Risk Factors of Coronary Artery Disease in Secondary Prevention—Results from the AtheroGene—Study

2015

Background Risk factors are important in cardiovascular (CV) medicine for risk stratification of patients. We aimed to compare the traditional risk factors to clinical variables for the prediction of secondary cardiovascular events. Methods and Results For this study, 3229 patients with known coronary artery disease (CAD) were included. We calculated whether the traditional risk factors, diabetes mellitus, increased LDL/HDL ratio, arterial hypertension and smoking alone and in combination with the clinical variables, ejection fraction, creatinine clearance, multi-vessel disease and CRP concentration predict the outcome cardiovascular death or non-fatal myocardial infarction (N = 432) during…

Impact of Proportionality of Secondary Mitral Regurgitation on Outcome After Transcatheter Mitral Valve Repair

2020

The purpose of this paper was to evaluate the impact of proportionality of secondary mitral regurgitation (SMR) in a large real-world registry of transcatheter edge-to-edge mitral valve repair (TMVr) BACKGROUND: Differences in the outcomes of recent randomized trials of TMVr for SMR may be explained by the proportionality of SMR severity to left ventricular (LV) volume.The ratio of pre-procedural effective regurgitant orifice area (EROA) to LV end-diastolic volume (LVEDV) was retrospectively assessed in patients undergoing TMVr for severe SMR between 2008 and 2019 from the EuroSMR registry. A recently proposed SMR proportionality scheme was adapted to stratify patients according to EROA/LVE…

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…

Impact of Right Ventricular Dysfunction on Outcomes After Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation

2021

OBJECTIVES This study sought to assess the impact of right ventricular dysfunction (RVD) as defined by impaired right ventricular-to-pulmonary artery (RV-PA) coupling, on survival after edge-to-edge transcatheter mitral valve repair (TMVR) for severe secondary mitral regurgitation (SMR). BACKGROUND Conflicting data exist regarding the benefit of TMVR in severe SMR. A possible explanation could be differences in RVD. METHODS Using data from the EuroSMR (European Registry on Outcomes in Secondary Mitral Regurgitation) registry, this study compared the characteristics and outcomes of SMR patients undergoing TMVR, according to their RV-PA coupling, assessed by tricuspid annular plane systolic e…

Homocysteine concentration in coronary artery disease: Influence of three common single nucleotide polymorphisms.

2017

Whether single nucleotide polymorphisms (SNPs) of homocysteine metabolism enzymes influence the rate of cardiovascular (CV) events in coronary artery disease (CAD) patients remains controversial.In this analysis, 1126 subjects from the AtheroGene study with CAD and 332 control subjects without known CAD were included. The following SNPs were investigated: methylentetrahydrofolate reductase (MTHFR-C667T), methionin synthetase (MS-D919G), and cystathionin beta synthetase (CBS-I278T). The endpoint was the combination of cardiovascular death, stroke, and non-fatal myocardial infarction (N = 286). The median follow-up time was 6.4 years. Kaplan-Meier curve analysis showed an increasing event rat…

Prognostic use of soluble fms-like tyrosine kinase-1 and placental growth factor in patients with coronary artery disease.

2015

Background: Intention of the study is to assess the cardiovascular mortality of patients with coronary artery disease (CAD) with the biomarkers of angiogenesis PlGF and its endogenous inhibitor sFlt-1. Methods: The cohort included n = 1848 patients with CAD and 282 subjects without CAD. In 85 patients cardiovascular mortality, as combination of fatal myocardial infarction or any cardiac death, during a median follow-up duration of 3.9 years was reported. Results: In Kaplan–Meier curve analysis PlGF in rising thirds was not predictive regarding outcome (p = 0.54), the same was shown for sFlt-1 (p = 0.44). Cox regression for the fully adjusted model provided a hazard ratio (HR) of 0.8 (p = 0…

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…

The utility of pregnancy-associated plasma protein A for determination of prognosis in a cohort of patients with coronary artery disease.

2015

Background: Pregnancy-associated plasma protein-A (PAPP-A) is discussed as a biomarker representing unstable plaques in coronary artery disease (CAD). Methods: In this study 927 patients with CAD (534 with stable angina and 393 with acute coronary syndrome [ACS]) and 217 patients without CAD and measured PAPP-A levels were included. Follow-up for a median of 5 years was documented. Results: Rising quartiles of PAPP-A concentration had a higher cardiovascular mortality in the overall cohort of patients with CAD (p = 0.002) and the cohort with ACS (p = 0.01). Patients with suspected ACS below the LOD for troponin I but elevated PAPP-A levels had an increased cardiovascular mortality. A cut-o…

Cardiovascular Mortality in Chest Pain Patients: Comparison of Natriuretic Peptides With Novel Biomarkers of Cardiovascular Stress.

2016

Natriuretic peptides are the standard biomarker for risk stratification in cardiovascular disease. Novel biomarkers of cardiovascular stress might allow refinement in risk stratification for patients with acute coronary syndrome (ACS). We tested the performance of these novel biomarkers for cardiovascular risk stratification in patients who presented with ACS.In the AtheroGene study, 873 patients presented with ACS in the emergency department. Biomarkers measured were: B-type natriuretic peptide (BNP), N-terminal pro BNP (NT-proBNP), midregional proatrial natriuretic peptide, midregional proadrenomedullin (MR-proADM), copeptin, and troponin I. The median follow-up time was 4 years and durin…

Relative Telomere Length and Cardiovascular Risk Factors

2019

(1) Background: Telomeres are repetitive DNA sequences located at the extremities of chromosomes that maintain genetic stability. Telomere biology is relevant to several human disorders and diseases, specifically cardiovascular disease. To better understand the link between cardiovascular disease and telomere length, we studied the effect of relative telomere length (RTL) on cardiovascular risk factors in a large population-based sample. (2) Methods: RTL was measured by a real-time quantitative polymerase chain reaction in subjects of the population-based Gutenberg Health Study (n = 4944). We then performed an association study of RTL with known cardiovascular risk factors of smoking status…
