Filter by:This study was conducted on 24 patients who have ischemic dilated cardiomyopathy, underwent non cardiac surgery in the lower half of the body under the effect of combined spinal epidural anesthesia at Assiut university hospital. Intraoperative Hemodynamic monitoring including invasive blood pressure, heart rate, and CVP was established, in addition to pre and postoperative, 12 lead ECG, echocardiography, and venous sampling for Brain natriuretic peptide measurement were done . This study tried to assess the safety of this anesthetic technique on such group of cardiac patients along over the hospital stay period and up to 6 months postoperatively, in addition to the predictability of Brain natriuretic peptide as a cardiac biomarker regarding to the major adverse cardiac events and cardiac mortality for these group of patients .
Arrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: 1. Discover new genes or altered genes (variants) which cause AVC 2. Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) 3. Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. 4. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies
The purpose of this study is to develop imaging protocols when using cardiovascular magnetic resonance (CMR) to assess cardiac functions, morphology and tissue characterization. The National Heart Research Institute Singapore (NHRIS) houses two dedicated CMR scanners to support the numerous investigator initiated projects in patients with various cardiac pathologists. By optimizing novel CMR sequences used in these studies, scanning time can be shortened for patients with underlying cardiac diseases.
The aims of the DCM Precision Medicine Study are to test the hypothesis that DCM has substantial genetic basis and to evaluate the effectiveness of a family communication intervention in improving the uptake and impact of family member clinical screening.
The aim of this randomized controlled study is to investigate the effect of continues positive airway pressure (CPAP) treatment in patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnea (OSA). The primary endpoint is left ventricular function measured by magnetic resonance (improvement of at least 4%) after six months treatment with CPAP. The secondary endpoints include diastolic dysfunction, cardiovascular biomarkers and quality of life.
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.
The My Research Legacy Pilot Study will establish a participant registry that collects self-reported health data and answers to online survey questions about individual daily choices, diets, and exercise; data from wearable devices; and, (optional) data from genome sequencing analysis. Individuals under the age of 50 who meet eligibility criteria will answer questions using the American Heart Association's (AHA) Life's Simple 7™ My Life Check v4.0 three times over the course of 6 months and transmit data from a Fitbit Charge 2 device. All other individuals who are interested in the study and meet entry criteria may also enroll.
Dilated cardiomyopathy (DCM) causes significant morbidity and mortality and is the third most common cause of heart failure and the most frequent reason for heart transplantation. The etiology of dilated cardiomyopathy(DCM) is complex. There is a growing body of literature suggesting that the humoral immune system activation and autoantibodies against myocardial generation play an important role in the progression of DCM. At present immunoadsorption technology has been successfully applied in autoimmune antibody removal treatment of a variety of diseases. And some applications of immunoadsorption(IA) in patients with DCM showed that immunoadsorption(IA) can indeed reduce the autoantibodies, improve symptoms and prognosis, but additional research is needed to identify indications and instruments for the IA treatment of DCM.
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.
