Lack of management of cardiovascular risk factors in type 2 diabetic patients

Effective management of diabetic patients includes comprehensive control for not only blood sugar, but also other cardiovascular risk factors. We assessed whether haemoglobin A1c (A1C) concentrations, blood pressure, low density lipoprotein (LDL) cholesterol levels and microalbuminuria were regularly measured in 281 patients with type 2 diabetes who received care for over 1 year in the Department of Family Medicine located in an urban area of Korea. Subsequently, in patients with A1C > 7%; blood pressure >130/80 mmHg; LDL cholesterol levels >100 mg/dl; or microalbuminuria, we evaluated the status of management for those cardiovascular risk factors. Physicians were most likely to measure A1C levels (98.6%), but less likely to measure microalbuminuria (56.2%), LDL cholesterol (73.7%), or blood pressure (74.4%). Patients whose A1C levels were above the goal (78.2%) were likely to receive optimal therapy. In contrast, only 21.1% of patients with uncontrolled blood pressure and 5.3% of patients with LDL cholesterol levels above the target range received optimal management. Of the 36 patients with microalbuminuria or overt proteinuria, 66.7% took angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Measurement of parameters indicating cardiovascular risk factors in type 2 diabetic patients was not optimal, particularly regular measurements for microalbuminuria and for controlling LDL-cholesterol and blood pressure. These findings indicate a need for greater education of comprehensive cardiovascular management in type 2 diabetic patients and their physicians.
