Coronary artery bypass surgery in elderly patients

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.
