ABSTRACT

Objetivo - Avaliar a estrutura e função do ventrículo esquerdo (VE) e a rigidez arterial em portadores de diabetes mellitus tipo II. Métodos - Foram estudados 13 doentes diabéticos de ambos os sexox (55 "mais ou menos" 8 anos) sem outras doenças. A estrutura e funçäo do VE foram avaliadas por meio de ecodopplercardiografia associada à monitorizaçäo näo invasiva da pressäo arterial (PA). Os resultados foram comparados aos obtidos em grupo de indivíduos normais de mesma idade (n=12). Resultados - Näo houve diferenças entre os grupos quanto a PA diastólica, dimensöes das câmaras esquerdas e índices de funçäo sistólica e diastólica. Os pacientes diabéticos apresentaram índice de massa do VE (101 "mais ou menos" 10 vs 80 "mais ou menos" 14 g/m2; p "menor" 0,001) e índice de rigidez arterial sistêmica ( 0,86 "mais ou menos" 0,26 vs 0,69 "mais ou menos" 0,19 mmHg/mL; P "menor" 0,05) significantemente maiores que os controles. Conclusäo - O diabets mellitus está associado a aumento da rigidez arterial sistêmica e esse fator poderia contribuir para seus efeitos adversos sobre o VE.

ABSTRACT

PURPOSE: To evaluate the left ventricular structure and function and the arterial stiffness in type II diabetic patients. METHODS: Thirteen diabetic patients, men and women (age 55 +/- 8 years) were included in the study. None of the patients had any other clinical disorders. Doppler-echocardiography and non-invasive monitoring of arterial blood pressure were performed. All the results were compared to an age and sex matched control group (n = 12). RESULTS: There were no differences between the groups for diastolic blood pressure, dimensions of cardiac chambers and ventricular systolic and diastolic function indexes. Diabetic patients had increased left ventricular mass index (101 +/- 10 vs 80 +/- 14 g/m2; p < 0.001) and increased arterial stiffness (0.86 +/- 0.26 vs 0.69 +/- 0.19 mmHg/mL; p < 0.05), when compared to control group. CONCLUSION: Diabetes mellitus is associated to increased systemic arterial stiffness and this may contribute to the adverse effects of diabetes on left ventricular morphology.
