Heart disease continues to be the leading cause of death for both men and women in the United States. In fact, the Centers for Disease Control and Prevention (CDC) reports that heart disease causes 1 in every 5 deaths. Heart disease refers to several different types of heart conditions.

According to the National Heart, Blood, and Lung Institute, each year, cardiac arrest causes 300,000 to 450,000 deaths in the United States. It is more common in older men than women. This condition is fatal if it’s not treated immediately. This means it’s essential to know the signs of cardiac arrest and how to respond to someone experiencing it.
