A new study shows that people who are hospitalized with Bcorona They may be more likely to develop heart damage, according to the website.medicalxpress“.
Early in the pandemic, several studies indicated that many COVID-19 survivors had heart damage even if they did not have an underlying heart disease and were not sick for hospitalization.
The new study, published Friday in the American Heart Association’s journal Circulation, examined the nature and extent of heart damage and inflammation in most people with COVID-19.
Researchers studied 342 patients with COVID-19 who had high levels of the protein troponin in 25 hospitals in the UK between June 2020 and March 2021. High levels of troponin in blood tests are a strong indicator of acute myocardial injury or heart attack. It is my routine to check troponin levels in people hospitalized with COVID-19.
The participants were compared to two control groups, one with 64 people who were hospitalized with Corona and had normal troponin levels, and a second group of 113 people of the same age, gender and cardiovascular health but without Corona or high troponin levels who had not been in the hospital.
All hospitalized patients underwent an MRI scan within 28 days of discharge, and non-hospitalized participants also received an MRI scan.
The study found that 61% of people hospitalized with corona who had high levels of troponin had heart abnormalities including scarring from a myocardial infarction, also known as a heart attack, or from a microinfarction, and this was nearly Twice as many hospitalized corona participants with normal troponin (36%) and those without corona and those with normal troponin (31%).
But when it came to suspected myocarditis, a rare and sometimes fatal inflammation of the heart muscle caused by a viral infection, the researchers found that the prevalence rate was 6.7% in participants with coronavirus, and elevated troponin, compared to 1.7% in those without. This is much less than what has been observed in previous studies, according to Greenwood, MD, professor of cardiology at the Leeds Institute of Cardiovascular and Diabetes Research in England and a cardiologist at Leeds Teaching Hospitals.
