How Does Covid Affect The Heart

Healthcovid Cases Are Rising Among Teens Schools Are Stepping Up To Vaccinate Them

How Does COVID-19 Affect the Heart? | Paul Cremer, MD

Myocarditis is condition that involves inflammation of the heart muscle. Symptoms can include fever and fatigue, as well as shortness of breath and a very specific type of chest pain. Patients tend to say their chest hurts more when they lean forward. The pain tends to abate when they lean back.

When needed, treatment may involve anti-inflammatory drugs, such as ibuprofen, and in some cases, an intravenous medication called IVIG.

Generally, children who have myocarditis will follow up with a cardiologist for about six months to make sure there are no other significant problems. Most cases are generally mild and go away on their own.

Vaccine safety experts are always on the lookout for a range of possible side effects following any new vaccine. Despite the increased number of reported myocarditis cases among young people, Shimabukuro said, no major red flags have been identified.

Still, the higher-than-normal incidence is worthy of further scrutiny. The CDC will hold a meeting of its Advisory Committee on Immunization Practices on June 18 to further look at the evidence and assess the risk of myocarditis following vaccination.

Until definitive links are made, health officials overwhelmingly recommend Covid-19 vaccinations for everyone ages 12 and older.

Heart And Blood Vessels

The lungs may be ground zero for Covid-19 but scientists think it may also invade the circulatory system, getting deep into our veins.

Precisely how the virus attacks the heart and blood vessels remains a mystery, but experts believe infection may cause blood clots, heart attacks and cardiac inflammation as the virus binds to ACE2 receptors on cells lining our blood vessels.

Patients ill in hospital with Covid are showing signs of significant heart and vascular problems, said Prof Shah. Were seeing a significant proportion of patients developing clots in the arteries feeding into the heart.

One study in JAMA Cardiology journal, found that 20 per cent of 416 patients hospitalised in Wuhan with the coronavirus had heart damage.

Increased likelihood of clot formation seems to be one of the features of severe Covid disease, Prof Shah added. Were also seeing patients get clots elsewhere, including the legs and lungs.

This may explain why patients with diabetes and heart disease are at risk of severe illness with Covid-19 as their vascular systems are already under additional strain.

Covid Vaccines And The Heart

Scientists have discovered a link between the Oxford-AstraZeneca vaccine and a rare blood clotting syndrome.

Theres also a link between mRNA COVID vaccines and a rare side effect of heart inflammation . This seems to be most common in males under 30 and after the second vaccine dose.

But this is very rare. Of the 5.6 million Pfizer vaccine doses administered to Australians so far, there have only been 111 cases of suspected heart inflammation reported up to August 1. There have been no reported deaths associated with this vaccine side effect in Australia.

Recovery from this heart inflammation is generally good. The benefits of vaccination against COVID far outweigh the potential risks of these generally mild conditions.

Nevertheless, if you experience any change in symptoms after having a COVID vaccine, including chest pain, an irregular heartbeat, fainting or shortness of breath, you should seek prompt medical attention.

The vast majority of people with heart conditions are safe to get vaccinated. But if you have had myocarditis or pericarditis in the past six months then speak with your doctor or cardiologist.

Is A Heart Attack More Likely After Covid

That depends: Post says that heart attack has several different forms. A type 1 heart attack, caused by a blood clot blocking one of the hearts arteries, is rare during or after COVID-19 infection.

Type 2 heart attacks are more common with COVID-19, she says. This heart attack can be caused by increased stress on the heart, such as a fast heartbeat, low blood oxygen levels or anemia, because the heart muscle isnt getting enough oxygen delivered in the blood in order do this extra work. We have seen this in people with acute coronavirus disease, but it is less common in those who have survived the illness.

Blood tests have shown that during COVID-19, some people have elevated levels of a substance called troponin in their blood, along with EKG changes and chest pain. Elevated troponin levels are a sign of damaged heart tissue. Sometimes this is from a heart attack. This is less commonly seen after COVID-19.

During acute COVID-19, elevated troponin levels with an abnormal EKG are linked to higher mortality, but not in patients with a normal EKG, Post says.

Dont Delay Getting Your Heart Checked

The Medical Minute: What research tells us about COVID

Many people have been reluctant to seek medical attention amid the pandemic. This includes for both urgent and routine care of heart disease. Longer delays between the onset of the symptoms and hospital treatment are being reported in countries including England, Italy and China. This makes long-term heart damage more likely.

One study found global hospital admissions for heart attacks have decreased between 40% and 50%. An Australian study found a 21% reduction in cardiac surgery at Sydneys Royal Prince Alfred Hospital between March and June 2020.

Its important you dont neglect your heart health even amid the pandemic. If you ever think youre having a heart attack, call triple zero immediately.

