Active clinical trials for "Heart Failure"

The readmission of Heart Failure (HF) patients for exacerbation HF within 30-day is unmet goal. The mail reason for readmission is excessive accumulation of fluid in patient's lung. According our data (1,2) around 40% of HF patient have excessive lung fluid at discharge from HF hospitalization ("unacceptable" residual congestion on discharge). In other words, around 40% patients are discharged from HF hospitalization prematurely when they are not ready to be discharged. Only 60% of HF patients are discharged from HF admission with "acceptable" level of residual pulmonary congestion (2). There are some techniques to assess "readiness" of HF patients for discharge. Pulmonary congestion (lung fluid accumulation) may be assessed non-invasively by measurement Brain Natriuretic Peptide (BNP), (3,4), by lung ultrasound (LUS), (5-7) and by Lung Impedance (LI) method (1,2). LUS is operator depended technique. LI and BNP techniques are most reliable methods (2) and easy to use.

An Observational Study to assess the Prevalence of Heart Failure in Type 2 Diabetes Patients in India.

Diastolic dysfunction refers to abnormal mechanical properties of the myocardium and includes abnormal LV diastolic distensibility, impaired filling and slow or delayed relaxation- regardless of whether the ejection fraction is normal or depressed and whether the patient is asymptomatic or symptomatic. Epidemiologic studies have demonstrated high prevalence of diastolic heart failure (DHF). The quality of life of these patients is impaired and the clinical outcomes are similar to those with heart failure with systolic dysfunction. Therefore diastolic dysfunction has significant adverse economic impact that is expected to grow further with time. Clinical characteristics alone may not be sufficient to diagnose diastolic dysfunction. A number of invasive and non-invasive parameters have been proposed to diagnose diastolic dysfunction. Most of the presently used non-invasive parameters have a number of limitations. High fidelity measurement of the left ventricular pressures is needed to accurately diagnose diastolic dysfunction. Obtaining it in routine clinical practice is impractical. In this protocol the investigators have proposed a novel non-invasive parameter called 'Torsional Hysteresis' as a measure of diastolic function. This will be measured using non-invasive cardiac MRI technique. During left ventricular contraction and relaxation, myocardium deforms. During cardiac cycle the myocardium goes back to baseline state prior to beginning of each contraction. However the rate with which it returns to the baseline state is variable. Torsion indicates relative wringing motion of the ventricle around a left ventricular axis and is a global parameter of left ventricular deformation. The parameters have defined a new parameter called torsional hysteresis based on non invasive cardiac MRI assessment. The parameters have hypothesized that for diastolic dysfunction, the torsional hysteresis area is increased as compared to no diastolic dysfunction group.

The purpose of this multicenter post-approval study is to evaluate the acute and chronic performance of the QuickFlex® μ 1258T left ventricular (LV) lead.

It is the aim of this register to document the development of therapies by implantation of Cardioverter/Defibrillators (ICDs) and/or Cardiac Resynchronization therapy (CRT)-Systems.

The purpose of this clinical investigation is to assess the programming behavior of the physicians in the patient cohort. Furthermore, the acceptance level of specific programming recommendations based on the patient's clinical needs and primary indications will be evaluated by comparing parameters determined by the feature IBP to daily life programming chosen by physicians.

The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.

During the last decade, progress has been made in the management of heart failure. However, the changing characteristics of patients and practices in the "real world" and their impact on the prognosis of patients admitted for acute heart failure remain poorly studied. 2000 consecutive patients recruited in a single day in hospitals volunteered to participate in the cohort during a day dedicated.

Biomarkers representing distinct biological domains including neurohormonal, inflammatory, metabolic-nutritional, oxidative-nitrosative and myocardial injury, might alone or in combination provide prognostic information on mortality in heart failure patients with preserved or impaired systolic function.

The purpose of this study is to collect and analyze electrical measurements, timing, and signals from a CRT-D device in heart failure patients who either already have an implanted left atrial pressure sensor or will undergo a simultaneous implantation of a left atrial pressure sensor and a CRT-D device. These devices may be placed at the same time or separately (staged procedure) at the discretion of the investigator. A comparison will be made between the information gathered from the CRT-D system and the information gathered by the left atrial pressure sensor.
