Predicting results of coronary angiography

This study compares the ability of various risk factor combinations to predict the extent of coronary artery disease found on coronary angiography. Risk factors were measured in 99 patients prior to coronary angiography. Clinical, epidemiological, psychosomatic, and combined orientations were compared as to their ability to predict angiography results. The clinical orientation was the most successful in predicting vessel disease (p less than .0001), followed by the epidemiological model, which was also successful (p less than .03). In contrast, psychosomatic factors were not accurate predictors of vessel disease. By combining all of the orientations, the accuracy of prediction is improved.
