Signs You Should See a Private Cardiologist (Even If You Feel Fine)

By Dr Nabila Laskar — published September 2026.

Not all cardiac symptoms are obvious. Here are the signs that warrant a cardiologist appointment, even when you feel otherwise well, from Dr Nabila Laskar.

Most people assume a cardiologist is only for people who have already had a heart attack. The reality is that the most valuable cardiac assessment happens before a cardiac event, not after. Here are the signs that should prompt you to book a consultation, even if you feel broadly well.

You get palpitations that come and go

Occasional ectopic beats are very common and usually harmless. But palpitations that are frequent, last longer than a few seconds, feel like a sudden racing heart, or are accompanied by dizziness or chest tightness need investigation. A 7-day Holter monitor captures rhythm over a full week and is far more likely to catch intermittent arrhythmias than a single clinic ECG.

You get breathless more easily than you used to

Progressive breathlessness on exertion is one of the most commonly dismissed cardiac symptoms. Patients frequently attribute it to being out of shape or getting older. An echocardiogram assesses heart function directly and will identify reduced pumping function, valve problems, or early heart failure that exercise tolerance alone cannot exclude.

A close family member had heart disease young

A first-degree relative (parent or sibling) who had a heart attack before 60, or who died suddenly of a presumed cardiac cause, puts you at significantly elevated risk. Familial hypercholesterolaemia and hypertrophic cardiomyopathy are both inherited conditions that can be identified and managed before they cause problems.

Your blood pressure is consistently above 140/90

Many people discover this on a pharmacy machine and then do nothing about it. Sustained hypertension silently damages blood vessel walls and the heart over years. A cardiologist-led assessment includes 24-hour ambulatory monitoring to confirm the diagnosis accurately, rather than relying on a single reading taken when you may be stressed.

You have been told you have a heart murmur

An incidental murmur found by your GP or during a routine medical warrants an echocardiogram to determine whether it is innocent or caused by valve disease. Most are innocent, but the only way to know for certain is to look.

You are over 40 and have never had a cardiac review

Cardiovascular risk accumulates silently across the fourth and fifth decade. Blood pressure, cholesterol, blood sugar, and family history combine to create a risk profile that either warrants intervention or provides genuine reassurance. A single comprehensive assessment in your early 40s is a rational investment.

You have been told to “watch and wait” for a cardiac symptom

Watching and waiting without a baseline echocardiogram or rhythm recording means there is nothing to compare against if things change. A baseline investigation now creates the reference point that makes future monitoring meaningful.

None of these require a GP referral at The Cardiology Doctors. If any of them apply, the appropriate next step is a consultant assessment, not more waiting.
