We have reviewed the results of our experience with the use of miniaturized (Mini-CPB) versus conventional (C-CPB) cardiopulmonary bypass in coronary artery bypass surgery (CABG). This study included 365 patients who underwent CABG with C-CPB and 101 patients with Mini-CPB. In-hospital mortality was lower in the C-CPB group (1.4% vs. 3.0%, P = 0.38). A better, but not statistically significant, immediate outcome was observed in the C-CPB group as indicated by a shorter length of stay in the intensive care unit as well as a lower incidence of combined adverse end-point. However, this was probably due to significantly higher operative risk in the Mini-CPB group (logistic EuroSCORE: 8.5 ± 10.0 vs. 4.6 ± 7.1, P

Background and Aims: Stroke has remained one of the most frustrating complications in coronary artery bypass surgery (CABG). The purpose of this study was to describe the incidence and correlates of stroke in CABG patients operated on in a hospital with low annual volume of open-heart surgery procedures. The aim was moreover to clarify subsequent outcome and self-reported satisfaction-based quality of life of patients who had experienced a stroke. Material and Methods: The material was a cohort of 1318 consecutive CABG patients operated on over a 6-year period. Data was collected prospectively but the final analysis was retrospective. Questionnaires supplemented the estimation of survival and subsequent functional status. Results: The incidence of stroke was 2.6 %. Age >70 years, chronic obstructive pulmonary disease (COPD), peripheral vascular disease (PVD), cerebral vascular disease (CVD), number of aortic anastomoses and significant atherosclerosis of the ascending aorta were univariate predictors of stroke. Postoperative stroke was experienced in 55.9 of cases delayed appearing from 2nd postoperative day on. Stroke patients had a higher rate of mortality (14.7 % vs. 1.0 %, p = 0.001) and poorer survival than no-stroke patients (82.4 % and 97.4 % at one year and 61.2 % and 89.7 % at six years, p < 0.001). Conclusions: The incidence of stroke seems to be on the same level in CABG patients from a low volume hospital as in reports from centres with a high volume of annual procedures. Stroke predicts higher mortality, longer intensive care unit (ICU) stay, longer hospitalisation and poorer survival. A relatively high number of stroke patients need permanent institutional care. Satisfaction-based quality of life in CABG patients also remains on a lower level in comparison to patients without neurological complications.

Background and Aims: Understanding and objective assessment of risks is crucial in cardiac surgery. The aim of this study was to assess the influence of peripheral vascular disease (PVD) on morbidity, mortality and outcome in coronary artery bypass grafting (CABG) patients. Material and Methods: The ankle-brachial pressure index (ABPI) was used as indicator of PVD and was measured in 178 CABG patients. Two groups were established: 1. normal ABPI (0.9–1.3) (n = 136) and 2. lowered ABPI (< 0.9) (n = 35). The mean follow-up was 26 months. Results: The presence of PVD was 20.5 %. Patients with PVD were older (p < 0.05), more often of female sex (p < 0.05), had higher Higgins's risk score (p = 0.001) and more often intermittent claudication (IC) (p < 0.001). PVD significantly predicted atrial fibrillation (FA) (p < 0.05) and relatively postoperative myocardial infarction (MI) (p = 0.058). Conclusions: The presence of PVD is relatively high in CABG patients and increases with age. PVD predicts some morbidity but seems to have fairly little influence on short-term or middle-term outcome of CABG patients. ABPI may be of only limited value in identifying patients with high operative risk in CABG.
