title: [Initial experience in the management of myocardial infarction with primary angioplasty: results of the activity in two hospitals of the Turin area without on-site cardiac surgery].
abstract: BACKGROUND
  Reperfusion therapy of ST-elevation myocardial infarction (STEMI) with primary coronary angioplasty (PTCA) is becoming an accepted therapeutical strategy because of a lower incidence of reinfarction, of hemorrhagic stroke and for a greater reduction of the infarct size in comparison to thrombolytic therapy. In this study we evaluated the feasibility and the effectiveness of such a strategy in two hospitals without on-site heart surgery but with a high volume of admission for acute coronary syndrome and a high caseload of elective interventional procedures.
  
  
  METHODS
  Since January 2001 we started a program of primary PTCA for all STEMI patients presenting within 12 hours of symptom onset. An interventional team (physician, nurse and technician) were on call in a 24/7/365 fashion. Aspirin, heparin and abciximab were administered in the emergency room to all patients. Immediately after the procedure patients were given clopidogrel.
  
  
  RESULTS
  Up to December 2003, 464 patients (mean age 63 +/- 12 years, 19.8% female) underwent primary PTCA. The symptom-emergency room interval was 3 +/- 3.9 hours, while the door-to-balloon time was 52.5 +/- 39.4 min. A TIMI 0-1 flow in the infarct-related artery was present in 55.8% of patients. Seventy patients (15.1%) presented with shock. In 430 patients (92.7%) a TIMI 3 flow was restored followed by a reduction in ST-segment elevation > 50% in 356 patients (76.7%). Total in-hospital mortality was 4.9% (23 out of 464 patients). The mortality of patients with shock was 31.4% (22 out of 70 patients). Two patients (0.4%) underwent emergency bypass. Four patients (0.8%) were electively referred to surgery prior to discharge in order to complete revascularization, which could not be obtained with further PTCA. The rate of major hemorrhagic complications was 0.8%.
  
  
  CONCLUSIONS
  Primary PTCA for STEMI is a reperfusion strategy feasible and effective even in hospitals without on-site heart surgery, provided that a high volume of routine and emergency interventional procedures is maintained and when such a strategy is timely performed according to international guidelines.
