Recent research from Mass General Brigham highlights that stricter control of blood pressure can be more beneficial than previously thought, even with concerns about overtreatment. This study is published in the Annals of Internal Medicine.
The researchers analyzed data from various sources, including the Systolic Blood Pressure Intervention Trial (SPRINT). They looked at different blood pressure targets set at <120 mm Hg, <130 mm Hg, and <140 mm Hg, examining how these levels might affect long-term health outcomes like heart attacks and strokes.
While the study recognizes that medications for high blood pressure can have side effects, it also assessed these risks. The findings indicated that aiming for a target of <120 mm Hg can prevent more heart-related incidents compared to a <130 mm Hg target. However, this stricter target also increased the chances of negative side effects such as falls and kidney issues, along with higher healthcare costs due to more frequent doctor visits and medication use.
Interestingly, even taking potential measurement errors into account, the <120 mm Hg target still proved cost-effective, costing about $42,000 for each additional quality-adjusted life year gained.
Karen Smith, the lead author of the study, stated, “This study gives patients at high risk for cardiovascular issues more confidence in pursuing a more intensive blood pressure goal. Our findings suggest this lower target can prevent more cardiovascular events and provide good value.” However, she also warned that intensive treatment might not suit everyone and emphasized the importance of patient-clinician discussions to tailor treatment strategies.
This discussion is particularly relevant today. A survey by the American Heart Association found that nearly 50% of adults in the U.S. have high blood pressure. Just last year, the CDC reported that nearly 80% of these individuals are unaware of their condition. This emphasizes the importance of regular check-ups and proper blood pressure management.
