coronary artery bypasses grafting
this article describes coronary artery bypass grafting by avlliath jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. the aim of coronary artery bypass grafting is to release pain, prevention of myocardial inf...
متن کاملComputational study of the risk of restenosis in coronary bypasses.
Coronary artery disease, caused by the buildup of atherosclerotic plaques in the coronary vessel wall, is one of the leading causes of death in the world. For high-risk patients, coronary artery bypass graft is the preferred treatment. Despite overall excellent patency rates, bypasses may fail due to restenosis. In this context, the purpose of this work was to perform a parametric computational...
متن کاملPatients’ Cognitive Status and Its Related Factors Before Coronary Artery Bypasses Grafting
Introduction: Cognitive status of patients before Coronary Artery Bypass Grafting (CABG) affects their activities of daily living. Evaluation of cognition status and its related factors can help caregivers to plan suitable care programs. Objective: This study aimed to evaluate the patient’s cognition status and its related factors before CABG. Materials and Methods: This cross-sectional study...
متن کاملComparison of the Graft Angles Effects on the Temporal Wall Shear Stress Gradients in the Aorto-Coronary and Coronary-Coronary Bypasses
In this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal Wall Shear Stress (WSS) on the toe, heel and some locations on the bed of the Left Anterior Descending (LAD) artery at the anastomoses areas in the Aorto-Coronary (AC) and Coronary-Coronary (CC) bypasses. Flow fields in both bypasses with angles of...
متن کاملPinwheels and bypasses
We give a necessary and sufficient condition for the addition of a collection of disjoint bypasses to a convex surface to be universally tight – namely the nonexistence of a polygonal region which we call a virtual pinwheel.
