ABSTRACT

Em portadores de diabetes mellitus (DM), o diagnóstico de doença arterial coronariana (DAC) é comumente tardio devido à presença de isquemia miocárdica silenciosa (IMS). O objetivo do presente estudo foi avaliar os fatores de risco cardiovascular e a freqüência de IMS, em portadores de DM. Foram estudados 125 indivíduos: 42 portadores de DM e de hipertensão arterial (HA) (grupo 1), 22 portadores de DM, sem HA (grupo 2); 32 portadores de HA, sem DM (grupo 3) e 29 indivíduos sem DM e HA (grupo 4). Foram obtidos dados sobre duração do DM, história familiar de coronariopatia, história de tabagismo, dosagens de colesterol total e HDL, triglicérides, creatinina plasmática e relação albumina-creatinina, em amostra isolada de urina. Todos os indivíduos foram submetidos a avaliação cardiológica e teste ergométrico (TE). O índice de massa corporal foi semelhante entre os grupos. Os valores de colesterol total foram 207±38mg/dL, 231±35mg/dL, 214±47mg/dL, 216±51mg/dL (ns); HDLcolesterol: 47±13mg/dL, 42±7mg/dL, 41±8mg/dL, 48±15mg/dL (ns), LDL colesterol: 123±36mg/dL, 165±70mg/dL, 152±62mg/dL, 139±48mg/dL (p<0,05, grupos 1 e 4 vs grupos 2 e 3), triglicérides: 196±175mg/dL, 164±51mg/dL, 176±108mg/dL, 158±68mg/dL (ns), nos grupos 1, 2, 3 e 4, respectivamente. O TE foi positivo para isquemia miocárdica em 19 (15,2%) indivíduos, sendo 14 (73,7%) do grupo 1. A elevada freqüência de IMS observada em portadores de DM e HA sugere que a realização do TE seja incorporada na avaliação de rotina dessa população de risco.


Coronary artery disease (CAD) in patients with diabetes mellitus (DM) is diagnosed late in part due to silent myocardial ischemia (SMI). The aim of this study were to evaluate cardiovascular risk factors and the frequency of SMI in patients with DM. One-hundred and twenty-five individuals were studied: 42 diabetic hypertensive patients (group 1), 22 diabetic normotensive patients (group 2); 32 non-diabetic hypertensive patients (group 3) and 29 non-diabetic normotensive individuals (group 4). Data on DM duration, family history for coronary disease, cigarette smoking, total and HDL cholesterol, triglycerides, creatinine and urinary albumin-urinary creatinine ratio were obtained. Cardiovascular evaluation and exercise stress test (EST) were performed for all subjects. Mean body massindex was similar in the 4 groups. Values of total cholesterol were 207±38 mg/dL, 231±35 mg/dL, 214±47 mg/dL, 216±51 mg/dL (ns); HDL-cholesterol: 47±13 mg/dL, 42±7 mg/ dL, 41±8 mg/dL, 48±15 mg/dL (ns), LDL cholesterol: 123±36 mg/dL, 165±70 mg/dL, 152±62 mg/dL, 139±48 mg/dL (p<0,05, group 1 and 4 vs groups 2 and 3), triglycerides: 196±175 mg/dL, 164±51 mg/dL, 176±108 mg/dL, 158±68 mg/dL (ns), in groups 1, 2, 3and 4, respectively. Nineteen subjects (15,2%) had a positive EST for myocardial ischemia. Among them, 14 (73,7%) were from group 1. The high frequency of SMI observed in diabetic hypertensive patients suggests that EST should be considered as a routine test for evaluation of this high-risk population.

ABSTRACT

A hipertensão arterial sistémica (HA) é síndrome que atinge 15% da população adulta mundial e se acompanha de altos índices de morbidade e mortalidade. Nos últimos anos tem sido crescente o interesse das autoridades de saúde no diagnóstico e esclarecimento da população quanto à HA. Neste sentido, têm sido realizadas campanhas de esclarecimento sobre a HA em todo o país. O presente levantamento é parte da Campanha Nacional de Prevenção e Combate à Hipertensão (CNPCH), pela primeira vez realizada em Juiz de Fora, quando foram atendidos 7.957 cidadãos, o que corresponde a 3 % da população adulta dessa cidade. À análise dos resultados observou-se que grande parte da população pesquisada desconhecia o diagnóstico (42,5%) ou não se encontrava adequadamente tratada (75,2%). Observou-se ainda que os homens com idade superior a 40 anos eram mais propensos à hipertensão e que indivíduos da raça negra apresentavam maior prevalência de HA.


Hypertension is a syndrome with a prevalence of 15% in adults and it is associated with high rates of morbidity and mortality. In recent years, Health Care authorities have focused their attention on the diagnosis of hypertension and especially regarding to educational programs. Accordingly, several campaigns have been launched with the objective of detecting and preventing its consequences. Our data were obtained from the "National Campaign for Detection and Treatment of Hypertension" conducted nationwide and also in Juiz de Fora. Seven thousand, six hundred and fifty two adult subjects (3% of the population of Juiz de Fora) had their blood pressure measured. It was found that 42.5% of the hypertensives were not aware of their high of blood pressure levels and, among those known to be hypertensive, blood pressure was not adequately treated in 74,8%. A higher prevalence of hypertension among men in their forties and in the black population was observed.
