Filter by:The goal of this prospective cohort study is to investigate cardiac comorbidity in a random sample of approximately 1200 patients from a population of outpatients with rheumatoid arthritis and axial spondyloarthritis referred to collectively as inflammatory arthritis (IA). The main questions it aims to answer are: - Using conventional echocardiography, the investigators aim to determine the prevalence of overt and asymptomatic cardiac dysfunction in a large random sample of outpatients with IA. Cardiac dysfunction will be evaluated by echocardiography and cardiac biomarkers (NT-pro-BNP, hs-TNT and hs-CRP). - In patients without known heart disease: Using 2, 5 and 10 year follow-up, the investigators aim to examine if advanced echocardiography can be used to detect early signs of heart disease by investigating the clinical significance of adding deformation measures - alone and in combination with selected biomarkers - to conventional risk factors in the cardiac risk assessment of patients with IA Participants will undergo an echocardiographic examination in combination with a general health assessment including obtainment of cardiac biomarkers and a electrocardiogram. Using advanced echocardiography - Tissue Doppler Imaging, 2- dimensional speckle tracking echocardiography, 3D-echocardiography and 3-dimensional speckle tracking echocardiography - the investigators also aim to compare myocardial deformation parameters of patients with IA to a gender and age matched control group without IA from the Copenhagen City Heart Study.
Conduction system pacing vs biventricular resynchronization therapy in systolic dysfunction and wide QRS (CONSYST-CRT randomized clinical trial) is a non-inferiority trial that aims to study the composite endpoint consisting of all-cause mortality, cardiac transplant, heart failure hospitalizations, and left ventricular ejection fraction (LVEF) improvement <5 points.
A multi-center, randomized, double-blind, placebo-controlled phase III clinical trial to evaluate the effect of injectable Neucardin on the heart function in male patients with NT-proBNP ≤ 1700 pg/ml and female patients with NT-proBNP ≤ 4000 pg/ml, NYHA II-III chronic systolic heart failure, and to confirm its efficacy and safety.
The investigators hypothesize that a gradual reduction in antihypertensive treatment in nursing home (NH) patients with low systolic blood pressure (SBP) can improve survival through a controlled increase in SBP and a decrease in secondary morbidity due to 'overmedication'. Accordingly, the investigators propose a randomized, case/control trial in NH patients ≥ 80 years with a SBP<130 mmHg with >1 anti-Htn drugs. This trial will consist of two parallel arms: the intervention arm will entail antihypertensive drug step-down, while the control arm will comprise the standard anti-hypertensive treatment.
TransitionCHF aims to recruit a unique cohort of patients with asymptomatic left ventricular dysfunction (NYHA I) to study the progression to symptomatic (>NYHA I) HF and to identify parameters/ biomarkers promoting and predicting the individual risk of transition. Results from TransitionCHF Cohort Study will inform and refine current treatment guidelines. The implementation of common patient data sets and biobanking standards will enable data and biomaterial sharing with other study groups of the German Center for Cardiovascular Research (DZHK). This study will set the standard for a unique DZHK heart failure database and Biobank for innovative preclinical and clinical trials.
Contemporary heart failure (HF) guidelines recommend insertion of a primary prevention implantable defibrillator (ICD) in patients with left ventricular ejection fraction less than 35% (LVEF < 35%) on maximally tolerated medical therapy. Nevertheless, there are a substantial number of HF patients who have LVEF>35% and hence do not qualify for ICD, who succumb to sudden cardiac death (SCD). At present our tools to reliably risk stratify these patients with mild-moderate systolic dysfunction (LVEF 36-50%) are poor. It is likely that these patients have ventricular scar and/or replacement fibrosis as a substrate for their malignant arrhythmia. Cardiovascular magnetic resonance imaging (CMR) can reliably identify and quantify both ventricular scar (seen in Ischaemic cardiomyopathy, ICM) and replacement myocardial fibrosis (seen in Non-Ischemic Cardiomyopathy, NICM). Methods/Design: A multi-centre randomised controlled trial in which 428 patients with mild-moderate left-ventricular systolic dysfunction (either ICM or NICM) and ventricular scar/fibrosis on cardiovascular magnetic resonance are randomized to either ICD or implantable loop recorder (ILR) insertion and are followed up until the last patient recruited has been in the study for 3 years. Potentially eligible patients will have a screening CMR and will be enrolled into the device arm of study based on the presence of any ventricular scar/fibrosis (CMR +). Patients who do not have ventricular scar/fibrosis will be followed up in an observational registry, and will not be randomised. In both the device and registry arms, we aim to enrol 700 patients in Australia and 355 in Europe. The primary hypothesis is that among patients with mild-moderate left ventricular systolic dysfunction, a routine CMR guided management strategy of ICD insertion is superior to a conservative strategy of standard care.
