Genetic Mapping for Cardiac Risk Assessment

Study Overview
=================
Brief Summary
-----------------
The main objective of the GENOCOR project (Genetic mapping for cardiac risk assessment) is the setting up of a joint public/private laboratory (GENOCOR-LAB) dedicated to the development and testing of new cost-effective technologies exploiting the growing knowledge in the genomic correlates of cardiovascular diseases (CVD) and of their evolution; the data obtained by the GENOCOR-Lab should especially orient secondary prevention and specific treatment of ischemic heart diseases (IHD).

Detailed Description
-----------------
The Laboratory will be based in the premises of the CNR Institute of Clinical Physiology, a research institution operating as CVD Research Hospital System, with two Hospital Units (CNR Campus in Pisa and G. Pasquinucci Hospital in Massa). The project is based on the cooperation of a national private company (DiaSorin, endowed with promising proprietary technologies in the novel diagnostic biotechnologies) and three research units (at clinical and molecular biology level) two from the National Research Council (IFC-CNR, Pisa and ITB-CNR, Milano, both very active in advanced biological research) and one from the University Vita-Salute San Raffaele (UHSR, Milano, operating a top range hospital and center for advanced biological research): GENOCOR Lab becomes then the first product of the cooperation within the CNR MERIT Network (MEdical Reseach in ITaly) currently being set-up by CNR. The project is based on the availability of proprietary large scale databases of selected clinical populations that will be probed with the novel genomic and post-genomic technologies. High throughput SNPs technologies and post-genomic expression and proteomic analyses will be used to assess profiles of genetic variability identifying subjects with a distinct proneness to ischemic heart disease (IHD), hard cardiovascular events and unfavourable outcomes. Specific focusing will be made possible by the availability, within the proposed research network, of well established clinical data bases and biological sample collections, enabling the retrospective and prospective access to large and well characterised populations of patients with IHD. Cardiovascular phenotypes will include patients with acute coronary syndromes (unstable angina and acute myocardial infarction) and patients with chronic ischemic heart disease and prolonged follow-up; with this approach, it will be possible to cover both short-term and long-term evolution by detailed clinical, biohumoral and instrumental phenotyping at the time of acute events and with a systematic follow-up. This approach should allow to overcome the major limitations and unbalance of previous studies, either focussed to small well characterized populations in which few genetic variations have been explored, or extended to large populations with a wider gene variability approach but inadequate information on phenotype and evolution disease.
