Little is known of the prominent role of collaterals in chronic total coronary occlusions. In chronic total occlusions, the collaterals are capable of complete preservation of myocardial function or of providing a minimum perfusion for hibernating myocardium. Both the extent of preserved regional function and the duration of the occlusion would ...
12 de ago. de 2022 · Collateral arteries may act as natural bypasses that reduce hypoperfusion after a coronary blockage. 3D imaging of neonatal and adult mouse hearts, plus human fetal and diseased adult hearts, is ...
9 de sept. de 2021 · These include decreased progression (or regression) of coronary plaques/lesions in CAD, recruitment of collaterals, enhanced blood rheological properties, and improvement of endothelial function and coronary blood flow, as well as enhancement of vascular smooth muscle cell function[22,23,91].
1 de jun. de 2021 · Introduction. Coronary collateral circulation (CCC) is a natural anastomosis develops as a consequence of severe stenosis or total coronary occlusion in normal coronary circulation [1-3].The presence of different degrees of collateral circulation in patients with similar levels of coronary artery disease suggests that this important phenomenon is developed by complex mechanisms [4, 5].
22 de ago. de 2022 · Diabetic dyslipidemia impairs coronary collateral formation: An update. Coronary collateralization is substantially impaired in patients with type 2 diabetes and occlusive coronary artery disease, which leads to aggravated myocardial ischemia and a more dismal prognosis. In a diabetic setting, altered serum lipid profiles and profound ...
28 de feb. de 2024 · Background: The prognostic value of coronary collateral circulation (CC) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is underdetermined. The purpose of the study was to assess the prognostic value of current two CC grading systems and their association with long-term outcomes in patients with CTO underwent PCI.
21 de sept. de 2010 · In patients with CAD, a well-developed coronary collateral circulation contributes to reduction of infarct size, 68 LV dysfunction, 68 and mortality. 11 Coronary collaterals are present in one fourth of patients with normal coronary arteries or nonobstructive CAD. 21 Therapeutic promotion of collateral function is not only feasible but also effective 12,13 and represents an important ...
