do all people with heart attacks have sweat

No, not all people with heart attacks experience sweating. Sweating is one possible symptom of a heart attack, but it does not occur in every individual. Other common symptoms include chest pain or discomfort, shortness of breath, lightheadedness or dizziness, nausea or vomiting, and pain or discomfort in the arms, back, jaw, or stomach. It is important to note that symptoms can vary greatly between individuals, and some may not experience any symptoms at all, especially in cases of silent heart attacks. If you suspect you or someone else is having a heart attack, it is crucial to seek immediate medical attention.
