Background: Although day-by-day home blood pressure (BP) variability (BPV) has been associated with cardiovascular disease (CVD) risk, it remains unclear whether this association differs from season to season. The present study aimed to assess seasonal variation in day-by-day home BP variability and its association with CVD risk. Methods: We analyzed the data from a nationwide, prospective observational study, the J-HOP study (Japan Morning Surge-Home Blood Pressure), in which 14 consecutive days of home BP monitoring were conducted. The values of SD (SD systolic BP [SBP] ), coefficient of variation SBP , and average real variability SBP of home SBP were used as indices of day-by-day home BPV. Results: Among 4231 participants (mean age, 64.9±10.9 years, 46.7% male, 91.5% hypertensives), all 3 day-by-day home BPV indices were lower in summer than winter after adjusting for confounding factors. In winter, SD SBP , coefficient of variation SBP , and average real variability SBP were significantly associated with increased risk of CVD events (coronary artery disease, stroke, heart failure, and aortic dissection; adjusted hazard ratio [95%CI] per 1-SD of SD SBP , 1.26 [1.02–1.54]; coefficient of variation SBP , 1.24 [1.02–1.52]; average real variability SBP , 1.44 [1.17–1.77]). These relationships were also observed in the analysis of quartiles of BPV parameters (adjusted hazard ratio [95%CI] compared to the first quartile, fourth quartile of SD SBP 2.26 [1.06–4.85]; coefficient of variation SBP 2.96 [1.43–6.15]; average real variability SBP 2.73 [1.25–5.93]). In other seasons, however, there were no significant associations between day-by-day home BPV and CVD event risk. Conclusions: Our findings indicate that day-by-day home BPV measured in winter is more strongly associated with future CVD incidence than that measured in other seasons.
