    Abstract:
    In 14 patients with essential hypertension, left ventricular function was assessed echocardiographically before and after 4 and 8 weeks of treatment with the betablocking agent atenolol. Atenolol was given orally in a dose of 100 mg/day. After 4 weeks of treatment systolic blood pressure decreased from 160 to 138 mm Hg(p less than 0.001) and diastolic pressure from 105 to 91 mm Hg(p less than 0.001). Heart rate decreased from 76 to 64 beats/min (p less than 0.05). Systolic shortening of the left ventricular transverse diameter declined from 41 to 36% (p less than 0.01), though in no instance did it fall below the lower limit of normality (30%). After 8 weeks of betablocking therapy, blood pressure and heart rate remained essentially unchanged. Systolic shortening increased slightly but insignificantly to 38%. The left ventricular enddiastolic diameter did not change throughout the study. It is concluded that longterm betablocking therapy is associated with a significant reduction of left ventricular function which improves in the later stage of treatment. Since the diminution of left ventricular function is slight, the induction of left heart decompensation is unlikely, at any rate in patients with initially normal left ventricular function.
