METHODS: The Familias Sanas y Activas II (Healthy and Active Families II) study used a within-subjects, longitudinal design, with measures at baseline and at 6 and 12 months post-baseline. The intervention was developed by the San Diego Prevention Research Center and implemented between May 2011 and June 2014 in South San Diego County...

We examined whether a change in posterior cerebral artery flow velocity (PCAv) reflected the posterior cerebral blood flow, in healthy subjects, during both static and dynamic exercise. PCAv and vertebral artery (VA) blood flow, as an index of posterior blood flow, were continuously measured during an exercise trial, using transcranial Doppler (TCD) ultrasonography and Doppler ultrasound, respectively. Static handgrip exercise significantly increased both PCAv and VA blood flow. Increasing intensity of dynamic exercise further increased VA blood flow from moderate exercise, while PCAv decreased to almost resting level...

Anesthesiologists frequently see asymptomatic patients with diastolic dysfunction or heart failure for various surgeries. These patients typically show normal systolic function but abnormal diastolic parameters in their preoperative echocardiographic evaluations. The symptoms that are sometimes seen are similar to those of chronic obstructive pulmonary disease. Patients with diastolic dysfunction, and even with diastolic heart failure, have the potential to develop a hypertensive crisis or pulmonary congestion...

Pulmonary arterial hypertension (PAH) is characterized by vasoconstriction and proliferative obstruction of pulmonary vessels, which promotes a progressive increase in pulmonary vascular resistance (PVR). The effect of exercise training on oxidative stress, metabolism, and markers of nitric oxide (NO) and endothelin-1 (ET-1) was analyzed in the lung tissue of rats with PAH induced by monocrotaline (MCT).Twenty-four Wistar rats were divided into four groups (5-7 animals): sedentary control (SC), sedentary MCT (SM), trained control (TC), and trained MCT (TM)...

BACKGROUND: Recently, the IMPRES study revealed that systemic imatinib improves exercise capacity in patients with advanced pulmonary arterial hypertension. Imatinib blocks the tyrosine kinase activity of the platelet-derived growth factor (PDGF)-receptor (PDGFR), acts antiproliferative and relaxes pulmonary arteries. However so far, the relaxant effects of imatinib on pulmonary veins (PVs) and on the postcapillary resistance are unknown, although pulmonary hypertension (PH) due to left heart disease (LHD) is most common and primarily affects PVs...
