As this book deals with the relationship between coronary pressure and myocardial blood flow, some basic anatomic and physiological concepts should be well understood. This chapter does not claim to be an extensive review of the physiology of the coronary circulation but aims at providing the reader with the anatomic and physiologic background required

CORONARY COLLATERAL CIRCULATION
American Journal of Roentgenology, 1973In the presence of obstructing coronary atherosclerosis, collateral circulation may develop through pre-existing anastomotic channels which are present, though nonfunctional, in normal hearts. These anastomoses connect various branches of the same coronary artery or different coronary arteries.

Isradipine and the coronary circulation
Acta Anaesthesiologica Scandinavica, 1993Isradipine has been shown to be an effective vasodilator in different vascular beds. Experimental evidence suggests that isradipine is a potent coronary vasodilator, and this is supported by clinical studies in both cardiology and cardiac surgery. Furthermore, in these studies, coronary vasodilatation was not accompanied by evidence of any significant ...

Coronary Collateral Circulation
Chest, 1974Collateral coronary channels represent obvious compensatory mechanisms for the delivery of nutrients to the myocardium. In spite of extensive basic research, we are still unaware of the factors determining adequate compensatory adjustments. Extensive human pathologic studies have presented a quantitative overall view, but have said little about the ...

Pharmacology of the Coronary Circulation
Annual Review of Pharmacology, 1972The literature in the past year or two has given ample evidence that the investigation of the coronary vasculature is p rogress ing rapidly from a very rudimentary level to a much more sophisticated one both in theo ry and ap plied methods. It is also evident, however, that the goal of understanding the molecular events comprising the nutritional ...

The relations between arterial pressure and flow in the coronary bed are under the influence of the humoral-nervous systems, and under local control, i.e., autoregulation. There is also the mechanical effect of the contracting cardiac muscle on coronary flow.

Coronary Circulation and Interventional Cardiology [PDF]
Annals of Biomedical Engineering, 2005 Cardiovascular disease has long been the leading cause of death in developed countries and it is rapidly becoming the number one killer in developing countries. Sudden heart attacks remain the primary cause of death in the United States: over 1.4 million attacks are suffered every year, more than half of which prove fatal.

An Appreciation of the Coronary Circulation
Anesthesia & Analgesia, 1986Coronary sinus catheter techniques for evaluation of coronary flow and myocardial metabolism have the drawback that a global sampling method is used to evaluate a regional disease (coronary artery disease). Studies on the coronary circulation are further limited by the fact that interventions acting on the coronary bed may simultaneously modify several

Heterogeneity in the Coronary Circulation
Journal of Cardiovascular Pharmacology, 1985The blood flow to the subendocardial layers of the left ventricle is approximately 10% higher than that to the outer layers. The larger subendocardial blood flow reserve results from a higher vascular density within that layer. The systolic coronary inflow is the result of the net forward flow and a concealed backflow.
