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.

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.

Endothelium Dysfunction in the Coronary Circulation
Journal of Cardiovascular Pharmacology, 1994Coronary artery disease is the most important cause of morbidity and mortality in Western countries. Its pathogenesis is unknown but involves an enhanced vasoconstriction and increased interaction of platelets and monocytes with the vessel wall, as well as proliferation, migration, and extracellular matrix formation of vascular smooth-muscle cells. The

The Coronary Circulation in Cardiac Hypertrophy
Journal of Cardiovascular Pharmacology, 1993Left ventricular hypertrophy is a common and important risk factor for cardiac mortality and morbidity. Cardiac hypertrophy adversely affects coronary perfusion because hypertension, its most frequent cause, is a major risk factor for coronary disease, and because cardiac hypertrophy may be associated with myocardial ischemia even in the absence of ...

Control of the Coronary Circulation
1984Normal function of the heart depends on an adequate coronary blood flow. Myocardial metabolism and coronary flow are mutually interactive so that any increase in the metabolism of the normal heart is matched by an increase in coronary blood flow, and any significant restriction of flow in pathophysiologic states results in the reduction of myocardial ...

An appreciation of the coronary circulation not only leads to more appropriate management of patients undergoing surgical procedures directly related to coronary artery disease, but is also required because of undiagnosed disease in patients otherwise presumed healthy.
