[Coronary artery bypass grafting in octogenarian]

Area of Science:

• Cardiology
• Cardiac Surgery
• Geriatric Medicine

Background:

• Coronary artery bypass grafting (CABG) procedures in elderly patients are rising.
• Elderly individuals undergoing CABG face higher complication and mortality rates compared to younger patients.
• Octogenarians represent a growing demographic undergoing cardiac surgery.

Purpose of the Study:

• To evaluate the outcomes of isolated coronary artery bypass grafting (CABG) in octogenarian patients.
• To compare the results of CABG in patients over 80 years old with those aged 70-79.
• To determine if chronological age alone should be a contraindication for CABG in the elderly.

Main Methods:

• Retrospective analysis of 362 isolated CABG patients from January 1996 to December 1999.
• Patients were divided into two groups: 15 patients over 80 years old (80-year group) and 122 patients aged 70-79 years old (70-year group).
• Preoperative cardiac function (Canadian Cardiovascular Society class III or IV) was assessed and compared between groups.

Main Results:

• Preoperative cardiac function was significantly worse in the 80-year group (60% CCS class III or IV) compared to the 70-year group (29% CCS class III or IV).
• No significant differences were observed between the two groups regarding extracorporeal circulation time, aortic clamp time, number of bypasses, or postoperative complications.
• This suggests comparable surgical safety and outcomes for octogenarians and younger elderly patients undergoing CABG.

Conclusions:

• Coronary artery bypass grafting (CABG) is a safe and effective procedure for octogenarians.
• Chronological age alone should not be a reason to exclude octogenarian patients from CABG.
• Further research may explore long-term outcomes and specific risk stratification for this patient population.
