Progression of Coronary Atherosclerosis
To determine whether calcium channel blockers influence the progression of coronary atherosclerosis, 383 patients age 65 years or less with 5-75% stenoses in at least four coronary artery segments were selected at random within 1 month of coronary arteriography to participate in double-blind therapy with a placebo or nicardipine 30 mg three times daily. Coronary events (5 deaths, 22 myocardial ...
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 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 کاملPrognostic significance of progression of coronary atherosclerosis.
BACKGROUND Angiographic progression of coronary atherosclerosis is frequently observed in clinical practice and is used as an end point in clinical trials; however, its prognostic significance is unclear. METHODS AND RESULTS Progression defined as an increase in diameter stenosis by > or = 15% of at least one coronary lesion was seen in 141 (42%) of 335 patients who underwent repeat coronary ...
متن کاملRapid Progression of Coronary Atherosclerosis: A Review
Atherosclerosis is chronic disease, the prevalence of which has increased steadily as the population ages. Vascular injury is believed to be critical initiating event in pathogenesis of spontaneous atherosclerosis. Syndrome of accelerated atherosclerosis has been classically described in patients undergoing heart transplantation, coronary artery bypass graft, and percutaneous transluminal coron...
