Background Left ventricular hypertrophy (LVH), as well as the geometry pattern of the left ventricle, is believed to be an independent risk factor for hypertension. The present study investigated the changes in left ventricular mass, diastolic function and geometry in hypertensive patients in a prospective 5-year follow-up in conjunction with an evaluation of the regularity and effectiveness of treatment. Methods and Results One hundred hypertensive patients older than 18 years were examined according to the study protocol, which included registration of weight, height, vital signs, and echocardiography. After 5 years a repeat examination was performed. Patients were divided into 3 groups according to blood pressure (BP) control : group 1 (n=32), no regular medication; group 2 (n=44), regular treatment but no target BP levels; group 3 (n=14), regular effective treatment. In group 1 an increase in LVH and worsening of diastolic function were observed; in group 2 LVH and isovolumetric relaxation time remained unchanged, while the early peak velocity/atrial peak velocity ratio decreased; in group 3 there was a significant decrease in LVH. The geometry pattern only changed in 21 (23%) patients. Conclusions LVH can be successfully reversed in only hypertensive with adequate BP control. The remodeling pattern appears to be a stable characteristic of the patient and transformation of one pattern into another is infrequent.
