The purpose of this study is to: * Evaluate the efficacy of nucresiran compared to placebo on reducing all-cause mortality and cardiovascular (CV) events * Evaluate the efficacy of nucresiran compared to placebo on additional assessments of CV events and/or death * Evaluate the efficacy of nucresiran compared to placebo on patient-reported health status and health-related quality of life
This will be a two-arm investigator-initiated randomized controlled study of patients with nHCM and LV ejection fraction ≥50% and NYHA II-III symptoms, normal intrinsic conduction system and pre-existing suitable dual-chamber implantable cardioverter defibrillators (ICD) systems. Patients will be randomly assigned to either personalized accelerated pacing (using the myPACE+ algorithm with mono-fractional exponent) or usual care groups. At baseline and after 3 months of pacing all patients will undergo a CPET, echocardiogram, blood work for NT-proBNP levels and complete the KCCQ-OSS and HCMSQ, questionnaires. The investigator team hypothesizes that personalized accelerated pacing will be safe and improve symptoms and heart-failure related quality of life, physical activity, pVO2, biomarkers (i.e. NT-proBNP), diastolic parameters and cardiac structure.
To evaluate the efficacy and safety of a single dose of NTLA-2001 compared to placebo in participants with ATTR-CM.
This study examines TRPC6 in predicting and preventing chemotherapy related cardiac toxicity and heart failure in patients with breast cancer. Cardiac toxicity, changes in heart function is a well-recognized complication of certain cancer related therapies. Understanding these changes may allow early intervention against therapy-related cardiac toxicity and also identify novel therapeutic targets to protect patient long-term cardiac health. Studying samples of blood from patients with breast cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA), identify biomarkers related to cardiac toxicity, and prevent the development of therapy-induced cardiac toxicity in patients receiving chemotherapy.
The purpose of this study is to test the safety and preliminary efficacy of AAVrh.10hFXN to treat the cardiomyopathy associated with Friedreich's ataxia (FA). AAVrh.10hFXN is a serotype rh.10 adeno-associated virus gene transfer vector coding for Frataxin (FXN). The drug is administered intravenously. This is a phase 1, open label, dose escalation study with a total of 25 participants.
The objective of this study is to collect information on patients with cardiomyopathy (CM) due to mutations in the MYBPC3 gene, to evaluate their disease course, burden of illness, risk factors for this disease, and the quality of life (QoL). This study will also collect information on treatments, procedures and outcome in infants and children up to 18 yrs who have this mutation.
This randomized pilot phase I trial studies the side effects of donor bone marrow derived mesenchymal stem cells in controlling heart failure in patients with cardiomyopathy caused by anthracyclines. Donor bone marrow derived mesenchymal stem cells may help to control symptoms of heart failure and improve heart function.
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 goal of this protocol is to obtain information from individuals with cardiomyopathy and from their families in order to elucidate the molecular genetics of this disorder. This will provide the basis for future genetic counseling as well as contribute to elucidating the biology of normal and abnormal cardiac function.
The goal of this clinical trial is to evaluate a novel imaging approach that combines hyperpolarized 13C pyruvate magnetic resonance imaging (HP-13C-MRI) and \[¹⁸F\]Fluorodeoxyglucose positron emission tomography (FDG-PET) in a single exam to improve the prognostic assessment of ischemic cardiomyopathy. The main questions this study aims to answer are: Primary Hypothesis: Can the simultaneous acquisition of HP-13C-MRI and FDG-PET data improve the metabolic, viability, and mechanical function assessment in ischemic cardiomyopathy? Primary Outcome Measure: To determine whether the combined HP-13C-MRI/FDG-PET approach provides better prognostic value for ischemic cardiomyopathy compared to current separate imaging modalities. Secondary Outcome Measures: Baseline metabolic and viability profiles in healthy individuals. Correlation of metabolic imaging with clinical outcomes in preoperative patients with low left ventricular ejection fraction (LVEF). Longitudinal changes in myocardial metabolism post-surgery. Study Design: This is a prospective, non-blinded, single-center study utilizing a hybrid PET-MR scanner for simultaneous imaging. Participants will be divided into three groups: Healthy subjects (n=6) with normal LVEF for baseline reference. Preoperative patients (n=6) with low LVEF due to ischemic cardiomyopathy undergoing coronary artery bypass grafting (CABG). Post-CABG patients (n=6 at 4-6 months, n=6 at 10-12 months) to evaluate post-surgical changes. Procedures: Undergo HP-13C-MRI and FDG-PET imaging in a single session. Blood samples for metabolic biomarkers (lactate, pyruvate, triglycerides, insulin, glucose). Standard clinical cardiac imaging (Echocardiography, SPECT Myocardial Perfusion Imaging).
