[|Human|] My brother-in-law is about 64 years old and had a mild heart attack six months ago. He is under treatment and is doing ok. Can he climb stairs to reach his apartment on the third floor? No lift is available in the building. Thank you.  YYYY@YYYY
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that there is no harm in doing normal physical exercise and daily activities (including climbing stairs) in his clinical situation. So don't worry about it. You should know that physical exercise is recommended in these situations, to reduce his cardio vascular risk. Besides, I recommend continuing his actual therapy (preventive therapy including aspirin, a statin and antihypertensive therapy) and perform periodically scheduled follow-ups (with resting ECG and cardiac ultrasound) every 6-12 months. Hope to have been helpful! Best wishes!
