BACKGROUND Vascular endothelial growth factor (VEGF) plays a pivotal role in angiogenesis. This study tested the association between functional VEGF +405 C>G (rs2010963), -2578C>A (rs699947) polymorphisms, and coronary collaterals in patients with coronary artery disease (CAD). METHOD The collateral scoring system developed by Rentrop was used to classify(More)
Previous studies which included patients with preserved left ventricular (LV) systolic function demonstrated that arterial stiffness progressively increased as LV diastolic function decreased. However, it was unknown whether this correlation was still present in a heterogeneous study population involving patients with a wide range of LV systolic function.(More)
BACKGROUND AND OBJECTIVES Increased arterial stiffness was reported to be associated with decreased estimated GFR (eGFR). Previous studies suggested that arterial stiffness might play a role in renal function progression in patients with chronic kidney disease (CKD). The aim of this study was to investigate whether there was an independent association(More)
Heart failure and increased arterial stiffness are associated with declining renal function. This longitudinal study was designed to assess whether the combination of brachial-ankle pulse wave velocity (baPWV) and the ratio of brachial pre-ejection period (bPEP) to brachial ejection time (bET) was independently associated with renal outcomes in patients(More)
OBJECTIVES Increased arterial stiffness is associated with left ventricular diastolic dysfunction (LVDD), but this association may be influenced by left ventricular (LV) performance. Left ventricular hypertrophy (LVH) is not only a significant determinant of LV performance, but is also correlated with LVDD. This study is designed to compare LV diastolic(More)
OBJECTIVES To test the association between fasting glucose level and left ventricular mass (LVM) and left ventricular hypertrophy (LVH) in people aged 60 and older. DESIGN Population-based prospective study with 4-year follow-up. SETTING Department of Internal Medicine and Family Medicine, Kaohsiung Medical University (KMU), Chung-Ho Memorial Hospital,(More)
BACKGROUND Using tissue Doppler echocardiography, we can measure preejection period (PEPa), defined as the interval measured from the onset of QRS to the onset of the systolic mitral annular velocity pattern, isovolumic relaxation time (IVRTa), defined as the interval measured from the end of systolic mitral annular velocity pattern to the onset of(More)
BACKGROUND The aim of this study is to correlate Tei index obtained from tissue Doppler echocardiography (TDE-Tei index) defined as the ratio of the sum of isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) over the ejection time (ET) with invasive measurements of left ventricular (LV) performance. METHODS Thirty-four patients(More)
BACKGROUND AND OBJECTIVES Cardiac abnormalities were frequently noted in patients with chronic kidney disease (CKD). This study is designed to assess whether echocardiographic parameters are associated with rate of renal function decline and progression to dialysis in CKD stage 3 to 5 patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This(More)
OBJECTIVE The aim of this study is to evaluate and compare the impact of preload alterations by haemodialysis (HD) on the Tei index obtained by pulsed Doppler echocardiography (PDE-Tei index) and tissue Doppler echocardiography (TDE-Tei index). METHODS AND RESULTS Thirty-eight uraemic patients underwent echocardiography 1 hour before and 1 hour after HD(More)
