Corona virus mainly  attack the lungs and heart below are the reasons  why!

The lungs have been the one being mainly  attacked by the  coronavirus but lately doctors have also noticed that the heart is also being attacked by the virus as well.

It is has been discovered that every   1 of  5 patients end up having heart damage because  of the  COVID-19.A small study was carried out in Wuhan China this study was  published  on March 27 .It was discovered that even though some of the patients have previous case of heart conditions, others  on the other hand do not. So could the heart condition be caused by the virus?

Cardiologists said  different scenarios could be taking place: The heart may be having difficult in pumping  blood if the oxygen is not sufficient ; the heart cells may be attacked by the  virus directly and the body will try  to fight the virus, and this could result in the  mobilization of  a storm of immune cells that will end up attacking  the heart.

“The covid-19 is now the only virus  that affects the heart,” said Dr. Mohammad Madjid,who is an assistant professor at McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth). It has been discovered that the risk of having a heart attack is  thought to increase by six if  the  person has been  infected with the flu virus.This was  according to a study  which was published in 2018 in the New England Journal of Medicine. It has also been discovered that during  influenza epidemics, many  patients succumb to heart complications compared  to  pneumonia, according to a finding  published on  March 27 in the journal JAMA Cardiology. If a person has been infected by a virus the infection can disturb the  flow of blood  to the heart, causing  irregular heartbeats and this will lead to a  heart failure, according to the finds.

So it is really not  surprising ” that novel coronavirus which now being referred to as   SARS-CoV-2 can cause  heart damage, it may be happening more frequently in these patients compared to those who are   infected with other viruses,  this was reported by Madjid,who is  the lead author of the review, told Live Science.

The covid-19  might be  attacking the heart directly. Dr. Erin Michos, the associate director of preventive cardiology at Johns Hopkins School of Medicine said we are saying people who have no history of having heart problems end up having heart damage.Heart damage is not  common  in mild cases of the corona virus , however it  tends to happen more often in patients who have serious symptoms and are hospitalized, she said.

Though the virus mainly affects the lungs, it is moving  in the bloodstream; so it is possible for the  virus to attack and  invade  attack  organs besides the lungs, so the  heart is not spared Michos told Live Science.l The heart cells and the  lung cells are both  covered with surface proteins known as angiotensin-converting enzyme 2 (ACE2) — and t hese molecules act  as “passage ” for the virus to gain access to the  cells. However  this enzyme acts more like a  “double-edged sword,” she said. On  one hand, the ACE2 molecule function  as a doorway  for the virus to enter the cell and multiply, but on the other hand, it normally acts as a “protective” function, Michos said “When the muscle of the heart  is damaged  and inflamed by the virus, the heart can no longer function,” she said.

It has been discovered that the novel covid-19 might indirectly cause  damage  to the heart. In this instance the patient’s immune system ends  up “going haywire,” Michos said. This situation has played out in some   patients who were really sick and they had   highly elevated inflammatory markers — or their  proteins showed  high levels of inflammation in the body. This is referred to as a “cytokine storm,” Michos said. Cytokine storms cause  damage to the  organs of the entire the body, inclusive of the heart and liver, she went on to say. It’s however  not  yet clear why some people have such an elevated response compared while  others do not but some people could be  prone to it due to their genetics, she added. We then have some  patients who already have existencing  heart diseases whos risk of   developing severe symptoms of COVID-19  is very high — and their chances of not survivit are high . “Picture it this way , if their heart already have  difficulty working … it won’t be strong enough to fight this challenge ” of not having sufficient oxygen due to the fact that  their lungs are not  working  well. Cardiologists can  identify  if the heart is  damaged by conducting  a blood test using a  protein called troponin. When  the heart cells are injured, you can tell by the leaking of the  troponin into the bloodstream. But “it’s  not always easy to ” to figure out the kind of heart damage a patient is having, Michos said.”We are really witnessing variety of  cardiac involvement,” Michos said. So it is really important to know  “what’s causing the heart damage because the  treatment vary accordingly.”  For instance, if the virus had  invaded  the heart directly, the patient will  need antiviral medications. However if it is the immune system  causing the  damage to the heart  the patient will need immunosuppressants. As of  now, no direct treatments deals with the  COVID-19, and most of the treatment being administered  currently include  supportive care such as providing more Oxygen.

Experts from Australia and New Zealand are  also strongly recommending  people  with hypertension, heart failure and cardiovascular disease who are already on these pills to  keep using them, according to a study  published on April 3 in The Medical Journal of Australia Some  drugs  are currently under going test to see if they can be used  for treating COVID-19, these drugs  include hydroxychloroquine — this is the  drug that President Trump said could be a  game-changer — could actually  cause  damage to the heart those experts said. Now, the main aim is to figure out if there is  a genetic or biochemical reason why  some people are more vulnerable  to heart damage because of  COVID-19 — and to find out as well what drugs can work  best “to protect the heart from damage,” Michos said.
