激光穴位照射对冠心病人左心功能的影响及与针刺作用的比较

<正> 针刺能够改善左心功能并用于治疗冠心病。实验和临床研究也揭示激光穴位照射和针刺穴位产生的调整和镇痛等作用又非常相似。那么激光穴位照射对冠心病人的左心功能有何影响?激光穴位照射和针刺穴位对冠心病人的左心功能的影响有何异同?本工作观察了36例激光内关穴照射和10例针刺内关穴后冠心病人左心功能变化情况,并进行了比较。

THE EFFECT OF LASER AT ACUPOINTS ON CORONARY PATIENT'S LEFT VENTRICULAR FUNCTION AND THE COMPARISON WITH THE EFFECT OF ACUPUNCTURE

We observed the S.T. I. change in 46 cases with coronary heart disea- se. 36 cases of them were treated with laser at Neiquan points bilaterlly for 10 m nutes. The rest were treated with electroacupuncture at same po- ints for samc minutes. Then, we compared the action of laser and electro- acupuncture. The results showed that the S.T. I. in 31 of 36 the cases shortened after laser at the poiuts and in 5 cases it remained unchanged or increased. The shortened cases amounted to 86.1%, PEP, ICT, and PEP/LVET reduced by 8.7%, 19.6% and 8.3%, respectively. But LVET/ICT and the coefficient of heart capability increased by 13.5% and 19.56%, respectively. Before and after laser at points the difference was very remrkable (P< 0.001) The results also showed that the S.T.I. in 9 of the other 10 cases shortened after electroacupuncture for, 10 minutes and in 1 case it i- ncreased. The shortened cases amounted to 90%. PEP, ICT and PEP/LVET reduced by 9. 4% 11.2% and 10.8% respectively. LVET/ICT and the coe- fficient of heart capability increased by 15.01% and 18.18%, respectively. The difference was very remarkable in the same way(P<0.001). The shortening of S.T. I. reflects the improvement of left ventricular function. Both laser and electroacupuncture almost showel similer changes in some parameters of S.T.I. in direction and range. Therefore, we infer that laser at points may have the same affecting links and mechanisms as electroacupuncture in improvement of left ventricular function.
