Predictive Values of Blood Pressure and Arterial Stiffness in Institutionalized Very Aged Population (PARTAGE)
Introduction: High blood pressure especially systolic hypertension is a common condition in the elderly and is considered as a major determinant not only of cardiovascular (CV) morbidity and mortality, but also of several other age-related diseases, frailty and loss of autonomy. Actually, the association between BP levels and morbidity and mortality in the very elderly persons with several co-morbidities remains a controversial issue
Objectives: The aim of the PARTAGE study (Predictive values of blood pressure and arterial stiffness in institutionalized very aged population)is to determine the predictive value of blood pressure (BP) and arterial stiffness for overall mortality, major cardiovascular events and cognitive decline in a large population of institutionalized subjects aged 80 and over.
Methods: The population is composed of 1130 subjects aged over 80, living in nursing home, included by four french university hospitals centre (Nancy, Dijon, Paris, Toulouse) and two Italian (Cesena, Verona). Subjects with severe dementia and a very low level of autonomy are excluded from the study During the first visit, blood pressure were measured using an automatic monitor by physician in sitting and standing position (clinical BP and Orthostatic BP) and by a self measurement of blood pressure 3 measurements, in the morning and the evening, during 3 consecutive days).
Arterial stiffness is evaluated by measuring the carotid-femoral and carotid-radial pulse wave velocity (PWV) with the PulsePen® automatic device. Deaths and cardiovascular events are recorded during a follow-up of 2 years.
The hypothesis of the PARTAGE longitudinal study is that in very elderly frail individuals with multiple co-morbidities, CV risk could be better evaluated by combining self-measurements of BP and direct evaluation of arterial stiffness which are less influenced by the above mentioned disease and co-morbidities.
