What to consider:
Difficulty breathing or feeling winded after the slightest exertion.
Shortness of breath, worse when lying down.
Sudden shortness of breath during regular exercise.

3. Fatigue
   Unexplained fatigue can be an early warning sign of blocked arteries, especially in women. If your heart isn’t getting enough oxygen because of blockages, it has to work harder to pump blood, which can make you feel very tired. Fatigue comes on suddenly and lasts throughout the day despite adequate rest.

What to consider:
Feeling of constant fatigue and weakness.
Struggles to perform daily tasks without fatigue.
It’s hard to stay energetic even after getting enough sleep.
