Heart disease is the number one killer in Singapore. It accounts for around three in every ten deaths, and on an average day about 34 people here have a heart attack. The hard truth behind those numbers is that coronary artery disease (the furring-up of the heart’s own blood vessels) builds silently for years before it ever causes a symptom. Many people first discover they have a problem when they have a heart attack. The whole point of a heart screening is to find the warning signs long before that day comes, while there is still time to act.
In this article I will walk you through what a thorough cardiac screen actually involves, what each test is looking for, and, just as importantly, why not everyone needs every test. The best heart screening package in Singapore is not the longest one; it is the one matched to your personal risk.
What is a heart screening?
A heart screening is a structured check for the conditions that lead to heart attacks and strokes, done before they cause trouble. Think of it as a service for the heart: we look for the things that quietly raise your risk, such as high blood pressure, high cholesterol, diabetes, and early plaque in the arteries, and for problems with the heart’s structure or rhythm that you might not feel yet.
Crucially, screening is for people who feel well. If you already have symptoms such as chest tightness on exertion, breathlessness, palpitations, or blackouts, that is not screening, that is assessment of a problem, and it should be dealt with more urgently. (If you are getting chest pain, please read my guide on the different types of chest pain, and if it is severe or comes with sweating or breathlessness, call 995 now.)
Who should get a heart screening?
The simple principle I work to is this: the higher your risk, the more thorough the screening should be. A fit 30-year-old with no family history needs very little. A 55-year-old smoker with diabetes and a father who had a heart attack at 50 needs a great deal more.
The things that push your risk up, and therefore lower the age at which I would suggest screening, are:
- Age. Risk climbs steadily with age. As a rough guide, I would think about a baseline screen from around your 40s, earlier if other risk factors are present.
- Family history. A close relative who had a heart attack or stroke young (men under 55, women under 65) is one of the strongest signals, because some risk is inherited.
- The “three highs.” High blood pressure, high cholesterol, and diabetes. Around one in five Singaporeans has at least one of these, and they often run together.
- Smoking, being overweight, an inactive lifestyle, and high stress.
- Sex. Men tend to develop coronary disease earlier than women, though heart disease remains the leading killer of both.
One Singapore-specific point worth knowing: South Asians and several other groups in our region develop coronary artery disease earlier and at lower body weights than Western populations. A meaningful share of heart attacks here happen in people under 65. That is a good reason not to assume you are “too young” to be checked.
What’s included in a comprehensive heart screen?
Here is what a genuinely comprehensive package can contain, and what each part is actually for. A basic package might be only the first three; a full work-up adds the imaging.
1. History and risk-factor review
The most valuable test is the conversation. Your symptoms, family history, lifestyle, and existing conditions tell me more about your risk than almost anything else, and they decide which of the tests below you actually need. A good screen starts here, not with a scanner.
2. Blood pressure and physical examination
High blood pressure is common, silent, and one of the biggest drivers of heart attacks, strokes, and heart failure, and it is very treatable once found. A proper reading (sometimes repeated, or with a 24-hour monitor) plus a focused examination is non-negotiable in any screen.
3. Blood tests
At a minimum, blood tests check cholesterol and blood glucose (HbA1c), the two big modifiable risk factors. A more thorough panel adds:
- ApoB (apolipoprotein B): a direct count of the harmful, artery-clogging cholesterol particles. I rate it as a more accurate measure of risk than standard LDL cholesterol alone, because it counts the particles rather than estimating the cholesterol inside them. I have written a full explainer on what apolipoprotein B is and why it matters.
- Lp(a), lipoprotein(a): a largely inherited form of cholesterol that raises risk independently of everything else. Major guidelines now recommend measuring it at least once in your lifetime, because the level is set by your genes and stays fairly stable, so a single test usually answers the question.
- Kidney and thyroid function, which both affect the heart and influence treatment.
4. ECG (electrocardiogram)
A quick, painless recording of the heart’s electrical activity. It can pick up rhythm problems such as atrial fibrillation, evidence of strain or thickened heart muscle, and signs of past damage. See my guide on what to expect during an ECG test.
5. Echocardiogram
An ultrasound scan of the heart that shows its structure and pumping in real time. It is how we detect valve disease, an enlarged or weakened heart muscle, and problems with how well the heart squeezes and relaxes, things an ECG and blood tests cannot see. Here is how to prepare for an echocardiogram.
6. Treadmill / exercise stress test
This checks how the heart copes under the demand of exercise. By recording the ECG (and your blood pressure and symptoms) while you walk on a treadmill, we can flag a heart that is not getting enough blood when it is working hard, a clue to significant coronary narrowing. More on what a cardiac stress test involves.
