Heart failure affects more than five million Americans. Heart failure occurs when the heart can no longer pump blood efficiently to the body’s other organs, resulting in those organs failing as well. This can lead to the development of some or all of the following symptoms: fatigue, swelling in the feet, ankles, or abdomen, shortness of breath, and/or cough. Those at risk include diabetic patients, patients with high blood pressure, and patients with a history of heart attack.
