BACKGROUND Individuals with hypertension and hyperuricemia have an increased risk of coronary artery disease and cerebral vascular disease as compared to patients with normal uric acid levels. Our aim is to determine the prevalence of hyperuricemia in hypertensive patients in Taiwan, and whether serum uric acid (SUA) is associated with changes in renal(More)
BACKGROUND The serum concentration of C-reactive protein (CRP) is mildly elevated in patients with chronic congestive heart failure (CHF), but this level falls well within the range found in healthy subjects. Standard clinical assays for CRP lack sensitivity within the low reference range and thus cannot be used effectively for routine clinical risk(More)
BACKGROUND Circulating soluble (s) cell adhesion molecules (CAMs) are elevated in patients with congestive heart failure (CHF) and may play an important role in the pathogenesis of CHF by mediating the cell-cell interactions of the immune response. However, clinical data about the prognostic value of sCAMs are sparse. The purpose of this study is to(More)
The slope of the preload recruitable stroke work relationship (M(w)) is a highly linear, load-insensitive contractile index. To investigate whether M(w) can be determined from a single steady-state beat, 45 patients were studied during cardiac catheterization. Single-beat M(w) (SBM(w)) was calculated directly from the baseline stroke work and baseline left(More)
The left ventricular (LV) end-systolic pressure-volume relation (ESPVR) is a load-insensitive method for evaluating LV contractility, which needs invasive measurement. Some noninvasive methods substitute peak aortic pressure (Ps) for end-systolic LV pressure by assuming there is no difference between these pressures. However, this assumption has not been(More)
BACKGROUND The aim of this study was to ascertain whether expressions of adipokines in the myocardium or their circulating levels can provide prognostic information concerning patients with chronic heart failure (HF). METHODS AND RESULTS Circulating levels of 3 adipokines (leptin, adiponectin, and resistin), N-terminal pro-B-type natriuretic peptide(More)
A total of 32 patients without regional wall motion abnormality of the left ventricle underwent sequential tissue Doppler echocardiography and cardiac catheterization. Peak velocities of systolic (Sa), early diastolic (Ea), and late diastolic (Aa) motion of the mitral annulus were measured. Normal references for Sa, Ea and Aa were obtained from 138(More)
Pulmonary vein Doppler spectrum is highly load-dependent and thus has been used to estimate left ventricular (LV) filling pressure. However, the impact of LV function on pulmonary vein Doppler spectrum remains obscure because only load-sensitive indices were studied previously. In the present study, measurements of the pulmonary vein Doppler spectrum were(More)
BACKGROUND Although radial access for drug-eluting stent (DES) combined with rotational atherectomy (RA) in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary(More)
