Comparative ability of dobutamine and exercise stress in inducing myocardial ischaemia in active patients.
OBJECTIVE To compare the ability of dobutamine and exercise stress to induce myocardial ischaemia and perfusion heterogeneity under routine clinical circumstances. DESIGN 86 active patients without previous myocardial infarction were studied by dobutamine and exercise stress protocols and coronary angiography. During both tests patients underwent electrocardiography, digitised echocardiograph...
متن کاملCardiac outcomes with submaximal normal stress echocardiography: a meta-analysis.
OBJECTIVES The aim of the study was to evaluate the risk of cardiac events in patients with normal stress echocardiography (SE) who attained maximal age-predicted heart rate (APHR) compared with those who did not in the setting of both normal and abnormal SE. BACKGROUND SE is an important tool in the risk stratification and prognosis of patients with known or suspected coronary artery disease...
متن کاملComparative accuracy of real-time myocardial contrast perfusion imaging and wall motion analysis during dobutamine stress echocardiography for the diagnosis of coronary artery disease.
OBJECTIVE This study sought to compare the accuracy of myocardial contrast echocardiography (MCE) and wall motion analysis (WMA) during submaximal and peak dobutamine stress echocardiography (DSE) for the diagnosis of coronary artery disease (CAD). BACKGROUND The relative merits of MCE and WMA for the detection of CAD during DSE have not been studied in a large number of patients. METHODS W...
متن کاملMethodology, feasibility, safety and diagnostic accuracy of dobutamine stress echocardiography.
Large numbers of patients referred for evaluation of chest pain are unable to perform adequate, diagnostic exercise testing. In these patients, dobutamine stress echocardiography (DSE) represents an alternative, exercise-independent stress modality. Apart from the approximately 5% of patients with an inadequate acoustic window, 10% of patients referred for this test have nondiagnostic (submaxim...
متن کاملBenefits of combined pharmacologic and submaximal exercise stress on Sub-diaphragmatic activity in myocardial perfusion scintigraphy
Introduction: Myocardial perfusion imaging (MPI) is an important imaging modality in managing patients with cardiovascular disease. MPI has a significant role in diagnosis and management of cardiovascular disease; however it is subjected to different artifacts. Combining pharmacologic stress with submaximal exercise reduces side effects, improves image quality, and enhances the...
