چکیده
Correspondence to: Professor Thomas H Marwick, University of Queensland Department of Medicine, Princess Alexandra Hospital, Ipswich Road, Brisbane, Q4102, Australia; tmarwick@ soms.uq.edu.au _________________________ D iastolic dysfunction has a major impact on symptom status, functional capacity, medical treatment, and prognosis in both systolic and diastolic heart failure (HF), irrespective of the cause. w2 When systolic dysfunction is clearly present, the central clinical question concerns the presence or absence of elevated filling pressure; a restrictive filling pattern is highly specific for elevated pulmonary wedge pressure in this setting. w3 The transmitral flow pattern is also predictive of outcome; non-reversibility of restrictive filling with treatment portends a very poor prognosis. Thus, diastolic evaluation is an important component of the evaluation of the patient with systolic left ventricular (LV) impairment.

Prevalence of Heart Failure in the Cases of Beta-thalassemia Major; Two Years Follow-Up
Inroduction: Heart failure (HF) is an important cause of morbidity and mortality in the cases of Beta-thalassemia major. The purpose of this study was to estimate HF prevalence in these patients and to assess the survivability of those who were treated with intensive chelating therapy. Design and methods: This cross sectional study included 72 beta-thalassemia major cases, the mean age at t...
متن کاملAssessment of left ventricular diastolic function with cardiovascular MRI: what radiologists should know.
Diastolic dysfunction is a common entity and the predominant cause of heart failure in 40%-50% of patients. Diagnosis of diastolic dysfunction is clinically relevant and associated with a poor prognosis. The aim of this essay was to review the pathophysiology and different grades of diastolic dysfunction and to provide an overview on the role of cardiovascular magnetic resonance...

Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...
