Background Risk stratification among patients with coronary artery disease ( CAD ) is of considerable interest due to the potential to guide secondary preventive therapies. Thus, we evaluated the predictive value of soluble urokinase‐type plasminogen activator receptor (su PAR ) levels for cardiovascular mortality and nonfatal myocardial infarction in patients with CAD . Methods and Results Plasma levels of su PAR were measured in a cohort of 1703 patients with documented CAD as evidenced by coronary angiography—including 626 patients with acute coronary syndrome and 1077 patients with stable angina pectoris. Cardiovascular death and/or nonfatal myocardial infarction were defined as main o…
Diagnostic and prognostic performance of myeloperoxidase plasma levels compared with sensitive troponins in patients admitted with acute onset chest …
2012
Background— Activation of leukocytes with release of myeloperoxidase (MPO) has been linked to acute coronary disease. To date, studies investigating the diagnostic and prognostic performance of circulating MPO in patients with chest pain (CP) are mainly retrospective, of low size, and lack a cut-off value for MPO. Herein, we prospectively assess the diagnostic and prognostic properties of MPO compared with sensitive troponin I (sTNI) in patients admitted to the emergency room with CP. Methods and Results— One thousand, eight hundred and eighteen consecutive patients (mean age, 61.4±13.5 years; 33.6% female) admitted for CP underwent determination of MPO, sTnI, and B-natriuretic peptide pla…
Relations of Sex to Diagnosis and Outcomes in Acute Coronary Syndrome
2018
Background The atypical presentation of women with acute coronary syndrome ( ACS ) has been related to delayed diagnosis and treatment, which may explain worse outcome compared with men. Methods and Results We analyzed pooled data of 2520 patients of 2 prospective cohorts in terms of differences in presentation and management of women and men suggestive of ACS . Using logistic regression, we established 2 diagnostic models and tested their diagnostic performance in both sexes separately. Sex‐specific differences in management of patients with ACS were ascertained and a 2‐year follow‐up was performed. Women were older than men (median 67 versus 61 years, P =0.001), had more often dyspnea (2…
Head-to-Head Comparison of the Incremental Predictive Value of The Three Established Risk Markers, Hs-troponin I, C-Reactive Protein, and NT-proBNP, …
2020
Risk stratification among patients with coronary artery disease (CAD) is of considerable interest to potentially guide secondary preventive therapies. Cardiac troponins as well as C-reactive protein (hsCRP) and natriuretic peptides have emerged as biomarkers for risk stratification. The question remains if one of these biomarkers is superior in predicting adverse outcomes. Thus, we perform a head-to-head comparison between high-sensitivity troponin I (hsTnI), hsCRP, and N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with CAD. Plasma levels were measured in a cohort of 2193 patients with documented CAD. The main outcome measures were cardiovascular (CV) death and/or nonfata…
Assessment of microRNAs in patients with unstable angina pectoris.
2014
Aims While cardiac troponin measurements have significantly improved the early diagnosis of myocardial infarction, the timely biomarker-based diagnosis of unstable angina pectoris (UAP) remains a major unmet clinical challenge. The aim of this study was to assess levels of circulating microRNAs (miRNAs) as possible novel biomarkers in patients with UAP. Methods and results A three-phase approach was conducted, comprising (i) profiling of miRNAs in patients with UAP and controls groups; (ii) replication of significant miRNAs in an independent patient cohort, (iii) validation of a multi-miRNAs panel in a third cohort. Out of 25 miRNAs selected for replication, 8 miRNAs remained significantly …
ADMA and arginine derivatives in relation to non-invasive vascular function in the general population.
2015
Nitric oxide produced from l-arginine is central to vascular homeostasis. Little is known about the relationship between arginine derivatives including asymmetric dimethylarginine (ADMA) and non-invasive vascular function measures in the general population.In 5000 individuals (median age 56; 25th/75th percentile: 46, 65; 49% women) taking part in the population-based Gutenberg Health Study (Mainz area, Germany), we measured the relationship between the arginine derivatives asymmetric dimethylarginine (ADMA), N-monomethyl l-arginine (NMMA), symmetric dimethylarginine (SDMA) and l-arginine with flow-mediated dilation (FMD) and peripheral arterial tonometry (PAT). Weak bivariate correlations w…

