The impact of intensive blood pressure management on cardiovascular events and mortality rates can vary significantly based on individuals’ educational levels, according to a recent study conducted by researchers at the University of Pittsburgh Schools of the Health Sciences and the University of Texas at Tyler.
Published in the Journal of the American Heart Association, the study delved into data from the Systolic Blood Pressure Intervention Trial (SPRINT), a randomized controlled trial that commenced in 2010. The trial compared the effects of aggressive blood pressure management to standard care, revealing that lowering systolic blood pressure to 120 instead of the previous recommendation of 140 led to a 25% decrease in cardiovascular events and a 27% reduction in mortality rates. These groundbreaking results influenced new clinical guidelines in 2017.
In this study, the researchers focused on analyzing the SPRINT cohort comprising over 9,000 hypertensive adults aged 50 and older. They categorized participants based on their educational attainment levels and compared the outcomes within each subgroup. Surprisingly, the study found that while blood pressure control was consistent across all three educational categories (no college education, some college education to college degree, and beyond college degree), the benefits of intensive systolic blood pressure control were more pronounced in individuals with higher educational attainment.
During the follow-up period, participants with the highest level of education experienced a significant two-fold reduction in cardiovascular risk with intensive blood pressure management. On the other hand, those with lower educational levels did not exhibit the same level of benefit. Dr. Jared W. Magnani, a UPMC cardiologist and associate professor of medicine at Pitt, emphasized the importance of considering social and structural factors beyond medication management in influencing cardiovascular risk.
The results underscore the need for further research into social determinants of health to enhance cardiovascular outcomes, irrespective of individuals’ educational backgrounds. By exploring these unmeasured factors, healthcare providers can tailor interventions to address the unique needs of diverse populations and improve heart health outcomes.

The research was led by Joshua Garfein and his team, shedding light on the nuanced relationship between educational attainment and the impact of blood pressure management on cardiovascular health.
