Serum leptin level as a cardiovascular risk factor in type 2 diabetic patients

Abstract

Type 2 diabetes mellitus ( T2DM ) is a metabolic disease that is associated with an increased risk for atherosclerosis. Leptin is a hormone – like cytokine that is derived mainly from adipose tissue and has multiple functions. Recently, many vascular and atherogenic effects for leptin have been demonstrated. The aim was to study serum leptin level and its relationship with some cardiovascular risk factors in T2DM patients. Forty diabetic males with ischemic heart disease (IHD group), aged ≥ 40 years old, were compared with 40 diabetic males of similar ages who had no clinical history of IHD (DM group). Each main study group was divided into two subgroups according to the presence or absence of metabolic syndrome. The IHD group was also subdivided according to their clinical endpoints into stable angina pectoris (angina group), significant coronary artery disease on angiography (angiography group ) and myocardial infarction (MI group ).In addition to anthropometric measurements; serum lipid profile, thiobarbituric acid -reactive substances (TBARS) and leptin levels as well as plasma fibrinogen level were quantified .
