What are the symptoms of a heart attack?
A heart attack occurs when inadequate blood flow damages the heart muscle. Possible symptoms include:
- Chest discomfort: Pressure, tightness, burning or heaviness in the centre of the chest. Symptoms may persist or come and go; do not wait for a particular duration before seeking help.
- Spreading discomfort: Pain may affect either or both arms, the shoulders, neck, jaw, back or upper abdomen.
- Breathlessness: Difficulty breathing at rest or with little activity, with or without chest discomfort.
- Cold sweating: Unexplained sweating, sometimes with pale skin.
- Nausea and vomiting: These can accompany a heart attack and may be mistaken for a stomach problem.
- Dizziness or faintness: Feeling lightheaded, weak or close to fainting.
- Anxiety or a sense of impending danger: Marked unease may occur, but its presence does not mean the cause is only anxiety.
- Palpitations or an irregular heartbeat: Rhythm disturbances can occur during a heart attack.
- Unusual weakness: Sudden or unexplained fatigue, sometimes severe.
Can there be warning symptoms beforehand?
Some people experience symptoms before a heart attack; others have no warning. Symptoms occurring beforehand are sometimes called prodromal symptoms, but they are not specific enough to predict a heart attack reliably.
- Chest pressure with activity: Discomfort when walking uphill or climbing stairs that eases with rest can suggest angina and needs medical assessment.
- Unexplained fatigue: A new reduction in the ability to manage usual activities.
- Disturbed sleep: Waking with breathlessness warrants assessment and can have several causes.
- Lightheadedness: Episodes of dizziness, particularly with other concerning symptoms.
- Indigestion or upper-abdominal discomfort: Heart-related symptoms can sometimes resemble reflux or stomach upset.
- Recurrent chest discomfort: Repeated episodes of pressure or burning should not be dismissed.
New, worsening or resting chest discomfort can be an emergency. Seek prompt assessment for new symptoms; call emergency services for suspected heart attack. Early assessment can identify treatable disease, but not every heart attack can be predicted or prevented.
Can symptoms differ in women?
Chest pain or discomfort remains the most common symptom in women as well as men. Women may also have breathlessness, nausea, unusual fatigue or back and jaw discomfort, sometimes without prominent chest pain.
- Unusual fatigue: New tiredness that makes ordinary tasks more difficult.
- Breathlessness: Breathlessness can occur without chest discomfort.
- Back or jaw discomfort: Pain may affect the upper back, jaw, shoulders or arms.
- Nausea or vomiting: Symptoms may be mistaken for a digestive problem.
- Dizziness or faintness: Lightheadedness may also occur.
- Cold sweats and anxiety: These can be confused with a panic attack.
- Upper-abdominal pressure: This may be mistaken for reflux.
What is a silent heart attack?
A silent heart attack causes mild, unusual or unrecognised symptoms, or no obvious symptoms. It may only be recognised later during medical testing. The absence of severe pain does not mean there was no heart damage.
Possible subtle symptoms
- Unexplained tiredness
- Episodes of breathlessness
- Mild chest pressure mistaken for indigestion
- Discomfort in the shoulders, back or jaw
- Nausea or unexplained sweating
- Lightheadedness without an obvious cause
Who may be less likely to recognise typical symptoms?
- People with diabetes: Nerve damage can reduce pain sensation in some patients.
- Older adults
- People whose symptoms are mild or unusual, including some women
- People with other conditions that make symptoms harder to interpret
If you are concerned about an unrecognised heart attack, discuss assessment with a clinician. Tests should be chosen for your symptoms and risk; routine yearly ECG and echocardiography are not automatically necessary for everyone in these groups.
What are the symptoms in younger adults?
A heart attack can occur in younger adults. Symptoms may resemble those in older people, but young age can lead to dangerous reassurance or delayed help. New chest pressure, breathlessness or other warning signs need attention regardless of age.
