Here Are 8 Possible Warning Signs:

Fatigue

Fatigue affects 70% of women, and if it’s not something you usually experience, it could be a main symptom of an impending heart attack.
Though men can also experience this symptom, it’s more common in women.
This fatigue is often described as extreme, with a lack of energy and motivation—both physically and mentally—that worsens as the day goes on.
Even simple tasks, like making your bed or taking a shower, can feel exhausting.

Abdominal Pain

About 50% of heart attack survivors report abdominal pain. Nausea (on an empty or full stomach), bloating, or stomach aches are common, and these symptoms can affect both men and women.
Before a heart attack, this pain tends to come and go. Physical or emotional stress can make it worse.

Insomnia

Insomnia affects 50% of women and often comes with high anxiety or trouble focusing. Symptoms include trouble falling asleep, staying asleep, or waking up early in the morning.
