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
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 ...

Experimental ligation of the coronary arteries 1 and observations on man following the occlusion of these vessels 2 have demonstrated that the heart is extremely sensitive to a reduction in its blood supply. It would seem that a knowledge of the factors concerned in the regulation of the coronary circulation is important for a better understanding of ...

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.

Cardiopulmonary receptors and coronary circulation
Journal of the Autonomic Nervous System, 1990Coronary blood flow has long been regarded as being regulated primarily by the metabolic demand of the myocardium [1,2]. Experimental and clinical reports [3-9], however, indicate that such coronary regulation can be overridden by the adrenergic drive to the heart.
