Evaluation of effects of self-treatment on patients with Keshan disease by echocardiography / 中国地方病学杂志

ABSTRACT

Objective To observe the change in cardiac shape and heart function and evaluate the effect of self-treatment on patients with Keshan disease by echocardiography. Methods To check the 31 patients with Keshan disease before the self-treatment, and follow them up in the 3rd and 6th months after self-treatment by echocardiography. The left atrium diameter(LAd), left ventricular end-diastolic diameter(LVEDd), the thickness of interventricular septum in end-diastolic(IVSTd), the thickness of LV posterior wall in end-diastolic (LVPWTd), left ventricular mass(LVM), left ventricular mass index(LVMI), left ventricular ejection fraction(LVEF) and mitral valve flow E/A ratio(E/A) were measured. Results The LAd[(35.8±5.1)ram] and LVPWTd[(9.3±1.0)mm] obviously decreased in the 3rd month after serf-treatment compared with prior self-treatment [ (37.0±5.0), (9.9± 1.2)mm](P<0.05). The LAd[(34.5±5.0)mini, IVSTd[(9.5±1.3)mm], LVEDd[(50.2±7.7)mm], LVPWTd [(8.7±1.1)mm], LVM[(196.1±87.2)g] and LVMl[(126.5±56.4)g/m2] obviously decreased in the 6th month after self-treatment compared with prior self-treatment [(37.0±5.0), (10.2±1.5), (51.3±8.1), (9.9±1.2)mm, (230.4±95.5)g, (144.0±54.6)g/m2] and in the 3rd month after self-treatment [(35.8±5.1)mm, (10.2±1.4) ram, (51.1±8.1)nun, (9.3±1.0)mm, (219.4±82.5)g, (136.8±50.0)g/m2] (P<0.05). The results of the mitral valve flow E/A ratio and LVEF in the 3nt month after self-treatment [1.0±0.5, (59.4±13.3)%] were increased compared with the prior self-treatment[0.9±0.5, (58.1±15.6)%], and the results in the 6th month after self-treat- ment[ 1.0±0.4, (60.7±13.6)%] were further inereased compared with before, but there was no signifieant differ- ence(P0.05). Conclusions Self-treatment of Keshan disease patients can improve the heart function by pre- venting left ventrieular remodeling and reversing. Echocardiography can be used as an essential technique to evalu- ate the effect of self-treatment on Keshan disease patients.
