冠心病合并糖尿病患者营养风险评分与心功能的关系

Relation between the nutrition risk score and cardiac function in patients with coronary heart disease accompanying diabetes mellitus

目的观察营养风险筛查2002(nutrition risk screening 2002,NRS 2002)评分系统在我国冠心病患者的适用性及评分结果与心功能的关系。方法对我院2012年3-7月收治的冠心病合并糖尿病患者120例,依照NRS2002评分标准进行营养风险评分,并观察其与心功能的关系。结果 120例中,营养风险评分<3分83例,占69.2%;≥3分37例,占30.8%。≥3分组较<3分组心功能差,<3分组心脏射血分数(ejection fraction,EF)值为56.55%±7.58%,≥3分组EF值为51.00%±9.60%,差异具有统计学意义(P<0.01)。<3分组心功能Ⅲ级和Ⅳ级者占总体的5.8%,而≥3分组占17.5%。NRS2002评分与心功能分级呈正相关,相关系数为0.643(P<0.01)。结论应用NRS2002可以了解患者营养状态,对提示冠心病合并糖尿病患者不良临床结局风险有一定意义。

Objective To observe the relation between nutrition risk score on nutrition risk screening 2002 （NRS 2002） scoring system and heart function in patients with coronary heart disease accompanying diabetes meUitus （DM）. Methods Relation between nutrition risk score on the NRS2002 scoring system and heart function was observed in 120 patients with coronary heart disease accompanying DM admitted to our hospital from March 2012 to July 2012. Results The nutrition risk score was 〈 3 and i〉 3 in 83 （69.2%） and 37 （30.8%） out of 120 patients, respectively. The heart function was poorer in the patients with their nutrition risk score 〉I 3 than in those with their nutrition risk score 〈 3. The EF was 56.55% ＋ 7.58% and 51.00% ~ 9.60% for the patients with their nutrition risk score I〉 3 and for those with their nutrition risk score 〈 3, respectively （P 〈 0.01）. The heart function grades Ill and IV accounted for 5.8% and 17.5% in the patients with their nutrition risk score 〈 3 and in those with their nutrition risk score ~〉 3, respectively. The nutrition risk score on the NRS2002 scoring system was positively related with the heart function grade with a correlation coefficient of 0.643 （P 〈 0.01）. Conclusion NRS2002 scoring system can show the nutritional status of patients with coronary heart disease accompanying DM, thus playing a certain role in predicting the adverse clinical outcome of such patients.
