title: [Primary angioplasty in acute myocardial infarction: experience and results in the first 1,000 consecutive patients].
abstract: BACKGROUND
  One of the biggest debates in modern cardiology regards the relative merit of primary percutaneous transluminal coronary angioplasty (PTCA) versus thrombolysis for the treatment of acute myocardial infarction with persistent ST-segment elevation. After the excellent results with primary PTCA in trials and meta-analyses, the next question is whether such results might be duplicated in "real world" conditions.
  
  
  METHODS
  Between January 1995 and April 2003, 1000 consecutive patients with acute myocardial infarction, out of 2272 (44%) with ST-segment elevation admitted to the coronary care unit at the Cardiology Department of the S. Anna Hospital, were treated with PTCA. Our Institution is a medium-high volume center, without on-site surgery. Usual clinical and interventional practice, adjunctive antithrombotic therapy and results are described in this paper.
  
  
  RESULTS
  Primary PTCA has been performed in 825 patients (75%) out of 1095 undergoing emergency angiography, "facilitated" in 140 (13%), rescue in 35 (3.2%). Eighty patients of the "facilitated" PTCA group had been pre-treated with tissue-type plasminogen activator 50 mg i.v. bolus, 50 with abciximab and 10 with reduced doses of fibrinolytic and abciximab. One hundred and seventy patients (16%) had been transferred to our Institution from community hospitals. Nine patients out of 1000 undergoing PTCA (0.9%) have been transferred immediately after the procedure (bail-out, failure) to perform urgent coronary artery bypass grafting. PTCA has been completed by stenting in 919 patients (92%). The median door-to-balloon time was 58 min (25th-75th percentile 49-71). The in-hospital total mortality rate was 4.9% (49 deaths): 5.3% (44 deaths) in the primary PTCA group, 2.1% (3 deaths) in the "facilitated" PTCA group (p = 0.042), and 5.7% (2 deaths) in the rescue PT-CA group. Early reinfarction rate was 1.5% (15 cases). The median time to hospital discharge was 10 days (25th-75th percentile 7-14).
  
  
  CONCLUSIONS
  Since 9 years, our practice in the treatment of acute myocardial infarction with persistent ST-segment elevation is going on extending the use of primary PTCA, integrating pharmacological and mechanical options in selected cases.
