My mother is 86 years old and  needs open heart surgery.  She has 2 blockages is one artery 70%,   I am very concerned about the high risk of her dying having the  surgery, or also having a stroke.   She also  has a history of  dufficulty to stop bleeding.
Hello, I have gone through your query. At the age of 86 open-heart surgery definitely carries high risk.Therefore, you should opt for angioplasty instead of surgery, if lesions in artery are suitable for procedure.I also suggest that 70% block is borderline, so you must ask your treating doctor for increasing doses and optimizing medical management. Surgery should be last option that too if patient is willing. My best wishes Chat Doctor.
