China PEACE 5r-HF Study

Heart Failure

This study will use a two-stage random sampling design to create a nationally representative sample of patients with heart failure (HF) in China. The investigators sought to describe the clinical profiles, to assess treatment patterns and in-hospital outcomes for HF, and to identify targets for care quality improvement.

Follow-up of GANI_MED Cardio Cohorts

Chronic Heart FailureMetabolic Syndrome

Follow-up of two hospital-based patient cohorts (heart failure, metabolic comorbidities in CVD), recruited at baseline by the GANI_MED-project (Greifswald Approach to Individualized Medicine). Standardized protocols will be used for the assessment of medical history, laboratory biomarkers, and the collection of various biosamples for bio-banking purposes. Comparisons with the general background population will be performed.

Serial Multiparametric Evaluation of Right Ventricular Function After Left Ventricular Assist Device...

Right Heart Failure

The primary purpose of this study is to investigate the evolution of Right Ventricular (RV) function before and after left ventricular assist device (LVAD) implantation, using novel echocardiographic quantification of RV size and function in combination with comprehensive hemodynamic, laboratory and clinical parameters. The findings of the study will enhance prediction of early and late development of postoperative right-sided heart failure (RHF) and subsequent mortality and morbidity. The secondary purpose of the study is to combine echocardiographic, hemodynamic, laboratory, and clinical data to define optimal management strategies of RHF after LVAD implantation.

Ischemic Heart FailureLipids3 more

Current prospective cohort study is to evaluate the association between fasting lipid profiles (including total cholesterol, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, triglycerides, apolipoprotein A, apolipoprotein B and lipoprotein(a)) and fasting plasma glucose at admission with cardiovascular disease outcomes (including fatal and non-fatal myocardial infarction, fatal and non-fatal ischemic stroke, re-hospitalization due to heart failure, revascularization by percutaneous coronary intervention or coronary artery bypass grafting, or cardiovascular mortality) and all-cause mortality.in patients with ischemic heart failure and left ventricular ejection fraction < 45 % evaluated by echocardiography during 12 months follow-up.

Speckle Tracking Imaging and Realtime 3 Dimensional Echocardiograhy to Study LV Function and Remodeling...

Congestive Heart FailureMitral Regurgitation

Left ventricular (LV) remodeling after acute myocardial infarction (AMI) has been well described in previous studies. However, there is a paucity of data on the incidence of and risk factors for LV remodeling in modern clinical practice that incorporates widespread use of acute reperfusion strategies and almost systematic use of "antiremodeling" medications, such as angiotensin-converting enzyme inhibitors and beta blockers. The recent improvements in AMI management do not abolish LV remodeling, which remains a relatively frequent event after an initial anterior wall AMI. As a leading cause of heart failure, postinfarction LV remodeling represents an important target for therapeutic interventions. Within the ventricular mass, size, shape, connections and orientation in a three-dimensional space of every single constituent determine its functional behavior. The complex architecture of the ventricular mass creates multiple inhomogeneities of electrical and mechanical loads at the cellular and the microscopic tissue level, that cause cardiac function to be 'stochastic in nature'. The myocardial infarction will altered the ventricular shape and functional inhomogeneities carrying the morphodynamic advantages such as impaired suction for diastole after diminishing recoil relaxation with decreased twisting strain in systole. The alteration in contractile mechanics interacts with the intraventricular fluid dynamic filed that influence the regional myocardial shearing stress. Altered LV transmural wall strains have been proposed to cause infarct extension and may have an important role in propagating LV remodeling.

Vascular Sensitivity to Adrenergic Agonists in Patients With CHF and in Healthy Subjects

Congestive Heart Failure

Congestive Heart failure (CHF) is asociated with changes in cardiac function and vascular responses. The aim of this study is to characterize these differences. Our hypothesis is, that there are differences in vascular responses between healthy subjects and patients with CHF.

Does Lung Impedance Correlate With Changes in BNP in Stable and Acutely Decompensated Heart Failure...

Congestive Heart Failure

The purpose of this study is to determine whether there is a relationship between serial B-natriuretic peptide (BNP) and implantable device measured intrathoracic impedance in symptomatic and asymptomatic heart failure patients over a 1-year period. Furthermore, this study will establish whether implantable device measured intrathoracic impedance trends with the distance walked on a six-minute hall walk (6MHW), an exercise-based acute measure that has also been associated with heart failure clinical status.

Optimization of Cardiac Pacing Using CardioMEMS

Heart Failure

This study is designed to determine if a simplified technique for cardiac device reprogramming using pulmonary artery pressure (PAP) data in the acute setting holds promise to improve subjective assessments of patient quality of life (QOL), objective measurements of functional capacity, and specific systolic and diastolic echocardiographic indices.
