[The cardiac risk patient in anesthesia]

Area of Science:

• Anesthesiology and Perioperative Medicine
• Cardiology
• Geriatric Medicine

Context:

• Perioperative cardiac morbidity presents significant challenges for anesthesiologists.
• Increasing prevalence of coronary artery disease (CAD) in elderly populations elevates patient risk.
• The majority of at-risk patients lack preoperative CAD diagnosis.

Purpose:

• To outline strategies for managing perioperative cardiac risk in patients undergoing non-cardiac surgery.
• To review the utility of risk assessment tools and prophylactic therapies.
• To highlight interventions that may reduce cardiovascular complications.

Summary:

• The Revised Cardiac Risk Index is recommended for high predictive value in assessing patient and surgery-related risks.
• Further preoperative testing is advised for intermediate-risk patients with unclear functional status.
• Beta-blockers are recommended for prophylactic perioperative therapy, particularly in vascular surgery patients and those with poor functional status.
• Maintaining beta-blockade postoperatively for 5-7 days is crucial.
• Preventing perioperative hypothermia and utilizing thoracic epidural anesthesia may reduce cardiac risk.

Impact:

• Provides guidance for anesthesiologists to optimize cardiac risk assessment and management.
• Aims to improve patient outcomes by reducing perioperative cardiac morbidity and mortality.
• Emphasizes evidence-based strategies for safer surgical procedures in at-risk populations.
