Popis: Background There has been increasing interest in using del Nido cardioplegia in adult cardiac surgery. However, there is limited evidence for its efficacy in patients with acute coronary syndrome and reduced ejection fraction. Methods This study examined patients with decreased ejection fraction (EF < 40%) who were hospitalized due to acute coronary syndrome and received either del Nido (DN) or cold blood cardioplegia (CB). The patients were matched based on age, gender, myocardial infarction at baseline, and number of conducted surgical procedures. An analysis was conducted on postoperative biomarker release (high-sensitivity troponin T and isoenzyme creatine kinase-MB (CK-MB)), changes in myocardial contractility and perioperative outcomes. Results 62 pairs of patients with similar baseline characteristics were selected. 51.6% of pairs underwent isolated coronary artery bypass grafting, while 48.4% underwent a complex procedure. Postoperative troponin values did not differ significantly at 12 h (median (IQR): 606.7 (381.4–974.8) pg/mL vs. 552 (231.8–1579.5) pg/mL; p = 0.913), nor did CK-MB (median (IQR): 24.3 (12.6–45.5) ng/mL vs. 23.7 (12.3–49.8) ng/mL; p = 0.972). The postoperative EF was similar between groups (median (IQR): 30% (30–35%) vs. 34% (30–38%); p = 0.323). No difference in perioperative mortality, myocardial infarction, stroke, or composite endpoint was noted. In a multivariate analysis, the cardioplegia protocol did not affect biomarker release or changes in ejection fraction. The first stage of acute kidney injury was more frequent in the CB group (28.5% vs. 9.7%, p = 0.033). Conclusions Both del Nido and cold blood cardioplegia provide adequate cardioprotection in patients with acute coronary syndrome with decreased ejection fraction.
