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.

The Coronary Collateral Circulation
Annals of Internal Medicine, 1972Excerpt The widespread use of coronary arteriography and revascularization surgery has stimulated interest in the coronary collateral circulation.

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 ...

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

Autoregulation of the coronary circulation
Progress in Cardiovascular Diseases, 1987Coronary autoregulation appears to be closely coupled to myocardial oxidative metabolism. Recent data suggest that coronary autoregulation depends on the prevailing balance between myocardial oxygen supply and demand. It seems likely that pO2 within a critical range may be the initial metabolic stimulus for coronary autoregulation.

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.

The dynamics of the coronary collateral circulation
Nature Reviews Cardiology, 2014Coronary collaterals are present at birth, with wide interindividual variation in their functional capacity. These vessels protect jeopardized myocardium, and the number of collaterals and the extent of their coverage are associated with improved survival in patients with coronary heart disease.
