The association between blood pressure (BP) defined by the 2017 American College of Cardiology/American Heart Association Hypertension Clinical Practice Guidelines with cardiovascular disease (CVD) and chronic kidney disease in patients with diabetes mellitus remains unclear. This study used the National Health Insurance Database of Korea that has health information of 8 922 940 persons who were screened from 2009 to 2014. We determined the BP status of 490 352 diabetes mellitus: level 1 (systolic <120 mm Hg and diastolic <80 mm Hg), level 2 (systolic 120–129 mm Hg and diastolic <80 mm Hg), level 3 (systolic 130–139 mm Hg or diastolic 80–89 mm Hg), and level 4 (systolic ≥140 mm Hg or diastolic ≥90 mm Hg). Over a mean follow-up of 5 years, 6508 CVD events (1.3%), 14 318 cases of chronic kidney disease development (2.9%), 9094 cerebrovascular events (2.0%), and 1150 CVD mortalities (0.2%) occurred. Compared with people with BP levels 1, the adjusted hazard ratios for CVD in people with BP levels 2, 3, and 4 were 1.07 (95% CI, 0.98–1.16), 1.12 (95% CI, 1.04–1.20), and 1.17 (95% CI, 1.08–1.26), respectively. There were also increased risks of chronic kidney disease (1.18 [95% CI, 1.12–1.24] and 1.22 [95% CI, 1.15–1.29]), cerebrovascular disease (1.21 [95% CI, 1.14–1.29] and 1.52 [95% CI, 1.42–1.63]), and CVD mortality (1.31 [95% CI, 1.09–1.56] and 1.91 [95% CI, 1.58–2.32]) among subjects with BP levels 3 and 4 compared with those with BP level 1. These findings provide evidence supporting the 2017 American College of Cardiology/American Heart Association Hypertension Clinical Practice Guidelines for BP targets in diabetes mellitus patients.
