Advanced Heart Scans: Visualizing the Unseen

At A Healing Heart Medical, we move beyond simple blood tests. We utilize advanced diagnostic imaging to identify subclinical atherosclerosis—the arterial changes that happen years before a heart attack.

CT Coronary Angiogram (CTCA)

The CTCA is a non-invasive specialized scan that uses 3D reconstruction to visualize the coronary arteries. While standard health screenings often rely on a "Stress Test" (ECG), the CTCA is significantly more sensitive in detecting vulnerable soft plaque.

Clinical Insight

Many patients experience cardiac events despite having "normal" treadmill results. This is because standard tests only detect blockages exceeding 70%. The CTCA allows us to identify pre-obstructive plaque, giving us the opportunity to stabilize it before it ruptures.

Coronary Calcium Scoring

A Calcium Score is a low-dose, rapid CT scan that quantifies the amount of calcified plaque in your heart's arteries. It acts as a "Biological Age" marker for your vascular system.

Score 0: Zero Plaque 1-400: Moderate Risk >400: High Risk

This scan is essential for patients in their 40s or 50s who want a definitive risk assessment beyond their cholesterol numbers.

Echocardiography (Heart Ultrasound)

While CT scans look at the structure of the "pipes," the Echocardiogram looks at the function of the "pump." This non-invasive ultrasound allows us to see your heart valves and muscle in motion.

It is the primary tool used by Dr. Gerald Thang to diagnose Diastolic Dysfunction—a common condition in metabolic patients where the heart muscle becomes stiff and fails to relax properly.

Beyond Scans: Heart Rhythm & Electrical Monitoring

Beyond imaging the structure of your heart, we also assess its "wiring." Many patients with healthy-looking arteries may still experience electrical disturbances that affect their quality of life.
A heart can have perfect structure but "faulty wiring." We use electrical monitoring to investigate palpitations, dizzy spells, and the long-term impact of metabolic stress on heart rhythm.

12-Lead Resting ECG

Captures a snapshot of your heart's electrical activity to detect rhythm abnormalities (Arrhythmias) or signs of previous heart muscle injury.

24/48-Hour Holter Monitoring

A continuous recording used to catch intermittent symptoms, like "skipped beats", that often don't occur during a brief clinic visit.

Who is this for?

🔹 Palpitations or "Skipped" beats
🔹 Unexplained dizziness or fainting
🔹 Monitoring high blood pressure impact
🔹 Post-viral heart inflammation checks

Heart Scan: Patient Frequently Asked Questions

Passing a stress test means your heart gets enough blood during exercise. However, it doesn't show subclinical plaque. Most heart attacks are caused by the rupture of "soft" plaque that doesn't necessarily block blood flow. A CT Coronary Angiogram is the only non-invasive way to see this specific risk.

A Coronary Calcium Score is a low-dose CT protocol. The radiation exposure is roughly 1mSv, which is equivalent to about 6 months of "background radiation" you receive naturally from the environment. It is considered very safe for routine screening.

No. Because our scans are non-invasive (no catheters or sedation), there is zero downtime. You can drive yourself home, return to work, or even exercise immediately after an Echocardiogram or Calcium Score.

While the images are processed quickly, Dr. Gerald Thang personally reviews the raw data to correlate findings with your metabolic profile. We usually schedule a comprehensive review within 3–5 working days to discuss your Master Plan.
