The effect of norepinephrine infusion on the coronary circulation has been studied in 21 subjects. In doses ranging from 2 to 17 µg. base per minute norepinephrine caused a pari passu rise in ...

Coronary blood flow was measured by the nitrous oxide method, and cardiac output was measured by the Fick principle, in a series of 31 human subjects with the clinical diagnosis of angina pectoris.

The coronary circulation originating from a single coronary ostium is rare. All possible anatomical variations were the basis of a recent classification. This case report describes a previously ...

CFR is a well-established, prognostically validated measure of the vasodilator capacity of the coronary circulation, combining both epicardial and microvascular resistance. CFR may be estimated ...

Conventional stress testing can overlook coronary vasospasm, a functional disorder of the coronary circulation, typically triggered by cold air or emotional stress rather than physical exertion (often ...

What are the coronary arteries? Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood ...
