When should you actually see a cardiologist?
Symptoms, risk factors and life stages that warrant a specialist visit — and what to expect at one.

Most chest twinges, palpitations, and bouts of breathlessness are not heart disease. But some are — and the cost of missing them is high. A cardiology referral is appropriate when the pattern of symptoms, your risk profile, or your baseline tests suggest the heart deserves a closer look.
Red-flag symptoms — go now, not later
- Crushing or pressure-like chest pain, especially with sweating, nausea, or pain radiating to the jaw or left arm.
- Sudden shortness of breath at rest.
- Fainting (syncope), particularly during exertion.
- A racing or irregular heartbeat that lasts more than a few minutes or recurs.
These warrant emergency care, not an outpatient referral.
Patterns worth a referral
- Exertional chest tightness that reliably appears at a predictable level of activity and resolves with rest.
- Progressive shortness of breath on stairs you used to manage easily.
- Persistent palpitations, especially if you have a family history of arrhythmia or sudden cardiac death.
- Newly elevated blood pressure that isn't responding to first-line treatment — see our primer on understanding your blood pressure numbers.
Risk-driven referrals (you may feel fine)
You may benefit from a cardiologist's input even without symptoms if you have:
- Strong family history of heart attack before age 55 (men) or 65 (women).
- Type 2 diabetes, especially with other risk factors — see our guide for the newly diagnosed.
- LDL cholesterol persistently above 4.9 mmol/L (190 mg/dL).
- A history of preeclampsia or gestational diabetes.
- Known coronary calcium on a prior CT scan.
What to expect at the first visit
A cardiologist will usually take a detailed history, examine you, and order an ECG and echocardiogram. Depending on findings, this may extend to a stress test, Holter monitor, or coronary CT angiography. Most workups are completed within two to three visits.
