Vomiting with Heart Pain: Causes, Risks, and First Aid

Vomiting with heart pain is not a standalone diagnosis, but rather a disturbing combination of symptoms that can occur with acute coronary syndrome, myocardial infarction, unstable angina, arrhythmia, pulmonary embolism, aortic dissection, severe high blood pressure, and some non-cardiac conditions. The main danger is that nausea and vomiting can disguise a cardiac event as "stomach ache," "poisoning," or "heartburn," especially if the pain is not severe or is not located directly behind the breastbone. [1]

In acute coronary syndrome, blood flow to the heart muscle is suddenly reduced, and in a heart attack, part of the heart muscle begins to be damaged or die due to a lack of oxygen. The Mayo Clinic clearly states that acute coronary syndrome often causes chest pain or discomfort, nausea or vomiting, upper abdominal pain, shortness of breath, cold sweats, dizziness, fainting, and unusual fatigue. [2]

The presence of vomiting does not make a cardiac cause "less likely." The UK's National Institute for Health and Care Excellence classifies chest pain associated with nausea and vomiting, severe sweating, or shortness of breath as symptoms that may indicate acute coronary syndrome. This is especially important if the pain lasts longer than 15 minutes, comes in waves, or radiates to the arm, back, neck, jaw, or upper abdomen. [3]

The American Heart Association also lists nausea as a possible sign of a heart attack, and for women, it specifically lists vomiting, upset stomach, shortness of breath, shoulder, back, or arm pain, unusual weakness, and fatigue. This doesn't mean women don't experience chest pain: chest pain or discomfort remains a common symptom, but additional signs are often confusing. [4]

The rule of thumb is simple: if chest pain or a feeling of "heartache" is accompanied by vomiting, cold sweat, shortness of breath, weakness, dizziness, fainting, heart rhythm disturbances, fear of death, or pain radiating to the arm, back, neck, jaw, or upper abdomen, call emergency services. Avoid driving to the hospital on your own, as your condition could worsen rapidly en route. [5]

Combination of symptoms	Why is it dangerous?	What to do
Chest pain plus vomiting	It could be acute coronary syndrome.	Call emergency help
Pain plus cold sweat	A common warning sign of coronary heart disease	Don't wait for improvement
Pain plus shortness of breath	Heart attack, pulmonary embolism, and heart failure are possible.	Urgent assessment
Pain radiating to the arm, back, neck, or jaw	Typical distribution area of ischemic pain	Urgently to the hospital by ambulance
Pain plus fainting or sudden weakness	Arrhythmia, shock, aortic dissection, massive thromboembolism are possible.	Urgently
Only stomach pain and vomiting in a person with risk factors	A heart attack can mimic an indigestion problem.	A medical assessment is needed

Code according to ICD 10 and ICD 11

There is no single universal code for vomiting associated with heart pain, as it is coded based on the specific cause: vomiting, chest pain, myocardial infarction, angina, pulmonary embolism, aortic dissection, or another condition. The International Classification of Diseases is used to record diagnoses and statistics, but the clinical formulation should reflect the actual cause, not just the patient's complaint. [6]

In the International Classification of Diseases, 10th revision, acute myocardial infarction is classified as I21, angina as I20, chest pain as R07, nausea and vomiting as R11, pulmonary embolism as I26, and aortic dissection is usually coded in group I71. In the International Classification of Diseases, 11th revision, acute myocardial infarction is classified as BA41, angina as BA40, nausea or vomiting as MD90, vomiting as MD90.1, acute pulmonary thromboembolism as BB00.0, and diseases of aorta with aneurysm or dissection as BD50. [7]

Clinical situation	International Classification of Diseases, 10th revision	International Classification of Diseases, 11th revision	Comment
Vomiting as a symptom	R11	MD90 or MD90.1	Used if the cause has not yet been established
Chest pain as a symptom	R07	Coded by symptom section or underlying cause	Need further diagnostics
Angina pectoris	I20	BA40	Pain due to temporary myocardial ischemia
Acute myocardial infarction	I21	BA41	Heart muscle damage due to acute ischemia
Unstable angina	I20.0	BA40.0 in a number of coding systems	Part of the spectrum of acute coronary syndrome
Pulmonary embolism	I26	BB00.0 for acute pulmonary thromboembolism	May cause chest pain, shortness of breath, weakness
Aortic dissection	I71.0 in the International Classification of Diseases, 10th revision	BD50 with clarification of localization and complications	Simulates a heart attack and requires urgent diagnosis.

