Associations of Systolic Blood Pressure and Diastolic Blood Pressure With the Incidence of Coronary Artery Disease or Cerebrovascular Disease According to Glucose Status
Research Design and Methods: Examined was a nationwide claims database from 2008 – 2016 on 593,196 individuals. Cox proportional hazards model identified risks of CAD and CVD events among 5 levels of SBP and DBP.
Results: During the study period 2,240 CAD and 3,207 CVD events occurred. Compared with SBP ≤119 mmHg, which was the lowest quintile of SBP, hazard ratios (HRs) (95% confidence interval) for CAD/CVD in the 4 higher quintiles (120-129, 130-139, 140-149, ≥150 mmHg) gradually increased from 2.10 (1.73 to 2.56)/ 1.46 (1.27 to 1.68) in quintile 2 to 3.21 (2.37 to 4.34)/4.76 (3.94 to 5.75) in quintile 5 for normoglycemia; from 1.39 (1.14 to 1.69)/1.70 (1.44 to 2.10) in quintile 2 to 2.52 (1.95 to 3.26)/4.12 (3.38 to 5.02) in quintile 5 for borderline glycemia; and from 1.50 (1.19 to 1.90)/1.72 (1.31 to 2.26) in quintile 2 to 2.52 (1.95 to 3.26)/3.54 (2.66 to 4.70) in quintile 5 for diabetes. A similar trend was observed for DBP across 4 quintiles (75-79, 80-84, 85-89, ≥90 mmHg) compared with ≤74 mmHg, which was the lowest quintile.
Conclusions: Results indicated that cardiovascular risks gradually increased with increases in SBP and DBP regardless of the presence of and degree of a glucose abnormality. Further interventional trials are required to apply findings from this cohort study to clinical practice.
