不同习服时间对军人急进高原后心功能的影响及干预研究.

Objective: To study the effect of acclimatization time on heart function of soldiers rushing into plateau and the countermeasures. Methods: 241 male soldiers who needed to rush into plateau were selected. Their heart function under different acclimatization time at high altitude were observed, and targeted interventions explored. Results: When compared to before entering the plateau, the HP, LVEF, LVFS, CO and LVEDVI levels 3 days into plateau, the HP, LVEF, LVFS and LVEDVI levels 7 days into plateau, the HP, LVEF and LVEDVI levels 14 days into plateau, the HP level 30 days into plateau, all have statistical significance (P＜0.05). when compared to 3 days into plateau, the HP, LVEF, LVFS, CO and LVEDVI levels 30 days and 60 days into plateau all have statistical significance (P＜0.05). The HP level 30 days into plateau was lower than that in 7 days into plateau. The differences among HP, LVEF and LVEDVI levels between 60 days and 7 days into plateau were statistically significant (P＜0.05). The HP levels 30 and 60 days into plateau were both lower than that 14 days into plateau, and the differences statistically significant (P＜0.05). Conclusion: The heart function of soldiers will be greatly influenced when they are sudden at high altitude. With effective interventions and increase of acclimatization time, the influence will gradually disappear and will not affect the normal work and training of soldiers. [ABSTRACT FROM AUTHOR]
