Sensitive method of detecting myocardial ischemia during dobutamine stress echocardiography.
To test the hypothesis that dobutamine-induced myocardial ischemia causes early-systolic asynchrony predominantly in the regional left ventricular wall, color kinesis (CK) images during dobutamine stress echocardiography (DSE) were recorded in 13 patients with coronary artery disease and in 10 patients without, all of whom showed normal wall motion at rest. Based on the visual interpretation of...
متن کاملDobutamine stress myocardial perfusion imaging.
In patients with limited exercise capacity and (relative) contraindications to direct vasodilators such as dipyridamole or adenosine, dobutamine stress nuclear myocardial perfusion imaging (DSMPI) represents an alternative, exercise-independent stress modality for the detection of coronary artery disease (CAD). Nondiagnostic test results (absence of reversible perfusion defects with submaximal ...
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 کامل[Predictors of myocardial contractile reserve in patients with nonischemic dilated cardiomyopathy. An echo-stress dobutamine study].
INTRODUCTION AND OBJECTIVES Myocardial contractile reserve studies with low-dose dobutamine echocardiography have been shown to be useful to assess functional myocardial status. However, the variables associated with contractile reserve after inotropic stimulation are not well known. PATIENTS AND METHOD We studied 50 patients (35 men, mean age 56.4 +/- 9.5 years) with nonischemic dilated card...
متن کاملLiver Oxidative Stress after Renal Ischemia-Reperfusion Injury is Leukocyte Dependent in Inbred Mice
Objective(s) There are some reports in recent years indicating that renal ischemia - reperfusion (IR) induces deleterious changes in remote organs such as liver. The aim of this study was to investigate whether leukocytes have a role on the induction of oxidative stress in liver after renal IR. Materials and Methods Inbred mice in IR donor group were subjected to renal IR injury. In sham don...
