Background: Venous thromboembolism is a frequent complication and an important cause of death in patients with paralysis. We aimed to investigate predictors of pulmonary embolism (PE) and the impact of PE on the survival of patients with paralysis in comparison to those with deep venous thrombosis or thrombophlebitis (DVT).

Methods: Patients were selected by screening the German nationwide inpatient sample (2005-2017) for paralysis, and were stratified for venous thromboembolism (VTE) and the VTE-sub-entity PE (ICD-code I26).

Background: Venous thromboembolism (VTE) constitute a major global burden of disease. Current international guidelines recommend treatment with anticoagulant therapy after VTE for a duration of at least 3 months. Since anticoagulation also imposes an increased risk for bleeding events, the individual risk has to be evaluated to determine adequate treatment plans.

Background: Pulmonary embolism (PE) is a frequent complication in immobile stroke patients and an important cause of death in stroke patients. We aimed to investigate predictors of PE and the impact of PE on survival of ischemic stroke patients.

Methods: Patients were selected by screening the German nationwide inpatient sample (2005-2017) for ischemic stroke (ICD-code I63) and stratified for occurrence of PE (ICD-code I26).

Aims: Nighttime aircraft noise exposure has been associated with increased risk of hypertension and myocardial infarction, mechanistically linked to sleep disturbance, stress, and endothelial dysfunction. It is unclear, whether the most widely used metric to determine noise exposure, equivalent continuous sound level (Leq), is an adequate indicator of the cardiovascular impact induced by different noise patterns.

Methods And Results: In a randomized crossover study, we exposed 70 individuals with established cardiovascular disease or increased cardiovascular risk to two aircraft noise scenarios and one control scenario.

Background And Aim: The number of percutaneous edge-to-edge mitral regurgitation (MR) valve repairs with MitraClip® implantations increased exponentially in recent years. Studies have suggested an obesity survival paradox in patients with cardiovascular diseases. We investigated the influence of obesity on adverse in-hospital outcomes in patients with MitraClip® implantation.

Background: Pulmonary embolism (PE) is a frequent cause of death and morbidity. A few studies suggest that clot burden in pulmonary artery bed is related to PE patients' survival, but the impact of concomitant deep venous thrombosis and/or thrombophlebitis (DVT) on short-term survival of PE patients remains unclear. Thus, we aimed to investigate the impact of DVT on adverse outcomes in PE patients.

Background: Despite remarkable improvements in treatment of cardiovascular disease, heart failure (HF) is still characterized by high mortality rate. Sex-specific differences in HF have been described, but underlying reasons are widely unexplored.

Methods: The nationwide German inpatient sample (2005-2016) was used for this sex-specific analyses.

Background: Stroke is the second leading cause of death worldwide. Ischemic strokes, which are caused by atrial fibrillation/flutter (AF), may be more devastating than those that occur without AF.

Objective: The purpose of this study was to investigate the impact of AF on adverse events in hospitalized ischemic stroke patients and to estimate the elevated impact of AF on the occurrence of these adverse events.

Objective: To investigate the impact of obesity and underweight on adverse in-hospital outcomes in pulmonary embolism (PE).

Patients And Methods: Patients diagnosed as having PE based on International Statistical Classification of Diseases and Related Health Problems, 10th Revision, German Modification code I26 in the German nationwide inpatient database were stratified for obesity, underweight, and normal weight/overweight (reference group) and compared regarding adverse in-hospital outcomes.

Results: From January 1, 2011, through December 31, 2014, 345,831 inpatients (53.

Objectives: The aim of this study was to evaluate 5-year in-hospital trends and safety outcomes of left atrial appendage (LAA) closure in the German nationwide inpatient sample.

Background: The safety and efficacy of percutaneous LAA closure have been demonstrated in randomized trials and prospective cohort studies, but results from large samples are missing.

Methods: Data on patient characteristics and in-hospital safety outcomes for all percutaneous LAA closures performed in Germany between 2011 and 2015 were analyzed.

Background: Seasonal variation regarding the incidence and the short-term mortality of acute myocardial infarction (MI) was frequently reported, but data about sex-specific differences are sparse.

Methods: We analysed the impact of seasons and temperature on incidence and in-hospital mortality of patients with acute MI in Germany between 2005 and 2015.

Results: The nationwide sample comprised 3,008,188 hospitalizations of MI patients (2005-2015).

Aims: Syncope is a common phenomenon in the general population. Although most of the causes are of benign origin, some comorbidities are accompanied by high mortality. We aimed to compare the in-hospital mortality of patients with syncope related to different comorbities and investigate the impact of syncope in patients with atrial fibrillation/flutter (AF).

Introduction: Chronic Hepatitis C virus infection (HCV) is associated with extrahepatic manifestations and an increased prevalence in cardiovascular disease. New direct acting antivirals (DAA) have revolutionized HCV treatment with high rates of sustained virological response (SVR). Recently it was demonstrated, that SVR reduces morbidity and overall mortality more than can be solely explained by hepatic effects, suggesting that treatment with DAA also affects cardiovascular disease.
