Abstract

Acute Coronary Syndromes (ACS) are characterized as a set of clinical symptoms compatible with acute myocardial ischemia and were responsible only in the year 2009 by more than 208,000 hospitalizations in the unified health system (SUS). The mechanisms that involve the occurrence of an event of ACS began with the formation and subsequent disruption of an atheromatous plaque and are related to intravascular thrombus formation, and in both cases partial or total artery occlusion are responsible for the myocardial ischemia. Because it is an inheritable and multifactorial disease, genetic association studies are important tools to define molecular markers for event prediction and prognosis in ACS. Therefore, the objective of this project is to validate 63 candidate polymorphic markers described in recently published GWAS as associated with CAD or cardiovascular risk factors and correlate them with the occurrence of cardiovascular events incidence in a one-year follow-up period. In addition, we will evaluate the expression of genes validated in two stages: at the time of first event and 30 days later, during treatment. We will study subjects of both sexes, regardless of age, with a confirmed diagnosis of ACS in the Emergency Room of the University of São Paulo's Hospital. For this, will use multiplex RT-PCR for genotyping, and RNA extraction with TRIzol ®, reverse transcription and quantitative real time PCR (qRT-PCR) to evaluate the expression of candidate genes in the two periods the study.
