The value of chest pain during the exercise tolerance test in predicting coronary artery disease.

UNLABELLED

The predictive power of 10 common exercise test parameters compared with coronary angiography was studied. Only the exercise electrocardiogram (EXECG), maximal rate pressure product (MAXRPP), and exercise chest pain (EXCP) contributed unique predictive information with the emergence of two interactions involving EXCP (EXCP.EXECG and EXCP.MAXRPP).

IN CONCLUSION

(1) EXCP appears to be a more serious finding only in those higher risk individuals with either a positive EXECG or lower MAXRPP; (2) EXCP and its interactions may help discriminate between anginal and nonanginal, exertional chest pain, and (3) the contradictory results found when EXCP was allowed to interact may explain conflicting results in previous multivariate models regarding the predictive significance of EXCP.
