Filter by:The prevalence of hepatic cirrhosis in Romania is very high, with a 10-year mortality of 34-66%. Upward trend of mortality is observed. It is known that cirrhosis is associated with cardiac abnormalities. These can induce several complications of cirrhosis, and increase postoperative mortality. Therefore, it is a major public health issue and research in this field should be a priority. Few studies evaluated the cardiac function in cirrhotic patients, using only conventional echocardiography. However, this allows only the late diagnosis of cardiac dysfunction, which might be already irreversible. Consequently, description of new parameters, which could detect early dysfunction, becomes essential. There is no study designed to estimate intrinsic myocardial properties in cirrhosis. New methods (Tissue Doppler and Speckle-tracking echocardiography) could be essential to detect early cardiac dysfunction. The exact role of biological markers in the diagnosis of cardiac dysfunction remains to be clarified. Impaired cardiac function coupled with augmented vascular function could be the model for cirrhotic patients. This type of ventriculo-arterial interaction has never been described. The main objectives of our project are: 1. to investigate the mechanisms which lead to cardiac dysfunction; 2. to describe new parameters for the early diagnosis of cirrhotic cardiomyopathy; 3. to describe the type of ventriculo-arterial interaction; 4. the association between biological markers and echo parameters.
Cirrhotic cardiomyopathy is defined as a chronic cardiac dysfunction in patients with cirrhosis. It is suspected that this specific cardiac dysfunction contributes to the onset of complications in liver disease. The purpose of this prospective, randomized trial is to determine whether metoprolol succinate can revert cardiac dysfunction secondary to cirrhosis (cirrhotic cardiomyopathy), and prevent complications (renal dysfunction, mortality). A total of 100 patients with cirrhotic cardiomyopathy will be randomized (Group R) to receive metoprolol succinate or placebo; other 25 patients without cirrhotic cardiomyopathy (Group F) will only be followed up without medication. All patients will be evaluated in the beginning and again after six months. The assessment protocol includes clinical evaluation, electrocardiogram, echocardiogram, laboratory analysis and life quality questionaire. The end points will be cardiac remodeling, electrophysiologic changes, sympathetic activity, laboratory issue changes, renal function, quality of life, and mortality.
This study is designed to assess the efficacy, safety and tolerability of ixmyelocel-T compared to placebo (vehicle control) when administered via transendocardial catheter-based injections to patients with end stage heart failure due to IDCM, who have no reasonable revascularization options (either surgical or percutaneous interventional) likely to provide clinical benefit.
This study in healthy male and female volunteers will investigate the safety and tolerability of three increasing oral doses of tafamidis
The objective is to determine whether nebivolol, a beta-blockade drug, can prevent the development of heart disease in patients with Duchenne muscular dystrophy aged 10 to 15 year-old.
The purpose of this study is to determine if treatment with vitamin D3 of 10,000 International Units (IU) daily in vitamin D deficient patients for 6 months will improve B type natriuretic peptide (BNP), a marker of heart function, compared to placebo. The investigators also aim to determine if vitamin D helps cardiopulmonary function as evaluated by cardiopulmonary exercise test (CPX), laboratory values, strength, and quality of life in patients with stable congestive heart failure (Class II or III).
Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease, is a cause of disability including heart failure, atrial fibrillation, and sudden death, with an annual mortality varying from 1% to 6%. Obstructive sleep apnea (OSA) is extremely common among patients with established cardiovascular disease, including hypertension and atrial fibrillation and when present may contribute to worse cardiovascular outcome. Although patients with HCM do not necessarily have typical characteristics of patients with OSA, such as obesity and increasing age, there is recent evidence that OSA is extremely common among patients with HCM, with a prevalence ranging from 32% to 71%. The presence of OSA among patients with HCM is independently associated with worse structural and functional impairment of the heart, including atrial and aorta enlargement, worse New York Heart Association functional class, and worse quality of life. Therefore, the recognition and treatment of OSA is a new area of research that may impact in the management of patients with HCM.
Cardiac amyloidosis are related to the accumulation of fibrillar proteins in the extracellular leading to disruption of the cardiac tissue architecture. Amyloidosis in transthyretin (TTR) are the most common hereditary amyloidosis but remain poorly studied at heart. This is serious and deadly. The prevalence of TTR amyloidosis is probably underestimated in hypertrophic cardiomyopathy (HCM) often of unknown etiology because of the lack of systematic implementation of myocardial biopsy because of their side effects.
The purpose of this study is to determine in soccer fans whether and to which extend positive or negative emotions during the European soccer Championship affects Central Hemodynamics, Arterial Stiffness, Heartrate and Endothelial Dysfunktion.
This investigation is a prospective, randomized, single-blinded and multicenter design. The purpose of this study is to evaluate the benefit of atrial-synchronous biventricular (BiV) pacing in severely symptomatic hypertrophic obstructive cardiomyopathy (HOCM) patients with severe Left Ventricular Outflow Tract (LVOT) obstruction implanted with a Cardiac Resynchronization Therapy - Pacing (CRT-P) device. Randomization - Implant will be performed (CRT-P). - Patients will be randomized 1:1 to either Treatment Group (Optimized Biventricular (DDD) pacing) or Control Group (Back-up Atrial (AAI) pacing) during the first 12 months: - Treatment Group. The patient´s device is programmed to optimized DDD BiV pacing - Control Group. The patient´s device is programmed to back-up pacing AAI. - After 12 months, the patients initially randomized to the Treatment Group (Optimized DDD Pacing) will continue in the same group. The patients initially randomized to Control Group (AAI Back-up Pacing) will be changed to the Treatment Group (Optimized DDD Pacing). And all the patients will be followed 12 months more.
