Abstract
AbstractObjectivesTo compare the safety and efficacy of del-Nido cardioplegia (DNC) with traditional 4:1 cold blood cardioplegia (CBC) in coronary artery bypass grafting and/or valve surgeries in elderly patients.MethodsThe present study is a retrospective case-series study that included 302 consecutive patients aged 70 years and over who underwent on-pump valve surgery and/or coronary artery bypass graft (CABG). DNC was administered to 90 patients and CBC to 212 patients. After propensity-score matching, 89 pairs were compared. The safety and efficacy were analyzed between the two groups.ResultsThe DNC group had a similar mortality (3.4% vs. 5.6%, OR = 0.79,P = 0.720) and extracorporeal membrane oxygenation (ECMO) implantation rate (1.1% vs. 2.2%, OR = 0.75,P = 1.000) to the CBC group, a lower incidence of postoperative intra-aortic balloon pump (IABP) implantation (1.1% vs. 9.0%, OR = 0.54,P = 0.034) and a higher left ventricular ejection fraction (LVEF) at discharge (60 (56–64) % vs. 57 (51–62)%,P = 0.007). The estimated glomerular filtration rate (eGFR) in the DNC group was higher when the patient was transferred to the intensive care unit (79.4 (65.0-94.3) ml/min/1.73m2vs. 77.2 (59.8–88.7) ml/min/1.73m2,P = 0.014), but no significant differences were identified after 24 h. The serum lactate values of the DNC group were significantly lower than those of the CBC group (0 h: 2.7 (2.0-3.2) vs. 3.2 (2.4–4.4),P = 0.001; 3 h: 3.2 (2.0-4.8) vs. 4.8 (2.8–6.6),P < 0.001; 6 h: 3.5 (2.2–5.4) vs. 5.8 (3.4–8.4),P < 0.001; 9 h: 3.4 (2.0–7.0) vs. 5.5 (2.9–8.3),P = 0.005). There were no differences between the two groups in respect of lactate levels at 12 h and thereafter. Postoperative creatinine kinase-MB concentrations were similar between the two groups.ConclusionsDel-Nido cardioplegia is safe and effective in elderly patients undergoing CABG and/or valve surgery.
