Coronary artery bypass surgery in elderly patients
Insights
Coronary artery bypass grafting is safe for elderly patients, with a low mortality rate. This study shows age should not prevent older individuals from receiving this life-improving cardiac surgery.
Area of Science:
- Cardiology
- Geriatric Medicine
- Cardiovascular Surgery
Background:
- Coronary artery bypass grafting (CABG) is a common procedure for severe coronary artery disease.
- The safety and efficacy of CABG in elderly populations (≥65 years) require ongoing evaluation.
Purpose of the Study:
- To assess the outcomes of coronary artery bypass grafting in patients aged 65 and older.
- To determine if advanced age is a contraindication for CABG.
Main Methods:
- Retrospective review of 75 patients aged 65+ who underwent CABG over a 2-year period.
- Analysis of perioperative data, including mortality, graft numbers, blood transfusions, and hospitalization duration.
- Assessment of functional status (New York Heart Association class) pre- and post-surgery, with 1-year follow-up.
Main Results:
- A 4% mortality rate was observed in the elderly cohort.
- Average of 3.1 grafts per patient and 5.1 units of blood transfused.
- Postoperative hospitalization averaged 13 days.
- Significant functional improvement: 60 patients improved to NYHA Class I, 6 to Class II, 3 to Class III, and 1 remained in Class IV at 1-year follow-up. One patient died, and 4 were lost to follow-up.
Conclusions:
- Coronary artery bypass grafting can be performed with an acceptable mortality rate in elderly patients.
- Age alone should not be considered a contraindication for coronary artery bypass grafting.
- CABG offers significant functional benefits for older adults with coronary artery disease.
Abstract:
Seventy-five patients 65 years of age and older had coronary artery bypass surgery during 2 years at Scott and White Memorial Hospital with a 4 per cent mortality rate. An average of 3.1 grafts were placed and 5.1 units of blood were used during 13 days of postoperative hospitalization. Sixty-one patients were in New York Heart Association Class IV, 12 were in Class III, and 2 had other indications for coronary artery bypass. One year following surgery there were 60 patients in Class I, 6 in Class II, 3 in Class III, and 1 in Class IV; 1 patient was dead, and 4 were lost to follow-up. Our conclusion is that coronary artery bypass grafting can be performed with an acceptable mortality rate in the elderly and that age alone should not be considered a contraindication to the operation.
