The correct answer is  Sudden death, defined as death within 1 hour of onset of symptoms, is usually caused by cardiac disease in middle-aged and elderly patients, but in younger age groups noncardiac causes predominate. There is a bimodal distribution in the population, with the first peak before 6 months of age (sudden infant death syndrome). The most common coronary artery finding is extensive chronic coronary atherosclerosis, although acute syndromes do occur.
