NCT ID: NCT03214757 Not yet recruiting - Clinical trials for Pediatric Dilated Cardiomyopathy

A Study of Impact of Anemia on Morbidity and Mortality in Children With Dilated Cardiomyopathy

Start date: February 2018
Phase: N/A
Study type: Observational

Dilated cardiomyopathy is a heart muscle disorder characterized by systolic dysfunction and dilation of the left or both ventricles.Dilated cardiomyopathy can develop in people of any age or ethnicity, although it is more common in male than female persons occurring at a ratio of about three to one in male to female persons. Dilated cardiomyopathy is the predominant cause of cardiomyopathy in pediatric populations. Annual incidence in pediatric populations has been reported to be much lower than one to one hundred seventy thousand in the United States and one to one hundred forty thousand in Australia. Although pediatric dilated cardiomyopathy has a lower annual incidence than adult dilated cardiomyopathy, the outcome for pediatric dilated cardiomyopathy patients is particularly severe. Dilated cardiomyopathy is the most frequent cause of heart transplantation in pediatric patients. Data from international pediatric dilated cardiomyopathy registries indicate that the rates of death or heart transplantation over one and five year periods were thirty one percent and forty six percent, respectively. Onset of dilated cardiomyopathy is usually insidious but may be acute in as many at twenty five percent of patients. Approximately fifty percent of patients with dilated cardiomyopathy have a history of preceding viral illness.

A Pivotal Trial to Establish the Efficacy and Safety of Algisyl in Patients With Moderate to Severe Heart Failure

AUGMENT-HFII
Start date: August 2017
Phase: N/A
Study type: Interventional

AUGMENT-HF II is a study to evaluate the efficacy and safety of the Algisyl device. The purpose of this study is to investigate Algisyl employed as a method of left ventricular augmentation and restoration in patients with dilated cardiomyopathy. Algisyl will be injected into the myocardium under direct visualization during the surgical procedure. Structural abnormalities in the heart are known to play a central role in HF, and clinical evidence supports a strong causal relationship between cardiac chamber dilation and heart failure. Because dilation, and not contractile dysfunction, appears to be responsible for the severity of the disease, the mitigation or prevention of the deleterious structural abnormalities of the left ventricle appears to be an important therapeutic target for patients with this life threatening illness. Hence, a therapy that specifically reduces LV wall stress, targets LV dilatation and LV remodeling may offer an important new alternative in the treatment of heart failure. Algisyl is being investigated based on evidence that suggests an ability of the implants to reduce wall stress, reshape the LV chamber and reduce the LV chamber size as well as prevent the progressive ventricular dilation and remodeling associated with HF. The physiologic response to progressive exercise using direct measures of ventilation and gas exchange via the cardiopulmonary exercise test is an important diagnostic tool in the management of the patient with HF, quantifying responses to therapy, and as a reliable prognostic utility for predicting outcomes in patients with HF. Numerous studies have established the strong association of peak VO2 with mortality and morbidity risk in HF. Peak VO2 conceptually is considered an overall global marker of cardiopulmonary health and is a reflection of the degree of impairment in ventricular function ( the heart's pumping capacity), oxygen delivery and oxygen utilization. Hence, employing the change in peak VO2 as a primary endpoint in this clinical study provides a strong objective measure that can be interpreted in independent blinded fashion, to evaluate the result of the therapeutic intervention and provide an equally strong assessment of the prognostic implications for patients in the study. This clinical evaluation is intended to provide confirmatory evidence of the effectiveness and safety of the device Algisyl in patients with advanced heart failure.

Orodispersible Minitablets of Enalapril in Children With Heart Failure Due to Dilated Cardiomyopathy

LENA-WP08
Start date: January 2016
Phase: Phase 2/Phase 3
Study type: Interventional

Paediatric clinical trial in 50 children, from 1 month to less than 12 years of age, suffering from heart failure due to dilated cardiomyopathy, to obtain paediatric pharmacokinetic and pharmacodynamic data of enalapril and its active metabolite enalaprilat while treated for 8 weeks with enalapril in form of Orodispersible Minitablets (ODMTs), to describe the dose exposure in this patient population.

NCT ID: NCT02517814 Not yet recruiting - Clinical trials for Cardiomyopathy, Dilated

Vitamin D Supplementation Can Improve Heart Function in Idiopathic Cardiomyopathy

Start date: October 2015
Phase: N/A
Study type: Interventional

Vitamin D deficiency could be a high risk for cardiovascular diseases. It has been recently reported that vitamin D deficiency is another cause of heart failure and cardiomyopathies. It was found that vitamin D supplementation improved the heart function. The purpose of this study is to evaluate patients with idiopathic cardiomyopathies and determine whether vitamin D supplementation in cases where there is a deficiency, improves heart functioning.

NCT ID: NCT00646243 Not yet recruiting - Clinical trials for Ischemic Heart Disease

Echo Assessment of Intraventricular Dyssynchrony

IMPROVE
Start date: March 2008
Phase: N/A
Study type: Observational

Background. Clinical benefits of cardiac resynchronization therapy (CRT) have been clearly demonstrated in heart failure (HF) patients with severe left ventricular (LV) dysfunction and wide QRS at surface electrocardiogram. However, there is a growing evidence that QRS duration poorly predicts responses to CRT, and that ~30% of patients do not experience any benefit from CRT when pre-implant dyssynchrony is defined according to electrocardiographic criteria. A number of echocardiographic criteria have been proposed to assess mechanical LV dyssynchrony, but at present there is no consensus on their use to predict response to CRT. Study Design. The Italian Multicenter PROject on echo assessment of left VEntricular (IMPROVE) dyssynchrony study is a prospective, multicenter, observational study aimed to assess feasibility and predictive power of mechanical dyssynchrony assessed by echocardiography in consecutive consenting patients candidate to CRT by clinical and electrocardiographic criteria. IMPROVE will enroll 120 healthy subjects and 216 HF patients in 6 sites in Italy. CRT response criteria will be based on improvement in NYHA class and LV reverse remodeling evaluated by 3D-echocardiography. Enrollment is expected to conclude early 2009. Implications. CRT is today part of the therapeutic armamentarium for symptomatic HF patients refractory to medical therapy, with wide QRS complex and severe LV systolic dysfunction. The IMPROVE study has been designed to evaluate reference values of indexes of ultrasound mechanical dyssynchrony that have been proposed in the literature and compare their ability to predict response to CRT in HF patients.

NCT ID: NCT00518817 Not yet recruiting - Heart Failure Clinical Trials

The Cardiovascular Genetic and Therapeutic Implications of Muscular Dystrophy

Start date: August 2007
Phase: N/A
Study type: Observational

This study will have significant impact on muscular dystrophy patients as it promotes early screening for heart disease. With early identification, beneficial medical therapy can be started sooner, resulting in restoring and maintaining normal heart function. This is critical to the survival of these patients. We have reported previously that heart failure in all patients may have common mechanisms, the "final common pathway". Heart failure is a significant health problem with 5 million people in the US carrying the diagnosis and accounting for 12-15 million office visits and 6.5 million hospital days per year. The number of deaths from heart failure continues to increase. The data from this study could impact patients worldwide with heart failure by offering new insight into an ever-growing disease population and lead to significant changes in how they are currently treated.