Why does nausea and vomiting occur with heart pain?

Nausea and vomiting associated with cardiac ischemia are related to neural reflexes and the body's general stress response to a lack of oxygen in the heart muscle. The heart, esophagus, stomach, and upper abdomen have intersecting neural pathways for perceiving pain and discomfort, so a heart attack is sometimes felt as "stomach" pain, heartburn, heaviness, nausea, or vomiting. [8]

During a myocardial infarction, the body activates the sympathetic nervous system, causing cold sweats, weakness, anxiety, palpitations, pallor, and dizziness. Simultaneously, the vagus nerve and gastrointestinal reflexes may be activated, especially if the lower wall of the heart is affected, sometimes manifesting as nausea, vomiting, a slow pulse, or a feeling of severe weakness. [9]

Vomiting can be especially misleading when the pain is localized in the upper abdomen. The Mayo Clinic notes that pain from acute coronary syndrome can radiate to the upper abdomen, and symptoms may include nausea, vomiting, and pain or burning in the upper abdomen, similar to indigestion. Therefore, "feels like my stomach" does not rule out a cardiac cause. [10]

In older adults, people with diabetes, and women, heart attack symptoms may be less typical. Pain may be mild, pressing, burning, or absent, while shortness of breath, weakness, nausea, vomiting, sweating, altered consciousness, or unusual fatigue may become more prominent. The CDC specifically notes that nausea or vomiting can be other symptoms of a heart attack, and these symptoms are more common in women. [11]

But vomiting accompanied by chest pain isn't limited to heart attacks. It can accompany aortic dissection, pulmonary embolism, severe hypertensive reactions, pancreatitis, biliary colic, ulcerative bleeding, esophageal spasm, reflux, anxiety attacks, and poisoning. Therefore, diagnosis should begin with ruling out dangerous cardiovascular causes, rather than assuming "it's just my stomach." [12]

Mechanism	How does it manifest itself?	Why is this important?
Cardiac ischemia	Pressure, burning, pain, weakness, sweat, vomiting	It could be a heart attack.
Nervous reflexes	Nausea, vomiting, weakness, sometimes a slow pulse	Often confusing
Referred pain	Pain in the upper abdomen, back, jaw, or arm	Heart pain is not always felt in the center of the chest.
Stress response	Cold sweat, anxiety, trembling, palpitations	Increases nausea
Concomitant reflux or gastritis	Heartburn, sour belching, nausea	May simulate heart pain
Other vascular accidents	Fainting, sharp pain, shortness of breath, vomiting	Urgent diagnostics are needed

How to distinguish a heart attack from a stomach attack

It's impossible to completely differentiate a heart attack from a gastric cause based on pain alone. Even doctors don't make a diagnosis based solely on pain descriptions: an electrocardiogram, cardiac troponins, and a risk assessment are needed. The 2022 American College of Cardiology Guidelines for Chest Pain in the Emergency Department emphasize the need for a structured assessment rather than an intuitive decision based on a single symptom. [13]

Symptoms that suggest a cardiac cause include pain, pressure, squeezing, burning, or heaviness behind the breastbone, lasting more than a few minutes, recurring in bouts, associated with exertion or stress, and radiating to the left or right arm, shoulder, neck, jaw, back, or upper abdomen. Worrisome accompanying symptoms include vomiting, cold sweat, shortness of breath, weakness, dizziness, fainting, and a feeling of irregular heartbeat. [14]

A gastrointestinal cause may be suggested by acid belching, a connection with very large or acidic foods, worsening when lying down, relief from antacids, and a burning sensation behind the breastbone without cold sweat or shortness of breath. However, this isn't a foolproof rule: a heart attack can also feel like heartburn or indigestion, and the Mayo Clinic specifically lists pain or burning in the upper abdomen among the symptoms of acute coronary syndrome. [15]

The response to nitroglycerin or antacid should not be used as a home test. NICE specifically states that the response to glyceryl trinitrate should not be used to diagnose acute coronary syndrome. Similarly, temporary relief after stomach medication does not rule out a cardiac cause if the initial symptoms were severe. [16]

