Heart failure is a weakening of the heart that can develop over a long period of time. It doesn't mean your heart has stopped or is about to stop.
Your heart pumps oxygen and nutrient-rich blood through your body helping you carry out the normal activities of daily living. When it begins to fail that means your heart can't pump enough blood to meet your body's needs and your muscles weaken and begin to waste away, causing fatigue or tiredness.
Signs and symptoms may include: shortness of breath; cough; fatigue; sudden weight gain of two to three pounds in one day, or five pounds in a week; increased heart rate and increased thirst.
Ask your doctor or call (888) 741-5115 to learn more about heart failure.
