Predictive accuracy of coronary artery calcification and abnormal exercise test for coronary artery disease in asymptomatic men.

摘要: To determine the predictive accuracy of fluoroscopically detected coronary artery calcification (CAC) and a positive submaximal exercise test, 129 asymptomatic men were screened; 13 had both test (greater than or equal to 1.0 mm ST-segment depression). These studied at arteriography. They mean age 44 years (range 41-56 years); none history symptoms heat disease all normal resting ECGs entry. CAC was in one 10 men, two arteries three man. Coronary (CAD) considered clinically significant if any major branch narrowed > 50%. arteriography revealed 12 with CAD (one-vessel four, two-vessel five three-vessel men) man minor one-vessel CAD. The 100% for 92% location correlated, but absence did not rule out presence Furthermore, indicate highest stenotic (most occlusive) lesions seen Follow-up patients 36 months; developed typical angina patient transmural myocardial infarction. This study suggests that middle-aged non-hyperlipidemic male is very high (100% CAD) predict an early appearance infarction previously men.
