الإجابة: C. Aspirin is not recommended for primary prevention
He is 80, with no CVD, diabetes or risk factors, so aspirin would be primary prevention — and the cohort's CV risk lecture gives no recommendation for patients over 69 because of evidence of harm. Aspirin is far more effective for secondary than primary prevention.
- Option B (bleeding risk) is true and is the reason, but the overall advice to give is that aspirin is not recommended for him; A and D overstate its benefit.

Aspirin is far more effective in secondary than primary prevention, and in primary prevention trials the risk of harm outweighed the vascular benefit, so it does not clearly reduce MI risk here.

A true point (aspirin increases major bleeding: GI bleeds and hemorrhagic strokes), but it is only part of the answer. The consensus advice for this age group is not to use aspirin for primary prevention.

Aspirin works by irreversibly inhibiting COX-1, which lowers thromboxane A2 and platelet aggregation. It is an antiplatelet, not a drug that improves contractility or blood flow.
