Viability, Remodeling, and CABG
F ollowing myocardial infarction, left ventricular (LV) remodeling is characterized by increased LV end-diastolic and end-systolic volumes (ESV) and decreased LV ejection fraction (EF) (1). This process is driven by elongation of infarcted zones and changes within the unaffected myocardium, including myocyte hypertrophy and interstitial collagen deposition. With medical therapy, revascularizati...
متن کاملAssessment of Myocardial Viability and Protection during Cabg
Dynamic imaging with stress echocardiography has been evaluated as a method to distinguish viable from nonviable myocardium. It is well recognized that regional left ventricular dysfunction is often reversible and exists in territories of viable myocardium. l-4 Indeed, it is widely recognized that reversible segmental wall-motion abnormalities caused by transient myocardial ischemia are the hal...
متن کامل[Assessment of myocardial viability in patients before revascularization].
Information on myocardial viability can be useful to decide when coronary artery revascularization is indicated for patients with acute myocardial infarction (AMI) and left regional or global ventricular dysfunction. Difficulties in assessing viability arise because the same part of the ventricular wall can have a mixture of necrotic tissue and viable myocardium. Diagnostic markers of myocardia...
متن کاملFactors influencing cord blood viability assessment before cryopreservation.
BACKGROUND Cord blood (CB) viability determines product quality and varies with time and temperature of exposure before cryopreservation. Global viability assessment may not reflect viability of white blood cell (WBC) subsets, CD34+ cell viability, or hematopoietic stem/progenitor cells function. STUDY DESIGN AND METHODS We compared trypan blue (TB) and acridine orange/propidium iodide (AO/PI...
متن کاملComparison of the myocardial perfusion and wall motion results by ECG-Gated 99mTc-MIBI SPECT, before and after CABG for evaluation of myocardial viability [Persian]
It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...
