[Aortocoronary bypass surgery in patients older than 70 years]
Insights
Aortocoronary bypass surgery in elderly patients (70-81 years) shows acceptable risks and satisfactory long-term outcomes. This cardiac surgery significantly improves functional status, making it a viable option for older individuals.
Area of Science:
- Cardiovascular Surgery
- Geriatric Medicine
- Cardiac Surgery Outcomes
Context:
- Coronary artery disease management in the elderly is a growing concern.
- Surgical interventions for elderly patients require careful risk-benefit assessment.
- The study examines outcomes of aortocoronary bypass surgery in a specific elderly cohort.
Purpose:
- To evaluate the operative risk, survival rates, and functional status improvement after aortocoronary bypass surgery in patients aged 70-81 years.
- To assess the safety and efficacy of coronary artery bypass grafting (CABG) in an elderly population.
- To analyze postoperative complications and long-term results in geriatric cardiac surgery patients.
Summary:
- A 10-year study (1981-1990) included 204 patients aged 70-81 undergoing aortocoronary bypass surgery.
- Operative mortality was 6.8%, with 1- and 5-year survival rates of 92% and 86%.
- Postoperative complications included arrhythmias (19%), bleeding requiring reoperation (5.4%), and respiratory issues (13%). Significant improvement in New York Heart Association (NYHA) functional class was observed (p < 0.001).
Impact:
- Coronary artery surgery in the elderly demonstrates an increased but acceptable operative risk.
- Long-term results and postoperative functional improvement are highly satisfactory, supporting its use in selected elderly patients.
- The findings highlight the importance of considering CABG for improving quality of life in older adults with severe coronary artery disease.
Abstract:
From January 1981 to December 1990, 204 patients aged between 70 and 81 years underwent aortocoronary bypass surgery. Operative mortality (30-day mortality) was 6.8%. Actuarial survival rate at 1 and 5 years was 92% and 86% respectively. A higher incidence of postoperative complications was observed (arrhythmias in 19%, reoperation for bleeding in 5.4%, respiratory and neurological complications in 13% and 3% respectively, perioperative infarction in 4.4%). The mean follow-up was 25 months. Preoperatively most patients (71%) were in New York Heart Association (NYHA) functional class III and IV, and at the end of following-up in NYHA functional class I and II (95%) (p less than 0.001). A rapid rise in coronary artery surgery in the elderly is evident. It is associated with an increased but acceptable operative risk. Long-term results and postoperative improvement of functional status are very satisfactory.
