Heart failure is a condition in which the heart muscle is unable to pump enough blood to meet the bodys needs for blood and oxygen. The heart is a strong, muscular pump that delivers oxygen- and nutrient-rich blood to the bodys cells. With heart failure, the weakened heart cant supply the cells with enough blood, which results in fatigue and shortness of breath. Everyday activities such as walking, climbing stairs, or carrying groceries can become very difficult.

Heart failure is a serious condition, and usually, theres no cure. However, many people with heart failure lead a full, enjoyable life when the condition is managed with heart failure medications and a healthy lifestyle. Its also helpful to have the support of family and friends who understand the condition.

The most common cause of heart failure is coronary artery disease, which is the narrowing of the blood vessels that supply blood and oxygen to the heart. Other heart problems that may cause heart failure include heart attack, heart valves that are leaky or narrowed, infection that weakens the heart muscle, and some types of abnormal heart rhythms. Other diseases that can cause or contribute to heart failure include amyloidosis, emphysema, and overactive thyroid.

Symptoms of heart failure may include feeling short of breath, fatigue or weakness even after rest, coughing, and swelling and weight gain from fluid in your ankles. If you experience any of these symptoms, its important to seek medical attention right away.
