Heart failure does not actually mean your heart is failing or about to stop working. It means your heart muscle has weakened over time and cannot receive or pump blood as well as it used to. This can lead to congestion or a backup of blood in the heart. As a result, not enough oxygen-rich blood will be pumped to your body’s other organs. Heart failure can be acute, occurring suddenly, or it can be chronic and ongoing. The symptoms of heart failure can include:  Shortness of breath when you do physical activity (dyspnea) or when you lie down (orthopnea) Fatigue and weakness. A rapid or irregular heartbeat. Swelling (edema) in your legs, ankles, and feet. Your abdominal area may also swell due to fluid build-up (ascites).  Reduced ability or inability to exercise. Persistent coughing or wheezing with white or pink blood-tinged phlegm. Increased need to urinate at night. Sudden weight gain due to fluid retention. Lack of appetite and nausea. Difficulty concentrating and decreased alertness. Chest pain. Heart failure is often the result of other heart problems or issues that become worse or that weaken your heart. You can experience heart failure on the left side or ventricle, on the right side or right ventricle, or both sides of your heart at once. In general, heart failure starts on the left side of your heart, which is your heart’s main pumping chamber. Heart conditions that can lead to heart failure include:  Coronary artery disease: This is the most common form of heart disease and the most common cause of heart failure. If you have this disease, your arteries begin to narrow due to a buildup of fatty deposits, causing a reduction of blood flow to your heart. This disease can lead to a heart attack, as the buildup of fatty deposits can cause a blood clot to form and block blood flow to your heart. High blood pressure or hypertension: Blood pressure is amount of force of blood that is pumped to your heart by your arteries. If you have high blood pressure, this means your heart has to work harder than normal...
