【摘要】 目的　探讨 70岁以上老年慢性心力衰竭病人低钠血症的发生与日常生活中低盐饮食习惯的相关性。方法　高龄组 ( 50例 ,70～ 93岁 )慢性心力衰竭住院病人低钠血症发生的情况与对照组 ( 4 3例 ,60～ 69岁 )慢性心力衰竭患者的比较 ;高龄组病人出院后采取正常钠盐摄入 ,3年中再住院者 ( 2 1例 )低钠血症发生的情况与第一次住院时发生的情况进行比较。结果　高龄组中有 11例自行限制钠盐摄入或长期饮食不佳者在纠正心力衰竭时全部发生低钠血症 ,对照组 7例限制钠盐摄入或长期饮食不佳者 ,有 1例发生低钠血症。发生低钠血症高龄组明显多于对照组 ,(P <0 .0 1)。出院后的 3年中 ,高龄组病人采取正常钠盐饮食 ,其中 2 1例再住院病人无 1例发生低钠血症 ,与第一次住院相比 ,( P <0 .0 5)。结论　 70岁以上慢性心力衰竭病人日常生活中不宜采用低盐饮食 ,因为在纠正心力衰竭的同时 ,很容易出现危及生命的低钠血症更多还原

【Abstract】 Objective To explore the relationship between hyponatremia and a lifestyle of low salt diet in elderly patients aged of over 70 with chronic heart failure.Methods 93 cases of chronic heart failure were diveded into two groups:high aged group of 50 subjects aged of 70～93 and the control group of 43 subjects aged of 60～69.The incidence of hyponatremia was compared between the two groups.The patients in high aged group had a normal salt intake after leaving the hospital.During the following 3 years,21 patients in high aged group were rehospitalized.Their morbidity of hyponatremia was compared with that during their first hospitalization.Results There was a significant higher morbidity of hyponatremia in high aged group, of which 11 subjects underwent it with long term low salt diet or poor dietary, than that in the control group,of which only one of seven subjects underwent hyponatremia,P<0.01.21 in high aged group were rehospitalized with other episodes of heart failure with a normal salt intake in the next three years,none of them experienced hyponatremia, and there was a statistical difference in comparison with the condition occurred in high aged group during the first hospitalization,P<0.05.Conclution Dietary salt restriction might not be beneficial for patients aged of over 70 with chronic heart failure,because it was liable to increase hyponatremia risk that harmed the patients when their heart failure were treated.更多还原
