Prostaglandins (PG's) fulfil most of the criteria required for the metabolic 'coupler' linking increases in myocardial activity with increases in coronary blood flow. They are synthesized by the heart and coronary vessels, profoundly modify coronary blood flow in low concentrations and are released under conditions of hypoxia and myocardial ischaemia. Studies with inhibitors of PG-synthetase however provide no firm evidence that PG's are involved in the physiological regulation of myocardial blood flow. These studies are reviewed.
