Exercise-induced hypertension in normotensive patients with NIDDM.
The aim of this study was to determine whether blood pressure during mild to moderate exercise is abnormal in patients with non-insulin-dependent diabetes mellitus (NIDDM). The study group consisted of 11 patients with NIDDM and 11 nondiabetic subjects of comparable age and body mass index. All subjects were sedentary and basally normotensive. Bicycle ergometry was used to assess the effect of exercise on blood pressure at a steady state of 70-75 W, with a target duration of 20 min. Blood pressure was measured basally and every 5 min. Greater exercise-induced systolic blood pressure (mean max 208.0 +/- 6.0 vs. 177.0 +/- 3.0 mmHg) occurred in the NIDDM group (P less than 0.001). Neither pulse rate nor diastolic blood pressure differed between the groups before or during exercise. Return to basal pulse and blood pressure was similar. Mild to moderate exercise induces greater systolic blood pressure in sedentary patients with NIDDM. Because exercise is recommended as one therapeutic modality, intraexercise blood pressure should be considered in assessing the safety of this form of treatment.
