When it comes to a heart attack, time is critical. While these situations may not be common, knowing how to respond can truly make a difference. And beyond emergency care, a few simple daily habits can help protect your heart without stress or drastic changes.

If you suddenly feel unwell: what should you do right away?

A heart attack can strike out of nowhere. If you experience symptoms — or see someone else who might be — here’s what to do:

First, call emergency services right away (in France, dial 15 or 112). Fast medical response is crucial.

Second, try coughing deeply and forcefully while waiting for help. Yes, really. Take a deep breath, then cough hard — like you’re trying to clear your lungs. This may help keep blood and oxygen flowing to your heart and brain until help arrives. It’s not a substitute for treatment, but it might buy you precious time.
