Background: An increasing number of patients who undergo coronary artery bypass grafting(CABG) have a history of coronary stent implantation. This study aims to assess perioperative and medium-term follow-up outcomes in patients in whom CABG was preceded by coronary stent implantation within two years before operation., Methods: One hundred and sixty two patients undergoing CABG after previous stent placement (PCI + CABG group) were compared to 149 who had CABG without PCI in the past (CABG group). Clinical, angiographic and perioperative outcome data were compared. The three year follow-up comprised data on number of deaths and the presence of anginal symptoms., Results: In both groups the extent of coronary artery disease was comparable, but more patients in the PCI + CABG group had a history of myocardial infarction. Perioperative outcome data did not differ between the groups except for a higher number of vessels considered infarct-related grafted in the CABG group. Patients operated on up to three months after PCI had more extensive coronary heart disease than those operated on later. They also had a significantly shorter operation time. This group also showed a trend towards less postoperative bleeding, less rethoracotomy and less low cardiac output syndrome. In a three year follow-up, 48 (30%) patients in the PCI + CABG group reported presence of angina compared to 28 (19%) in the CABG group (p = 0.04)., Conclusions: Previous PCI does not significantly influence the CABG outcome. In mediumterm follow-up, freedom from anginal symptoms is less likely in patients in whom CABG was preceded by stent implantation.

Introduction: There are many patients aged over 80 years among those hospitalised for coronary artery disease (CAD). The unanswered question is whether invasive treatment of such patients is effective and safe., Aim: To assess and compare one-year clinical outcomes after percutaneous coronary angioplasty (PTCA) and surgical coronary artery bypass grafting (CABG) in patients aged over 80 years and in younger patients., Method: There were 63 patients aged over 80 years suffering from CAD who underwent either PTCA or CABG. The control group consisted of 40 patients aged 60-65 years treated in the same way. Data on medical history, cardiovascular risk factors, and angiographic findings were analysed. The potential risks of the procedures, post-procedural complications as well as the clinical status at the end of one-year follow-up were evaluated., Results: There were 24 surgical revascularisation procedures and 39 PCIs performed in the very old patients. Stable angina was found in 29 cases, unstable angina in 19 and acute myocardial infarction in 15 patients. There were three in-hospital deaths and 18 periprocedural complications were noted. During the one-year follow-up period six deaths occurred, persistent or recurrent angina was found in 11 patients after PCI and two after CABG. There were no deaths in the control group and the incidence of minor complications was similar to the senile group. In younger patients who underwent CABG, CCS class at one year was lower than in the very old ones., Conclusions: The invasive treatment of coronary artery disease in octogenarians is feasible with satisfactory results and acceptable procedural risks.
