Preventative Cardiology in London with Dr Ozan Demir.

Preventative Cardiology

Most heart attacks are not bolts from the blue — they are the end result of coronary disease developing silently for years, and in about half of cases, the first 'symptom' is the heart attack itself. However, cardiovascular disease is the most preventable of all serious illnesses. A heart health assessment through preventative cardiology asks three crucial questions: what is your individual risk, is there disease already present in your arteries, and what — specifically — should you do about it? 

 

As a cardiologist, I spend much of my week treating advanced heart disease in the catheter lab — which is exactly why I take prevention seriously. Almost every heart attack I treat was preventable at some point years earlier, emphasizing the importance of early intervention and regular cardiologist consultations.

Who should consider a preventative cardiac assessment?

You do not need symptoms to benefit from a heart health assessment. It is particularly worthwhile to seek a cardiologist consultation if you have: A family history of heart disease — especially if a parent or sibling was affected at a young age; one or more risk factors such as high blood pressure, raised cholesterol, diabetes or pre-diabetes, current or previous smoking, or excess weight; a high-pressure lifestyle involving long hours, stress, poor sleep, and little time for exercise; reached your 40s or 50s without ever having your heart properly assessed — which is a common and entirely reasonable reason to seek an evaluation; or a borderline result elsewhere like a raised cholesterol reading, a blood pressure reading that should be monitored, or a health-screen finding that requires proper interpretation.

What does a preventative assessment involve?

This is not a tick-box screening package; it is a consultant-led heart health assessment designed around you, divided into three essential parts: 


1. Understanding your risk: A detailed cardiologist consultation covering your personal and family history, lifestyle, and complete risk factor profile, along with a physical examination and baseline checks in the clinic. This discussion forms the foundation of everything that follows—your risk cannot be understood from test results alone. 


2. Investigations tailored to you: There is no fixed menu of tests because the right investigations depend entirely on your history and risk profile. After your consultation, I will outline which tests are appropriate for you and the rationale behind them—potentially including blood testing, heart rhythm and blood pressure assessment, imaging of the heart, or scans of the heart's arteries. Equally important, I will indicate which tests you don’t need: more testing is not better testing, and every investigation I recommend will have a clear purpose in addressing your specific questions. 


3. A specific, personal plan: You will leave with a clear understanding of your actual risk and a written plan that includes specific targets, treatments where the evidence supports it (and explicitly not where it doesn’t), lifestyle priorities ranked by impact, and a sensible follow-up schedule. Prevention only works if the plan is one you can realistically adhere to.

What can be prevented?

The evidence for prevention is among the strongest in medicine: 


Managing cholesterol reliably reduces heart attack and stroke risk — and the earlier it is addressed, the greater the benefit. Additionally, a thorough heart health assessment can identify these issues sooner. Treating high blood pressure protects against heart attack, stroke, heart failure, and kidney disease. Detecting silent heart disease early allows treatment that halts progression — years before symptoms would ever appear. Identifying inherited risk changes management for you and, often, your relatives. Lifestyle change, when properly targeted, remains the foundation: activity, weight, diet, sleep, and stopping smoking each carry measurable, compounding benefits.


Prevention is not about medicalizing healthy people. Many patients leave a cardiologist consultation reassured — with medication safely deferred — while others discover risks worth treating early. Both outcomes are positive; what truly matters is that the decision rests on evidence tailored to your unique situation.

Why choose Dr Ozan Demir for preventative cardiology?

The interventionalist's perspective — I treat the end results of heart disease every week and bring that experience to preventing them; I know exactly what we are trying to avoid. For a comprehensive heart health assessment, I provide tailored, evidence-based evaluations specifically chosen for your individual history and risk profile, ensuring it’s not a one-size-fits-all package. You can expect honest advice in both directions — treatment is recommended where evidence supports it, and deferred with confidence where it doesn't. With a PhD from King's College London and over 100 peer-reviewed publications, I emphasize rapid access, offering same-week cardiologist consultations at Heart Health Welbeck London (Marylebone), Cromwell Hospital (Kensington), The Wellington Hospital (St John's Wood), Bupa Health Care Canary Wharf, and The Essex Cardiothoracic Centre (Basildon). Consultations are available in both English and Turkish, and I am recognized by all major private medical insurers; self-paying patients are always welcome.

Book an assessment

The best time to assess your heart health is before it ever gives you a reason to seek help. Contact my practice team to arrange a cardiologist consultation for a preventative heart health assessment at one of my London or Essex locations.
