People with heart conditions are more likely to face severe symptoms from COVID-19. What can they do to stay extra safe during this time?

COVID-19 weighs heavily on everyone’s minds – but for people with underlying heart conditions, the situation may be especially worrying.

According to the American Heart Association, people with heart disease, including high blood pressure and congenital heart defects, are more likely to develop more severe symptoms and complications when infected with COVID-19.

If you, or a loved one, are living with a heart condition, here’s what you should know and what you can do.

How does COVID-19 affect the heart?

When the COVID-19 virus enters the body, it primarily targets the respiratory tract and the lungs. When the lungs are infected, oxygen supply to the heart is diminished, placing a huge stress on the heart. For someone with heart disease, where the heart may already have problems with pumping efficiently, this could increase the chances of a heart attack or heart failure.

The COVID-19 virus can also directly infect the heart muscles, causing inflammation and swelling of the heart muscles, heart muscle injury, or trigger off arrhythmias.

Patients with severe COVID-19 infection also appear to have a higher tendency to have blood clots form within the blood vessels. This can increase the risk of a heart attack or stroke.

Furthermore, someone with a heart condition might also have a weaker immune system, making it harder for them to fight off the virus. This means that if they get infected, the virus is more likely to stay longer and cause complications.

How can you stay safe as a heart disease patient?

COVID stay safe
You’ve probably heard this many times, but practising safe distancing and good personal hygiene is our best defence against the virus. If you have a heart condition, this is especially critical! Always follow these golden rules:

  • Wash your hands frequently with soap and water for 20 seconds each time
  • Stay home as much as possible
  • When you have to leave the house, wear a mask and keep at least a 1m away from other people
  • Avoid touching any part of your face without first washing your hands
  • See a doctor immediately if you feel unwell

In addition to the above, heart patients can protect themselves better with these tips:

  • Stay in close contact with your healthcare providers, and find out if online consultations are available
  • Ensure you have a sufficient supply of your prescribed medications, and find out if your healthcare provider can deliver refills
  • Keep handy a list of support contacts – such as relatives, friends and neighbours – whom you can call on for help if needed
  • Stay connected with family and friends through voice or video calls
  • Ensure that your vaccinations, such as Influenza and Pneumococcal vaccines, are up-to-date
  • When buying groceries, check ingredient labels and pick heart-healthy choices, such as lower sodium options

What are the ways to keep your heart healthy?

Staying safe and healthy doesn’t stop at taking precautions against COVID-19. There are everyday lifestyle changes you can make to strengthen your heart and lower your risk of a heart attack or stroke. Here are some important heart-healthy habits to adopt:

  • Eat a heart-healthy diet that includes foods rich in omega-3 fatty acids, such as salmon and mackerel, as well as lots of fruits and vegetables
  • Limit salt, sugar, processed and red meats, trans fats and cholesterol in your diet
  • Get moderate to vigorous exercise for at least 2.5 hours a week
  • Don’t stay seated for too long at a time – get up regularly for a little walk!
  • Find time each day to unwind and relax
