急性失代偿性心力衰竭患者血清肌钙蛋白T水平检测的价值

目的：研究肌钙蛋白T的水平变化在急性失代偿性心力衰竭患者预后的价值。方法：选取急诊重症监护室收治的68例急性失代偿性心力衰竭患者,按照cTnT的水平分为cTnT阳性组（27例）和cTnT阴性组（41例）。观察两组患者室性期前收缩发生率、APACHEⅡ评分、在ICU入住时间、住院时间、住院病死率、随访出院后6个月内再入院率及6个月死亡率。结果：两组治疗期间利尿剂、扩血管药物使用、多巴胺和（或）多巴酚丁胺的使用和两组患者6个月随访期间死亡率比较差异无统计学意义（P〉0.05）。入院时APACHEⅡ评分、在ICU入住时间、住院时间、住院病死率及出院后6个月内再入院率比较均显示差异有统计学意义（P〈0.05）。结论：肌钙蛋白T水平是与治疗无关的危险因素之一。伴有肌钙蛋白T升高的急性失代偿性心力衰竭患者有较高的室性期前收缩发生率、较长的住院时间、短期预后差,监测cTnT水平对急性失代偿性心力衰竭患者的病情评估和短期预后有重要作用。

Value of cardiac T in the monitoring of acute decompensated heart failure

Objective：To evaluate the value of cardial T（cTnT） in the monitoring of acute decompensated heart failure.Methods：A total of 68 consecutive acute decompensated heart failure to emergency intensive care unit.All the patients were divided into two groups according to the levels of cTnT：positive group（n=27） and negative group（n=41）.Clinical laboratory parameters and the outcome were compared between two groups.Results：There were no significant differences in use of the diuretic,use of the vasodilator,use of the dopamine and（or） dobutamine and mrtality over the 6-month follow up between two groups（P0.05）;there were higher APACHEⅡscores,longer ICU stays,hospital mortality and again into hospital in 6-month in the elevated cTnT group than those in the normal cTnT group（P0.05）.Conclusion：The level of troponin T is one of the risk factor of acute decompensated heart failure.Their days of stay in hospital is longer and prognosis is poor.The detection of cTnT is valuable in evaluating the severity of disease and the clinical prognosis for the treatment of these patients.
