6 Warning Heart Attack Symptoms You Should Never Ignore

Why the Hours After Symptoms Begin Matter

A heart attack happens when a clot suddenly blocks a coronary artery. Heart muscle that is starved of oxygen begins to be damaged within minutes and is lost progressively over the next few hours. Treatments that reopen the artery, such as emergency angioplasty or clot-dissolving medicines, save the most muscle when given early. A patient who reaches hospital within the first hour or two has a much better chance of keeping a strong heart than one who arrives after a day. That is why doctors say "time is muscle".

Six Warning Symptoms

1. Pressure, tightness or heaviness in the chest

The most recognised symptom is not a sharp stab but a squeezing, tightening or fullness in the centre or left side of the chest, often described as a weight, a band or a hand clenching the heart. It lasts more than a few minutes, or fades and comes back. Pain that increases with exertion and eases with rest is a warning of narrowed arteries, and pain that occurs at rest is more worrying.

2. Pain that radiates to the arm, jaw, neck, back or stomach

Discomfort can spread to one or both arms (usually the left), the shoulder, neck, jaw or teeth, the upper back between the shoulder blades, or the upper abdomen. Some people feel only this referred pain, without any chest sensation, and may think they have a toothache, shoulder strain or indigestion.

3. Shortness of breath

Difficulty breathing or feeling as though you cannot get enough air, sometimes before or without chest discomfort, is a common sign. It can happen at rest or with minimal effort. It may be the main symptom in older adults, women and people with diabetes.

4. Cold sweat

Sudden clammy sweating, without heat or exertion to explain it, is the body's stress reaction to a heart under attack. Skin may also look pale or ashen.

5. Nausea, vomiting or indigestion-like discomfort

Feeling sick to the stomach, vomiting or a heavy burning in the upper abdomen are often mistaken for acidity or food poisoning. If antacids do not help, if the discomfort is accompanied by sweating or breathlessness, or if you have risk factors, treat it as a possible heart problem.

6. Dizziness, extreme fatigue or a sense of doom

Light-headedness, a sudden weakness, an overwhelming tiredness that is unusual for you, or an inexplicable feeling that something terrible is about to happen can accompany a heart attack. Fainting may occur if the heart rhythm becomes unstable.

Symptoms Vary: Who Needs to Be Extra Careful?

• Women more often have breathlessness, nausea, fatigue, back or jaw pain and may have less typical chest pain.
• People with diabetes may have "silent" heart attacks with minimal pain because of nerve damage.
• Older adults may present with confusion, sudden weakness, falls or breathlessness.
• Younger people may ignore symptoms because they believe they are too young, even though smoking, stress and family history can cause early heart attacks.

Do Not Do This

• Do not wait to see if it passes. If symptoms last more than a few minutes, call for help.
• Do not try to "walk it off," do household chores or go to work.
• Do not drive yourself or ask a relative to drive you through traffic if an ambulance is available.
• Do not take painkillers like diclofenac or ibuprofen or herbal remedies in place of seeking care.
• Do not assume it is gas just because it is in the upper abdomen.
• Do not hide symptoms because you do not want to worry the family.
• Do not delay because of cost or paperwork. Emergency treatment starts first.

What to Do: A Quick Action Plan

1. 1Call an ambulance immediately (112 or the hospital's number).
2. 2Sit down and stay calm. Avoid any exertion.
3. 3Chew aspirin if you are not allergic and have no bleeding problem, while waiting.
4. 4Unlock your door and ask someone to stay with you.
5. 5Have your medicine list and previous reports ready if it takes only a few seconds.
6. 6If you lose consciousness and are not breathing normally, a bystander should start chest compressions and use an AED.

What Happens When You Reach the Hospital

Emergency teams follow a fast pathway.

1. 1Triage and ECG within minutes. An ECG shows whether an artery is completely blocked (an ST-elevation heart attack) or partially blocked.
2. 2Blood tests including troponin to confirm heart muscle damage.
3. 3Immediate medicines: aspirin, other antiplatelet drugs, blood thinners, pain relief, oxygen if needed and others tailored to your condition.
4. 4Reopening the artery: emergency angioplasty (with stenting) is preferred when available within the recommended time. If not, clot-dissolving medicines are given and the patient is transferred to a centre with angioplasty facilities.
5. 5Monitoring in an ICU or coronary care unit for rhythm disturbances, blood pressure and heart function.
6. 6Echocardiography to assess the damage and pumping function.
7. 7Further decisions: bypass surgery may be considered for complex blockages.

Recovery After a Heart Attack

• Hospital stay: usually three to seven days if no complications.
• Medicines: lifelong aspirin and a statin in most patients, plus other medicines such as a second antiplatelet agent, a beta-blocker and an ACE inhibitor or similar drug. Never stop them without advice.
• Cardiac rehabilitation: supervised exercise, education and counselling that reduce the risk of another attack.
• Return to activity: most people return to work in weeks to a few months, depending on the damage and the job. Walking is encouraged early and increased gradually.
• Emotional recovery: anxiety and low mood are common after a heart attack. Talk about them with your doctor, family or a counsellor.
• Lifestyle: quit smoking, eat a heart-healthy diet, exercise, control blood pressure, cholesterol and diabetes, and manage stress.

Preventing a Heart Attack

• Know your risk: check blood pressure, cholesterol and sugar regularly.
• Stop tobacco in all forms.
• Eat a balanced diet low in salt, sugar, trans fats and processed food.
• Exercise at least 150 minutes a week.
• Control weight and waist size.
• Take prescribed medicines consistently.
• Limit alcohol and avoid drugs such as cocaine.
• Manage stress and get enough sleep.
• Know your family history, and tell your doctor about relatives with early heart disease.
• Get regular check-ups after age 30 to 40.

When Symptoms Are Not a Heart Attack

Chest discomfort has many causes, including acid reflux, muscle strain, anxiety, lung conditions and inflammation of the chest wall. The point is not to diagnose yourself, but to let a doctor do it quickly. It is far better to go to hospital and be told it was not your heart than to stay at home and find out too late.

When Symptoms Come and Go: Unstable Angina

Some people have chest discomfort that appears on exertion for a few weeks and then starts to occur with less effort, lasts longer or wakes them at night. This pattern, called unstable angina, means a plaque is becoming unstable and a heart attack may be close. It needs urgent evaluation, not a routine appointment next week. If your usual pattern changes, go to the emergency department the same day.
