Possible mechanisms responsible for silent myocardial ischemia: do patients with silent myocardial ischemia have altered pain thresholds?
There is some evidence that alterations in pain perception are present in patients with coronary artery disease and painless myocardial ischemia, but whether endorphins are implicated is still unclear. Further studies are also needed to document the validity of various theories of the cardiac pain mechanism itself, especially the existence of specific nociceptive sympathetic fibers.
