Does not support changing cardioplegia in cardiac surgery; leaves open translation of polarized arrest benefits to clinical outcomes.
Does hyperpolarized or polarized arrest improve myocardial protection compared to hyperkalemic cardioplegia during heart surgery or transplantation?
Hyperpolarized or polarized arrest may offer superior myocardial protection during cardiac surgery compared to traditional hyperkalemic cardioplegia by minimizing transmembrane fluxes and metabolic demand.
