A comparison of myocardial perfusion gated SPECT studies obtained at rest and after stress.
OBJECTIVE To perform a comparison between post-stress and rest gated single-photon emission computer tomography (SPECT) myocardial perfusion imaging (MPI) studies to assess post-stress stunning and the variables underlying this phenomenon. SUBJECTS AND METHODS This was a prospective study of 318 consecutive adult patients undergoing stress and rest gated SPECT using a 2-day (99m)Tc-tetrofosmi...
متن کاملBenefit of ECG-gated rest and stress N-13 cardiac PET imaging for quantification of LVEF in ischemic patients.
BACKGROUND ECG-gated rest-stress cardiac PET can lead to simultaneous quantification of both left ventricular ejection fraction and flow impairment. In this study, our aim was to assess the benefit of rest and stress PET ejection fraction (EF) (EFp) in relation to single-photon emission computed tomography (SPECT) EF (EFs) and echocardiography EF (EFe). To this effect, the EFp was compared with...
متن کاملGender-specific differences in myocardial deformation and aortic stiffness at rest and dobutamine stress.
Elderly women have increased aortic and ventricular stiffness but preserved global systolic function. Possible gender differences in ventricular deformation attributed to increased aortic stiffness at rest or with positive inotropic stress remain unknown. Eighty-four subjects (mean age: 63±8 years) were assessed for aortic stiffness by pulse wave velocity and ventricular deformation at rest and...
متن کاملInternal thoracic artery graft (ITAG): patency and functional status at rest and during dobutamine-stress echocardiography.
BACKGROUND The patent internal thoracic artery graft (ITAG) usually has a diastolic fraction (DF) > 50% of the flow. The functional assessment can be evaluated by the coronary reserve index (CRI). OBJECTIVE The objective was to evaluate the patency and functional status of the ITAG through echocardiography and Doppler. METHODS Data from sixty-six patients who underwent dobutamine-stress ech...
متن کاملDobutamine stress 99mTc-tetrofosmin quantitative gated SPECT predicts improvement of cardiac function after carvedilol treatment in patients with dilated cardiomyopathy.
UNLABELLED We evaluated whether dobutamine stress (99m)Tc-tetrofosmin quantitative gated SPECT (D-QGS) could predict improvement of cardiac function by carvedilol therapy in patients with dilated cardiomyopathy (DCM). METHODS The study included 30 patients with idiopathic DCM and a left ventricular ejection fraction (LVEF) of <45%. D-QGS was performed in all patients to measure LVEF at rest a...
