Abstract:
Objectives Understanding the characteristic changes of Keshan disease (KD) in different epidemic period to provide reference basis for prevention and teatment. Methods On the basis of medical record as fundamental element, the relative conditions of Keshan disease's prevailing and spreading period were compared. Results In high incidence years, familial aggregation [accounted for 12%(6/50)] and seasonal aggregation were found, and KD cases occurred mainly from May to September, which was 78% (39/50)of the total cases in the whole year. Circulatory dysfunction(gallop rhythm, pulmonary role, jugular venous engorgement, cyanosis of lips) was more severe in high incidence years than that in low incidence years(X2=8.53,P<0.01). The average age of incidence was (4.07±1.46) years old in high incidence years and (6.11±2.71) years old in low incidence years. The type constitution in high incidence years was significantly different from that in low incidence years (X2=40.68, P<0.01), and chronic type of KD accounted for 22.85%(707/3094),46.09%(53/115), respectively, in high and low incidence years. Conclusions Making a further research of seizure of disease, and improving diagnosis and cure management level are also the important content for prevention and cure research work of Keshan disease at right time.