- Sudden chest pain or pressure
- Discomfort spreading to an arm or the jaw
- Cold sweating and breathlessness
- Occasionally, the first recognised event is cardiac arrest, which requires immediate resuscitation.
Risk factors and causes in younger people
- Smoking
- Familial hypercholesterolaemia: Inherited high LDL cholesterol can cause premature coronary disease.
- Cocaine and other stimulant drugs
- Less common coronary artery disorders including spontaneous coronary artery dissection in some patients
- Other risks include high blood pressure, diabetes and adverse lifestyle factors
Can symptoms distinguish a heart attack from panic or reflux?
Chest discomfort has many possible causes. Panic attacks and reflux can resemble heart problems. Symptoms overlap, so the type or duration of pain cannot safely rule out a heart attack at home.
- May cause pressure, tightness or heaviness
- May spread to either arm, jaw, back or upper abdomen
- Can persist or come and go
- May occur at rest or with activity
- May involve sweating, breathlessness or nausea
- Absence of severe pain does not exclude it
- May cause chest discomfort of different types
- Can include tingling, palpitations and breathlessness
- Duration varies and is not a reliable diagnostic test
- Fear, trembling or a sense of losing control may occur
- May follow stress, but a trigger is not always obvious
- Improvement with breathing exercises does not rule out heart disease
- May cause discomfort or burning behind the breastbone
- Can occur with regurgitation or a sour taste
- Often worsens after meals or when lying down
- Symptoms can resemble heart-related discomfort
- Relief after an antacid does not reliably exclude a heart attack
- Medical assessment may still be needed
What should you do if you suspect a heart attack?
Take these steps while arranging emergency help:
- 1Call 112 in Turkey, or your local emergency number, immediately. Give your location and describe the symptoms clearly.
- 2Stop activity and rest in a comfortable supported position. Avoid unnecessary exertion.
- 3Do not drive yourself to hospital. A dangerous rhythm disturbance or loss of consciousness can occur on the way.
- 4Follow the emergency operator's advice about aspirin. Do not delay the call to find medicine. Mention any aspirin allergy, bleeding problem or advice not to take it; do not take it unless the operator or a healthcare professional recommends it.
- 5Use prescribed glyceryl trinitrate only as directed. Do not take someone else's medicine or use it as a reason to delay calling for help.
- 6Loosen restrictive clothing and wait in a safe, comfortable place.
- 7Ask someone to stay with you if possible and help emergency staff reach you, for example by safely unlocking the door.
What to avoid
- ❌ Driving yourself to hospital
- ❌ Waiting for symptoms to pass
- ❌ Giving food, drink or tablets to an unconscious person
- ❌ Trying forceful coughing as a treatment for a heart attack or cardiac arrest
- ❌ Taking someone else's medication
How can you help someone with suspected heart attack?
- Call 112 in Turkey, or the local emergency number. Explain the location and situation clearly.
- Help the person rest comfortably. A supported sitting position may be comfortable if they are awake; follow the operator's advice.
- Check responsiveness and breathing. Are they responding and breathing normally?
- If they are unresponsive and not breathing normally: Start CPR as directed by the emergency operator. Gasping is not normal breathing. For an adult, chest compressions are given in the centre of the chest at 100–120 per minute, about 5–6 cm deep. Do not delay CPR while trying to find a pulse.
- Ask someone to bring an AED if one is available. Switch it on and follow its spoken instructions. It will assess whether a shock is needed.
- Continue CPR as directed until help takes over or the person shows clear signs of recovery and normal breathing.
How is a heart attack diagnosed?
Emergency assessment combines symptoms, examination and tests, which may include:
- Electrocardiogram (ECG): An ECG is obtained promptly to look for signs of ischaemia or a dangerous rhythm. Certain findings require immediate treatment; a normal initial ECG does not exclude every heart attack.
