The early cardiac involvement is well known in arterial hypertension, particulary the diastolic and left ventricular hypertrophy. The right ventricle and pulmonary circulation may likewise be affected early in the course of disease. Scarce though it is, studies on the right repercussion of hypertension have shown an increase in pulmonary resistance and right-sided pressures in hypertensive patients. In spite of the limitations arising from the complex geometry of the right ventricule, echocardiography may be the most important non-invasive technique in the evaluation of the structural and functional repercussion of hypertension on the right ventricle. Our studies have revealed an increase in the diastolic thickness of the right ventricular free wall in hypertensive patients, as well as a good correlation between the diastolic thickness of the free walls of both ventricles. Most studies suggest a functional relationship between both ventricles. Structural alterations may occur in the right ventricle, along with hemodynamic alterations, thus suggesting structural and functional similarity of both ventricles, regarding cardiac response to arterial hypertension.
早期心脏受累在动脉高血压中是众所周知的,尤其是舒张功能障碍和左心室肥厚。右心室和肺循环在疾病过程早期同样可能受到影响。尽管关于高血压对右心影响的研究较少,但已表明高血压患者的肺阻力和右心压力会增加。尽管右心室复杂的几何结构带来了局限性,但超声心动图可能是评估高血压对右心室结构和功能影响的最重要的非侵入性技术。我们的研究发现,高血压患者右心室游离壁的舒张期厚度增加,且两个心室游离壁的舒张期厚度之间存在良好的相关性。大多数研究表明两个心室之间存在功能关系。右心室可能会出现结构改变以及血流动力学改变,这表明在心脏对动脉高血压的反应方面,两个心室在结构和功能上具有相似性。
