Palmaz-Schatz metallic coronary artery stent data

Japanese university researchers reported on the ability of stents to reduce rates of restenosis after angioplasty in 143 patients with 147 coronary artery lesions. The rate of survival free of myocardial infarction, bypass surgery, and repeated coronary angioplasty for stented lesions was 74.6 percent at three years.

After 14 months, revascularization of the stented lesion was necessary in only 3 patients (2.1 percent), whereas coronary angioplasty for a new lesion was required in 11 patients (7.7 percent), according to the study published in the New England Journal of Medicine. ...
