(Epi)genetic factors in vascular disease

Abstract

This thesis examines the impact of genetic and epigenetic factors on several aspects of vascular disease. Part 1 addresses the influence of genetic variation in genes involved in the different processes that lead to the occurrence of adverse events after percutaneous coronary intervention, mainly restenosis after bare metal stent placement, but also late acquired stent malapposition after implantation of a drug-eluting stent. Part 2 discusses the role of a relatively new area of research, which we refer to as 'epigenetic epidemiology', in restenosis and other aspects of coronary heart disease. In this part we show that polymorphisms in genes encoding lysine acetyltransferases, which are able to modify chromatin structure to allow gene transcription, can influence restenosis and mortality from coronary heart disease in several large prospective follow-up studies.