Waiting is especially dangerous if a person has risk factors: age over 45-50, smoking, high blood pressure, diabetes, high cholesterol, obesity, chronic kidney disease, previous angina, heart attack, stroke, or a family history of early cardiovascular events. The CDC lists high blood pressure, high cholesterol, and smoking among the key risk factors for heart disease and heart attack. [17]

Sign	More alarming is the direction of the heart.	More like a digestive cause, but doesn't rule out heart
The nature of pain	Pressure, squeezing, heaviness, burning	Sour burps, food related
Duration	More than 15 minutes or in waves	Briefly and clearly after meals
Spreading	Arm, shoulder, back, neck, jaw, upper abdomen	Usually locally in the upper abdomen
Associated symptoms	Vomiting, cold sweat, shortness of breath, weakness, fainting	Belching, bloating, sour taste
Patient risk	Diabetes, hypertension, smoking, previous heart attack	There are no risk factors, but this is not a guarantee
Tactics	Urgent help	Medical evaluation if symptoms are unusual or recurring

Other dangerous causes of chest pain with vomiting

Pulmonary embolism can cause chest pain, sudden shortness of breath, rapid breathing, cough, hemoptysis, rapid heartbeat, weakness, dizziness, and fainting. The European Society of Cardiology describes chest pain as a common symptom of pulmonary embolism, and the International Classification of Diseases, 11th revision, defines acute pulmonary embolism as partial or complete blockage of a branch of the pulmonary artery with acute symptoms including shortness of breath, rapid breathing, chest pain, cough, and blood-tinged sputum.[18]

Aortic dissection can mimic a heart attack. The classic symptom is sudden, severe chest or back pain, often described as tearing or stabbing, sometimes accompanied by syncope, neurological symptoms, pressure differences between the arms, abdominal pain, or signs of shock. The Merck Manual emphasizes that aortic dissection should be considered in patients with chest pain, back pain, unexplained syncope, abdominal pain, stroke, or acute heart failure, especially if the pulse or pressure between the extremities is unequal. [19]

Acute pancreatitis and biliary colic can also cause upper abdominal pain, nausea, vomiting, and a feeling of "heartache," especially if the pain radiates to the back or occurs after fatty foods. However, if this occurs, self-medication for the stomach should not be attempted if there is chest pressure, sweating, shortness of breath, weakness, or cardiac risk factors. Risky cardiovascular causes must first be ruled out. [20]

Heart rhythm disturbances can cause a feeling of irregular heartbeat, palpitations, weakness, nausea, dizziness, chest discomfort, and fainting. If vomiting occurs alongside sudden heart palpitations, irregular heartbeats, a drop in blood pressure, or loss of consciousness, it does not resemble a common gastrointestinal disorder and requires urgent evaluation. [21]

An anxiety attack can cause chest pain or tightness, nausea, tremors, sweating, rapid heartbeat, and fear of death. However, a diagnosis of an anxiety attack should not be made until a heart attack, pulmonary embolism, aortic dissection, and dangerous arrhythmias have been ruled out, especially if symptoms are new, vomiting, shortness of breath, fainting, or a high cardiovascular risk are present. [22]

Possible cause	Typical tips	Why you can't pull
Myocardial infarction	Chest pressure, vomiting, sweating, shortness of breath, radiating pain	The sooner blood flow is restored, the less damage to the heart
Unstable angina	New pain or worsening of existing angina	It may develop into a heart attack.
Pulmonary embolism	Sudden shortness of breath, pain, fainting, coughing up blood	Acute overload of the right heart is possible
Aortic dissection	Sudden tearing pain, fainting, neurological signs	Requires urgent imaging and treatment.
Arrhythmia	Interruptions, palpitations, weakness, fainting	May cause circulatory arrest
Pancreatitis or biliary colic	Upper abdomen, vomiting, back pain	May require urgent care, but the heart must be ruled out

What to do before the ambulance arrives

If chest pain or "heart pain" is accompanied by vomiting, cold sweat, shortness of breath, weakness, fainting, radiating pain, or unusual fatigue, call your local emergency number immediately. The American Heart Association clearly states that minutes matter, and calling an ambulance allows for treatment to begin before arriving at the hospital and for the patient to be transported to the emergency department more quickly. [23]

Until help arrives, it's best for the person to stop any activity, sit or lie down with the upper body elevated, ensure access to air, loosen tight clothing, and avoid eating. If vomiting occurs, it's important to turn the head to the side or choose a position that reduces the risk of vomit entering the respiratory tract, especially if the person is weak, drowsy, or near-fainting. [24]

