【摘要】：目的分析高温环境下高强度训练对作战训练(作训)人员心脏的影响。方法选择解放军252医院于2015年7月1日~2016年8月31日收治的因高温高强度训练出现不适的作训人员38例,均为男性,年龄18~23(20±1.8)岁。所有患者入院后均检测血常规、肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)、心肌肌钙蛋白I(cTn I)、肌酐(Cr)、丙氨酸氨基转移酶(ALT)、N末端脑钠肽前体(NT-pro BNP)等,诊断并分析患者临床症状。结果出现心脏相关症状胸闷、气短12例(31.6%),心悸10例(26.3%)。此外,9例(23.7%)在出现不适症状时血压偏低。12例(31.6%)出现心电图改变,7例(18.4%)诊断为心律失常。5例(13.2%)出现心肌损伤,6例(15.8%)考虑存在多器官功能损害。20例(52.6%)诊断为中暑,其中6例(15.8%)同时存在肝肾功能受损,考虑为热射病。患者入院后给予补液及相应对症支持治疗,均好转出院,肝肾功能指标及心肌酶均恢复正常,无明显后遗症。结论高温环境下的高强度训练会引起作训人员心脏等器官损伤,应科学合理设计训练,使作训人员提高对高温环境高强度训练的适应能力,减少心肌损伤,提高部队战斗力。
[Abstract]:Objective To analyze the effect of high-intensity training on the heart of the training in combat training (training) under high-temperature environment. Methods 38 cases of malaise in high-temperature and high-intensity training from July 1,2015 to August 31,2016 were selected to be male and 18-23 (20-1.8) years old. Blood routine, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), cardiac troponin I (cTn I), myoglobin (Cr), alanine aminotransferase (ALT), and N-terminal brain natriuretic peptide (NT-pro BNP) were all detected after admission. Results The heart-related symptoms of chest distress, shortness of breath in 12 (31.6%) and palpitations (26.3%). In addition,9 (23.7%) had a low blood pressure in the presence of malaise.12 (31.6%) had an electrocardiogram change,7 (18.4%) had an arrhythmia,5 (13.2%) had myocardial injury,6 (15.8%) considered the presence of multiple organ dysfunction.20 (52.6%) were diagnosed with heatstroke, In 6 of them (15.8%), the function of liver and kidney was impaired, and it was considered to be a heat-emitting disease. After admission, the patient was given the fluid replacement and the corresponding symptomatic support treatment, and all the patients were discharged, the functional indexes of the liver and the kidney and the myocardial enzymes recovered to normal, and there was no apparent sequela. Conclusion The high-intensity training in the high-temperature environment can cause the injury of the heart and other organs of the training personnel, and the training should be scientifically and reasonably designed, so that the training personnel can improve the adaptability of high-strength training to the high-temperature environment, reduce the myocardial damage and improve the fighting capacity of the troops.
