    Abstract:
    OBJECTIVE: To compare the in-hospital clinical outcome of patients with coronary artery disease in different age groups [< 65 years (younger), 60 to 79 years (older), and ≥ 80 years (octogenarians)] underwent transradial intervention (TRI) so asto analyze the predictors of adverse events. METHOD: From May 2004 to May 2009, a total of 16 293 patients underwent transradial intervention at our institution. The in-hospital outcome for patients in different age groups after TRI was investigated. Multivariable logistic regression analysis was performed to determinate the predictors of in-hospital major adverse cardiac events (MACE) (composed of death, myocardial infarction or target vessel revascularization). RESULTS: Angiographic success rates were not different (97.5%, 97.4%, 98.1%, P > 0.05) between 3 groups. However, the rates of procedural complications became progressively higher with age group (0.8%, 1.2%, 4.0%, P < 0.01). In-hospital MACE (1.3% vs 2.2% vs 7.5%, P < 0.01) and mortality (0.1% vs 0.3% vs 2.9%, P < 0.01) increased incrementally with age group. Aad it was associated with a significant decrement of DES (92.0%, 89.6%, 57.3%, P < 0.01). The following characteristics were identified as independent multivariate predictors of in-hospital major adverse cardiac events: age ≥ 80 (OR 6.26, 95%CI: 3.33 to 11.74; P < 0.01), prior myocardial infarction (OR 2.19, 95%CI: 1.66 to 2.88; P < 0.01), left main lesion (OR 2.02, 95%CI: 1.04 to 3.91; P = 0.04), age of 65 to 79 (OR 1.83, 95%CI: 1.37 to 2.43; P < 0.01), number of implanted stents (OR 1.31, 95%CI: 1.15 to 1.50; P < 0.01), total stented length (OR 1.01, 95%CI: 1.01 to 1.02; P = 0.03), and use of DES (OR 0.59, 95%CI: 0.39 to 0.89; P = 0.01). CONCLUSIONS: The younger and older patients undergoing TRI have a more favorable in-hospital outcome. However the octogenarians has a substantially higher risk of in-hospital MACE.
