BACKGROUND: Regenerating islet-derived protein 3 beta (Reg3β) is a cardiomyocyte-derived chemokine for macrophages that is upregulated after myocardial infarction (MI) in mice. Here, we hypothesized that monitoring Reg3β expression might provide specific information on the degree of cardiac inflammation, which is a key determinant in disease progression and prognosis of patients with acute coronary syndrome (ACS). METHODS AND RESULTS: The expression of Reg3β and other inflammatory markers including C-reactive protein (CRP) and myeloperoxidase (MPO) was measured by immunoblotting at serial time points in the hearts and serum of mice with acute MI...

BACKGROUND: Preeclampsia (PE) is considered a specific vascular disease in which endothelial dysfunction may be the crucial factor of its pathogenesis. It has been suggested that strontium (Sr) may play a role in the pathophysiology of PE. Our group established in a previous study the serum levels of Sr in healthy pregnancies, and the main aim of the present study was to evaluate Sr concentrations and oxidative status in preeclamptic women. METHODS: The study population included women with early-onset PE (E-PE, n = 39), late-onset PE (L-PE, n = 67) and serial samples from a subset of preeclamptic women (PE-ss, n = 20)...

Renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system play crucial roles in heart failure with reduced ejection fraction (HFrEF). Clinical trials provide strong evidence of prognostic benefits for combination therapy with angiotensin-converting enzyme inhibitor (ACEI) and β-blocker in the treatment of HFrEF. Angiotensin receptor blocker (ARB) is not superior to ACEI in improving mortality and an alternative for patients who are intolerant to ACEI. Prognostic evidence for triple therapy which combined angiotensin receptor blocker (ARB) and ACEI in addition to β-blocker therapy, is still controversial in HFrEF...

BACKGROUND AND PURPOSE: Emerging evidence suggests that an underlying atrial cardiopathy may result in thromboembolism before atrial fibrillation (AF) develops. We examined the association between various markers of atrial cardiopathy and the risk of ischemic stroke. METHODS: The CHS (Cardiovascular Health Study) prospectively enrolled community-dwelling adults ≥65 years of age. For this study, we excluded participants diagnosed with stroke or AF before baseline...

BACKGROUND: Plasma concentrations of natriuretic peptides have been shown to predict prognosis in heart failure (HF) patients with left ventricle (LV) dysfunction. It is still unclear if measurements after cardiac surgery are associated with any effect on the outcome. We aimed to prospectively investigate the longitudinal profile of serial evaluations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in ischemic HF patients undergoing Surgical Ventricular Reconstruction (SVR) and how NT-proBNP levels at different time-points are associated with the outcome...

AIMS: Semaphorin 4D (Sema4D) is expressed on platelets and T-cells and known to be involved in inflammation. The aims of this study include comparing Sema4D and N terminal pro brain natriuretic peptide (NT-proBNP) serum levels in heart failure (HF) patients to a control group, evaluating the correlation between Sema4D and NT-proBNP levels, and assessing Sema4D serum levels in HF patients during acute exacerbation and remission. METHODS AND RESULTS: Forty-five patients diagnosed with HF (based on echocardiographic findings, positive NT-proBNP levels, and normal C-reactive protein) and 11 healthy controls (declaring no chronic diseases or medications) comprised the study population...

OBJECTIVE: Heart failure (HF) is a clinical syndrome resulting from structural or functional damages. Although clinical trials have shown that the plasma renin-angiotensin system (RAS) activation decreases HF functional status and increases hospitalization for HF patients, the effect of intrarenal RAS activity is still unknown. In this study, we investigated the relationship between the New York Heart Association (NYHA) class, duration, and number of hospitalizations in the previous year and urinary angiotensinogen (UAGT) in patients with HF with reduced ejection fraction (HFrEF)...

Background: Pulmonary vascular disease, especially pulmonary hypertension, is an important complication of COPD. Bronchiectasis is considered not only a comorbidity of COPD, but also a risk factor for vascular diseases. The main pulmonary artery to aorta diameter ratio (PA:A ratio) has been found to be a reliable indicator of pulmonary vascular disease. It is hypothesized that the co-existence of COPD and bronchiectasis may be associated with relative pulmonary artery enlargement (PA:A ratio >1)...

