Home BP-guided digital approach to prevent the onset of hypertension and its consequences from prehypertension to severe hypertension. SaMD, software of medical device; CVD, cardiovascular disease
27 million Japanese are hypertensive disease and 89.6% of them are treated with any anti-hypertensive medications. This is the first study utilizing the National Database of Health Insurance Claims and Specific Health Checkups to determine the number and age-adjusted prevalence of hypertensive patients and treated hypertensive patients in Japan.
APTT, which is calculated as the ratio between the square of pulse transit time and the RR interval, has acceptable accuracy in tracking beat-to-beat femoral SBP and could detect substantially decreased femoral SBP.
The very short-term beat-by-beat BPV in the supine position at rest correlates well with nocturnal BPV assessed by ABPM but did not correlate with daytime BPV. Differences in the daytime and nocturnal activity levels may have influenced the difference in association with BPV in the very short resting supine position.
Environmental and behavioral factors are associated with seasonal variation in BP. To prevent cardiovascular events, the management of hypertension while taking seasonal variation into consideration may be important.
