Coronary artery calcification is considered as a valuable index in detecting CAD using a noninvasive technique. This study was conducted to determine the correlation between coronary artery calcification and coronary artery stenosis in patients with typical chest pain.METHODS: This cross-sectional study was conducted on 760 patients suffering from typical chest pain, in Chamran Hospital, Isfahan, Iran. The patients  were all candidates for coronary angiography and were studied for the calcification of coronary artery by fluoroscopy. All patients signed a consent form after the whole procedures were fully explained to them. A fluoroscopic movie was taken from patients (after exposing, and before inserting the angiographic catheter), then the angiography was conducted using Judkins technique.  The results of fluoroscopy and angiography were recorded by two cardiologists separately. The presence of any significant stenosis greater than 75% was considered as a sign of severe CAD. The data was analyzed by chi-square test.RESULTS: Abnormal angiogram was found in 402 patients (59.2%). Positive and negative predictive values for calcification were 81.8% and 26%, respectively. Positive and negative predictive values were respectively 87.1% and 63.4% in females, and 79.7% and 47.3% in males. The highest predictive value (100%) was seen in patients under 40 years old. Coronary calcification in patients with abnormal coronary angiogram was found to be 5.4 times greater than those with normal angiogram. CONCLUSION: Considering the high predictive value of coronary artery calcification in fluoroscopy, it can be used as a replacement for screening coronary involvement.Keywords: Calcification, Coronary Vessels, Coronary Disease, Diagnosis UR - https://arya.mui.ac.ir/article_10271.html L1 - https://arya.mui.ac.ir/article_10271_d4149ed3e7a784dd3027361184dc68c3.pdf ER -