7. CT coronary calcium score
A quick CT scan, with no injection needed, that measures calcified plaque in the heart’s arteries and gives you a single number. A score of zero is strongly reassuring; a high score tells us plaque is already present and that risk-lowering treatment is warranted. It is one of the most useful tools we have for refining risk in people who fall in the middle, neither clearly low nor clearly high. See my guide to the CT calcium score.
8. CT coronary angiogram (CTCA)
A more detailed CT scan, using a contrast dye, that produces a clear picture of the coronary arteries themselves and shows actual narrowings and the makeup of the plaque. It is the most powerful non-invasive test for coronary disease, which is why it is usually reserved for people with symptoms or higher-risk findings, not used as a blanket first test for someone who feels completely well.
9. Carotid ultrasound and CIMT
Some packages also include an ultrasound scan of the carotid arteries, the vessels in the neck that supply the brain. It is quick, painless, and involves no radiation. We look for two things: visible plaque, which tells me atherosclerosis is already established, and the carotid intima-media thickness (CIMT), a measurement of the thickness of the artery’s inner lining. Because the same disease process affects arteries throughout the body, a thickened lining or plaque in the neck raises your overall cardiovascular risk, including the risk of stroke as well as heart attack, and often changes how aggressively we treat your risk factors.
How do I choose the right heart screening package?
This is where I would gently push back on the idea that “more is better.” Doing every test on a healthy 35-year-old is not thorough medicine. It is overtesting, and it can throw up incidental findings that lead to worry and yet more scans for no benefit. A risk-stratified approach is better for you and better medicine:
- Low risk (young, no risk factors, no family history): blood pressure, a lipid panel including ApoB, glucose, a once-in-a-lifetime Lp(a), and an ECG. Often that is plenty.
- Intermediate risk (some risk factors, or a strong family history): the above plus a CT calcium score or angiogram to clarify whether plaque is already there, and frequently an echocardiogram.
- Higher risk (multiple risk factors, diabetes, or any symptoms): a fuller work-up that may include a stress test and a CT coronary angiogram, plus close attention to treating the risk factors we find.
The honest answer is that the right package is decided with a cardiologist, not picked off a menu. The tests should follow your risk, not the other way round.
As a guide, heart screening packages in Singapore typically range from around $450 for a basic screen up to about $3,500 for a comprehensive package with advanced imaging. The exact figure depends on which tests are included, so treat the price as a reflection of the tests you actually need rather than a measure of quality.
How often should I be screened?
For most people in good health with normal results, repeating the core screen every one to three years is reasonable, with the interval shortened if you have risk factors or are on treatment. Some tests do not need repeating on that cycle. Lp(a), for instance, is essentially a one-off, and a calcium score is not something we repeat frequently. If a screen finds a problem and you start medication or change your lifestyle, follow-up is essential to check that the treatment is working and to adjust it. Screening is not a single event; it is part of looking after your heart over the long term.
The bottom line
Heart disease is the leading cause of death in Singapore, and it usually develops silently. A good heart screening finds the warning signs early (high blood pressure, harmful cholesterol, diabetes, and hidden plaque) while there is still plenty you can do about them. But the best screen is the one matched to your risk: thorough where it needs to be, and sensibly restrained where it does not. The most important step is to have your risk assessed properly rather than guessing, or assuming you are too young or too well to bother.

Frequently asked questions
At what age should I start heart screening in Singapore?
For most healthy people I suggest thinking about a baseline screen from around their 40s. Start earlier if you have risk factors such as high blood pressure, high cholesterol, diabetes, smoking, or a family history of early heart disease. Because coronary disease can appear at a younger age in our region, do not assume you are too young to be checked.
Do I need every test in a comprehensive package?
No, and that is an important point. The right package depends on your risk. A young, healthy person usually needs only blood pressure, blood tests, and an ECG, while someone at higher risk may benefit from a calcium score, stress test, or CT coronary angiogram. More tests are not automatically better, because the tests should follow your risk.
What is the difference between a CT calcium score and a CT coronary angiogram?
A calcium score is a quick scan with no injection that measures calcified plaque and gives a single risk number, very useful for clarifying risk in people in the middle. A CT coronary angiogram uses a contrast dye to show the arteries in detail, including actual narrowings, and is the more powerful test, usually reserved for people with symptoms or higher risk.
How much does a heart screening cost in Singapore?
It varies widely depending on which tests are included, from a basic blood-and-blood-pressure check up to a full work-up with imaging. The most useful approach is to have a cardiologist recommend the right tests for your risk first, then price the package accordingly. As a guide, expect a range from around $450 up to about $3,500 depending on the tests included.
How often should I repeat a heart screening?
For most healthy people with normal results, every one to three years is reasonable, sooner if you have risk factors or are on treatment. Some tests are one-offs: Lp(a) is essentially measured once in a lifetime, and a calcium score is not repeated often. If a problem is found, regular follow-up matters to check that treatment is working.
