Researchers increasingly find that the effects of infection by SARS-CoV-2 extend to the cardiovascular system.

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.

Covid may have permanently damaged people’s immunity
Covid infections are putting people at higher risk of diabetes, strokes, heart disease and other long-term illnesses – but experts warn it may be decades before the full impact is known.

A spike in N.B. heart and stroke deaths in 2021 cited as COVID’s handiwork
New figures show there was a surge in deaths from heart failure, lung disease and strokes in New Brunswick in 2021, as deaths from COVID-19 were also multiplying.

L’espérance de vie diminue pour une deuxième année d’affilée au Canada
COVID-19 was the fourth leading cause of death, although it caused fewer deaths. More than 14,000 people died in 2021 due to the virus, compared to more than 16,000 deaths the previous year.
However, Statistics Canada notes that COVID-19 has hit younger groups more than in the first year of the pandemic.

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
Comments closedOur 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.

Long Covid symptoms create a greater burden of disability than heart disease or cancer, new study shows
People who survived Covid-19 early in the pandemic, before there were vaccines, continued to be at higher risk for a slew of health problems for up to two years after they got over their initial infections, compared to others who didn’t test positive, a new study finds, and that was especially true if they were hospitalized.
These health problems include heart problems, blood clots, diabetes, neurologic complications, fatigue and difficulties with mental health and have come to be known collectively as long Covid.

Many long-covid symptoms linger even after two years, new study shows
People who endured even mild cases of covid-19 are at heightened risk two years later for lung problems, fatigue, diabetes and certain other health problems typical of long covid, according to a new study that casts fresh light on the virus’s true toll.
The analysis, published Monday in the journal Nature Medicine, is believed to be the first to document the extent to which an array of aftereffects that patients can develop — as part of the diffuse and sometimes debilitating syndrome known as long covid — linger beyond the initial months or year after they survived a coronavirus infection.

COVID-19 boosts risks of health problems 2 years later, giant study of veterans says
“In the 3 months postinfection, people who’d had COVID-19 had higher rates of death and many health conditions including heart failure, diabetes, Alzheimer’s disease, and depression.”

COVID-19 took a toll on heart health and doctors are still grappling with how to help
Heart attack-caused deaths rose during every virus surge. Worse, young people aren’t supposed to have heart attacks but Cheng’s research documented a nearly 30% increase in heart attack deaths among 25- to 44-year-olds in the pandemic’s first two years.

After N.B.’s deadliest year, COVID-related strokes and heart attacks are in the spotlight
Infection control epidemiologist Colin Furness said rising deaths from heart attacks and strokes increasingly appear to be related to damage caused by COVID-19 infections.

“People with repeat infections were twice as likely to die and three times as likely to be hospitalized, have heart problems or experience blood clots than were people who were infected only once. In a surprising twist, vaccination status didn’t seem to have an impact — although other studies show vaccines to be protective. Whether these results hold true for the general population is up for debate. The Veterans Affairs cohort was made up mostly of older white men, which is not representative of the wider population.”
