چکیده

Background Epicardial adipose tissue, aortic stiffness and myocardial fibrosis have been linked to cardiovascular risk and disease; however, often different modalities are used for their measurement. Cardiac magnetic resonance (CMR) may be used to determine these parameters in a single examination by the measurement of epicardial fat volumes (EFV), aortic pulse wave velocity (PWV) as a parameter of aortic stiffness, and T1-relaxation time (T1) as a marker for myocardial fibrosis. This quantitative CMR-study was performed to identify relationships between these parameters in healthy individuals and to correlate them with age, body mass index (BMI) and gender.

Epicardial adipose tissue volume by cardiac magnetic resonance imaging predicts abnormal myocardial relaxation in patients with atrial fibrillation

Background Inflammation may be a key trigger in the accumulation of extracellular matrix that leads to fibrosis, abnormal myocardial relaxation, diastolic dysfunction and eventual heart failure with a preserved ejection fraction (HFpEF). Epicardial adipose tissue (EAT) is a metabolically active organ releasing various adipokines and inflammatory mediators which may promote fibrosis in adjacent ...

Effect of high- intensity interval training on tissue changes of collagen type 1 and fibrosis percent in male rats with myocardial infarction

Introduction: Myocardial infarction (MI) is defined pathologically as cardiac muscle cell death due to abnormal blood flow, prolonged coronary artery ischemia, and replacement of cardiac tissue necrosis as a dense fibrotic lesion. Expression of collagen-1 protein levels and fibrosis increase after myocardial infarction in cardiac tissue. The aim of present study was to investigate the effect of...

Evaluation of tissue doppler echocardiography and T2* magnetic resonance imaging in iron load of patients with thalassemia major

Background: Iron-mediated cardiomyopathy is the main complication of thalassemia major (TM) patients. Therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. The aim of this study was to evaluate the efficacy of tissue doppler imaging (TDI) to study cardiac iron overload in patients with TM using T2* magnetic resonance (MR) as the gold-standard...

Relationships between epicardial adipose tissue thickness and adipo-fibrokine indicator profiles post-myocardial infarction

BACKGROUND Determination of the impact of visceral obesity and epicardial adipose tissue thickness on stimulating growth factor levels during hospitalization for myocardial infarction is of potential importance for predicting outcomes and assessing the development of cardiofibrotic changes associated with maladaptive myocardial remodeling. In this study, we aimed to investigate the relationship...
