Myocardial energy balance and metabolism as causes of myocardial ischemia.

ABSTRACT

The current approach to myocardial ischemia has been influenced by the misconception of a close link between ischemia and coronary atherosclerotic obstructions. Recent guidelines have, however, acknowledged the multifactorial nature of this condition, with an identifiable cause present in less than half of angina patients, and a large fraction with angina of unknown origin. Because of this background, focusing on cardiac energy metabolim offers new opportunities to manage myocardial ischemia even when its cause is unknown.
