Background The purpose of this investigation was to examine the association between average 1-year home blood pressure and the change in left ventricular mass index (LVMI) and pro-brain natriuretic peptide (BNP) levels. Methods This prospective study was a subgroup analysis of lifestyle intervention using mobile technology in patients with high cardiovascular risk: a pragmatic randomized clinical Trial (LIGHT). In total, 242 patients were stratified into tertiles according to their average 1-year home blood pressure. Results Patients grouped into the tertile 3 (T3) had a lower 1-year mean, SBP and DBP. The T3 group had a 2.1 times higher rate of decrease in pro-BNP and a 1.6 times higher rate of decrease in LVMI compared with T1, compared with the reference group. The area under curve (AUC) value of average 1-year home blood pressure was higher than that of mean SBP or DBP. (AUC, 0.75 vs. AUC, 0.70 vs. AUC, 0.69, respectively). Spearman rank correlation demonstrated that average 1-year home blood pressure had a correlation with Δpro-BNP and ΔLVMI. Conclusion The present study showed that average 1-year home blood pressure may have a significant association with a decrease in LVMI and pro-BNP. Our study appears to be the first to evaluate the association between average 1-year home blood pressure and the change in LVMI and pro-BNP.
