Hi,  my husband had a 4 way bypass surgery 8 years ago and last march he had a heart attack.  he has been feeling numbness on the left side of his chest, and last night he had a sharp pain on his chest which stopped after doing some breathing techniques.  Is that numbness related or sign of another heart attack?
Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would like to explain that it is very important perform as soon as possible a comprehensive evaluation of that chest numbness, as it may be related to a new ischemic heart event. So, I would recommend consulting immediately the nearest RE service for a physical exam, resting ECG and some blood tests (including cardiac enzymes CK-MB, Troponin). Remember that after 5 years venous bypass grafts are more susceptible to possible occlusion. Hope to have been helpful! Greetings!
