title: Success rate and safety of coronary angiography and angioplasty via radial artery approach among a Chinese population.
abstract: OBJECTIVE
  To find out the safety and success rate of transradial coronary angiography and angioplasty among a Chinese population.
  
  
  METHODS
  This was a prospective study performed on 2845 consecutive patients in a single interventional center at the first affiliated hospital, Nanjing Medical University, in Nanjing from August 2012 to July 2013. Allen's test was carried out on all patients who were involved in the study. Patients with abnormal Allen's test, cardiogenic shock, those on hemodialysis, and foreigners were excluded from the study. Our goal was to determine the efficacy and complications of coronary angiography (CAG) and percutaneous coronary intervention (PCI) through the radial approach in our local population.
  
  
  RESULTS
  The mean age of our patients was 64 ± 7.5 years with 1628 males (57.2%) and 1217 females (42.8%). A total of 1537 patients (54.0%) were hypertensive, while 501 patients (17.6%) were diabetic. Six patients (0.002%) had previous coronary artery bypass surgery. None of our patients had any bleeding disorder. A total of 1416 CAGs (49.8%) and 1429 PCIs (50.2%) were performed. The success rate was 97.6% for CAG and 96.3% for PCI. Seven patients (0.25%) had minor hematoma and 49 patients (1.7%) had reduced radial pulse 3-4 hours post procedure.
  
  
  CONCLUSIONS
  Transradial coronary intervention is safe and practical. It should be favored over femoral artery as an initial access point.
