BACKGROUND: Any cardiac surgery under cardiopulmonary bypass (CPB) will induce ischemia-reperfusion injury and systematic inflammatory response, which may lead to exacerbation. Conventional therapy strategy is to use inotropes, diuretics and vasodilator drugs, yet, the therapeutic effects of which need to be improved. Recombinant human B-type natriuretic peptide (rhBNP) has been shown to be efficacious in the treatment of acute decompensated heart failure and acute myocardial infarction...

Telmisartan, a type of angiotensin II (Ang II) receptor inhibitor, is a common agent used to treat hypertension in the clinic. Hypertension increases cardiac afterload and promotes cardiac hypertrophy. However, the ventricular Ang II receptor may be activated in the absence of hypertension. Therefore, telmisartan may reduce cardiac hypertrophy by indirectly ameliorating hypertensive symptoms and directly inhibiting the cardiac Ang II receptor. Nuclear factor of activated T‑cells (NFAT) contributes to cardiac hypertrophy via nuclear translocation, which induces a cascade of atrial natriuretic peptide (ANP) and brain/B‑type natriuretic peptide (BNP) expression and cardiomyocyte apoptosis...

BACKGROUND: The N-terminal fragment of the prohormone brain-type natriuretic peptide (NT-proBNP) is a powerful predictor of adverse outcomes in patients with coronary artery disease (CAD). However, little is known regarding the prognostic significance of longitudinal changes in NT-proBNP levels. METHODS: We evaluated the ability of 5-year changes in NT-proBNP levels to predict subsequent heart failure (HF) hospitalization or cardiovascular (CV) death in 635 participants with stable CAD enrolled in the Heart and Soul Study...

Because hepatic dysfunction is common in patients with heart failure (HF), the Model for End-Stage Liver Disease (MELD) may be attractive for risk stratification. Although alternative scores such as the MELD-XI or MELD-Na may be more appropriate in HF populations, the short-term clinical implications of these in patients with acute heart failure (AHF) are unknown. The MELD-XI and MELD-Na were calculated at baseline in 453 patients with AHF in the DOSE-AHF and ROSE-AHF trials. The correlations and associations for each score with cardiorenal biomarkers, short-term end points at 72 hours including worsening renal function and clinical events to 60 days were determined...

BACKGROUND: Plasma B-type natriuretic peptide (BNP) concentration reflects cardiac dysfunction and assists in determining the diagnosis and prognosis of heart failure (HF). Current BNP assays overestimate circulating bioactive BNP1-32 concentrations as they also detect less active BNP metabolites and proBNP. A specific BNP1-32 assay with negligible cross-reactivity to proBNP and/or BNP metabolites may be advantageous. METHODS: We developed a Luminex-based specific BNP1-32 immunoassay and compared results obtained from 3 other BNP assays (a Luminex-based total-BNP assay, our BNP RIA, and the commercially available Abbott Architect BNP assay) in plasma from 42 patients with HF and 22 healthy controls...

PURPOSE OF REVIEW: Historically, pleural effusions have been attributed to a single cause. There is growing recognition that a substantial proportion of pleural effusions may have more than one underlying cause. The purpose of this review is to summarise recent findings regarding the diagnosis and treatment of effusions secondary to more than one aetiology. RECENT FINDINGS: A recent prospective study identified that 30% of pleural effusions had more than one underlying aetiology...

Polycystic kidney disease (PKD) involves progressive hepatorenal cyst expansion and fibrosis, frequently leading to end-stage renal disease. Increased vasopressin and cAMP signaling, dysregulated calcium homeostasis, and hypertension play major roles in PKD progression. The guanylyl cyclase A agonist, B-type natriuretic peptide (BNP), stimulates cGMP and shows anti-fibrotic, anti-hypertensive, and vasopressin-suppressive effects, potentially counteracting PKD pathogenesis. Here, we assessed the impacts of guanylyl cyclase A activation on PKD progression in a rat model of PKD...

BACKGROUND: Worsening renal function, indicated by increased serum creatinine (SCr), is a common complication of percutaneous coronary procedures. Risk factors for increased SCr overlap with coronary risk factors involved in endothelial dysfunction. We hypothesized that endothelial dysfunction, measured using the reactive hyperemia peripheral arterial tonometry index (RHI), can predict periprocedure-increased SCr. METHODS: RHI was assessed before elective coronary procedures in 316 consecutive stable patients with a preserved estimated glomerular filtration rate (eGFR, >60mL/min/1...
