Medical explanation

A myocardial infarction occurs when blood flow to the heart is blocked.

A pulmonary embolism, on the other hand, happens when a blood clot blocks blood flow in the lungs.

Additionally, according to the Cleveland Clinic, "Coagulopathy happens when there's a problem with how your blood forms clots. Usually, there's an issue with proteins that help with clotting."

The actor's remains were cremated on April 28, reported People.
