  • Strongly recommended

    Low-dose aspirin (usually 81 mg daily) is standard for you unless your doctor has specifically stopped it.

    Once you've had a heart attack, stroke, or stent, aspirin's benefit clearly outweighs its bleeding risk. This is one of the few places aspirin is still unambiguous. Don't stop it on your own — that carries real risk.
