The role of lipoprotein(a) in the vascular complications of diabetes mellitus

Abstract

Abstract. Lipoprotein(a) has been identified as an independent risk factor for atherosclerotic vascular disease in non‐diabetic populations. Because of its potential role in the pathogenesis of both microvascular and macrovascular complications in diabetes, there have recently been many reports on lipoprotein(a) in diabetic populations. Some studies indicate an association between elevated lipoprotein(a) and macro‐vascular disease in non‐insulin‐dependent diabetes mellitus (NIDDM), but this link has not been found with insulin‐dependent diabetes mellitus (IDDM). In IDDM, elevated lipoprotein(a) has been found in groups with diabetic nephropathy and retinopathy, raising the possibility that it plays a causative role. The relationship between glycaemic control and the lipoprotein(a) level has not been fully resolved. Most studies have not found any connection in NIDDM, but some found higher lipoprotein(a) levels in hyper‐glycaemic IDDM patients. Potentially, lipoprotein(a) is an important factor linking the microvascular and macrovascular complications of diabetes. 1995 Blackwell Publishing Ltd
