为了确定精神应激与心肌缺血之间的关系,用微型探头γ心功能仪对10例正常人及30例冠心病(CAD)患者进行精神应激试验及运动踏车试验。结果正常对照组于精神负荷状态下左室射血分数(LVEF)由安静时58.2%±9.8%增至63.8%±6.1%(P<0.01),运动试验 LVEF 增至68.2%±12.9%(P<0.01);而 CAD 组中28例患者精神应激状态下LVEF 比对照组降低12.9%±5.4%,持续时间5.4±2.0分钟,22例在运动试验时 IWEF 降低16.6%±8.6%,两者符合率为96%。精神应激对诱发心肌缺血的敏感性为93%。表明心肌缺血与精神因素有密切关系。
In order to determine the relationship between mental stress and myocardial ischemia, mental stress test and exercise treadmill test were performed in 10 normal subjects and 30 patients with coronary artery disease (CAD) using the mini-probe γ-heart function instrument. Results The LVEF increased from 58.2% ± 9.8% to 63.8% ± 6.1% (P <0.01) in the normal control group and 68.2% ± 12.9% in the exercise test (P <0.01). In the CAD group, LVEF was reduced by 12.9% ± 5.4% and duration of 5.4 ± 2.0 minutes, and IWEF decreased by 16.6% ± 8.6% in the exercise test in 28 patients in the stress group The coincidence rate is 96%. Mental stress on myocardial ischemia induced sensitivity was 93%. That myocardial ischemia and mental factors are closely related.
