Is there a heart attack test you can do at home?

If you suspect a heart attack, call 112 first, even if you’re unsure (IQWiG, 2021). The emergency department will then determine whether you’re having a heart attack, using an ECG as the most important examination (BMG, 2020) and a troponin blood test, which is usually performed more than once (MedlinePlus, 2023).

The pressure in your chest starts in the evening, and your first thought is to wait and visit the doctor’s office tomorrow. The Institute for Quality and Efficiency in Health Care (IQWiG) advises against exactly that: if symptoms occur at night, you should never wait until the next morning (IQWiG, 2021). Call 112 to request an ambulance with an emergency physician, not your family doctor’s out-of-hours or on-call service, according to the Federal Ministry of Health’s National Health Portal (BMG, 2020).

IQWiG explains the urgency this way: “Every minute counts to initiate life-saving measures and limit consequential damage” (IQWiG, 2021). The National Health Portal also offers an encouraging statistic: In Germany, about three out of four people now survive a heart attack (BMG, 2020).

In the emergency department, tests are then carried out to determine whether a heart attack has occurred. According to the National Health Portal, the most important is an electrocardiogram, or ECG (BMG, 2020). A blood test for troponin is also performed. Troponin is a protein from heart muscle cells that enters the blood when the heart muscle is damaged (MedlinePlus, 2023).

There’s something else you can do at home: get your risk levels measured in your blood. These levels don’t tell you whether a heart attack is happening right now. They show how known risk factors, such as cholesterol levels, are looking (BMG, 2020). The blood values involved and how reliable the studies are are explained below.

How can you recognize a heart attack?

The most common signs of a heart attack are a pressing tightness in the chest and shortness of breath (IQWiG, 2021). Other typical symptoms include pain that lasts for more than five minutes and does not improve with rest (IQWiG, 2021).

Typical signs according to IQWiG (2021)

• A strong feeling of tightness or pressure in the chest
• Stabbing or burning pain behind the breastbone
• Pressing pain behind the breastbone
• Pain that radiates to the left or right arm
• Pain that radiates to the back or upper abdomen
• Pain that radiates to the throat
• Pain or numbness in the upper body that can radiate to the shoulder blades or neck
• Pain or numbness that can radiate to the jaw

Symptoms often start suddenly, but they can also develop gradually (IQWiG, 2021). IQWiG also lists other possible signs (IQWiG, 2021).

Other possible signs according to IQWiG (2021)

• Shortness of breath
• Nausea or vomiting
• Sweating or cold sweats
• Paleness
• Feeling weak or dizzy
• Unconsciousness
• Fear of death

Symptoms can look different in women. They experience the typical tightness in the chest less often and are more likely to have other symptoms such as shortness of breath or nausea (IQWiG, 2021). IQWiG also describes the same pattern in older people and people with diabetes or heart failure (IQWiG, 2021).

You don’t need to be certain to call emergency services; suspicion is enough (IQWiG, 2021). Anyone who hesitates because the symptoms don’t quite fit the textbook description loses time that matters during a heart attack.

Troponin test for a heart attack: What does it measure, and why is it done in the emergency department?

The troponin test measures a protein from heart muscle cells that enters the blood when the heart muscle is damaged (MedlinePlus, 2023). It is usually done in the emergency department, along with an ECG and other heart tests (MedlinePlus, 2023).

Normally, there is so little troponin in the blood that only the most sensitive tests can detect it (MedlinePlus, 2023). When the heart muscle is damaged, troponin passes from the cells into the blood, and the level rises (MedlinePlus, 2023). This is described in MedlinePlus, a health encyclopedia published by the U.S. National Library of Medicine.

The trend over time is what matters. An increase often does not show up until about 2 to 3 hours after the heart attack begins (MedlinePlus, 2023). So if the first level is within the normal range, it is usually measured again within the next 12 hours (MedlinePlus, 2023). Because troponin can continue to rise for up to about 24 hours after the onset, high levels are usually measured twice or more during this period (MedlinePlus, 2023).

For you, this means that if you have signs of a heart attack, calling emergency services immediately is crucial; in Germany, call 112 (MedlinePlus, 2023). The emergency department team will then take the measurements and repeat them.