- Troponin blood tests: Troponin is a marker of heart muscle injury. Results are interpreted with symptoms and ECG findings, and repeat samples may be needed. Raised troponin can have causes other than a heart attack.
- Echocardiography: Ultrasound can assess heart function and areas that are not contracting normally.
When indicated, coronary angiography shows the coronary arteries through a catheter introduced at the wrist or groin. A blocked artery may be treated with a stent. The need and timing depend on the clinical findings; angiography is not the only basis for diagnosis.
How long can symptoms last?
- During a heart attack: Symptoms may persist, fluctuate or return after easing. Their duration cannot safely exclude a heart attack.
- Angina: Some episodes improve with rest or prescribed treatment, but new or worsening symptoms need assessment.
- Coronary artery spasm: Episodes may be intermittent and can still be serious.
- After a stent or bypass surgery: New or worsening chest pain requires assessment. Severe pain, breathlessness, collapse or other warning signs need emergency help.
What increases the risk of a heart attack?
Some risk factors cannot be changed; others can be reduced or treated.
Factors you cannot change
- Age: Risk generally increases with age, but younger people can also have a heart attack.
- Sex: Coronary disease often develops earlier in men, while risk also rises in women with age.
- Family history: Premature coronary disease in a close relative can increase risk.
- Inherited conditions: Familial hypercholesterolaemia and other inherited lipid disorders can contribute.
Factors that can be changed or treated
- Smoking: Damages blood vessels and substantially increases cardiovascular risk.
- High blood pressure: Increases strain on the circulation and the risk of vascular disease.
- Unhealthy cholesterol levels: Raised LDL cholesterol is an important cause of atherosclerosis.
- Diabetes: Increases cardiovascular risk and requires individual management.
- Excess weight: Can be associated with high blood pressure, diabetes and adverse lipid levels.
- Physical inactivity: Contributes to cardiovascular risk and poorer general fitness.
- Stress and poor sleep: Can affect health and behaviours; persistent problems deserve attention.
- Excess alcohol: Can raise blood pressure and cause other heart problems.
- Unhealthy eating patterns: Diets high in salt, trans fats and heavily processed foods can contribute to risk.
When several risk factors occur together, overall cardiovascular risk can be higher; a clinician can assess the combined risk.
How can you reduce your risk?
Many cardiovascular events can be prevented by addressing risk factors, although prevention cannot guarantee that a heart attack will never occur.
Lifestyle measures
- Stop smoking: Risk falls after quitting and continues to improve over time; support and medication can help.
- Be physically active: Aim for regular activity appropriate to your health. A common adult target is 150 minutes of moderate activity each week, built up gradually and with clinical advice when needed.
- Work towards a healthy weight: Set realistic goals with your healthcare team; appropriate targets vary between individuals.
- Choose a heart-healthy eating pattern: Emphasise vegetables, fruit, whole grains, legumes, fish and unsaturated oils; limit processed meats and highly processed foods.
- Reduce salt: Limit salty foods and follow any personalised advice for blood pressure or heart failure.
- Manage stress and sleep: Regular sleep, relaxation and support for persistent anxiety or stress can help overall health.
Medical follow-up
- Blood pressure: Have it checked and agree an individual treatment target with your clinician.
- Cholesterol: Testing intervals and LDL targets depend on overall risk and whether cardiovascular disease is already present.
- Blood glucose: Screening and treatment targets depend on individual circumstances, including whether you have diabetes.
- Preventive reviews: Use symptoms, family history and risk factors to guide assessment. Routine ECG or exercise testing is not necessary for every symptom-free adult.
Medicines when indicated
- Statins: Lower LDL cholesterol and cardiovascular risk in appropriate patients.
- Low-dose aspirin: Do not start it routinely for prevention without medical advice; benefits must be weighed against bleeding risk.
- Blood pressure medicines: The most appropriate drug or combination depends on the individual.
Risk assessment, appropriate treatment and sustained healthy habits can reduce the likelihood of cardiovascular events.
