It is caused by atherosclerosis, an accumulation of fatty materials on the inner linings of arteries. The resulting blockage restricts blood flow to the heart. When the blood flow is completely cut off, the result is a heart attack. It is sometimes also called coronary heart disease (CHD), but although CAD is the most common cause of CHD, it is not the only cause.;Atherosclerosis Overview;Developmental process of atherosclerosis ;The development of arterial atherosclerosis may occur when deposits of cholesterol and plaque accumulate at a tear in the inner lining of an artery. As the deposits harden and occlude the arterial lumen, blood flow to distant tissues decreases and a clot may become lodged, completely blocking the artery. ;屯葡凋搬剧志互垂猛煌注伯捂扎恍糜另溪皿兼冕旺钢萄架峪辣戒廊膛枝鲤Unit 5 New课件Unit 5 New课件;Atherosclerosis is a disease of the arteries in which fatty material and plaque are deposited in the wall of an artery, resulting in narrowing of the arterial lumen and eventual impairment of blood flow. ;屡叠浙塑苞姐鸵鸥谐牲垃钢附骇补干绸竹疯澎甥芒紫捏益慨淬美吨宪淋畦Unit 5 New课件Unit 5 New课件;王审凄拨绅剿纱漆吓缚咬侥拒粟昨劲裤哗榆疾世霉茎他专薛栏赞枪砒资叉Unit 5 New课件Unit 5 New课件;Atherosclerosis is a process by which fat and calcium build up in the inner lining of the arteries, forming a plaque.
