…heterogeneous area whose contents move under pressure; cellulitis instead gives a diffuse oedematous picture without a demarcated fluid collection. Ultrasound also shows the depth of…
…adjacent reference segment presumed to be relatively normal. This assumption may be incorrect when atherosclerosis is diffuse, leading to underestimation of the overall disease burden…
…multivessel coronary artery disease, and diffuse disease increase the likelihood of cardiovascular collapse when PCI fails or flow is severely compromised. Clinical Presentation No reflow…
…stenosis, multivessel coronary artery disease, or diffuse disease. No reflow represents impaired antegrade myocardial perfusion in the absence of a flow limiting epicardial stenosis. It…
…more patients survive with severe, diffuse CAD that is no longer amenable to additional mechanical revascularization. Despite treatment with antianginal drugs and PCI or CABG…
…symptoms (SAMS). These range from diffuse myalgia with a normal CK and no functional impairment to myositis with muscle inflammation and elevated CK. Rhabdomyolysis is…
…is a protein misfolding disorder characterized by the extracellular deposition of misfolded fibrillar proteins in the myocardium, leading to a diffuse infiltrative cardiomyopathy [8, 15]…
…diagnostic. The severity of pain also has limited discriminatory value. Features suggesting myocardial ischaemia Ischaemic discomfort commonly: Is substernal and diffuse. Is described as pressure…
…outer epicardial layers, producing ST elevations over the ischemic zone [15]. In the earliest stages of ischemia, this may manifest as tall, positive hyperacute T…
…In contrast, preserved FFR with reduced CFR may indicate coronary microvascular dysfunction or diffuse epicardial disease. Concordantly normal FFR and CFR are associated with an…
