INTRODUCTION AND OBJECTIVE This study was designed to evaluate the reproducibility of ejection fraction (EF) and ventricular volume measurements obtained with single photon emission computed tomography (gated-SPECT), and to assess the correlation between EF values obtained with this method and blood pool planar radionuclide ventriculography. PATIENTS AND METHOD A total of 55 patients were inc...
We report on a 40 year old woman who presented with typical unstable angina pectoris associated with pulmonary oedema, due to poorly controlled hyperthyroidism. No cardiac abnormality was detected by echo-Doppler and nuclear ventriculography. Coronary angiography demonstrated normal coronary arteries. This case represents a new manifestation of the known association of cardiac ischaemia with hy...
Histopathologic-electrographic studies of ventriculography depicted nitroglycerin responsive and unresponsive asynergic areas were performed in 25 patients. Of 29 areas, 12 improved with nitroglycerin, showing < 10% muscle loss. Seventeen unimproved zones demonstrated significant fibrosis. Epicardial electrograms showed R waves in eight of nine improved zones. Of 11 unimproved zones, eight had ...
BACKGROUND Coenzyme Q10 is commonly used to treat congestive heart failure on the basis of data from several unblinded, subjective studies. Few randomized, blinded, controlled studies have evaluated objective measures of cardiac performance. OBJECTIVE To determine the effect of coenzyme Q10 on peak oxygen consumption, exercise duration, and ejection fraction. DESIGN Randomized, double-blind...
A patient with rheumatic mitral valve stenosis and regurgitation presented with shortness of breath and a "noise" in her chest. Cardiac auscultation revealed an intermittent late systolic "whoop." An increase in severity of mitral valve insufficiency during the periods of "whoop" was observed by pulsed Doppler, hemodynamic tracings and left ventriculography.
