- Patients with type 1 diabetes, secondary diabetes or acute metabolic diabetic complications will be excluded.
- Subjects will be excluded if they have cardiovascular disease (coronary heart disease, cerebrovascular disease or peripheral arterial disease) or if they are taking other medications known to affect lipoprotein metabolism (e.g. steroids, beta blockers, thiazide diuretics, lipid lowering agents: (statins, fibrates, ezetimibe, niacin), significant alcohol intake etc.).
