Evaluation of orthostatic hypotension frequency and associated factors in type 2 diabetics
Abstract
UNLABELLED: Orthostatic hypotension is a major criterion for diabetic autonomic cardiac neuropathy. It increases overall and cardiovascular mortality.
PURPOSE: The aim of our study was to evaluate the orthostatic hypotension frequency in type 2 diabetics and to investigate the associated factors.
METHODS: This prospective cross-sectional study included adult patients with type 2 diabetes. Orthostatic hypotension was defined as a decrease in the systolic arterial pressure>20mm-Hg or a decrease in the diastolic arterial pressure>10mm-Hg, after 3minutes of standing position. The arterial pressure was measured with a validated electronic device. Vascular risk factors and micro and macro-vascular complications were systematically investigated by the appropriate diagnostic means.
RESULTS: We evaluated 300 diabetic patients. Of these women represented 57%. The mean age was 58 years old. The average duration of diabetes was 8 years. The antidiabetic drugs were metformin (82%), sulfonylureas (36%) and insulin (40%). High blood pressure was present in 49% among whom 50% of patients received angiotensin II receptor blockers, 47% diuretics, 24% angiotensin converting enzyme inhibitors, 17% beta blockers, and 17% calcium channel blockers. Orthostatic hypotension has been identified in 26 patients (8.6%). In multivariate analysis, the associated factors with orthostatic hypotension were elevated systolic blood pressure and insulin treatment.
CONCLUSION: The frequency of orthostatic…
