通过对22例急性心肌梗塞（AMI）早期患者进行早期心电图运动负荷试验（EET），结果发现阳性者10／22例（占45．45％），阳性者发生心脏事件较阴性者为高（X2＝4．77，P＜0.05）。平均随访（1．33±0．84）年，阳性组有5例发生梗塞后心绞痛，阴性组仅1例（P＜0.05）。EET者在3个月内恢复工作的其运动时的收缩压增加值为（7．80±3．19）kPa，总功率为（112.50±3．06）W，而超过3个月复工者则分别为（4．88±3．64）kPa和（82．14±11．29）W（P＜0．05）.同对照组比较，其住院时间明显减少（P＜0．005～0．0005），恢复工作的时间亦明显缩短。
The early electrocardiographic exercise stress test (EET) was performed in 22 patients with AMI in early stage. The results showed that 10/22 cases (45.45%) were positive, and those with positive cardiac events were higher than those with negative (X2 = 4.77, P <0.05). In the mean follow-up (1.33 ± 0.84) years, there were 5 cases of post-infarction angina in the positive group and only 1 case in the negative group (P <0.05). The ETS increased its systolic blood pressure (7.80 ± 3.19) kPa and its total power (112.50 ± 3.06) W during its exercise resumed within 3 months, while those who resumed work for more than 3 months (4.88 ± 3.64) kPa and (82.14 ± 11.29) W, respectively (P <0.05). Compared with the control group, the hospitalization time was significantly decreased (P <0.005-0). 0005), the time to resume work has also been significantly shortened.
