Hi I am a 40-year-old male. My job profile doesn't involve a desk job but is a field job. I am lean and have an active lifestyle. However my cholesterol reading is 300 mg/dl. Does it indicate that I can have a heart attack? Can a lean person with active lifestyle also have a heart attack Please help. The query is answered by Dr Santosh Kumar Dora Cardiac Electro Physiologist Asian Heart Institute (AHI) Mumbai. According to Dr Dora any person can have a heart attack. It does not depend only on cholesterol or body mass but multiple risk factors.
