In older patients undergoing CABG, what consideration influences the choice of arterial grafts?

• A. Comorbidity and functional status influence the decision
• B. Age alone determines graft choice
• C. They are always chosen due to patency
• D. They should never be used in older patients

Answer: (A)

The main idea being tested is that the choice of arterial grafts in older CABG patients is driven by the patient’s overall health and functional status, not by age alone. Arterial grafts offer better long-term patency, which is valuable for many patients, but older individuals often have comorbidities such as diabetes, vascular disease, kidney or lung problems, and frailty that increase surgical risk and influence how long they are expected to benefit from a graft. If the patient’s comorbidity burden and functional status make a longer, more complex procedure risky, a more conservative graft strategy may be chosen. Conversely, a robust older patient with good functional status and reasonable life expectancy might benefit from using arterial grafts to maximize long-term patency.

Age by itself is not the sole determinant; patency is important but must be weighed against operative risk and expected benefit. Arterial grafts are not never-used in older patients, and they are not chosen automatically just because they have good patency.
