Myocardial Viability by DE-MRI and Low-dose Dobutamine CMR
Introduction Dysfunctional myocardium that remains viable has the potential for contractile recovery after reperfusion. Dysfunctional but viable myocardium has been broadly divided into two closely linked pathophysiological states, myocardial hibernation and stunning. Stunned myocardium is the result of an ischemic insult leading to contractile dysfunction despite adequate reperfusion. Hibernat...
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...
متن کاملHigh-Dose Dobutamine Stress Cardiac MR Imaging for Detection of Myocardial Ischemia
Stress induced impairment of regional left ventricular function is a reliable indicator of transient myocardial ischemia [1, 13]. Therefore, the analysis of wall motion abnormalities by echocardiography in conjunction with a variety of different stress modalities has grown to a clinically established non-invasive test for the assessment of myocardial ischemia [2]. However, optimal echocardiogra...
متن کاملLow-dose dobutamine echocardiography detects reversible dysfunction after thrombolytic therapy of acute myocardial infarction.
BACKGROUND Dysfunction after thrombolytic therapy of acute myocardial infarction (MI) may be reversible. Early after myocardial infarction, both reversible and irreversible injury may be manifested by regional wall motion abnormalities. Improved wall thickening during dobutamine infusion (dobutamine-responsive wall motion) may accurately identify reversibly injured segments. METHODS AND RESUL...
متن کاملPrognostic value of myocardial viability and ischemia detected by dobutamine stress echocardiography early after acute myocardial infarction treated with thrombolysis.
OBJECTIVES The aim of the study was to assess the prognostic value of myocardial viability and ischemia detected by dobutamine stress echocardiography (DSE) in patients with acute myocardial infarction (AMI) treated with thrombolysis. BACKGROUND DSE can detect myocardial viability and ischemia early after AMI, but the prognostic importance of viability and ischemia in these patients has yet t...
