Filter by:The goal of this randomized controlled trial is to assess the effectiveness of ACE inhibitors versus standard care) in reversing asymptomatic heart failure (HF stage-B) and/or diastolic dysfunction during a two-year open-label treatment period for formerly preeclamptic women on: 1. Reversibility of structural and functional myocardial impairment in asymptomatic HF towards healthy values; 2. The progression from asymptomatic to symptomatic HF (symptoms scored based on the NYHA criteria); 3. Cardiovascular performance (volume- and pressure load), cardio metabolic risk factors (glucose metabolism, lipid status, kidney function) and quality of life (questionnaires); 4. Novel biomarkers and relevant microRNA's indicative for hypertrophy, fibrosis inflammation and ischemia. Eligible subjects will be counselled and upon informed consent randomized for either medication group (n=65) or care as usual group (n=65). After a complete cardiovascular assessment, medication will be initiated open-labeled (Perindopril 2 mg or no medication). Thereafter, standard medical check-ups (blood pressure, ECG, kidney function, transthoracic cardiac ultrasound, endothelial function, quality of life questionnaires, medical history taking, blood and urine banking) will be performed every six months for two years. Researchers will compare ACE inhibitor (Perindopril 2 mg) and care as usual (i.e. no medication) to investigate whether ACE inhibitor allows timely recovery after subclinical heart failure.
The present study is testing spermidine treatment in elderly patients with coronary artery disease. The study is a randomized, double-blind, placebo-controlled, two-armed, parallel-group, single centre, clinical study.
Myotonic dystrophy type 1 (DM1) is a neuromuscular disorder in relation with an unstable expansion of CTG repeat. Patients with DM1 are at risk of arrhythmia and conduction disorders. Mortality are mainly related to respiratory failure and sudden death. Patients with DM1 may suffer from obesity, arterial hypertension, diabetes mellitus and sleep apnea. These comorbidities are classically associated with left ventricular diastolic dysfunction (DD) . The investigators aim to assess the prevalence of left ventricular diastolic dysfunction in patients with myotonic dystrophy type 1 , the distribution of DD grading as well as the long-term prognosis of DM1 patients with a left ventricular diastolic dysfunction.
Diabetes mellitus people have a higher incidence of cardiovascular disease, and the results of cardiovascular events are worse. Heart failure and diabetes both have a worse prognosis, with a 1.5-2 times increased risk of death. Data from the literature have shown that MET lowers mortality by 14-35% in this patient population, which represents one-third of all HF patients with no increases in lactic acidosis incidence.
The aim of the study is to investigate sex-specific differences in LV and RV function (systolic and diastolic) with regarding the development and progression of heart failure with preserved ejection fraction based on a retrospective data analysis. Lifestyle modification factors will be assessed for multivariate analyses in order to detect influencing factors. Progression will be analysed in a retrospective time series analysis.
The goal of this study is to test the feasibility of guiding as-needed pharmacological rate control of atrial fibrillation (AF) by implantable cardiac monitors and to assess the impact of continuous beta-blocker therapy versus as-needed rate control on the following outcomes: (1) exercise capacity, (2) AF burden, (3) symptomatic heart failure, (4) biomarker assessment of cardiac filling pressures and cardio-metabolic health, and (5) quality of life in patients with atrial fibrillation and stage II or III heart failure with preserved ejection fraction.
The goal of this prospective, multicentre study is to investigate short- and long-term cardiovascular effects in cancer patients treated with immune checkpoint inhibitors (ICIs). The main question[s] it aims to answer are: - To investigate troponin and NT-proBNP values in patients receiving ICIs and their association with ICI-induced CV abnormalities and MACEs. - Study the calcium score, systolic, and diastolic (dys)function. - Evaluate associations between patient/disease characteristics / transthoracic echocardiography parameters / electrocardiography parameters and troponin / NT-proBNP levels. Participants will be closely monitored by performing the following additional visits and testing: - Chest CT scan prior to treatment start, after 12 and 24 months. - Consultation with a cardiologist at baseline, 3, 6, 12 and 24 months, who will perform an electrocardiogram and echocardiogram. - One additional blood sample prior to treatment start, after 3, 6, 12 and 24 months. An extra blood sample could be taken in case of sudden heart problems. - Non-invasive endothelial function tests prior to treatment start, after 12 and 24 months.
Sepsis is a life-threatening infection with increasing incidence, and its spectrum of disease can involve cardiac dysfunction, which further adds to mortality. Although cardiac involvement in sepsis has been classically attributed to systolic dysfunction, diastolic dysfunction is increasingly diagnosed due to new echocardiographic techniques and the conceptual evolution of diastolic dysfunction. Combining systolic and diastolic dysfunction assessment could lead to a better diagnosis of septic cardiac dysfunction. Furthermore, earlier forms of septic cardiac dysfunction could be more promptly recognized by measuring novel and less used parameters of diastolic dysfunction. We hypothesize that left atrium (LA) strain and isovolumetric relaxation time (IVRT) derived intervals could be new and earlier predictors of diastolic dysfunction in septic patients with a potential impact on clinical presentation and prognosis and that rare genetic variation associated with inherited cardiomyopathies could underline the risk and severity of sepsis-related myocardial dysfunction with potential impact on diagnosis and prognosis.
Cardiac magnetic resonance (CMR) imaging is excellent at assessing the contractility of the heart muscle. However, relatively little is known about CMR's ability to assess the relaxation (diastolic function) of the heart between heart beats, where echocardiography remains the gold standard. This is important because in 30% of heart failure patients the overwhelming problem is diastolic dysfunction, and so they often need both tests. The investigators wish to investigate how to best make measurements using CMR to identify those with impaired diastolic function, in the context of the current gold standard test (echocardiography).
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.