However, an elevated troponin level does not always mean a heart attack (MedlinePlus, 2023). MedlinePlus lists the following among other possible causes (MedlinePlus, 2023):

• Heart rhythm disorders
• Heart failure
• Heart muscle inflammation
• Prolonged, intense exertion, such as running a marathon
• Chronic kidney disease
• Pulmonary embolism

There’s one thing you should know if you take dietary supplements. Biotin, also known as vitamin B7, can make your troponin level appear lower than it really is (MedlinePlus, 2023). This also applies to supplements that contain biotin. If you take something like this, tell your doctor before the test is done (MedlinePlus, 2023).

Which blood levels indicate an increased risk of a heart attack?

The National Health Portal lists high cholesterol and diabetes among the risk factors for a heart attack (BMG, 2020). Consensus statements from a professional society even describe a causal role for the blood lipid levels LDL cholesterol and lipoprotein(a) (Ference et al., 2017; Kronenberg et al., 2022).

Risk factors according to BMG (2020)

• smoking
• severe obesity
• high cholesterol
• high blood pressure
• diabetes
• increasing age

These factors also affect people who feel healthy: According to the National Health Portal, heart attacks also occur in people who had no symptoms beforehand (BMG, 2020). High blood pressure is also on the list, but is not a blood level. Learn more in the article about when blood pressure is considered normal.

The following blood levels have been studied to varying degrees. There are consensus statements from a professional society on blood lipids, while the other levels are covered by observational data.

How is LDL cholesterol linked to heart attack risk?

According to a consensus statement by the European Atherosclerosis Society, LDL cholesterol, one of the blood lipids, causes cardiovascular disease through atherosclerosis (Ference et al., 2017). A consensus statement is a joint assessment of the evidence by a committee of the professional society.

The relationship follows a clear rule: The more LDL cholesterol there is and the longer the blood vessels are exposed to it, the higher the risk (Ference et al., 2017). This is based on analyses involving more than 2 million participants and over 150,000 cardiovascular events (Ference et al., 2017). The article above explains how LDL interacts with the other levels: how to read blood lipid levels together.

Why does lipoprotein(a) matter for heart attack risk?

According to a consensus statement by the same professional society, lipoprotein(a), a blood lipid particle, is a causal risk factor for cardiovascular disease (Kronenberg et al., 2022). This also applies when LDL cholesterol is very low (Kronenberg et al., 2022).

The explanation is based on studies involving hundreds of thousands of people and describes a continuous relationship: Risk increases as lipoprotein(a) concentration rises (Kronenberg et al., 2022). The professional society recommends measuring the level at least once in adults (Kronenberg et al., 2022).

What does the long-term blood sugar marker HbA1c have to do with heart attack risk?

In a US observational study, HbA1c, the long-term blood sugar marker, was associated with the risk of coronary heart disease (Selvin et al., 2010). Coronary heart disease is a heart condition with the same risk factors as a heart attack (BMG, 2020).

The study examined 11,092 adults without diabetes or cardiovascular disease (Selvin et al., 2010). With an HbA1c of 6.0 to under 6.5 percent, the risk of coronary heart disease was 1.78 times higher than with 5.0 to under 5.5 percent (Selvin et al., 2010). Even at 5.5 to under 6.0 percent, the factor was 1.23; at 6.5 percent and above, it was 1.95 (Selvin et al., 2010).

Notably, long-term blood sugar was more strongly associated with cardiovascular risk than fasting blood sugar (Selvin et al., 2010). Because this is an observational study, it shows an association, not a cause.

What does CRP show about heart attack risk?

CRP, an inflammation marker in the blood, was associated with the risk of coronary heart disease in an analysis of 54 long-term studies involving 160,309 people without vascular disease (Emerging Risk Factors Collaboration, 2010). For every threefold increase in CRP, the risk was 1.63 times higher when only age and sex were taken into account, and 1.37 times higher when traditional risk factors were included (Emerging Risk Factors Collaboration, 2010). The same marker was also associated with other conditions, such as stroke or deaths from lung disease (Emerging Risk Factors Collaboration, 2010). The authors say it is unclear what CRP means for such a wide range of conditions (Emerging Risk Factors Collaboration, 2010). The article on what CRP levels mean explains what a CRP level generally indicates.

