Filter by:The purpose of the present study is to evaluate the safety and exploratory efficacy of the umbilical cord mesenchymal stem cells for patients with ischemic heart diseases.
Project aim is to quantify the influence of a severe therapy-refractory heart failure caused by ischemic or dilative myocardiopathy on the function of the diaphragm, its molecular biological parameters and on the M. vastus lateralis. The control group consists of patients with coronary artery disease (CAD) and normal left ventricular ejection fraction indicated for coronary artery bypass graft surgery (CABG) Differences in the geneses of heart failure (ischemic vs. dilative cardiomyopathy) will be evaluated during analysis. The ubiquitin-proteasome signaling pathway is considered as a central issue for the mechanism of the analyses muscle catabolism.
Pupose: Takotsubo cardiomyopathy is a rare and not well-known complication of the subarachnoid hemorrhage. This form of heart failure, called as "broke heart" or "apical ballooning syndrome", was first described by Japanese authors at the beginning of 1990's. 1.5-2.2% of acute coronary syndrome is Takotsubo cardiomyopathy. Its predisposing factors, hypothetical parthenogenesis, diagnostic criteria and therapeutic methods are already known from the literature. The study intends to include all patients over 18 years of age who were admitted to our clinic within 48 hours after the bleeding regardless of gender, neurological status or age. Data to be registered within 24 hours after admittance: Instruments: - Intracranial blood flow characteristics:TCCD - using Transcranial Color Doppler; systolic, diastolic and mean blood flow velocity, Systolic / Diastolic ratio, pulsatility index - ECG abnormalities: Corrected QT Interval (QTc), T wave, ST segment, arrhythmia - Echocardiography (Ejection fraction%, exact location and degree of cardiac wall motion abnormalities) - documented with video recording Hypothesis: The risk of Takotsubo cardiomyopathy (TS) is increased if SAH is associated with more severe state, a greater degree of bleeding, intraventricular and/ or intracerebral hemorrhage. The definitive care of patients is postponed due to the appearance of TS, which could affect the final outcome.
This study is an observational study to determine predictors of sudden cardiac death or appropriate ICD therapy in patients with non-ischemic cardiomyopathy. Patients will be followed for 36 months for the occurrence of sudden cardiac death
Paediatric long-term safety follow-up clinical trial in maximum 100 children with heart failure due to dilated cardiomyopathy or congenital heart disease, from 1 day to less than 12 years of age at recruitment into the preceding short-term pharmacokinetic (PK)/pharmacodynamic (PD) trials. Pharmacodynamic measurements and renal monitoring in all children after 1 , 4, 7 and 10 months of follow-up; in addition PK assessments as well as acceptability and palatability assessments in children still under enalapril Orodispersible Minitablet (ODMT) treatment.
Paediatric clinical trial in 50 children, from 1 month to less than 12 years of age, suffering from heart failure due to dilated cardiomyopathy, to obtain paediatric pharmacokinetic and pharmacodynamic data of enalapril and its active metabolite enalaprilat while treated for 8 weeks with enalapril in form of Orodispersible Minitablets (ODMTs), to describe the dose exposure in this patient population.
BACKGROUND: Chagas Disease (ChD) remains as one of the most neglected diseases in the world, with 8-10 million infected people and only one marginally effective therapeutic. The lack of good biomarkers for active infection or clinical end-points poses a problem for assessing the performance of new drugs or therapeutic interventions. Among the biomarkers, several studies showed that Brain Natriuretic Peptide (NT-ProBNP) is accurate maker of left ventricular systolic and diastolic dysfunction. OBJECTIVE: Our long term goal is to establish The Sao Paulo-Minas Gerais Tropical Medicine Research Center (SaMi-Trop) as a Center of Excellence for Neglected Infectious Disease Research in Brazil. The Specific Aims are to begin that process by focusing on Trypanosoma cruzi infection with the goal of finding an array of biomarkers that correlate with parasite persistence and Chagas cardiac disease status that can be used to infer risk of disease progression and death as well used as markers of cure (parasite eradication) or clinical efficacy (stabilize or reverse cardiac damage) of novel drugs METHOD: The investigators established a prospective cohort of 1,959 patients with chronic Chagas cardiomyopathy (CCC). The study is being conducted in 21 cities of the northern part of Minas Gerais state in Brazil, and includes a follow up of at least two years (baseline and 24 months) . The evaluation included collection of socio-demographic information, social determinants of health, health-related behaviours, comorbidities, medicines in use, history of previous treatment for Chagas Disease (ChD), symptoms, functional class, quality of life, blood sample collection and ECG.
The purpose of this study is to test the use of tolvaptan (commercial name Samsca) when given in addition to intravenous (IV) diuretics early during an episode of acute heart failure. It will be compared to a high dose of IV diuretics alone or the use of metolazone in addition to IV diuretics. The investigators are looking to see if there is improvement in the symptoms and outcomes of persons with acute heart failure.
Cardiac amyloidosis is a major cause of early treatment-related death and poor overall survival in individuals with systemic light chain amyloidosis. This project will develop a novel approach to visualize cardiac amyloid deposits using advanced imaging methods. The long-term goal of this work is to identify the mechanisms of cardiac dysfunction, in order to guide the development of novel life-saving treatments.
The aim of this study is to investigate the effects milrinon and levosimandan on n heart function in septic cardiomyopathy and how norepinephrine affects the left and right ventricular function in patients with septick shock using pulmonary artery catheter, conventional and strain echocardiography.
