MI, abdominal aorta aneurysm, intracranial aneurysm restenosis and peripheral arterial disease, by assessing the presence or absence of alleles of certain polymorphic markers found to be associated with cardiovascular disease. The invention further relates to kits encompassing reagents for assessing such markers, and methods for assessing the probability of response to therapeutic agents and methods using such markers.
