The first question your mind jumps to is the scariest one: is this a heart attack? Angina and a heart attack are related, and they can feel similar, which is exactly why they are so often confused. But they are not the same thing, and knowing the difference, including when chest pain is an emergency, is genuinely important. This is a guide to understanding both. It is not a substitute for medical care, and when in doubt, the safe answer is always to call for help. **The simplest way to tell them apart** Here is the core distinction, in plain terms. **Angina** is a warning. It is chest pain or discomfort caused by the heart muscle temporarily not getting enough oxygen-rich blood, usually because a coronary artery is narrowed. The heart is strained, but it is not being permanently damaged. When the demand eases, the pain typically eases too. **A heart attack** is an injury. It happens when blood flow to part of the heart is suddenly and severely blocked, long enough that the heart muscle in that area begins to die. This is an emergency, and every minute matters. One way to hold it: angina is the heart saying it is struggling. A heart attack is the heart being harmed. Angina is often a signal that the conditions for a heart attack exist, which is why it should never be ignored, even though it is not an emergency in the same way. **What angina usually feels like** Angina often shows up as pressure, tightness, squeezing, or heaviness in the chest. People describe a weight on the chest more often than a sharp stab. It can spread to the shoulders, arms, neck, jaw, or back. The most telling feature of typical angina is its pattern. It often comes on with exertion or stress, climbing stairs, walking uphill, carrying groceries, a wave of strong emotion, and then eases within a few minutes when you rest or, if prescribed, take nitroglycerin. That predictable come-and-go pattern, tied to effort and relieved by rest, is the classic signature of stable angina. **What a heart attack can feel like** A heart attack can share those same sensations, chest pressure, pain radiating to the arm or jaw, but there are warning differences worth knowing. Heart attack pain often does not ease with rest. It may be more intense, last longer than a few minutes, or come on even while you are sitting still. It is frequently joined by other symptoms: shortness of breath, breaking out in a cold sweat, nausea or vomiting, lightheadedness, or a sense of impending doom that people often struggle to put into words. It is critical to know that heart attacks do not always look dramatic. Symptoms can be subtle, and they can differ. Women, older adults, and people with diabetes are more likely to have atypical signs, fatigue, mild discomfort, or symptoms that do not center on classic chest pain at all. This is one reason heart attacks are sometimes missed or dismissed. **When to treat it as an emergency** This is the part that matters most. Call 911 or your local emergency number right away if: Chest pain or pressure is severe, or lasts more than a few minutes. Pain does not go away with rest, or with nitroglycerin if you have been prescribed it. Chest discomfort comes with shortness of breath, cold sweat, nausea, or lightheadedness. Your usual angina suddenly changes, becoming more frequent, more intense, lasting longer, or happening at rest. This is called unstable angina, and it is treated as an emergency. Do not drive yourself. Do not wait to see if it passes. The treatments that save heart muscle work best in the first minutes and hours, and it is always better to be checked and sent home than to wait too long. No one at an emergency room will fault you for coming in. **Why the difference matters beyond the emergency** Once the immediate danger is ruled out, the distinction still matters, because angina is information. Stable angina that keeps occurring is a sign that a part of your heart is not getting the blood flow it needs. It is worth taking seriously, understanding fully, and managing closely with a cardiology team, both to improve daily life and to lower the risk of something more serious down the road. Understanding what your chest pain is, and what it is telling you, is the foundation for every good decision that comes after it.   | **YOUR NEXT READ** **What Is Refractory Angina?
