[Invasive diagnosis of ischemic heart disease and percutaneous coronary angioplasty in the Czech Republic in 1992].

The rates of 450 diagnostic coronary angiographies and 60 PTCA procedures per one million population performed in the Czech Republic in 1992 are 30% of actual minimal need for the former, and 15% of the necessary PTCA procedures. The poor performance has an adverse effect on indication criteria as well as on the potential for timely interventions in patients with chronic IHD and, especially so, in patients with acute coronary events. To improve the current situation, it is critical to boost the throughput of the existing centres.
