摘要
目的 探讨老年高血压患者微量白蛋白尿与左心室肥厚之间的关系。方法 对114例年龄超过60岁的高血压患者先测定每个患者的微量白蛋白尿的含量，应用超声心动图测量左室室间隔厚度（IVST）及左室厚壁厚度（PWT），根据公式测得左室重量指数（LVMI）。结果 与尿微量白蛋白阴性组相比，尿微量白蛋白阳性组患者收缩压更高、舒张压更低、脉压更大，并且左室重量指数明显升高。结论 高血压患者，尤其是老年高血压患者微量白蛋白尿即早期的肾脏损害与高血压左室肥厚有密切关系。
Objective To explore the relationship between microalbuminuria and left ventricular hypertrophy in subjects with essential hypertension in elderly. Methods IVST and PWT were measured by echocardiography in 114 essential hypertension patients who were older than 60 years. LVMI of all patients were calculated. Microalbuminuria was defined as UAE of 30 - 300 mg/24h, The subjects were divided into two groups, ie group with or without microalbuminuria. Results LVMI was different significantly between the groups with and without microalbu- minuria. The groups with microalbuminurine had higher level of Systolic blood pressure , pulse pressure and LVMI, while they had lower diastolic blood pressure. Conclusion In the hypertensive patients, especially in the elderly one, there was a significant relationship between microalbuminuria and left ventricular hypertrophy.
