As a medical professional, I can provide you with information on the signs and symptoms of a STEMI, which stands for ST-segment elevation myocardial infarction. This is a serious type of heart attack that requires immediate medical attention. Here are the key signs and symptoms to be aware of: Chest pain or discomfort: This is often described as a feeling of pressure, squeezing, fullness, or pain in the center of the chest. It can last for more than a few minutes or come and go. Shortness of breath: This can occur with or without chest pain and may feel like you are unable to catch your breath. Dizziness or light-headedness: Feeling faint or having a sensation of the room spinning can be a sign of a STEMI. Nausea or vomiting: These symptoms can sometimes accompany a heart attack, particularly in women. Diaphoresis (sweatiness): Unexplained sweating beyond what would be expected from the surrounding temperature or physical activity can be a sign of a heart attack. Palpitations: This is an uncomfortable awareness of the heartbeat, which can feel like the heart is pounding, fluttering, or skipping beats. Anxiety or a feeling of impending doom: A sense of dread or extreme anxiety can be associated with a heart attack. It's important to note that not everyone experiences all of these symptoms, and some people may have mild or atypical symptoms. If you or someone else is experiencing any of these symptoms, especially if they are new, worsening, or occur with exertion or emotional stress, it's crucial to seek emergency medical help immediately. read more >>
