insufficiency

 [in″sŭ-fish´en-se]
inability to perform properly an allotted function; called also incompetence.
adrenal insufficiency abnormally diminished activity of the adrenal gland; called also hypoadrenalism.
adrenocortical insufficiency abnormally diminished secretion of corticosteroids by the adrenal cortex; see also addison's disease. Called also hypoadrenocorticism and hypocorticism.
aortic insufficiency inadequate closure of the aortic valve, permitting aortic regurgitation.
coronary insufficiency decreased supply of blood to the myocardium resulting from constriction or obstruction of the coronary arteries, but not accompanied by necrosis of the myocardial cells. Called also myocardial ischemia.
ileocecal insufficiency inability of the ileocecal valve to prevent backflow of contents from the cecum into the ileum.
mitral insufficiency inadequate closure of the mitral valve, permitting mitral regurgitation.
placental insufficiency dysfunction of the placenta, with reduction in the area of exchange of nutrients; it often leads to fetal growth retardation.
pulmonary valve insufficiency inadequate closure of the pulmonary valve, permitting pulmonic regurgitation.
respiratory insufficiency see respiratory insufficiency.
thyroid insufficiency hypothyroidism.
tricuspid insufficiency incomplete closure of the tricuspid valve, resulting in tricuspid regurgitation.
valvular insufficiency failure of a cardiac valve to close perfectly, causing valvular regurgitation; see also aortic, mitral, pulmonary, and tricuspid insufficiency.
velopharyngeal insufficiency inadequate velopharyngeal closure, due to a condition such as cleft palate or muscular dysfunction, resulting in defective speech.
venous insufficiency inadequacy of the venous valves and impairment of venous return from the lower limbs (venous stasis), often with edema and sometimes with stasis ulcers at the ankle.

cor·o·nar·y in·suf·fi·cien·cy

inadequate coronary circulation leading to anginal pain.
Synonym(s): coronarism (1)

cor·o·nar·y in·suf·fi·cien·cy

(kōr'ŏ-nār-ē in'sŭ-fish'ĕn-sē)
Inadequate coronary circulation leading to anginal pain.

coronary insufficiency

A reduction in the coronary blood flow of such degree as to limit the full action of the heart muscle on demand. Coronary insufficiency commonly causes ANGINA PECTORIS.

insufficiency

inability to perform properly an allotted function.

adrenal insufficiency
hypoadrenalism.
aortic insufficiency
inadequacy of the aortic valve, permitting blood to flow back into the left ventricle of the heart.
cardiac insufficiency
inability of the heart to perform its function properly; heart failure.
coronary insufficiency
decreased supply of blood to the myocardium resulting from constriction or obstruction of the coronary arteries, but not accompanied by necrosis of the myocardial cells. Called also ischemic myocardial necrosis.
hepatic insufficiency
inadequate liver function, short of hepatic failure.
ileocecal insufficiency
inability of the ileocecal valve to prevent backflow of contents from the cecum into the ileum.
pulmonary insufficiency
insufficiency of the pulmonary valve, permitting blood to flow into the right ventricle of the heart.
respiratory insufficiency
a condition in which respiratory function is inadequate to meet the body's needs when increased physical activity places extra demands on it. See also respiratory insufficiency.
thyroid insufficiency
hypothyroidism.
valvular insufficiency
failure of a cardiac valve to close perfectly, causing the blood to flow back through the orifice (valvular regurgitation); named, according to the valve affected, aortic, mitral, pulmonary or tricuspid insufficiency.
velopharyngeal insufficiency
failure of velopharyngeal closure due to cleft palate, muscular dysfunction, etc., resulting in defective swallowing with regurgitation through the nose.
venous insufficiency
inadequacy of the venous valves with impairment of venous drainage, resulting in edema.

The drug, a powerful vasoconstrictor, is contraindicated in patients with hypertension or coronary insufficiency, and therefore cannot be used in cases of preeclampsia.
If the angina worsens or acute coronary insufficiency develops, restart BYSTOLIC promptly, at least temporarily.
COMBIVENT should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
