Scientists are warning that a new COVID strain will cause a global “heart failure pandemic,” prompting much skepticism.
A new strain known as JN.1 will cause many people to suffer from “reduced cardiac function,” according to the report.
“Japan’s top research institute Riken has now issued a warning in the new report, which states that the ACE2 receptors, which the coronavirus clings to within human cells, are ‘very common’ in the heart,” reports GB News.
“Even though conclusive clinical evidence that persistent SARS-CoV-2 infection is associated with declined cardiac function has not been reported so far, the proof-of-concept study of the possibility of SARS-CoV-2 persistent infection of the heart and the potential risk of opportunistic progression of heart failure should be validated by a three-dimensional human cardiac tissue model which would serve as the alarm bell for a global healthcare risk,” states the report.

Health officials suggested people should be wary of gathering for New Year’s Eve celebrations, warning, yet again, that hospitals would be at risk of being stretched to breaking point.
Despite everything we’ve learned about the association between COVID vaccines and serious heart problems, it appears they’re now trying to re-brand the heart problems as being caused by COVID itself.
Oh well, guess we better take another round of the “100 per cent safe and effective” then!
Once the new booster is rolled out, expect another spate of healthy, professional sports stars suddenly collapsing in the middle of the field as a result of…checks notes… the JN.1 COVID strain.
Respondents on X shockingly weren’t buying it.

RELATED: Long COVID changes heart rate variability, study suggests
Published December 21, 2023
According to a small case-control study today in Scientific Reports, long COVID can affect heart rate variability (HRV) at rest and during deep breathing, adding to the evidence that persistent symptoms of the virus can be associated with cardiac and dysfunction of the autonomic nervous system (dysautonomia). This system regulates involuntary functions like heartbeat, blood pressure, and sweating.
The study, conducted by Brazilian researchers, included 21 patients with long COVID and 20 controls. Long COVID—defined by the authors as new or persistent symptoms experienced 12 or more weeks after infection—has been associated with heart palpitations, orthostatic intolerance (difficulty staying upright), dizziness, and syncope.
Dysautonomia, characterized by dysregulation of HRV, may explain the persistent symptoms observed in Long COVID patients.
“Dysautonomia, characterized by dysregulation of HRV, may explain the persistent symptoms observed in Long COVID patients,” the authors wrote. “There is currently a lack of evidence demonstrating how long these autonomic symptoms persist post infection.”
Mean heart rate higher with long COVID
In the study, long-COVID patients had reduced HRV at rest and during deep breathing, but mean heart rate was significantly higher in the long-COVID group than in controls. The authors observed these differences during a series of tests that measured heart rate during supine positioning and breathing exercises.
“Patients with Long COVID may present with dysautonomia characterized by an imbalance of HRV, which is reflected in the band potencies of 0.15–0.4 Hz 13, and highlights that this dysautonomia could explain the persistent symptoms observed in patients with Long COVID,” said the authors.
The authors said their findings should guide treatments for long-COVID fatigue and dysautonomia. “Our findings provide a rationale for improving fatigability with interventions aimed at improving cardiac and respiratory system autonomic control, through pharmacological and non-pharmacological measures aimed at reducing the cardiovascular risk in these patients,” they wrote.

RELATED: Repeated mRNA vaccines supercharge immune response against COVID-19, study finds
In a recent study published in the journal Nature Immunology, researchers investigated how repeated mRNA vaccinations improve COVID-19 immunity in SARS-CoV-2-naïve and priorly infected individuals. Focusing on the latter cohort, the study evaluated the diversity and concertation in tandem with multiple sequencing analyses of immune cells isolated from the patient’s peripheral blood mononuclear cells. Study findings reveal that sequential vaccination promotes heterogeneous immune cell clonal expansions, with the third mRNA vaccination resulting in almost two times the number of clones as the first vaccination dose. Parallelly, populations of CD8+ T cells substantially increase, thereby better preparing an individual’s immune system to cope with multiple COVID-19 strains. Surprisingly, the presence and severity of COVID-19 infection were directly associated with post-vaccination immunity.

Does infection prevent infection?
First, a disclaimer – under no circumstances are the authors of the publication or the author of this article recommending that you allow yourself to become infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a means of improving your future immunity against the Coronavirus disease 2019 (COVID-19) pandemic. However, a number of previous studies have established the improved anti-COVID-19 capabilities of ‘hybrid immunity.’ Hybrid immunity arises from the combined effects of both a previous COVID-19 infection and vaccination, which have been consistently found to confer better protection than either alone.
Two main mechanisms for this improved observed immunity have been proposed – an increase in the abundance and diversity of virus-specific memory T (Tm) cells and an increased diversity of spike (S) proteins in the Tm cell pool. Hitherto, however, these hypotheses have never been scientifically tested. Understanding the mechanisms underpinning observed immune responses to COVID-19 in hybrid individuals may allow for improved and personalized vaccination regimes, thereby improving global resistance against the pandemic, which has hitherto infected more than 770 million individuals and cost humanity almost 7 million lives.
