endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome x (csx) and beta blockers are used for the treatment of this syndrome. thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in csx patients. the study included 25 csx patients (20 female/ 5 ma...

background: cardiac dysfunction due to chronic anemia and hemosiderosis are the major causes of death among patients with thalassemia intermedia. this study was performed to compare the cardiac function in thalassemia intermedia patients with normal subjects by means of echocardiography. materials and methods: this was a case-control study performed on 22 patients affected by thalassemia interm...

objective: we sought to determine the usefulness of the 99mtc-mibi (mibi) washout rate for the evaluation of steroid therapy in cardiac sarcoidosis (cs). methods: eleven cs patients underwent mibi myocardial spect both before and 6 months after initiating steroid therapy. the washout rate (wor) of mibi was calculated using early and delayed polar map images. the washout score (wos) of mibi was ...

introduction:  in patients who underwent surgery to repair tetralogy of fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. the aim of present study was to assess the effects of pulmonary valve replacement on rig...

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: patients with β-thalassemia major (tm) develop iron overload through increased iron absorption and transfusional therapy and it’s the most important complication of tm. thalassemia is common in coastal regions and lands with low altitudes. the aim of this study is to determine the effect of high and low altitude on serum ferritin and treatment requirement in two groups of β-thalasse...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...
