Percutaneous transluminal coronary angioplasty and use of drug-eluting stent in Shiraz catheterization centers during 2006

ABSTRACT

The dominant role of percutaneous transluminal coronary angioplasty [PTCA], especially with drug-eluting stent is obvious in alleviating symptoms and improving life quality of patients with coronary artery disease.We analyzed a total 2267 angioplasty cases [906 women, and 1361 men] in six public and private catheterization centers in Shiraz, from January 2006 to January 2007. A] Pure old balloon angioplasties were performed only in 12 cases [0.52%]. B] Drug-eluting stents [53.7%] were placed more frequently than Bare-metal stents [46.3%]. There was 13% increase in placing drug-eluting stent during 2005. C] Drug-eluting stents were used in 50.0% and 54.9% of patients in public and private hospitals, respectively. D] In Shiraz centers, Cypher model was used more often than other models [29.1%]. E] Single-vessel disease PTCAs were done in 65.5% of patients followed by two [27.0%], and three-vessel diseases [7.5%]. We recommend the increasing use of drug-eluting stents especially in patients with three-vessel disease. However, the use of first generation of drug-eluting stents would increase the chance of subacute thrombosis. It is also essential to carry out especial surveys about drug-eluting stents in Iran and Middle East
