atheroma

 [ath″er-o´mah]
an abnormal mass of fatty or lipid material with a fibrous covering, existing as a discrete, raised plaque within the intima of an artery. adj., adj atherom´atous.

ath·er·o·ma

(ath'er-ō'mă),
The lipid deposits in the intima of arteries, producing a yellow swelling on the endothelial surface; a characteristic of atherosclerosis.
Synonym(s): atherosis

atheroma

(ăth′ə-rō′mə)
n. pl. athero·mas or athero·mata (-mə-tə)

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 

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

Surface lesion area and arterial vessel circumference were quantified using cellSens Standard 1.13 (Olympus software) to calculate percentage of atheroma lesion area normalized to arterial wall circumference (n of 4 per group).
Although non-vitamin-K oral anticoagulants have not been extensively studied for secondary ischemic stroke prevention in patients with an aortic atheroma >4 mm; our patient on follow-up did not have any subsequent cerebrovascular events or any episodes of major bleeding.
In agreement with these previous studies, we observed that soy milk was effective in reducing oxidative stress induced by hyperlipidic diet in aorta from LDLr-/- mice and, importantly, atheroma plaque area was three times smaller in [LDLr.sup.-/-] mice treated with soy milk than in the non-treated group.
The fibroatheroma type (Grade 5) was the most common type in our study (20.5%), next in frequency was atheroma (18.6%); however, Dhruva et al.
The results of the present study in elderly persons at high cardiovascular risk suggest that long-term adherence to a MeDiet could delay atheroma plaque development by reducing rolling, adhesion, and migration processes of circulatory mononuclear cells into the arterial wall.
As other calcifications can appear in the same region of atheroma on panoramic radiograph, which may be anatomic (hyoid bone, cartilage triticeous, epiglottis, etc.) or pathologic (calcified lymph nodes, tonsilloliths, phleboliths, etc.) (3), it is necessary another radiographic (AP) or exam for the diagnosis to be confirmed.
Hypertension occurs when the blood vessels constrict due to a permanent reduction in the cross-sectional area as a result of atheroma deposits, or a temporary narrowing due to an increase in hormonal production.
In the macroscopic phase, coronary dominance and the length of each vessel were determined; in the microscopic phase, the luminal diameter, wall thickness, amount of elastic fibers in the tunica media, and the presence of atheroma and its size were determined.
One patient with non-occlusive atheroma had changes in the recovery phase only.
TEE findings of atrial stasis, thrombosis and of aortic atheroma are independently associated with high thromboembolic risk in patients with AF.
The international team examined the association between drinking coffee and the presence of coronary artery calcium (CAC), an early indicator of coronary atherosclerosis - a potentially serious condition where arteries become clogged up by fatty substances known as plaques or atheroma. This can cause the arteries to harden and narrow, leading to blood clots which can trigger a heart attack or a stroke.
