Healthy runner’s stroke followed a bad bout of COVID-19

On a ride to high school one morning, Shelley Marshall asked her daughter how things were going with her field hockey team.

At least, that’s what she intended to say. The words came out so garbled that her daughter said, “Mom, what is going on? Are you having a stroke or something? Look at me.”

Marshall looked fine. Although slurred speech is a classic stroke symptom, she didn’t have a droopy face or arm weakness. In a clear voice, she told her daughter not to worry.

Marshall, though, was concerned.

Two days earlier, she noticed that she’d slurred her own name. Her blood pressure had recently been slightly elevated. And she was still recovering from a serious bout of COVID-19, her third. All of this was unusual for Marshall, then 47 and in excellent health, thanks in part to running nearly every day.

Post-COVID ‘heart failure pandemic’ possible: Japan researchers

After contracting COVID-19, patients may have higher risk of heart failure from persistent viral infection in their hearts, even without developing notable heart disease, according to study results announced by Japanese researchers on Dec. 23.

The team including researchers from Riken, Japan’s largest scientific institute, pointed out the possibility of a “heart failure pandemic” in the near future, and is stressing the need for countermeasures.

Why some doctors see COVID as a new risk factor for cardiovascular disease

The severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.

—Dr. Peter Liu, University of Ottawa Heart Institute

High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.

Now some health experts say COVID-19 should be added to that list.

コロナ感染、心不全のリスク高まる可能性 理研など研究

On December 23, a research team from Riken and other institutes announced the results of a study showing that after infection with the novel coronavirus, the heart may be persistently infected with the virus and the risk of heart failure may increase, even if the patient does not develop noticeable heart disease. The team points to the possibility of a sharp increase in the number of heart failure patients in the near future and calls for countermeasures to be taken.

Infection with the novel coronavirus occurs when a protruding “spike protein” on the surface of the virus binds to the ACE2 receptor on the surface of human cells. According to the team, the heart is more likely to express ACE2 compared to other organs. It has also been reported that some people infected with the novel coronavirus have reduced cardiac function, but the detailed mechanism is not known.

Long COVID changes heart rate variability, study suggests

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.

Meta-analysis reveals high rates of heart complications in long-COVID patients

A review and meta-analysis of long-term cardiac complications of long COVID finds a high prevalence of chest pain and abnormal heart rhythms (arrythmias).

Air Pollution Is Really Dangerous, Even More New Evidence Shows

PM2.5 particles are tiny enough to enter the bloodstream and lodge in the lungs, where they contribute to respiratory problems such as asthma. They also can prompt heart attacks and strokes. And they have been linked to diabetes, obesity and dementia and may exacerbate COVID.

The eighth COVID-19 wave is here. Could catching it trigger Alzheimer’s, Parkinson’s or autoimmune disorders?

From the earliest days of the COVID-19 pandemic, scientists have raised concerns about the potential for long-term health problems linked to SARS-CoV-2 and warned repeated infections are likely to increase the risk.

An association between COVID and cardiovascular disease emerged quickly.

And now — almost exactly four years since the first case was discovered in Wuhan — a growing body of scientific research is cautiously linking the inflammation caused by a COVID infection to diseases like Alzheimer’s and Parkinson’s as well as autoimmune conditions from bowel disease to rheumatoid arthritis.

We Interrupt This Mood of Denial to Update COVID’s Threat

Although many Canadians act as though the pandemic has ended, the airborne virus that causes COVID-19 continues to evolve at an amazing pace with devastating consequences for both individuals and the public at large.

How SARS-CoV-2 contributes to heart attacks and strokes

COVID-19 is known to increase the risk of heart attack and stroke. The intense inflammation that occurs throughout the body in severe cases likely contributes to this increased risk. But it’s not clear whether SARS-CoV-2, the virus that causes COVID-19, also affects blood vessels directly.

To find out, an NIH-funded research team, led by Dr. Chiara Giannarelli at New York University School of Medicine, analyzed coronary artery tissue samples from eight people who died of COVID-19 between May 2020 and May 2021. Results appeared in Nature Cardiovascular Research on September 28, 2023.

Debunking COVID-19 myths and misinformation

“The COVID-19 pandemic is over and we are ‘post-pandemic’”

There have been multiple declarations that the pandemic is “over” — perhaps the most well-known was President Joe Biden’s declaration in 2022. When the World Health Organization (WHO) declared COVID-19 to no longer be a global emergency, many misconstrued this to mean the pandemic is “over.” However, what was largely ignored was WHO then explaining COVID-19 continues to be a global threat, continues to kill and disable millions, and variants are still emerging.

SARS-CoV-2 can infect coronary arteries and trigger heart attack, stroke, study suggests

SARS-CoV-2 can directly infect the arteries of the heart, inflaming the fatty plaque inside and raising the risk of heart attack and stroke, suggests a small study published yesterday in Nature Cardiovascular Research.

SARS-CoV-2 infects coronary arteries, increases plaque inflammation

SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findings, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, develop more heart-related complications.

Opinion: Study shows ‘long COVID’ likely to cause mass misery if treatments can’t be developed

Given that 103 million Americans and 770 million people worldwide have been diagnosed as having contracted COVID-19, a future of misery could await a stunningly large cross-section of humanity.

Long COVID still worrisome 2 years after infection

Our findings highlight the substantial cumulative burden of health loss due to long COVID and emphasize the ongoing need for health care for those faced with long COVID. It appears that the effects of long COVID for many will not only impact such patients and their quality of life, but potentially will contribute to a decline in life expectancy and also may impact labor participation, economic productivity, and societal well-being.
