目的探讨心脏变时功能和患者焦虑情绪的相关性。方法随机选取2013年4月~2014年12月在我院行运动平板试验的患者101(男63,女38)例。记录静息时心电图、血压、运动中心率及血压变化、运动时间、运动量mets,监测血压、心率至运动后6 min。分别测量并计算运动后最大心率值、心脏变时性指数和运动结束后心率下降值。并对其进行焦虑自评量表(SAS)的问卷调查。所有数据采用SPSS17.0软件进行分析。结果 101例患者中焦虑39例,非焦虑62例。焦虑组与非焦虑组峰值心率/极量心率、心率储备和心脏变时性指数存在显著性差异;而焦虑相关因素的Logistic回归分析显示峰值心率/极量心率、心脏变时性指数、心率储备和代谢储备与焦虑并无显著性相关;焦虑评分与心脏变时功能相关性分析结果显示焦虑评分与运动时间呈显著性负相关,而与峰值心率/极量心率和心脏变时性指数呈显著性正相关。结论焦虑情绪会通过影响自主神经而影响冠心病患者的心脏变时功能,从而导致心脏变时功能不良假阴性结果的出现。
Objective To explore the correlation between cardiac time-varying function and anxiety in patients. Methods A total of 101 patients (63 males and 38 females) undergoing exercise treadmill test in our hospital from April 2013 to December 2014 were randomly selected. The resting electrocardiogram, blood pressure, exercise center rate and blood pressure changes, exercise time, exercise mets, blood pressure, heart rate to 6 min after exercise. The maximum heart rate, heart index and heart rate after exercise were measured and calculated respectively. And conducted self-rating anxiety scale (SAS) questionnaire. All data were analyzed using SPSS17.0 software. Results 101 patients were anxious in 39 cases, non-anxiety in 62 cases. There was a significant difference between peak anxiety group, non-anxiety group and non-anxiety group in peak heart rate / maximum heart rate, heart rate reserve and cardiac time-varying index. Logistic regression analysis showed that peak-to-peak heart rate, And metabolic reserve had no significant correlation with anxiety; anxiety score and cardiac function-related analysis showed that the anxiety score and exercise time was significantly negatively correlated with the peak heart rate / heart rate and heart rate index was significantly Positive correlation. Conclusions Anxiety can affect the cardiac function in patients with coronary heart disease by affecting autonomic nervous system, leading to the occurrence of false negative results of cardiac dysfunction.
