Low-dose adenosine stress echocardiography: Detection of myocardial viability
OBJECTIVE The aim of this study was to evaluate the diagnostic potential of low-dose adenosine stress echocardiography in detection of myocardial viability. BACKGROUND Vasodilation through low dose dipyridamole infusion may recruit contractile reserve by increasing coronary flow or by increasing levels of endogenous adenosine. METHODS Forty-three patients with resting dyssynergy, due to pre...
متن کاملAutomated assessment of myocardial viability after acute myocardial infarction by global longitudinal peak strain on low-dose dobutamine stress echocardiography.
BACKGROUND Low-dose dobutamine stress echocardiography (DSE) assesses myocardial viability at the early stage of acute myocardial infarction (AMI), but its assessment is subjective and variable. Automated function image (AFI) determines global longitudinal peak strain (GLPS) based on tissue tracking technique. The ability of GLPS obtained by AFI during dobutamine stress to assess myocardial via...

متن کاملDetection of myocardial viability by dobutamine stress echocardiography: incremental value of diastolic wall thickness measurement.
OBJECTIVE To assess the diagnostic accuracy of baseline diastolic wall thickness (DWT) alone and as an adjunct to dobutamine stress echocardiography (DSE) for prediction of myocardial viability in patients with ischaemic left ventricular (LV) dysfunction, with the recovery of resting function after revascularisation as the yardstick. PATIENTS 24 patients with ischaemic LV dysfunction (ejectio...
متن کاملPre-ejection tissue-Doppler velocity changes during low dose dobutamine stress predict segmental myocardial viability.
INTRODUCTION We tested the hypothesis that low dose dobutamine stress echocardiography (LDDSE) combined with tissue Doppler imaging (TDI) can be used for the quantitative assessment of the content of viable myocardium. METHODS Forty-one patients with coronary artery disease and left ventricular dysfunction (ejection fraction < or =40%), already scheduled for revascularisation, underwent echoc...
