Key takeaways:
- Prevalence of hypertension among patients with chronic kidney disease increased from 2011 to 2020.
- Two-thirds of patients with CKD do not meet their blood pressure goal, despite an increase in prescriptions.
PHILADELPHIA — The rate of hypertension among patients with chronic kidney disease has increased. Yet even with more medication being prescribed, most patients are not reaching blood pressure goals, researchers said at ASN Kidney Week.
“Our work is focused on cardiovascular outcomes in chronic kidney disease patients in the U.S.,” Sadaf Akbari, MD, a postdoctoral research fellow at the University of Iowa, told Healio. “Here we wanted to see what happened to blood pressure control among U.S. adults with chronic kidney disease.”
Akbari and colleagues used data from the National Health and Nutrition Examination Survey for the periods 2011 to 2014, 2015 to 2016 and 2017 to 2020. They identified respondents with CKD and sorted them into categories based on systolic BP readings.
Among patients with CKD, 66% reported having hypertension or taking BP medications from 2011 to 2014, compared with 69% from 2015 to 2016 and 86% from 2017 to 2020.
Akbari noted that the portion of patients with CKD who are not taking BP drugs decreased during the timeframe of the study.
The number of patients taking two BP medications doubled from the 2011 to 2014 period to the 2017 to 2020 period, and the number of patients taking three or more medications nearly tripled in the same timeframe.
Despite an increase in medication prescriptions, 17% of patients with CKD had systolic BP of 130 mm HG to 139 mm HG, and 37% had systolic BP of 140 mm Hg or greater from 2017 to 2020.
“No matter which guideline we apply, we still have a large number of the population that haven’t met the guideline goal,” even with prescribing more BP medications, Akbari said.
