Abstract
Background— Electrocardiographic left ventricular hypertrophy (LVH) predicts cardiovascular morbidity and mortality, and regression of ECG LVH may predict improved prognosis in hypertensive patients. However, uncertainty persists as to how best to regress ECG LVH. Methods and Results— Regression of ECG LVH with losartan versus atenolol therapy was assessed in 9193 hypertensive patients with ECG LVH by Sokolow-Lyon voltage or Cornell voltage-duration product criteria enrolled in the Losartan Intervention For Endpoint Reduction in Hypertension (LIFE) Study. Patients had ECGs at study baseline and after 6 months, 1, 2, 3, 4, and 5 years of blinded losartan-based or atenolol-based therapy. After 6 months’ follow-up, adjusting for baseline ECG LVH levels, baseline and in-treatment systolic and diastolic pressures, and for diuretic therapy, losartan-based therapy was associated with greater regression of both Cornell product (adjusted means, −200 versus −69 mm · ms, P P P Conclusions— After adjusting for baseline and in-treatment blood pressure and baseline severity of ECG LVH, losartan-based antihypertensive therapy resulted in greater regression of ECG LVH by Cornell voltage-duration product and Sokolow-Lyon voltage criteria than did atenolol-based therapy. These findings support the value of angiotensin receptor blockade with losartan for reversing ECG LVH.
