Management Of Lipids in Patients with Diabetes Mellitus Type 2
13
Clear Instructions to Our Patients
14
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
15
Suggested Risk Factor Target Levels RISK FACTORGOAL Blood pressure130/80 mm Hg HbA1c<7.5% BMI<25kg/m 2 Waist circumference males<98 cm females<88 cm Urinary albumin excretion<30 mg/day
16
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
