Congestive Heart Failure Basics

Heart failure happens when your heart muscle isn't pumping enough blood to the rest of your body. Because the heart isn't pumping as it should, fluids can start to build up. This build-up of fluid is called congestion. This is why we call the condition congestive heart failure.

In addition, your body might do other things to make up for the weakened pumping of your heart. You might hold salt and water in the blood, increasing the amount of blood in your system. Your heart might also beat faster or get larger.

We can treat congestive heart failure to slow the disease and help you feel better and live longer.

Risk Factors

The main risk factors for congestive heart failure are:

Symptoms to Watch For

Weakness, feeling tired. When your heart isn't pumping effectively, the body doesn't get enough oxygen-rich blood to meet your energy demands.

Shortness of breath, coughing. When fluid builds up in your lungs, you may find it hard to catch your breath or may have a frequent cough. You may also have shortness of breath when lying down.

Weight gain. Sudden or steady gain in daily weight (for example, 2 to 3 pounds in 24 hours or 5 pounds or more in 1 week) shows that the body is retaining fluid.

Swelling of feet or ankles. When the body retains fluid, you might have swelling in your feet and ankles.

Changes in the frequency of urination. When the heart isn't pumping effectively, the kidneys can't remove excess fluid from the body. You might urinate less frequently during the day or more frequently at night.
