NCT ID: NCT03531151 Recruiting - Heart Failure Clinical Trials

MRI of Myocardial Infarction

MRIMI
Start date: April 1, 2018
Phase:
Study type: Observational [Patient Registry]

Heart failure (HF) is an enormous health burden affecting approximately 5.1 million people in the US and is the cause of 250,000 deaths each year. Approximately 50% of HF is caused by myocardial ischemia and requires immediate restoration of coronary blood flow to the affected myocardium. However, the success of reperfusion is partly limited by intramyocardial hemorrhage, which is the deposition of intravascular material into the myocardium. Hemorrhagic reperfusion injury has high prevalence and patients have a much greater risk of adverse left ventricular remodeling, risk of fatal arrhythmia, impaired systolic function and are hospitalized at a greater rate. Recent magnetic resonance imaging techniques have improved assessment of reperfusion injury, however, the association between MRI contrasts and reperfusion injury is highly unclear, and lacks specificity to IMH. Improved imaging of IMH and accurate knowledge about its spatial and temporal evolution may be essential for delivery of optimal medical therapy in patients and critical to identify patients most at risk for adverse ventricular remodeling. The overall goal is to investigate the magnetic properties of hemorrhage and develop MRI techniques with improved specificity to hemorrhage. New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. The investigators will perform a longitudinal observational study in patients after reperfusion injury to validate these methods, compare the methods with conventional MR contrasts and develop MR methods for imaging humans.

NCT ID: NCT03526601 Recruiting - Heart Failure Clinical Trials

Screening Of Adult urBan pOpulation To diAgnose Heart Failure

SOBOTA-HF
Start date: May 10, 2017
Phase:
Study type: Observational [Patient Registry]

Screening Of adult urBan pOpulation To diAgnose Heart Failure (SOBOTA-HF) is a cross-sectional prevalence study in a representative sample of Murska Sobota residents aged 55 years or more. Individuals will be invited to participate in a screening with NT-proBNP. All subjects with NT-proBNP ≥ 125 pg/mL will be invited for a diagnostic visit that will include history and physical examination, electrocardiogram, echocardiography, ankle brachial index, pulmonary function tests, body composition measurement, physical performance tests and questionnaires. To validate the screening procedure, a control group (NT-proBNP < 125 pg/mL) will undergo same diagnostic evaluation. An external center will validate echodardiography exams and the HF diagnosis will be adjudicated within an independent HF expert panel. Overall and age specific HF prevalence will be calculated in individuals ≥ 55 years and extrapolated to the whole population.

NCT ID: NCT03524001 Recruiting - Clinical trials for Heart Failure With Reduced Ejection Fraction

Bifocal Right Ventricular PAcing in Right Bundle Branch blocK and Heart Failure With Reduced Ejection Fraction. The Study Tests the Superiority of Right Ventricular Bifocal Stimulation Over VVI Implantable Defibrillator in Right Bundle Branch Block and Heart Failure.

