Abstract

Few studies have investigated whether the prognostic power of home blood pressure (BP) for cardiovascular disease (CVD) events differs across subjects with different diabetic status. We used the dataset of the J-HOP (Japan Morning Surge-Home Blood Pressure) study, which enrolled patients having cardiovascular risks to investigate relationships between home BP and CVD events. We classified the patients as having diabetes mellitus (DM), prediabetes or normal glucose metabolism (NGM) as follows: for DM, a self-reported history of physician-diagnosed DM and/or use of DM medication, a fasting plasma glucose ≥126 mg/dL, a casual plasma glucose level ≥200 mg/dL or hemoglobin A1c (HbA1c) ≥6.5% (n = 1034); for prediabetes, HbA1c of 5.7–6.4% (n = 1167), and for NGM, those who remained (n = 2024). CVD outcome was defined as coronary artery disease, stroke or heart failure. During a median 6.2 ± 3.8 years of follow-up, 259 CVD events occurred. Analysis found both prediabetes (Unadjusted Hazard ratio [uHR], 1.43; 95% confidence interval [CI], 1.05–1.95), and DM (uHR, 2.13; 95% CI, 1.59–2.85) as risks of CVD compared to NGM. In DM, patients with a 10-mmHg elevation of office systolic BP (SBP) and morning home SBP had 16% and 14% higher risks for CVD events. In the prediabetes group, only an elevated morning home SBP conferred a risk of CVD events (uHR, 1.15; 95% CI, 1.00–1.31), but this association did not hold for the adjusted model. Like DM, prediabetes should be recognized as a risk for CVD events, albeit weakly. Elevated home BP contributes to increased CVD risk in diabetes. [Figure not available: see fulltext.]
