Evaluation on self-treatment of patients with chronic Keshan disease in Fuyu County, Heilongjiang Province / 中国地方病学杂志

ABSTRACT

Objective To evaluate the self-treatment effectiveness on patients with ehwnic Keshan disease.Methods Twenty patients with chronic Keshan disease were selected from individuals with Keshan disease in Fuyu County,Heilongjiang Province.They were trained three times every three months of self management including pathogenetic condition education,general guidance,drug therapy,and they also taught how to adiust the doBe of drug according to their illness.Major symptom score,heart rate(HR),ultrasoundcardiogram (UCG)index and cardiac functional grading of these patients at basehne,after 3 months and 6 months of treatment were compared.Results The 20 patients rated their main symptoms score as(15.03 ±6.77)before self- treatrnent,and significantly decreased to(7.25±4.82)and(6.70±4.90)after 3 and 6 months treatment(P<0.01); the heart rate(HR) was (76.40±12.06) beats per minute(bpm)before self-treatment,and dramatically decreased to (69.95±12.63),(67.15±9.76)bpm after 3 and 6 months treatment(P<0.01).As for UCG detecting index,left atrial diameter(Lad)aIld left ventricular end-diastolic diameter(LVEDd)Was(37.85 ±5.23)nun and(52.49± 9.38)mm separately before self-treatment,and notablely decreased to(36.77 ±5.63),(52.15 ±9.24)mm,and (35.29±5.50),(50.81±8.88)mm respectirely after 3 and 6 months of treatment(P<0.01 or<0.05);left ventricuIar ejection fractiOII(LVEF)markedly increased(P<0.05),from(55.15±15.80)%at baseline to(57.35± 12.51)%at 3 months and(60.30±13.42)%at 6 months;there were no significant differences in mitral flow E/A ratio changes before and after treatment(P>0.05);compared with prior to the treatment.cardiac function grading was significantly better aftertreatmentfor 3 months(T=36.0,P<0.05),but not after 6 months(T=17.5,P> 0.05).Conclusions The patients'serf-treatment is effective,which we recommend to uphold and widespread.