Homoarginine Levels are Regulated by L-Arginine: Glycine Amidinotransferase and Affect Stroke Outcome: Results from Human and Murine Studies
2013
Background— Endogenous arginine homologues, including homoarginine, have been identified as novel biomarkers for cardiovascular disease and outcomes. Our studies of human cohorts and a confirmatory murine model associated the arginine homologue homoarginine and its metabolism with stroke pathology and outcome. Methods and Results— Increasing homoarginine levels were independently associated with a reduction in all-cause mortality in patients with ischemic stroke (7.4 years of follow-up; hazard ratio for 1-SD homoarginine, 0.79 [95% confidence interval, 0.64–0.96]; P =0.019; n=389). Homoarginine was also independently associated with the National Institutes of Health Stroke Scale+age score …

Background: Pulmonary disease has consistently been related to increased mortality. We investigated central spirometry variables in relation to total mortality in individuals from the general population without diagnosed lung disease also accounting for cardiac function. Methods: In 15,010 individuals from the general population (mean age 55±11 years, age range 35-74 years, 50.5% men) in the Gutenberg Health Study we performed spirometry and multimodal transthoracic echocardiography. The biomarkers N-terminal pro-B-type natriuretic peptide (Nt-proBNP) and high-sensitive troponin I (TnI) were measured in the first 5000 individuals using commercially available assays. Multivariable Cox regre…
Biomarkers for characterization of heart failure - Distinction of heart failure with preserved and reduced ejection fraction.
2016
Heart failure (HF) incidence is rising worldwide and HF with preserved ejection fraction (HFpEF) represents nearly half of all cases. Treatment options are still limited in HFpEF in comparison to HF with reduced ejection fraction (HFrEF).We analyzed biomarkers in the general population to characterize HFpEF and HFrEF and defined a biomarker index to differentiate HFpEF from HFrEF. Growth differentiation factor-15 (GDF-15), soluble source of tumorigenicity 2 (sST2), C-reactive protein (CRP) and NT-proBNP were measured in 5000 individuals of the population-based Gutenberg Health Study (GHS). The median follow-up time for all-cause mortality was 7.3years with 213 events.Identification of subje…

2017
Background Microvascular dysfunction is a marker of early vascular disease that predicts cardiovascular events. Whether metabolically healthy obese individuals have impaired microvascular function remains unclear. The aim of this study was to evaluate the relation of obesity phenotypes stratified by metabolic status to microvascular function. Methods and Results We meta‐analyzed aggregate data from 3 large cohorts (Brazilian Longitudinal Study of Adult Health, the Framingham Heart Study, and the Gutenberg Heart Study; n=16 830 participants, age range 19–90, 51.3% men). Regression slopes between cardiovascular risk factors and microvascular function, measured by peripheral arterial tonometr…
Subclinical impairment of lung function is related to mild cardiac dysfunction and manifest heart failure in the general population.
2016
Lung function impairment has previously been related to heart failure, although no overt cardiovascular or structural heart disease is present. The extent to which pulmonary function is related to subclinical left ventricular impairment in the general population remains to be investigated.15010 individuals from the general population (mean age 55±11years, 50.5% men) in the Gutenberg Health Study underwent spirometry, transthoracic echocardiography and biomarker measurement. Forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC) in percent of the predicted value and FEV1/FVC ratio were associated with echocardiographic measures of cardiac structure, systolic and diastolic func…

2010
ObjectivesEarly identification of myocardial infarction in chest pain patients is crucial to identify patients at risk and to maintain a fast treatment initiation.BackgroundThe aim of the current investigation is to test whether determination of copeptin, an indirect marker for arginin-vasopressin, adds diagnostic information to cardiac troponin in early evaluation of patients with suspected myocardial infarction.MethodsBetween January 2007 and July 2008, patients with suspected acute coronary syndrome were consecutively enrolled in this multicenter study. Copeptin, troponin T (TnT), myoglobin, and creatine kinase-myocardial band were determined at admission and after 3 and 6 h.ResultsOf 1,…
Cross-Sectional Associations between Homoarginine, Intermediate Phenotypes, and Atrial Fibrillation in the Community—The Gutenberg Health Study
2018
Homoarginine has come into the focus of interest as a biomarker for cardiovascular disease. Atrial fibrillation (AF) causes a substantial increase in morbidity and mortality. Whether circulating homoarginine is associated with occurrence or persistence of AF and may serve as a new predictive biomarker remains unknown. We measured plasma levels of homoarginine in the population-based Gutenberg health study (3761 patients included, of them 51.7% males), mean age 55.6 ±
Transcriptome-Wide Analysis Identifies Novel Associations With Blood Pressure.
2017
Hypertension represents a major cardiovascular risk factor. The pathophysiology of increased blood pressure (BP) is not yet completely understood. Transcriptome profiling offers possibilities to uncover genetics effects on BP. Based on 2 populations including 2549 individuals, a meta-analyses of monocytic transcriptome-wide profiles were performed to identify transcripts associated with BP. Replication was performed in 2 independent studies of whole-blood transcriptome data including 1990 individuals. For identified candidate genes, a direct link between long-term changes in BP and gene expression over time and by treatment with BP-lowering therapy was assessed. The predictive value of pro…
Atrial Fibrillation Manifestations Risk Factors and Sex Differences in a Population-Based Cohort (From the Gutenberg Health Study)
2018
Sex differences in cardiovascular risk factors, cardiac structure and function, and disease and symptom burden in the common arrhythmia atrial fibrillation (AF) have not been investigated systematically at the population level. Cross-sectional data of 14,796 subjects (age range 35 to 74 years, 50.5% men) from the population-based Gutenberg Health Study were examined to show the distribution of cardiovascular risk factors by AF status and sex, and to determine sex-specific predictors for AF. The prevalence of AF was higher in men (4.3%) than in women (1.9%). Men had a worse cardiovascular risk factor profile, a higher prevalence of cardiovascular disease, but fewer symptoms than women. Age-a…

