coronary
[kôr′əner′ē]
Etymology: L, corona, crown
1 adj, pertaining to encircling structures, such as the coronary arteries.
2 adj, pertaining to the heart.
3 n,
Usage notes: nontechnical.
a myocardial infarction or occlusion. coronary
encircling in the manner of a crown.
1. a term applied to vessels, ligaments, nerves, the band at the skin-hoof junction.
2. blood vessels partially encircling the heart.
coronary arteries
two large arteries that branch from the ascending aorta and supply all of the heart muscle with blood. See also Table 9.
coronary artery anomaly
one or both arteries originate from the pulmonary artery instead of the aorta; anoxia of the myocardium leads to congestive heart failure.
coronary artery laceration
in foals during a difficult parturition and in cattle due to penetration by a reticular foreign body; sudden death due to cardiac tamponade.
coronary artery rupture
can result from perforation by a foreign body from the reticulum as part of the syndrome of traumatic reticular pericarditis. Cardiac tamponade results, causing acute or congestive heart failure.
coronary band
the junction of the skin and the horn of the hoof.
coronary chemoreflex
intravenous injection of chemicals such as veratridine causes cardiac slowing, hypotension and apnea due to reflex response by the myocardium. Called also Bezold-Jarisch reflex.
coronary cushion
the spongy, resilient hypodermis beneath the coronary corium of the hoof.
coronary emboli
lodgment of an embolus in a coronary artery is a rare occurrence in animals. Myocardial ischemia and asthenia result, the effect on the animal varying with the amount of muscle compromised.
coronary occlusion
the occlusion, or closing off, of a coronary artery. The occlusion may result from formation of a clot (thrombosis). Narrowing of the lumen of the blood vessels by the plaques of atherosclerosis, as occurs in humans, does not occur in animals. If there is adequate collateral circulation to the heart muscle at the time of the occlusion, there may be little or no damage to the myocardial cells. When occlusion is complete, however, with no blood being supplied to an area of the myocardium, myocardial infarction results.
coronary perfusion pressure
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
coronary thrombosis
formation of a clot in a coronary artery. See also myocardial infarction.
coronary
adjective Referring to the blood vessels, nerves, and ligaments related of the myocardium noun A popular term for an acute MI. See Café coronary, Coital coronary.
