Heart Failure

Heart failure, also known as congestive heart failure, occurs when the heart muscle becomes too weak or stiff to pump blood effectively. This reduced pumping ability means the body’s organs and tissues do not receive enough oxygen and nutrients, leading to symptoms such as fatigue, shortness of breath, swelling in the legs, and difficulty performing daily activities.

The condition can affect either the left or right side of the heart, or both. Left-sided heart failure often causes fluid buildup in the lungs, while right-sided failure leads to swelling in the abdomen, legs, and feet. Common causes include coronary artery disease, high blood pressure, heart valve problems, and previous heart attacks.

Although heart failure is a serious, lifelong condition, it does not mean the heart has stopped working. With proper treatment—such as medications to reduce fluid retention, devices to support heart function, and lifestyle changes like reducing salt intake, exercising moderately, and managing stress—many people live fulfilling lives.
