| 1 | Orthostatic hypotension,an often-neglected problem in community-dwelling older people:discrepancies between studies and real life显示文摘Orthostatic hypotension (OH)is a common condition in older persons.According to the 2011criteria,OH is defined by a sustained reduction of systolic blood pressure of 20 mmHg or a 10mmHg-fall of diastolic blood pressure,[1] Its prevalence increases with age and according to a recent systematic review the pooled prevalence in community dwelling older people is 22.2%.[2]Although OH is largely explained by concurrent clinical conditions (in particular, hypertension,diabetes,malnutrition,vascular encephalopa- thy,anemia,Parkinson's disease)[3],aging per se determines a series of physiological dysfunctions potentially representing its biological substratum (e.g.,reduction in barore- flex-mediated cardiovascular function,altered salt and water balance at renal level,impaired cardiac diastolic filling).It is also noteworthy that age-related changes in pharmacokinetic and pharmacodynamic mechanisms of drugs (especially in the context of polypharmacy)also increase the risk of OH. | Sarah Damanti Dario Consormi Annalisa Valentini Benedetta Cerasoli Martina Biotto Federica Conti Marta Clerici Pasqualina Iannuzzi Emanuela Manzo Paolo D Rossi Simona Ciccone Matteo Cesari | 2018 | Journal of Geriatric Cardiology2018，15，10： | 2 |
