Figure 2 HRs and 95% CIs of Factors in the Multivariable Model by Anginal Status

There was no observed interaction between the identified outcome predictors in the model and anginal status at presentation, irrespective of the periprocedural applied definition of myocardial infarction (MI). (A) Results based on non–Q-wave MI defined as any creatine kinase (CK) or CK-myocardial band elevation 3 times the upper limit of normal are shown, with an overall p value of 0.66 for testing interaction. (B) Results based on non–Q-wave MI defined as any CK or CK-myocardial band elevation beyond the upper limit of normal are shown, with an overall p value of 0.58 for testing interaction. Blue = stable angina; red = unstable angina. ACE = angiotensin-converting enzyme; CI = confidence interval; DS = diameter stenosis; HR = hazard ratio; LCX = left circumflex artery.
