Active clinical trials for "Heart Failure"

A prospective randomized controlled trial studying the ordering of palliative care consultations in the emergency department (Ig) versus later palliative care consultations in the hospital--ICU or hospital ward(Cg). Patients will be randomly allocated to Ig or Cg with a 1:1 ratio.

The purpose of this study is examine whether invasive pulmonary artery pressure (PAP) monitoring could be beneficial for the patients in dialysis treatment. Ten implantable pressure sensors (CardioMEMS ®) will be implanted and the PAPs of the individual participants are recorded during and in between the routine dialysis treatment sessions. This is an exploratory pilot study, where major interest lies in the values and changes in PAP in relation to other hemodynamic parameters among patients in dialysis treatment. Implanted device is only monitoring the patient without any effect on the actual treatment.

Burden of HF in India is approximate 2-5 million patients with an estimated prevalence of 2-3/1000 population. HF is responsible for approx1.8 million admissions annually in India. Very few studies are there in India which shows the detailed documentation of HF. Manipal Heart failure Registry (MHFR) is an institutional level Heart Failure disease registry. In MHFR the investigator will document the detailed information about heart failure patients admitted or referred to Department of Cardiology, Kasturba Medical College, a constituent college and teaching hospital of Manipal University. MHFR will include cohorts of patients with acute heart failure (AHF), with the intention of implementing a long-term follow-up, the use of health economic assessment to evaluate the degree of resource utilization; and quantifying the burden on quality of life for patients. Utilization of drug in HF patients will be evaluated as a part of this study to prevent the use of inappropriate drug therapy and to improve overall drug effectiveness and outcomes. Hence the protocol sought to identify the characteristics and long-term outcomes of Indian patients with acute heart failure admitted in an Indian tertiary care center in South India. There are no risks to patients participating in the registry study, as standard of care quality will not be affected. It is unlikely that there will be any direct benefit as a result of participation in the HF-disease registry. However, the information contained within this non-interventional registry study will be used for research studies directed at improving the knowledge and treatment of acute heart failure as well as improving patients treatment in the future. The potential impact of proposed research (Manipal Heart Failure Registry) is envisioned to be four-fold: to enable a broad overview of the routine medical practices for HF treatment; to assess the healthcare resource utilization and drug utilization review for heart failure patients to assess the burden of disease (mortality, re-hospitalization) in the long term; and to provide a novel overview of the impact of HF syndrome on quality of life as well as health economics.

The investigators aimed to evaluate the effects of cardiomegaly associated with inspiratory muscle weakness on tricompartmental distribution of chest wall volumes, on the thickness of the right hemidiaphragm and on the contraction speed of the respiratory muscles. As method of the present research, a pilot cross-sectional study was conducted with fourteen (14) patients with heart failure, functional class II and III, clinically stable, with cardiomegaly. Two groups were formed: one group with inspiratory muscle weakness (WG) (maximal inspiratory pressure - MIP <70% predicted MIP) and a control group without weakness (CG). The pulmonary and respiratory muscle functions were assessed by spirometry and manometer, respectively. Before and after maximal exercise test, optoelectronic plethysmography was performed to evaluate the distribution of volumes, the kinematics and the contraction speed of chest wall muscles. The high-resolution ultrasonography was also used before and after the maximum test for obtaining diaphragmatic thickness

The purpose of the study is to recognize main causes of acute decompensation of chronic congestive heart failure.

We aim to test our method for measuring chemosensitivity (the ventilatory response to a change in carbon dioxide), which uses sinusoidal carbon dioxide stimuli. Hypotheses: Carbon dioxide sensitivity is dependent on the cycle time over which we administer the gas (frequency). Chemoreflex gain decreases as deadspace increases.

To assess whether a correlation exist between the degree of pulmonary clearance of free radical positive white bloodcells and platelets and the degree of pulmonary congestion in congestive heart failure (CHF) patients To asses whether cardiac resynchronization therapy improves pulmonary clearance of free radical positive white blood cells and platelets in CHF patients by alleviating pulmonary congestion Interaction of oxidative stress with circulating endothelial progenitor cells (EPCs) and presence of apoptotic endothelial (progenitor) cells

Chronic Heart Failure Analysis and Registry in the Tohoku District 2 (CHART-2 Study) is a large, prospective, hospital-based cohort study to investigate the following: Characteristics of patients with chronic heart failure and prognostic risks of these patients. Characteristics of patients with high risk for heart failure and critical factors which predict the development of symptomatic heart failure in these patients. The incidence and prognostic impact of metabolic syndrome in patients with chronic heart failure. The association between metabolic syndrome and the development of symptomatic heart failure.

We aim to investigate the prognosis of patients diagnosed with AF, particularly in relation to the development of subsequent stroke, heart failure, and myocardial infarction. We will explore the relationship between these outcomes and a range of risk factors.

Purpose of the observational study is to assess the capability of a satellite tele-echocardiography (STE) system to acquire and transmit echocardiographic images and clips to an echocardiographic core laboratory (ECL) in a real time mode without loss of quality. Additionally the prognostic efficacy of specific echo parameters in the cardiac resynchronization therapy response will be evaluated.
