ABSTRACT

Estudios animales y ensayos clínicos han demostrado que el daño cerebrovascular agudo puede alterar la función cardiovascular y autonómica produciendo incremento en la incidencia de arritmias cardíacas, hipertensión arterial, daño miocárdico e incremento en los niveles plasmáticos de catecolaminas. Se ha evidenciado que ciertas partes de los hemisfarios cerebrales ejercen influencia clara en el control autonómico del corazón. El presente trabajo de investigación se realizó para tratar de determinar si las alteraciones electrocardiográficas y ecocardiográficas, así como las influencias de la presión arterial que se presentan en pacientes con ACV agudo, se correlacionan con la localización imagenológica obtenida por TAC Cerebral. Se estudiaron 71 pacientes, 33 con ACV en HDC y 38 HCI. Los trastornos del ritmo encontrados fueron: fibrilación auricular 12,7 por ciento, taquicardia supraventricular 9,8 por ciento, extrasístoles ventriculares 14 por ciento, extrasístoles auriculares 9,8 por ciento y branicardia sinusal 4,2 por ciento. De acuerdo al hemisferio en donde sucedió el ACV, la TSV y las extrasístoles ventriculares unifocales fueron más frecuentes en el izquierdo, mientras que bradicadia sinusal fue significativamente más frecuente en el ACV derecho. La TA fue mayor en pacientes con ACV en el lado derecho. Los ACV en HCI se relacionan con taquiarritmias y presión arterial elevadas a diferencia de los ACV en HDC relacionadas con bradiarritmias y disminución de la presión arterial

ABSTRACT

The effects of metoclopramide, labetalol and metoclopramide plus labetalol treatment on baseline cardiovascular parameters and isometric handgrip induced changes, were evaluated in eleven hypertensive subjects. Although all treatments were effective in reducing resting systolic (SBP) and diastolic (DBP) blood pressures, the combination of metoclopramide and labetalol appeared to provide a greater decrease (changes in SBP/DBP: 15/11 mmHg, p<0.05; from 149 + 4/95 +4 mmHg to 134 + 5/84 ñ 3 mmHg) than did labetalol alone (changes in SBP/DBP: 10/9 mmHg p<0.05; from 149 ñ 4/95 ñ 4 to 139 ñ 486 ñ 3 mmHg). At 2 minutes, handgrip increased blood pressure on placebo (changes in SBP/DBP: 34/7 mmHg, p<0.001). However, in the presence of metoclopramide and metoclopramide plus labetalol, handdrip induced lesser increases in blood pressure (changes in SBP/DBP: 23/7 mmHg, p<0.01 and 18/4 mmHg, p<0.01, for metoclopramide and metoclopramide plus labetalol treatment, respectively. We conclude that: 1.- Metoclopramide lowers blood in hypertensive patients; 2.- Metoclopramide attenuates blood pressure response to isometric handgrip and; 3.- Both compouds, labetalol and metoclopramide, seem to have a pharmacological interaction conceming blood pressure decrease. It is suggested a clinical significance for the metoclopramide effect

ABSTRACT

Twenty two (22) hypertensive patients were studied during handgrip test before and during metoclopramide treatment. Metoclopamide was intravenously administered at the rate of 7,5 µg/kg/min during a period of 30 min. Two placebo periods before and after metoclopramide infusion were employed. There was an increase of blood pressure and heart rate during handrgrid test; however, metaclopramide decreased blood pressure prior to handgrip test. In labetalol pretreated hypertensive patients (600-800 mg/daily po, during 7 days period), metoclopramide decreased greater blood pressure before and after handgrip test. Postmenopausal women reacted greater that premenopausal women. It appers that premenopausal women exhibit a vasculoprotecting effect during handgrip which should be attributed to estrogen secretion
