COVID-19 and Your Heart

COVID-19 and Your HeartSARS-CoV-2 is a respiratory virus that causes the COVID-19 disease. It is spread via small droplets from the nose and mouth, and from touching infected surfaces.

As of posting date, we know that at least 80 percent of people who are infected with the virus can have no symptoms, mild symptoms or moderate symptoms, including a fever and cough. The remaining 20 percent may develop more severe cases of coronavirus.


How Does COVID-19 Affect the Heart?

The COVID-19 infection causes a high level of inflammation that triggers an extra strong immune response. This response is more than what is needed for this virus and causes hyper inflammation and blood clots. The blood clots can lead to stroke and heart attacks even in young and healthy people.

COVID -19 contributes to irregular heartbeats, inflammation of the heart (and the lining of the heart), reduced blood flow to the heart, stroke, blood clotting and cardiac death. Some COVID-19 survivors, who were otherwise healthy, have developed blood vessel injuries, blood clots, arrhythmia, heart failure, myocarditis, strokes and heart attacks even without having severe disease or being hospitalized due to the coronavirus.


Who’s at Risk?

Patients with heart disease, heart disease risk factors, diabetes and obesity are at increased risk for severe COVID-19 and related hospitalization and death.


How to Protect Your Health from COVID-19

  2. Get a flu vaccine. Heart disease also increases your risk of getting influenza, which is a deadly virus.
  3. Follow the treatment plan from your cardiologist r.
  4. Don’t put off medical care due to the pandemic. It is important to continue your regular care.

Taking Care of Your Heart Every Day

Making small lifestyle changes can have a big impact on your heart health. Here are heart healthy tips from the National Jewish Health Cardiology Team.

1. Quit smoking

Limit sodium to 2000 mg a day (1500 mg if you have high blood pressure) to decrease blood pressure.
