Role of blood pressure in the progression of microalbuminuria in elderly Japanese type 2 diabetic patients: a 7-year follow-up study.
This 7-year retrospective longitudinal study was carried out in order to clarify the clinical features of elderly type 2 diabetic patients with microalbuminuria. Elderly Japanese type 2 diabetic patients (n = 22; age 50 - 73 years) with microalbuminuria were studied retrospectively. Patients whose urinary albumin excretion rate (UAER) decreased 7 years were considered 'nonprogressors' (n = 8) whereas those whose UAER increased were considered 'progressors' (n = 14). The mean 7-year level of glycosylated haemoglobin (HbA1c) did not differ significantly between non-progressors and progressors but the mean 7-year blood pressure (BP) of progressors (101 +/- 8 mmHg) was significantly higher than that of non-progressors (92 +/- 7 mmHg). In progressors who received no anti-hypertensive drugs, systolic BP was above the BP goal of 130/85 mmHg but mean BP and diastolic BP were below this goal. The results are consistent with the view that hypertension affects the progression of microalbuminuria; raised systolic BP may be a factor in this progression in elderly type 2 diabetic patients.
