Abstract
Summary Introduction: Drug eluting stents (DES) were introduced in clinical routine to reduce neo- intimal hyperplasia and thus restenosis. Aim of the present study was to analyse the impact of previous PTCA therapy on the clinical outcome of CABG-surgery in a single center experience. Patients and methods: Data of 411 consecutive patients undergoing isolated CABG-surgery within a 10-months period were analysed. 328 patients (79.8%) were previously treated by the in-house interventional cardiology team. Characteristics of patients with and without previous balloon angioplasty (PTCA) and/or stent were compared. Results: 72/328 patients (22%) were treated by percutaneous coronary intervention prior to CABG (14 had PTCA only (19.4%), 36 stents without PTCA (50%) and 22 PTCA and stents (30.6%)). Despite use of DES in 53 patients (91.4%), stent failure was found in 29.2% in the interventional treated collective. Patients treated interventionally were younger (63.0 ± 10.0 years vs 66.1 ± 9.7 y; p 60 IU/l) was more frequent in the PCI-group than in patients who underwent CABG without previous PCI (12.4% vs 6.3%; p <0.01). One year follow-up revealed no differences between the two groups as far as survival and freedom from reintervention were analysed. Conclusions: 80% of the patients who received interventional treatment before CABG-sur- gery presented with a stent. In one third, pa- tients were addressed to surgery, due to stent failure. We observed a higher incidence of perioperative myocardial ischaemia in pa- tients who underwent previous interventional treatment.