2019
Background Arterial stiffness is a strong predictor of atrial fibrillation in the community. Whether noninvasively measured conduit artery function and peripheral vascular reactivity are related to atrial fibrillation remains unknown. Methods and results In 15 010 individuals of the population-based Gutenberg Health Study, mean age 55 ± 11 years, 50.5% men, we determined noninvasive vascular function by flow-mediated dilation (FMD) and peripheral arterial tonometry (PAT) in relation to manifest atrial fibrillation (N = 466). Patients with atrial fibrillation exhibited a higher mean brachial artery diameter [4.81 mm (4.17, 5.33) in atrial fibrillation vs. 4.31 mm (3.67, 4.93)] and baseline p…
Genome-wide and gene-centric analyses of circulating myeloperoxidase levels in the charge and care consortia
2013
Increased systemic levels of myeloperoxidase (MPO) are associated with the risk of coronary artery disease (CAD). To identify the genetic factors that are associated with circulating MPO levels, we carried out a genome-wide association study (GWAS) and a gene-centric analysis in subjects of European ancestry and African Americans (AAs). A locus on chromosome 1q31.1 containing the complement factor H (CFH) gene was strongly associated with serum MPO levels in 9305 subjects of European ancestry (lead SNP rs800292; P = 4.89 × 10(-41)) and in 1690 AA subjects (rs505102; P = 1.05 × 10(-8)). Gene-centric analyses in 8335 subjects of European ancestry additionally identified two rare M…
Gender-specific diagnostic performance of a new high-sensitivity cardiac troponin I assay for detection of acute myocardial infarction.
2016
The determination of cardiac troponin is essential for diagnosing myocardial infarction. A troponin I assay has recently been developed that provides the highest analytical sensitivity to date.The analysis included 1560 patients with chest pain, of whom 1098 were diagnosed with non-coronary chest pain, 189 with unstable angina pectoris and 273 with non-ST-segment elevation myocardial infarction. The troponin I concentration was determined on admission (0 hours) and 3 hours later. The diagnostic algorithm incorporated troponin I elevation above the gender-specific 99th percentile as well as predefined relative or absolute 3-hour changes in the troponin I concentration (delta).The diagnostic …

2011
Abstract Background The purposes of this paper are to determine the prevalence of distress in the community, to identify its determinants and to assess its relationship to somatic conditions and subjective well being. Methods Distress and associated factors were investigated in a random sample of 5000 participants (35–74 years) of a community-based, prospective, observational cohort study in western Mid-Germany (“Gutenberg Heart Study”) between 04/2007 and 10/2008. The sample was stratified 1:1 for gender and residence and in equal strata for decades of age. Data were assessed by self-report instruments, interviews and medical examination. Results We found a prevalence rate for depression o…
Defining a reference population to determine the 99th percentile of a contemporary sensitive cardiac troponin I assay
2013
Abstract Background Diagnosis of acute myocardial infarction (AMI) according to the universal definition is based on ischemic symptoms, imaging findings and elevated myocardial necrosis markers, preferably cardiac troponin I/T with diagnostic threshold representing the 99th percentile of a reference population. It is not clearly defined if this should be an unselected population-based or a healthy cohort with respect to cardiac diseases. Aim of the current study was to describe the distribution of troponin I using a sensitive assay and to evaluate the impact of cardiac diseases and cardiovascular risk factors in apparently healthy individuals. Methods Troponin I was determined using a conte…
