Professional basketball player Óscar Cabrera Adames died last week at a health center in the Dominican Republic after an apparent heart attack, Fox News reported.

Sports commentator Héctor Gómez first broke the news on Instagram that the 28-year-old Dominican player, who plays in the Spanish professional league, had been undergoing a stress test when he died.

It is unclear, according to reports, whether the stress test — designed to examine heart functioning during physical activity — precipitated the heart attack.

Cabrera Adames previously was hospitalized after collapsing on the court during a December 2021 game. At the time, he blamed his collapse on COVID-19 vaccine-induced myocarditis, posting on social media:

“I got a damn Myocarditis from taking a f—ing vaccine. (I got 2 doses of Pfizer) And I knew it! Many people warned me.”

Cabrera Adames wrote that he was required to get the vaccine in order to continue playing professionally.

“It was compulsory or I couldn’t work. I am an international professional athlete and I am playing in Spain. I have no health problems, nothing, not hereditary, no asthma, NOTHING! I suddenly collapsed to the ground in the middle of a match and almost died. I’m still recovering and I’ve had 11 different cardiology tests done and guess? They find nothing.”

He said doctors told him he could not play for at least five months until his heart inflammation went down.

Research shows the effects of vaccine-induced myocarditis can last much longer than five months.

A fan posted Cabrera Adames’ original post alongside a video of him collapsing on the court in 2021.

Some media outlets, including Newsweek, called allegations that Cabrera Adames’ reported vaccine-induced myocarditis is linked to his heart attack “conspiracy theories.”

Myocarditis is a debilitating cardiac condition. Severe myocarditis can permanently damage the heart muscle, possibly causing heart failure.

The Centers for Disease Control and Prevention (CDC) reports that myocarditis is a serious adverse event that global evidence shows can be caused by the COVID-19 vaccine, particularly among young men.

Cardiologist Peter A. McCullough, M.D., MPH, told The Defender in an email that Cabrera Adames’ death, along with his previously reported myocarditis, was concerning and should be investigated further.

He said:

“I am deeply concerned that his reported symptomatic myocarditis was in 2021 and now he dies on a routine stress test in 2023. This calls for an autopsy and assessment of his vaccine records, prior blood tests, ECGs, echocardiograms, and MRIs for clues to his risks for fatal COVID-19 vaccine-induced myocarditis.”

According to Basketball Insiders:

“Up to this point, we are yet to have an official statement on the cause of Oscar Cabrera Adames’ death. All we know is that myocarditis restricts your heart’s ability to pump blood, and most cases ends in sudden death due to heart failure.”

McCullough tweeted that one reason so many athletes are dying suddenly is because they are unaware they have myocarditis and people with myocarditis should avoid exercise.

The CDC revealed in a May 2021 report it was aware that myocarditis and pericarditis were adverse events associated with the COVID-19 mRNA vaccines, particularly in young men.

But evidence shows the CDC and U.S. Food and Drug Administration (FDA) were aware of myocarditis safety signals as early as Feb. 19, but hid the data from the public until after the FDA granted Emergency Use Authorization and the CDC recommended the vaccination of children ages 12-15.

Professional sports leagues, such as the NFL, started mandating the vaccines in August 2021 — that was after the FDA in June 2021 added a warning about the risk of myocarditis and pericarditis to fact sheets for Moderna and Pfizer following the CDC’s May 2021 report.

Since then, there has been a spike in the number of sudden deaths among athletes. Mercola reported that since March 2021, there was an unprecedented surge in cardiac arrest and other heart issues among elite athletes, citing the fact that 769 athletes collapsed with heart issues on the field during a game between March 2021 and March 2022.

The average age of those athletes who suffered cardiac arrest is just 23 years old.

According to Edward Dowd, a Swiss study documented an average of 29 deaths per year in that demographic prior to 2021. Dowd, a former BlackRock fund manager, is the author of “‘Cause Unknown’: The Epidemic of Sudden Deaths in 2021 and 2022.”
