发布时间:2019-01-11 15:09
【摘要】:目的研究高原与平原不同环境条件下对健康青年男性24 h动态血压的影响。方法选择健康青年男性100名,先后在平原与高原不同环境下进行24 h动态血压监测。采用SPSS 17.0软件对数据进行统计分析。结果平原与高原24 h动态血压在24 h平均收缩压和舒张压、白昼(6∶00~22∶00)平均收缩压和舒张压、夜间(22∶00~6∶00)平均收缩压和舒张压、24 h平均心率、最大心率、最小心率、24 h收缩压、舒张压血压负荷、白昼收缩压、舒张压血压负荷、夜间收缩压、舒张压血压负荷存在显著性差异(P0.05);在收缩压和舒张压下降率、白昼收缩压和舒张压变异系数、夜间收缩压和舒张压变异系数方面无显著性差异(P0.05)。结论高原收缩压、舒张压均显著高于平原,高原24 h与白昼平均舒张压升高程度高于收缩压。高原血压负荷、24 h平均心率、最大心率、最小心率均高于平原,且离散程度较平原大。
[Abstract]:Objective to study the effect of high altitude and plain on 24 h ambulatory blood pressure in healthy young men. Methods 24 h ambulatory blood pressure monitoring was performed on 100 healthy young men in different environments of plain and plateau. The data were analyzed by SPSS 17.0 software. Results mean systolic and diastolic blood pressure, mean systolic and diastolic blood pressure at 24 h, mean systolic and diastolic blood pressure in day (6: 00 22: 00), mean systolic and diastolic blood pressure (DBP) at night (22: 00: 6: 00), mean heart rate at 24 h and maximum heart rate were found in plain and high altitude. Minimum heart rate, 24 h systolic blood pressure, diastolic blood pressure load, daytime systolic blood pressure, diastolic blood pressure load, night systolic blood pressure, diastolic blood pressure load were significantly different (P0.05). There was no significant difference in the decrease rate of systolic and diastolic blood pressure, the coefficient of variation in daytime systolic blood pressure and diastolic blood pressure, and the variation coefficient of night systolic blood pressure and diastolic pressure (P0.05). Conclusion systolic blood pressure and diastolic blood pressure at high altitude were significantly higher than those in plain, and the elevation of mean diastolic blood pressure at 24 h and day was higher than that of systolic blood pressure at high altitude. The mean heart rate, maximum heart rate and minimum heart rate in 24 hours were higher than those in plain, and the dispersion degree was larger than that in plain.
