PEREZ, Luis et al. Radial artery access to perform primary angyoplasty in acute myocardial infarction. Rev Chil Cardiol [online]. 2011, vol.30, n.2, pp. 125-130. ISSN 0718-8560. doi: 10.4067/S0718-85602011000200005.
Background: Radial access (RA) has been shown to help reduce vascular complications of coronary ar-teriography and angioplasty (PTCA). However, little experience has been reported with RA to perform primary PTCA in ST elevation acute myocardial infarction (STEMI). Since December 2007, we selected RA as a first option for primary PTCA in STEMI. Aim: to determine whether RA is as effective, safe and expeditious as femoral access (FA) in primary PTCA for STEMI Method: we performed a retrospective review of our database of all patients undergoing primary PTCA in our laboratory from Sept 2005 through August 2009. We compared all patients who had a PTCA using a FA to those in whom the RA was used. The door to balloon time, angiographic results, clinical success rate and complications related to the vascular access were compared between groups. Follow-up was based con clinical visits and phone calls. Values are expressed as mean and SD. Results: 375 patients had an FA (75%) and 118 an RA (25%). Mean age was similar in both groups (61±12 vs 62±12, respectively, NS). Selected clinical characteristics did no differ between groups. Door to balloon time was 62±37 min for FA and 61±29 min for RA (NS). Clinical success rate exceeded 94% in both groups. Vascular complications occurred in 3% in the AF group. No vascular complications were observed in the RA group. Thirty day overall mortality rates were 5.2% in FA and 4.0% in RA (NS). Conclusion: Radial access can be used for primary PTCA in STEMI with similar success rates and lower incidence of vascular complications, when compared to the traditional femoral access.
