Abstract: background: from a mechanistic standpoint, obstructive sleep apnea (osa) may further disturb cardiovascular homeostasis in the setting of acute coronary syndrome (acs). objective: we sought to investigate if a standardized clinical diagnosis of osa, in acute coronary syndrome patients, predicts the risk of cardiovascular events during hospitalization. methods: in a prospective cohort study, a group of 200 patients diagnosed with acs between september 2005 and november 2007 were stratified by the berlin questionnaire (bq) regarding the risk for osa (high or low risk). we tested if the subgroup of high risk for osa was prone to a higher frequency of cardiovascular events. the primary endpoint evaluated was a composite outcome of cardiovascular death, recurrent cardiac ischemic events, acute pulmonary edema and stroke during hospitalization. results: ninety four (47%) patients assessed by the bq were likely to have osa. high risk for osa was associated with a non-significant higher mortality (4.25% vs 0.94%; p=0.189), but a significant higher incidence of composite cardiovascular events (18.08% vs 6.6%; p=0.016). in the logistic regression model, multivariate predictors of composite cardiovascular events were age (or= 1.048; 95% ci 1.008 to 1.090; p=0.019), left ventricular ejection fraction (or= 0.954; 95% ci 0.920 to 0.989; p=0.010), and higher risk for osa (or= 3.657; 95% ci 1.216 to 10.996; p=0.021). conclusion: the use of a simple and validated questionnaire (bq) to identify patients with higher risk for osa may help in the prediction of cardiovascular outcome during hospitalization. moreover, our data suggests that osa is very common in patients with acs.

Abstract: 193 diabetic patients, 97 males, 59.8 ± 9.3 yrs (mean ± SD) were submitted to EE between 2001 and 2006 and followed from 7 to 65 months with median of 29 months by phone calls and personal interviews with patients and their primary physician, and reviewing medical records and death certificates. The end points were cardiac events, defined as non-fatal myocardial infarction, late myocardial revascularization and cardiac death. Sudden death without another explanation was considered cardiac death. Survival free of end points was estimated by the Kaplan-Meier method.Twenty-six cardiac events were registered in 24 individuals during the follow-up. The rates of cardiac events were 20.6 and 7% in patients with positive and negative EE, respectively (p < 0.001). Predictors of cardiac events included sedentary lifestyle, with RR of 2.57 95%CI [1.09 to 6.02] (P = 0.03) and positive EE, with RR 3.63, 95%CI [1.44 to 9.16] (P = 0.01). Patients with positive EE presented higher rates of cardiac events at 12 months (6.8% vs. 2.2%), p = 0.004.EE is a useful method to predict cardiac events in diabetic patients with suspected or known CAD.Diabetes mellitus (DM) is a major risk factor for cardiovascular morbidity and mortality [1-5]. Accordingly, both the American Heart Association and American College of Cardiology define DM as an equivalent to previous coronary artery disease (CAD) for cardiovascular risk [5]. When associated with other cardiovascular risk factors, DM increases the rate of macrovascular complications.The mean annual mortality rate of asymptomatic patients with multiple cardiovascular risk factors is 3% [6]. In diabetic patients, chronic CAD frequently presents reduced subjective symptoms, unless ventricular dysfunction is present [7]. Recognition of subclinical ischemic disease in diabetic patients and stratification of risk are important to select therapeutic interventions and to reduce the complications of cardiac events [2,7-10].Exercise echocardiography (EE) i

Abstract: growth hormone (gh), the main regulator for post-natal growth, has important metabolic actions on different tissues, similar or opposite to insulin like growth factor i (igf-i), mainly produced by the liver after the binding of gh to its receptor. experiments with animal models indicate an important role of gh on insulin resistance although the igf-i role is not yet completely established. in humans, gh promotes an increase on lypolisis and lipid oxidation, while igf-i leads to an increase on lipid oxidation only in a chronic way. while growth actions are time-limited, metabolic and cardiovascular actions of the gh/igf-i axis are throughout life. gh anabolic effects have been used on chronic and hypercatabolic conditions, although investigations on the clinical outcomes are still scarce. in this paper, we intend to review gh metabolic actions experienced by animal models, studies with normal humans and gh deficient individuals, individuals with diabetes mellitus type 1 and metabolic syndrome individuals, hypercatabolic states and the relationship between gh and adipokines, endothelial disfunction and atherogenesis

Abstract: background: more recently, the association of different risk factors has been described as the metabolic syndrome. different definitions are being used for the same syndrome. regardless of the name or classification, it has been well established that a cardiovascular cluster including overweight/obesity, increased blood pressure, and lipid and glucose abnormalities are associated with an increased risk of atherosclerosis in adults. objective: the aim of this study was to correlate body mass index percentiles with blood pressure, insulin resistance index, and lipid profiles in children and adolescents, which characterize a proatherosclerotic profile. methods: cardiovascular risk factor clusters were evaluated in 118 children and adolescents divided according to body mass index percentile (bmip) quartiles: q1 (n=23) with bmip <50%, q2 (n=30) with bmip between 50 and 85%, q3 (n=31) with bmip between 85 and 93%, and q4 (n=34) with the bmip > 93%. statistically significant differences were not observed for age (f=2.1; p=0.10); sex (chi-square test=3.0; p=0.38), and ethnicity (chi-square test=4.7; p=0.20) between different quartiles. results: a statistically significant difference was observed for systolic bp (f=15.4; p<0.0001), diastolic bp (f=9.5; p<0.0001), glycemia (f=9.6; p<0.0001), insulin (f=12.9; p<0.0001), homair (f=30.8; p<0.0001), and triglyceride levels (f=2.7; p=0.05) between the different quartiles. conclusion: excess weight evaluated by bmip was associated with increased blood pressure, triglycerides, homair index, and low hdl-cholesterol, a proatherosclerotic profile in children and adolescents.
