Deaths from previous illnesses with COVID-19?
Certain illnesses can dramatically increase the risk of dying from the consequences of COVID-19, and in some cases even triple it. This discovery could help the public health system to improve the care of sick people and develop interventions specifically targeting these high-risk groups.
Cardiovascular disease, high blood pressure, diabetes, congestive heart failure, chronic kidney disease, stroke and cancer increase the risk of dying from the virus that causes COVID-19, news results show study by researchers at the Penn State College of Medicine. The study was published in the English language journal “PLOS ONE”.
In a systematic review and meta-analysis of studies published from December 2019 to early July 2020, researchers looked at which chronic diseases put people in hospital at risk of dying from COVID-19.
Data from over 65,000 people were assessed
The study evaluated data from over 65,000 people aged 61 on average from 25 studies around the world. The study found, for example, that cardiovascular disease can double the risk of dying from COVID-19. The research group also found that other pre-existing conditions can increase the risk of dying from COVID-19 one and a half to three times.
Some previous illnesses are common
The study suggests that not only are the above chronic diseases common in people with COVID-19, but their presence is a warning sign of a higher risk of death. Unfortunately, the prevalence of cardiovascular disease and high blood pressure is high worldwide.
Eleven diseases have been carefully examined
The team looked at eleven conditions that pose a risk for serious illness and death in COVID-19 patients, including cardiovascular disease, diabetes, high blood pressure, cancer, chronic kidney disease, obstructive pulmonary disease chronic, stroke, congestive heart failure, asthma, chronic disease Liver disease and HIV / AIDS.
How much has the risk increased?
Compared to people hospitalized with COVID-19 without previous illness, the team found that people with diabetes and cancer were 1.5 times more likely to die. People with cardiovascular disease, high blood pressure and congestive heart failure are twice as likely to die, and people with chronic kidney disease are three times more likely to die if they have COVID-19 at the same time time.
Results may be the subject of further research
“Although the healthcare industry has disseminated anecdotal information on the impact of these risk factors on COVID-19 mortality, our systematic review and meta-analysis is the most comprehensive to date in an attempt to quantify risk, ”study author Vernon Chinchilli of Penn State College of Medicine said in a press release. It is to be expected that other research groups will build on this work in the future, adds the expert.
Weaknesses of previous surveys
Researchers said previous studies examining the relationship between existing, pre-existing chronic conditions and COVID-19 mortality had limitations in terms of the number of countries included, the number of studies included and the number of diseases examined. They also stated that these studies had untreated sources of bias which limited the conclusions that could be drawn from them.
Those affected should be vaccinated as a priority
If SARS-COV-2 occurs seasonally in the future, annual vaccination may be necessary. As soon as an effective vaccine is available, high-risk people with these pre-existing conditions should be given priority to avoid high death rates, the researchers say.

Better understanding through further research
While more research is needed to better understand, especially with regard to the effects of race and ethnicity on COVID-19 survival rates, researchers believe the findings may fuel global prevention strategies. and processing. (as)
