CA125 outperforms NT-proBNP in acute heart failure with severe tricuspid regurgitation.
2019
In acute heart failure (AHF) with right ventricular dysfunction, the roles of amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) are poorly understood, and functional tricuspid regurgitation (TR) severity is thought to indicate a poor prognosis. We examined the prognostic abilities of NT-proBNP and CA125 according to TR status among patients with AHF.TR severity was assessed during index hospitalization (108 ± 24 h after admission) and classified as none/trivial, mild, moderate, or severe. Multivariable Cox regression analysis was performed to assess how pre-discharge CA125 and NT-proBNP were associated with long-term all-cause mortality relative t…
TET2 gene mutation is a frequent and adverse event in chronic myelomonocytic leukemia
2009
Background Acquired somatic deletions and loss-of-function mutations in one or several codons of the TET2 ( Ten-Eleven Translocation-2 ) gene were recently identified in hematopoietic cells from patients with myeloid malignancies, including myeloproliferative disorders and myelodys-plastic syndromes. The present study was designed to determine the prevalence of TET2 gene alterations in chronic myelomonocytic leukemias. Design and Methods Blood and bone marrow cells were collected from 88 patients with chronic phase chronic myelomonocytic leukemia and from 14 with acute transformation of a previously identified disease. Polymerase chain reaction analysis and direct sequencing were used to se…
Osteoarthritis Increases the Risk of Cardiovascular Disease: Data from the Osteoarthritis Initiative
2018
Objectives: Although osteoarthritis (OA) is a common condition in older adults, the role of OA in increasing cardiovascular disease (CVD) incidence is still debated. The aim of this study was to investigate the association between OA and the onset of CVD in a large database of American adults. Design: Longitudinal. Setting: Community-dwelling. Participants: People with OA or at high risk of OA. Measurements: Osteoarthritis was defined as the presence of OA of the hand, knee, hip, back/neck or of other sites. CVD was defined as self-reported presence of heart attack, heart failure, stroke and other cerebral atherosclerotic conditions, and peripheral artery disease. Results: A total 4,265 per…
PLTP activity is a risk factor for subsequent cardiovascular events in CAD patients under statin therapy: the AtheroGene study.
2009
Phospholipid transferprotein (PLTP) mediates both net transfer and exchange of phospholipids between different lipoproteins. Although many studies have investigated the role of PLTP in atherogenesis, the role of PLTP in atherosclerotic diseases is unclear. We investigated the association of serum PLTP activity with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) and its relation to other markers of atherosclerosis in 1,085 patients with angiographically documented coronary artery disease (CAD). In the median follow-up of 5.1 years, 156 patients had suffered from the combined endpoint of myocardial infarction or cardiovascular death including 47 of 395 p…
Impact of asymmetric dimethylarginine on mortality after acute myocardial infarction.
2008
Objective— Asymmetrical dimethylarginine (ADMA) is an endogenous competitive inhibitor of nitric oxide (NO) synthases. From a prospective cohort of patients with acute myocardial infarction (MI), we aimed to analyze the predictive value of circulating ADMA concentrations on prognosis. Methods and Results— Blood samples from 249 consecutive patients hospitalized for acute MI <24 hours were taken on admission. Serum levels of ADMA and its stereoisomer, symmetrical dimethylarginine (SDMA), were determined using high-performance liquid chromatography. The independent predictors of ADMA were glomerular filtration rate, female sex, and SDMA ( R 2 =0. 25). Baseline ADMA levels were higher in p…
Usefulness of C-reactive protein and left ventricular function for risk assessment in survivors of acute myocardial infarction.
2004
The additional prognostic information provided by C-reactive protein (CRP) to parameters of left ventricular function in survivors of acute myocardial infarction (AMI) was investigated in 665 patients (326 with ST elevation and 339 with non-ST elevation). Cox multivariable analysis identified the following predictors of 6-month cardiac death: age (per 5 years hazard ratio [HR] 1.2, 95% confidence interval [CI] 1.1 to 1.4, p = 0.004), Killip class >I at presentation (HR 2.4, 95% CI 1.3 to 4.5, p = 0.0001), a reduced ejection fraction (per 5% HR 1.3, 95% CI 1.2 to 1.4, p = 0.0001), and greater CRP (per 5 mg/L HR 1.02, 95% CI 1.01 to 1.04, p = 0.02); the C-index of the model was 0.77 without a…
Long-term prognostic value of a comprehensive assessment of cardiac magnetic resonance indexes after an ST-segment elevation myocardial infarction.
2013
Abstract Introduction and objectives A variety of cardiac magnetic resonance indexes predict mid-term prognosis in ST-segment elevation myocardial infarction patients. The extent of transmural necrosis permits simple and accurate prediction of systolic recovery. However, its long-term prognostic value beyond a comprehensive clinical and cardiac magnetic resonance evaluation is unknown. We hypothesized that a simple semiquantitative assessment of the extent of transmural necrosis is the best resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction. Methods One week after a first ST-segment elevation myocardial infarction we carried out a comp…
Prognostic Value of Myocardial Ischemia and Necrosis in Depressed Left Ventricular Function: a Multicenter Stress Cardiac Magnetic Resonance Registry
2013
A B S T R A C T Introduction and objectives: The incremental prognostic value of inducible myocardial ischemia over necrosis derived by stress cardiac magnetic resonance in depressed left ventricular function is unknown. We determined the prognostic value of necrosis and ischemia in patients with depressed left ventricular function referred for dipyridamole stress perfusion magnetic resonance. Methods: In a multicenter registry using stress magnetic resonance, the presence ( 2 segments) of late enhancement and perfusion defects and their association with major events (cardiac death and nonfatal infarction) was determined. Results: In 391 patients, perfusion defect or late enhancement were p…
Case Control Study of Neuroblastoma in West-Germany after the Chernobyl Accident
1996
Background To explore possible causes of a 1988 incidence peak of infant neuroblastoma in west German regions which were contaminated with more than 6000 Bq/m2 Cs137 from the Chernobyl accident. The primary working hypothesis was that parents of the diseased children had been contaminated by an excessive intake of locally produced food, especially mushrooms or deer. Design Case control study with 1:2 (cases:controls) matching. Data were collected from the children's parents by questionnaires and telephone interviews. Setting Nation-wide study (former FRG) based on the German Childhood Cancer Registry. Subjects Cases born in 1988 and reported with a neuroblastoma to the registry until March …
Long-term clinical outcomes after drug-eluting stent implantation in unprotected left main coronary artery disease.
2009
Objective: To investigate long-term outcomes of unprotected left main coronary artery (ULMCA) disease treatment using drug-eluting stents (DES). Background: In several studies, DES implantation in ULMCA appeared safe and effective at mid-term; however, to date, there is limited long-term data. Methods: All consecutive patients undergoing sirolimus- or paclitaxel-eluting stent implantation in ULMCA disease at a single institution were evaluated. The primary endpoint was long-term major adverse cardiac events (MACE) defined as cardiac death, nonfatal myocardial infarction, or target lesion revascularization (TLR). Stent thrombosis (ST), according to Academic Research Consortium definitions, w…
