Abstract:
Objective To compare the myocardial protective effects of Del nido cardioplegia(DC)and microplegia(MP)in the isolated coronary artery bypass grafting(CABG)underwent the cardiopulmonary by-pass(CPB),and evaluate the safety and efficacy of DC in isolated CABG.Methods A retrospective analysis was performed on 128 patients with isolated CABG by the same surgical team form January 2018 to April 2021 at the Second Affiliated Hospital of Army Medical University.The patients were divided into MP group(n=57)and DC group(n=71)according to the use of intraoperative cardioplegia during the surgery.Preoper-ative baseline data,blood gas at 4 time points of CPB 20 min(T1),CPB 60 min(T2),end of CPB(T3),and re-turning of ICU(T4),as well as perioperative data,major postoperative complications,mortality,medium and long-terms survival rate were collected.Results Compared with preoperative baseline data,the lactate(Lac)level in the DC group was lower;During the operation,the DC group had fewer times of cardiac arrest fluid perfusion and a larger amount volume of cardioplegia(P<0.001);In CPB,there was a higher fluid balance and a higher rate of spontaneous rebeating(88.7%vs.52.6%),differences were statistically significant(P<0.05).Blood gas at all 4 time points showed that the DC group had lower blood glucose level(P<0.05).The cardiac troponin Ⅰ(cTnⅠ)concentration 24 h postoperative was higher(P<0.05),and the ICU duration was shorter(P<0.05).Correlation analysis indicated that there was no correlation between cTnⅠ concentration 24 h postoperative and aortic cross clamping time(ACCT)in both groups(P>0.05).There was a positive correlation between the concentration of cTnⅠ 24 h postoperative and the numbers of cardioplegia deliveries(r=0.331,P=0.005)in DC group,but there was no correlation in MP group(r=0.023,P=0.866).There was no significant difference in perioperative period,postoperative complications and mortality between the two group(P>0.05).Kaplan-Meier analysis showed that there was no statistically significant difference in the 5 years survival rate between two groups(P=0.966).Conclusion Compared with MP,DC provides a comparable myocardial protection effect in the isolated CABG,with higher security,without affecting the short and medium-term clinical outcomes in patients.
