As a healthcare professional with expertise in cardiology, I can provide you with information on the signs of an impending heart attack. It's important to be aware of these signs, as quick action can save lives. Here are the four primary signs to watch out for: 1. Chest Discomfort: This can feel like pressure, tightness, pain, or a squeezing or aching sensation in the chest. It may come and go, or it can be persistent. This discomfort can also radiate to the arms, neck, jaw, or back. 2. Nausea and Indigestion: Some people may experience nausea, indigestion, heartburn, or abdominal pain during a heart attack. This can sometimes be mistaken for indigestion or food poisoning. 3. Shortness of Breath: This can occur with or without chest discomfort and may intensify with even mild exertion. 4. Other Symptoms: Breaking out into a cold sweat, feeling extremely fatigued, or experiencing lightheadedness or sudden dizziness can also be signs of a heart attack. It's important to note that not everyone will experience all of these symptoms, and some may have milder symptoms or even no chest pain at all. Women, older adults, and people with diabetes are more likely to experience atypical symptoms. If you suspect someone is having a heart attack, call emergency services immediately and do not attempt to drive the person to the hospital yourself. read more >>
