Application

Pinacidil monohydrate has been used:
  • in repolarization studies by infusing into left anterior descending artery (LAD)
  • to induce ATP-sensitive K+ (KATP) current in ventricular myocytes for electrophysiological studies
  • as a KATP opener to treat myocardial cells

Biochem/physiol Actions

K+ channel activator; antihypertensive.
Pinacidil is a KATP channel agonist. It protects cardiomyocytes by preventing loss of mitochondrial membrane potential. It prevents the caspase 3 activation in hypoxia/reoxygenation injury.

Background: The detection and localization of electrophysiological substrates currently involve invasive cardiac mapping. Electrocardiographic imaging (ECGI) using the equivalent dipole layer (EDL) method allows the noninvasive estimation of endocardial and epicardial activation and repolarization times (AT and RT), but the
