Heart Health: How to Detect Problems Before Symptoms Appear
By Dr Lauren Holland | Marylebone Diagnostic Centre, London
Heart disease remains the leading cause of death in the UK – yet most people never realise their risk until they experience symptoms.
The good news? Many heart problems can be detected early through simple blood and cardiovascular tests long before you feel unwell.
At Marylebone Diagnostic Centre (MDC), we specialise in preventive testing that gives you a complete view of your cardiovascular health – fast, private, and with QC-validated accuracy.
Why Early Heart Testing Matters
Your heart works continuously, beating around 100,000 times a day.
Even minor imbalances in cholesterol, blood sugar, or inflammation can quietly damage arteries over time.
Early testing can detect these warning signs before they lead to:
- Heart attack
- Stroke
- Angina (chest pain)
- High blood pressure complications
- Circulatory problems
When identified early, most risks can be controlled or reversed with lifestyle changes and, if necessary, medication.
The Hidden Signs of a Struggling Heart
Heart disease can progress silently. Some of the subtle symptoms people ignore include:
- Unexplained fatigue or shortness of breath
- Chest discomfort or tightness
- Dizziness or fainting spells
- Cold hands and feet
- Swelling in ankles or legs
- Erectile dysfunction (in men)
If you have any of these symptoms – or a family history of heart disease – it’s time for a heart health check.
The Key Heart Tests Available at MDC
At Marylebone Diagnostic Centre, our Comprehensive Heart & Cholesterol Profile assesses the major markers of cardiovascular health:
1. Lipid Profile
Measures total cholesterol, LDL, HDL, and triglycerides to assess artery health.
2. hs-CRP (High Sensitivity C-Reactive Protein)
Detects low-grade inflammation linked to arterial damage and heart attack risk.
3. HbA1c (Average Blood Sugar)
High levels can damage blood vessels, increasing heart and stroke risk.
4. Kidney & Liver Function Tests
Kidney disease and liver imbalance are closely linked to high blood pressure and metabolism.
5. Thyroid Function (TSH, FT4)
Thyroid imbalance affects heart rhythm, cholesterol, and blood pressure.
All testing is performed under our QC-validated protocols, ensuring every result meets the Marylebone High Standard.
Who Should Have a Heart Screening?
You should consider testing if you:
- Are over 40 or have a family history of heart disease
- Smoke or drink regularly
- Have high blood pressure or diabetes
- Live a sedentary lifestyle
- Experience fatigue or stress-related symptoms
Preventive testing is particularly valuable for professionals managing long hours and stress – common in London’s fast-paced environment.
