PREDICTORS OF NORMAL CORONARY ARTERIES AT INVASIVE CORONARY ANGIOGRAPHY IN PATIENTS WITH STABLE ANGINA
Coronary angiograms are important in diagnostic workup of patients with suspected coronary artery disease. However, little is known about the clinical predictors of normal angiograms and whether this varies across different cardiac centers. Overall, 44% of patients with stable angina had normal catheterization. Atypical ischemic symptoms, the absence of diabetes, smoking history, younger age were associated with higher rates of normal catheterization. High prevalence normal angiograms in patients with stable angina agrees with previous foreign studies.
