Filter by:Background: Honey, as a natural product produced by honey bees, has anti-oxidant, anti-microbial, anti-inflammatory and immunomodulator properties. A few reports suggest that honey might have positive effects on cardiovascular diseases. Methods: This was a randomized controlled study, which was carried out on 50 children, aged 2 to 12 years, suffering from idiopathic dilated cardiomyopathy (IDC). Patients were randomly assigned into two equal groups: the honey group and the control group. In the honey group, honey was provided in a dose of 1.2g/kg/day for three months in addition to the traditional treatment of IDC. The patients in the control group received only their standard treatment, without honey. The main outcome measure was the percent change in the ejection fraction (EF) and the fraction shortening (FS) shown in echocardiography.
Heart failure with reduced left ventricular ejection fraction (HFrEF) is the most common form of chronic heart failure in subjects ≤ 75 years of age. Beta-blocker therapy greatly reduces mortality and improves ventricular function in HFrEF patients, but 30-40% of patients do not show improvement in ventricular function with beta blockade. An extensive gene signaling network downstream from the beta1-adrenergic receptor, the primary target of beta-blocker therapy is likely important for development and progression HFrEF. Pathologic changes in this gene signaling network are only reversed towards normal levels when ventricular function improves. One potential mechanism for failure to improve ventricular function in HFrEF patients unresponsive to beta blocker therapy is a lack of heart rate reduction. Ivabradine is an FDA-approved medication believed to have therapeutic benefit in HFrEF patients through reduction in heart rate independent of beta-blockade. Ivabradine has been shown to reduce the risk of hospitalization for worsening HF in patients with stable, symptomatic chronic heart failure with reduced EF (≤ 35%)in sinus rhythm with resting heart rate ≥ 70 bpm and who are on maximally tolerated doses of beta blockers or who have a contraindication to beta blockers. Given the high rate of mortality and hospitalization of HFrEF patients even with current therapies, there is a large unmet need for improving HFrEF therapy. The goals of this study are to test the hypothesis that heart rate reduction is an important antecedent for improvement in ventricular function, and to identify components of the beta1-adrenergic receptor gene signaling network responsible for improvement in ventricular function caused by heart rate reduction.
Pediatric dilated cardiomyopathy (PDCM) is the most common form fond in children. Water-soluble coenzyme Q10 (ubiquinol) is better absorbed than lipid-soluble coenzyme Q10 (ubiquinone) and is directly involved in the antioxidant cycle. Because coenzyme Q10 has shown significant health benefits in adult patients with cardiovascular disease, it is worth studying water-soluble coenzyme Q10 supplements to evaluate their potential role as complementary therapy for PDCM. The purpose of this study is to explore the potential role of water-soluble ubiquinol in complementary therapy for pediatric cardiomyopathy. We will recruit 25 children with primary PDCM (age 0-20 y) and examine the relationship between coenzyme Q10 level and cardiac function (left ventricular fractional shortening and ejection fraction, and B-type natriuretic peptide), oxidative stress (malondialdehyde), antioxidant enzymes activity (catalase, glutathione peroxide, and superoxide dismutase), and inflammation (high sensitivity C-reactive protein and interleukin-6) in PMC after 6 months water-soluble ubiquinol supplementation (10 mg/kg BW/d, by oral drops). In addition, we will assess the quality of life of PDCM patients by questionnaire. Through this study, we expect to demonstrate that water-soluble coenzyme Q10 will be a complementary therapy for PDCM, and will improve cardiac function, increase antioxidant capacity, slow deterioration of cardiac function and reduce inflammation, and further reduce the rate of heart transplantation and increase quality of life in PDCM.
Acute myocarditis is a serious illness affecting a young population with a very variable course (of full recovery at the onset of dilated cardiomyopathy (DCM), or even sudden death). Very few studies have examined the predictors of death and serious cardiovascular events in acute myocarditis and have carried on numbers of restricted patients. What little data results in a lack of a precise recommendation on the management and the follow-up period of patients. This observational study should identify serious prognostic factor for cardiovascular events in order to provide a support strategy and more appropriate monitoring of myocarditis.
