Brief summary: This study research the similarity of coronary artery lesions according to HLA tissue compatibility in fisrt degree relatives of the patients who just admitted clinic as Acute coronary syndrome and underwent angiyography before .

Detailed description: Coronary artery disease (CAD), which is mainly caused by atherosclerosis, is the most prevalent illness and the leading cause of death worldwide. Increasing evidence suggests that inflammation plays a primordial role in atherogenesis and is closely associated with the major histocompatibility complex (MHC) (human leukocyte antigen \[HLA\] in humans) molecules. HLA genes are located in 6p21.3, the proteins encoded by these HLA genes have a major role to play in antigen presentation and inflammatory pathways. HLA involvement in inflammation is mainly associated with the HLA-dependent activation of T cells. studies reported that the susceptibility to CAD is related with the polymorphisms in HLA-DRB1. The above evidence indicates that the polymorphisms in HLA class II are associated with the risk of CAD . This study research investigate three objects , firstly what is the similarity of the coronary artery lesions according to the compatability of HLA alleles between the first degree relatives who went angiography before , secondly is there any relation between HLA subtype allels and the coronary artery (RCA ?LAD ? ,CX? and can such a relation be responsible from the lesions in this artery ,finally is there any relation between HLA subtypes and turkish race coronary artery disease

* first degree relative without any angiyography history before for patients who admitted as acute coronary syndrome
