Although the pathogenesis of myocardial stunning has not been definitively established, the
two major hypotheses are that it is caused by the generation of oxygen-derived free radicals …

Stress echocardiography (SE) is a well established and valid technique, widely used for the
diagnostic evaluation of patients with ischemic and nonischemic cardiac diseases. This …

Background Although both 201Tl scintigraphy and low-dose dobutamine echocardiography
(LDDE) have been proposed as effective methods of assessing myocardial viability, their …

Objectives. This study sought to evaluate the time course of improvement of left ventricular
(LV) dysfunction in stable patients and its implications on the accuracy of dobutamine …

PURPOSE: To assess whether normal myocardium can be distinguished from infarction at
magnetic resonance (MR) imaging with low doses of manganese dipyridoxyl diphosphate …

OBJECTIVES The aim of this study was to evaluate low-level exercise echocardiography
(LLEE) in detecting contractile reserve and predicting functional improvement of akinetic …

Objective: To determine whether the early assessment of coronary flow velocity reserve
(CFVR) by transthoracic Doppler echocardiography (TTDE) can predict myocardial viability …

Many non-invasive methods, such as imaging tests, have been developed aiming to add a
contribution to existing studies in estimating patients' prognosis after myocardial injury. This …

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 …

Spontaneous improvement of contraction and perfusion occurs after acute myocardial
infarction. The relative merit of low-dose dobutamine stress echocardiography (LDDE) and …
