What is the first action you should take when you suspect someone is having a heart attack?

When you suspect someone is having a heart attack, the first action you should take is to call 9-1-1. This is crucial because timely medical intervention can significantly increase the chances of survival and reduce the risk of severe damage to the heart. Heart attacks can escalate rapidly, and emergency responders are trained to provide immediate care, which is essential in these situations.

The urgency of calling emergency services allows for professional assessment and treatment, which can include medications or advanced life support that bystanders cannot provide. Access to rapid medical assistance is foundational in managing cardiac events effectively. While other actions such as loosening clothing or administering aspirin are important steps, they should not delay the immediate call for help, which ensures that the patient receives professional medical attention as quickly as possible.
