Sixty nondiabetic coronary artery disease (CAD) patients submitted to coronary angiography were asked to rate (score 0 to 20) pain intensity (RPI) during their last major anginal episode having occurred prior to coronary angiography. This parameter was examined in relation to other variables of CAD and to psychological features. Stepwise regression analysis revealed that RPI was not related to New York Heart Association (NYHA) classification of angina or to angiographic variables. Yet, RPI was found to be significantly affected by psychological features: higher RPI scores were reported by low state anxiety patients (P=0.008), by Type A coronary-prone behavior patients (P=0.02) and by patients with high depression (P=0.03).
