OBJECTIVE: To investigate how many patients with acute heart failure (AHF) hypersecrete relaxin-2 concentrations similar to those of pregnant women and determine their long-term outcome. METHODS: In consecutive AHF patients relaxin-2 was quantified by ELISA sandwich method. Patients were divided into pregnancy-like group (PLG, relaxin-2 ≥ 500 pg/mL) and control group (CG, relaxin-2 < 500 pg/mL). The primary outcome was all-cause death during follow-up...

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)...

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...

CONTEXT: Circulating B-type natriuretic peptide, as measured by the N-terminal fragment of its prohormone (NT-proBNP), is inversely associated with incident type 2 diabetes (T2DM) but positively related to future cardiovascular disease (CVD). Recognizing that gestational diabetes (GDM) identifies women at future risk for both T2DM and CVD, we sought to determine whether gestational glucose tolerance relates to NT-proBNP in the years after delivery. DESIGN/PATIENTS/MEASUREMENTS: Three hundred and forty women underwent a glucose challenge test (GCT) and an oral glucose tolerance test (OGTT) in pregnancy, yielding 4 gestational glucose tolerance groups: GDM (n = 105); gestational impaired glucose tolerance (n = 59); abnormal GCT with a normal OGTT (n = 98); and normal GCT with normal OGTT (n = 75)...

Angiogenic and antiangiogenic factors have proven to be an accurate predictive means of preeclampsia. Echocardiographic studies have shown that women with preeclampsia exhibit significant cardiovascular strain, especially early-onset preeclampsia. The aim of this study is to determine preeclampsia risk with soluble fms-like tyrosin kinase 1/placental growth factor ratio, serum NT-proBNP (N-terminal pro B-type natriuretic peptide), and biophysical markers of cardiovascular function in a prospective case-control study...

BACKGROUND: Women with hypertensive disorders in pregnancy, in particular early-onset preeclampsia, are at increased risk of developing cardiovascular disease later in life. These women have a more than 2-fold increased risk of dying from cardiovascular diseases. Most studies have focused on identification of risk factors shortly after pregnancy. Less is known on the prevalence of risk factors or actual signs of cardiovascular disease 5-20 years later. The presence of hypertension or metabolic syndrome can be seen as an opportunity for preventive interventions to reduce the development of severe cardiovascular diseases like myocardial infarction and stroke...

OBJECTIVE: To evaluate B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac structure and function in normal women through pregnancy and the postpartum. METHODS: In this prospective observational study, we obtained serial transthoracic echocardiograms, BNP, and NT-proBNP at seven intervals from 6 weeks' gestation through 12 months postpartum. Women with hypertension or cardiac disease were excluded. Using 6-12 months postpartum as reference for non-pregnant levels, echocardiogram measurements and BNP/NT-proBNP were compared over time using linear mixed models with Tukey-Kramer adjustment for multiple comparisons...

OBJECTIVE: A proper maternal cardiovascular adaptation to the pregnancy plays a key role for promoting an adequate uteroplacental perfusion, for ensuring normal fetal development and for preventing gestational hypertensive complications such as preeclampsia. This study aims to evaluate hemodynamic measurements obtained by noninvasive methods among preclamptic women with and without fetal growth restriction (FGR) and the relationship with plasma levels of natriuretic peptides. STUDY DESIGN: The study compared 98 pregnant women (n=48 with preeclampsia; n=50 normotensive pregnant women) and 50 nonpregnant normotensive control subjects undergoing anultrasonic cardiac output monitor (USCOM) and plasma assessment of atrial N-terminal pro B-type natriuretic peptide (NT-proBNP)...

Common complications of pregnancy include preeclampsia (PE), gestational hypertension (GH) and gestational diabetes mellitus (GDM). Hypertensive disorders (PE/GH) and GDM may result in greater maternal, fetal and neonatal morbidity and mortality. Women with PE/GH, one of the most common causes of heart burden in an obstetrical setting, present with elevated serum levels of BNP and NT-proBNP. The aim of this study was to shed more light on the role of NT-proBNP in pathophysiology of PE, GH and GDM. The study included 156 pregnant women with singleton pregnancies...

