OBJECTIVES This study sought to evaluate the relationship between brain natriuretic peptide (BNP), renal function, and the severity of congestive heart failure (CHF). BACKGROUND Both BNP and renal function are prognostic predictors in CHF patients. METHODS We measured the plasma BNP level in the aortic root and coronary sinus in 366 consecutive patients(More)
BACKGROUND Cardiotrophin-1 (CT-1) is a member of the interleukin (IL-6) family of cytokines and is increased in patients with chronic heart failure (CHF). AIMS To evaluate the prognostic role of CT-1 in patients with CHF. METHODS AND RESULTS We measured the plasma levels of CT-1, brain natriuretic peptide (BNP), and IL-6 in 125 patients with CHF.(More)
BACKGROUND The adipocyte-specific cytokine adiponectin, has cardioprotective effects, correlates with endogenous cardiac natriuretic peptides and adipocyte has guanylyl cyclase-A receptors of natriuretic peptides. AIMS To evaluate the effect of carperitide (atrial natriuretic peptide; ANP) on plasma adiponectin in patients with heart failure. METHODS(More)
AIMS To evaluate whether plasma high molecular weight (HMW) adiponectin provides prognostic information in addition to that obtained from clinical, haemodynamic, and biochemical variables previously known to be associated with a high mortality in chronic heart failure (CHF) patients. METHODS AND RESULTS We measured the plasma levels of total and HMW(More)
To prevent cardiovascular disease, targeting aldosterone synthesis and release may be clinically important. Aldosterone production in the adrenal gland is mediated mainly by the T-type calcium channel in vitro. Efonidipine inhibits both L- and T-type Ca channels. To compare the effects of efonidipine on neurohumoral factors with those of amlodipine, an(More)
BACKGROUND A recent study suggested that xanthine oxidase is activated in congestive heart failure (CHF). However, whether uric acid (UA) is secreted from the failing heart remains unknown, so it is currently unclear whether serum UA can provide prognostic information independent of brain natriuretic peptide (BNP). METHODS AND RESULTS Serum UA was(More)
BACKGROUND Adiponectin, which is an adipocyte-specific cytokine that has a beneficial effect in cardiovascular disease, may be downregulated by oxidative stress in patients with chronic heart failure (CHF). Plasma levels of both adiponectin and biomarkers of oxidative stress are increased and have a prognostic impact on CHF patients. METHODS AND RESULTS(More)
BACKGROUND No previous study has compared the transcardiac gradient of cardiac natriuretic peptides and prognosis. METHODS AND RESULTS To compare the prognostic value of the transcardiac increase in brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) in patients with chronic heart failure (CHF), the hemodynamic parameters and plasma levels(More)
BACKGROUND The prognostic role of serum C-reactive protein (CRP) in chronic heart failure (CHF) patients, especially those with nonischemic dilated cardiomyopathy (DCM), remains unknown. In the present study, whether CRP provides prognostic information in DCM patients was evaluated. METHODS AND RESULTS Neurohumoral factors and hemodynamics in 84(More)
BACKGROUND Direct comparison of transcardiac increase in brain natriuretic peptide (BNP) and NT-pro-BNP has not been performed previously. AIMS To evaluate the relation between BNP and NT-pro-BNP secretion, plasma levels and renal function. METHODS We measured the plasma levels of BNP and NT-pro-BNP in the aortic root and coronary sinus in 326(More)
