Scientists Now Find How CPOVID-19 Causes Heart Injury Even in Those Without Heart Issues
According to new studies, COVID-19 can cause heart injury in people without any medical history of heart conditions. A death rate of 10.5% caused by heart injury in COVID-19 patients was reported by the Chinese Center for Disease Control and Prevention (CCDC). Now, experts have warned people with underlying cardiovascular conditions to isolate themselves as much as possible from people who have COVID-19 symptoms.
1COVID-19 can result in death by heart injury
The new coronavirus SARS-CoV-2 which causes COVID-19 has infected millions of people worldwide and has caused countless deaths. It was primarily considered an upper respiratory disease which severely damaged the lungs, but a new study which was published in JAMA Cardiology found that it even damages the heart.
Dr. Mohammad Madjid, MS, the lead author of the study and the assistant professor of cardiology at McGovern Medical School at UTHealth, said: “We know that the cardiac injury risk is there, no matter if you had prior heart disease or not. So, prior heart disease is a risk factor for higher mortality in these patients. Cardiac injury also is a risk factor, but this can happen to people who are free of heart disease”.
2Influenza and SARS also can worsen underlying heart conditions
Existing cardiovascular diseases can be made worse not only by COVID-19 but by other respiratory viral infections like SARS and influenza, as claimed by Dr. Madjid. This could lead to new heart problems in otherwise healthy people.
It has been emphasized by him that more people die of heart problems than respiratory issues like pneumonia during most flu pandemics. As such similar cardiac problems can be expected in severe cases of COVID-19.
Madjid says: “In my experience, I realized that more people actually die of heart disease rather than pneumonia, so that [the study findings] was not a surprise for me — that from China, that myocardial injuries are very much related to death in these patients”.
3COVID-19 is similar to other diseases which cause heart injury in the later stages
Dr. Brian Kolski, an interventional cardiologist with St. Joseph Hospital in Orange, California said: “It’s been seen with lots of viruses. In fact, we’ve most commonly seen it with Epstein-Barr, and we’ve seen it with influenza — so that’s definitely not a new thing. The difference seems to be in the later stages of this disease”.
He added that: “COVID-19 seems to be more of a respiratory picture first and then at the later stages becomes more of a cardiac”.
