People with heart disease are four times more likely to die from coronavirus. This conclusion was made by Chinese doctors, whose study was published in the scientific journal JAMA Cardiology.
Heart and vascular problems were common for every fifth Wuhan resident hospitalized with coronavirus infection COVID-19. In the study, doctors note that such patients tolerated coronavirus much worse than other patients.
As part of the study, Chinese doctors analyzed more than 400 residents of Wuhan who were in one of the clinics in the city between January 20 and February 10, 2020. 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.
In patients with heart disease, the infection almost always went according to a more dangerous scenario than in other people. They used to start experiencing the symptoms of COVID-19 and were 10 times more likely to be victims of the most extreme forms of pneumonia, while similar problems affected about 5% of other patients.
Mortality among patients with heart disease in people with coronavirus infection is about 18%, while in other groups of patients in Wuhan, mortality was not more than 4%. Scientists suggest that the virus can directly affect the muscle cells of the heart – with ACE2 receptors through which SARS-CoV-2 penetrates infected cells. However, to establish the exact dependence, scientists need to conduct new research.
