Left ventricular (LV) hypertensive modifications are usually classified in 4 different patterns with different prognosis. Increasing in LV mass (LVM) and/or relative wall thickness (RWT) characterize the 4 LV patterns. Normal geometry (NG) is defined by normal LVM and RWT, concentric remodelling (CR) by the increase of only RWT, eccentric hypertrophy (EH) by the increase of only LVM, and concentric hypertrophy (CH) by the increase of both LVM and RWT. Aim. To evaluate the prevalence of these aspects of organ damage in subjects submitted to echocardiography in a hypertension centre echolab. Methods. In two years (2005-2007) we evaluated 1608 consecutive patients submitted to an echocardiography (M 761, F 847, mean age 63.29 years, range 11-93), with assessment of LVM, indexed to body surface area (BSALVM) and to height 2.7 (HLVM), and RWT [(interventricular septum + posterior wall)/end diastolic left ventricular diameter]. Results. Of these subjects, 1108 (68.9%) had a history of hypertension (H) (H mean age 67.46 years, Not H mean age 54.07 years, p125g/ m2 or >49.2g/h 2.7 in men, and >110g/ m2 or >46.7g/ m2.7 in women) and RWT (>0.45) has been observed in 30%, 48.6%, and 46.3% of cases. An increased BSALVM,HLVN and RWT was also observed in 36.6%, 60.5%, and 56.3% of H and in 15.2%, 22.2% and 24% of subjects without H or any other cause of increased wall thickness or LV dimensions (Not H), obviously with significant differences between H and Not H. In the table, the LV patterns in H, Not H and global population (Tot), respect to the two different LVM indexation systems (*=p
