Epidemiologic examination of able-bodied population in Far North revealed time-matched averages and confidence intervals for systolic and diastolic blood pressure, pulse rate in newcomers, individuals with normal and high blood pressure. Those results enable to diagnose arterial hypertension by time-related changes in blood pressure during epidemiologic studies.
The authors demonstrate 24 hours' profile of blood pressure for able-bodied healthy population of Far North. The workers and office staffers appeared to have identical blood pressure profiles that are characterized by lower decrease of nightly blood pressure, prevalent morning and two-humped biorhythm.
The relation of 24-hour blood pressure monitoring indices with degree of target-organs damage in 114 non-natives of the Far North who had no previous antihypertensive treatment was studied. It was found out that mean BP influences on developing of chronic forms of vascular brain pathology, microalbuminuria degree correlates with pulse BP level, development of hypertensive retinopathy is associated with excessive variability of day BP.
