Myocardial ischemia and viability
This paper addresses the question of whether and how MCG tests that assess ischemia or viability of the myocardium can add to the diagnostic information gained from standard procedures in asymptomatic and symptomatic patients. We review the diagnostic performance of the exercise electrocardiogram (ECG), the exercise and pharmacological (stress) echocardiogram, the exercise and pharmacological m...
متن کاملTime course of thallium-201 redistribution after transient myocardial ischemia.
The mechanism and time course of thallium-201 (201T1) redistribution after transient myocardial ischemia was investigated in 27 anesthetized dogs given 1.5 mCi of 201Tl intravenously 10 minutes after occlusion of the left anterior descending coronary artery. Coronary reperfusion (RP) was accomplished 10 minutes after 2`TI administration. Transmural myocardial biopsies were obtained in situ from...
متن کاملSerial diffusion tensor MRI after transient and permanent cerebral ischemia in nonhuman primates.
BACKGROUND AND PURPOSE We measured the temporal evolution of the T2 and diffusion tensor imaging parameters after transient and permanent cerebral middle cerebral artery occlusion (MCAo) in macaques, and compared it to standard histological analysis at the study end point. METHODS Stroke was created in adult male macaques by occluding a middle cerebral artery branch for 3 hours (transient MCA...
متن کاملHybrid Imaging in the Assessment of Myocardial Ischemia and Viability
Myocardial ischemia results from a reduction in blood flow as a consequence of a coronary stenosis, which produces ischemia in the myocardial territories irrigated by the stenotic artery. Myocardial viability is a concept that derived from several studies in which it was observed that, even if revascularization occurred, an irreversible left ventricular contractile dysfunction remained. The ter...
متن کاملThe bispecific SDF1-GPVI fusion protein preserves myocardial function after transient ischemia in mice.
BACKGROUND CXCR4-positive bone marrow cells (BMCs) are critically involved in cardiac repair mechanisms contributing to preserved cardiac function. Stromal cell-derived factor-1 (SDF-1) is the most prominent BMC homing factor known to augment BMC engraftment, which is a limiting step of stem cell-based therapy. After myocardial infarction, SDF-1 expression is rapidly upregulated and promotes my...
