Abstract
There is substantial evidence indicating that endogenous opioid peptides are involved in the pathophysiology of myocardial ischemia and reperfusion. We measured the myocardial and peripheral concentrations of beta-endorphin before and following myocardial ischemia and reperfusion during coronary angioplasty. The results indicate that in patients with coronary artery disease, there was an augmented myocardial concentration of beta-endorphin. Moreover, there was an increased peripheral concentration of beta-endorphin following myocardial ischemia and reperfusion. The data support the previous notion that endogenous opioid peptides are involved in the pathophysiology of ischemic heart disease.
