We evaluated the relationship of EFT with carotid intima-media thickness (CIMT) and ankle-brachial index (ABI), in patients with metabolic syndrome.

Evaluation of risk factors in the development of type 2 diabetes in a Mexican population.

Type 2 diabetes (T2D), which causes many adverse effects such as endothelial dysfunction and cardiovascular disease, affects approximately 425 million people worldwide. However, about half have not yet been diagnosed. For what is recommended the use of screening tools to identify individuals at risk for T2D or in the early stages of the disease in order to impement preventive strategies or early treatment.

Triglycerides and waist to height ratio are more accurate than visceral adiposity and body adiposity index to predict impaired fasting glucose.

Aims: To evaluate the clinical accuracy of novel indices visceral adiposity index (VAI) and body adiposity index (BAI) to identify patients with impaired fasting glucose (IFG) and compare with its individual components and other obesity indicators.

Methods: A cross-sectional study was conducted in Mexican population. Body mass index (BMI), waist circumference, hip circumference, triglycerides (TG), High density lipoprotein cholesterol (HDL-C), VAI, BAI, waist to hip ratio (WHR) and waist to height ratio (WHtR) were determined.

Prehypertension is associated with peripheral arterial disease and low ankle-brachial index.

Unlabelled: Patients with prehypertension suffer endothelial dysfunction and are at increased cardiovascular risk. Ankle-brachial index (ABI) constitutes an efficient tool for diagnosing peripheral arterial disease; but also an ABI<0.9 is an independent and positive predictor of endothelial dysfunction and is associated with increased cardiovascular risk and mortality.

Combination therapy in the treatment of hypertension.

Hypertension is a major preventable risk factor for atherosclerosis and ischemic heart disease. Although modern and effective antihypertensive drugs are available, most patients remain with a suboptimal blood pressure control. Most hypertensive patients will need a combination of antihypertensive agents to achieve the therapeutic goals - recent guidelines recommend initiating treatment with two drugs in those patients with a systolic blood pressure >20 mmHg and/or a diastolic blood pressure >10 mmHg above the goals, and in those patients with high cardiovascular risk.

[Effect of the components of the metabolic syndrome on pulmonary function. The unexpected role of high-density lipoprotein cholesterol].

Background: Metabolic syndrome is a condition that predisposes to cardiovascular disease and diabetes mellitus. In addition, it can have effects over neoplastic pathologies, liver and pulmonary function. Our objective is to analyze the effect of the metabolic syndrome and its components on pulmonary function.

Echocardiographic measurements of epicardial adipose tissue and comparative ability to predict adverse cardiovascular outcomes in patients with coronary artery disease.

Outcomes of 107 patients (86 males, 21 females, mean age 63.6 years old) submitted to diagnostic echocardiography and coronary angiography were prospectively analyzed.

Correlation between epicardial fat thickness and biochemical markers of metabolic risk.

Introduction And Objective: Epicardial fat has been associated with increased cardiovascular risk and the development of atherosclerosis. Transthoracic echocardiography provides a reliable measurement of epicardial fat thickness (EFT). The aim of this study is to evaluate the relationship between EFT and biochemical parameters of metabolic risk.

Serum uric acid levels are associated with homeostasis model assessment in obese nondiabetic patients: HOMA and uric acid.

Background: Hyperuricemia leads to insulin resistance, whereas insulin resistance decreases renal excretion of uric acid. The aim of this study was to evaluate whether there is a correlation between serum uric acid levels with homeostatic model assessment (HOMA) 1 in nondiabetic patients.

Methods: We evaluated 88 nondiabetic patients, in whom uric acid levels were measured, in all of them HOMA of β-cell function (HOMA 1B) and HOMA of insulin resistance (HOMA 1IR) scores were performed.

Effect of losartan combined with amlodipine or with a thiazide on uric acid levels in hypertensive patients.

Unlabelled: Hyperuricemia leads to endothelial dysfunction and insulin resistance, and has been associated with diseases such as hypertension. Antihypertensive drugs modify serum uric acid levels, however, few data are available about their combinations on uricemia. In this study we evaluate the effect of two combinations of losartan, with amlodipine or with hydrochlorothiazide, on serum uric acid levels in hypertensive patients.

Circulating Adipokine Levels in Non-diabetic Subjects with High Normal Blood Pressure.

Objective: This study aimed to evaluate the levels of the adipokines, resistin and adiponectin in normotensive and high normal blood pressure patients.

Methods: Circulating levels of the adipokines, resistin and adiponectin were measured by enzyme-linked immunosorbent assay (ELISA; R'D Systems, Minneapolis) in 20 high normal blood pressure patients and in 20 age-matched normotensive non-diabetic subjects. Statistical analysis was performed with analysis of variance (ANOVA).

Circulating Levels of Uric Acid and Risk for Metabolic Syndrome.

Unlabelled: Hyperuricemia leads to insulin resistance, whereas insulin resistance decreases renal excretion of uric acid, both mechanisms link elevated serum uric acid with metabolic syndrome. The aim of this study is to evaluate the probability for the development of metabolic syndrome in low-income young adults with hyperuricaemia.

Methods: We evaluated 103 patients less than 40 years of age, from a low-income population, and without history of cardiovascular disease, in all of them the presence of metabolic syndrome was assessed in accordance with the International Diabetes Federation criteria.

Recommendations for the treatment of hypertension in elderly people.

High blood pressure is a major cardiovascular risk factor. The prevalence of hypertension increases with aging. As a consequence of changes in arterial wall that leads to arterial stiffness, the majority of elderly patients suffer isolated systolic hypertension.

Lifestyle changes and surgical treatment for hypertension in the elderly.

Hypertension is a major cardiovascular risk factor that increases morbidity and mortality in the elderly because, numerous factors contribute to development and progression of hypertension in elderly patients, including excessive salt intakes, obesity, physical inactivity and stress. Hypertension treatment usually results in a combination of both, pharmacologic and non-pharmacologic measures. These latter are an essential part of treatment and cannot be replaced by the medication.

Efficacy of Change to New P2Y12 Receptor Antagonists in Patients High on Treatment Platelet Reactivity Undergoing Percutaneous Coronary Intervention.

Selective intensification of platelet inhibition may improve high on treatment platelet reactivity (HPR). We evaluated the efficacy of dual-antiplatelet therapy, including clopidogrel (CPG), compared to new P2Y12-receptor antagonists in patients with HPR undergoing percutaneous coronary intervention, regarding the outcome of composite major adverse cardiac events (MACEs, including death, acute coronary syndrome [ACS], and stent restenosis). The presence of HPR (71 of 181 patients) almost doubled the risk of MACEs.

[Prevalence of abnormal glucose tolerance in hypertensive patients].

Background: Type 2 diabetes mellitus is commonly associated with hypertension; the standard oral glucose load is an independent risk factor for cardiovascular disease. The aim of this research is to show the prevalence of abnormal glucose tolerance in hypertensive patients with normal fasting glucose.

Methods: We enrolled 65 hypertensive non diabetic patients with fasting glucose < 100 mg/dL.

Diabetic nephropathy and inflammation.

Diabetic nephropathy (DN) is the leading cause of end-stage renal failure worldwide. Besides, diabetic nephropathy is associated with cardiovascular disease, and increases mortality of diabetic patients. Several factors are involved in the pathophysiology of DN, including metabolic and hemodynamic alterations, oxidative stress, and activation of the renin-angiotensin system.

Correlation between biopterin levels and intimal-media thickness in type-2 diabetic hypertensive patients.
