Cardiovascular surgery in nonagenarians shows acceptable outcomes when considering frailty and activities of daily living (ADL). Careful patient selection is key for successful outcomes in this elderly population.
Area of Science:
- Cardiovascular Surgery
- Geriatric Medicine
- Surgical Outcomes
Context:
- Increasing elderly population in Japan.
- Advancements in cardiovascular surgery outcomes.
- Growing number of nonagenarians eligible for surgery.
Purpose:
- To evaluate the outcomes of cardiovascular surgery in nonagenarians.
- To assess the impact of frailty and activities of daily living (ADL) on surgical results.
- To determine the safety and efficacy of these procedures in the very elderly.
Summary:
- Six nonagenarians (mean age 90.8 years) underwent various cardiovascular surgeries.
- No 30-day or in-hospital deaths occurred; long-term survival was observed.
- Postoperative ADL initially declined but recovered to preoperative levels within one year.
Impact:
- Suggests nonagenarians can achieve acceptable outcomes with cardiovascular surgery.
- Highlights the importance of assessing ADL and frailty beyond chronological age.
- Provides evidence for considering surgical intervention in select very elderly patients.
