Heart failure (HF) is a primary cause of morbidity and mortality worldwide. As the most widely studied and commonly applied natriuretic peptide (NP), B-type natriuretic peptide (BNP) has the effects of diuresis, natriuresis, vasodilation, anti-hypertrophy, and anti-fibrosis and it inhibits the renin-angiotensin-aldosterone and sympathetic nervous systems to maintain cardiorenal homeostasis and counteract the effects of HF. Both BNP and N-terminal pro B-type natriuretic peptide (NT-proBNP) are applied as diagnostic, managing, and prognostic tools for HF...

AIMS: Wild-type transthyretin (ATTRwt) cardiac amyloidosis has emerged as an important cause of heart failure in the elderly. Atrial fibrillation (AF) commonly affects older adults with heart failure and is associated with reduced survival, but its role in ATTRwt is unclear. We sought to explore the clinical impact of AF in ATTRwt. METHODS AND RESULTS: Patients with biopsy-proven ATTRwt cardiac amyloidosis (n = 146) were retrospectively identified, and clinical, echocardiographic, and biochemical data were collected...

Depression and anxiety are prevalent in patients with heart failure (HF). Reduced ejection fraction (EF) and increased N-terminal-prohormone B-type natriuretic peptide (NT-proBNP) have been shown to be independently associated with depressive symptoms and may therefore increase HF disease progression and mortality. This study evaluated whether NT-proBNP mediated the impact of reduced EF on depressive and anxiety symptoms in patients with HF. Participants (n = 124) were patients with a diagnosis of chronic HF enrolled in the Heart Failure Disease Management Program at Health Sciences North...

INTRODUCTION: The determination of natriuretic peptide levels in patients hospitalized for suspected acute heart failure is important for the confirmation of the diagnosis and for the prognosis. Changes in natriuretic peptide levels in response to therapy have a strong prognostic value. AIM: To decide whether repeated natriuretic peptide measurements for acute heart failure show changes that could influence the diagnosis and/or the prognosis. METHOD: Prospective data collection was carried out of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels on admission and within 12 hours in patients hospitalized for acute heart failure...

Exercise intolerance is the first symptom of heart disease. Yet an objective and standardised method in canine cardiology to assess exercise capacity in a clinical setting is lacking. In contrast, exercise testing is a powerful diagnostic tool in humans, providing valuable information on prognosis and impact of therapeutic intervention. To investigate whether an exercise test reveals differences between dogs with early stage mitral regurgitation (MR) and dogs without cardiac disease, 12 healthy beagles (healthy group, HG) and 12 dogs with presymptomatic MR (CHIEF B1 / B2, patient group, PG) underwent a six-stage submaximal exercise test (ET) on a motorised treadmill...

Although high-risk human papillomavirus (HR‑HPV) infection has a prominent role in the aetiology of cervical cancer (CC), sex steroid hormones may also be involved in this process; however, the cooperation between oestrogen and HR‑HPV in the early stages of cervical carcinogenesis is poorly understood. Since 17β-oestradiol (E2) and the HPV type 16‑E7 oncoprotein induce CC in transgenic mice, a microarray analysis was performed in the present study to generate global gene expression profiles from 2‑month‑old FVB (non‑transgenic) and K14E7 (transgenic) mice who were left untreated or were treated for 1 month with E2...

BACKGROUND: B-type natriuretic peptide (BNP) is known to be a risk marker following acute myocardial infarction (MI). More recently, truncated molecular forms of the BNP molecule have been identified, with the association of these forms and outcome in acute MI not known. The present study investigated their use as risk stratifying biomarkers of this condition. METHODS: BNP molecular forms (BNP 5-32, BNP 4-32 and BNP 3-32) were measured in plasma from 1078 acute MI patients using immunocapture followed by MALDI-ToF-mass spectrometry...

Activation of the renin-angiotensin system (RAS) is associated with hypertension and heart disease. However, how RAS activation causes cardiac lesions remains elusive. Here we report the involvement of Wnt/β-catenin signaling in this process. In rats with chronic infusion of angiotensin II (Ang II), eight Wnt ligands were induced and β-catenin activated in both cardiomyocytes and cardiac fibroblasts. Blockade of Wnt/β-catenin signaling by small molecule inhibitor ICG-001 restrained Ang II-induced cardiac hypertrophy by normalizing heart size and inhibiting hypertrophic marker genes...

BACKGROUND: Left ventricular remodeling (LVR) after myocardial infarction is associated with an increased risk of heart failure and death. In spite of a modern therapeutic approach, LVR remains relatively frequent and difficult to predict in clinical practice. Our aim was to identify new biomarkers of LVR and understand their involvement in its development. METHODS AND RESULTS: Proteomic analysis of plasma from the REVE-2 study (Remodelage Ventriculaire)-a study dedicated to the analysis of LVR which included 246 patients after a first anterior myocardial infarction-identified increased plasma levels of CLU (clusterin) in patients with high LVR...

BACKGROUND: Pegylated interferon (pegIFN) in combination with ribavirin (RBV) has successfully improved the rate of sustained virological response (SVR) in chronic hepatitis C virus (HCV) infected individuals, which reduces the progression of the chronic liver disease. However, the influence of combination therapy (pegIFN/RBV) on cardiac function has yielded ambiguous results. The present study aimed to evaluate the effects of combination therapy with pegIFN/RBV on cardiac function of HCV-infected individuals with SVR...

BACKGROUND: N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) levels correlate with higher peri-procedural mortality after transcatheter aortic valve replacement (TAVR). The long-term prognostic value of NT-proBNP within the first days after TAVR, however, remains unclear. This study examined early changes in NT-proBNP prior to and within 6 days after TAVR, the diagnostic value of this biomarker regarding aortic regurgitation (AR), and its prognostic value regarding one-year mortality...

Ranolazine is generally used to treat anginal symptoms for patients with symptomatic chronic stable angina pectoris. By improving ischemia-reperfusion, ranolazine is also observed to have protective effects on myocardial ischemic injury in animal models. It is noteworthy to find interventions that can decrease adverse effects of this drug and thereby increase its clinical application. Thus, in this report we used a rat model of chronic ischemic heart failure (CHF) to examine if vagal stimulation can strengthen the effects of ranolazine on worsened cardiac function in CHF...

BACKGROUND: B-type natriuretic peptides (BNPs) have shown promise in detecting cardioembolic stroke. However, there has been little investigation comparing the diagnostic efficacy of BNP and its cleavage by-product N-terminal peptide (NT-proBNP) in cardioembolic stroke patients. Therefore, the aim of this meta-analysis will be to comparatively assess the diagnostic efficacy of BNP versus NT-proBNP in distinguishing cardioembolic stroke from non-cardioembolic stroke in adult ischemic stroke patients...
