Understanding Sudden Cardiac Arrest

Sudden Cardiac Arrest (SCA) is a leading cause of death that often occurs without warning. It can affect people of any age, background, or level of health, and survival depends on immediate action.

Prepared communities save lives. When bystanders recognize an emergency, begin CPR, and use an AED, outcomes can change dramatically. Education and access make the difference.

Calah Cares exists to help communities understand, prepare for, and respond confidently to cardiac emergencies.

What Is Sudden Cardiac Arrest?

Sudden Cardiac Arrest occurs when the heart unexpectedly stops beating effectively due to an electrical malfunction. Blood flow to the brain and vital organs stops immediately.

It is not the same as a heart attack. A heart attack involves blocked blood flow, while cardiac arrest is an electrical failure of the heart. Without rapid response, loss of consciousness occurs within seconds and survival chances decrease quickly.

Immediate CPR and the use of an Automated External Defibrillator (AED) can restore a life-sustaining rhythm and dramatically increase survival.

Sudden Cardiac Arrest is a leading cause of death, but immediate response can dramatically improve survival.

350,000+ Cardiac Arrests Each Year

More than 350,000 out-of-hospital cardiac arrests occur annually in the United States. Most happen in homes, churches, schools, and community spaces.

Survival Is Time Dependent

Immediate Action Improves Outcomes

Early CPR and access to an AED significantly increase survival rates. Prepared bystanders are often the critical link before emergency services arrive.
