What is an enlarged heart?

Did you know that your heart pumps about 1.5 million gallons of blood during your lifetime? That’s a lot of work for an organ that is no larger than your fist.

We recently received this question from a viewer:

Q: My dad's doctor told him that he has an enlarged heart at his last appointment. What does that mean?

The answer: It’s known as cardiomegaly, and it’s often a sign of an underlying problem.

“An enlarged heart is a general term that refers to the pumping chamber of your heart,” said Dr. Nieca Goldberg, medical director of the Joan H. Tisch Center for Women’s Health. “There are several conditions that can cause an enlarged heart and those include untreated high blood pressure, diabetes and obesity.”

Some people with an enlarged heart will not have any symptoms. But others may experience:

- Shortness of breath

- Dizziness

- Irregular heart beat

- Swelling

- Cough

- Chest pain

Symptoms involving the heart should always be taken seriously, so if you have any, you should call your doctor immediately. The best way to find out if you have an enlarged heart is by getting an echocardiogram or an ultrasound.
