Cardiovascular impact of long COVID
Often referred to as “long COVID,” this condition is characterized by a variety of recurring symptoms, primary among them being persistent chest pain and heart palpitations that affect daily functioning.
Recent research from the University of Queensland (UQ) has yielded significant insights into the underlying causes of these enduring symptoms.
In a groundbreaking study, researchers aimed to delve deep into the cardiovascular complications associated with long COVID.
“We discovered elevated levels of cytokines, proteins which help control inflammation in the body, in the blood samples of people at about 18 months post-infection with SARS-CoV-2,” explained Professor Kirsty Short.
The study revealed that these cytokines significantly impact the functioning of cardiomyocytes, which are the heart’s muscle cells essential for maintaining its pumping capabilities.
By pinpointing the role of chronic inflammation in cardiovascular manifestations, this research addresses a previously murky aspect of long COVID, especially for those experiencing symptoms well over a year after their initial infection.
Studying long COVID through blood samples
The research team analyzed blood samples from 50 participants across Australia, including individuals suffering from long COVID for over a year.
A unique technology, the “immuno-storm chip” nanotechnology developed at UQ’s Australian Institute for Bioengineering and Nanotechnology (AIBN), was employed to detect trace elevated cytokine levels and assess cardiac tissue damage markers.
“It’s only early days and these results require validation in additional patient cohorts,” cautioned Professor Short.
The study primarily focused on individuals exhibiting cardiovascular symptoms, and while it shows promise, further research is necessary to confirm and expand upon these findings.
A collaborative scientific endeavor
The research is a result of a collaborative effort among multiple institutes, involving experts from varying fields to ensure a comprehensive analysis.
COVID’s lasting impact on heart health
The findings underscore the critical importance of investigating the long-term effects of COVID-19 on cardiovascular health, specifically among those struggling with symptoms over a year after infection.
Identifying elevated cytokine levels presents a potential pathway for developing targeted treatments aimed at reducing inflammation and protecting the heart health of long COVID patients.
Approximately 65 million individuals worldwide are affected by post-acute sequelae of COVID-19 (PASC), many presenting with debilitating cardiovascular symptoms.
Guiding future research
This initial study lays the foundation for further research, emphasizing the need for broader investigations across diverse populations to validate initial findings.
Additionally, future research could focus on whether specific anti-inflammatory therapies can alleviate the persistent cardiovascular symptoms observed in long COVID patients.
The ongoing investigation into chronic inflammation and its implications in long COVID is crucial for developing effective diagnostic tools and treatments.
The study is published in the journal Nature Microbiology.

Alright, ladies and gentlemen, gather ’round! Today, we delve into a rather complicated topic—long COVID! You might think it’s just a clever name for “I still cough from time to time,” but no! It’s like a bizarre sequel to a horror movie that nobody asked for. You recover from the virus, but instead of rolling the credits, you’re left with lingering symptoms. It’s the gift that keeps on giving! Just like my Auntie Edna’s fruitcake; nobody wants it, but it shows up every year.
Anyway, according to recent research from the University of Queensland (or UQ for those in the know, which frankly sounds like a hip coffee shop, doesn’t it?), the main star of the show is something called “cytokines.” No, they’re not a new breed of bacteria from a sci-fi novel, but rather proteins that help control inflammation in the body. Elevated levels of these little guys in the blood of long COVID patients could explain the heart palpitations and chest pain that many endure long after they’ve treated their Netflix binge.
Professor Kirsty Short, who sounds like someone I’d want to invite to a dinner party—so smart yet intriguingly mysterious—has led the charge on this research. She claims that these pesky cytokines are having a direct impact on our heart cells, known as cardiomyocytes. Now, if you’re like me, you’re slightly alarmed by that. I mean, what’s next? My larynx deciding to form a union?
In layman’s terms, the professor tells us that damaging these essential cells leads us to a whole new world of cardiovascular symptoms. It’s a classic case of “you thought you were done, but the plot thickens,” right out of a Twilight Zone episode. And just when you thought the story couldn’t get any stranger, here comes the immune system throwing a tantrum 18 months post-COVID like a drama queen at a wedding!
Now, what’s interesting is they studied the blood from 50 participants from across Australia, including those who were completely unscathed by COVID. Let’s just say if there were any prizes for being lucky, these folks would win a lifetime supply of—what else—Australian beer!
An admirable technological feat was employed in this study; the “immuno-storm chip,” which sounds like a superhero with a penchant for saving the day, but is in actuality a cutting-edge nanotechnology. This is science and medicine flirting—“Can I take you to dinner, or shall we analyze your blood samples first?”—Ah, the romance of modern research!
But caution is the name of the game here; even Professor Short warns that we’re only scratching the surface of this mystery. It’s a bit like a mystery novel where the detective arrives at the scene only to find a half-eaten sandwich and a crying cat. Yes, more studies are needed!
In conclusion, folks, what’s the takeaway? Well, if you think you’ve got long COVID and your cardiovascular system is throwing a mini rave in your chest, it might be time to check in with a healthcare professional. While we eagerly await more research (and hopefully a firm conclusion), let’s raise a glass to science—an ever-evolving field that understands the complexities of our bodies as though they were solving a Rubik’s Cube while riding a roller coaster! Cheers to better health and maybe a little less drama, huh?
