III期运动对冠心病稳定期患者心肌缺血的影响追踪性研究

A Tracking Research of Influence of III Period of Exercise in Myocardial Ischemia Patient Who was in Stationary Phase of Coronary Disease

目的：探讨III期运动在心脏康复中的效果，为评估及制定安全的日常生活活动能力范围提供依据。方法：22名参加II期运动心脏康复训练的冠心病稳定期患者，1年后通过递增负荷运动实验对其ST段下移幅度进行测定。结果：受试者St段下降幅度在TreadmillGXT第1、II、III负荷等级末较II期运动心脏康复后均有显著性降低（P〈0．05或P〈0．01），在安静时及第IV负荷等级末未出现显著性改变（P〉0．05），维持在原有II期运动·22脏康复前的水平。结论：长期运动心脏康复可维持并改善冠心病稳定期患者的心肌缺血状况。在TreadmillGXT中，第IV负荷等级末所对应的强度可作为冠心病稳定期患者长期运动处方中安全运动强度的上限。

Objective： To discuss the efficacy of III period of exercise in cardiac rehabilitation, and provide basis of assessing and formulating abilities range of safety activities of daily life. Meth- ods： 22 patients with coronary disease in stationary phase took part in II period of exercise of cardi- ac rehabilitation train, they were measured the ST segment depressed degree by the increasing load movement experiment after 1 year. Results： in the end of No. I, No. II and No. III load level, ST seg- ment depressed degree of subjects had significantly decrease after II period of exercise in cardiac rehabilitation （P〈0.05 or P〈0.01）. In rest state and the end of No. IV load level ST segment de- pressed had no significant change （P〉0.05） and maintained the level before the II period of exer- cise of cardiac rehabilitation. Conclusion： Long-term exercise of cardiac rehabilitation can keep and improve the myocardial ischemia condition of coronary disease patients in stationary phase. In Treadmill GXT, the strength of the end of No. IV load level can become the upper limit of safety movement strength of coronary disease in stationary ohase natients.
