[Myocardial viability in a single-vessel disease: the role of a dobutamine stress echocardiography].
OBJECTIVE To investigate a group of patients that have a significant lesion in a single-vessel and to demonstrate whether or not the sensitivity and specificity of a dobutamine stress echocardiography (DSE) was valuable in the evaluation of myocardial viability for these patients. METHODS Twenty patients who had undergone percutaneous transluminal coronary angioplasty (PTCA) were studied. Thi...
متن کاملPathophysiology 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 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 کاملPrognostic value of dobutamine stress myocardial contrast perfusion echocardiography.
BACKGROUND Myocardial perfusion (MP) imaging with real-time contrast echocardiography (RTCE) improves the sensitivity of dobutamine stress echocardiography for detecting coronary artery disease. Its prognostic value is unknown. We sought to determine the value of MP and wall motion (WM) analysis during dobutamine stress echocardiography in predicting the outcome of patients with known or suspec...
