Incident Cardiovascular Disease Among Adults With Blood Pressure <140/90 mm Hg

Background: Data from before the 2000s indicate that the majority of incident cardiovascular disease (CVD) events occur among US adults with systolic and diastolic blood pressure (SBP/DBP) ≥140/90 mm Hg. Over the past several decades, BP has declined and hypertension control has improved. Methods: We estimated the percentage of incident CVD events that occur at SBP/DBP Results: Over a mean follow-up of 7.7 years, 2584 participants had incident CVD events. Overall, 63.0% (95% confidence interval [CI], 54.9−71.1) of events occurred in participants with SBP/DBP Conclusions: Although higher BP levels are associated with increased CVD risk, in the modern era, the majority of incident CVD events occur in US adults with SBP/DBP
