Cardiology is the area of medicine focused on the heart and blood vessels. A cardiologist helps evaluate symptoms, diagnose heart and vascular conditions, reduce future risk, and guide treatment when a heart problem is found.
You may see a cardiologist for a new symptom, a known condition, an abnormal test result, or a second opinion about your heart health. Some visits are urgent, while others are about prevention and long-term planning.
What cardiologists help with
- Chest pain, pressure, or discomfort
- Shortness of breath with activity or at rest
- Palpitations, skipped beats, or a racing heartbeat
- Fainting, near-fainting, or unexplained dizziness
- High blood pressure, high cholesterol, or cardiovascular risk
- Heart failure, heart valve disease, and irregular heart rhythms
- Abnormal ECG, echocardiogram, stress test, CT, or other heart test results
When to consider seeing a cardiologist
It may be worth asking about cardiology care if you have symptoms that could be heart-related, especially if they are new, worsening, or happening with exertion. It is also reasonable to seek evaluation if you have risk factors such as high blood pressure, diabetes, smoking history, kidney disease, high cholesterol, or a strong family history of early heart disease.
What to expect at a first cardiology visit
A first visit usually starts with your symptoms, medical history, medications, family history, and risk factors. The clinician may check your blood pressure, listen to your heart and lungs, review past records, and decide whether tests are needed.
Common tests may include an ECG, blood tests, echocardiogram, stress test, heart rhythm monitor, cardiac CT, cardiac MRI, or other imaging depending on the question being asked.
When symptoms may be urgent
Some symptoms should not wait for a routine appointment. Call emergency services right away if you have warning signs of a heart attack, such as chest discomfort, discomfort spreading to the arm, back, neck, jaw, or stomach, shortness of breath, cold sweat, nausea, or lightheadedness.
