Clinical analysis of off-pump coronary artery bypass grafting in elderly patients with diabetes mellitus / 中华老年医学杂志

ABSTRACT

Objective To conduct a clinical analysis of off-pump coronary artery bypass grafting (CABG)in elderly patients with diabetes mellitus.Methods Clinical data of 115 elderly patients with or without diabetes mellitus undergone off-pump CABG from January 2012 to June 2018 were retrospectively analyzed.The impact of diabetes mellitus on the prognosis in elderly patients undergone off-pump CABG was analyzed.Results Compared with elderly non-diabetic patients,the incidences of pulmonary infection,perioperative myocardial infarction,neurological complications,psychiatric symptoms,low cardiac output syndrome,rethoracotomy,respiratory failure,arrhythmia,postoperative 30-day mortality,blood transfusion volume,mechanical ventilation time,postoperative 24-hour drainage volume,the length of hospital stay and large doses of dopamine usage (＞10μg · kg-1 · min-1)increased lightly in elderly diabetic patients after off-pump CABG,but the difference had no statistical significance (all P ＞ 0.05).The incidences of postoperative renal insufficiency and incision complications were higher in elderly diabetic patients than in elderly nondiabetic patients(x2 =3.736、1.237,P =0.021、0.037).Conclusions Off-pump CABG is safe and effective for elderly diabetic patients if their blood glucose levels are controlled reasonably well.
