US, WASHINGTON (ORDO NEWS) — Chinese doctors found that the presence of severe problems with the heart and blood vessels increases the risk of death from coronavirus infection by more than four times. Their findings were published by the scientific journal JAMA Cardiology.
“We found that there was a statistically significant association between cardiovascular disorders and mortality among patients suffering from coronavirus infection (COVID-19). Heart problems and blood vessels were characteristic for every fifth patient in Wuhan, which may explain the high mortality rate during hospitalization,” the scientists write.
According to statistics from the World Health Organization (WHO), heart and vascular diseases, including heart attacks, strokes and chronic heart failure, now remain one of the leading causes of death in the world. Each year, about 17 million people die from them, and most of them have similar problems due to hypertension, a consistently high pressure in the blood vessels.
After the outbreak of a new type of coronavirus began in the Chinese city of Wuhan, local doctors noticed that people who suffered from senile or congenital heart and vascular diseases suffered a coronavirus infection much harder than other patients.
Guided by these observations, scientists from Wuhan University tracked how often people with heart and vascular diseases died, as well as their healthy peers who do not have such chronic health problems.
Heart and virus
Doctors analyzed the medical history of more than 400 residents of Wuhan who were in one of the city’s clinics between January 20 and February 10 of this year. All these patients received the same treatment and level of care, which made it possible to understand how strongly cardiovascular diseases affect the development of COVID-19.
These observations showed that carriers of such problems viral infection was much more likely to go according to a more dangerous scenario than other patients. In particular, they used to start experiencing symptoms of the disease and were ten times more likely to become victims of the most extreme forms of pneumonia, while similar problems affected about 5% of other patients.
In general, these differences led to the fact that carriers of chronic heart and vascular problems on average died from coronavirus infection about 4.5 times more often than other carriers of the virus. In general, about half of the first group of patients died from infection, while only 4% of the remaining infected died from a new type of coronavirus (SARS-CoV-2).
Why is this so, scientists can not yet say. However, they suggest that the virus can directly interact with the muscle cells of the heart, since there are ACE2 receptors on their surface through which SARS-CoV-2 penetrates infected cells. All this, as doctors emphasize, should be taken into account when hospitalizing patients with suspected coronavirus infection, their diagnosis and treatment.
