When to See a Cardiologist
Signs you should see a heart specialist instead of (or in addition to) your primary care doctor.
What a cardiologist does
Cardiologists diagnose and treat diseases of the heart and blood vessels — coronary artery disease, heart failure, arrhythmias, valve disease, and hypertension that's hard to control. Most cardiologists work closely with your primary care doctor rather than replacing them.
See a cardiologist if you have
- Chest pain, pressure, or shortness of breath with activity
- High blood pressure not controlled by 2+ medications
- Heart palpitations or fainting episodes
- Family history of heart disease before age 55 (men) or 65 (women)
- High cholesterol despite treatment
- A heart murmur, abnormal EKG, or known valve issue
- Diabetes plus cardiovascular risk factors
When to call 911 instead
Crushing chest pain, pain radiating to the arm or jaw, sudden severe shortness of breath, fainting, or stroke symptoms (face droop, arm weakness, speech difficulty) — call 911 immediately. Don't drive yourself.
What to expect at the visit
A first cardiology visit usually includes a detailed history, physical exam, EKG, and often an echocardiogram or stress test. Bring your medication list, recent labs, and any prior cardiac testing.
