Purpose. To study peculiarities of coronary artery atherosclerosis in male patients of yakut nationality ill with IHD.

Material and methods. In the cardiologic department of RH №1 – NCM 993 patients were hospitalized for 2004-2005, 582 of them diagnosed with IHD. 171 patients had acquired heart disease (AHD), 74 - congentital heart disease (CHD), 82 - arterial hypertension (AH) and the rest 84 – other diseases. Coronaroangiography was administered to 230 patients, including 129 subjects with IHD.

After verification of coronarosclerosis all patients were divided into 2 groups: 1 - yakuts (n=45, mean age 53,2±14,52); 2 - russians (n=45, mean age 53,7±14,5).

Conclusion. Our survey found the following prevalence of CA atherosclerosis pathology isolated or combined in the1st and 2nd groups: left anterior descending artery (LAD) - 79 and 86,7% accordingly, then the right coronary artery (RCA) - 56 and 77,8%, circumflex artery (CA) – 32,5 and 71,1%, obtuse margin artery (OMA) – 11,6 and 31,1%, diagonal artery (DA) – 11,6 and 2,2% and left main trunk (LMT) – 9,3 and 2,2%.

Multiple affection of CA was observed more frequently as compared with the isolated one. The narrowing of one vessel was seen in 42 and 20% of the 1st and 2nd groups accordingly, two vessels affected - 26 and 17,8%, 3> vessels – 32,5 and 62,2% accordingly.

In the 1st and 2nd groups the occlusion rate of LAD amounted 38 and 30,8%, RCA – 8,3 and 51,4%, CA – 14 and 3,1%, OMA – 20 and 14,3%, LMT occlusion in 1 patient (25%) in the 1st group.

Thus, LAD is affected more frequently alike in both groups. Suggesting less severity the CA affection is more proportious to yakuts.