Do not drive yourself or take someone to the hospital by taxi if there are signs of a possible heart attack or other cardiovascular emergency. The heart rhythm may suddenly become abnormal, blood pressure may drop, vomiting may recur, and CPR or defibrillation may be required en route. The CDC notes that in some cases, a heart attack requires CPR or an electrical shock to restore heart function. [25]

Avoid taking antiemetics, painkillers, stomach medications, or additional heart medications without the advice of a doctor or emergency services dispatcher. Such medications may interfere with the diagnosis, worsen blood pressure, interact with existing medications, or delay proper treatment. If the patient already has prescribed medications for an angina attack, they should be used according to the prescribed plan. However, if vomiting, weakness, or a suspected heart attack occur, calling an ambulance remains the first step. [26]

If a person has lost consciousness, is not breathing normally, or is breathing in short, gasping breaths, CPR should be initiated immediately and an automated external defibrillator (AED) should be used if available. The American Heart Association emphasizes the importance of being prepared for CPR in cardiac events because a nearby bystander can be crucial until emergency help arrives. [27]

Action	Why is it important?	A mistake to avoid
Call emergency help	In a heart attack, time determines the extent of damage to the heart.	Wait for it to "pass"
Stop the load	Reduces the heart's need for oxygen	Walking, climbing stairs, "pacing"
Sit or lie down in a semi-sitting position	May make breathing easier and reduce the risk of falls	Lie on your back if vomiting occurs again.
Don't eat or drink a lot	Vomiting may recur.	Trying to "wash out the stomach"
Do not drive	Arrhythmia, fainting, and cardiac arrest are possible.	Go yourself
Follow the dispatcher's instructions	Helps you wait for help safely	Taking medications haphazardly

Diagnostics in the hospital

The first test performed if acute coronary syndrome is suspected is a 12-lead electrocardiogram (ECG). Current guidelines for acute coronary syndrome emphasize early recognition of ST-segment elevation infarction and other dangerous changes, as this is essential for prompt restoration of blood flow. A review of key points from the 2025 guidelines states that an ECG should be performed and interpreted within 10 minutes of initial medical contact if acute coronary syndrome is suspected. [28]

The second key test is high-sensitivity cardiac troponin. Elevations and changes in troponin levels help confirm heart muscle damage, but a normal early result alone does not always rule out a heart attack if symptoms have recently begun. The American College of Cardiology's guidelines for chest pain in the emergency department support the use of accelerated clinical algorithms with high-sensitivity troponin to safely rule out or confirm a heart attack. [29]

The doctor also evaluates blood pressure, pulse, oxygen saturation, signs of heart failure, murmurs, pulse symmetry in the extremities, neurological symptoms, abdominal tenderness, and signs of venous thrombosis. This is necessary because vomiting with chest pain can be associated not only with a heart attack, but also with aortic dissection, pulmonary embolism, arrhythmia, pancreatitis, or bleeding. [30]

Echocardiography, chest X-ray, coronary CT angiography, aortic CT scan, pulmonary CT angiography, D-dimer analysis, complete blood count, biochemistry, coagulation parameters, and other tests are used as indicated. The choice depends on the most likely cause based on symptoms and examination. [31]

If a heart attack or high risk of acute coronary syndrome is confirmed, treatment is aimed at restoring blood flow, preventing thrombus growth, pain control, and preventing arrhythmias and complications. The European Society of Cardiology, in its 2023 guidelines, emphasizes the comprehensive patient care pathway for acute coronary syndrome: from diagnosis and early risk stratification to antithrombotic therapy, invasive evaluation, revascularization, and subsequent long-term management. [32]

Examination	Why is it necessary?	What can it show?
12-lead electrocardiogram	Quickly identify signs of ischemia and infarction	ST segment elevation or depression, rhythm disturbances
High-sensitivity troponins	Find damage to the heart muscle	Infarction or other myocardial injury
Blood oxygen saturation	Assess respiratory failure	Thromboembolism, pulmonary edema, severe cardiac cause
Echocardiography	Assess the work of the heart	Contractility disorders, complications of infarction
Computed tomography angiography	Find a thrombus, dissection, or other vascular cause	Pulmonary embolism, aortic dissection
Blood tests	Assess anemia, kidneys, electrolytes, inflammation	Complications of vomiting and associated causes

