heart failure

Heart failure occurs when the heart cannot pump enough blood to meet the body’s needs.[52] Heart failure appears as a chronic condition, associated with age, and increases gradually.[55] One side of the heart can fail but not the other, resulting in either right or left heart failure. Left heart failure can lead to right heart failure by increasing pressure on the right heart. If the heart becomes unable to pump blood adequately, blood can accumulate throughout the body, leading to shortness of breath in the lungs (pulmonary congestion, pulmonary edema), swelling (edema) of the feet or other areas depending on the effect of gravity, and decreased Endurance in exercise, or may cause other clinical signs such as hepatomegaly, heart murmurs, or elevation in jugular vein pressure. Common causes of heart failure include coronary artery disease, valve disorders, and heart muscle disease.[56]
