Reduction in left ventricular mass in patients with systemic hypertension treated with enalapril, lisinopril, or fosenopril.

There are still conflicting data as to whether reduction in LV mass is beneficial. In the present study, no deterioration in LV systolic function occurred in patients in whom regression of LV mass was achieved. Impairment in LV compliance has been shown in hypertensive patients, even in the presence of preserved systolic function and normal LV mass. In our study, improvement in diastolic function was observed only in patients whose LV mass decreased, and it was related to reduction in mass and not to a decrease in mean arterial pressure. Therefore, we suggest that because diastolic function is the first activity to deteriorate in hypertensive patients, it may be the first activity to improve, and this improvement may be related to reduction in LV mass with ACE inhibitors.
