Insights
Elderly patients undergoing coronary artery bypass graft (CABG) surgery face higher risks of major complications, longer hospital stays, and increased costs compared to younger patients. Careful preoperative evaluation and patient selection are crucial for this demographic.
Area of Science:
- Cardiology
- Geriatric Medicine
- Health Services Research
Background:
- Coronary artery bypass graft (CABG) surgery is a common procedure.
- The impact of aging on CABG outcomes requires further investigation.
Purpose of the Study:
- To assess early mortality, perioperative complications, hospitalization duration, and costs associated with CABG in elderly patients (≥65 years) compared to younger patients (≤60 years).
Main Methods:
- Retrospective analysis of patients undergoing CABG.
- Comparison of outcomes between elderly and younger patient groups.
- Detailed analysis of specific perioperative complications.
Main Results:
- Elderly patients had similar early (30-day) mortality but higher 120-day mortality (7.6% vs 1.3%).
- Elderly patients experienced a higher incidence of overall complications (62% vs 43%) and major complications (p=0.001).
- Increased intensive care unit stay, longer hospitalization, and greater costs were observed in the elderly group.
Conclusions:
- Elderly patients undergoing CABG face increased perioperative morbidity, longer hospital stays, and higher costs.
- Careful preoperative evaluation and patient selection are critical for optimizing outcomes in elderly CABG patients.
- Despite risks, CABG can significantly relieve symptoms in highly symptomatic elderly patients.
Abstract:
The purpose of this study was to document early mortality, perioperative complication rate, duration of hospitalization, and costs related to coronary artery bypass graft (CABG) surgery in the elderly. Arbitrarily, elderly patients were defined by age greater than or equal to 65 years; younger patients were less than or equal to 60 years old. A detailed list of specific perioperative complications was analyzed. Early (30-day) mortality was similar between groups, while 120-day mortality was higher among elderly compared with younger patients (7.6% versus 1.3%; p = 0.05). The number of elderly patients with 1 or more complications was also higher than among the younger patients (62% versus 43%; p = 0.05). When the incidences of atrial arrhythmias and transient psychoses were considered minor complications and excluded from consideration, the incidence of major complications was higher in the elderly: 41 major events among 76 younger surviving patients compared with 89 major complications in 61 older surviving patients (p = 0.001). Time spent in the intensive care unit and the duration of postoperative hospitalization were also greater in the elderly (p = 0.01 and p = 0.001, respectively). Finally, the elderly group incurred greater costs than the younger patients (p = 0.03). The likelihood of increased perioperative morbidity in elderly patients is documented in this study. Also, it appears that the increased frequency of complications in elderly patients is associated with a longer hospital stay and greater financial expense. Consequently, the careful preoperative evaluation of these patients, including cautious patient selection, assumes greater importance. After CABG procedures, the highly symptomatic elderly patient may experience dramatic relief of symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)
