U.S., Nov. 26 -- ClinicalTrials.gov registry received information related to the study (NCT07249424) titled 'Effective Myocardial Protection Time of Del Nido Cardioplegia in Adult Cardiac Surgery' on Nov. 18.
Brief Summary: This is a single-center, prospective, observational cohort study designed to quantify the effective myocardial protection window of Del Nido cardioplegia during adult open-heart surgery performed under cardiopulmonary bypass (CPB) and aortic cross-clamp (ACC). Without altering routine care, the study will obtain time-stamped high-sensitivity cardiac troponin (hs-cTn) measurements at predefined intraoperative and early postoperative intervals to identify the inflection ("change-point") at which biochemical evidence of is...
