Pro basketball player who previously blamed COVID vaccine for rare heart condition dies of heart attack
Dominican professional basketball player Óscar Cabrera Adames died this week after an apparent heart attack while possibly undergoing a stress test.
According to a social media post by Dominican sports commentator Héctor Gómez, the 28-year-old’s stress test was performed at a health center in Santo Domingo.

Cabrera Adames reportedly suffered from myocarditis.
The disease can weaken the heart and its electrical system, which decreases the heart’s ability to pump blood, according to the American Heart Association.

After his death, social media posts surfaced in which Cabrera Adames suggested he developed the rare heart condition after receiving two doses of a COVID vaccine.
“I got fucking myocarditis from taking a vaccine. (I received 2 doses of Pfizer) And I knew it! A lot of people warned me,” Cabrera Adames wrote on social media.
He also said the vaccine was a work requirement.
“But guess what? It was mandatory or I couldn’t work. I am an international professional athlete and I play in Spain. I have no health problems, nothing, no hereditary, no asthma, NOTHING! I suddenly collapsed to the ground in the middle of a game and nearly died. I’m still recovering and had 11 different cardiology tests and guess what? They find nothing.
Cabrera Adames’ collapse happened during a Spanish Amateur Basketball League game in 2021. He passed out during the game and was later taken to hospital on a stretcher.
According to the Mayo Clinic, a stress test is designed to show how the heart is working during physical activity. Medical personnel usually attach electrodes to the patient’s chest during the test. A machine then records the electrical activity of the heart.
It remains unclear whether the stress test was the direct cause of Cabrera Adames’ heart attack.
Cabrera Adames was the nephew of Dominican Sports Hall of Fame member Hugo Cabrera.
Cabrera Adames played basketball at Daytona State College in Florida.
In 2016, he was one of 12 men arrested by St. Johns County Sheriff’s Deputies for allegedly attempting to have sex with a minor.
The undercover sting was formed to catch individuals who intended to use the internet as a tool to find children to sexually exploit, law enforcement said at the time.