Treatment: Why you shouldn't limit yourself to antiemetic drugs

When vomiting occurs alongside heart pain, it's important to treat the underlying cause, not the vomiting itself. If it's acute coronary syndrome, the primary goal is to restore blood flow to the heart muscle and prevent complications; if it's pulmonary embolism, restore and maintain pulmonary circulation; if it's aortic dissection, urgently monitor hemodynamics and determine the need for surgical or endovascular treatment. [33]

Antiemetic medications can temporarily reduce nausea, but they won't stop a heart attack or dissolve a clot in a coronary or pulmonary artery. Furthermore, self-administration of medications can delay emergency medical attention and worsen the prognosis. The CDC emphasizes that the sooner a person with signs of a heart attack gets to the emergency room, the sooner treatment can begin to reduce damage to the heart muscle. [34]

In ST-segment elevation myocardial infarction, the priority is urgent reperfusion, that is, restoration of blood flow in the occluded coronary artery. In non-ST-segment elevation myocardial infarction and unstable angina, the management strategy depends on the risk, troponin dynamics, electrocardiogram, patient condition, and comorbidities. The 2025 guidelines of the American College of Cardiology and the American Heart Association updated approaches to the treatment of acute coronary syndrome, including medical and invasive management. [35]

If vomiting is severe or recurrent, doctors additionally monitor fluid levels, electrolytes, renal function, and the risk of aspiration. Potassium is especially important, as its imbalances can increase the risk of arrhythmias, and in the case of a cardiac event, this is of additional importance. Such correction is performed in parallel with treatment of the underlying cardiovascular cause, not instead of it. [36]

After stabilization, prevention of recurrence is important: control of blood pressure, cholesterol, and diabetes, smoking cessation, cardiac rehabilitation, regular use of prescribed medications, and follow-up with a physician. The European Society of Cardiology notes that current guidelines for acute coronary syndrome cover not only initial treatment but also long-term management after hospitalization. [37]

Confirmed cause	The main goal of treatment	Why is antiemetic not enough?
Myocardial infarction	Restore blood flow and limit damage to the heart	Vomiting is secondary to ischemia
Unstable angina	Prevent a heart attack	Risk assessment and antithrombotic therapy are needed.
Pulmonary embolism	Prevent blood clot growth and heart strain	Vomiting is not the main danger
Aortic dissection	Prevent organ rupture and ischemia	Urgent vascular tactics are needed
Arrhythmia	Restore a safe rhythm or rate	Vomiting may be due to low blood flow.
Gastric cause after ruling out heart	Eliminate reflux, ulcers, gallbladder or other causes	The heart must first be ruled out if the picture is alarming.

Who is at high risk?

The risk of heart attack and serious cardiovascular events is higher in people with high blood pressure, high cholesterol, smoking, diabetes, obesity, physical inactivity, chronic kidney disease, and a family history of early heart attack or stroke. The Mayo Clinic lists these factors among the risk factors for acute coronary syndrome, and the CDC highlights high blood pressure, high cholesterol, and smoking as key risk factors for heart disease and heart attack. [38]

In women, older adults, and patients with diabetes, a heart attack may present with more subtle symptoms, such as weakness, shortness of breath, nausea, vomiting, back pain, neck pain, jaw pain, unusual fatigue, or an upset stomach, rather than the classic severe pain. The American Heart Association specifically warns that in women, symptoms may be less obvious and are mistakenly attributed to acid reflux, the flu, or aging. [39]

In patients with known coronary artery disease, a history of heart attack, stenting, bypass surgery, or angina, a new combination of pain, vomiting, and sweating should be taken especially seriously. Even if similar attacks have resolved previously, a sudden increase, longer duration, lesser relationship with exercise, or occurrence at rest may indicate an unstable situation. [40]

Certain factors increase the likelihood of pulmonary embolism: recent surgery, prolonged immobility, flying or traveling with prolonged sitting, deep vein thrombosis, active cancer, pregnancy, the postpartum period, estrogen use, and hereditary thrombophilias. These factors help a doctor detect pulmonary embolism if chest pain, shortness of breath, weakness, and vomiting are present. [41]

