Increase in blood pressure and its circadian alterations in Type 1 diabetes are usually associated with diabetic nephropathy. To evaluate if diabetes itself could be responsible for the observed increase in blood pressure levels, we studied a group of 17 normotensive, normoalbuminuric Type 1 diabetic patients with a disease duration more than 15 years, with no clinical evidence of autonomic neuropathy or ischaemic heart disease, and without any known determinant of hypertension, and a control group of 17 normal subjects, normotensive, each matched for sex, age, BMI, albumin excretion rate, and clinical blood pressure to a diabetic subject. In both groups an ambulatory blood pressure monitoring was performed through an oscillometric recorder. The mean systolic and diastolic ambulatory blood pressure values were significantly higher in diabetic patients ( p <0.001) in the 24‐h analysis and during waking and sleeping periods. The night/day ratio of systolic and diastolic blood pressure were not significantly different in patients and controls, as well as heart rate values and heart rate variability. We conclude that mechanism(s) inherent to the diabetic condition other than diabetic nephropathy or autonomic neuropathy could be responsible for blood pressure evaluation in normotensive Type 1 diabetes with normoalbuminuria.
