    Coronary metabolic vasodilation ensures myocardial oxygen delivery aligns with cardiac contractile function during increased metabolic activity.

  • 2

    ATP-sensitive potassium channels (KATP) in cardiomyocytes play a crucial role in mediating coronary metabolic vasodilation.

  • 3

    Glibenclamide, a KATP channel blocker, is expected to inhibit coronary metabolic vasodilation by disrupting hyperpolarization and K+ accumulation.

  • 4

    The analysis of KATP channels should focus exclusively on metabolic stimuli like exercise, avoiding confounding factors from ischemia or hypoxia.

  • 5

    This meta-analysis aims to evaluate studies on KATP channels' role in coronary metabolic vasodilation during exercise.
