Hi, I have just a few questions. Do you know what kind of medications he s on? And what does it mean by another round? Severe chest pain? If your dad doesn t want to take his pills, his risk of heart attack, stroke, and cardiac surgery will increase significantly. Also, if he continues to have chest pain, maybe he should get an angiogram to see which, if any, coronary artieries are blocked. During an angiogram a fluid is injected into different parts of the heart under an x-ray in order to see blockages and other potential problems with the heart. If there are any, they may be able to stent it to open it back up, but it s always at risk of closing again if he doesn t take care of himself. Changing his lifestyle can help improve his condition.. Make sure he increases exercise gradually, because pushing himself can stress his heart even more and lead to a heart attack as well. Go for a walk w/ him, discourage his bad eating habits, whatever it takes. Good luck!!
