Clinical analysis of off-pump coronary artery bypass grafting in CHD patients with their age ≥75 years / 中华老年心脑血管病杂志

ABSTRACT

Objective To analyze the clinical and perioperative data of off-pump coronary artery bypass grafting (OPCABG) in CHD patients with their age ≥75 years.Methods The ICU stay time,mechanical ventilation time,incidence of postoperative complications and mortality in 127 CHD patients with their age≥75 years who underwent OPCAB in our hospital were retrospectively analyzed.Results Of the 127 CHD patients,2 were transfered to extracorporeal circulation because it was difficult to maintain the intraoperative circulation,the remaining 125 (98.43％) underwent successful OPCABG.The mean number of grafted blood vessels was 2.44 ± 1.05,the postoperative mechanical ventilation time was 30.8±47.7 h,and the ICU stay time was 57.2±60.3 h.Perioperative myocardial infarction occurred in 6 patients,second operation was performed in 3 patients,postoperative renal failure was diagnosed in 1 patient,pulmonary complications were detected in 17 patients,death occurred in 4 patients (3.1％) after operation.Eighty-two patients (66.7％) were followed up for 28.3± 12.8 months.The postoperative 2-year survival rate was 95.9％.The incidence of postoperative MACCE was 8.5 ％.Conclusion OPCABG is safe and effective for CHD patients with their age ≥75 years and can thus be used as a routine procedure.
