In brief: If

If you are experiencing shortness of breath and difficulty breathing when laying down, these are signs of congestive heart failure, and more specifically left heart failure.
In left heart failure, fluid builds up in the lungs causing shortness of breath and difficulty breathing when laying down. Fatigue is also a sign that your heart may be working too hard. See a doctor sooner than your appointment. Go to the emergency room to be assessed if you can not get in right away to see your cardiologist.
