| | The coronary circulation in human septic shock. |
| | This pattern of disordered coronary autoregulation is analogous to the pattern of arteriovenous shunting in other organs in patients with septic shock. | | | These patients had coronary flow similar to or higher than that of control subjects and similar to that of the other three patients, who did not develop myocardial depression. | | | A proposed mechanism, based on animal studies, is myocardial ischemia resulting from inadequate coronary blood flow. |

| | The external pressure on the coronary circulation exerted by the force of contraction of the myocardium has an important influence on coronary resistance, especially in the left ventricular myocardium. | | | During diastole (0), when the ventricular myocardium is relaxed, coronary flow depends primarily upon the aortic pressure. | | | The "Other Organs" include all parts of systemic circulations not specifically listed in the table, e.g., blood flow through the bones, many endocrine glands, urogenital system, bronchial circulation, etc. Because of the differences in sizes of the different organs, blood flow and oxygen consumption are also expressed in terms of values per 100 gm weight. |

| | The coronary circulation is the vascular system that supplies the heart muscle with blood. | | | In a healthy heart, coronary blood flow is adapted to the metabolic needs of the heart muscle. | | | Based on physiological studies, a number of hypotheses has been formulated to explain the influence of heart contraction and local control mechanisms on coronary flow. |

| | CHEST: Effect of Pericardial Pressure on Human Coronary Circulation - ) |
| | Based on animal studies, previous authors have concluded that with an increase in pericardial pressure there is a continuous decline in coronary blood flow, with a reduction of approximately 50% during cardiac tamponade, but controversy exists about the underlying mechanism. | | | During that procedure, we calculated blood flow to the nondiseased left anterior descending coronary artery with increasing pericardial pressure achieved by the infusion of warmed normal saline solution at a rate of 30 mL/min. | | | These changes did not affect the coronary vasodilator reserve, which remained almost constant in each phase of the study. |

| | With the development of clinical diagnostic techniques to investigate the coronary circulation in conscious humans, the in vitro validation of such newly developed techniques is of major importance. | | | The pressure and flow signals obtained are similar to physiological human coronary pressure and flow, both for baseline and hyperaemic conditions. | | | The model allows for in vitro evaluation of clinical diagnostic techniques. |

| | coronary circulation -- Encyclopædia Britannica |
| | In the human heart, two coronary arteries arise from the aorta just beyond the semilunar valves; during diastole, the increased aortic pressure above the valves forces blood into the coronary arteries and thence into the musculature of the heart. | | | These act primarily by varying the heart's pulse rate, amplitude, or stroke volume and by altering the degree of dilation or constriction of the peripheral blood vessels... | | | Since the fetal lungs and digestive system are not yet functioning, these areas are bypassed by the fetal circulation. |

| | Role of Histamine in the Regulation of Coronary Circulation |
| | The aim of this study was to evaluate the role of endogenous histamine in the regulation of reactive hyperaemia (RH) and coronary autoregulation in isolated rat hearts. | | | During the first 15 s following 30 s of coronary occlusion, the release of histamine increased about three times and returned to basal levels after approximately 90 s, paralleling the changes of coronary flow (CF). | | | Blockade of histamine receptors decreased, while L-NAME significantly widened the autoregulatory range of the isolated rat heart, reduced CF and release of NO, but reversed the pattern of histamine release leaving the autoregulatory range unaltered, which indicate that endogenous histamine does not play a role in the regulation of coronary autoregulation. |
