Quick Answer: Can The Flu Cause Heart Damage?

What organs are affected by influenza?

Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs..

How long can you live with myocarditis?

For example, in many typically healthy adults with uncomplicated coxsackievirus myocarditis, symptoms can start to improve over a couple weeks. In other cases, the heart takes a few months to recover. Sometimes, the damage to the heart muscle is permanent and heart failure persists after the inflammation has resolved.

Can a virus cause heart arrhythmia?

Virus infections can cause cardiac arrhythmia. Scientists have now discovered the molecular mechanism. They have demonstrated that the receptor which the virus uses to infect heart cells is normally necessary for regular heart beat. Likewise, when the receptor is absent, arrhythmia occurs.

Can the flu affect your heart?

Flu is a respiratory illness and because of that, patients can develop problems with appropriate oxygen levels, which can affect every organ in the body, including the heart. It can especially take a toll on the heart if you already have heart problems.

How long does it take for lungs to recover from flu?

Acute bronchitis often develops three to four days after a cold or the flu. It may start with a dry cough, then after a few days the coughing spells may bring up mucus. Most people get over an acute bout of bronchitis in two to three weeks, although the cough can sometimes hang on for four weeks or more.

How long does the flu virus live in your body?

According to the Centers for Disease Control and Prevention (CDC) , an uncomplicated influenza infection will last from three to seven days in most people, including children. However, a cough and feelings of weakness or fatigue can last for two weeks or longer.

Does the flu raise blood pressure?

Viral infections like the flu also put added stress on your body, which can affect your blood pressure, heart rate, and overall heart function. That can raise your odds of having a heart attack or stroke.

Does the flu cause stroke?

Researchers in the first study found that flu can increase your odds for having a stroke by almost 40 percent — and that added risk remains for a full year. “The risk is highest in the 15 days of influenza and starts to decrease as time goes on,” said lead researcher Amelia Boehme.

What kind of virus can cause heart damage?

Viruses. Many viruses are commonly associated with myocarditis, including the viruses that cause the common cold (adenovirus); COVID-19; hepatitis B and C; parvovirus, which causes a mild rash, usually in children (fifth disease); and herpes simplex virus.

Can viral myocarditis go away?

In many cases, myocarditis improves on its own or with treatment, leading to a complete recovery. Myocarditis treatment focuses on the cause and the symptoms, such as heart failure. In mild cases, persons should avoid competitive sports for at least three to six months.

Does Flu weaken immune system?

His results demonstrated that the influenza virus triggers a bodily response that causes a rise in serum glucocorticoid levels, leading to systemic immunosuppression. Such effects render the body vulnerable to bacterial infections that would otherwise be innocuous.

Does influenza cause lung damage?

The flu affects your whole body—including your nose, throat and lungs—and can lead to serious complications in those with chronic illness.

Can the heart repair itself?

But the heart does have some ability to make new muscle and possibly repair itself. The rate of regeneration is so slow, though, that it can’t fix the kind of damage caused by a heart attack. That’s why the rapid healing that follows a heart attack creates scar tissue in place of working muscle tissue.

How does the flu affect the cardiovascular system?

Flu can harm the heart Infections of any kind can affect the heart and circulatory system. Influenza (the flu) is no different. It can make breathing difficult, boost blood pressure, make the heart beat faster, and rev up inflammation. All of these force the heart to work harder.

Can the flu cause myocarditis?

Acute myocarditis is a well-known complication of influenza infection. The frequency of myocardial involvement in influenza infection varies widely, with the clinical severity ranging from asymptomatic to fulminant varieties.

Does flu cause heart inflammation?

In addition, a flu infection causes an inflammatory state in the body, which can also trigger heart attacks by plaque rupture, as this mechanism of heart attacks is associated with inflammation. Even in young, healthy patients without underlying cardiovascular disease, the flu can be deadly.

How long does viral myocarditis last?

Long-term prognosis was usually good with a 3–5-year survival ranging from 56 to 83%, respectively. Patients with acute fulminant myocarditis, once they survive the acute illness, had an excellent long-term prognosis of 93% at 11 years, compared with 45% of the patients presenting with acute non-fulminant myocarditis.

Does heart inflammation go away?

If you are diagnosed with heart inflammation such as endocarditis, myocarditis, or pericarditis, your doctor may recommend medicine or surgery to treat your condition. Mild cases of myocarditis and pericarditis may go away without treatment.

Does heart beat faster when sick?

Also, the sinus node increases the heart rate when the body is stressed because of illness. In all of these circumstances, the heart rate increase is a normal response.
