Abbreviations same as in Table 1 with the following additions:

^⁎Median (interquartile range) for all continuous variables.

^†mmHg = millimeters of mercury.

^‡g/dl = grams per deciliter.

^§Troponin values in the UK and Sweden are a mix of initial and peak. Peak troponin values in the US were 0.6 (0.2, 1.7) and 4.7 (1.5, 14.3) for troponin T and I, respectively.

^║ng/ml = nanograms per milliliter.

^¶Includes “T wave inversion” in RIKS-HIA and ACTION and “T wave changes only” in MINAP.

^#Includes “Normal”, “None”, and “Other” categories.
