Data are presented as median and quartiles for continuous variables except age which is median and range, or number of patients and percentage for dichotomous variables. LAD Left anterior descending coronary artery; RCA Right coronary artery; LCx Left circumflex coronary artery; TIMI Thrombolysis in myocardial infarction; PCI Percutaneous coronary intervention.
