title: [Coronary angiography: indications, results and complications in 5.000 consecutive patients].
abstract: BACKGROUND
  There are guidelines about equipment, premises, personnel, indications and complications rates for coronary angiography, that every center performing this procedure should adhere.
  
  
  OBJECTIVE
  To report the experience with 5.000 coronary angiographies and to assess the compliance of the center with the current guidelines.
  
  
  METHODS
  Prospective registry of 5.000 patients aged 60+/-11 years (3.475 males) subjected to coronary angiography since 1992, assessing all aspects of the procedure with special emphasis on complications.
  
  
  RESULTS
  The indications for 80% of procedures was suspected coronary atherosclerosis. The main risk factors were hypertension and smoking. Coronary atherosclerosis was demonstrated in 62%, mainly one vessel disease. These were two deaths due to the procedure (0.04%), three patients (0.06%) had an acute myocardial infarction or a stroke. These figures are lower than referential values.
  
  
  CONCLUSIONS
  In this center, coronary angiography is a safe procedure, with complications rates that are even lower than referential values.
