By now you are aware of the reports of young athletes and other adults dropping dead from cardiac arrest or strokes.

Former Notre Dame and NFL player Paul Duncan is the latest casualty of sudden cardiac arrhythmia that is causing sudden death in young people with no history of heart disease. He was only 35 years old.

Duncan was out running in DeKalb County, Ga. on July 16 when he suddenly collapsed and died after suffering a cardiac arrest his wife Ellen Duncan shared in a post on Instagram.

"Paul went into cardiac arrest while on a run in our neighborhood," she wrote. "Today he was pronounced brain dead. We will have a medical examination to understand cause of death."

Sudden Adult Death Syndrome (SADS) means an unexplained cardiac arrhythmia that leads to cardiac arrest. An arrhythmia is when the heart beats irregularly causing improper filling of blood in the heart's chambers. Thus causing a sudden decrease in oxygenated blood to the brain and vital organs. Death is imminent.

Doctors aren't sure what is causing SADS among the population of young people.

"There appears to be no evidence whatsoever so far linking Covid-19 vaccines" and SADS, immunologist Satyajit Rath said. The SADS Foundation also issued a statement saying it recommends that SADS patients receive the Covid-19 shot.

Doctors say SADS predates the pandemic and that young people were dropping dead before the pandemic.

But others experts say not so fast.

The head of the Concerned Doctors and Citizens of the Philippines (CDCPh) who goes by the username SuperSally 888 says researchers aren't looking at the right evidence to find a cause.

"In medicine and forensics, if you don't look in the right place, the right way at the evidence, you will not find anything. Young healthy people do not just die unexpectedly, there is always a cause! It just needs to be found."

She goes on to suggest the vaccine-induced spike protein production in the body's cells may be the culprit.

"If heart muscle cells are co-opted to spike protein production, not only is their normal function disrupted, but they will be targeted for destruction by the immune system and ultimately replaced by scar tissue which does not conduct electricity," she said.

She is referring to a node in the heart's upper chamber that acts like a spark plug sending electrical signals to the heart muscle causing it to contract.

Dr. Peter A. McCullough, a world leading cardiologist, says "Prior to 2021, year-on-year population death rates were typically very stable with minimal percent changes over time. Suddenly in 2021 there was mass unprecedented excess mortality in countries concurrent with their vaccine roll-out."

The Internet is still buzzing over the untimely death of YouTube relationship guru Kevin Samuels.

Samuel's mother, Beverly Samuels-Burch, confirmed he died of a cardiac arrest on Thursday morning. Paramedics found him in full cardiac arrest and unresponsive on the floor of his Buckhead apartment.

A cardiac arrest means the heart suddenly stops beating and blood stops flowing to the brain and other vital organs. The person passes out (from lack of oxygenated blood to the brain) and stops breathing.

Brain cells begin dying about 1 minute later if a heartbeat is not restored.

The survival rate for people who experience a cardiac arrest outside of a hospital is less than 10 percent.

A cardiac arrest is usually caused by an irregular or abnormal heartbeat (arrhythmia), underlying medical conditions (such as heart disease), street drugs, prescription medications, smoking, or trauma (gunshot or stab wound).

Most laypeople - even healthcare workers - use the terms "cardiac arrest" and "heart attack" interchangeably. But they are very different.

Approximately 90% of people hospitalized with a heart attack will survive.

A cardiac arrest is usually not survivable without immediate medical intervention.

Those diagnosed with heart disease are at higher risk of suffering a cardiac arrest.

Cardiac arrests can also occur in young people with no signs of heart disease. In fact, cardiac arrest is the leading cause of death among young athletes.

More details have emerged about Kevin Samuels' untimely death at age 56. According to a police report obtained by Phillip Lewis, senior editor of The Huff Post, Samuels suffered a postcoital cardiac arrest in his Atlanta apartment.

According to the police report, a nurse named Ortencia Alcantara called 911 to report a "person injured" on Thursday morning.

Medics arrived to the Residence Buckhead Atlanta apartments to find an unresponsive man, later identified as Samuels.

Alcantara, 32, told police she met Samuels on Wednesday evening and spent the night with him. The next morning, Alcantara said he complained of chest pains before collapsing on top of her.

She moved him to the floor to begin chest compressions while calling 911. She asked the dispatcher to call downstairs to the front desk for a portable defibrillator to restore his heartbeat.

A defibrillator is used to restore a heartbeat to the normal rhythm when the heartbeat is irregular (arrhythmia).

Samuels was transported to Piedmont Hospital where he was pronounced dead.

Samuels' mother, Beverly Samuels-Burch, told NBC News she learned of her son's death through social media.

"That was a terrible thing for social media to put that out," she said in a phone call Friday. "I didn't even know. I hadn't even been notified. All I'm doing is requesting that people pray for us."

The Centers for Disease Control (CDC) is investigating cases of heart inflammation in children and teenagers who got the Covid-19 mRNA vaccine.

Myocarditis is inflammation of the heart muscles, which affects the heart's electrical system that tells the heart to beat regularly.

Myocarditis is usually caused by a virus, such as Covid-19. The symptoms include irregular heart beat, chest pain, fatigue (extreme tiredness), fluid retention (swelling in legs), and shortness of breath.

The CDC says doctors have not established a link between the mRNA vaccines and reports of myocarditis in children who have received the injections.

The CDC urged people to still get vaccinated despite the troubling reports.

Doctors say the condition is "mild" and often goes away on its own.

"Reported cases appear to be mild and often go away without requiring treatment," said CDC spokesman Benjamin Haynes. He said that the reports are "rare given the number of vaccine doses administered."

As of Monday, nearly half of the U.S. population received at least one dose of the mRNA vaccine.
