克山病经过半个多世纪的综合防治,急型、亚急型克山病巳很少发生,但自然慢型克山病,以及由其他各型转变为慢型克山病者仍不断散在发生。因此,研究慢型克山病的防治,对降低克山病的病死率有重要意义。多因素回归分析表明,心脏扩大、心力衰竭、ST-T改变及既往病程是影响慢型克山病生存期的因素。本文采用时序检验,分析各预后因素不同强度对生存串的影响,绘制生存率曲线,现报告如下。
After more than half a century of comprehensive prevention and treatment of Keshan disease, acute and subacute Keshan disease have rarely occurred. However, patients with chronic Keshan disease and those with other types of Keshan disease are still scattered occur. Therefore, the study of prevention and treatment of chronic Keshan disease is of great significance to reduce the mortality of Keshan disease. Multivariate regression analysis showed that heart enlargement, heart failure, ST-T changes and the course of the past are the factors affecting the survival of chronic Keshan disease. In this paper, the use of time-series test to analyze the impact of different prognostic factors on the survival of the string, mapping the survival rate curve, are as follows.
