question: My Mom is 83 years old and has had a bad cough for the past 4 weeks. The doctor did a chest x-ray and I have now been told she has an enlarged heart w/unfolding of the aorta. She has aphasia due to frontal lobe deterioration but otherwise is reasonably healthy. She takes low dose aspirin and has a B-12 shot every month. Thank you in advance for your help. Wendy
