Pathophysiology of myocardial hibernation. Implications for the use of dobutamine echocardiography to identify myocardial viability.
Since the pioneering works of Tennant and Wiggers, it has been known that total ischaemia leads to a prompt cessation of contraction and eventually results in the appearance of cell damage and irreversible myocardial necrosis. Accordingly, in the minds of many cardiologists, the discovery of an abnormal regional contraction in a patient with coronary artery disease had long been equated with th...

متن کاملUsefulness of myocardial parametric imaging to evaluate myocardial viability in experimental and in clinical studies.
OBJECTIVE To evaluate whether myocardial parametric imaging (MPI) is superior to visual assessment for the evaluation of myocardial viability. METHODS AND RESULTS Myocardial contrast echocardiography (MCE) was assessed in 11 pigs before, during, and after left anterior descending coronary artery occlusion and in 32 patients with ischaemic heart disease by using intravenous SonoVue administrat...
متن کاملPhantom studies for estimation of defect size on cardiac (18)F SPECT and PET: implications for myocardial viability assessment.
UNLABELLED SPECT with (18)F-FDG has emerged as an alternative to dedicated PET for the assessment of myocardial viability. However, whether FDG SPECT can reliably quantify the extent of viable and scarred myocardium is uncertain. The aim of this study was to investigate whether SPECT with an (18)F-labeled agent would provide information on defect size similar to that provided by dedicated PET. ...
متن کاملMyocardial 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...
