Decreased cardiac parasympathetic activity in chronic heart failure and its relation to left ventricular function.

The Relation between Left Ventricular Function and Serum Ferritin in Major Β-Thalassemia

Abstract Objective Cardiac dysfunction is a major cause of death in patients with beta thalassemia. In these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. Left ventricular ejection fraction was measured in major beta thalassemia (β-Th) patients to detect the rela...

Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease

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...

بررسی فراوانی نشانگر CTnI و عوامل مرتبط با آن در بیماران با دیاستولیک دیس‌فانکشن AHF (PEF)

Abstract Background: Diastolic heart failure comprises 50 percent of cases of heart failure. The implications of increased levels of cardiac troponin I (CTnI) on congestive heart failure with preserved systolic function (AHF PEF) have been poorly evaluated. We hypothesized that its level might be elevated in AHF PEF so this evaluation was done in patients referred to Taleghani hospital with ...

Evaluation of Cardiac Mitochondrial Function by a Nuclear Imaging Technique using Technetium-99m-MIBI Uptake Kinetics

Mitochondria play an important role in energy production for the cell. The proper function of a myocardial cell largely depends on the functional capacity of the mitochondria.  Therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. Although originally designed for evaluating myocardial perfusion, 99mTc...

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...
