Usefulness of home blood pressure measurement in the morning in type 1 diabetic patients.

Abstract

Recently, we reported that home blood pressure (BP) measurement in the morning has a stronger predictive power for micro- and macrovascular complications in type 2 diabetic patients than casual/clinic BP measurement (1). Here we report the results examined in the study of type 1 diabetic patients. We studied 53 type 1 diabetic patients who regularly visited our clinics. The number of female patients (36) was twice that of male patients (17). The subjects were aged 23–81 years (mean 54 ± 17) and had a diabetes duration of 2–47 years (mean 17 ± 10). Their mean BMI was 22 ± 3 kg/m2, HbA1c 7.0 ± 0.9%, triglycerides 94 ± 44 mg/dl, total cholesterol 201 ± 32 mg/dl, LDL 107 ± 25 mg/dl, and HDL 75 ± 18 mg/dl. Of 53 patients, 38 (72%) were treated by multiple daily insulin injections and the remaining (28%) received subcutaneous continuous insulin infusion for diabetes. Twenty-two patients (42%) were treated with antihypertensive drugs at the beginning of the study. The study design and analysis are the same as previously reported (1). BP was measured at the clinic during the day and at home after waking. Clinic hypertension and morning hypertension were defined as systolic BP (SBP) 130 mmHg and/or diastolic BP (DBP) 85 mmHg, whereas clinic normotension and morning normotension were SBP …
