OR and P values were derived from logistic regression analyses.
RPP response cutoff is 4402 beat x mmHg / min.
PAT ratio cutoff is 0.68.
Multivariate analysis 1: RPP response, PAT ratio and CSIMI were all included in one model as predictors of MSIMI.
Multivariate analysis 2: Multivariate analysis 1 + adjustment for age, gender, race, body mass index, diabetes, hypertension, myocardial infarction, beta blocker use and resting RPP.
Abbreviations: OR: odds ratio. CI: confidence interval. RPP: rate pressure product. PAT: peripheral arterial tonometry. CSIMI: Conventional stress induced myocardial ischemia.
