Monitoring and treating your blood pressure is an essential health habit that we now know is particularly important during the COVID-19 pandemic. Hypertension is a preventable and treatable condition that when well-controlled, decreases your risk of severe COVID-19 complications. There has never been a more important time to take control of your cardiovascular health! 

High blood pressure, or hypertension, affects 1 in 4 Canadians. As a healthy adult in Canada, your lifetime risk of developing hypertension is 90%. Taking proactive steps to reduce your risk of developing high blood pressure is important, especially if you have a family history of hypertension. If you currently have hypertension, early and effective treatment reduces your risk of a cardiovascular event, like a heart attack or stroke. Maintaining control of your blood pressure can also reduce your risk of developing severe presentations of COVID-19. 

The Connection Between Hypertension and COVID-19 

From the onset of the COVID-19 pandemic, the Public Health Agency of Canada identified those with pre-existing conditions, including hypertension, as higher risk. Untreated hypertensive patients are at the highest risk; therefore, treating your blood pressure is more important than how you do it. Hypertension Canada encourages you to continue taking your ACEI, ARB or other blood pressure medications previously prescribed by your doctor. There is no evidence that one type of blood pressure medication is superior for reducing the risk of severe complications of COVID-19. 

As more data is collected, hypertension continues to be strongly associated with severe presentations of COVID-19. Recent data from over 11 000 patients across eight different countries showed that 42% of patients hospitalized due to COVID-19 had hypertension. Studies also show an independent link between increased mortality rates and hypertension. (Al-Abbasi B, et al., 2020). 

It’s important to acknowledge that if you have hypertension, you are at increased risk of having a severe presentation of COVID-19. While this seems daunting, the good news is that hypertension is treatable! In the same study referenced above, the authors found that patients treated for hypertension have a reduced risk of mortality than those not currently treated. 

Knowing your Numbers 

Due to COVID-19 restrictions, blood pressure monitors at most pharmacies are not available. Routinely monitoring at home is an excellent way to stay on top of your blood pressure. Check out this infographic for the steps to follow to ensure your at-home blood pressure readings are accurate and reliable. 

Remember to use a validated BP device. Hypertension Canada provides a list of recommended devices that have been proven accurate in research studies.

There are many free resources to track and monitor your blood pressure, including our PreCardix® Blood Pressure app. Monitoring your blood pressure regularly (even daily!) is important to ensure that your numbers are well managed during this time.

Controlling Your Blood Pressure

For mild-moderate hypertension, PreCardix® is clinically proven to lower blood pressure safely and effectively in eight weeks or less in almost 90% of study participants. One daily dose of two 600 mg tablets can reduce your blood pressure by several points and contribute to a sense of control, success and, most importantly, the well-being you need to implement other modifiable lifestyle changes! 

Addressing modifiable lifestyle risk factors associated with high blood pressure is necessary at all stages of hypertension. Hypertension Canada encourages healthy habits like; increasing physical activity, weight management, decreasing sodium intake, smoking cessation and stress management. Adding these simple lifestyle changes to your hypertension management plan allows you to take control of your cardiovascular health and reduce your risk of COVID-19 severe complications. 

Information for your Health Care Practitioner

Please share the PreCardix® product monograph with your health care practitioner if you are considering PreCardix® for your hypertension treatment plan. 

The monograph provides detailed product and safety information, including a list of conditions that are not compatible with the use of PreCardix. 

Making Changes to your Hypertension Treatment Plan

Always consult with your healthcare professional before making a change to your

hypertension treatment plan. PreCardix® is not a cure for hypertension. Take PreCardix® daily as directed on the label to maintain its effect. Many factors influence blood pressure health; therefore, it is critical to measure blood pressure using a Hypertension Canada approved device regularly Track your blood pressure using the PreCardix Tracking AppKnow the warning signs of heart attack or stroke.

Do not take PreCardix® if you are pregnant, breastfeeding, have renal artery stenosis, history of angioneurotic edema or shellfish allergy.
