NASCAR driver Kyle Busch had bacterial pneumonia for “days to weeks” before he died last week at 41, according to a copy of the death certificate obtained by The Athletic on Wednesday.
Busch’s pneumonia progressed into sepsis, which lasted one day, per the certificate, which listed the pneumonia and sepsis among a “chain of events” that caused Busch’s death. The sepsis led to disseminated intravascular coagulation (DIC), which causes abnormal clotting throughout blood vessels in the body. That ultimately led to hemorrhagic shock, which is caused by severe internal or external bleeding. The DIC and hemorrhagic shock lasted hours, the certificate said.
