View clinical trials related to Cardiotoxicity.
Filter by:As the cancer-related prognosis improves thanks to recent advances in cancer-targeted therapies, the prognostic burden of chemotherapy-related complications - including cardiotoxicity - is increasingly recognised. So far, the evidence supporting pharmacological preventive strategies in cardio-oncology has been inconsistent and conflicting, and there is a clear need for well-designed trials with novel interventions. In this study, by using cardiac magnetic resonance, the investigators want to assess if a commonly used beta-blocker with a unique pharmacological profile, i.e. nebivolol, can prevent cardiac dysfunction in patients with breast cancer or diffuse large B-cell lymphoma undergoing chemotherapy with anthracyclines.
Cardiological complications of oncological treatment, including the most serious of them cardiotoxicity and heart failure, constitute a significant and still unsolved clinical problem. A history of hypercholesterolaemia and coronary artery disease in cancer patients, is one of the risk factors for cardiotoxicity. In recent years, a protective effect of statin treatment on the development of heart failure in cancer patients has been observed. ANTEC (Atherosclerosis iN chemoTherapy-rElated Cardiotoxicity) is a prospective observational study aimed at assessing the impact of the advancement of atherosclerotic lesions in the coronary arteries assessed in computed tomography on the development of left ventricular systolic dysfunction in cancer patients at high risk of myocardial damage. A group of 80 patients diagnosed with cancer before starting high-dose anthracycline chemotherapy (doxorubicin ≥ 240 mg / m2 or epirubicin ≥ 600 mg / m2 body weight), without a history of heart failure and coronary artery disease, will be included in the study. The total follow-up of patients was planned for 12 months. The primary endpoint is time to onset of left ventricular systolic dysfunction as assessed by echocardiography. The secondary composite endpoints include all-cause death, cardiovascular death, myocardial infarction, and stroke. Additionally, the assessment will include: the severity of atherosclerotic changes in the coronary arteries and the calcification index in computed tomography, the percentage decrease in left ventricular ejection fraction, GLS (global longitudinal strain) in echocardiography, and changes in the concentration of biomarkers involved in inflammatory and atherosclerotic processes. This is the first study of this type, which we hope will contribute to a better understanding of the pathophysiology of cardiotoxicity development and to changing the standards of management of oncological patients and improving survival in this group of patients.
Anthracyclines treat up to 60% of childhood malignancies with remarkable improvements survival rates. Unfortunately anthracyclines are associated with an increased cardiomyopathy risk. One study showed an almost six-fold greater risk of developing cardiomyopathy compared to sibling controls. A retrospective pilot study showed evidence of subclinical dysfunction (including impaired global longitudinal strain) in 42/52 childhood cancer survivors. There is limited research in this area, therefore current guidelines are based on expert opinion alone and lack consensus. Current methods of detection diagnose cardiomyopathy at an irreversible stage i.e. when the compensatory mechanisms are exhausted and the left ventricular ejection fraction impaired. Small trials have shown that early treatment with standard heart failure therapy may reverse damage, further validation is however required in this cohort. Newer techniques such as tissue doppler and strain rate imaging have shown promise for early prediction of cardiomyopathy in adult studies. Biomarkers such as troponin and NT-proBNP have also shown a correlation with cardiomyopathy. This study (n=208) aims to use echocardiography, strain imaging, holter monitoring and MRI for early detection of cardiomyopathy. Biomarkers, both currently used (for example, troponin and NTproBNP,) and more novel (for example, IL6, MPO, and sST2) will be assessed to see if early cardiomyopathy can be predicted. This study will explore biomarker discovery by analysing an age/gender matched subgroup for the top differentially expressed microRNA and protein biomarkers. Selected biomarkers will then be validated in a larger cohort.
Investigators will evaluate the safety and feasibility of a biomarker-guided cardioprotection strategy using NTproBNP, as compared to usual care, in breast cancer and lymphoma patients treated with anthracyclines.