What does homocysteine tell us about heart attack risk?

Homocysteine, a blood marker, predicts the risk of heart attack and stroke in healthy people only moderately well at best (Homocysteine Studies Collaboration, 2002). This is the finding of an analysis of 30 studies with 5,073 coronary heart disease events (Homocysteine Studies Collaboration, 2002).

In this article, homocysteine is one risk marker among others. The article on homocysteine levels and what they indicate describes what the level means in detail.

The table summarizes what studies show about each marker and how reliable the evidence is.

Blood risk markers and the evidence from studies

Blood lipids: Ference et al. (2017) and Kronenberg et al. (2022). Long-term blood sugar: Selvin et al. (2010). CRP: Emerging Risk Factors Collaboration (2010). Homocysteine: Homocysteine Studies Collaboration (2002).

Which heart markers can be measured at home?

You can have risk markers measured at home from capillary blood, meaning blood that you collect yourself with a finger prick. These values indicate a health status, not an acute heart attack.

The difference from the emergency department is the timing. The sample is sent to a lab, and the result is only available after laboratory analysis. That is the wrong approach if a heart attack is suspected, but suitable for checking your own risk factors.

These values can be useful in preparing for a conversation at your doctor’s office. You can bring numbers for your blood lipids and long-term blood sugar instead of a guess, and your doctor can interpret them. For lipoprotein(a), a consensus statement from the European Atherosclerosis Society recommends measuring the value at least once in adults (Kronenberg et al., 2022).

The Women’s Wellness Check and the Men’s Wellness Check from mybody®x (MYBODY Lab GmbH) measure, among other things, cholesterol profile and long-term blood sugar HbA1c from capillary blood, at €169.00 each (as of 20.10.2026; subject to change). Only the Men’s Wellness Check measures lipoprotein(a) and homocysteine. Neither test measures troponin, and results are only available days after the sample is sent. Laboratory analysis takes 3 to 5 business days after the sample arrives. The values can help you prepare for a doctor’s appointment and do not replace medical evaluation.

What are the limitations of risk levels?

For HbA1c and CRP, studies show an association with heart risk, but not causation (Selvin et al., 2010; Emerging Risk Factors Collaboration, 2010). The same applies to homocysteine (Homocysteine Studies Collaboration, 2002).

The reason lies in the study design. The data on these levels come from observational studies, which show that a level and a risk occur together. They cannot prove that the level causes the risk.

There are also limitations in the details. The HbA1c study examined 11,092 adults in the US, and included only Black and White participants (Selvin et al., 2010). The homocysteine analysis includes studies through 1999 and is dated 2002 (Homocysteine Studies Collaboration, 2002).

The consensus statements on LDL cholesterol and lipoprotein(a) also describe how higher levels increase risk, but their summaries do not specify target levels (Ference et al., 2017; Kronenberg et al., 2022). What your own results mean is something to discuss with your doctor.

And the sources are dated. The IQWiG page on symptoms is from 2021, with an update announced for 2026 (IQWiG, 2021). The National Health Portal page is from 2020 (BMG, 2020). MedlinePlus is a consumer health encyclopedia from the US. Where the page gives the emergency number, 112 applies in Germany (MedlinePlus, 2023).

One limitation concerns mybody®x blood tests themselves: they do not measure troponin and cannot replace emergency diagnostics. An elevated risk level indicates a risk, not certainty that a heart attack will occur.

Heart attack test at home: what you can take away

The emergency department determines whether you are having a heart attack with an ECG and a troponin test, which is repeated if needed (MedlinePlus, 2023). Your part in that moment is to make the call: if you suspect a heart attack, call 112 immediately, even at night and even if you’re unsure (IQWiG, 2021). At home, you can do something else: know your risk levels and discuss them at your doctor’s office. A normal risk level doesn’t change anything: if you have signs of a heart attack, call emergency services immediately.
