Filter by:Taurine as an adjunct for early left ventricular recovery in peripartum cardiomyopathy
Objective of the study: to evaluate whether alfieri technique improves clinical and hemodynamic results compared to transaortic mitral valve secondary cord cutting in patients scheduled to septal myectomy for severely symptomatic hypertrophic obstructive cardiomyopathy.
Diabetic cardiomyopathy( DCM) is a major complication of diabetes and is a common cardiovascular complication independent of coronary artery disease and hypertension．Trial to assess of myocardial injury in recipients of simultaneous pancreas and kidney transplantation by nuclear magnetic T２ mapping technology.
The arrhythmogenic right ventricular cardiomyopathy, also known as arrhythmogenic right ventricular dysplasia (ARVC/D) is a rare myocardial disease with a prevalence estimated to range from 1 case on 5000 persons in the general population. It have a dominant genetic transmission characterized by alterations of desmosomial proteins and predominantly affects the right ventricle. The morphological alteration of the myocardium characterized by fibro-fatty substitution predisposes to arrhythmic events that can be fatal and cause death especially in young people and athletes. International guidelines provide a classification that includes clinical and histological criteria for diagnosis based on fibrous tissue substitution, percentage and right ventricle localization. Indeed, it is mainly affected the right ventricle but in some cases also the left ventricle result involved and the fatty tissue or fibro-fatty tissue with particular arrangement may affect the full-thickness wall are pathognomonic. Authors identified 10 cases of arrhythmogenic cardiomyopathy in forensic autopsy collocated in the 2003 to 2017, included 8 males and 2 females. Their age ranged from 16 to 45 years with an average age of 28.8±8.1 years. However, authors would like to demonstrate that with ARVC/D cannot be include only cases with increased fibrosis and exclusive localization to the right ventricle nor even cases with electrocardiographic alterations and other evident clinical criteria. Indeed, in the analyzed cases authors observed an amount of fibrosis often less than the percentage reported in the literature and an involvement not only of the right ventricle but also of the septum and associated sinister ventricular modifications. To this must be added that the cases of death did not have a sudden death of relatives in family history as described in guidelines and therefore this criterion is not reliable for the purpose of a classification.
To determine the safety and efficacy of Amniotic and Umbilical Cord Tissue for the treatment of the following condition categories: Orthopedic, Neurologic, Urologic, Autoimmune, Renal, Cardiac and Pulmonary Conditions. The hypotheses are that the treatments are not only extremely safe, but also statistically beneficial for all conditions. Outcomes will be determined by numerous valid outcome instruments that compile general quality of life information along with condition-specific information as well.
The proposed study will investigate the clinical use of the ISCDX test that may differentiate between diverse stroke etiologies as listed below: Aim 1: Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out, as defined by TOAST classification of subtypes of acute ischemic stroke. Aim 2: In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability of biomarker blood tests to predict etiology between cardioembolic and large artery atherosclerotic.
We examined the feasibility and reliability of a combined echocardiographic and right heart catheterization (RHC) approach for right ventriculo/arterial (R-V/A) coupling assessment in HF patients with dilated cardiomyopathy (D-CMP).
Chronic kidney disease (CKD) is associated with a high risk of death and morbidity due to cardiovascular disease. Much of this is caused by left ventricular disease characterised by abnormal muscle thickness and scaring. This process appears to start early in the course of CKD and causes heart failure and dangerous abnormal heart rhythms. Previous work suggests that the process may be reversible by kidney transplantation but almost all of the studies are small, retrospective and lack scientific rigour. Furthermore, they almost all use echocardiography, which is inaccurate in patients with CKD. The investigators plan to perform the first large, prospective, controlled, blind-analysed study using cardiac magnetic resonance imaging to determine whether CKD associated cardiomyopathy is reversed by kidney transplantation and if so, whether factors such as blood pressure and mediators of metabolic bone disease/fibrosis are important in effecting this change. Greater understanding of the mechanisms responsible for CKD associated cardiomyopathy could lead to future strategies and treatments to improve the high cardiovascular mortality associated with this condition.
The purpose of this registry is to prospectively assess outcomes of device-treated ventricular tachyarrhythmias and all-cause mortality in non-ischemic cardiomyopathy patients indicated for ICD or CRT-D implantation for the primary prevention of sudden cardiac death. Differences in outcomes will be evaluated by sex and by device type.
Breast cancer patients undergoing trastuzumab-based HER2-directed therapy are at risk of heart function decline or heart failure symptoms, but it is unknown if, when, and for how long cardiovascular protective strategies, e.g. with a beta-blocker, could help. This study randomly assigns those taking curative-intent trastuzumab-based HER2-directed therapy to the beta-blocker carvedilol-either when significant heart function decline or subtle early signs of heart injury (either by elevation of a cardiac blood biomarker, i.e. cardiac troponin, or by an abnormal heart ultrasound marker, i.e. global longitudinal strain) are noted, or preventatively before beginning trastuzumab-based HER2-directed therapy. This study will further randomly assign those patients on carvedilol to either discontinuation at the end of trastuzumab-based HER2-directed therapy or continuation for another year, providing much needed clinical trial data on what the best strategy ("tactic") for those at risk of cardiotoxicity with trastuzumab-based HER2-directed therapy is.
