The Novel St Thomas’ Hospital Polarizing Blood Cardioplegia: Results in Hearts With Reduced Ejection Fraction

This study investigates the efficacy of a new St Thomas’ Hospital polarizing cardioplegia (STH-pol) versus standard depolarizing cardioplegia (STH-control) in rats with chronic myocardial infarction. Although STH-pol showed trends toward better coronary flow and reduced myocardial oxygen consumption, no statistically significant difference in myocardial protection was found. Both solutions demonstrated comparable recovery and energy preservation.
