The 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 کاملRecent insights into coronary collateral circulation.
The functional significance of coronary collaterals in humans has been debated for many years. Correlations have now been made between the anatomic appearance of coronary collateral vessels visualized at the time of intracoronary thrombolytic therapy during the acute phase of myocardial infarction and the creatine kinase time--activity curve, infarct size, and aneurysm formation. These studies ...
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...
