Filter by:Cardiomyopathy in children is a serious disease which can result in death, disability, heart transplantation or serious heart rhythm disorders. Doctors know little about the causes of cardiomyopathy but would like to learn more. In fact, up to 50-75% of cases in children have no known cause. For this reason, the purpose of this study is to identify genes that cause cardiomyopathy or that influence how people with cardiomyopathy do over time. These findings could improve disease prevention, surveillance, early management, and prognosis.
The purpose of this study is to demonstrate correlation of the H/M ratio of AdreView when derived from a large field of view Anger SPECT system and from a small field of view high sensitivity (CZT) SPECT system.
The objective of this trial is to study the effects of omega-3 PUFA supplementation on the inflammatory response and lipid profile in patients with chronic Chagas cardiomyopathy. Study Type: Interventional Study Design: A total 40 patients will be randomly assigned into two parallel groups. The intervention will be treatment with omega-3 PUFAs at a dose of 3 g/day for 8 weeks, compared to placebo (corn oil). The primary endpoints will be the concentrations of inflammatory markers (IL-1, IL-2, IL-4, IL-6, IL-10, TNF-alpha, IFN-γ, and TGF-β). Secondary endpoints will be the fasting glucose, lipid, and anthropometric profiles.
effect of B blocker was first evaluated in patient with cardiomyopathy not induced by ischemia and idiopathic which as the most common causes of cardiomyopathy. Effect of BB on Thalassemia cardiomyopathy was evaluated in this study
Phospholamban (PLN) R14del mutation carriers may develop dilated cardiomyopathy (DCM) and/or arrhythmmogenic cardiomyopathy (ACM). Analogous to other inherited cardiomyopathies, the natural course of the disease is age-related ("age-related penetrance"); after a presymptomatic phase of variable length many PLN R14del-carriers progress to overt disease, and are diagnosed with either DCM or ARVC. PLN is a regulator of the sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) pump in cardiac muscle and thereby important for maintaining Ca2+ homeostasis. Cardiac fibrosis appears to be an early manifestation of disease. The investigators hypothesize that treatment of presymptomatic PLN R14del-carriers with eplerenone, which by virtue of its mineralocorticoid(aldosterone)-blocking properties is a strong antifibrotic agent, reduces disease progression and postpones onset of overt disease.
There is a certain gene called sarcoplasmic reticulum gene (SERCA2a), which is found in heart muscle. This gene is also found in blood vessels and skin tissue. When active this gene builds a crucial protein inside the heart muscle called SERCA2a protein. This is responsible for regulating calcium levels inside your heart muscle. When this gene is not activated, studies have shown that it can lead to abnormal electrical currents in the heart that can lead to death. The investigators are conducting this study to prove that SERCA2a gene is inactive in patients with kidney disease. Scientists found that patient at risk for abnormal electrical currents in the heart can be tested by what they called "microvolt Twave alternans." This is a very delicate machine much more sensitive than a regular electrocardiogram that you do at the cardiology office.
The objective of the study is to determine whether the combination of the bile acid TUDCA, and doxycycline will slow the progression of familial and senile amyloidosis.
The investigators have created a way of quickly collecting information in a large scale young population regarding the presence of some severity indicators that may allow us to classify them into: seemingly "low risk" and possible "elevated risk" for the presence of heart disease. It would have to be a short questionnaire, in order to receive a great adherence but that could simultaneously provide precise information, with an adequate description of symptoms and warning signs, in a way that a triage in the young adult population could be performed in the general young adult population in order to select individuals with an indication for personalized clinical evaluation and possible need of complementary diagnostic means. Based on this premise the investigators have developed a fast-response questionnaire named the Sudden Cardiac Death Screening Of risk factorS (SCD-SOS). This questionnaire has already been tested in a population of approximately 1500 young adults, and some changes have been introduced in order to refine its performance. To best of the investigators knowledge, there are no large scale European surveys estimating the prevalence of cardiac disease and associated clinical symptoms in a non-selected (non-athlete) population of this age group. Purpose: To screen a young adult population from central regional of Portugal for heart disease possibly associated to a high risk of Sudden Cardiac Death (SCD). To determine the national prevalence of clinical symptoms of heart disease and of heart disease with increased risk for SCD in this age group. To detect young adults in risk of SCD and with an indication for evaluation by a cardiologist, and possible need of: - medical treatment - electrophysiologic (EP) study and percutaneous ablation - an implantable cardiovertor defibrillator - a pacemaker - other type of specialized cardiac intervention
Presently, the left ventricular lead is placed in a similar position for all patients. It is not known whether placing this lead in different positions in the heart will make the heart pump better. In this study, the investigator will collect measurements of the heart's electrical activity during an Electrophysiology Study (EP study or EPS). The hope is that these measurements will provide the know how to develop an individualized left ventricular lead placement "prescription" for patients referred for left ventricular lead pacing.
The purpose of this study is further risk stratification of patients receiving implantable cardioverter-defibrillator in primary prevention of sudden cardiac death.
