Effect of Coronary Artery Calcification Score by Lifestyle and Correlation With Coronary Artery Stenosis by Multidetector Computed Tomography.
OBJECTIVE
This study examined the effect of coronary artery calcification score by lifestyle and correlation with coronary artery stenosis in persons who underwent coronary artery computed tomography (CT) angiography among health examinees for heart diseases in Korea.


METHODS
The study included 506 subjects (256 men and 250 women) who underwent coronary artery CT angiography among health examines for heart diseases at the Incheon Branch of the Korea Association of Health Promotion between January 2, 2014, and December 31, 2014. The demographical variables of the subjects were determined by frequency analysis, and the difference by sex was compared and analyzed using χ independence test. Independent 2-sample t test was performed to determine any difference in main factors by coronary artery calcification.


RESULTS
According to the results, 175 (34.6%) had calcification, men showed statistically higher scores than women, and calcification seemed higher in those who were older, taller, heavier, and thicker in waist. Regarding blood pressure, calcification was shown if contraction phase and relaxation blood pressure was higher, blood sugar before meal was higher, and neutral fat was higher. By lifestyle, calcification seemed to be higher in those with more alcohol drinking per week, long past smoking years, and higher smoking amount per day in the past and present. In addition, coronary artery stenosis rate showed statistical correlation with calcification from the left anterior descending artery, right coronary artery, left circumflex artery, and left main coronary artery in sequence.


CONCLUSIONS
In conclusion, coronary artery calcification score CT is deemed to be a suitable method for the estimation of coronary artery stenosis with short examination time, low radiation exposure, and noninvasive method.
