Dynamic123I-BMIPP single-photon emission computed tomography in patients with congestive heart failure: Effect of angiotensin ii type-1 receptor blockade

Angiotensin II type 1 receptor blockers and congestive heart failure.

Congestive Heart Failure To the Editor: We read with great interest the review on angiotensin II type 1 receptor blockers by Michel Burnier.1 He quotes previous investigations, including the results of the Losartan Heart Failure Survival Study (ELITE II)2 and states that “. . .losartan was not superior to captopril in reducing morbidity and mortality. . .,” and concludes that “. . .one should b...

Image Optimization in Single Photon Emission Computed Tomography by Hardware Modifications with Monte Carlo Simulation

Introduction: In Single Photon Emission Computed Tomography (SPECT), the projection data used for image reconstruction are distorted by several factors, including attenuation and scattering of gamma rays, collimator structure, data acquisition method, organ motion, and washout of radiopharmaceuticals. All these make reconstruction of a quantitative SPECT image very difficult. Simulation of a SP...

The effect of progressive aerobic continuous training on angiotensin-1, angiotensin-2 and angiotensin-converting enzyme type 2 in patients with heart failure

Background: Chronic hypertension causes structural and functional changes in the heart, ultimately leading to heart failure (HF), which further increases mortality and morbidit. HF is a complex clinical syndrome caused by various structural or functional abnormalities of the heart that impair the filling capacity of the ventricles. The findings of various trials have shown the association betwe...

Clinical value of iodine-123 beta-methyliodophenyl pentadecanoic acid (BMIPP) myocardial single photon emission computed tomography for predicting cardiac death among patients with chronic heart failure.

In the present study, the effectiveness of 123I-beta-methyliodophenyl pentadecanoic acid (BMIPP) single photon emission computed tomography (SPECT) for predicting cardiac death of patients with chronic heart failure was evaluated. Abnormalities of fatty acid metabolism are found in patients with chronic heart failure and BMIPP was developed as a tracer for scintigraphic assessment of myocardial...
