Less than two weeks after the entertainment world learned of Patrick Muldoon’s sudden passing, a newly released death certificate has shed light on the medical conditions that contributed to his untimely death. The document, obtained exclusively by Us Weekly on April 29, confirms that the actor’s immediate cause of death was a myocardial infarction—commonly known as a heart attack—but also lists two serious underlying health problems that likely set the stage for the fatal event.
What the Death Certificate Shows: Immediate and Underlying Causes
The Los Angeles County Department of Public Health’s death certificate lists the following:
- Immediate cause of death: Myocardial infarction (heart attack).
- Underlying conditions: A hereditary coagulopathy disorder and a pulmonary embolism.
Hereditary coagulopathy is a genetic disorder that interferes with the blood’s ability to clot properly. When clotting is impaired, the risk of abnormal clots forming elsewhere in the circulatory system rises dramatically. In Muldoon’s case, a clot traveled to his lungs, causing a pulmonary embolism—a blockage that can strain the heart and trigger a cascade of cardiovascular complications.
Medical experts explain that when a pulmonary embolism occurs, the right side of the heart must work harder to push blood through the blocked artery. This added stress can precipitate a heart attack, especially in individuals with pre‑existing heart disease or clotting abnormalities.

Born on August 19, 1966, Patrick Muldoon built a respectable career in both television and film.

Muldoon later expanded his résumé with roles in the sci‑fi cult classic Starship Troopers and the drama series Melrose Place. He also ventured into production, serving as an executive producer on several independent projects.
According to the death certificate, Muldoon was never married. He maintained a relatively private personal life, though he was known to have dated several high‑profile actresses, including Denise Richards, who publicly mourned his loss.
