Heart Failure (HF) in elderly patients is a systemic syndrome where advanced age, comorbidities with organ system deterioration, frailty and impaired cognition significantly impact outcome. Cardiac cachexia, sarcopenia and frailty despite overlap in definitions are different clinical entities that frequently coexist in HF patients. However, these co-factors often remain unaddressed, resulting in poor quality-of-life, prolonged physical disability and exercise intolerance and finally with higher rehospitalization rates and mortality. Strategy aim to increase muscle mass and muscle strength and delay the occurrence of frailty state appear essential in this regard. Common HF drugs therapy (b-blockers, angiotensin-converting enzyme inhibitors) and prescription of physical exercise program remain the cornerstone of therapeutic approach in HF patients with new promising data regarding nutritional supplementation. However, the treatment of all these conditions still remain debated and only a profound knowledge of the specific mechanisms and patterns of disease progression will allow to use the appropriate therapy in a given clinical setting. For all these reasons we briefly review current knowledge on frailty, sarcopenia and cachexia in HF patients with the attempt to define clinically significant degrees of multiorgan dysfunction, specific "red alert" thresholds in clinical practice and therapeutic approach.
Core Tip: The last heart failure (HF) guidelines of the European Society of Cardiology dedicate a chapter each for cachexia, sarcopenia and frailty and several studies regarding these topics are coming up. This wealth of information highlights the importance of these co-factors in HF management and are each uniquely relevant to evaluate older patients with HF. It is time to routinely assess cachexia, sarcopenia and frailty that could help in personalized care plan, improve outcomes and reduce hospitalization and institutionalization. However, definitions, pathophysiology and treatment of all these conditions still remain unclear and we briefly summarize the most recent knowledge available in literature.
