Walter Koenig’s death certificate lists cardiopulmonary arrest as the immediate cause of death, chronic diastolic congestive heart failure as an underlying cause, and acute renal failure as a significant contributing condition, according to reports by the Los Angeles Times and TMZ. Koenig, best known for playing Pavel Chekov in the original Star Trek series, died Oct. 25 at age 90.

What the death certificate reports

The certificate, which the Los Angeles Times said was obtained by TMZ and People, identifies cardiopulmonary arrest as the immediate cause. It lists chronic diastolic congestive heart failure as an underlying cause and acute renal failure as a significant contributing condition. The outlets’ reporting adds detail to the representative’s initial description of Koenig’s death as due to old age.

The listed conditions are recorded as separate parts of the cause-of-death determination. This report summarizes what the certificate states and does not make a broader medical assessment.

Koenig’s Star Trek legacy

Koenig joined Star Trek in its second season as Ensign Pavel Chekov and later reprised the role in seven feature films, according to the Associated Press. His death certificate details are a new follow-up to the widely reported news of his death, rather than a change to the earlier account of when and where he died.
