Lyn, it depends on whether he has had an "event" (heart attack or tia or stroke) before. For every 3000 people who have not had an event before, taking aspirin will prevent one heart attack in a man and one ischaemic stroke in a woman. But three people are likely to be admitted with a gastric bleed. Also a higher incidence of indigestion . So in those circumstances, many doctors are stopping low dose aspirin as more people are hospitalised with side effects, than with what they were trying to prevent. In people who have already had a heart attack or stroke, the odds are better at secondary prevention, and so it is recommended that they carry on taking it.
Your dad should talk to his doctor before he stops taking any medication, but if he has not had a previous event, , I wouldn't worry too much.
