Statistically significant ( ). TFA = transfemoral artery access. TRA = transradial artery access. PCI = percutaneous coronary intervention. CABG = coronary artery bypass graft. GPI = glycoprotein IIb/IIIa inhibitor. STEMI = ST-segment elevation myocardial infarction. NSTEMI = non-ST-segment elevation myocardial infarction. LAD = left anterior descending. LCx = left circumflex. RCA = right coronary artery. BMS = bare metal stent. DES = drug-eluting stent. TIMI = thrombolysis in myocardial infarction. |
