Measurement of evening BP after drinking and measurement of evening BP after bathing were strongly associated with an increased home systolic ME dif, independent of morning and evening home BP levels. Therefore, evening home BP measuring conditions (before or after drinking alcohol and bathing) should be taken into account while evaluating the home systolic ME dif.

We previously reported that a resting heart rate measured at home (home HR) of ≥ 70 beats per minute was a powerful predictor of the risk of cardiovascular disease mortality, and identified factors affecting home HR in the general Japanese population. The present study examines factors affecting home HR in hypertensive patients treated with antihypertensive medications. Home HR was measured using a home blood pressure

The effects and duration of action of bedtime administration of doxazosin 2 mg for 4 weeks on uncontrolled morning home hypertension were investigated. Morning home blood pressure (HBP) was significantly lowered by bedtime administration of doxazosin. Doxazosin significantly lowered evening HBP only in the subgroup of patients with an uncontrolled evening HBP. The evening (E)/morning (M) ratio was greater in patients with an uncontrolled evening HBP than in those with a controlled evening HBP. The results suggest that bedtime administration of doxazosin effectively suppresses morning HBP in uncontrolled morning hypertensives and lowers evening HBP in uncontrolled evening hypertensives.

We previously demonstrated that heart rate (HR) variability obtained by daytime ambulatory monitoring and that of daily home measurement associated differently with cardiovascular mortality risk; cardiovascular mortality was linked with decreased daytime ambulatory HR variability and increased day-by-day home HR variability. The aim of this study was to identify factors contributing to each variability, clarifying possible reasons for their different predictive values. We obtained daytime ambulatory HR and home HR in 538 individuals of a general Japanese population aged ≥55 years. Daytime ambulatory HR variability and day-by-day home HR variability were estimated as a standard deviation measured every 30 min by daytime ambulatory monitoring and day-by-day home measurements once in the morning for 4 weeks, respectively. There was only weak correlation between daytime ambulatory HR variability and day-by-day home HR variability (r = 0.08∼0.14). In a multiple regression model, daytime ambulatory HR variability was associated with daytime ambulatory HR (P < 0.0001), daytime ambulatory blood pressure (BP) variability (P < 0.0001), and male sex (P = 0.003), while negatively associated with daytime ambulatory systolic blood pressure (SBP) (P < 0.0001) and smoking (P = 0.038). Meanwhile, day-by-day home HR variability was positively associated with home HR (P < 0.0001), day-by-day home BP variability (P < 0.0001), and male sex (P = 0.018). Associated factors of daytime ambulatory HR variability and day-by-day home HR variability were different. Our findings suggest that HR variabilities by different intervals of measurements might be mediated by different mechanisms.
