Which statement about sudden cardiac death is true?

• A. True: Myocardial infarction or angina always precede sudden cardiac death
• B. False
• C. Only in young athletes
• D. It is never associated with prior chest pain

Answer: (B)

Sudden cardiac death happens when a fatal heart rhythm, usually a ventricular arrhythmia, abruptly stops the heart from pumping effectively. It often occurs in the setting of underlying heart disease or a channelopathy, but the sequence of events leading up to it is not the same for everyone. The idea that myocardial infarction or angina always precede sudden cardiac death isn’t correct. Some cases are triggered by ischemia, but many occur without warning symptoms, or even in people without prior chest pain. It’s also not limited to young athletes; SCD can occur in older adults with coronary disease or other cardiomyopathies, as well as in various non-ischemic conditions. Because the statement about MI or angina always preceding SCD is not universally true, the provided option is false.
