Active clinical trials for "Heart Failure"

To characterize the physiological signals collected from a Wearable Cardiac Monitor (WCM) prototype device in subjects with heart failure and preserved ejection fraction (HFpEF) and compare against signals from subjects with heart failure and reduced ejection fraction (HFrEF). To evaluate the relationship of physiological signals measured from a wearable cardiac monitor (WCM) prototype device with ECHO measures of systolic and diastolic function

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 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 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.

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

A retrospective cohort study performed in the GPRD,UK. All patients with incident prostate cancer identified between 1 Jan 1999 and 31 Dec 2005 and a frequency-matched cohort of the general population will be followed- up for two outcomes; CHD including acute myocardial infarction or death from coronary heart disease and HF until Dec 31, 2006. Outcomes will be validated through requests to primary care physicians. Incidence rate´ratios of CHD and HF in the two cohorts will be calculated. In the cohort of prostate cancer the relative risk of CHD and HF associated with the use of bicalutamide compared to non-use will be estimated.
