title: Ambulatory discharge after transradial coronary intervention: Preliminary US single-center experience (Same-day TransRadial Intervention and Discharge Evaluation, the STRIDE Study).
abstract: BACKGROUND
  Although the safety and cost-effectiveness of same-day discharge after uncomplicated transradial percutaneous coronary intervention (TR-PCI) is well established in Europe and Asia, such data are not available for US patients.
  
  
  METHODS
  All patients who underwent TR-PCI at our high-volume US medical center between 2004 and 2007 were included in this study. The primary end point was in-hospital adverse clinical outcomes between 6 and 24 hours postprocedure.
  
  
  RESULTS
  A total of 450 patients were included in this study (aged 59 +/- 11 years). Of these, 13% were female, 27% were diabetic, 6% had peripheral vascular disease, and 5% had chronic kidney disease. Procedural indications included stable angina (49%), unstable angina (31%), non-ST elevation myocardial infarction (NSTEMI) (17%), and ST elevation myocardial infarction (STEMI) (3%). All patients received an intra-arterial cocktail of heparin, verapamil, and nitroglycerin, and 13% of patients received glycoprotein IIb/IIIa inhibitors. Seven percent of patients had 3-vessel disease, 3% had bypass grafts stenoses, and 20% had class B(2)/C lesions. Procedural success rate was 96%. A total of 24 (5.3%) postprocedural complications were observed; however, none occurred between hours 6 to 24, the time differential between same-day and next-day discharge. Thirteen patients (2.9%) experienced significant complications within the first 6 hours (MI, urgent repeat revascularization, and ventricular tachycardia). Eleven (2.4%) spontaneously resolved minor access complications developed. There were 12 same-day discharges according to the operators' discretion; none required readmission.
  
  
  CONCLUSIONS
  Although a low incidence of complications did occur, none would have been impacted by same-day discharge. Those observed before 6 hours would have prevented early discharge, and those occurring after 24 hours would have been unaffected by routine next-day discharge. This observational study demonstrated the safety and feasibility for a prospective evaluation of ambulatory TR-PCI in an American practice setting.
