Results of endovascular revascularization with the use of stents after coronary bypass surgery in patients with ischemic heart disease

Aim. To compare results of stenting in patients with and without prior coronary artery bypass grafting (CABG). Methods. In 21 patients after CABG stents were implanted both in venous grafts and native vessels (secondary revascularization) and in 25 patients without history of CABG native vessels were stented (primary revascularization). Results. Primary revascularization: there was 1 periprocedural non Q wave myocardial infarction (4%), angina disappeared in 88% and recurred in 1 year in 24% of patients; one year restenosis rate - 18.2%. Secondary revascularization: 1 periprocedural non Q wave (4.8%) and 1 Q wave (4.8%) myocardial infarction. Angina disappeared after stenting in 90.5% and recurred in 1 year in 19% of patients, one year restenosis rate - 17.6%. Conclusion. Both primary and secondary revascularizations were highly effective. However secondary stenting was associated with more frequent acute complications.
