Although the bipyridine agent amrinone is reported to have a positive inotropic effect on the left ventricle, the effect of this drug on right ventricular contractility in the clinical setting is unknown. We studied the effect of short-term intravenous administration of amrinone on right ventricular systolic function in nine patients with severe congestive heart failure and, using radionuclide ...

Abboud Department of Computer Science and Information Technology, University Putra Malaysia, 43400, Serdang, Malaysia Email: [email protected] Abstract: Accurate detection of the End-Diastolic (ED) and EndSystolic (ES) frames of a cardiac cycle are significant factors that may affect the accuracy of abnormality assessment of a ventricle. This process is a r...

BACKGROUND This study was to investigate the feasibility of real-time 3-dimensional echocardiography (RT3DE) for the analysis of biventricular ejection fractions and volume measurements in patients with cor pulmonale and the correlations of RT3DE results with 64-slice multi-detector cardiac computed tomography (64-MDCT) results. METHODS This study included a total of 22 patients (59.3 ± 16.6 ...

purpose: to compare ophthalmic artery velocity in eyes with nonarteritic anterior ischemic optic neuropathy (naion) with that of normal fellow eyes. methods: in this case-control study, 20 patients with unilateral naion and disease onset less than 8 weeks, were enrolled. using color doppler imaging, mean, maximum systolic and end diastolic ophthalmic artery velocities were evaluated. the result...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : supervised exercise-based cardiac rehabilitation programs (crp) have been suggested to all patients, especially after myocardial infarction. however, the effects of cardiac rehabilitation on systolic function are controversial. the aim of this study was to examine the effects of an 8-week cardiac rehabilitatio...

BACKGROUND We assessed changes in left ventricular (LV) volume and function and in regional myocardial wall stress in noninfarcted segments after restrictive mitral annuloplasty (RMA) with or without surgical ventricular restoration (SVR). METHODS AND RESULTS Thirty-nine patients with ischemic cardiomyopathy (ejection fraction ≤ 0.35) and severe mitral regurgitation (≥ 3) were studied before ...

We investigated the effect of pacing from the atrium and various ventricular sites on the left ventricular end-systolic pressure-volume relation following autonomic blockade in a total of 10 dogs chronically instrumented to measure left ventricular pressure and determine left ventricular volume from three ultrasonic endocardial dimensions. During ventricular pacing, left ventricular end-diastol...

a 40-year-old male patient with suicidal ingestion of one tablet of aluminium phosphide was referred to the department of toxicology emergency of baharloo hospital, tehran, iran. the garlic odor was smelled from the patient and abdominal pain and continuous vomiting as well as agitation and heartburn were the first signs and symptoms. systolic and diastolic blood pressures at the arrival time w...
