Summary: Background: Heart transplantation is the definitive treatment for many cardiovascular diseases. However, no ideal approach is established to evaluate heart grafts and it mostly relies on qualitative interpretation of surgeon based on the org

Background Both mitochondrial adenosine triphosphate-sensitive potassium (MKATP) channels (selectively blocked by 5-hydroxydecanoate) and stretch-activated channels (blocked by gadolinium) have been involved in the mechanism of ischemic preconditioni

ATP-dependent potassium ([Formula: see text]) channels play a role in the infarct size-limiting effect of preconditioning in pigs. We previously demonstrated that preconditioning shortens monophasic action potential duration (MAPD) and accelerates th

Preconditioning protects the rat heart from ventricular arrhythmias. However, the mechanism of this beneficial effect and its existence in large animal models remain unknown. We submitted 49 pigs to 40 min of left anterior descending coronary occlusi
