The Losartan Intervention For Endpoint (LIFE) reduction in hypertension stu
dy is a double-blind, prospective, parallel group study designed to compare
the effects of losartan with those of atenolol on the reduction of cardiov
ascular morbidity and mortality. A total of 9194 patients with hypertension
and ECG left ventricular hypertrophy (LVH) by Cornell voltage-duration pro
duct and/or Sokolow-Lyon voltage criteria were enrolled in the study, with
baseline clinical and ECG data available in 8785 patients (54% women; mean
age, 67 +/- 7 years). ECG LVH by Cornell voltage-duration product criteria
was present in 5791 patients (65.9%) and by Sokolow-Lyon voltage in 2025 pa
tients (23.1%), Compared with patients without ECG LVH by Cornell voltage-d
uration product criteria, patients with ECG LVH by this method were:older;
more obese; more likely to be female, white, and to have never smoked; more
likely to be diabetic and have angina; and had slightly higher systolic, d
iastolic, and pulse blood pressures. In contrast, patients with ECG LVH by
Sokolow-Lyon criteria were slightly younger; less obese; more likely to be
male, black, and current smokers; less likely to have diabetes; more likely
to have angina and a history of cerebrovascular disease; and had higher sy
stolic and pulse blood pressure but slightly lower diastolic blood pressure
than patients without ECG LVH by this method. By use of multivariate logis
tic regression analyses, presence of ECG LVH by Cornell voltage-duration pr
oduct criteria was predominantly associated with higher body mass index, in
creased age, and female gender, whereas presence of ECG LVH by Sokolow-Lyon
voltage criteria was predominantly related to lower body mass index, male
gender, and black racer: Thus, hypertensive patients who meet Cornell produ
ct and Sokolow-Lyon voltage criteria are associated with different, but pot
entially equally adverse, risk factor profiles.
