Why “Heart Health Check-up” is More Important Than You Think
Heart disease remains one of the leading causes of death among Thai people and is often called the “silent killer” because it frequently shows no warning signs in advance. Heart health check-ups are therefore an important tool that helps to
- Assess the risk of heart disease
- Detect abnormalities from the early stages
- Plan prevention before severe disease occurs
Doctors will select tests based on age, risk, and individual symptoms.
What Does a Heart Health Check-up Include?
1. Electrocardiogram (Electrocardiogram : ECG / EKG)
A basic screening test
- Checks the electrical activity of the heart
- Takes only 5–10 minutes
- Painless and no preparation needed
Helps detect
- Irregular heartbeats
- Ischemic heart muscle conditions
- Enlarged heart
2. Echocardiogram (Echocardiogram : Echo)
Uses sound waves to view the heart’s structure in real-time
- Shows heart contractions
- Examines heart valves and chambers
Helps detect
- Enlarged heart
- Leaky or narrowed heart valves
- Abnormal heart function
3. Cardiac Stress Test (Stress Test / Exercise Test)
Tests heart function “under exertion” to assess ischemia
- Treadmill walking or medication alternative
- Measures pulse, blood pressure, and ECG during exertion
Helps detect
- Coronary artery narrowing
- Ischemia during exertion
- Heart performance
4. Blood Test (Blood Test)
Helps screen risk factors before heart disease develops. Although not a direct heart test, it is “very important” for risk assessment such as
- Blood lipids (LDL, HDL, Cholesterol)
- Blood sugar (diabetes risk)
- Cardiac biomarkers
5. 24-Hour Heart Rhythm Monitor (Holter Monitor)
- Wear the device for 24–48 hours
- Continuously records heartbeats
Suitable for
- Those experiencing palpitations or dizziness
- Detecting abnormalities not found in a normal ECG
6. Cardiac CT Scan (CT Scan / CT Coronary)
An advanced test to view coronary arteries
- Detects calcified plaques
- Assesses heart disease risk
Helps detect
- Coronary artery narrowing
- Calcification in blood vessels
7. Coronary Angiogram (Coronary Angiogram)
The most in-depth and accurate test
- Catheter inserted through arm or leg to view blood vessels
- Clearly shows location of narrowing/blockage
Used in cases of
- Suspected severe coronary artery disease
- Preparing for further treatment such as balloon angioplasty or stent placement
Which Heart Test is Suitable for Whom?
Young adults aged 20–35 years
- Basic health check-up
- ECG (if symptoms or risk of heart abnormalities)
Adults aged 35–50 years
- Lipid and blood sugar tests
- ECG
- Stress Test (for some with mild fatigue or chest pain)
Adults over 50 years / High-risk groups
- Echo
- Stress Test
- CT Scan or Calcium Score
Warning Signs That Require Immediate Heart Check-up
If you have any of these symptoms, do not wait
-
- Chest pain or tightness
- Unusual shortness of breath
- Palpitations or irregular heartbeat
- Dizziness or fainting
How Often Should You Have a Heart Health Check-up?
- Healthy individuals should check every 1–2 years
- High-risk individuals should check annually or more often as advised by a doctor
Frequently Asked Questions (FAQ)
Q: Do I need to fast before a heart test?
A: It depends on the test. For example, blood tests require fasting, but ECG does not.
Q: Does a heart test hurt?
A: Most tests do not cause pain, such as ECG, Echo, and Stress Test.
Q: At what age should I start heart check-ups?
A: Starting from age 20, especially if you have risk factors.
Heart health check-ups are not just one type of test but involve evaluating the heart’s health from multiple dimensions, including structure, function, and risk of coronary artery disease.
This helps detect abnormalities early before severe conditions develop. Doctors will choose appropriate tests based on age, symptoms, and risk factors because many heart diseases may not show clear symptoms initially.
Regular and appropriate testing is an important way to care for your heart and confidently plan your long-term health.
