老年单纯性收缩期高血压与左室重构和心律失常关系的探讨

The relationship of left ventricular remodeling and cardiac arrhythmia in aged patients with isolated systolic hypertension

目的:探讨老年单纯性收缩期高血压与左室重构和心律失常的关系,摸索最佳的临床治疗高血压方案。方法:观察103例老年单纯性收缩期高血压患者的左室构型及发生心律失常的情况。结果:左室重构中的正常构型(1型)、向心型重构(2型)、向心性肥厚(3型)、离心性肥厚(4型)的比率依次为49.5%、4.9%、14.6%、31.1%,老年单纯性收缩期高血压的心律失常的发生随左室构型不同存在显著性差异,主要表现在CVA的发生率,3、4型与1型相比具有显著性差异。结论:老年单纯性收缩期高血压患者复杂心律失常的发生与左室构型有关,伴有左室肥厚者,可能有心律失常易发性的病理基础。

Objective： To research the relationship of left ventricular remodeling and the cardiac arrhythmia in aged with isolated systolic hypertension, and to explore an optimal therapy. Methods： The left ventricular remodeling and the cardiac arrhythmia in 103 aged patients with isolated systolic hypertension were observed. Results： The incident rates of type Ⅰ, Ⅱ, Ⅲ, Ⅳ of left ventricular remodeling are 49.5%, 4.9%, 14. 6% and 31.1%. There are differences between the incidences of cardiac arrhythmia and different types of left ventricular remodeling. The incidence of CVA had significant difference between type Ⅲ, Ⅳ and type Ⅰ. Conclusion. The incidence of cardiac arrhythmia in aged isolated systolic hypertension related to the types of left ventricular remodeling, left vtntricular thickness, possibly is the pathologic base of arrhythmia.
