Answer by Dr_n_ur_friend
Nausea is not a “Classic or most common warning signs of heart attack”.
but Women may experience this less common warning signs of heart attack.
Compared with women, men were significantly more likely to report diaphoresis (profuse perspiration) and significantly less likely to complain of nausea as well as neck, back, or jaw pain.

A recent study, carried out in over 10,000 adults presenting to the emergency departments of 10 hospitals throughout the United States with symptoms suggestive of AMI, found that women were more likely to present with nausea or vomiting, shortness of breath, and clinical findings consistent with heart failure, rather than heart attack.

To understand the mechanism, the physiological aspect of heart attack is related to autonomic nervous system which intiates nauseated symptom.
