Prevalence and coincidence of hypertension and orthostatic hypotension in pre- and centenarians and their effect on mortality: preliminary results of Moscow centenarian study
Objective. To estimate the prevalence and impact on mortality of arterial hypertension (HTN) and orthostatic hypotension (OH) in centenarians (95 years and older) in Moscow.Design and methods. The study participants were 82 super-long-livers of Moscow city aged 95 years and older (minimum age of 95 years, maximum 105 years), who underwent a comprehensive geriatric assessment at home by a multidisciplinary team (geriatrician, nurse and social worker). The following prospective observation lasted for three years (36 months).Results. Past medical history of HTN was noted in 78 %. The mean systolic blood pressure (SBP) in the supine position was 151 ± 27,9 mm Hg (100-216 mm Hg), and the diastolic blood pressure (DBP) 74 ± 12,8 mm Hg (44-197 mm Hg). OH was detected in 31 % of 61 long-livers who was able to perform an orthostatic test. The presence of OH was not associated with the higher intake of antihypertensive drugs. Within three years, 44 study participants died. The level of blood pressure (BP), history of HTN, and the presence of OH did not affect mortality (p > 0,05).Conclusions. Centenarians have a wide range of SBP and DBP, high prevalence of HTN and OH. BP level, presence of HTN and OH did not affect mortality over 3 year period. Further investigation is needed to understand better the health status of long-livers and factors affecting the prognosis.