The most significant factors for aortic dissection are long-standing hypertension, connective tissue diseases, known aortic aneurysm, bicuspid aortic valve, previous aortic surgery, and a family history of aortic disease. Sudden, severe chest or back pain with vomiting, syncope, or neurological symptoms in this risk group requires immediate diagnosis. [42]

Risk group	Why is it important?
People with hypertension	Higher risk of heart attack, heart failure and aortic dissection
People with diabetes	A heart attack may have a less typical course.
Smokers	Higher risk of coronary thrombosis and vascular events
Women after menopause	Less obvious symptoms of a heart attack may occur
Elderly people	More often, the picture is atypical and the risk of complications is higher.
People after surgery or prolonged immobility	Higher risk of pulmonary embolism
Patients with known angina	A change in the nature of pain may be a sign of instability

Prevention of recurrence after examination

If testing confirms a cardiac cause, prevention focuses on long-term cardiovascular risk reduction. This typically includes controlling blood pressure, cholesterol, and sugar levels, quitting smoking, engaging in regular physical activity with a doctor's approval, eating a diet low in saturated fat and excess salt, losing weight if obese, and taking prescribed medications. [43]

Following a heart attack or high-risk acute coronary syndrome, antithrombotic drugs, statins, blood pressure medications, diabetes treatment, cardiac rehabilitation, and surveillance are essential. The 2025 American College of Cardiology/American Heart Association Guidelines for Acute Coronary Syndrome update medical and procedural management practices, and the European Society of Cardiology emphasizes the importance of long-term posthospital management. [44]

If a heart condition is ruled out, but pain and vomiting recur, don't be complacent; instead, look for another cause: gastroesophageal reflux, peptic ulcer, gallstones, pancreatitis, gastric motility disorders, medication side effects, or anxiety disorder. However, a diagnosis of "non-heart" should be the result of an evaluation, not a quick guess at the first sign of a dangerous episode. [45]

For patients with recurring episodes, it is helpful to record the time of pain, its duration, its relationship to exercise and food, the nature of the pain, its radiating effects, the presence of vomiting, sweating, shortness of breath, pulse, blood pressure, and medications taken. Such a diary does not replace urgent care for dangerous symptoms, but it helps the doctor distinguish between angina, reflux, arrhythmia, panic attacks, and other causes. [46]

The most common and dangerous mistake is to "tough it out" the first episode and seek medical attention only the next day. In a heart attack, the time without restoration of blood flow is associated with greater damage to the heart muscle; the CDC clearly states that the longer it takes without treatment to restore blood flow, the greater the damage to the heart muscle. [47]

The purpose of prevention	Practical measures
Reduce the risk of heart attack	Control blood pressure, cholesterol, sugar, and stop smoking
Prevent a recurrent coronary episode	Taking prescribed medications, rehabilitation, observation
Don't miss thromboembolism	Assessing the risk of thrombosis after surgery and immobility
Don't miss aortic dissection	Hypertension control and aneurysm monitoring
Distinguish gastric causes	Examination for repeated vomiting and upper abdominal pain
Speed up help with a new episode	A written action plan and understanding warning signs

Frequently asked questions

Can a heart attack cause vomiting?

Yes. Nausea and vomiting are among the possible symptoms of acute coronary syndrome and heart attack, especially if there is chest pain or discomfort, shortness of breath, cold sweat, weakness, dizziness, or pain radiating to the arm, back, neck, jaw, or upper abdomen.[48]

If the pain is like heartburn, can I take some stomach medicine first?

If heartburn is accompanied by vomiting, cold sweats, shortness of breath, weakness, radiating pain, or a high cardiac risk, home treatment should not be attempted. Acute coronary syndrome can be felt as pain or burning in the upper abdomen, so cardiac causes should be ruled out first. [49]

Why do women sometimes mistake a heart attack for a stomach attack?

In women, chest pain remains a common symptom, but additional symptoms may more often include shortness of breath, nausea, vomiting, upset stomach, back, shoulder, or arm pain, unusual fatigue, and weakness. The American Heart Association warns that such symptoms may be less obvious and therefore mistakenly attributed to reflux, the flu, or fatigue. [50]

Is it possible to get to the hospital on your own?

No, if a heart attack or other cardiovascular emergency is suspected. The American Heart Association points out that calling an ambulance allows for treatment to begin sooner, and people with chest pain who arrive by ambulance can get treatment in the hospital more quickly. [51]

If vomiting has stopped, but the pain lasts for 20 minutes, do I need to seek medical attention?

