The efficacy of telenursing on caregiver burden among Iranian patients with heart failure: A randomized clinical trial.

Background: Heart failure is one of the most common syndromes in the world and Iran. Caring for heart failure patients can cause a burden on their caregivers. Traditional and modern treatment techniques are often used for patients with heart failure.

Myocardial iron load measured by cardiac magnetic resonance imaging to evaluate cardiac systolic function in thalassemia.

Background: The assessment of cardiac iron overload in thalassemia major has been considered as an important predictive factor of heart injury. The magnetic resonance imaging (MRI)-derived relaxation time parameter (T2*) varies inversely with iron level, and elevated myocardial iron levels by T2* are associated with depressed left ventricular (LV) ejection fraction (EF). We compared echocardiographic (ECHO) indices of systolic function to myocardial T2* in these patients.
