脑利钠肽浓度对中青年心肌梗死患者的危险分层与运动康复护理的指导

Instrution of risk stratification according to BNP concentration for exercise rehabilitation nursing in young and middle myocardial infarction patients

目的探讨脑利钠肽（BNP）是否可作为中青年心肌梗死患者运动康复护理危险分层的相对客观指标。方法分别测量56例中青年急性心肌梗死患者的BNP浓度和心脏彩超的左室射血分数（LVEF）值，利用各自指标对患者进行危险分层，评价其运动康复治疗的Barther评分，并与8例健康对照的相应指标进行比较。结果心脏超声LVEF值进行危险分层的各组间急性期血BNP浓度比较差异显著，但标准差过大，致方差不齐，各组间分层差异不明晰，彼此有组内交叉；利用心脏超声LVEF值进行运动康复护理评分，方差不齐，组间比较差异显著，但各组内分组差异不明显；利用BNP浓度进行危险分层，各组间比较差异显著，组内也有差异。结论心脏彩超LVEF值和BNP浓度有一定相关性，根据BNP进行综合危险分层对急性心肌梗死患者的康复运动护理有更客观的指导。

Objective To investigate whether BNP（brain natriuretic peptide） could be relatively objec- tive index for comprehensive risk stratification of exercise rehabilitation nttrsing in young and middle myocardial infarction patients. Methods BNP concentration and LVEF were measured respctively in young and middle myocardial infarction patients. Then the risk stratification was administrated based these index re- spectively and Barther Scores and significant statistical differences were calculated according to homogene- ity test for variance. Results Blood BNP concentrations in acute phase among the divided group based on EF risk stratification were significant difference, hence the standard deviation is large, which led to vail- ance nonhomogeneity, and stracification difference between groups is not clear and across-talking. Exercise rehabilitation nursing scores based on echocardiography EF value had significant difference even veariance is nonhomogeneity, hence the differ-ence is not clear beween groups.Exercise rehabilitation nursing scores based on BNP was administrated and significance is clear beween groups. Conclusions BNP concentra- tion and LVEF value had certain relationship and cross-talking among them.Risk stratification based on BNP concentration had objective instructions for exercise rehabili tation nursing in actue infarction myocar- dial pa-tients.
