原发性高血压左心室肥厚及构型与冠状动脉狭窄的关系

Relationship between hypertensive left ventricular hypertrophy or patterns of hypertrophy and coronary stenosis

目的 探讨原发性高血压左心室肥厚(LVH)及不同构型与冠状动脉狭窄的关系。方法 对1 47例有或无左心室肥厚(LVH)的原发性高血压患者进行超声心动图和冠状动脉造影检测。结果 原发性高血压LVH的程度与其发生冠状动脉狭窄级数的相关系数为r=O.58(P<O.05);原发性高血压LVH不同构型之间冠状动脉狭窄≥75％和多支冠状动脉狭窄的发生率有明显的差异,非对称性LVH发生率较高。结论 冠状动脉狭窄的程度和范围与LVH具有一定的联系,因此,对于肥厚程度较重、不对称性LVH的原发性高血压患者要给予高度重视。

Objective To explore the relationship between hypertensive Left ventricular hypertrophy (LVH) or patterns and coronary artery stenosis. Methods The echocardiography and coronary anteriography were applied to examine 147 patients with LVH or without LVH. Results The degree of LVH and coronary artery stenosis grade has close relationship(r = 0. 58,P<0. 05). The different patterns of LVH were significantly different in incidence of coronary artery stenosis ≥75% and multivessel disease,and incidence of asymmetric LVH was higher. Conclusion Hypertensive patients with severe LVH and asymmetric LVH should be attached great importance.
