The occurence frequency of stenosis in the left and right coronary arteries of incidence of different age groups of smoking and nonsmoking ischemic heart disease patients

Objective: In the world, coronary artery diseases (CAD) are located the first lines among death reasons. Ischemic heart disease (IHD), is the most frequently seen condition of CAD because of atherosclerosis. Therefore is aimed what the designated male and female (different age groups) ischemic heart patients, distribution who past coronary angiography (CAG) are determined stenosis and obstructions right and left coronary arteries. Materials and Methods: In this study, between 2007 february – 2013 january, we evaluated retrospectivaly, reports of patients who were made CAG. At the findings results, 300 women and 300 men total of 600 patients who had taken IHD were included in this study. To determine this, 25 - 69 in the range of age male and famele patients according to gender: 25 - 39, 40 - 54, 55 - 69 were divided in to age groups. 300 female and 300 male patients as 150 smokers and 150 non-smokers were subdivided. IHD grouping if anterior interventricular artery (AIA) and circumflex artery (CxA) which are main branches of left main coronary artery (LMCA) and right coronary artery (RCA) is plaque rate of below 30 %, occlusion no existent were considered. If plaque rate of over 30 % occlusion in our study statistical analysis was done using chi-square test which is a parametric test. Results: For the female patients who have RCA stenosis and occlusions according to gender is seen main full of difference. According to age group, with advancing age in RCA and main branches of LMCA seems to be increase stenosis and occlusions. In both gender groups, stenosis and occlusion of the RCA was determined to show a certain increase in smokers than non-smokers. This is a significant differance as statistically. According to gender female was seen to be more apt about RCA whit LMCA, AIA and CxA stenosis and occlusion. Conclusion: In the findings, stenosis and occlusions of coronary arteries were found to be effective that sex and age is important. In addition, cigarette affects the coronary arteries due to gender was concluded. As a result, it is believed that more comprehensive studies needs to be done.
