Filter by:Overarching aim of project Performance and image enhancing drugs (PIEDs) are pharmacological agents acquired illicitly to improve physical strength and endurance as well as to obtain a leaner and more muscular appearance. Androgenic anabolic steroids (AAS) are the most frequently used PIED and include testosterone and its synthetic derivatives. However, PIEDs also include other hormones, e.g. growth hormone (GH), insulin-like growth factor I (IGF-I), glucocorticoids, insulin and thyroxin. Originally, the use of PIEDs was predominately restricted to elite athletes. However, today most users of PIEDs are recreational athletes. In USA, the prevalence of recreational PIED users (three million) exceeds the prevalence of type 1 diabetes. This appears to be the same in Denmark, where the estimated prevalence of recreational users of PIEDs is 44,000, compared to approximately 30,000 patients with type 1 diabetes. The access to AAS is easy due to the unregulated and illicit sale on the internet. Furthermore, PIED use is common in the young population with possible detrimental effects on future health and well-being. PIEDs are linked to premature death and a wide spectrum of somatic and psychological disorders. However, clinical data on the use of PIEDs is currently limited. Randomized trials of PIEDs are unethical as this would require administration of potentially harmful supra-physiological doses of hormones and this is the rationale behind our proposal to perform an observational study. With this project the investigators propose to a) Perform a cross-sectional nationwide study of current and former users of PIEDs (N=1200), focusing on AAS. In particular, the investigators will pay attention to: 1. Preclinical cardiovascular disease 2. Psychological well-being, aggression and quality of life 3. Biomarkers of ageing 4. Body composition and muscle strength b) Establish a nationwide biobank containing blood, urine and hair samples from current and former users of PIEDs.
Patients who have a heart attack are at high risk for future development of heart failure ('weakening of the heart'). The researchers believe that the reaction of the heart muscle to injury (inflammation) during a heart attack may be contributing to the risk of heart failure. The current study will test the ability of an anti-inflammatory medicine (anakinra) to block the inflammation in the body during and after a heart attack.
There is an increasing interest in the use of metformin in CV diseases and there is an increasing interest in studying its potential new roles in heart failure patients. There were some concerns related to the safety of metformin in such diabetic patients due to the risk of lactic acidosis. However, recent studies showed that metformin was safe or even beneficial in HF patients. We hypothesized that metformin might improve morbidity, mortality, cardiac function, and HR-QoL in non-diabetic patients with HFrEF.
This study is a prospective, multi-center, open label, randomized clinical trial conducted in the republic of Korea. The objective of this study is to evaluate the efficacy and safety of the treatment using home bioelectrical impedance analysis (BIA) and linked application system in patients with heart failure (HF).
Observational multicenter registry of cohorts with follow-up. Patients with heart failure, age ≥ 18 years, with clinical suspicion of cardiac amyloidosis and any LVEF value, treated in the field of Internal Medicine. Initially, a duration of two years was established to recruit at least 150 patients in the group with AC, and a follow-up of two years. Upon completion of the two years of follow-up, the continuity or completion of the registry will be assessed.
The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.
This is a prospective pilot study to evaluate changes before and 4 weeks after beta-blocker withdrawal in 30 HFpEF patients.
The objective of this study is to prospectively compare decongestive therapy administered by the Reprieve DMS system to Optimal Diuretic Therapy (ODT) in the treatment of patients diagnosed with acute decompensated heart failure (ADHF). The main objective is to determine if the Reprieve DMS can more efficiently decongest ADHF patients in comparison to Control Therapy.
The purpose of this study is to test a clinical decision support (CDS) tool that provides clinicians (cardiologists and nurse practitioners) medication recommendations regarding guideline directed medical therapy (GDMT) in patients with heart failure and reduced ejection fraction (HFrEF).
There is limited long-term evidence specific to AAs with HFrEF on sacubitril/valsartan therapy. Plasma NT-proBNP levels are lower in AA individuals as compared to Caucasian individuals in general. However, the mechanism of action of sacubitril specifically targets the activity of BNP. Therefore, there is the potential that the mechanism of action of sacubitril/valsartan may be less effective in AAs.
