Cardiac CT & Coronary Calcium Score Bangkok — Prices & Guide (2026)

WhatsApp𝕏 Tweet
Coronary artery disease (CAD) causes heart attacks — and most people have no symptoms until a major cardiac event occurs. A coronary artery calcium (CAC) score CT scan is a simple 10-minute test that measures calcified plaque in the coronary arteries and accurately predicts heart attack risk 10–15 years in advance. In the USA and Europe, a CAC score costs $400–$1,500 and CT coronary angiography $2,000–$6,000. In Bangkok, the same tests cost ฿4,000–฿8,000 (CAC) and ฿15,000–฿35,000 (CTCA) — 60–80% less — with same-day results at JCI-accredited hospitals. This guide explains who should get a cardiac CT in Bangkok and what to expect.

Cardiac CT prices in Bangkok (2026)

Coronary artery calcium score and CT coronary angiography prices at Bangkok private hospitals:

  • Coronary artery calcium (CAC) score CT scan: ฿4,000–฿8,000 — the 10-minute calcium scoring scan; no contrast needed; quick, very low radiation dose
  • Bumrungrad International: CAC score approximately ฿5,000–฿7,000
  • Samitivej Sukhumvit: approximately ฿4,500–฿6,500
  • Bangkok Hospital: approximately ฿4,000–฿6,000
  • CT coronary angiography (CTCA — 64-slice or higher): ฿15,000–฿35,000 — detailed imaging of the coronary arteries with contrast dye; requires IV cannula; 20–30 minute procedure
  • CTCA at Bumrungrad: approximately ฿20,000–฿35,000 (dual-source CT, high accuracy for rapid heart rates)
  • CTCA at Samitivej: approximately ฿18,000–฿30,000
  • Cardiac CT angiography for structural heart disease (not coronary): ฿20,000–฿40,000
  • US/UK price comparison: CAC score $300–$1,500; CTCA $2,000–$6,000 — Bangkok typically 60–80% cheaper
  • Preparation: no caffeine 12 hours before CTCA; no fasting needed for CAC score; beta-blocker may be given to slow heart rate before CTCA (pre-medicated at hospital)

Coronary calcium score — what it means

Understanding your Agatston CAC score from a Bangkok cardiac CT:

  • CAC score = 0: no calcified plaque detected — very low 10-year risk of major cardiac event (<1%); most JCI guidelines recommend no statin if score is 0 and no other risk factors
  • CAC score 1–99: mild calcification — low-to-moderate risk; statin may be recommended depending on other risk factors (age, LDL, diabetes, hypertension); follow-up in 5 years
  • CAC score 100–399: moderate calcification — moderate risk; statin therapy generally indicated; lifestyle intervention essential
  • CAC score 400–999: high calcification — high risk for cardiac event in next 10 years; intensive statin therapy + aspirin usually recommended; consider CTCA for stenosis severity
  • CAC score ≥1000: very high calcification — very high risk; aggressive medical management; cardiology follow-up essential
  • CAC score is age- and sex-adjusted: a score of 100 means different risk levels at age 45 vs 65 — your Bangkok cardiologist will interpret in context
  • Zero CAC score is powerful: a zero score in an asymptomatic person reclassifies them to lower risk and can often defer statin therapy — a 'heart attack warranty' for approximately 5 years
  • CTCA vs CAC score: CAC score detects calcified plaque (burden); CTCA shows stenosis (blockage severity); CTCA is needed if CAC is high or symptoms are present

Who should get a cardiac CT in Bangkok, and when

Indications for cardiac CT at a Bangkok health check-up:

  • Intermediate cardiovascular risk (10-year ASCVD risk 7.5–20%): CAC score is most useful in this group to guide statin decision; recommended by ACC/AHA 2019 guidelines
  • Age 40–75 with any cardiovascular risk factor (hypertension, diabetes, smoking, family history, dyslipidaemia): consider CAC score to quantify subclinical atherosclerosis
  • Already on statin but uncertain about cardiovascular benefit: CAC score = 0 may support de-escalation discussion with your cardiologist
  • Check-up found: elevated LDL cholesterol, borderline high blood pressure, or HbA1c in prediabetes range — CAC score adds risk quantification beyond labs alone
  • Strong family history of premature heart disease (first-degree relative with MI or cardiac death before age 55 men / 65 women): CAC score from age 40
  • Symptomatic patients (chest pain, exertional dyspnoea): CTCA instead of CAC score — to assess stenosis
  • Bangkok cardiologist consultation (฿2,000–฿4,000): needed to interpret results and decide management — always get a specialist to review results; never use CAC score alone without clinical context
  • No symptoms, low risk (young, no risk factors): CAC score not recommended — radiation exposure (1–3 mSv, equivalent to 6 months background radiation) outweighs benefit in very low-risk patients

Frequently Asked Questions

Can I get a coronary calcium score in Bangkok without a doctor referral?

Yes — most Bangkok private hospitals allow direct booking for a CAC score CT scan without a referral letter. However, a cardiologist consultation (฿2,000–฿4,000) before or after the scan is strongly recommended to: interpret your specific score in context of your age, sex, and other risk factors; decide whether to start or adjust statin therapy; and determine if further testing (CTCA, stress test) is needed. Booking: call Bumrungrad (+66 2 011 3000), Samitivej (+66 2 022 2222), or Bangkok Hospital (+66 2 310 3000) international patient services and ask for a 'cardiac CT' or 'calcium scoring' appointment. Some hospitals require cardiology consultation first.

Is CT coronary angiography (CTCA) safe? How much radiation?

CTCA exposes you to approximately 2–5 mSv of radiation — equivalent to 1–2.5 years of natural background radiation, or 100 chest X-rays. This is lower than conventional invasive coronary angiography and much lower than a nuclear stress test. CAC score CT is even lower — approximately 1–2 mSv. Modern CT scanners at Bangkok JCI hospitals (dual-source, high-pitch helical acquisition) use dose modulation to minimize radiation. The radiation risk for a 50-year-old getting a single CTCA is very small and generally outweighed by the diagnostic information for appropriate patients. Contrast reaction is the main procedural risk: 1 in 2,000 reactions with modern iso-osmolar contrast; the hospital will screen you for allergy and kidney disease before injecting.

My Bangkok check-up found a high LDL or borderline cardiac risk — should I get a cardiac CT?

A CAC score is a useful next step when your 10-year cardiovascular risk is intermediate (7.5–20%) and the statin-vs-no-statin decision is uncertain. If your Bangkok check-up shows: LDL 130–190 mg/dL without other major risk factors, OR borderline blood pressure (130–139/80–89), OR prediabetes HbA1c (5.7–6.4%), OR age 40–75 with 1 risk factor — a CAC score can tip the decision. If CAC = 0, many cardiologists would recommend lifestyle changes without statin for 5 years. If CAC ≥100, statin therapy is generally recommended. Book a cardiologist consultation (฿2,000–฿4,000) alongside the scan — available same-day at Bumrungrad and Samitivej.
