Orthostatic changes in blood pressure and mortality in a nursing home population.

Objective: Hypertension, orthostatic hypotension and orthostatic hypertension (OHT) are highly prevalent in old age. The associations in the very elderly and frail patients between blood pressure, and especially orthostatic changes in blood pressure, and mortality are unclear. We aimed to investigate the relationships between orthostatic changes in blood pressure, blood pressure and mortality in nursing home residents.
