【摘要】 [目的]回顾性观察患者入院时血清钾水平与严重失代偿心力衰竭预后各指标的相关性。[方法]纳入2003年1月~2004年12月所有收治本院的、入院诊断为心力衰竭,心功能NYHA分级III~IV级的患者共289例,记录入院时血清钾水平,观察血清钾水平与预后的相关性。[结果]血清钾水平与静脉注射硝酸甘油用量呈正相关(P=0.043),血清钾水平增高增加病死率(P﹤0.0001)。[结论]入院时血清钾水平在4.2mmol/L左右严重失代偿性心力衰竭患者的预后较好,对于心力衰竭患者监测血清钾是非常必要的。更多还原

【Abstract】 [Objective] To observe the relationship between serum electrolytes and prognosis of severe decompensated heart failure.[Methods] 289 patients with NYHA III~IV heart failure in our hospital were collected from January 2003 to De-cember 2004.The serum potassium was recorded.The relationship between serum potassium and prognosis was evaluated.[Re-sults] The serum potassium had a positive relation with venous injection doses of nitroglycerin(P = 0.043).Hyperkalemia would increase the mortality(P﹤0.000 1).[Conclusion] The serum potassium level close to 4.2mmol/L is helpful for improv-ing prognosis of severe decompensated heart failure.It is very necessary to monitor serum potassium concentration.更多还原
