The study included 367 patients with stable ischaemic heart disease. The control group included 660 subjects who were not diagnosed with ischaemic heart disease. A relationship between the presence of atherosclerotic lesions in the coronary angiogram and the polymorphism in the gene coding for paraoxonase PON 2 \(PON 311\) was documented in this distribution. This is a relation between PON 311 gene polymorphism and the pres\-ence of type C lesions in coronary arteries independently of the extent of artery narrowing. The demonstrated relation results from the impact of a single PON 311 gene polymorphism and remains statistically significant after tak\-ing into account in the analysis the risk factors for atherosclerosis de\-velopment. In case of atherosclerotic lesions confirmed by angiography, no rela\-tionship was found between the degree of severity, localization and number of arteries with a significant narrowing and the polymorphisms in genes coding for paraoxonases and angiotensin\-converting enzymes. An association was also documented between the polymorphism in genes coding for angiotensin\-converting enzyme \(ACE\) and higher incidence of arterial hypertension and current tobacco smoking No associations were found between studied polymorphisms and dia\-betes, obesity and hypercholesterolemia.Furthermore, no relationship was documented between the presence of atherosclerotic lesions in the coronary angiogram and the other exam\-ined gene polymorphisms \(PON 1 and PON 2 \(PON 55, PON 192\) encoding paraoxonases and angiotensin\-converting enzymes \(ACE I\/D\). We demonstrated a relation between some risk factors and the aspect of atherosclerotic lesions in the coronary angiogram."]
