Arterial remodelling and eccentricity of plaque

Glagovian remodelling, plaque composition, and stenosis generation.

The role of microRNAs in arterial remodelling.

Adaptive alterations of the vessel wall architecture, called vascular remodelling, can be found in arterial hypertension, during the formation of aneurysms, in restenosis after vascular interventions, and in atherosclerosis. MicroRNAs (miR) critically affect the main cellular players in arterial remodelling and may either promote or inhibit the structural changes in the vessel wall. They regula...

Coronary artery remodelling is related to plaque composition.

OBJECTIVE To assess the potential relation between plaque composition and vascular remodelling by using spectral analysis of intravascular ultrasound (IVUS) radiofrequency data. METHODS AND RESULTS 41 coronary vessels with non-significant (< 50% diameter stenosis by angiography), < or = 20 mm, non-ostial lesions located in non-culprit vessels underwent IVUS interrogation. IVUS radiofrequency ...

Coronary artery disease: arterial remodelling and clinical presentation.

OBJECTIVE To investigate the hypothesis that in coronary artery disease large plaques in compensatorily enlarged segments are associated with acute coronary syndromes, whereas smaller plaques in shrunken segments are associated with stable angina pectoris. METHODS Patients selected for percutaneous transluminal coronary angioplasty (PTCA) were divided into two groups, one with stable angina p...

تاثیر استرس بر تغییرات شریانی (arterial remodelling) قلب در موش صحرائی نژاد ویستار

گزارشات نشان داده اند، برخی افراد که که به طور طولانی مدت زندگی پراسترس دارند، علیرغم دارا نبودن ریسک فاکتورهای بیماریهای قلبی عروقی، به بیماری های قلب و عروق و انسداد عروق مبتلا شده اند. بنابراین استرس، یکی از مهمترین عوامل موثر در بروز بیماری قلبی- عروقی محسوب می شود. در مطالعه حاضر،اثر احتمالی استرس مزمن شنای اجباری و استرس صدا در القای تغییرات بافتی عروق قلب با توجه به ساختار دیواره رگ ها و...
