TL;DR: The story of the life and times of Toshihiko Umemura and his family in the years leading up to and including his death.
Journal ArticleDOI
Prognosis of "masked" hypertension and "white-coat" hypertension detected by 24-h ambulatory blood pressure monitoring 10-year follow-up from the Ohasama study.
Takayoshi Ohkubo,Masahiro Kikuya,Hirohito Metoki,Kei Asayama,Taku Obara,Junichiro Hashimoto,Kazuhito Totsune,Haruhisa Hoshi,Hiroshi Satoh,Yutaka Imai +9 more
TL;DR: Conventional BP measurements may not identify some individuals at high or low risk, but these people may be identifiable by the use of ambulatory BP.
Journal ArticleDOI
Prognostic Significance for Stroke of a Morning Pressor Surge and a Nocturnal Blood Pressure Decline: The Ohasama Study
Hirohito Metoki,Takayoshi Ohkubo,Masahiro Kikuya,Kei Asayama,Taku Obara,Junichiro Hashimoto,Kazuhito Totsune,Haruhisa Hoshi,Hiroshi Satoh,Yutaka Imai +9 more
TL;DR: The association between stroke risk and the pattern of circadian BP variation was analyzed with a Cox proportional hazards model and there was no significant association between total strokerisk and the nocturnal decline in BP (percentage decline from diurnal level) or between total strokes and the morning pressor surge.
Journal ArticleDOI
Ambulatory blood pressure and 10-year risk of cardiovascular and noncardiovascular mortality: the Ohasama study.
Masahiro Kikuya,Takayoshi Ohkubo,Kei Asayama,Hirohito Metoki,Taku Obara,Shin Saito,Junichiro Hashimoto,Kazuhito Totsune,Haruhisa Hoshi,Hiroshi Satoh,Yutaka Imai +10 more
TL;DR: It is concluded that the relationship between ambulatory systolic blood pressure and cardiovascular mortality is not U-shaped or J-shaped, and that nighttime blood pressure has better prognostic value than daytime blood pressure.
Journal ArticleDOI
Day-by-Day Variability of Blood Pressure and Heart Rate at Home as a Novel Predictor of Prognosis. The Ohasama Study
Masahiro Kikuya,Takayoshi Ohkubo,Hirohito Metoki,Kei Asayama,Azusa Hara,Taku Obara,Ryusuke Inoue,Haruhisa Hoshi,Junichiro Hashimoto,Kazuhito Totsune,Hiroshi Satoh,Yutaka Imai +11 more
TL;DR: Coefficient of variation, defined as within-subject SD divided by level of blood pressure or heart rate, displayed similar prognostic value and made up a simple method of providing useful clinical information for assessing cardiovascular risk.
