Filter by:Heart failure is a condition in which the heart stops pumping effectively, causing symptoms such as breathlessness or leg swelling. It affects around 900,000 people in the United Kingdom. As our population gets older, this number will continue rise. It is a condition with poor overall survival - nearly 50% of patients die within 5 years of being diagnosed with heart failure. Cardiac cachexia is a complex condition associated with heart failure. There is general loss of muscle with or without loss of fat in cardiac cachexia. The main feature of cardiac cachexia is therefore unintentional weight loss in heart failure patients. The reason why it develops is poorly understood currently. Importantly, some studies have shown that cardiac cachexia is more likely to lead to poorer outcomes (such as death) in the patients who develop it. However, there have been no studies, to our knowledge, that look at this condition in those patients who have very weak hearts ('advanced heart failure'). The investigators are looking to clarify how common cardiac cachexia is within advanced heart failure patients, and secondly how outcomes compare to those advanced heart failure patients that do not have the condition. With this in mind, the investigators will be able to establish the fuller impact cardiac cachexia has on survival and outcomes in patients with advanced heart failure. This study will involve assessing a group of ~200 advanced heart failure patients for cardiac cachexia to establish an estimate of how common it is overall. The investigators will then follow up the patients over a year, to see if we can assess the impact of cardiac cachexia on survival and outcomes. Overall, the investigators therefore hope this study will give a more robust picture on the true impact of cardiac cachexia in advanced heart failure. By doing so, the investigators will firstly highlight its importance to other clinicians who will better be able to monitor and or diagnose it, and secondly pave way for more research on a potential treatment strategy for this condition.
Cardiac cachexia, the main feature of undernutrition in chronic heart failure, usually defined as a weight loss over 6% over 6 months, is a proven factor of morbidity and mortality in this disease. Its pathophysiology is complex, but proinflammatory cytokines seem to play a major role. Omega-3 poly-unsaturated fatty acids, present in fish oil, have proven beneficial in patients with coronary heart disease, due in part to their effects on membranes but also due to their anti-inflammatory effects, with inhibition of TNF-α and interleukins 1 and 6. The aim of this phase III randomized controlled double-blinded study is to assess the effects of 8 weeks of a omega-3-enriched protein-energy supplement versus an iso-energetic iso-nitrogenous supplement free of omega-3 fatty acids in cardiac cachexia. Thirty patients will be included in each group. The main judgment criterion will be maximum aerobic capacity (VO2 max), which best reflects aerobic capacity that correlates with muscle mass. Anthropometric, biological (nutritional, inflammatory and involved in food intake control), cardiac (functional) and quality of life will also be studied. All analyses will be performed in intention to treat. The investigators expect a significantly higher improvement of VO2 max in the omega-3 group. This study could lead to therapeutic advances in a frequent and severe disease.
The purpose of this study was to determine the effects of a high caloric drink on weight and several other clinical markers including quality of life in patients with unintentional weight loss (cachexia) due to chronic heart failure.
