But we must include another element--spasm of the coronary vessels.
When this sudden systemic arteriole spasm extends to the coronary vessels in a heart whose walls are diseased, a fatal attack of angina with the heart full of blood may be induced.
The essential difference lies in the fact that pseudo-angina is independent of structural disease of the heart and coronary arteries.
She had aortic valve stenosis, well along, the same condition that had precipitated the coronary destruction that took Camille from him.
They were marketed together with stents, miniature metal mesh supports that keep coronary arteries open after angioplasty.

The most common source of this embarrassment is perhaps failure of nutrition in the muscular walls of the heart, from disease of the coronary arteries.
It is very probable that his coronary arteries have now become involved in the degenerative process.
I have myself known a first attack prove fatal in the course of an hour; there was very considerable ossification of the coronary arteries and fatty degeneration of the heart-walls.
Thirdly, the organic changes most frequently met with have been fatty atrophy and flabby dilatation of the heart; obstructive disease of the coronary arteries by atheroma and calcification of the orifice and arch of the aorta.
Valvular diseases and narrowing of the coronary arteries in angina).
Just how the cardiac nutrition is to be improved without an improved coronary circulation is not explained.
It would be interesting to know in what other way this is to be accomplished, and how an improvedcoronary circulation can be induced without acting on the heart or vessels.
Footnote: The coronary artery, springing from the aorta just after its origin, carries blood to the muscular walls of the heart; the venous blood comes back through the coronary veins, and empties directly into the right auricle.
Now this place is the heart, for it alone of all the parts contains blood for the public use in its cavities, the auricles and ventricles, as in cisterns and storehouse; not merely blood for its private use in the coronary vein and artery.
Besides, if the blood could permeate the substance of the septum, or could be imbibed from the ventricles, what use were there for the coronary artery and vain, branches of which proceed to the septum itself, to supply it with nourishment?
The coronary sinus is a short venous trunk a little over an inch in length, which occupies the right half of that portion of the auriclo-ventricular groove which lies between the left auricle and ventricle.
It is the result of a rupture of an aneurism of the aorta or coronary arteries, or in rare cases from rupture of the heart.

If for any reason the heart does not get this proper nourishment, say the coronary arteries should become clogged, or a fatty infiltration, or a lack of red blood corpuscles, we would have a condition in the body known as anemia.
Gray)] Beginning in the tissues of the heart are the coronary veins, which terminate in the coronary sinus and then into the right auricle of the heart through the coronary valves.
It has five ligaments, right and left lateral or triangular, falciform, coronary and round.
The branches of the coronary arteries upon the surface of the heart are, as a rule, all end arteries; that is, arteries which form no direct anastomosis with their neighbors.
The heart receives its blood supply through the two coronary arteries which arise from the aorta immediately above its origin, the return flow being by the coronary veins which open into the right auricle of the heart by the coronary sinus.
The heart receives its blood supply from the coronary arteries, which are branches of the ascending aorta, just after it leaves the aortic semi-lunar valve.
The coronary veins bring the venous blood back from the tissues of the heart and empty into the coronary sinus, back of the right auricle of the heart.
Here the two coronary arteries come off which go to supply the muscular tissues of the heart.
The superior and inferior venae cavae empty into the right auricle of the heart, also the blood from the coronary sinus.
In the floor of the ulcer, which extended to the muscular coat, was a small perforated aneurism of a branch of the coronary artery.
Further communication between the portal and the veins of the diaphragm takes place by means of the veins in the coronary and suspensory ligaments.
In one case Powell[90] found a small aneurism of the coronary artery in an ulcer of the lesser curvature of the stomach.
The area of direct diaphragmatic attachment is narrow and consequently the two layers of the coronary ligament are close together at this point.
The stomach is removed, dividing of course the coronaryartery and vein and the left gastro-epiploic artery.
The coronary artery, like the splenic, is at first situated between the layers of the dorsal mesogastrium (vertebro-splenic segment).
Begin with the caudal layer of the coronaryligament on the extreme right, where fusion with the corresponding cephalic layer produces the right triangular ligament.
Like the splenic the coronary artery becomes anchored to the abdominal background and placed secondarily behind the parietal peritoneum of the lesser sac by the adhesion of this mesogastric segment to the primitive parietal peritoneum.
As the vein develops the interval between the two layers of the rightcoronary ligament increases, producing the well-known large non-peritoneal area on the dorsal surface of the adult liver, which is directly attached to the diaphragm.
Dorsal: Parietal peritoneum, reflected along the line CD, from the caudal layer of the coronary ligament to the diaphragm.
A similar fold, further to the left, carries in a like manner the coronary artery of the stomach to the cardiac end of the lesser curvature.
The dorsal surface of the right lobe to the right of the postcava is peritoneal, there being no extension laterad of the right coronary and triangular ligaments.

It extends but a short distance into the tissues, yet destroys the patient by separating the hoof from the coronary band, upon which it depends for support and growth.
Suppuration of the sensitive sole is more common than of the sensitive laminæ and coronary band.
The pus collects at the point of injury and finally escapes by working its way between the sensitive and insensible laminæ to the top of the hoof, where an opening is made between the wall and coronary band at or near the heels.
When the injury is deep, followed by inflammation and suppuration of the coronary band, lateral cartilages, sensitive laminæ, etc.
To do this a double sage-knife is run flatwise between the coronary cushion and the cartilage, with the convex surface of the blade towards the skin.

In the lateral and anterior regions of the coronary edge the contraction disappears; and when the weight is thrown off the foot it passes into a gentle expansion of the coronary edge of the toe.
This last distinction we make ourselves, and, referring to cracks of the wall, term them high when commencing from the coronary margin, low when starting from the bearing surface.
The presence of fat in various organs of the body in pernicious anæmia, and in the heart in connection with stenosis of the coronary artery, is universally recognized.
Embolism of thecoronary arteries is rare, while embolism of the splenic artery, the left renal and left iliac arteries, is comparatively common, and in the order mentioned.
Hemiplegia, or perhaps aphasia or other evidence of localized disturbance, follows central embolism; angina pectoris, with a disturbed cardiac action, results from embolism of the coronary artery.

There was a medical report that Wood had undergone a mild coronary occlusion some months ago which had hastened his retirement.
I wondered whether his retirement had been hastened by a real coronary occlusion or whether he'd used his extra-sensory power to fake the symptoms and control the doctor's instruments.
I clamped your coronary artery shut for a few seconds.
This prolonged rest or diastole of the heart allows the circulation in the coronary arteries to become normal, and the nutrition and muscle tone of the heart improves.
Unless the left ventricle can do its work well enough to maintain an adequate pressure of blood in the aorta, the coronary circulation is insufficient, and chronic myocarditis is the result.
Digitalis should not be used when there is fatty degeneration of the heart; it should ordinarily not be used when there is arteriosclerosis, and very rarely, if ever, when it is decided that there is coronary disease.

The disease is often caused by a narrowing or obstruction or calcareous degeneration of the coronary arteries, thus diminishing the blood supply to the heart muscle.
Not infrequently in sclerosis of the arteries, especially of the coronary arteries, the blood pressure is not high, but low, and the heart is insufficient.
A patient with coronarydisease should certainly not go to any great altitude, while patients with compensated valvular lesions, he found, were not injured by ordinary heights.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "coronary" in a variety of sentences. We hope that you will now be able to make sentences using this word.
