摘要
目的 分析 12 0例原发性高血压患者左心房大小及其影响因素。方法 原发性高血压患者 12 0例 ,男 5 9例 ,女 6 1例 ,年龄 33～ 78岁。全部患者分为两组 ,年龄≥ 6 0岁为老年组 (6 0例 ) ,年龄 <6 0岁为非老年组 (6 0例 )。每组根据心脏超声分为左心室肥厚和无左心室肥厚两个亚组。左心房内径大于 4cm为左心房扩大 ,面积 长度法左心室重量指数男性 >89g m2 ,女性 >77g m2 为左心室肥厚。结果 非老年组 4 3%、老年组 73%合并左心室肥厚 ;非老年组 14例 (2 3% )、老年组 2 2例 (37% )合并左心房扩大 ;37%患者左心房扩大和左心室肥厚同时并存 ,2 0 %患者仅有左心房扩大 ;两组左心房扩大者共 36例 ,其中老年组合并左心室肥厚占 5 0 % (18 36 ) ,非老年组合并左心室肥厚占 2 2 % (8 36 ) ;多因素分析提示超重、血压水平与左心房扩大无显著相关性 ,年龄和左心室重量指数同左心房扩大显著相关。结论 年龄与左心室肥厚是原发性高血压左心房扩大的重要影响因素。
Objective To evaluate the factors affecting left artrial (LA)size in hypertensive patients. Methods120 hypertensive patients consisting of 59 males and 61 females aged from 33～78 years were studied. The diameter of LA larger than 4 cm was defined as LA enlargement. Left ventricular mass index higher than 89 g/m2(male)or 77 g/m2(female)was defined as left ventricular hypertrophy. The patients were divided by age into 2 groups(<60 and ≥60 years).Results Left ventricular hypertrophy(LVH) was present in 43% of patients aged <60 years and in 73% of patients aged ≥60 years. Left atrial enlargement was present in 37% of elderly and in 23% of younger patients, and in 37% of patients with and 20% of patients without LVH.The older age group with left ventricular hypertrophy contained 50% of all patients with LA enlargement,while the younger age group contained only 22%.Multivariate analysis showed that left atrial englargement was not correlated with overweight or level of blood pressure; but had notable correlation with age or LVH.Conclusion Age or LVH is the important factor affecting left atrial size in hypertensive patients.
