The human coronary collateral circulation: development and clinical importance.
Coronary collaterals are an alternative source of blood supply to myocardium jeopardized by ischaemia. In comparison with other species, the human coronary collateral circulation is very well developed. Among individuals without coronary artery disease (CAD), there are preformed collateral arteries preventing myocardial ischaemia during a brief vascular occlusion in 20-25%. Determinants of such...
متن کاملThe human coronary collateral circulation.
BACKGROUND Coronary collaterals are an alternative source of blood supply to myocardium jeopardized by ischaemia. Well-developed coronary collateral arteries in patients with coronary artery disease (CAD) mitigate myocardial infarcts and improve survival. METHODS AND RESULTS Collateral arteries preventing myocardial ischaemia during brief vascular occlusion are present in 1/3 of patients with...

متن کاملVasopressin and the mature coronary collateral circulation.
In isolated vascular rings, we have shown that mature coronary collateral vessels are highly responsive to the vasoconstrictor effects of vasopressin. The purpose of the present study was to determine the effect of concentrations of vasopressin encountered in pathophysiologic states on the collateral circulation in vivo. We studied eight open-chest anesthetized dogs with mature coronary collate...
متن کاملCoronary arterial spasm and collateral circulation.
Coronary arteriographic studies were performed on a 52year-old man because of severe progressive angina. First, contrast material was injected into the night coronary artery and showed 100 percent obstruction in its middle portion. Then injection into the left coronary artery revealed subtotal obstruction of the left anterior descending coronary artery and of the obtuse marginal branch of the c...
