Sudden cardiac death (SCD) risk stratification is based on clinically recognized risk factors (RF), such as reduced left ventricular (LV) ejection fraction (EF), heart failure (HF), prior myocardial infarction (MI), and syncope. These RFs fail to capture the majority of SCDs.

Unlike a heart attack, cardiac arrest is an electrical malfunction that causes the heart to stop beating suddenly. Without immediate intervention, sudden cardiac death can occur within minutes. This results in a failure to pump blood to the brain and other vital organs.
