1975-2004年云南不明原因心源性猝死回顾性调查

目的 探索云南不明原因心源性猝死的流行病学规律和发病特点.方法 选择曾上报云南不明原因心源性猝死病例的23个县进行云南不明原因心源性猝死病例回顾性调查及病例搜索,以1975-2004年21年中的猝死病例为调查对象,逐级培训调查员,统一调查方法,统一制定及下发调查表格,死者家属、见证人、救治医生、村干部为询问对象. 结果 299例被定为"云南不明原因心源性猝死",其中死亡病例286例(95.65%),同发病例13例(4.35%).死亡病例中有36例(12.04%)为该次回顾性调查中搜索到.该病发病具有明显的家庭和村庄聚集性、明显的季节分布、青壮年多发等流行病学特点及突然发病、突然死亡的发病特点;病区自然村主要分布在2 1002 300 m高海拔地带.结论 云南不明原因心源性猝死是一种新的、尚未被完全认知的一类疾病;可能是由多种病因共存,遭受某种致病因子打击而表现出以"猝死"为主要发病特点的疾病.