Cardiovascular disease (CVD) is a major contributor to morbidity and mortality in pediatric, adolescent and young adult (AYA) cancer survivors (hereafter referred to as PAYA-CS). Exercise is a cornerstone of CVD prevention and treatment; yet, exercise has not been adopted as a standard of care in PAYA-CS at high CVD risk. The HIMALAYAS trial is designed to evaluate the feasibility and preliminary impact of an exercise-based CR on cardiovascular (CV) and psychosocial health, as well as CVD risk, in PAYA-CS with mild heart dysfunction (stage B heart failure (SBHF)). The primary objective of the HIMALAYAS pilot study is to assess the feasibility of a two-phase randomized controlled trial designed to evaluate impact of a 'CR-like' cardio-oncology rehabilitation (CORE) intervention on CV, psychosocial, and behavioural outcomes at 6 and 24 months, compared to behavioural support only (Support) in PAYA-CS. Screened PAYA-CS without SBHF and those with SBHF who do not participate in the RCT will be enrolled in a passive behavioural support (Support) group. The primary outcome is study feasibility, defined according to three primary criteria (i.e., participant recruitment, safety, and adherence). Secondary outcomes include additional feasibility metrics (e.g., intervention safety and tolerability) and exploratory efficacy outcomes including peak cardiorespiratory fitness (VO2peak), cardiac function (e.g., global longitudinal strain (GLS)), CVD risk factor control (e.g. insulin resistance), and patient-reported outcomes (e.g. anxiety). Our central hypothesis is that the conduct of a larger RCT comparing the impact of CORE versus non-intervention control will be feasible indicated by the achievement of our primary feasibility criteria. Our exploratory hypothesis is that we will generate preliminary evidence that CORE can improve VO2peak, cardiac function, CVD risk factor, and patient-reported outcomes over 6- and 24-month timepoints, relative to control.
The investigators will identify 10 patients in the department of radiation oncology who will receive standard of-care radiation therapy, and the treating radiation oncologist anticipates a mean left ventricular dose of at least 5 Gy. Patients will be evaluated by CMRI before and within one week of the completion of RT. We will compare the pre- and post-RT CMRI scans to identify changes related to radiation exposure. Our primary endpoint will be changes in myocardial strain. Secondary endpoints will include other CMRI parameters.
This is a companion study to the "Pragmatic Randomized Trial of Proton vs Photon Therapy for Patients with non-Metastatic Breast Cancer Receiving Comprehensive Nodal Radiation: A Radiotherapy Comparative Effectiveness (RadComp) Consortium Trial" (NCT02603341). The investigators will collect cardiovascular (CV) biomarkers and echocardiograms prior to, during, and for up to 1 year following radiation for a subset of patients enrolled on RadComp and to evaluate the impact of proton vs photon radiation therapy (RT) on CV function and structure.
Aluminum phosphide (AlP) or rice tablet is a cheap pesticide. When it comes in contact with acid (gastric acid) or moisture, it releases phosphine (PH3) gas. The heart,lungs, liver are the main targets in acute Aluminum phosphide (AlP) poisoning. Most deaths occur due to cardiovascular toxicity.
Patients enrolled in the study will receive standard of care adjuvant or definitive breast, chest wall or thoracic radiation therapy.Cardiac mitochondrial dysfunction is a hallmark of radiation-induced cardiac injury. Reactive oxygen species (ROS) produced by ionizing radiation cause oxidation of mitochondrial proteins and alter oxidative phosphorylation and pyruvate metabolism(5). The goal of this study is to detect early changes in the mitochondrial metabolism in situ as a marker for subclinical radiation-induced cardiotoxicity.
Over 50% of the more than 270,000 childhood cancer survivors in the U.S. have been treated with anthracyclines and thus are at risk of developing cardiotoxicity. The impact of exercise training on LV structure has been extensively studied. Left ventricular hypertrophy and cardiac chamber enlargement with the accompanying ability to generate a large stroke volume are direct results of exercise training. Aerobic exercise therapy offers a non-pharmacological mechanism to modulate multiple gene expression pathways that may promote cardiac remodeling. No prior studies have investigated the efficacy of aerobic exercise in the prevention or treatment of anthracycline-induced cardiotoxicity. We hypothesize that exercise intervention leads to a reverse in adverse cardiac remodeling with improvement of global and regional myocardial function in patients exposed to anthracycline.
