OBJECTIVE: To evaluated the clinical diagnostic, efficiency for basic death causes in patients dying of circulatory disease and de relative frequency of those diseases. METHODS: Analysis of medical record data of 82 patients, ages from 16 to 84 years old (68 over 40 years old), whose died of circulatory disease and had undergone necropsy in the period from 1988 to 1993 years in the University Hospital of Medicine Faculty of Botucatu-UNESP, Br. RESULTS: The functional class of patients were III or IV, in 78%, and 81.7% needed urgent hospitalization. By the clinical judgment the death were by ischemic heart disease in 32 (21 acute myocardial infarction), Chagas'disease in 12, valvopathy in 11, cardiomyopathy in 7, heart failure with no specification of cardiopathy in 11 and other causes in 9. At the necropsy the death cause was ischemic heart disease in 34 patients, valvopathy in 10, Chagas'disease in 10, cardiomyopathy in 5, and heart failure with no specification of cardiopathy in 2.The concordance taxes were in thhe same order: 94,6%, 90,0%, 83.3%, 71.4% and 28.5%. CONCLUSION: There was a great efficiency of clinical diagnosis for death cause in a general university hospital. The ischemic heart disease were the main causes of death.

INTRODUCTION. Cardiovascular diseases (CVD) are the main cause of death in Brazil.OBJECTIVE. To evaluate the frequency of CVD risk factors In a population attending a health education community event.METHODS. Retrospective study that included 428 completed forms with clinical and demographic information of volunteers attending a public event, in May, 2006. Data were expressed by means and standard deviation or proportions and compared by Student's t test or Chi-square test. Associations between Arterial Hypertension (AH), Diabetes Mellitus (DM) and clinical variables were analyzed by multinomial logistic regression. Significance level was p<0.05.RESULTS. Mean age was 57 +/- 14years, and women represented 58% of the total population. The main cardiovascular risk factors were AH (39.5%), DM (15.4%) and dyslipidemia (25.89%). The frequency of unawareness about these risk factors was respectively 8.4%, 17.5% and 33.1%.. Family history of CVD was reported by 41% while only 67% reported having any information about DM or dyslipidemia. Among obese individuals (IMC >= 30 Kg/m2, 27.3% of the population), systolic blood pressure (133 +/- 16mmHg), diastolic blood pressure (84 +/- 11.5mmHg) and casual glycemia (124 +/- 52.5mg/dl) were higher when compared to non-obese (p<0.05). There was a significant association between obesity and dyslipidemia (p=0.04). Age and IMC were independently associated with AH and DM.CONCLUSION. The high frequency of modifiable cardiovascular risk factors in this population suggests the need for educational programs to promote primary prevention, mainly for the elderly and overweight.

OBJECTIVE: To detect factors associated with cardiovascular mortality in the elderly of Botucatu. METHODS: We evaluated 29 variables of interest in a cohort of patients aged ³60 using data from a survey conducted between 1983/84. The elderly cohort was analyzed in 1992 to detect the occurrence of cardiovascular deaths. Survival analysis was performed using the Kaplan-Meier method, the log-rank test, and Cox regression analysis. Three models were adapted for each group of variables, and a final model was chosen from those variables selected from each group. RESULTS: We identified predictor for cardiovascular death according to age for elderly males not supporting the family, not possessing a vehicle, and previous cardiovascular disease. In elderly females, the predictor variables were previous cardiovascular disease and diabetes mellitus. CONCLUSION: Socioeconomic indicators (family heading and vehicle ownerrship) may be added to well stabilished medical factors (diabete mellitus and hypertension to select target groups for programs intended to reduce deaths due to cardiovascular diseases in elderly people.

Context: Presence of endothelial nitric oxide synthase (eNOS) gene polymorphism has been associated with cardiovascular disease (CVD) whereas exercise training (EX) promotes beneficial effects on CVD which is related to increased nitric oxide levels (NO). Objective: To evaluate if women with eNOS gene polymorphism at position-G894T would be less responsive to EX than those who did not carry T allele. Methods: Women were trained 3 days/week, 40 minutes session during 6 months. Cardio-biochemical parameters and genetic analysis were performed in a double-blind fashion. Results: Plasma NOx - levels were similar in both groups at baseline (GG genotype: 18.44±3.28 μM) and (GT + TT genotype: 17.19±2.43 μM) and after EX (GG: 29.20±4.33 and GT+TT: 27.38±3.12 μM). A decrease in blood pressure was also observed in both groups. Discussion and conclusion: The presence of eNOS polymorphism does not affect the beneficial effects of EX in women. © 2011 Informa UK, Ltd.

O Óxido Nítrico (ON) é gerado por uma família de isoenzimas, através da catálise enzimática do aminoácido essencial L-arginina, que resulta na formação de L-citrulina e ON. O on está envolvido em muitos processos fisiológicos dos mamíferos, que incluem a neurotransmissão, controle da pressão sangüínea, inflamação, reações imunológicas e nos mecanismos de defesa contra microorganisnos e tumores. O descontrole na síntese de on está implicado na patogênese de doenças cardiovasculares, autoimunidade, rejeição de transplantes, doenças degenerativas, na sépsis, na genotoxicidade e no surgimento de neoplasias. O on também foi incriminado como agente de iniciação da carcinogênese, que, associado a outros fatores, poderia levar ao descontrole da citoestase e da diferenciação celular. A diversidade de efeitos do on parece estar relacionada às concentrações de on gerados, à sensibilidade individual das células e à duração do fenômeno.

A obesidade é uma das doenças nutricionais mais frequentemente observada em cães e pode provocar sérios problemas de saúde, como os distúrbios cardiovasculares. Realizou-se este estudo visando avaliar algumas das possíveis alterações estruturais e funcionais cardíacas decorrentes da correção da obesidade canina. Para isso foram utilizados 18 cães obesos divididos pelo peso corporal em Grupo I (até 15kg), Grupo II (entre 15,1 e 30 kg) e Grupo III (acima de 30 kg). Os animais foram submetidos à restrição calórica de forma a perderem 15% do peso vivo. Foram realizados os exames ecocardiográfico em modo-M, eletrocardiográfico e mensuração da pressão arterial dos animais antes do início do tratamento da obesidade e após atingirem o peso meta. Os resultados revelaram que após a redução de peso ocorreram diminuições significativas da espessura da parede livre do ventrículo esquerdo durante a sístole e diástole no Grupo III, diminuição da pressão arterial sistólica no Grupo III e também da pressão arterial média no Grupo II. Assim, concluiu-se que a perda de peso pode reverter as alterações estruturais cardíacas, como a hipertrofia excêntrica do ventrículo esquerdo em cães obesos acima de 30 kg, como também reduzir a pressão arterial sistêmica em cães obesos submetidos à restrição calórica mediante administração de dieta hipocalórica.
