Abstract

Diabetes mellitus is, as compared with the non-diabetic population, associated with a much higher mortality of ischaemic heart disease and other cardiovascular diseases. In this risk participates in a major way also diabetic dylipidaemia. The latter is characterized in particular by hypertriglyceridemia which reflects the increase of VLDL and IDL lipoproteins. Elevated and prolonged postprandial lipaemia participates in the development of qualitative lipoprotein changes. Highly athergenic "small dense LDL" are formed which are liable to an oxidative modification and are then in an unregulated manner taken up in the vascular wall. Reduction of HDL-cholesterol and a change in the different HDL sub-populations leads then to a deteriorated reverse cholesterol transport. Type 2 diabetes mellitus is associated with dyslipidaemia in the majority of patients even under conditions of satisfactory compensation of diabetes, in particular during the postprandial stage. On the other hand, in type 1 diabetes the lipid values usually become normal when the blood sugar level becomes normal, however qualitative changes of lipoproteins frequently persist. Increased glycation and oxidation of lipoproteins is a common sign of both types of diabete...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

CV Disorders & Type 2 Diabetes