What Can I Do To Protect Myself From Heart Complications Of Covid

There are many simple steps you can take to reduce your risk of having heart complications after COVID-19:

  • First and foremost, reduce your chances of becoming ill with COVID-19: This can be done by getting vaccinated and practicing social-distancing measures, like wearing a mask, washing your hands, keeping distance between yourself and others , and limiting travel.
  • If you already have heart disease, check in regularly with your healthcare provider: Because of the pandemic, many people with heart disease have missed out on routine health visits. If you are not comfortable going to the office and you are due for a check-up, ask your provider whether they offer telemedicine visits.
  • Work with your physician to check for and treat any heart risk factors, such as diabetes, high cholesterol, and high blood pressure.
  • Start or keep up with healthy lifestyle changes: Several lifestyle changes can help your heart stay healthy. These include eating a balanced diet, making exercise a part of your daily life, losing weight or maintaining a healthy weight, and cutting out smoking.
  • You Might Have Low Blood Pressure

    How does COVID-19 affect the heart?

    Myocarditis, or inflammation of the heart muscle, is a potentially dangerous effect of COVID-19. “Myocarditis can result from direct heart invasion by the virus itself, or more commonly by inflammation caused by cytokine storm,” wrote Dara K. Lee Lewis of Harvard Medical School earlier this month. “When this occurs, the heart may become enlarged and weakened, leading to low blood pressure and fluid in the lungs.”

    What Other Heart Problems Can Covid

    In addition to increasing the risk of heart attacks, COVID-19 can affect the heart in other ways. The virus can directly infect the heart and blood vessels. It can also cause high levels of inflammation all over the body as the immune system tries to fight off the virus. These factors, in combination with decreased oxygen levels, can create a perfect storm for heart problems, including:

    • Abnormal heart rhythms, also called arrhythmias: Affect the efficiency of the heart to pump blood to the body
    • Heart muscle inflammation, also called myocarditis: Causes chest pain, shortness of breath, and heart muscle weakness in severe cases
    • Stress cardiomyopathy: Heart muscle weakness that is usually temporary, caused by extreme stress on the body, such as an infection
    • Heart failure: A condition in which the heart has a reduced ability to pump blood to the body and lungs
    • Cardiac arrest: When the heart goes into a dangerous heart rhythm, which can cause the heart to stop, leading to death

    What About Heart Problems In Children After Covid

    In general, children who get sick with the coronavirus do not have serious problems as often as adults do. But a very rare complication of COVID-19 called multisystem inflammatory syndrome in children, or MIS-C, can cause serious heart damage, cardiogenic shock or death.

    Children who survive MIS-C can be left with abnormal heart rhythms and stiffened heart muscle that prevents the heart from relaxing normally and beating properly. MIS-C has some similar characteristics to Kawasaki disease.

    Risk Much Higher For Preexisting Heart Conditions

    That study, conducted from January to February, used data from 416 adults confirmed to have COVID-19 and hospitalized at Renmin Hospital of Wuhan University in China.

    Cardiac injury was defined by elevated levels of a protein called troponin, which is measured in the blood. However, Gudimetla explains that detecting abnormal troponins in a critically ill patient with COVID-19 isnt likely to alter management of the patient.

    Without a vaccine for a cure from the infection, only aggressive, supportive care can be rendered, such as maintenance of blood pressure, treating heart failure with drugs, treating secondary infections, support of renal function, and support of respiratory status, which can require ventilators, he said.

    The findings also show that there was a much higher death rate among patients with cardiac injury compared with those without cardiac injury: 51 percent of the patients with existing cardiac injury died versus only 4.5 percent of those without.

    Revealed: How Coronavirus Attacks Your Veins Heart Brain And Blood As Well As Lungs


    Research suggests the contagion can get deep into our vascular system and even our brains so how does the virus attack?

    We think of Covid-19 as a respiratory virus one that simply attacks the lungs.

    But scientists are now wondering if it is much more than that, with a stream of medical papers being published over the last few weeks which suggests the contagion can get deep into our vascular system and even our brains.

    We are seeing a range of illness some people develop blood clots, others heart attacks or kidney failure, said Prof Ajay Shah, BHF Professor and consultant cardiologist at King’s College Hospital, London.

    There are still many unknowns, but the amount of research effort that is going on to try and understand exactly what is happening to patients with Covid is absolutely phenomenal.

    So how does the virus attack?

    Is Heart Damage Caused By Covid

    Post says that if symptoms are due to a cardiac cause, recovery depends on the severity of injury. Very few people have a severe heart attack, such as an acute myocardial infarction, or MI, due to COVID-19, she says.

