One-year follow-up and quality of life in elderly patients after previous cardiac surgery

Objective. To study the one-year follow-up results after coronary artery bypass grafting (CABG), quality of life and factors affecting various components of health in elderly patients with coronary artery disease (CAD). Material and methods. The study included 90 patients with CAD aged ≥65 years (middle age 73.0 (69.0—76.4) years). All patients were eligible to on-pump CABG. One-year follow-up included adverse cardiovascular events, any surgery, and mortality. We used SF-36 questionnaire to study physical component summary (PCS) score and mental component summary (MCS) score before and in 1 year after CABG. Results. Annual postoperative survival was 97.8%. We found low PCS and MCS scores (≤41 points). We noted an improvement in MCS indicators in one year after CABG (p=0.019). PCS scores did not differ from baseline data (p>0.05). After one year, PCS and MCS scores were reduced (<50 points) with higher psychoemotional parameters compared to physical ones (p<0.001). Negative factors for MCS were any surgical interventions after CABG. PCS was negatively influenced by the same factor and in-hospital neurological complications after CABG. Conclusion. There was high annual survival after CABG in elderly patients with CAD (97.8%). We found an improvement in mental component of health and no positive dynamics in physical component. The factors negatively affecting physical aspect of health in 1 year after surgery were in-hospital neurological complications and any surgical interventions after CABG. Only the last factor negatively influenced psychoemotional status after CABG.
