Association between serum ferritin level and diastolic cardiac function in patients with major β-thalassemia
Abstract Background Prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. Our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. Materials and Methods Sixty-six patients with major thalassemia were studied in Amir Kabir hospital, Arak, Iran. Serum ferritin levels ...
متن کاملCardiac resynchronization therapy acutely improves diastolic function.
BACKGROUND Invasive studies have shown that cardiac resynchronization therapy (CRT) acutely improves left ventricular (LV) systolic performance and lowers filling pressures in a majority of patients with medically-refractory severe heart failure. Measurements included LV volume, ejection fraction, PWD early (E-wave) and atrial (A-wave) velocities, diastolic filling time (DFT), and DTI early dia...
متن کاملExercise cardiac MR assessment of diastolic function
Background Dyspnea with exertion is a common symptom in patients with left ventricular (LV) systolic and diastolic dysfunction. Assessing changes in systolic and diastolic hemodynamic parameters with exercise is necessary to thoroughly characterize these patients. Evaluation of changes in LV systolic function with exercise stress cardiac magnetic resonance (MR) has been demonstrated previously ...
متن کاملCardiac Imaging to Evaluate Left Ventricular Diastolic Function.
Left ventricular diastolic dysfunction in clinical practice is generally diagnosed by imaging. Recognition of heart failure with preserved ejection fraction has increased interest in the detection and evaluation of this condition and prompted an improved understanding of the strengths and weaknesses of different imaging modalities for evaluating diastolic dysfunction. This review briefly provid...
متن کاملDiastolic function after cardiac and heart-lung transplantation.
The mechanical efficiency of left ventricular contraction and relaxation, the asynchrony of the onset of left ventricular relaxation, the time constant of left ventricular isovolumic pressure decay, and left ventricular chamber and myocardial stiffness were analysed in 32 patients after cardiac (24) and heart-lung transplantation (8). After cardiac transplantation left ventricular myocardial st...
