How Long Has Sudden Adult Death Syndrome (SADS) Been Around? Are Vaxxines The Cause?

Today’s Medium article will look at when SADS was first around, refuting claims that we are only hearing about this now after Covid-19 vaccines and the associated allegations surrounding Covid vaccination supposedly causing SADS. So without further ado, let’s get into the article.

➡️ How Long Has SADS Been Around?

According to some uninformed people on social media, they’d like you to believe that SADS has only just been around recently due to the uptick in Covid-19 vaccinations, well the reality is the first documented case of SADS or Sudden Arrhythmic Disease Syndrome with QT Syndrome as a symptom, Leipzig, by Meissner in 1856 [1]. Also, SADS conditions include “Long QT Syndrome, Catecholaminergic polymorphic ventricular tachycardia (CPVT), Brugada Syndrome, Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), Short QT Syndrome, and Timothy Syndromes” [1].

➡️ Is Covid-19 Vaccination The Cause?

Absolutely not. Why? We can look at one study from 2012 long before Covid-19 vaccines were even a hypothesis, which makes a very telling quote directly from the study — “A population as large as the United States will experience the sudden cardiac death of a competitive athlete at the average rate of one every three days, often with significant local media coverage heightening public attention.” [1]

If we look at the USA again, a quote from a study published in AERJournal states the following — “An estimated 180000–300000 sudden cardiac deaths (SCD) occur in the US annually.” [2]

As we can see from these two studies, SADS has been around well before the presence of Covid-19 vaccination. These types of deaths will occur nonetheless whether vaccination was present or not.

With the above in mind, we also need to remind ourselves that correlation does not equal causation [3].

💥 Other studies & data

  • In an observational study, 617 registered FIFA players died between 2014 and 2018 from sudden cardiac arrest. That equates to 154 sudden cardiac arrest deaths each year, again well before Covid-19 vaccines existed. [4]

London Ambulance report regarding cardiac arrests:

Cardiac Arrest Annual Report: 2018/19. [5]
10,152 patients suffered an out-of-hospital cardiac arrest between 1st April 2018 to 31st March 2019.

  • 432 were under 35 years old and only 50 survived.
  • That's 8.5 a week.
    That’s 8.5 under 35’s a week.
    That’s 8.5 under 35’s in one week, in one Ambulance trust.

Broken down data:

  • Age: Under 1
    Number of patients: 54
    Male: 51.9% (28)
    Female: 48.1%(26)
    Survived: 6 out of 54
  • Age: 1–8
    Number of patients: 40
    Male: 52.5% (21)
    Female: 47.5% (19)
    Survived: 4 out of 40
  • Age: 9–18
    Number of patients: 56
    Male: 71.4% (40)
    Female: 28.6% (16)
    Survived: 3 out of 56
  • Age: 19–35
    Number of patients: 282
    Male: 73.0% (206)
    Female: 27.0% (76)
    Survived: 37 out of 282

➡️️ Covid Lasting Effects post-infection

There is insurmountable evidence that post-infection from SARS-CoV-2, can cause death month after infection, so the question remains, are all these deaths coming from Covid-19, rather than vaccination? There seems to be causational evidence to suggest so, especially from the studies & articles below:

  • One study has shown COVID-19 can cause death months after infection, such as a 2.83x increased risk of death in mild COVID-19 patients younger than 65 after 1 year [1].
  • A study found an increase in the trend of sudden cardiac death which has been observed starting with the COVID-19 pandemic. [2]
  • An article published on the Nature science website established that heart-disease risk increases rapidly even after a mild COVID-19 case. [3]
  • A table from a study published in the Nature science journal found that Covid-19 increases the risk of a wide range of cardiac events, with the first citation being the table here (see citation number — [4]). The full study here — [5].
  • A study that performed autopsies on the brains of COVID-19 patients who died shortly after infection found all patients had multifocal vascular damage in the brain which was accompanied by widespread endothelial cell activation. [6]
  • Another study found that hospitalised patients who survived at least a week after being discharged were more than twice as likely to die or be admitted to the hospital again within months compared to the general population. [7]
  • Covid-19 is a massive problem, one study looked at how many systems the virus can get into, which organs it can damage via vascular events and other outcomes which may occur. [8]

➡️️ Conclusion
We can derive from the information above, that SADS cases have happened long before Covid-19 and Covid-19-related vaccines. Another explanation for the incidence of SADS is Covid-19, as it can cause all sorts of medical problems months down the line even in a mild case. There is no causal evidence to suggest that SADS cases are vaccine-related.