BiPARK-HF
Start date: February 1, 2018
Phase: N/A
Study type: Interventional

RATIONALE: Cardiac resynchronization therapy (CRT) is known to improve cardiac performance and to reduce morbidity and mortality in reduced-ejection fraction heart failure (HFrEF) despite optimal medical therapy (OMT). Several studies have shown that patients with with left bundle branch block (LBBB) respond favourably to CRT, whereas there is less certainty about non-LBBB morphology. Specifically, whether patients with right bundle branch block (RBBB) and HFrEF benefit from CRT is unclear. Some studies suggest lack of favourable outcomes. It follows from this that VVI implantable defibrillator are implanted in most RBBB patients.On the other hand right ventricular bifocal stimulation could be useful as an alternative approach in patient with RBBB. It consists of two endocardial leads implanted in right ventricle. The first lead is implanted in His bundle area, and the second lead is in the right ventricle apex. In this way bifocal pacing could decrease the inter- and intraventricular delays, thus improving left ventricular hemodynamics. However no specifically randomized studies are designed to date. PURPOSE: To demonstrate the superiority of right ventricular bifocal stimulation over placebo (VVI implantable defibrillator) in RBBB and HFrEF despite OMT. DESIGN Multicenter prospective randomized, double blind cross-over study. MASKING Investigator responsible for device programming is masked from having knowledge about clinical, functional, and echocardiographic data. On the other hand echocardiographist is masked from having knowledge about stimulation mode. Patients are masked from having knowledge about their clinical, functional, and device data. POPULATION At least fifty patients would be enrolled. The enrollment period should be one year. Study overall duration should be two years. ELIGIBILITY CRITERIA RBBB and HFrEF (left ventricular ejection fraction ≤35%) in sinus rhythm, in NYHA class II-III or ambulatory IV despite OMT. EXCLUSION CRITERIA -Refusal or withdrawal of informed consent.Renal failure (glomerular filtration rate ≤ 60 ml/min).Life expectancy < 12 months.Active neoplasm.Permanent atrial fibrillation.40 days following acute coronary syndrome.Atrio-ventricular block (from second degree AV block).Valvular heart disease with surgery indications. PROTOCOL Each patient undergoes baseline assessment. Pharmacological therapy, hospitalization,NYHA functional class, QRS complex informations, type of heart disease and comorbidities are collected. Quality of life (QOL) is defined by Minnesota Living with Heart Failure questionnaire. Functional capacity is assessed by 6MWT (optionally by cardiopulmonary exercise test). Trans-thoracic echocardiogram is performed, analyzing: left-ventricle diameters and volumes, left-ventricle ejection fraction (LVEF), left atrial diameter and area, TAPSE,valvulopathy,systolic pulmonary artery pressure. All patients undergo bifocal right ventricular resynchronization therapy: right atrial lead is implanted, whereas the first ventricular lead is placed in His bundle area, and the second ventricular lead in the right ventricle apex. Then the leads are connected to the respective channels of a CRT-D generator.After the implant, all devices are programmed in VVI mode. After the first 40±10 days (first f-up) patients are 1:1 randomized to VVI mode 40 beats/minute (placebo arm) or bifocal DDD-mode 60 beats/minute (with VV delay 0 msec and optimal AV delay). After six months (second f-up) a clinical and instrumental assessment equal to baseline is performed, as well as devices electrical parameters control. Then arms cross-over is performed (from VVI-mode to bifocal DDD-mode and vice versa). At 12 months (end of follow-up) an evaluation equal to that performed at 6 months is assessed. Echocardiographic data are unravelled to the investigator responsible for device programming. In this way the stimulation mode able to determine the best clinical improved (VVI or bifocal DDD mode) is programmed and the study closes. PRIMARY ENDPOINT The main assumption is that bifocal stimulation can increase of at least 20% the distance walked during 6MWT in respect of baseline and VVI-mode.The primary endpoint is the distance walked (expressed by meters) during 6MWT, as assessed at baseline, 6-months follow-up and 12 months follow up. Specifically changes in 6MWT observed during bifocal DDD-mode compared to baseline and to VVI mode would be significative if there is an increase of at least 20%. SECONDARY ENDPOINT Secondary endpoint is bifocal stimulation therapy response, defined by at least one of the following criteria, evaluated at baseline, 6-months follow-up and 12 months-follow-up in comparison to baseline and VVI mode: NYHA functional class improvement; changes in 6MWT, defined by an increase in distance walked major or equal to 30%; LVEF improvement major or equal to 25%;Left ventricular telesystolic volume reduction major or equal to 15%

NCT ID: NCT03517514 Recruiting - Acute Heart Failure Clinical Trials

Heart Failure Hospital Readmissions and Physical Therapy

Start date: February 1, 2018
Phase:
Study type: Observational

This is a dissertation study which is divided into three different studies in order to answer the main research question (Study 3). The primary aim of this research (dissertation) is to investigate all-cause 30-day hospital readmission using functional mobility (5mWT, 30STS, 6MWT, TUG), psychosocial attributes (KCCQ-12, HADS, ESSI), adherence to home exercise program, participation in a supervised exercise program, and number of follow up checkups with physicians or advanced health providers of patients with Acute Decompensated Heart Failure (ADHF) diagnosis who were discharged from a tertiary teaching hospital. Study 1: What is the effect of acute physical therapy on functional ability in individuals admitted with ADHF? Study 2: What is the effect of acute physical therapy on psychosocial attributes in individuals admitted with ADHF? Study 3: Which factors such as functional mobility (5mWT, 30STS, 6MWT, TUG), psychosocial attributes (KCCQ-12, HADS, ESSI), adherence to home exercise program, participation in a supervised exercise program, and number of follow up checkups with physicians or advanced health providers predict all-cause 30-day hospital readmission in patients discharged from a tertiary, teaching hospital with ADHF diagnosis?

NCT ID: NCT03514108 Recruiting - Diabetes Clinical Trials

DANHEART (H-HeFT and Met-HeFT)

DANHEART
Start date: March 1, 2018
Phase: Phase 4
Study type: Interventional

The present study is testing in a combined design to types of drugs in patients with chronic heart failure: 1) Hydralazine in combination with isosorbide dinitrate (BiDil) and 2) Metformin hydrochloride. The study is double blind, placebo controlled. 1. The first hypothesis is that hydralazine in combination with isosorbide dinitrate can reduce mortality and hospitalization with worsening heart failure. 2. The second hypothesis is that treatment of underlying insulin resistance/ type 2 diabetes with metformin in heart failure patients with moderately to severely reduced LVEF can reduce mortality and cardiovascular hospitalizations. Among secondary endpoints are reduction in new-onset diabetes in heart failure patients with insulin resistance and diabetes risk profile and patient safety.
