Clinical analysis on octogenarians undergoing coronary artery bypass grafting

Abstract

Objective To investigate the clinical characteristics, evaluate the operative procedure and clinical results of octogenarians underwent coronary artery bypass grafting (CABG). Methods The retrospective analysis included the medical data on 19 patients aged 80 years or greater undergoing CABG at our department of cardiac surgery from June 2012 to May 2014.There were 15 male and 4 female patients, aging from 80 to 91 years with a mean of (82.7±3.3) years. Fourteen patients underwent cardiopulmonary bypass or on-pump CABG, three patients underwent off-pump CABG and two patients underwent beating heart CABG assisted with extracorporeal circulation. The number of bypass grafts was 1 to 4 (mean 3.2±1.1). Results There were more coexisting diseases in octogenarians underwent CABG. Fifteen patients were unstable angina pectoris and sixteen patients had a history of myocardial infarction. One patient died in postoperative period. The most frequent complication was atrial fibrillation (52.6%). Acute kidney injury (AKI) (31.6%), cardiac insufficiency (42.1%), chornic anemia (42.1%) and hypoproteinemia (47.4%) were observed at a higher incidence. Conclusions Because of critical preoperative state and with more comorbidity, careful preoperative evaluation and intensive perioperative treatment must be enhanced in octogenarians who underwent CABG. Frequency of postoperative follow-up can be properly increased. Key words: Aged, 80 years and over; Coronary artery disease; Coronary artery bypass grafting; Clinical analysis