BACKGROUND: Measurement of N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) might be useful for monitoring of cardiovascular disease in the elderly. However, it is not clear whether changes in these biomarkers are associated with changes in the cardiovascular risk profile and if this pattern could be modified by changes in lifestyle habits or medications. METHODS: We measured levels of NT-proBNP and cTnI in community-dwelling subjects (PIVUS study) upon visits scheduled at age 70 (n=1007), 75 (n=825) and 80 (n=602)...

BACKGROUND: Patients with coronary artery disease (CAD) are often asymptomatic and their condition can go largely untreated, resulting in severe outcomes. Therefore, there is an urgent need for new biomarkers of CAD. METHODS: In this cross-sectional study, 540 patients were recruited. We performed a preliminary study, which included nine CAD-positive and nine CAD-negative patients, wherein the biomarker NCAM-1 was identified using label-free mass spectrometry. We then validated the efficacy of NCAM-1 in 429 CAD-positive and 93 CAD-negative patients...

AIMS: The 2014 National Institute of Clinical Excellence (NICE) guidelines on the management of acute heart failure recommended using a plasma NT-proBNP threshold of 300pg/ml to assist in ruling out the diagnosis of heart failure (HF), updating previous guidelines recommending using a threshold of 400pg/ml. NICE based their recommendations on 6 studies performed in other countries. This study sought to determine the diagnostic and economic implications of using these thresholds in a large unselected UK population...

BACKGROUND: The lack of reliable predictors of the efficacy of drugs and devices in heart failure (HF) has presented a major hurdle to the development and evaluation of novel therapies. OBJECTIVES: To determine whether treatment-related changes in natriuretic peptides (NP) predict longer-term therapeutic effects in clinical trials of HF. METHODS: We conducted a trial-level analysis of 16 phase-3 chronic HF trials completed between 1987 and 2013 studying 18 therapeutic comparisons in 48,844 patients...

OBJECTIVES: Short-term prediction of pre-eclampsia using the sFlt-1/PlGF ratio is characterized by frequent false positive results. As such, no treatment can be recommended to test positive patients. Multiple measurements are common in these patients. AIM: To evaluate the influence of NT-proBNP, uric acid and the sFlt-1/PlGF ratio in the prediction of delivery with pre-eclampsia within one week in singleton pregnancies from 24 weeks 0 days to 36 weeks 6 days of gestation, with signs and symptoms of pre-eclampsia and a sFlt-1/PlGF ratio above 38...

Natriuretic peptides are a group of hormones including atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), C type (CNP), urodilatin and guanilyn. ANP (half-life: 2-4 min), is secreted by the atrium, BNP (half-life: 20 min) by the ventricle, CNP by the vascular endothelium, urodilatin by the kidney and guanylin by the intestine. These natriuretic peptides prevent water and salt retention through renal action, vasodilatation and hormonal inhibition of aldosterone, vasopressin and cortisol. These peptides also have a recently demonstrated metabolic effect through an increase of lipolysis, thermogenesis, beta cell proliferation and muscular sensitivity to insulin...

Ultrasound lung comets (ULCs) are a nonionizing bedside approach to assess extravascular lung water. We evaluated a protocol for grading ULC score to estimate pulmonary congestion in heart failure patients and investigated clinical and echocardiographic correlates of the ULC score. Ninety-three patients with congestive heart failure, admitted to the emergency department, underwent pulmonary ultrasound and echocardiography. A ULC score was obtained by summing the ULC scores of 7 zones of anterolateral chest scans...

Out of 163 STEMI patients, 33 presented left ventricular remodeling (LVR) as assessed by multiple cardiac magnetic resonance (CMR) scans. LVR patients were identified as EarlyLVR (LVR occurring between baseline and 3 months) or LateLVR (LVR occurring between 3 months and one year), and matched to non-remodeler patients in term of age, gender, anterior infarction, baseline LV ejection fraction and infarct size. ST2 and NT-proBNP were measured at baseline and 3 months. Systolic wall stress (SWS) was calculated by CMR...

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia in the emergency department. The CHA2 DS2 -VASc score helps to predict thromboembolic risk; however, the rate of other adverse cardiac events is more difficult to predict. HYPOTHESIS: The biomarker N-terminal pro-brain natriuretic peptide (NT-proBNP) has prognostic value in patients presenting to the emergency department with AF. METHODS: During a 1.5-year period, a prospective study was performed in consecutive patients presenting to the emergency department with AF on the presenting electrocardiogram...
