Filter by:Cirrhotic cardiomyopathy is associated with increased risk of complications like hepatorenal syndrome, refractory ascites, impaired response to stressors including sepsis, bleeding or transplantation, poor health related quality of life and increased morbidity and mortality. Left ventricular diastolic dysfunction (LVDD) is associated with risk of hepatorenal syndrome (HRS) , septic shock. , heart failure in the perioperative period following liver transplantation, and after trans-jugular intrahepatic portosystemic shunt (TIPS) insertion . The echocardiographic E/e' ratio is a predictor of survival in LVDD, with multiple studies, including prospective data from our Centre.

The purpose of this study is to learn about the safety of Tafamidis for the treatment of Transthyretin amyloid cardiomyopathy (ATTR-CM) in India. ATTR-CM is a condition that affects people's hearts. Transthyretin is a protein that is made in the liver. In some people this protein stops working and forms clumps called as amyloid. Transthyretin amyloid builds up in heart and stops the heart from pumping properly. This study is seeking for participants who are: - confirmed with ATTR-CM. - given Tafamidis capsules to be taken by mouth. The safety of Tafamidis capsules will be checked based on side effects. These side effects can happen within 6 months after taking Tafamidis. A side effect is something (expected or unexpected) that you feel was caused by a medicine or treatment you take. The study doctor will collect side effect information and put the information on patient's case form. Follow-up of the patient's will be performed via clinic re-visit or over a call. It is not a rule for the participants to visit the clinic in this study. This study will help to see if Tafamidis is safe.
This study is a single-arm, open-label, dose-escalation trial aimed at determining the optimal biologically active dose (OBD) of YOLT-201 and providing safety and efficacy evaluation. The OBD is the dose at which serum transthyretin (TTR) protein baseline reduction is ≥60% but not exceeding 95% after 28 days of dosing. The OBD dose should not exceed the maximum tolerated dose (MTD), defined as the highest dose at which no more than one subject experiences dose-limiting toxicity (DLT) within each cohort.
This clinical trial will study the effects of aficamten (versus placebo) on the quality of life, exercise capacity, and clinical outcomes of patients with non-obstructive hypertrophic cardiomyopathy.
The purpose of this study is to investigate whether there are differential expressions of molecules in the kallikrein-kinin system (KKS) pathway in septic cardiomyopathy, and to analyze their regulatory mechanisms and gene expression changes.
The goal of this prospective cohort study is to evaluate the neurologic changes in patients that received transapical beating-heart septal myectomy. The main questions are: whether this novel operation way would cause neurologic impairment; whether this novel operation way have similar neurologic lesions, compared to other cardiac surgery ways. Participants will undergo detailed neurologic and cognitive assessment at baseline, after procedure, and at 30 days. Researchers will compare the clinically relevant manifestations and brain lesions measured by cognitive evaluation forms of the nervous system (i.e. Montreal cognitive assessment) and diffusion-weighted magnetic resonance imaging (DW-MRI) to assess the safety of transapical beating-heart septal myectomy on nervous system.
Prospective, randomised, multicentre, open-label study to assess the non-inferiority of a personalised precision strategy for Sudden Cardiac Death (SCD) prevention in patients with non-ischemic dilated cardiomyopathy with Left Ventricular Ejection Fraction (LVEF) ≤35%
Guidelines for patients having first-time implants advocate that even when heart function is only mildly impaired, modern pacing approaches should be utilised to avoid the potentially damaging effects of RV pacing to preventing symptoms from pacing induced or worsened cardiomyopathy. However, once a traditional (RV) pacemaker is implanted, development of impaired heart function does not prompt a device upgrade. Even at the end of battery life, physicians simply replace it like-for-like. This trial tests whether such patients have better symptoms and quality of life if changed to a modern physiological pacing strategy from the traditional RV pacing approach. In this crossover trial, participants will be upgraded to a physiological pacing strategy. After their procedure, they will have a one-month run-in period to recover from the procedure (their pacemaker will be programmed to continued RV pacing). They will be have 2 one-month blinded time periods, randomised to physiological pacing or right ventricular pacing alternately. They will subsequently undergo two six-month blinded randomised time periods. Patients will document symptoms monthly on a mobile phone application or computer. At the end of each time period, they will have measurements of heart function, a walking test and quality-of-life questionnaires including the SF-36 questionnaire. The investigators hypothesise that upgrading to physiological pacing strategies will improve patients' quality of life.
Amyloidoses are systemic or acquired disorders characterized by the deposition in the extracellular spaces of amyloid fibers formed by proteins codified by mutated genes or non-mutated but misfolded proteins. Cardiac involvement in amyloidosis is an important determinant of the clinical presentation and can be found in patients with amyloid light-chain (AL) or transthyretin (ATTR) amyloidosis, the latter due to the deposition of normal proteins (formerly known as senile amyloidosis) or mutated proteins. Cardiac amyloidosis (CA) has a poor prognosis that further worsens if the diagnosis and treatment are delayed. Nuclear medicine techniques have emerged as important tools for the diagnosis and characterization of CA. It has been recently demonstrated that cardiac uptake of bone tracers allows to identify the deposition of transthyretin in the heart, while it is not useful for the diagnosis of AL-CA, which currently requires the histological demonstration of amyloid fibers in a tissue sample taken with invasive procedures such as an endomyocardial biopsy. Recently, some PET tracers developed to identify beta-amyloid deposits in the brain proved able to detect an uptake even in the heart; nonetheless their possible use to diagnose CA is still debated. One of those tracers is florbetaben labelled with 18F, which displays a high binding affinity with beta-amyloid in the brain, while the experience on its use to identify extracranial amyloid deposits is still limited. Three studies have reported a cardiac uptake of 18F-florbetaben in AL or ATTR amyloidosis. Tracer uptake could be detected starting from 15 minutes after tracer administration. In a case series of 60 patients (20 with AL-CA, 20 with ATTR-CA and 20 with CA suspected but excluded) we demonstrated that the evidence of a myocardial uptake in a late acquisition can effectively discriminate AL- from ATTR-CA or other conditions. Indeed, patients with AL-CA displayed an intense and persistent myocardial uptake in static acquisitions at all time points, while patients with ATTR-CA and those without CA displayed a rapid reduction of the uptake after the early acquisition. This study aims to compare the performance of PET/CT with 18F-florbetaben to diagnose AL-CA compared with the current diagnostic standard, which requires a tissue biopsy. Primary objective: To define the agreement (with its 95% confidence interval) between two diagnostic approaches to the diagnosis of AL-CA in patients with a monoclonal protein: the traditional invasive approach and a non-invasive approach using the visual assessment of 18F-florbetaben PET/TC. Secondary objectives: - To define the diagnostic performance of PET/CT with 18F-florbetaben (visual evaluation) in terms of sensitivity, specificity, positive and negative predictive value; - To define cut-offs from myocardial uptake quantification to confirm or discard AL-CA among patients with suspected CA and a monoclonal protein, compared to the standard diagnostic algorithm, from quantitative uptake values; - To assess the changes in the degree of myocardial 18F-florbetaben uptake over 12 months in patients with AL-CA; - To assess the safety and tolerability of PET/CT with 18F-florbetaben in patients evaluated for suspected CA.
