Summary

Elderly patients over 65 undergoing coronary artery bypass grafting showed similar safety and effectiveness compared to younger patients. This surgery significantly improved angina symptoms in 93% of older individuals, highlighting its value in geriatric cardiac care.

Area of Science:

  • Cardiovascular Surgery
  • Geriatric Cardiology
  • Outcomes Research

Background:

  • Coronary artery bypass grafting (CABG) is a common treatment for coronary artery disease.
  • The safety and efficacy of CABG in elderly populations require specific evaluation.
  • Previous studies have varied in their assessment of outcomes for older patients undergoing CABG.

Purpose of the Study:

  • To compare the outcomes of coronary artery bypass grafting in elderly patients (≥65 years) versus younger patients.
  • To assess the prevalence of specific pre-operative conditions in elderly patients undergoing CABG.
  • To evaluate the impact of CABG on angina symptoms and overall outcomes in the elderly population.

Main Methods:

  • Retrospective comparison of 111 elderly patients (≥65 years) with 548 younger patients who underwent CABG between 1980 and 1985.

  • Analysis of pre-operative characteristics, including demographics, angina status, coronary artery disease extent, and left ventricular function.
  • Assessment of operative morbidity, mortality, and long-term angina symptom relief at follow-up.

    • Main Results:

    • Elderly patients exhibited a higher prevalence of female sex, unstable angina, left main coronary artery disease, and depressed left ventricular function.
    • No significant differences were observed in operative morbidity or mortality between the elderly and younger patient groups.
    • Angina was abolished or improved in 93% of elderly patients post-CABG, demonstrating significant symptom relief.

    Conclusions:

    • Coronary artery bypass grafting is a safe and effective treatment option for elderly patients with coronary artery disease.
    • The procedure yields comparable operative risks and mortality rates to younger patients.
    • CABG plays a crucial role in managing angina and improving quality of life for geriatric patients.
