目的分析云南不明原因心源性猝死的分布特点,探索危险因素,为制定切实有效的防治措施提供科学依据。方法根据《云南不明原因心源性猝死回顾性调查方案》,采用统一的调查表,收集病例信息进行统计分析。结果1.从1975年以后几乎每年都有病例,且每3～4年出现一个发病高峰,发病时间主要集中在每年的7,8月份;2.病区主要分布在经济、卫生状况较差的山区、半山区;3.发病具有明显的时间和空间聚集性;4.各个年龄段均有发病,但以青壮年人群为主;5.在研究对象中,既往服硒的病例所占的比例较少(2.5%)。结论云南不明原因心源性猝死发病具有明显的聚集性(家庭、村庄和时间聚集性),该病已成为一个严重的公共卫生问题,需要进一步探索研究。
Objective To analyze the distribution characteristics of sudden cardiac death of unknown cause in Yunnan, explore the risk factors and provide a scientific basis for making effective prevention and cure measures. Methods According to “Retrospective Surveys Program of Sudden Cardiac Death of Unexplained Cause in Yunnan Province”, a unified questionnaire was used to collect the case information for statistical analysis. Results 1. There are almost every year since 1975, with a peak incidence every 3 to 4 years. The onset time is mainly in July and August each year. 2. The wards are mainly distributed in poor economic and hygienic conditions Mountainous area, mid-mountain area; 3. The incidence of significant temporal and spatial aggregation; 4. All age groups have morbidity, but young and middle-aged population; 5. In the study, the proportion of previously served selenium cases Fewer (2.5%). Conclusion The incidence of sudden cardiac death of unknown origin in Yunnan has obvious aggregation (family, village and time aggregation). The disease has become a serious public health problem and needs to be further explored and studied.