Plasma levels of NT-proBNP are elevated in women with preeclampsia at the time of diagnosis. The objective of this case-control study was to evaluate N-terminal proBNP (NT-proBNP) in maternal plasma as an early second-trimester biomarker for prediction of early-onset preeclampsia. In early second-trimester samples, women who later developed preeclampsia at gestational age 34 wk + 0 or earlier (n = 16) had similar plasma levels of NT-proBNP (median 51.8, range 26.1-131.9 pg/ml) as women with uncomplicated pregnancy outcomes (n = 43) (53...

INTRODUCTION: Brain natriuretic peptide (BNP) is synthesized by human fetal membranes, both the amnion and chorion. This locally produced BNP inhibits the contraction of the human myometrium, contributing to the maintenance of myometrial quiescence during pregnancy. Reference values for NT-proBNP concentrations in amniotic fluid at different gestational ages have not been completely defined. We aimed to investigate the range of fetal NT-proBNP values in amniotic fluid in normal pregnancy between 17 and 41weeks of gestation...

BACKGROUND: Rheumatic heart disease (RHD) is a global cause of early heart failure. Early RHD is characterized by valvar regurgitation, leading to ventricular distention and possible elaboration of amino-terminal pro-brain natriuretic peptide (NT-proBNP). We investigated the ability of NT-proBNP to distinguish cases of latent RHD detected by echocardiographic screening from the controls. MATERIALS AND METHODS: Ugandan children (N = 44, 36% males, mean age: 12 ± 2 years) with latent RHD (cases) and siblings (controls) by echocardiography were enrolled...

BACKGROUND: Several biomarkers have individually been shown to be useful for risk stratification in patients with acute myocardial infarction (MI). The optimal multimarker strategy remains undefined. METHODS AND RESULTS: Biomarkers representing different pathobiological axes were studied, including myocardial stress/structural changes (NT-pro B-type natriuretic peptide [NT-proBNP], midregional proatrial natriuretic peptide [MR-proANP], suppression of tumorigenicity 2 [ST2], galectin-3, midregional proadrenomedullin [MR-proADM], and copeptin), myonecrosis (troponin T), and inflammation (myeloperoxidase [MPO], high sensitivity C-reactive protein [hsCRP], pregnancy-associated plasma protein A [PAPP-A], and growth-differentiation factor-15 [GDF-15]), in up to 1258 patients from Clopidogrel as Adjunctive Reperfusion Therapy-Thrombolysis in Myocardial Infarction 28 (CLARITY-TIMI 28), a randomized trial of clopidogrel in ST-elevation MI (STEMI)...

Purpose The amniotic fluid volume (AFV) is known as a predictor for the wellness of a fetus. We aimed to investigate whether N-terminal pro-brain natriuretic peptide (NTproBNP) levels reflect AFV abnormalities in otherwise normal fetuses. Methods We recruited 24 women with isolated oligohydramnios, 23 women with isolated polyhydramnios, and 36 women with normal AFV at a tertiary referral center. NT-proBNP levels in umbilical venous samples and the individual characteristics of the three groups were compared...

The aim of this study was to determine serum levels of natriuretic peptide precursors (NT-proANP and NT-proBNP) during pregnancy in brachycephalic bitches. Fifteen healthy multiparous bitches were selected for this prospective study. Serum levels of NT-proANP and NT-proBNP were measured during anoestrous and at 14, 35, 42, 49 and 56 days (2nd, 5th, 6th, 7th and 8th weeks) of pregnancy. Fourteen animals had normal gestations, and one bitch developed single foetus syndrome. The natriuretic peptide levels of this animal were not included in this study; however, it is important to report that its NT-proANP levels were four times greater than those of normal patients...
