- But even those who had mild symptoms were still at risk.
- Heart failure, a long-term condition, occurs when the heart is unable to pump blood around the body properly, usually because it has become weak or stiff.
- Looking at almost 800 Brits, the team found those who had battled Covid had a greater reduction in grey matter thickness and tissue damage in regions of the brain associated with smell.
People who have used Covid are more likely to experience severe and fatal adverse effects as reported by The Sun.
Hospitalisation
Even those who didn’t have an illness severe enough to be hospitalised are at risk, doctors say.
Research, recently published in the journal Nature Medicine but conducted before vaccines were widely available, warned long-term effects could be seen in the heart and vascular system.
These include cardiac arrest, which is when the heart suddenly grinds to a halt.
It needs urgent medical attention, including CPR at the scene.
The study found people who had battled Covid had a 2.5-fold higher risk of cardiac arrest in the year following than those who had not had the bug.
Heart failure risk
The paper said: “These risks and burdens were evident even among individuals who were not hospitalized during the acute phase of the infection.”
Around 45 more people per 1,000 went on to develop any of the 20 conditions, compared to uninfected people.
People who had Covid faced a 72% higher risk of heart failure after 12 months.
Almost all of the veterans studied had not had a single jab when they caught Covid.
“The new arrhythmias, or the abnormal heart rhythms that people experience, are significant as well and can become incredibly handicapping for a lot of patients.”
A string of hugely positive studies shows Omicron is milder than other strains, especially in the vaccinated.
Diabetes risk
It comes after another study found that those that battled the infection are more at risk of a life-threatening condition that already affects five million Brits.
They were 46% more likely to develop type 2 diabetes for the first time in the year following a positive test.
The finding was true even for people who had less severe symptoms, or none at all.
And it’s also seen in children who catch the virus.
The team at Imperial College London also analysed hospital data from five hospitals across North-West London during the peak of Covid-19 in April 2020.
Blood clots
In the meantime, a Swedish study released in April 2022 discovered that persons who receive Covid are more likely to have blood clots in the year and a half afterwards.
Up to three months after infection, there was a risk of DVT, and up to six months later, there was a chance of a blood clot in the lung.
The enormous inflammatory reaction that might occur in some patients is known to increase the risk of blood clots after getting Covid.
Impact on the brain
Covid survivors have also been warned that the brain could be irreversibly harmed by the virus.
The major organ has been shown in dozens of studies to be damaged in even the mildest forms of Covid illness – most recently by the University of Oxford.
Looking at almost 800 Brits, the team found those who had battled Covid had a greater reduction in grey matter thickness and tissue damage in regions of the brain associated with smell.
Professor Gwenaëlle Douaud, a lead author of the study, said the infection had been mild for 96% of the participants.
“A key question for future brain imaging studies is to see if this brain tissue damage resolves over the longer term,” Prof Douaud said.
