Sevoflurane Suppresses Cardiomyocyte Pyroptosis in Myocardial Ischemia via NLRP3 Inflammasome Signaling.

ABSTRACT: The purpose of this study was to investigate the impact of sevoflurane (SEV) on cardiomyocyte (CM) pyroptosis following myocardial ischemia (MI). Reverse validation was performed by pharmacologically activating NLRP3 with monosodium urate (MSU) to confirm that SEV's cardioprotective effects were specifically mediated through the NLRP3 inflammasome pathway. Sprague Dawley rats were randomly assigned to sham (sham), model (conventional anesthesia + MI-reperfusion [MIR] injury modeling), SEV (SEV inhalation anesthesia + MIR injury modeling), and SEV + NLRP3 (SEV inhalation anesthesia + MIR injury modeling + NLRP3) groups. The myocardial area at risk (MAAR) and the myocardial infarct size (MIS) were evaluated in each experimental group, and cardiac tissue was examined using hematoxylin-eosin (
