Which is a sign of a heart attack?

A sign of a heart attack can indeed be pain in the stomach. This occurs because the heart and stomach share nerve pathways, leading to referred pain. Individuals experiencing a heart attack might feel discomfort or pain that radiates to the stomach area, which can sometimes be mistaken for digestive issues. This symptom is particularly notable in women, who often exhibit atypical signs of a heart attack compared to men.

The other options, such as persistent coughing, stabbing pain in the eye, and sudden leg cramps, do not directly correlate with heart attack symptoms. While coughing could be associated with other respiratory or cardiac issues, it is not a classic sign of a heart attack. Similarly, stabbing pain in the eye is unrelated to heart functions, and sudden leg cramps are generally connected to musculoskeletal conditions rather than heart issues. Understanding the varied symptoms can help in recognizing a heart attack promptly and seeking appropriate medical help.
