Prevalence and correlates of multiple organ damage in referred treated hypertensives: data from the ETODH study.

This study, carried out in a large cohort of treated essential hypertensives attending an out-patient hospital hypertension clinic, extends previous observations by showing that a clustering of two or three markers of organ damage (OD) has a higher prevalence than a single organ involvement. These findings call for a systematic evaluation of cardiac and extracardiac OD in treated hypertensive patients referred to a specialist setting.
