Abstract

OBJECTIVE: This study compares sensory-biological, cognitive-emotional, and cognitive-interpretational factors in predicting angina on an exercise treadmill test (ETT). METHODS: A total of 163 patients with ETT-induced ischemia and coronary artery disease in the National Heart, Lung, and Blood Institute Psychophysiological Investigations of Myocardial Ischemia study were given an ETT, during which 79 patients reported angina. We assessed the following as potential predictors of self-reported anginal pain: sensory-biological factors (β-endorphin reactivity, hot pain threshold, and maximal ST-segment depression), cognitive-emotional factors (negative affect and symptom perception), and cognitive-interpretational factors (self-reported history of exercise-induced angina). Models were covariate adjusted with predictors examined individually and as part of component blocks. RESULTS: Logistic regression revealed that history of angina (odds ratio [OR] = 17.41, 95% confidence interval = 7.16-42.34) and negative affect (OR = 1.65, 95% confidence interval = 1.17-2.34), but not maximal ST-segment depression, hot pain threshold, β-endorphin reactivity, or symptom perception, were significant predictors of angina on the ETT. The sensory-biological block was not significantly predictive of anginal pain (χblock = 5.15, p = .741). However, the cognitive-emotional block (χblock = 11.19, p = .004) and history of angina (cognitive-interpretation; χblock = 54.87, p < .001) were predictive of ETT angina. A model including all variables revealed that only history of angina was predictive of ETT pain (OR = 16.39, p < .001), although negative affect approached significance (OR = 1.45, p = .07). CONCLUSIONS: In patients with ischemia, cognitive-emotional and cognitive-interpretational factors are important predictors of exercise angina.
