Sudden death has long been a diagnosis. when someone dies suddenly at home it can be very difficult to pinpoint a cause Most are assumed to be cardiac but you usually don’t know for sure. The clinical importance is those who have a relative with sudden death are at higher risk of sudden death themselves.
Sometimes the cause is figured out in retrospect when another family member is diagnosed with a heritable condition. I have 2 friends with vascular ehlers danlos which predisposes to fatal vascular ruptures at a young age. Both had one or more relatives with sudden death syndrome My friends diagnosis has shed light on their relatives deaths.
