[Aortocoronary venous bypass operation in the elderly]

Area of Science:

• Cardiovascular Surgery
• Geriatric Cardiology
• Clinical Risk Assessment

Context:

• Extended diagnosis for aorto-coronary venous bypass (ACVB) operations involves high-risk patients, including those with unstable angina pectoris (inApS), left main artery disease (LAD), and reduced ejection fraction.
• Preoperative risk stratification is crucial for identifying patients who may experience complications.

Purpose:

• To evaluate the perioperative risk and postoperative outcomes in patients aged over 60 undergoing extended ACVB operations.
• To compare complication rates and long-term quality of life between older and younger patient groups.

Summary:

• A study of 600 patients undergoing ACVB operations, with 150 high-risk patients monitored for complications, found that patients over 60 experienced increased rates of perioperative myocardial damage (PMD) and low output syndrome (LOS) (p < 0.001).
• Despite a higher incidence of PMD and LOS in older patients, hospital mortality was not significantly increased.
• Intensive therapeutic measures effectively managed these complications in the majority of older patients.

Impact:

• Urgent ACVB operations are strategically sound for improving quality of life and life expectancy in patients over 60, particularly those with inApS and LAD.
• Individualized intensive care can mitigate the increased perioperative risks associated with ACVB in elderly patients.
• The study highlights the importance of tailored management strategies for high-risk elderly patients undergoing complex cardiac surgery.
