I just know my dad was at like 70% blockage and had to have 5 by-passes done and he never had a heart attack. ๐คทโโ๏ธ I guess every situation is different. My dad also had heart disease so I don't know if that affects the course of treatment or not.
Yeah, i have a co-worker who's father had blockages and he had 5 by-pass as well. I guess thats more to prevent a heart attack down the road and/or to fix heart damage that might already be present through heart disease. Im also not a doctor so I guess every case is different and every doctor/hospital address things things differently.
