متن کاملThe effect of turbulence model on predicting the development and progression of coronary artery atherosclerosis
A severe case of stenosis in coronary arteries results in turbulence in the blood flow which may lead to the formation or progression of atherosclerosis. This study investigated the turbulent blood flow in a coronary artery with rigid walls, as well as 80% single and double stenoses on blood flow. A finite element-based software package, ADINA 8.8, was employed to model the blood flow. The hemo...

متن کاملProgression of coronary atherosclerosis.
Two hundred sixty-two patients with 50% or greater obstruction of at least one coronary artery on the initial study underwent recatheterization 2-182 months later and were evaluated for progressive arterial changes. Progression was considered present if (1) a change from less than total obstruction to total obstruction occurred in any vessel; (2) a change from 70% or less to 90% or more occurre...
متن کاملPrognostic significance of coronary arteriography.
An index of severity of coronary artery disease is described which takes into account the site, severicy and number of ali iesions in the coronary arreries. A percentage figure is computed with low percentages indicating severe disease. Ten year follow-ip for 1050 medi caliy treated patients are given. During che period of observation the overali mortaiity rate was 6.3%. 68% of deaths occurring...
