[Clinical, ergometric and polygraphic evaluation of the effects of metoprolol and labetalol administration in essential arterial hypertension. Comparative study].
The clinical effects, the exercise test answer, the left ventricular function by polygraphyc test after administration at middle term of Metoprolol and Labetalol have been evaluated in 20 patients with moderate and non complicated essential hypertension. The study was a double blind cross-over between Metoprolol and Labetalol (270 mg/die per os). Both drugs induced a reduction of PAOS and PAOD. The exercise test induced in all patients a decrease of PAOS and PAOD, showing an improvement of strain tolerance. The normalization of PEP and non modification of LVET seem to confirm that the treatment with Metoprolol and with Labetalol, neither induces significant modification of left ventricular function.
