Depression and mortality in elderly hypertensive patients

Depression is common in geriatric patients, and has been linked with increases in cardivascular mortality in some patient populations. These British and Brazilian researches tested whether there was a link between depression and mortality among participants in the Hypertension in the Very Elderly Trial (HYVET). The enrollees completed the Geriatric Depression Score (GDS) at baseline and annually. Cox proportional hazards models examined association between GDS score and stroke, mortality and dementia.

The researchers report: "2,656 HYVET participants completed the GDS. The mean follow-up was 2.1 years. A GDS score =6 was associated with increased risks of all-cause (HR 1.8) and cardiovascular mortality (HR 2.10), all stroke (HR 1.8) and all cardiovascular events (HR 1.6). Risk of incident dementia also tended to be increased (HR 1.28). Each additional GDS point at baseline also gave rise to a significantly increased risk of fatal and non-fatal cardiovascular events, all-cause mortality and dementia."

The researchers concluded: "there was a strong association between baseline depression scores and later fatal and non-fatal cardiovascular endpoints over a mean follow-up of 2 years in a hypertensive very elderly group. The mechanism of this association warrants further study."

This study finds evidence of a link between depression and cardiovascular mortality in elderly hypertensive patients, warranting further study.
