Excessive Sweating

Unusual or excessive sweating can be an early sign of a heart attack. It may happen day or night and is often mistaken for hot flashes or night sweats, especially in women.
Sweating is sometimes described as flu-like, with clammy skin or sweat that appears without exertion or a hot environment. Night sweats may even soak your sheets.

Chest Pain

Chest pain can vary in intensity and form for men and women.
For men, it’s one of the main warning signs of an impending heart attack and should never be ignored. For women, it appears in about 30% of cases.
The pain might radiate to your arms (especially the left), jaw, neck, shoulders, or stomach. It can be constant or come and go.

Always pay close attention to your body and seek immediate medical advice if you notice any of these signs—acting early can save your life.
