The American Heart Association offers these suggestions:

• Offer plenty of support and encouragement, and look for support groups for both of you to join.
  
  
• Go along for doctor appointments. Ask questions and take notes, in case there are questions later.
  
  
• Give an honest report to the doctor about how your loved one is feeling, and how well he or she is following instructions.
  
  
• Help track and record information, such as when and how to take medicines, which foods to avoid, and which forms of exercise are safe.
  
  
• Offer to make healthy changes together. If your loved has to stop smoking, start exercising or change diet, make the same changes yourself.
