A variety of preclinical and clinical studies using different cell types have demonstrated variable degrees of improvement in cardiac function in models of acute myocardial infarction (MI ...

Intracellular calcium within the cardiac myocytes is increased by digoxin, resulting in increased inotropy, or contractility. Digoxin toxicity causes hyperkalemia, or high potassium. The sodium ...

The enzymes troponin I and troponin T are normal proteins that are important in the contractile apparatus of the cardiac myocyte. The proteins are released into the circulation between 3 and 4 ...
