question: I was recently told I have an enlarged ascending aorta, 4.0 cm. I had a CT scan done and an ultrasound, haven t been back for results yet but am terrified I ll be told I need open-heart surgery. I had friend who died after open-heart surgery, I don t think I can do it. Are there any other options? Im 25 lbs overweight but all my lab results are normal. Can I do moderate exercise? I m 64 years old and have had moderately controlled high blood pressure for years. Thank you
