What does a cardiologist do?

A cardiologist diagnoses and treats diseases of the heart and blood vessels — coronary artery disease, heart failure, arrhythmias, high blood pressure, valve problems, and more. Some cardiologists sub-specialize (interventional, electrophysiology, structural heart) and work alongside surgeons, primary-care physicians, and other specialists.

Most patients see a cardiologist after a referral from their primary-care provider, but you can self-refer if your insurance allows it. Common reasons people seek a cardiologist directly: a family history of early heart disease, persistent chest discomfort, palpitations, or a recent abnormal EKG or stress test.

How to choose the right cardiologist

When you're choosing a cardiologist, three things make the biggest practical difference: (1) the cardiologist's sub-specialty matches your concern, (2) they're in-network with your insurance, and (3) they're actually accepting new patients. ProviderQuoHealth surfaces all three on every profile so you can rule out mismatches before you pick up the phone.

If you need urgent care for chest pain or symptoms of a heart attack, call 911 or go to the nearest emergency department — don't search a directory.

FAQ

Frequently asked

Do I need a referral to see a cardiologist?

Most insurance plans accept self-referral to a cardiologist, but some HMOs require a referral from your primary-care provider first. Check the cardiologist's profile for accepted insurance, or call your insurer to confirm before booking.

How is a cardiologist different from a heart surgeon?

Cardiologists manage heart conditions medically — diagnosis, medication, lifestyle planning, and minimally-invasive procedures like cardiac catheterization. Cardiothoracic surgeons perform open-heart and major vascular surgery. The two work together; the cardiologist usually manages your ongoing care.

What should I bring to my first appointment?

Bring a list of every medication and supplement you take (with dosages), recent EKGs / lab results / imaging if you have them, and a written history of cardiac symptoms (when they happen, how long, what makes them better or worse). A family history of heart disease is also useful.
