Twelve patients were excluded due to follow-up loss during a 1-year follow-up, and 98 patients were excluded due to follow-up loss during a 3-year follow-up. Thus, 488 and 402 patients were finally included in the final 1- and 3-year follow-up cohorts, respectively.
MI indicates myocardial infarction.
