FRIDAY, March 12, 2021 ( News) – Does COVID-19 help? heart Are people with problems, or preexisting heart issues more prone to disease?

The issue remains unclear, a new British study found that people with heart problems have an increased risk of contracting COVID-19.

“In this research, we have found that impaired cardiac structure and function is associated with a higher risk of subsequent COVID-19. This is important because some studies have suggested that COVID-19 can cause structural damage to the heart. However, these studies only use heart scans from people after infection, so they cannot be certain if the impaired heart structure is disturbing COVID-19, “said the study’s lead researcher Zahara Raisi-Estrabag Explained. He is a Clinical Research Training Fellow at Queen Mary University of London.

In their research, London investigators analyzed the medical records of 310 people in the UK Biobank database. It contains the health and genetic information of over half a million people, including a detailed MRI of their hearts and links to COVID-19 test results from Public Health England.

Researchers found that people with heart disease and poor heart function were more likely to test positive for COVID-19 than those suffering from heart problems. This became true due to factors such as age, gender, ethnicity, poverty, diabetes, high blood pressure, high cholesterol, And previous heart attack.

“In our study, we used imaging data obtained prior to COVID-19, and showed that many of these abnormalities are likely and suggest people likely to have COVID-19 as a result of infection,” Raisi-Estabragh said in a university news Told continue. “This is a very important distinction to direct our management of patients with COVID-19.”

But two experts reading on the new study in the United States said the jury may still be out, which comes first, heart trouble or COVID-19.

“Several studies have demonstrated the harmful effects of COVID-19 on the heart,” said Dr. Cardiologist, a cardiologist at Lenox Hill Hospital in New York City. Ashita Dwivedi mentioned. “Cardiovascular complications of COVID-19 include Stop heartbeat, Abnormal heart rhythm, as well as changes in the structure of the heart. “


He added that the new study “raises the question as to what proportion of cardiac abnormalities may be present before infection after COVID-19,” she said. “This acknowledges the fact that people with abnormal heart are more susceptible to COVID-19 infection.”

But Dwivedi said that the study is small and at this point simply raises an important question about COVID and the heart. “Large, long-term studies are warranted to answer this question and increase our understanding of how COVID-19 affects the heart,” she said.

Dr. Michael Goffman directed clinical cardiology at Long Island Jewish Forest Hills Hospital in New York City. He said that because of the study’s design – a look at older data – “the work-cause cannot be inferred or implied.” Other factors may explain the link, Goffman said.

For example, “It is possible that with underlying patients heart disease COVID-19 may have more severe symptoms and therefore may be more likely to be tested for COVID-19.

viral infections Can usually cause swelling “And heart damage, and the high prevalence of COVID-19 may explain the prevalence of heart-related complications,” Goffman said.

“There is currently a lot of uncertainty in the relationship between heart and COVID-19,” said study supervisor Stephen Peterson, professor of cardiology at Queen Mary University. “There is a need to give definitive answers to these questions for further study in different populations and settings.”

The study was published in the journal on 8 March Aged Clinical and Experimental Research.
