Background: Pulse pressure (PP) is an independent predictor of cardiovascular disease microalbuminuria in non-diabetic people. Reduced circadian blood pressure (BP) variation has been identified as a risk factor for diabetic complications. In a sample of type 2 diabetic patients, we looked at the relationship between retinopathy, nephropathy, macrovascular disease, PP, and diurnal BP change. Method: We performed a 24-hour ambulatory blood pressure (AMBP) and fundoscopy on 100 type 2 diabetes patients, and urine albumin excretion was measured using the urinary albumin / creatinine ratio. It was determined whether or not macrovascular disease existed.
