IntroductionMetabolic syndrome (MS) is a set of cardiovascular risk factors and type 2 diabetes, responsible for a 2.5-fold increased cardiovascular mortality and a 5-fold higher risk of developing diabetes.Objectives1-to evaluate the prevalence of MS in individuals over 18 years associated with age, gender, socioeconomic status, educational levels, body mass index (BMI), HOMA index and physical activity; moreover, to compare it to other studies; 2-to compare the prevalence of elevated blood pressure (BP), high triglycerides and plasma glucose levels, low HDL cholesterol and high waist circumference among individuals with MS also according to gender; 3-to determine the number of risk factors in subjects with MS and prevalence of complications in individuals with and without MS aged over 40 years.MethodsA cross-sectional study of 1369 Individuals, 667 males (48.7%) and 702 females (51.3%) was considered to evaluate the prevalence of MS and associated factors in the population.ResultsThe study showed that 22.7% (95% CI: 19.4% to 26.0%) of the population has MS, which increases with age, higher BMI and sedentary lifestyle. There was no significant difference between genders until age ≥70 years and social classes. Higher prevalence of MS was observed in lower educational levels and higher prevalence of HOMA positive among individuals with MS. The most prevalent risk factors were elevated blood pressure (85%), low HDL cholesterol (83.1%) and increased waist circumference (82.5%). The prevalence of elevated BP, low HDL cholesterol and plasma glucose levels did not show significant difference between genders. Individuals with MS had higher risk of cardiovascular complications over 40 years.ConclusionThe prevalence of MS found is similar to that in developed countries, being influenced by age, body mass index, educational levels, physical activity, and leading to a higher prevalence of cardiovascular complications after the 4th decade of life.

Hypertensive crisis (HC) stands out as one type of acute elevation in blood pressure (BP) and can manifest as hypertensive emergency (HE-with target-organ damage (TOD)) or hypertensive urgency (HU-without TOD), usually accompanied by levels of diastolic BP X120 mm Hg. The aim of this study was to characterize the clinical-epidemiological profile of HC over the course of 1 year in a university reference hospital and perform a review of the literature. The study was a cross-sectional study, conducted over a period of 1 year (2006) in 362 patients who presented for treatment at the emergency hospital with HC, as described above. Among all patients examined, 231 individuals met the criteria for HE and 131 met the criteria for HU. Patients with HE were older (Po0.001) and more sedentary (P¼0.026) than those with HU. Furthermore, fewer HE patients than HU patients had previously undergone antihypertensive treatment (P¼0.006). The groups did not differ regarding BP levels, gender, smoking or body mass index. Dyspnea (41.1%), thoracic pain (37.2%) and neurological deficit (27.2%) were common signs/symptoms in those with HE. Meanwhile, in the group with HU, we most frequently found headache (42.0%), thoracic pain (41.2%) and dyspnea (34.3%). Among the forms of HE, we most frequently observed acute lung edema (30.7%), myocardial infarction/unstable angina (25.1%), and ischemic (22.9%) and hemorrhagic (14.8%) stroke. HC is a clinical entity associated with high morbidity in the emergency room. Individuals with HE are older and sedentary and have lower rates of antihypertensive treatment. Adequate control of BP should be pursued as a way to avoid this severe complication of hypertension.

Cardiovascular diseases are the leading cause of deaths. Also, cardiovascular risk factors start the atherosclerotic process, which leads to cardiovascular diseases. Nowadays, periodontal disease can also be considered another cardiovascular risk factor. It involves inflammatory, immunological and humoral activities, which induce the production of proinflammatory cytokines and the destruction of the epithelium. This allows the entry of endotoxins and exotoxins in the bloodstream, which may contribute to atherogenesis and thromboembolic events. There is also direct invasion of the vessel wall by oral pathogens, triggering an inflammatory response that produces endothelial dysfunction. In hypertension, changes in microcirculation can cause ischemia in the periodontium, which favors periodontal disease. Moreover, endothelial dysfunction promotes the formation of atherosclerotic plaque and the development of lesions in target organs. Periodontitis has also been associated with insulin resistance and a higher risk for the metabolic syndrome, which is characterized by oxidative stress. This seems to act as a common link to explain the relationship between each component of the metabolic syndrome (including hypertension) and periodontitis. This article will discuss clinical and experimental evidence, as well as possible pathophysiologic mechanisms and links involved in the relationship among periodontal disease, hypertension and cardiovascular disease.

This national and representative registry identified important gaps in the incorporation of therapies with proven benefit, offering a realistic outlook of patients at high cardiovascular risk.

The acute application of ganglion TENS attenuated arterial stiffness in younger adults as well as hemodynamic measures in the middle-aged group. This method could emerge as effective therapy for the management of arterial blood pressure.
