NCT ID: NCT06129448 Completed - Clinical trials for Diabetes Mellitus, Type 1

Tumor Necrosis Factor-alpha Levels and Cardiac Functions in Type 1 Diabetes Mellitus

Start date: December 1, 2023
Phase:
Study type: Observational

The goal of this clinical trial is to learn about the effect of type 1 diabetes mellitus on cardiac functions and evaluate the correlation of the dysfunction with the tumor necrosis factor-α (TNF-α) an inflammation-related factor. The study population will be the patients with the diagnosis of type 1 diabetes mellitus and the healthy children es the control group. The main question[s] it aims to answer are: - Is diabetes affecting the systolic and diastolic cardiac functions - Is diabetes affecting the left and the right ventricles equally? - Does diabetes status, as assessed by HbA1c, have an impact on the occurrence of cardiac dysfunction? - Is TNF-α can be a marker for early diagnosis of cardiac dysfunction? Diabetic patients will be examined by both a pediatric endocrinologist and a pediatric cardiologist. Transthoracic echocardiography will be performed and TNF-α will be evaluated for both the diabetic patients and the healthy children.

NCT ID: NCT05519046 Recruiting - Heart Failure Clinical Trials

Cardiac Contractility Modulation in Chagas Heart Disease

FIX-Chagas
Start date: May 6, 2022
Phase: N/A
Study type: Interventional

Chagas disease is an endemic problem in Latin America, where millions of people are chronically infected with T. cruzi. Recently, it was assumed to have clinical and epidemiological relevance in several other countries due to migratory and globalizing social factors. CCC occurs in 30-50% of infected individuals, causing considerable morbidity/mortality rates. Heart failure is the most prevalent morbidity. While CRT and drug treatment have been advocated and implemented without much success to improve the clinical condition of patients with CCC, there is no consistent scientific evidence on the role of cardiac contractility modulation (CCM) as a form of adjuvant treatment for heart failure in patients with CCC. The hypothesis of this study is that patients with CCC, advanced heart failure, severe systolic dysfunction, and non-LBB have better clinical and functional responses when undergoing implantation of a CCM device than when undergoing cardiac resynchronization therapy.

NCT ID: NCT05408559 Recruiting - Clinical trials for Diastolic Dysfunction

Prevention of Age-associated Cardiac and Vascular Dysfunction Using Avmacol ES

CardiacAging
Start date: July 1, 2022
Phase: Phase 1/Phase 2
Study type: Interventional

Our local IRB approved clinical studies seeking proof of principle for the hypothesis that SFN can be safely administered to humans at doses sufficient to protect age-associated cardiac dysfunctions. Beneficial effects of SFN-therapy will be assessed by Pre- and post-intervention echocardiography, and exercise endurance at 0 and 24 weeks. Peripheral blood cells from treated and control subjects will be compared for mitochondrial respiratory function, oxidative damage, pro-inflammatory cytokines, and expression of antioxidant & anti-electrophile genes.

NCT ID: NCT05175066 Completed - Chemotherapy Effect Clinical Trials

Bisoprolol Administration to Prevent Anthracycline-induced Cardiotoxicity

Start date: November 12, 2020
Phase: Phase 3
Study type: Interventional

Anthracyclines are one of the most well-known and effective drugs used to treat malignancies.The most important limiting factor in the use of this drug is its cardiac toxicity which includes cardiomyopathy and congestive heart failure. Bisoprlol is a β1-specific β-blocker that can reduce cardiac overload and also have anti-inflammatory antioxidant effects and can reduce reactive oxygen metabolites so it can be used as a cardioprotective agent in patients with a high risk of heart failure. To the best of our knowledge, no study has been performed to evaluate the prophylactic effect of bisoprolol solely in patients under chemotherapy with anthracyclines. This study is aimed to evaluate the cardioprotective role of bisoprolol in patients with non-metastatic breast cancer receiving doxorubicin, by measuring global longitudinal strain before and after treatment.

NCT ID: NCT04476576 Recruiting - Cardiotoxicity Clinical Trials

Aerobic Exercise is Cardio-protective in Hemato-oncological Disease and New-onset Chemotherapy

