Resumen

Con objeto de analizar los factores etiopatogénicos del cor pulmonale crónico en la neumoconiosis del carbón, se estudiaron 190 casos de sobrecarga ventricular derecha, diagnosticados por criterios electrocardiográficos firmes, y excluyendo la presencia de cardiopatía izquierda. Estos 190 casos fueron divididos en tres grupos:

Grupo I. Mineros del carbón sin neumoconiosis (18 pacientes).

Grupo II.-Mineros del carbón con neumoconiosis simple (45 pacientes) y

Grupo III. Mineros del carbón con neumoconiosis complicada (127 pacientes). En todos los grupos se estudiaron: la edad media y el tiempo medio de exposición al riesgo pulvígeno en los puestos laborales de picadores y barrenistas, la función respiratoria, la radiología de tórax, la presencia o no de insuficiencia cardíaca derecha y la aparición de sobrecarga auricular derecha electrocardiográfica acompañante a la sobrecarga ventricular.

En los grupos I y II se evidenció una relación absoluta entre la hipoxemia, producida por la insuficiencia ventilatoria obstructiva de la enfermedad pulmonar obstructiva crónica y el cor pulmonale crónico. Este hallazgo sugiere, que la desaturación de O2 es la causa fundamental de la sobrecarga ventricular derecha y no la Neumoconiosis.

En el grupo III, la incidencia de cor pulmonale crónico es aproximadamente el doble de los otros dos tipos, lo que sugiere una afectación pulmonar más severa en la neumoconiosis complicada. En el 95,2% de los casos, se presentó la insuficiencia ventilatoria de tipo obstructivo y únicamente en el resto de los casos apareció la insuficiencia ventilatoria de tipo restrictivo. La hipoxemia, como causa de sobrecarga ventricular derecha, ya sea aislada o asociada a otros factores, en un 64% de los casos; en el resto de los casos, sin hipoxemia, podría aceptarse la destrucción del lecho vascular pulmonar como causa determinante del cor pulmonale crónico.

Summary

In order to analyze the pathogenic factors of chronic pulmonary heart in pneumonoconiosis of carbon, the authors studied 190 cases of right ventricular strain, diagnosed by firm electrocardiographic criteria, and excluding the presence of left cardiopathy. These 190 cases were divided into three groups: GROUP I Coal miners without pneumonoconiosis (18 patients); GROUP II Coal miners with simple pneumonoconiosis (45 patients) and GROUP III Coal miners with complex pneumonoconiosis (127 patients). In all the groups the following was studied: average age and average time exposed to the powder risk in the jobs of picker and driller the respiratory function; the radiology of the thorax; the presence or absence of right cardiac insufficiency; and the appearance of electrocardiographic right auricular strain accompanying the ventricular strain.

In groups I and II an absolute relationship between hypoxemia, produced by obstructive ventilatory insufficiency of the chronic obstructive pulmonary disease and the cronic pulmonary heart, was made evident. This finding suffests that the desaturation of O2 is the basic cause of the right ventricular strain and not pneumonoconiosis.

In group III the incidence of chronic pulmonary heart is approximately twice that of the other two types, which suggests a more severe pulmonary affectation in complex penumonoconiosis. In 95.2% of the cases obstructive-type ventilatory insufficiency was present and only in the rest of the cases did restrictive type ventilatory insufficiency appear. Hypoxemia appeared as the cause of right ventricular strain, either isolated or associated with other factors, in 64% of the cases; in the rest of the cases, without hypoxemia, the destructionof the pulmonary vascular bed could be accepted as the determining cause of chronic pulmonary heart.
