Management Of Lipids in Patients with Diabetes Mellitus Type 2
Risk Factor Management General Rules • Risk factor assessment • Setting goals for therapy • Primary prevention • Secondary prevention • Specific modalities of therapy based on impact and practicality • Lipid management • Asperin use • Blood pressure control • Smoking cessation • Glycemic control • Weight management
Suggested Risk FactorTarget Levels RISK FACTOR GOAL Blood pressure 130/80 mm Hg HbA1c <7.5% BMI <25kg/m2 Waist circumference males <98 cm females <88 cm Urinary albumin excretion <30 mg/day
Lipid Management Glycaemic Control • Glucose lowering in untreated diabetics will improve the lipidprofile • Better glycaemic control, independent of mode of therapy, further improves the lipidprofile • Unfortunately target lipid levels are not achieved with good glycaemic control in most patients
