The researchers found that people who were hospitalized with covid-19 often had damage to body organs, including the lungs and kidneys, and one in eight had inflammatory heart disease (myocarditis). As the pandemic developed, symptoms appeared to persist in some people – a condition known as “long covid”.
Previous studies have revealed that less than a third of patientswho have persistent symptoms after hospitalization with a covid, feels fully recovered after a year. Some experts have warned that a long covid may ultimately lead to a generation affected by disability.
Damage to a number of organs
Researchers are now monitoring the treatment of patients who have been hospitalized with covid-19. They found evidence that he could levy a tax on a number of authorities. In addition, the severity of the persistent symptoms appears to be related to the severity of the course of the disease itself.
“Even healthy and fit individuals can suffer from a serious course of the disease and, in order to prevent it, people should take advantage of vaccination offers“ said Professor Colin Berry of the University of Glasgow, who led the CISCO-19 (Cardiac Imaging in Sars Coronavirus Disease-19) study.
“Our study provides objective evidence of abnormalities within one to two months after covid, and these findings are related to persistent symptoms at that time and the likelihood of persistent health problems a year later.” Berry added.
Examination of hospitalized
In an article published in the journal Nature Medicine, the researchers described the results of 159 people hospitalized with covid between May 2020 and March 2021, at a time when there was no milder variant of the virus called omicron. 28 to 60 days after discharge from the hospital performed a series of images and blood tests, and patients also completed questionnaires.
The results were compared with a control group of 29 people of similar age, gender, ethnicity and cardiovascular risk factors who did not undergo covid. The authors report that, compared with the control group, patients who were hospitalized with covid had several abnormalities, manifested, for example, in the results of imaging examinations of the heart, lungs and kidneys.
Showed that approximately 13%, one in eight, of those hospitalized had inflammatory heart disease (myocarditis), while in the control group it was detected in only one participant. Myocarditis was more likely to occur in healthcare professionals and people with acute kidney damage, as well as people with more severe disease requiring invasive ventilation.
Vaccinations and new drugs have brought relief
“These findings reinforce the importance of the vaccination program and new treatments, which have significantly reduced the number of serious cases of covid-19,” said Andrew Morrow of the Institute of Cardiovascular and Medical Sciences at the University of Glasgow.
The results further show that those who were hospitalized they more often needed outpatient secondary care or have been indicated for symptoms corresponding to long covid. Rehospitalizations and deaths were also much more common in this group.
Betty Raman, a cardiologist and long-time covi specialist who did not take part in the study, said the study provided important insights into the prevalence of clinically assessed myocarditis and its association with long-term symptoms in people hospitalized with a covid at the onset of a pandemic.
At the same time, however, she pointed out that the results did not reflect the current situation, as current variants of the SARS-CoV-2 virus, known as omicron, do not often cause a serious course of the disease.
