Abstract
Four hundred and fifty two patients (pts) underwent coronary angiography (CA) and EBCT at 5 different centers between April 1989 and Dec. 1993. EBCT studies were analyzed by a cardiologist, blinded to CA and clinical data, using a specialized work station. A follow-up phone survey was completed in 53%. Three other cardiologists. blinded to CA and EBCT, reviewed records for all deaths and hospital admissions for chest pain or suspected myocardial infarction. They determined that 9 CHD deaths and 6 acute infarctions had occurred in 31 ± 14 mos. The quartile EBCT score distribution for events was:QuartileRange of Scores# of Pts# of Events1(0–6)6002(6–92)6033(92–400)6064(<400)606 Logistic regression including age, sex, CA findings and log (EBCT score) showed that only log (score) predicted events. EBCT coronary calcium predicts CHD events in pts undergoing angiography but pts with lower scores can also suffer events.
