Hollywood is reeling after the sudden death of soap opera heartthrob Patrick Muldoon—and now, the official cause is raising even more questions.
The Days of Our Lives and Melrose Place star, who died unexpectedly on April 19, suffered a myocardial infarction—better known as a heart attack—according to his death certificate. But that’s only part of the story. Documents reveal the 57-year-old actor was also battling deeper, underlying conditions, including a pulmonary embolism and hereditary coagulopathy, a genetic disorder that affects how the body forms blood clots.
In simple terms, Muldoon’s body may have been fighting a silent and dangerous internal battle long before his sudden collapse.
The revelation adds a tragic layer to what initially appeared to be a shocking, out-of-nowhere loss. A pulmonary embolism—essentially a blockage in the lungs caused by a blood clot—can be deadly and often strikes without warning. Combined with a clotting disorder, it can create a perfect storm inside the body.
Muldoon, whose remains were cremated on April 28, was still actively working and looking ahead to new projects just days before his death. In fact, the actor shared an upbeat Instagram post only two days earlier, expressing excitement about his involvement in the upcoming crime thriller Kockroach, which stars Chris Hemsworth, Taron Egerton, Zazie Beetz, and Alec Baldwin.
“So excited to be a part of this amazing project,” he wrote—words that now read like a heartbreaking final message.
Fans will forever remember Muldoon as the iconic Austin Reed on Days of Our Lives, a role he first played in the early ‘90s before making a comeback years later. He also made waves as Richard Hart on Melrose Place and appeared in fan-favorite projects like Starship Troopers and Saved by the Bell.
As news of his death spread, tributes poured in from former co-stars and friends who painted a picture of a man far beyond his on-screen persona.
Alison Sweeney, who worked alongside him on Days of Our Lives, called the news “heartbreaking,” remembering Muldoon as “brilliantly talented, endlessly kind and generous in spirit.” She added that he had a unique charm that lit up every set he stepped onto.
Lisa Rinna, who played his on-screen sister, also honored him with an emotional post, sharing a photo of the two with a broken-heart emoji.
Behind the fame and fan-favorite roles, Muldoon leaves behind a grieving family, including his partner Miriam Rothbart, his parents, his sister and brother-in-law, and his niece and nephew.
What makes the loss even more chilling is how quickly everything unfolded. One moment he was celebrating future projects—the next, gone. And now, the details emerging suggest that beneath the surface, a hidden medical condition may have been quietly putting his life at risk.
For fans, it’s a devastating reminder that even those who seem healthy and thriving can be facing battles no one sees.
