*All models were adjusted for age and sex.
†After inclusion of each of the extra variables, HR for new hyperenhancement remained >2.6 with p value <0.05.
‡0.2 μg/l equals the 99th centile of the lower limit of quantification.
¶After inclusion of each of the extra variables, HR for new hyperenhancement (continuous) remained >1.08 with p value <0.05.
LVEF, denotes left ventricular ejection fraction; PMI, procedure-related myocardial infarction according to the ESC/ACC/AHA/WHF guidelines.