First, investigators must determine the physiological standards across age classes of myocardial stiffness estimated by Elastography in ultrafast (estimated right ventricular stiffness [VD] and left ventricular [LV]). This will be done in groups of children without heart condition, age group (10 children per group, four age groups [0-1mois, 1 month-1 year 1 year-5 years, 5 years-15years]). Secondly, investigators will evaluate myocardial stiffness Elastography (RV and LV) on different groups of children (same age group) with cardiomyopathy and examine correlations with the conventional parameters of systolic and diastolic function of both ventricles and with myocardial strain values. The total population of the study will be 120 children (40 healthy, 80 patients).
The bone marrow mononuclear cell fraction has been used as therapy after myocardial infarction and in dilated cardiomyopathy in adults. The absence of adult co-morbidities may enhance the potential effectiveness of pediatric stem cells.This study is a randomized, crossover, placebo controlled pilot study to primarily determine the safety and feasibility of stem cell intracoronary therapy in children. Secondary end points are MRI measurements and NTproBNP. Ten children (mean age 7.2 years, range 2.2-14.1, 6 male) with dilated cardiomyopathy (NYHA/ Ross Classification 2-4) will be recruited. Bone marrow aspiration MRI and cell injection are performed under the same anaesthetic. Patients will be crossed over at 6 months.
Acute consumption of dietary nitrate (as beetroot juice) has been shown to improve exercise capacity in athletes, healthy adults and subjects with both peripheral vascular disease or COPD. Many patients with dilated cardiomyopathy have reduced exercise capacity, The investigators hypothesized that acute nitrate consumption might increase incremental shuttle walk test (ISWT) distance in dilated cardiomyopathy subjects compared to a placebo beetroot juice.
: Fibrosis, in general, is a scarring process, which is characterized by fibroblast accumulation and excess deposition of extracellular matrix (ECM) proteins, which leads to distorted organ architecture and function. The contribution of fibrogenesis to impaired cardiac function is increasingly recognized. The fibrotic ECM causes increased stiffness and induces pathological signaling within cardiomyocytes resulting in progressive cardiac failure. Also, the excessive ECM impairs mechano-electric coupling of cardiomyocytes and increases the risk of arrhythmias. But today patient treatment and prognosis is based on ejection fraction quantification, QRS duration, and symptoms. Hypothesis: the increased level of fibrosis quantified using T1 mapping technique, compared with normal value, is of prognostic value in patient with dilated cardiomyopathies under optimal treatment. Methods: 330 patients are planned to be included and followed for 2 years
This is a rollover study designed to investigate the safety and effectiveness of investigational study drug ARRY-371797 in patients who previously received ARRY-371797 in a study for patients with LMNA-related dilated cardiomyopathy sponsored by Array BioPharma and may, in the Investigator's opinion, derive benefit from continued treatment.
Purpose :Research into the impact of Qiliqiangxin capsule on IFN-γ，IL-4，NT-proBNP in dilated cardiomyopathy patients with heart failure. Methods :Data were collected from the patients with idiopathic dilated cardiomyopathy ( cardiac function NYHA Ⅱ-Ⅳ) in the first affiliated hospital of Harbin Medical University from May 2012 to April 2014. These 30 cases were treated under the recommendations of normal diagnosis and treatment in cardiomyopathy. This experiment was randomized double-blinded，the experimental interferences were avoided and patients were divided into the experimental group and the placebo group. The patients in experimental group received the relevant tests and inspections before the beginning of experiment，signed the informed consent. Then the investigators get the venous blood centrifugalization and cryopreservation. The patients take the medicine qiliqiangxin three times per day，four tablets at a time. Afrer a month，the investigators evaluated the symptoms，the function of heart，blood pressure，heart rate and keep blood specimens. Three and six month later，electrocardiogram and echocardiography were taken and the determination of the NT - proBNP was done. The placebo group was followed up in the same way.
