What is the Difference Between Angina and a Heart Attack?
Heart-related chest pain can be alarming, and it’s important to understand the difference between angina and a heart attack. While both conditions involve discomfort in the chest and relate to the heart’s blood supply, they have key distinctions in severity, cause, and long-term implications.
What is Angina?
Angina is a type of chest pain that occurs when the heart muscle does not receive enough oxygen-rich blood. It is not a heart attack but a warning sign of an underlying heart problem, often coronary artery disease (CAD). Angina can feel like pressure, squeezing, or tightness in the chest, and it may also spread to the shoulders, arms, neck, jaw, or back.
Types of Angina
- Stable Angina – Occurs during physical exertion or stress and improves with rest or medication (such as nitroglycerin).
- Unstable Angina – Occurs unexpectedly, even at rest, and does not improve easily with rest or medication. This condition requires urgent medical attention as it may signal a higher risk of a heart attack.
- Variant (Prinzmetal’s) Angina – A rare type caused by spasms in the coronary arteries, leading to temporary reduced blood flow.
What is a Heart Attack?
A heart attack (myocardial infarction) occurs when blood flow to part of the heart muscle is blocked, usually due to a clot forming in a narrowed artery. Unlike angina, a heart attack causes permanent damage to the heart muscle. Without immediate medical treatment, the affected heart tissue begins to die, which can lead to serious complications or death.
Key Differences Between Angina and a Heart Attack
| Feature | Angina | Heart Attack |
|---|---|---|
| Cause | Temporary reduced blood flow to the heart | Blocked blood flow leading to heart muscle damage |
| Pain Trigger | Often triggered by physical activity or stress | Can occur at rest or suddenly without warning |
| Duration | Typically lasts a few minutes and improves with rest or medication | Lasts longer than a few minutes and does not improve with rest or medication |
| Pain Characteristics | Pressure, tightness, or squeezing | More intense, crushing pain, often with additional symptoms like sweating and nausea |
| Risk | A warning sign of heart disease but does not cause permanent damage | Causes permanent heart damage and requires emergency care |
When to Seek Medical Help
- If chest pain lasts longer than a few minutes, does not improve with rest or medication, or is accompanied by symptoms like shortness of breath, nausea, dizziness, or cold sweats, call emergency services immediately.
- If you have stable angina and notice it worsening, occurring more frequently, or becoming unpredictable, consult your doctor promptly.
Conclusion
Understanding the difference between angina and a heart attack can help you respond appropriately to symptoms and seek timely medical care. While angina is a warning sign of potential heart disease, a heart attack is a life-threatening emergency that requires immediate attention. If you experience any chest discomfort, it’s always best to err on the side of caution and seek medical advice.