Yes. NICE recommends urgent assessment if acute coronary syndrome is suspected, even if pain has resolved, especially if the episode occurred within the last 12 hours and an electrocardiogram (ECG) is not performed or is abnormal. Resolving pain does not rule out a heart attack or unstable angina. [52]

Can pulmonary embolism cause chest pain and vomiting?

Yes, although the most common symptoms are sudden shortness of breath, chest pain, rapid breathing, cough, sometimes blood in the sputum, weakness, or fainting. The European Society of Cardiology describes chest pain as a common symptom of pulmonary embolism, and the International Classification of Diseases, 11th revision, associates acute pulmonary embolism with shortness of breath, rapid breathing, chest pain, cough, and bloody sputum. [53]

What tests are most important for heart pain and vomiting?

In the first few minutes, a 12-lead electrocardiogram (EKG), high-sensitivity cardiac troponin (HSC), and assessment of blood pressure, pulse, oxygen saturation, and overall health are essential. Echocardiography, computed tomography angiography, blood tests, and other tests are also performed as needed to rule out pulmonary embolism, aortic dissection, and non-cardiac causes. [54]

Can I take an antiemetic and see?

No, if vomiting is accompanied by chest pain, cold sweat, shortness of breath, weakness, radiating pain, fainting, or high cardiac risk. Antiemetics do not treat heart attack, pulmonary embolism, or aortic dissection and may delay seeking help. [55]

Key points from experts

Sunil V. Rao, MD, professor of medicine at NYU Grossman School of Medicine, director of interventional cardiology at NYU Langone Health, and chair of the 2025 Acute Coronary Syndrome Guidelines Task Force. His key message is that acute coronary syndrome requires early recognition and standardized treatment because current decisions about medical therapy and invasive strategies impact survival and the risk of recurrent events. [56]

Robert A. Byrne, Professor of Cardiovascular Research at the Royal College of Surgeons in Ireland, Director of Cardiology at the Mater Private Network, and Chair of the European Society of Cardiology 2023 Guidelines Task Force on Acute Coronary Syndrome, said: "The practical implication of these guidelines is that patients with suspected acute coronary syndrome should be managed as part of a continuum—from early diagnosis and risk assessment to antithrombotic therapy, invasive evaluation, revascularization, and long-term follow-up." [57]

Martha Gulati, MD, MS, chair of the 2021 Chest Pain Assessment Guidelines Task Force. The key message for vomiting in cardiac pain is that chest pain should be assessed in a structured manner, taking into account risk, electrocardiogram (ECG), troponins, and the likelihood of dangerous causes, rather than based on a subjective impression that symptoms "feel like stomach pain." [58]

Helen Reddel, a physician and respiratory medicine researcher, chairs the scientific committee of the Global Initiative for Asthma. Her approach is important for differential diagnosis: shortness of breath and chest discomfort do not always indicate a heart attack, but when combined with vomiting and weakness, dangerous cardiovascular causes must first be ruled out, and only then asthma, bronchospasm, and other respiratory conditions should be considered. [59]

Michelle L. O'Donoghue, MD, MPH, is an associate professor of medicine at Harvard Medical School, a cardiologist at Brigham and Women's Hospital, and an investigator in the Thrombolysis in Myocardial Infarction Study Group. Her research is important to the topic of atypical manifestations of heart attack, including symptoms in women: nausea, vomiting, fatigue, and extra-chest discomfort should not be discounted if there is a possibility of cardiac ischemia. [60]

Result

Vomiting with chest pain is an alarming combination that could indicate myocardial infarction, unstable angina, pulmonary embolism, aortic dissection, dangerous arrhythmia, or another serious cause. Even if the symptoms resemble heartburn or food poisoning, vomiting accompanied by chest pain, sweating, shortness of breath, weakness, or radiating pain requires urgent evaluation. [61]

The main rule is not to wait for or treat vomiting separately. If you suspect a heart attack, call emergency services, stop exercising, avoid driving, avoid eating or drinking excessively, avoid taking random medications, and follow the dispatcher's instructions. [62]

In the hospital, the diagnosis is confirmed or ruled out using an electrocardiogram, high-sensitivity troponin, examination, monitoring, and additional tests as indicated. The sooner the underlying cause is identified, the greater the chance of preventing heart damage, severe complications, and death. [63]
