Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.
Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing sodium in your diet, managing stress and losing weight — can improve your quality of life.
One way to prevent heart failure is to prevent and control conditions that cause heart failure, such as coronary artery disease, high blood pressure, diabetes or obesity.
See your doctor if you think you might be experiencing signs or symptoms of heart failure. Seek emergency treatment if you experience any of the following:
Chest pain Fainting or severe weakness Rapid or irregular heartbeat associated with shortness of breath, chest pain or fainting Sudden, severe shortness of breath and coughing up pink, foamy mucus
Although these signs and symptoms may be due to heart failure, there are many other possible causes, including other life-threatening heart and lung conditions. Don't try to diagnose yourself. Call 911 or your local emergency number for immediate help. Emergency room doctors will try to stabilize your condition and determine if your symptoms are due to heart failure or something else.
