Coronary Circulation, its Physiological Aspect

The physiological explanation of the changes in the coronary circulation precipitated by aortic-coronary sinus anastomosis.

Coronary Circulation

T he effects of hypertension and hypertrophy on the coronary circulation are subjects of increasing investigative interest.1-3 Animal studies have shown that the major conduit arteries are enlarged in pressure-overloaded, hypertrophied ventricles, but this increase falls short of paralleling the extent of hypertrophy.4 This enlargement is accompanied by an increase in the extracellular componen...

Wave intensity analysis and its application to the coronary circulation

Wave intensity analysis (WIA) is a technique developed from the field of gas dynamics that is now being applied to assess cardiovascular physiology. It allows quantification of the forces acting to alter flow and pressure within a fluid system, and as such it is highly insightful in ascribing cause to dynamic blood pressure or velocity changes. When co-incident waves arrive at the same spatial ...

Coronary Circulation After Coronary Spasm

To examine whether acute myocardial ischemia activates the coagulation system and platelet activation in the coronary circulation, we measured plasma levels of fibrinopeptide A and j3-thromboglobulin in the coronary sinus and the aortic root simultaneously in 15 patients with coronary spastic angina before and after the left coronary spasm induced by intracoronary injection of acetylcholine and...

Pathophysiology of coronary circulation.

I consider it a great honour to have been asked to give the Sir Thomas Lewis Lecture, and I have chosen for my subject the pathophysi,,ology of the coronary circulation a topic which was of great interest to Sir Thomas. Another reason for selecting this topic is that so much of the good, recent work in this field * has been done in Britain and many of the investigators who have made significant...
