People enrolled in a large clinical hypertension management trial were half as likely to control their blood pressure if they received care at clinics and primary care practices in low-income areas, suggests a study. The study was published in JAHA: Journal of the American Heart Association.

The findings are based on data obtained from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) which compared the effectiveness of three blood pressure lowering drugs. The study used 140/90 mm Hg as the threshold for high blood pressure, while the American Heart Association recognizes high blood pressure as 130/80 mm Hg.

Researchers know that living in low-income areas is associated with higher rates of high blood pressure, heart failure and stroke. The new study explored whether cardiovascular outcomes vary by socioeconomic factors in a randomised clinical trial in which participants are treated equally.

“While medications are the mainstay of hypertension control, there are other factors that we need to pay attention to that are impacting blood pressure control, and the ultimate outcomes we care about – heart disease, stroke, hospitalisation and longevity,” said Erica Spatz, the study’s senior author.

Participants in the low-income areas were more likely to be female, black, Hispanic, have fewer years of education. Participants in low-income areas also surprisingly had fewer cardiovascular risk factors such as history of heart attack or stroke, Type 2 diabetes and cigarette smoking.

Also, participants in the low-income areas visited their doctors less compared to higher-income areas, potentially due to transportation access, social support and health behaviours which may have indirectly impacted some outcomes.

The findings suggest that clinical trial design should consider the socioeconomic context of the treatment site and participants’ neighbourhoods.
