Active clinical trials for "Heart Failure"

Vasco trial is a no profit, multicenter, international, prospective, randomized study designed to evaluate the clinical benefits of a remote monitoring management based on ILR vs standard practice in patients with high risk of cardiac arrhythmias, heart failure and left ventricle ejection fraction (LVEF)> 40% .The study will enroll about 331 patients (221 in the ILR group and 110 in the in-hospital follow-up group).

Cardiac Resynchronization Therapy (CRT) is an established treatment for patients with systolic heart failure and bundle branch block, improving functional capacity, quality of life and reducing morbi-mortality. However, one-third of patients are non-responders. Among factors associated with non-response, suboptimal electrical settings of the device, i.e. inadequate pacing vector selection and atrioventricular (AV) delay, is an important cause. The aim of the study is to investigate whether the optimization of CRT settings (pacing vector and AV delay) results in improved clinical and echocardiographic outcomes in a non-responder CRT population after 6 months of therapy.

Endothelial dysfunction and microvascular disease have been shown to play an important role in both the development and progression of heart failure. Retinal imaging provides a unique opportunity to non-invasively assess retinal microcirculation. Leveraging the non-invasiveness and relative ease of use of retinal imaging, we propose to investigate its clinical utility in assessing endothelial/microvascular dysfunction across the spectrum of heart failure. We aim to test the hypothesis that the degree of abnormality in retinal vessels is associated with heart failure disease severity, endothelial/microvascular dysfunction, and, potentially, treatment responses.

The goal of the present study is to determine the occurrence of wild-type and hereditary transthyretin amyloidosis cardiomyopathy among patients with the diagnosis of idiopathic peripheral neuropathy in the setting of a state-of-the-art diagnostic work-up; the investigators believe that the identification of patients with ATTR-CM in this setting can contribute to the early diagnosis of a largely underrecognized condition and, therefore, offer conditions to timely initiation of appropriate therapy with impact on prognosis of patients.

The ICONIC-M study is a multicenter randomized controlled study to assess patient response to CRT comparing ECGI map guided left ventricular lead placement with empirical lead placement. The hypothesis of the investigation is to demonstrate that CRT LV lead implantation guided by a map obtained with the Amycard 01C System and showing LV Latest Electrical Activated Site (LEAS) in combination with a CT cardiac venogram improves CRT outcome. An improved CRT outcome is defined as a ≥30% increase in LVESVi reduction compared to empiric CRT LV lead implantation. The sample size will be 136 in the Control arm and 194 in the Active arm. A total of 330 subjects. The study follows an adaptive design, in where one interim analysis at 70% enrollment will be performed. The sponsor may stop enrollment when either one of the following conditions apply: Statistical significant difference between groups in the primary endpoint has been reached confirming a difference in reduction of the LVESVi of ≥30% in the Active arm compared to the Control arm There is no trend or reason to believe statistical significance will be reached with a higher sample size. Statistical significance (primary endpoint) is reached at interim (70%) or at total (100%) of enrollment with a significance value P lower than 0.025.

In the type 2 diabetic population, some patients are particularly at risk of developing early heart failure. Finding markers to identify these at-risk individuals is therefore an important scientific objective in order to avoid/delay the development of heart failure. The protocol will be proposed to type 2 diabetic patients hospitalized for insulin therapy upon admission to the diabetology department and healthy volunteers.

This is a multicenter, prospective, single-arm Continued Access study of the Optimizer Smart System with CCM therapy.

Purpose and Objective: Heart failure therapies including beta-blockers, ACE-inhibitors, aldosterone antagonists, implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT) devices have proven beneficial but are underused in eligible patients. The investigators seek to determine if automating referral to cardiologists and electrophysiologists through an intelligent electronic medical record system can improve adherence to American College of Cardiology (ACC)/ American Heart Association (AHA) heart failure guideline recommended therapies. Study activities and population group: The AMERICA-HF trial will be a randomized, single-center, single blinded study comparing standard-practice provider initiated cardiovascular specialty referral to experimental automated medical record driven cardiovascular specialty referral. An investigational program will automatically screen all finalized electronic reports from clinically indicated transthoracic echocardiogram studies performed in the Duke University Echo Lab system and create an automated query to obtain HF ICD-9 codes. Eligible patients will be randomly assigned to participate in a registry (n=125) or automated electronic medical record (EMR) based subspecialty care intervention arm (n=125). Data analysis: The primary endpoint is rate of adherence (%) to ACC/AHA HF guideline recommended therapies at 3, 6, and 12 month follow-up among patients randomized to the registry compared to the intervention. Differences in characteristics (including use of guideline recommended therapies) will be tested using Pearson Chi-square tests for categorical variables and Wilcoxon two-sample tests for continuous variables. Time to event analysis will be performed for the secondary endpoints of hospitalization or death.

The purpose of this research is to determine if there is a greater behaviour change in self management of heart failure following reinforced multimedia education focusing on physical activity as compared to standard care. It is the investigators belief that participants who receive DVD education in addition to usual care will show improved self management in comparison to receiving usual care alone. The investigators anticipate fewer hospital admissions due to improved self care management.

Hypothesis: Treatment with levosimendan will preserve myocardial function and hemodynamics after cardiac surgery and lead to reduced stay at intensive care unit
