| Popis: | We evaluated the coronary arteries on computed tomography (CT) scans of the chest and on coronary angiograms of 27 patients who underwent both studies. We related the presence or absence of coronary artery calcification on CT to percentage stenosis on angiogram. For the left anterior descending artery (LAD), the likelihood of calcification rose proportionately with degree of stenosis; this was less true for the circumflex, and not true for the right coronary artery (RCA). The sensitivity of CT in detecting coronary artery calcification in patients with angiographic criteria of significant coronary artery disease (CAD) was 78% for the LAD, 63% for the circumflex, and 16% for the RCA. Specificities were 78%, 80%, and 100%, and positive predictive values were 88%, 83%, and 100%. The high positive predictive values suggest that coronary artery calcification diagnosed by chest CT has a high correlation with clinically significant CAD. Therefore, when we detect such calcification in a patient without documented heart disease, we suggest that a cardiac workup is indicated. |
