Background
The aim of this prospective study was to assess the usefulness of global longitudinal strain (GLS), regional diastolic and systolic strain, strain rate (SR) parameters at rest and during dobutamine stress echocardiography for detecting significant coronary artery stenosis in patients with a moderate or high probability of coronary artery disease (CAD).
Methods
Dobutamine stress echocardiography...
Myocardial deformation indices are considered as sensitive markers of ischemia and may be useful in the quantification of hemodynamic significance of coronary artery disease (CAD). We sought to determine the diagnostic value of speckle-tracking echocardiography derived myocardial deformation parameters at rest and during stress to determine hemodynamically significance coronary artery stenosis in...
Low-T3 syndrome is common in patients with acute myocardial infarction (AMI). Recent experimental and clinical data have suggested a potential negative impact of low-T3 syndrome on myocardial function in patients with AMI. The aim of this study was to assess left ventricular (LV) myocardial function in patients with low-T3 syndrome and to investigate the association between hormonal profile and the...
The aim of the study was to investigate the relation between health-related quality of life (HRQoL) and left ventricular systolic and diastolic function parameters in stable coronary artery disease (CAD) patients with mild and moderate heart failure.This study included 758 CAD patients. Left ventricular ejection fraction (LVEF) and ratio of peak velocities of early (E) and late (A) diastolic mitral...
Background Recent clinical studies have found that cardiovascular incidents are sufficient triggers to affect HPA hypothalamic-pituitarythyroid axis and cause a decrease in the serum levels of triiodothyronine (T3). This phenomenon is so called ‘Low — triiodothyronine (T3) syndrome’ and is related to changes in heart remodeling. However, the pathophysiology of Low—T3 syndrome remains unclear. The...
