Hello, I'm an expert in cardiology with over a decade of experience in diagnosing and treating heart conditions. I'm here to provide you with an accurate and detailed description of what a mini heart attack, also known as a myocardial infarction or heart attack, might feel like. A mini heart attack, or **non-ST elevation myocardial infarction (NSTEMI)**, is less severe than a full-blown heart attack but still requires immediate medical attention. The symptoms can be quite varied and sometimes subtle, which is why it's often called a "silent heart attack". Here are some common signs and symptoms: 1. Chest discomfort: This can feel like pressure, squeezing, fullness, or pain in the center of the chest. The discomfort can be mild and go away and come back, or it can last for a longer period. 2. Upper body discomfort: Pain or discomfort can spread beyond the chest to the shoulders, arms, back, neck, jaw, or stomach. 3. Shortness of breath: This can occur with or without chest discomfort and may be one of the first signs of a heart attack. 4. Nausea or vomiting: These symptoms can sometimes accompany a heart attack, particularly in women. 5. Lightheadedness or dizziness: Feeling faint or dizzy is another possible sign. 6. Cold sweat: Breaking out in a cold sweat can be a sign of a heart attack. 7. Fatigue: Unexplained or unusual fatigue, especially in women, can be a sign. It's important to note that not everyone will experience all of these symptoms, and some people may have a heart attack without any chest pain at all. If you suspect you or someone else is having a heart attack, call emergency services immediately. read more >>
