One of the earliest symptoms of heart failure is shortness of breath. Your heart can't function well enough to pump the blood out of your heart, and this causes blood to back up in the blood vessels leading to the lungs. Fluid then leaks from your blood vessels into the air sacs in your lungs. This makes it difficult for oxygen to enter the blood, causing shortness of breath.
You may experience breathlessness during exertion, such as when carrying groceries, climbing a flight of stairs, or at rest--even at night when sleeping.
