Sarcopenia Adversely Affects Outcomes following Cardiac Surgery: A Systematic Review and Meta-Analysis

Area of Science:

• Cardiology
• Geriatrics
• Surgical Outcomes

Background:

• Sarcopenia is a degenerative condition involving loss of skeletal muscle mass and strength.
• Its impact on cardiac surgery outcomes is not well understood.
• This study investigates sarcopenia's effect on cardiac surgery results.

Purpose of the Study:

• To synthesize evidence on sarcopenia's impact on cardiac surgery outcomes.
• To determine if sarcopenia is associated with increased mortality after cardiac surgery.
• To assess sarcopenia's influence on functional recovery post-cardiac surgery.

Main Methods:

• Systematic review and meta-analysis following PRISMA guidelines.
• Searched EMBASE, MEDLINE, Cochrane, and Google Scholar databases.
• Included 12 studies with 2717 patients; analyzed mortality and functional outcomes.

Main Results:

• Sarcopenic patients had higher early and late mortality risks (OR 2.40 and 2.65, respectively).
• No significant difference in surgical time or infection rates.
• Sarcopenic patients experienced longer ICU stays, more renal dialysis, and longer intubation.

Conclusions:

• Sarcopenia is a significant risk factor for mortality after cardiac surgery.
• Patients with sarcopenia face poorer functional outcomes post-surgery.
• Preoperative assessment of sarcopenia may improve patient management.
