Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

RATIONALE AND OBJECTIVES The aim of this study was to apply a decision analytic model for the evaluation of coronary artery disease (CAD) to define the optimal utilization of coronary computed tomographic angiography (cCTA) and stress testing. MATERIALS AND METHODS The model tested in this study assumes that CAD is evaluated with a stress test and/or cCTA and that a patient with positive eval...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...

INTRODUCTION AND OBJECTIVES The ability of stress echocardiography to provide prognostic information that supplements that obtainable from clinical data and exercise electrocardiography is still controversial. Our aim was to determine whether dobutamine stress echocardiography provides additional information on long-term prognosis after conventional exercise testing has indicated that a patient...
