I was informed this week that he has a heart blockage and next week he has an appointment with the cardiologist. If the heart stops, what will be the consequence to a brain already affected by ALZ. The NH just asked me the question if I want them to resuscitate or not. He already has his wishes for not to be kept alive artificially. Resuscitate if the heart stops? Do not resuscitate? Please help me understand the difference between his wishes or an unexpected heart stoppage. He never had heart problems before.
