Study Says Congenital Heart Defects May Not Increase Severe Coronavirus Risk

Gerry McElvaney, the senior author of the study, said that this score is easily calculated and can be applied to all hospitalized COVID-19 patients.

The researchers found that patients with a genetic syndrome and adults with advanced disease from their congenital heart defect were more likely to develop moderate to severe symptoms, though an individual's type of congenital heart defect did not impact symptoms severity. "We were reassured by the low number of congenital heart patients who required hospitalization for COVID-19 and the relatively good outcomes of these patients".

About 1% (40,000) of babies born each year in the United States have one or more heart defects.

Two retrospective studies in Blood Advances add evidence for an association between blood type and COVID-19 risk, indicating that people with blood type O could be less susceptible to infection and experience milder disease.

Only 53 congenital heart patients (43 adults and 10 children)-less than 0.8% of patients at Columbia's congenital heart center-presented to their physician with symptoms of SARS-CoV-2 infection from March through June.

As CNN reports, two studies published on Wednesday recommend that individuals with Type O blood are less inclined to get COVID-19, and may likewise have a lower possibility of becoming gravely sick on the off chance that they are contaminated. Scientists from the Royal College of Surgeons in Ireland University have developed a test that can accurately determine who will have severe COVID-19. This means that it's not clear how the relationship between blood type and Covid-19 works and any link may be coincidental.

Findings from an earlier cross-sectional study by Finzi's group, involving more than 100 patients, suggested that the ability of plasma to neutralize the virus decreased significantly between three and six weeks after symptom onset. Around 42 percent of the Danish population has blood type O and another 42 percent have blood type A. Despite equal representation, fewer people with blood type O caught Covid-19; just 38 percent of the people who tested positive were blood type O, while 44 percent were blood type A. Similarly, people with blood type B and AB also received more positive Covid-19 results than expected. "We have yet to define what those risk factors are".
