OBJECTIVE: In IDDM, the development of microalbuminuria, which is associated with an elevation in blood pressure within the normal range, is a risk factor for future cardiovascular disease. Vascular stiffness might be one of the factors involved because it increases systolic blood pressure and the workload of the heart. RESEARCH DESIGN AND METHODS: We investigated carotid artery stiffness with a noninvasive ultrasound method in 24 microalbuminuric and 53 normoalbuminuric IDDM patients and in 54 healthy control subjects. RESULTS: The distensibility coefficient, a measure of intrinsic vascular wall elasticity, was decreased in microalbuminuric IDDM (21.6 x 10(-3)/kPa) as compared with normoalbuminuric IDDM (24.8 x 10(-3)/kPa) and control subjects (25.9 x 10(-3)/kPa; P = 0.02). This result was based on a higher blood pressure in microalbuminuric patients. After correction for the difference in blood pressure, the distensibility coefficients were similar in the three groups. In the two diabetic patient groups taken together, age, blood pressure, female sex, diabetes duration, and cigarette smoking were determinants of a decreased distensibility. CONCLUSIONS: Blood pressure is a major determinant of increased arterial stiffness in microalbuminuric IDDM patients. Increased arterial stiffness may contribute to the accelerated progression of complications if concomitant hypertension exists.
