Sudden cardiac death (SCD) in people outside of a hospital is most commonly caused by coronary artery disease (CAD). This condition often leads to ventricular fibrillation, a severe type of arrhythmia where the heart's ventricles quiver rather than contract properly, which can result in the heart's inability to pump blood effectively and lead to sudden death.

Other potential causes include:

• Cardiomyopathy: Diseases affecting the heart muscle.
• Arrhythmias: Irregular heartbeats, such as ventricular tachycardia.
• Heart Failure: Chronic issues that can exacerbate into sudden cardiac arrest.
• Congenital Heart Disease: Structural heart problems present from birth.

Given the critical nature of this subject, if you or someone else is experiencing symptoms like chest pain, shortness of breath, or fainting, it's crucial to seek immediate medical attention.
