福州地区中老年人心肺运动试验中ST段异常特征及影响因素

Study on ST segment abnormal characteristics and influencing factors in cardiopulmonary exercise test in middle-aged and elderly people in Fuzhou Area

目的通过心肺运动试验了解福州地区中老年人ST段改变的特征并对其可能的影响因素进行分析,以期对心血管预防提供理论指导。方法收集2017—2023年于联勤保障部队第九○○医院体检中心进行健康体检的987例个体数据,对其进行心肺运动试验,采用logistic回归分析ST段异常的影响因素。结果共有234例发生ST段异常,异常率为23.72%。其中ST段压低148例(14.99%),ST段抬高52例(5.27%),ST段延长13例(1.32%),ST段缩短21例(2.14%)。ST段异常组的运动最大心率(/min)、静息收缩压(mm Hg)、静息舒张压(mm Hg)、峰值收缩压(mm Hg)、峰值舒张压(mm Hg)、二氧化碳通气当量(%)及Borg评分(分)均高于正常组,且差异具有统计学意义。多因素回归结果显示,峰值收缩压(mm Hg)、二氧化碳通气当量(%)及Borg评分(分)为ST段压低的独立影响因素;峰值收缩压(mm Hg)、Borg评分(分)为ST段抬高的独立影响因素(OR>1)。结论峰值收缩压(mm Hg)、二氧化碳通气当量(%)及Borg评分(分)为中老年人群心肺运动试验中ST段异常发生的影响因素,对其测量对于心血管健康评价及治疗具有重要意义。

Objective To investigate the characteristics of ST segment changes in middle-aged and elderly people in Fuzhou through cardiopulmonary exercise test and to analyze its possible influencing factors,in order to provide theoretical guidance for cardiovascular prevention.Methods A total of 987 individuals undergoing health examination at the physical examination center of 900TH hospital of joint logistics support force from 2017 to 2023 were collected as study subjects,and cardiopulmonary exercise tests were performed,and the exercise maximum heart rate(/min),resting systolic blood pressure(mm Hg),resting diastolic blood pressure(mm Hg),peak systolic blood pressure(mm Hg),,carbon dioxide ventilation equivalent(%),Borg score(score)and other index data were collected,using logistic regression to analyze the influencing factors of ST segment anomalies.Results A total of 234 ST-segment abnormalities occurred,and the abnormal rate was 23.72%.Among them,148 cases(14.99%)were depressed in ST segment,52 cases(5.27%)were elevated in ST segment,13 cases(1.32%)was extended in ST segment,and 21 cases(2.14%)was shortened in ST segment.The STsegment abnormal group had higher exercise maximum heart rate(/min),resting systolic blood pressure(mm Hg),resting diastolic blood pressure(mm Hg),peak systolic blood pressure(mm Hg),peak diastolic blood pressure(mm Hg),carbon dioxide ventilation equivalent(%)and Borg score(score)than the normal group,and the differences were statistically significant.The results of multivariate regression analysis showed that peak systolic blood pressure(mm Hg),carbon dioxide ventilation equivalent(%)and Borg score(score)were the influencing factors in the ST segment depression;the peak systolic blood pressure(mm Hg)and Borg score(score)were the influencing factors in the ST segment elevation(OR>1).Conclusion Peak systolic blood pressure(mm Hg),carbon dioxide ventilation equivalent(%)and Borg score(score)are the influencing factors of ST segment abnormalities in cardiopulmonary exercise test in middle-aged and elderly people,and their measurement is of great significance for cardiovascular health evaluation and treatment.
