Cardiac Edema

Edema is the medical term for swelling. Edema happens when your small blood vessels (arteries and veins) leak fluid into nearby tissues. Doing so creates an excess amount of fluid. As the fluid builds up, the nearby tissues respond by swelling. Cardiac edema occurs when the heart’s diseased or overworked left ventricle (heart’s lower chamber) isn't able to pump out enough of the blood it receives from your lungs. This causes the heart to hold an excess amount of fluid; therefore, swelling.

Lifestyle changes and medications can help control cardiac edema, which can affect your quality of life. If you have cardiac edema or are concerned that you might, make an appointment to talk to a cardiologist.
