  • Covid-19 symptoms tend to be more severe in patients with comorbidities
  • Hypertension is one of the main comorbidities
  • Until recently, it was not known if all persons with hypertension should be worried about developing severe Covid-19

Hypertension is among one of the most common comorbidities causing concern in Covid-19 patients. 

A question faced by medical researchers – and many hypertension sufferers – is whether all patients with hypertension are at risk of developing severe symptoms, should they contract Covid-19.

Until now, there has been a lack of evidence regarding Covid-19 patients with hypertension, which prompted a team of researchers at the Baqiyatallah University of Medical Sciences in Tehran to conduct a study with the goal of establishing factors that may predict the severity of disease in such patients.

Their findings were published in journal BMC.

Hypertension and Covid-19 severity

For the purpose of the study, the researchers analysed the medical profiles of 598 Covid-19 patients. The patients were divided into two groups, based on whether they had a history of hypertension or not.

They were further compared based on their “epidemiologic, clinical, laboratory and radiological features and also clinical outcomes”.

The role of age, diabetes and kidney disease

Of the analysed patients, 176 had hypertension, and researchers noted that in this group there were also many cases of diabetes, kidney disease and cardiovascular disease. This observation raised questions about whether uncontrolled blood pressure by itself is a risk factor developing severe Covid-19 disease.  

“Our novel study reveals predictive factors for developing severe Covid-19 that can be used by physicians to identify high risk hypertensive Covid-19 cases and determine appropriate treatment approach to achieve best possible clinical outcomes,” the researchers stated.

The researchers concluded their paper by stating that although hypertension patients have a higher risk of contracting Covid-19, their outcomes can be determined by using bodyweight, age, chronic kidney disease, diabetes and cardiovascular disease as predictive factors.
