OBJECTIVE: The purpose of this study is to evaluate the in-hospital clinical outcome of patients with coronary artery disease who underwent transradial intervention (TRI) and analyze the predictors of clinical outcome.

METHODS: From May 2004 to May 2009, there were 16 281 patients who underwent transradial intervention, as well as 5388 patients who underwent transfemoral intervention (TFI) at our institution. The clinical characteristics, procedural characteristics, and in-hospital clinical adverse events were compared between TRI and TFI groups. Multivariable logistic regression analysis was performed to determine predictors of in-hospital major adverse cardiac events (composite of death, myocardial infarction, or target lesion revascularization) of TRI.

RESULTS: The annulations time was significantly longer for TRI than TFI (P < 0.01), fluoroscopy time, amount of contrast agent and procedural success rate (95.5% for TRI and 96.2% for TFI) were similar between the two groups. However, the rates of vascular complications (0.1% for TRI group and 1.3% for TFI group, P < 0.01), incidence of in-hospital major adverse cardiac events (1.6% vs. 3.8%, P < 0.01) and in-hospital death (0.2% vs. 0.4%, P < 0.01) were all significantly lower in TRI group compared with TFI group. The following characteristics were identified as independent multivariate predictors of in-hospital major adverse cardiac events of TRI: age ≥ 65 (OR: 1.98, 95%CI: 1.50 - 2.61, P < 0.01), prior myocardial infarction (OR: 2.14, 95%CI: 1.63 - 2.82, P < 0.01), use of drug-eluting stent (DES) (OR: 0.68, 95%CI: 0.47 - 0.98, P = 0.04), dissection during procedure (OR: 4.08, 95%CI: 2.28 - 7.33, P < 0.01), left main lesion (OR: 2.12, 95%CI: 1.09 - 4.13, P = 0.03), number of implanted stents (OR: 1.25, 95%CI: 1.09 - 1.43, P < 0.01), and total stented length (OR: 1.01, 95%CI: 1.00 - 1.02, P = 0.03).

CONCLUSIONS: In this large single-centre patient cohort, the transradial intervention is superior to transfemoral intervention in terms of in-hospital safety and efficacy. Age ≥ 65, prior myocardial infarction, use of DES, dissection during procedure, left main lesion, number of implanted stents and total stented length were identified as independent multivariate predictors of in-hospital major adverse cardiac events of TRI.
