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 ...

Journal of Biomechanical Engineering, 1993
Dramatic advances have been made in the last two decades in the diagnosis and treatment of coronary artery disease. The development of open heart surgical techniques for bypassing occluded arteries made quantitative diagnostic techniques more important.

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 ...

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.

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.

Coronary Circulation and Interventional Cardiology
Annals of Biomedical Engineering, 2005Cardiovascular 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.

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.
