BACKGROUND In the acute phase of myocardial infarction (acute MI) marked endothelial damage occurs within the first 24h following thrombolysis with streptokinase. We investigated whether this is associated with a change in levels of vascular endothelial growth factor (VEGF, possibly marking angiogenesis) in the first 24h post thrombolysis compared to chronic MI patients (defined as MI>3 months ...

Background: Women with hypertensive disorders of pregnancy (HDP) have a significantly higher risk developing cardiovascular diseases later in life. The stratification this using biomarkers during can help to identify these women and apply early prevention. Objective: We aimed determine proinflammatory cytokines angiogenic markers, echocardiographic parameter changes after delivery predict disea...

Activating angiotensin II type 1 autoantibodies (AT1-AAs) develop in women with preeclampsia and may contribute to the disorder. Insulin resistance and serum concentrations of the antiangiogenic soluble fms-like tyrosine kinase 1 (sFlt-1) are also increased in women with preeclampsia compared with normal pregnancy. sFlt-1 and insulin resistance decrease substantially after delivery; however, si...

Reduced placental growth factor (PlGF) levels and higher soluble fms-like tyrosine kinase (sFlt-1) levels in mothers during pregnancy may have persistent effects on vascular structures in their offspring. We examined whether angiogenic factors during pregnancy also affect childhood retinal microvasculature in a population-based prospective cohort study among 3505 mothers and their children. We ...

OBJECTIVE The Elecsys(®) immunoassay sFlt-1/PlGF ratio and the Triage(®) PlGF assay were compared (in a prospective, multicenter, case-control study) for diagnosis of preeclampsia/hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome. METHODS Women in European perinatal care centers with singleton pregnancies were enrolled: 178 cases had confirmed preeclampsia and 391 controls had...

OBJECTIVE To investigate the potential value of combined screening by maternal characteristics and medical history (maternal factors), estimated fetal weight (EFW), uterine artery pulsatility index (UtA-PI), mean arterial pressure (MAP) and serum levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) at 30-34 weeks' gestation in the prediction of delivery of sm...

We previously isolated a novel tyrosine kinase receptor, Flt-1, now known as VEGF-receptor (VEGFR)-1. The VEGF-VEGFR system plays a pivotal role in not only physiological but also pathological angiogenesis. We examined the role of Flt-1 in carcinogenesis using Flt-1-signal-deficient (Flt-1 TK-/-) mice, and found that this receptor stimulates tumor growth and metastasis most likely via macrophag...

Pre-eclampsia is a hypertensive disorder of pregnancy initiated by placental insufficiency and chronic ischemia. In response, several pathways activated in the placenta are responsible for the maternal syndrome, including increased production of the anti-angiogenic protein, sFlt-1, and inflammatory cytokines, especially tumor necrosis factor-alpha (TNF-α). Previous studies have demonstrated tha...

The aim of this study was to quantify and localize the mRNA expression of the vascular endothelial growth factor (VEGF) receptors Flt1, KDR and sflt, in human endometrium throughout the menstrual cycle. Since neoangiogenesis is crucial during embryonic implantation, we postulate that endometrial receptivity to VEGF may be altered during the luteal phase in order to support implantation. Human e...

The pathogenesis and aetiology of pre-eclampsia (PE) is still unclear. We investigated the role of angiogenic, antiangiogenic and vasoactive factors in black South African women with early- and late-onset PE. Serum soluble fms-like tyrosine kinase 1 (sFlt-1), soluble vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) levels were determined using the ELISA technique, an...
