ATHEROMA

Angiographic intervention Trial using HMG CoA reductase inhibitor to Evaluate Retardation of Obstructive Multiple Atheroma. A trial comparing changes in coronary atheromas with pravastatin vs diet in patients with CHD.
Conclusion Pravastatin 10–20 mg/day for 3 years improves hyperlipidaemia, then suppresses progression and induces regression of focal coronary atherosclerosis in Japanese coronary artery disease patients with raised serum cholesterol.

ath·er·o·ma

(ath'ĕr-ō'mă)
The lipid deposits in the intima of arteries, producing a yellow swelling on the endothelial surface; a characteristic of atherosclerosis.
[G. athērē, gruel, + -ōma, tumor]

atheroma

The material containing CHOLESTEROL, degenerate muscle cells, blood clot, blood PLATELETS and fibrous tissue, which forms on the inner surface of arteries in the disease of ATHEROSCLEROSIS and which promotes THROMBOSIS and obstruction to the blood flow. From the Greek athara , gruel or porridge, and oma , a lump.

atheroma

degeneration of the inner lining of an artery, caused by the formation of fatty plaques and scar tissue.

atheroma

endproduct of chronic intravascular inflammation and repair, initiated by endothelial injury (e.g. shear stress secondary to hypertension) and leading to lipid deposition and formation of yellow, fatty streaks, characteristic of atherosclerosis

atheroma 

Fatty deposits which lead to the formation of plaques in the blood vessels. See arteriosclerosis; Hollen-horst's plaques.
