本文对１０年间收住的１５８７例肺心病患者，对死亡的１２１例（７．６２％）进行回顾性统计分析。其中男性占８１．８％，女性占１８．２％，两者有显著差异。统计资料表示：昆明地区虽年温差不大，但死亡月份仍集中于１２月至２月，死亡病程在１０年以上占７９．３％。死亡病例中有吸烟史为８９．２％，提示吸烟是导致肺心病的主要原因之一。 In this paper, we retrospectively analyzed the mortality of 121 cases (7.62%) of 1587 pulmonary heart disease patients admitted in 10 years. Among them, 81.8% were male and 18.2% were female, showing significant differences between the two. Statistics show that although the annual temperature difference is not large in Kunming, the death month is still concentrated in December and February, and the death course accounts for 79.3% in 10 years or more. Smoking history of death was 89.2%, suggesting that smoking is one of the main causes of pulmonary heart disease.
