Cardiac workload during exercise under metoclopramide treatment / Presión sanguinea del paciente cardiaco durante el ejercicio y bajo un tratamiento con metoclopramida

RESUMEN

Cardiac workload was determined in normotensive and hypertensive subjects during submaximal treadmil exercise under metoclopramide treatment at the José Gregorio Hernández Hospital and at the Vargas Hospital, Caracas, Venezuela. Subjects were submitted to treadmil exercise during a 30 min period of 5 por ciento glucose solution administration (before and after metoclopramide) and during a 30 min period of metoclopramide, 7.5 µg/Kg/min administration. Treadmill exercise induced an increase of cardiac Workload in both normotensive and hypertensive subjects. Metoclopramide induced a decrease of cardiac workload in normotensives and less in hypertensives. We conclude that metoclopramide, a known DA2 dopaminergic blocker, reduces cardiac workload during keadmill exercise in normotensive and hypertensive subjects:
