Fig. 2. Multivariate analysis showed that HR and systolic (sBP) and diastolic (dBP) arterial blood pressure are predictive factors for elevation in cTnI levels. The risk of myocardial injury was 100% in the presence of all three factors, 75% in the presence of any two of the three, 38% in the presence of any one of the three, and 0% in the absence of all risk factors.
