Sarcopenia and Cardiovascular Diseases

Area of Science:

• Gerontology
• Muscle Physiology
• Cardiovascular Medicine

Background:

• Sarcopenia is characterized by loss of muscle strength, mass, and function.
• It is often exacerbated by chronic conditions like cardiovascular disease, kidney disease, and cancer.
• Sarcopenia is linked to accelerated disease progression, increased mortality, falls, and reduced quality of life, particularly in older adults.

Purpose of the Study:

• Define sarcopenia in the context of muscle wasting disorders.
• Summarize associations between sarcopenia and cardiovascular diseases.
• Outline diagnostic and management strategies for sarcopenia.

Main Methods:

• This review synthesizes existing literature on sarcopenia.
• It examines the pathophysiologic mechanisms, including anabolic-catabolic imbalance and neuronal degeneration.
• Diagnostic and management approaches are discussed based on current evidence.

Main Results:

• Sarcopenia's development is influenced by aging, chronic illness, malnutrition, and immobility.
• Screening is crucial for individuals with chronic diseases.
• Body mass index is an inadequate screening tool due to sarcopenic obesity.

Conclusions:

• Early recognition of sarcopenia allows for interventions to potentially reverse or delay muscle disorder progression.
• Managing sarcopenia may positively impact cardiovascular outcomes.
• Further research is needed to address knowledge gaps and advance the field.
