introduction: we aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic heart failure (hf) patients. methods: this procedure was carried out during an interventional study conducted in the cardiology department from jan 2012 to apr 2013. the hf patie...
Although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. We report a case of Hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalize...
the incidence and prevalence of obesity are fast increasing worldwide. various indices have been used to measure and assess obesity. the body mass index (bmi) is the most common and practical of these indices. overweight and obesity exert considerable adverse effects on the cardiovascular system. these effects are mediated through various neurohormonal and cytokine pathways, most of which are i...
Background and Aim: Heart failure (H.F) is a burgeoning prevalent problem worldwide, which has involved over 20 million people. Echocardiography is the best standard process in diagnosing H.F. Thus, it is one of the first measures which should be taken for patients referring to the emergency ward. In the present study, the rate of chest X-ray diagnostic accuracy with respect to the occurrence o...
BACKGROUND Mitral valve (MV) enlargement is a compensatory mechanism capable of preventing functional mitral regurgitation (FMR) in dilated ventricles. Total leaflet area and its relation with closure area measured by 3-dimensional (3D) echocardiography have been related to FMR. Whether these parameters can be assessed with other imaging modalities is not known. Our objectives are to compare ca...
a total of 14 cases of infective endocarditis (ie) in children aged 6 months to 10 years were seen from december 1987 to december 1992 at the pediatric unit of ayatollah taleghani medical center. the majority of patients (12 of 14) were between 5 and 10 years of age. acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. organis...
Introduction & Objective: Heart failure that is a major health problem with increasing incidence with the aging of the population often occurs as a result of ischemia and coronary artery disease. Allopurinol can protect the ischemic heart muscle and improve the use of energy during myocardial ischemia. The aim of the present study was to evaluate the effects of allopurinol on the left ventric...
background heart failure is a major cause of death in thalassemia. the study aimed to determine the diagnostic value of n terminal pro b type natriuretic peptide (nt-pro bnp), to early diagnose the cardiac involvement in beta- thalassemia major patients. materials and methods 80 thalassemia patients aged 7 to 18 years old (patients group), and 80 healthy age and gender matched controls were en...
Elevated sympathetic tone and b-AR desensitization are characteristics associated with heart failure (HF) contributors to the initiation of arrhythmia. Studies have shown that altered responsiveness in HF leads compartmentalization imparied sub-cellular cAMP signaling. Yet, if signaling is heterogeneously remodeled throughout intact heart, how this may contribute arrhythmia unknown. To assess w...
