AIMS It remains to be proven whether left ventricular (LV) peak systolic velocity indices (peak systolic annulus tissue velocities, ejection velocity, and strain rate) are more closely related to contraction than LV end-systolic echocardiographic indices (ejection fraction, fractional shortening, systolic annulus displacement, global strain, and ejection velocity time integral). The study aimed...

OBJECTIVES To determine the frequency, associated clinical factors, and prognostic significance of left ventricular (LV) diastolic dysfunction in systemic sclerosis (SSc). METHODS We studied 153 consecutive patients with SSc and divided the study sample into those with and without LV diastolic dysfunction using established age-based normal cut-offs for lateral tissue Doppler early mitral annu...

BACKGROUND/AIMS There are few data on the effects of low hemoglobin levels on the left ventricle (LV) in patients without heart disease. The objective of this study was to document changes in the echocardiographic variables of LV structure and function after the correction of anemia without significant cardiovascular disease. METHODS In total, 34 iron-deficiency anemia patients (35 ± 11 years...

AIMS To examine relationships between cardiac troponin T (cTnT) and parameters of left ventricular (LV) structure and function in patients with acute destabilized heart failure (HF) with preserved LV ejection fraction. METHODS AND RESULTS In 44 patients with acute heart failure (HF) with preserved left ventricular (LV) ejection fraction, parameters of LV structure and function were assessed v...

BACKGROUND The prevalence of subclinical left ventricular (LV) systolic dysfunction in asymptomatic hypertensive patients was determined using tissue Doppler imaging (TDI). METHODS AND RESULTS TDI-derived mitral annular velocities were acquired in 35 control subjects, 92 asymptomatic hypertensive patients with no heart failure (HHD), and 15 patients with diastolic heart failure (DHF). No sign...

BACKGROUND Aortic stiffening contributes to the left ventricular (LV) afterload, hypertrophy, and substrate for diastolic dysfunction. It is also known that aortic elastic properties could be investigated with color tissue Doppler imaging (TDI) in aortic upper wall. The purpose of this study is to evaluate the relation of aortic upper wall TDI and aortic stiffness and other parameters of LV dia...

To assess left ventricular (LV) diastolic function in children with systemic hypertension, 11 patients with hypertension (mean blood pressure 99 mm Hg) and 7 normal patients (mean blood pressure 78 mm Hg) underwent M-mode echocardiography and pulsed Doppler examination of the LV inflow. From a digitized trace of the LV endocardium and a simultaneous phonocardiogram, echocardiographic diastolic ...

background : left ventricular (lv) dyssynchrony is a prevalent feature in heart failure (hf) patients. the current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in hf patients with regard to the qrs duration and etiology. methods: the available data on the tissue doppler imaging (tdi) of 230 patients with refractory hf were analyzed. the patients were divided...

background: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...

INTRODUCTION Gout is a common metabolic disorder characterized by hyperuricemia and chronic inflammation. Previous studies show that hyperuricemia accelerates the occurrence and worsening of cardiovascular disease due to LV remodeling. However, it is still unclear whether hyperuricemia is the sole contributor to organic heart remodeling in patients with gout. In addition, there is a paucity of ...
