title: [Use of coronary angioplasty in acute myocardial infarction without previous use of thrombolytic agents. Analysis of 201 patients].
abstract: OBJECTIVE
  To evaluate the experience with the use of primary PTCA in the set of acute myocardial infarction (AMI) without the previous administration of thrombolytic agents.
  
  
  METHODS
  Two hundred and one patients with AMI, aged 35 to 86 years (mean = 57.2). There were 83.5% men. Twenty patients were older than 70 years and 48.2% had an anterior AMI. PTCA was performed early in the AMI, with a delay no longer than 12 hours. In 95%, it was done solely to the infarct related artery. Seventy percent patients were in Killip class I, 21% in class II, and 8% in classes III and IV (more than 50% of this subset of patients were in cardiogenic shock).
  
  
  RESULTS
  Primary success was achieved in 84.5%. In hospital mortality was 5.9%, and there were 7% reinfarctions. Among the 84 patients who underwent a late cinecoronariography study, there were 19% restenosis and 8.3% reocclusions. In the long term follow up 75% were asymptomatic. Repeat PTCA was required in 10.2% of the cases, late coronary surgery was performed on 10.8% of the patients, and post-hospital cardiac mortality was 8.8% during an average follow up of 28 months (range 2-72 months).
  
  
  CONCLUSIONS
  Primary PTCA is a effective way of reperfusion in the AMI, with a high primary success, low complications rate and without any major contraindications.
