What are the warning signs of a heart attack?

Swollen ankles or feet

Unexplained swelling of the extremities can be linked to poor venous return, a sign that the heart is struggling to circulate blood. This symptom can go unnoticed or be mistaken for water retention. However, it should be taken seriously if it recurs.

These signs don't necessarily mean a heart attack is imminent, but they serve as reminders not to neglect your cardiovascular health. Knowing your body better means you're better equipped to react quickly in case of an alert.