AEROHEMONCO
Start date: March 2, 2021
Phase: N/A
Study type: Interventional

Oncological diseases are the main cause of death in developed countries and also in Uruguay. Advances in therapeutics have made possible to aspire to cure and in other cases long-term remission with a significant increase in survival and the transformation of cancer into a chronic disease. Chemotherapy treatments have some side effects and cardiotoxicity is well known within them. Heart failure (HF) is a progressive pathology, with high mortality and high resource requirements of the health system with a prognosis that may be worse than some types of cancers. The treatment of established systolic dysfunction and symptomatic HF is mainly based on the indication of inhibitors of the angiotensin-converting enzyme and beta-blockers among other pharmaceutical and no pharmaceutical interventions. Aerobic physical exercise, as a therapeutic intervention, reverses the physiopathological changes that are presumed to lead to HF in sedentary people and it is known, it is feasible to execute an exercise program in cancer patients. However, effective treatments for the primary prevention of systolic dysfunction are not well known. Our hypothesis is that an aerobic physical exercise program for at least 3 months, in subjects with lymphoma and new-onset chemotherapy, is effective in preventing left ventricular systolic dysfunction, at the end of chemotherapy and at one year. For this, the investigators propose a randomized, controlled, clinical study which is blind both for the patient and the evaluating physician, comparing the difference of global longitudinal strain (an echocardiographic result of myocardial function) pre-chemotherapy minus end of chemotherapy and minus one year after, between the active group (aerobic program) and the control group (flexibility program).

NCT ID: NCT03938090 Not yet recruiting - Heart Failure Clinical Trials

Optimised MultiSite Pacing Vector Study

Start date: July 2019
Phase: N/A
Study type: Interventional

The objective of this clinical investigation is to evaluate the clinical benefits of an MultiSite pacing (MSP) with patient specific left ventricular vector optimization in patients receiving cardiac resynchronization therapy (CRT) after 6 months of therapy. This clinical investigation is a single-center, prospective, two-arm, randomized 1:1, crossover study designed to evaluate the effectiveness of Optimized MSP CRT compared to conventional bi-ventricular pacing. Data will be collected at enrolment, CRT implant procedure, hospital pre-discharge, one, three and six months post implant. Enrolment data collection will include demographics, cardiovascular history, medication, echocardiography measurements, heart failure quality of life questionnaire and six minute walk test distance. CRT implant procedure data collection will include implanted system information, lead location and conduction times. The electrical conduction recording procedure will include surface ECG and device electrogram (EGM) recordings during various MSP vector pacing configurations at the time of CRT device implant. Patients will also undergo simultaneous invasive pressure measurements using a left ventricular pressure wire to allow haemodynamic measurements (dP/dtmax) during various MSP vector pacing configurations. Optimal MSP programming settings will be determined by the narrowest QRS duration recorded by 12 lead ECG and the greatest change in dP/dtmax by pressure wires study. In a subgroup of patients (approximately 25 patients), non-invasive electrical activation data will be collected with electrocardiographic imaging (ECGi) within 45 days of the implant procedure. Patients will then be randomized 1:1 to receive either standard biventricular pacing or Optimized MSP at their one-month follow-up (± 15 days) visit. At the 3 months (± 15 days) post randomization follow up visit, data collection will include surface ECG, EGMs, echocardiographic parameters and quality of life questionnaire. The patients will then undergo cross-over to the alternate randomization group with programming adjusted accordingly. At the final, 6 months (± 15 days) post randomization follow-up visit, data collection will include surface ECG, EGMs, echocardiographic parameters and quality of life questionnaire. This will mark the completion of the study for each patient. The expected duration of enrolment is 18 months. The total duration of the clinical investigation is expected to be 25 months.

NCT ID: NCT03755570 Suspended - Heart Failure Clinical Trials

How is COGNItive Function Affected by Cardiac Resynchronisation Therapy?

COGNI-CRT
Start date: June 21, 2019
Phase:
Study type: Observational

The primary objective of COGNI-CRT is to assess whether Cardiac Resynchronisation Therapy (CRT) can improve cognitive function in patients with systolic HF (LVEF ≤35%), when compared to a control group of patients implanted with an Implantable Cardioverter-Defibrillator (ICD) or a permanent pacemaker (PPM) with systolic HF (LVEF ≤35%). This clinical investigation is a prospective, single-centre cohort study. Each participant will be followed for 6 months. The study will collect data over 3 years; 2.5 years for enrolment and 6 months until the last participant completes the last 6-month follow-up visit. N.B: COGNI-CRT does NOT affect the patient's care pathway - the patients who will be selected for participation are those who have already been referred for the device implant. The ONLY difference to the patient's care pathway caused by COGNI-CRT is the addition of a battery of cognitive function tests, which involves asking the patient questions and asking them to complete questionnaire-like cognitive tests. NTpro-BNP levels, NYHA classification and LVEF will be measured prior to device implantation and at 6-months post-implant to assess the device's impact on the participant's heart failure (and CRT response). N.B: NT-proBNP, NYHA classification and LVEF are all parts of the patient's standard care pathway, COGNI-CRT is just utilising the data collected as part of the investigation. The main study arm and control group allows COGNI-CRT to assess 3 potential outcomes for patients with severe HF (LVEF <35%): 1. Cognitive function is not improved by CRT, ICDs or PPMs 2. Cognitive function can be improved by the assurance of rate control offered by CRT, ICDs and PPMs 3. Cognitive function can be improved by the assurance of ventricular synchronisation and rate control provided by the additional left ventricular lead in CRT devices.
