Nausea or Vomiting: 

Feeling nauseous or vomiting may be a symptom, particularly in combination with other signs.

Dizziness or Lightheadedness: 

Feeling lightheaded or dizzy, as if you might faint, can occur during a heart attack.

Extreme Fatigue: 

Sudden and extreme fatigue, weakness, or unexplained tiredness can be a warning sign.

It’s important to note that symptoms can vary between individuals, and not everyone experiencing a heart attack will have the same signs. Some people, especially women, may experience atypical symptoms such as discomfort in the jaw, and upper back, or shortness of breath without chest pain.

If you or someone else experiences these symptoms, it’s crucial to call emergency services immediately. Prompt medical attention can significantly improve the chances of survival and reduce damage to the heart muscle. It’s always better to seek medical help and have a professional determine the cause of symptoms, even if they turn out not to be related to a heart attack.