    Still, heart imaging can reveal minor changes in the heart muscle of some COVID-19 survivors. Post notes that some studies on athletes recovering from the coronavirus have shown some scarring, but stresses that some of these studies did not compare these results with those who had not had COVID-19. How long these minor changes persist and how they affect heart health are not yet known. Experts are developing protocols and recommendations for which athletes should get cardiac testing before returning to play.

    COVID-19 can also affect the strength of the heart pumping, Post says, but subtle abnormalities in heart pumping are not likely to cause people problems.

    A person recovering from COVID-19 may benefit from physical therapy, breathing exercises, and most of all, time. Post advises anyone recovering from COVID-19 should expect a gradual course of recovery, and should not expect a rapid return to their normal activity levels.

    Should I Be Concerned About Thrombosis After Vaccination What Are The Warning Signs

    Thrombosis is an abnormal clot formation that cause stroke, heart attack and other major issues. COVID-19 is associated with a very high risk of thrombosis, therefore a high risk of death.

    In some very rare instances, an abnormal immune response has been associated with the COVID-19 vaccine. In those cases, the number of platelets your body manufactures goes down and a clot forms. This is very rare less than 1 in 50,000 cases, seen primarily in individuals receiving the AstraZeneca COVID-19 vaccine. This vaccine is currently not in use in the United States.

    If you experience severe headache, trouble seeing, loss of strength or balance, chest pain or discomfort, nausea or vomiting in the days following your COVID-19 vaccination, it would be prudent to seek medical attention to exclude this or other rare complications of the COVID-19 vaccine.

    Does Long Haul Covid Cause Heart Problems

    At least 10% of people who get COVID can have symptoms for more than 4 weeks. This condition is called long COVID or long-haul COVID. Many people with long COVID report lingering cardiac symptoms, such as:

    • Chest pain

    POTS is an abnormal increase in heart rate when a person stands up from a lying position, which can lead to:

    • Dizziness
    • Exercise intolerance
    • Fatigue

    Because long COVID is so new, data is still being collected on people dealing with this condition.

    How Can A Respiratory Illness Like Covid

    How does COVID-19 affect the heart?

    Michos explains that cells in the lung and heart are both covered with protein molecules called angiotensin-converting enzyme 2, or ACE-2. The ACE-2 protein is the doorway that the new coronavirus uses to enter cells and multiply.

    ACE-2 normally plays a favorable role in protecting tissue by being anti-inflammatory. But if the new coronavirus somehow disables those molecules, these cells may be left unprotected when the immune system springs into action.

    There are multiple mechanisms for heart damage in COVID-19, and not everyone is the same, Michos says. Temporary or lasting damage to heart tissue can be due to several factors:

    Lack of oxygen. As the virus causes inflammation and fluid to fill up the air sacs in the lungs, less oxygen can reach the bloodstream. The heart has to work harder to pump blood through the body, which can be dangerous in people with pre-existing heart disease. The heart can fail from overwork, or insufficient oxygen can cause cell death and tissue damage in the heart and other organs.

    Myocarditis: inflammation of the heart. The coronavirus may infect and damage the hearts muscle tissue directly, as is possible with other viral infections, including some strains of the flu. The heart may also become damaged and inflamed indirectly by the bodys own immune system response.

    Cytokine Storm: A Serious Coronavirus Complication

    Most serious of all, Michos says, is the possibility of the immune system launching an attack on the invading virus that is so severe that it destroys healthy tissues.

    When responding to infection with the new coronavirus, the body releases a flood of proteins called cytokines that help cells communicate with one another and fight the invaders.

    In some people, perhaps due to a genetic difference, this normal defensive event is exaggerated, leaving them vulnerable to a cytokine storm. In a cytokine storm, the immune system response causes inflammation that can overwhelm the body, destroying healthy tissue and damaging organs such as the kidneys, liver and heart.

    A cytokine storm and its resulting heart damage can also affect the hearts rhythm. Serious ventricular arrhythmias due to a cytokine storm can be catastrophic, Michos says.

    A cytokine storm is difficult to survive. Current research is exploring the possible benefit of using immune-suppressing drugs to treat patients with COVID-19 who experience this serious complication.

    What About The Delta Variant Do The Vaccines Protect Against Delta

    Like all viruses, the virus causing COVID-19 mutates frequently. These variants may differ in their ability to infect, trigger an immune response and induce illness.

    The delta variant is one of the more recent strains of the virus causing COVID-19. It is even more contagious than earlier strains, causing a new surge in cases especially among the young.

    Whether our current COVID-19 vaccines can sufficiently protect against the delta variant has been a concern. However, the current data are reassuring. We strongly advise you to get one of the available COVID-19 vaccines.
