The power of four cardiorespiratory symptoms to predict subsequent mortality has been analysed in data derived from a random sample of the population of Great Britain recruited in 1965 and followed for 12.4 years. The associations of respiratory symptoms with all causes of death (except stroke) and of cardiovascular symptoms with death from coronary heart disease were strong. The trends of these two associations over the 12.4 years of the follow-up differed substantially: the relative death rates associated with respiratory symptoms remained throughout at about the same level, while those associated with cardiovascular symptoms declined after four years. The excess premature deaths associated with presence of one or more symptoms at entry represented about a quarter of the observed deaths of men and one tenth of those of women.
对1965年从英国人口中随机抽取的样本数据进行了分析,以研究四种心肺症状预测后续死亡率的能力,随访时间为12.4年。呼吸系统症状与所有死因(中风除外)之间的关联以及心血管系统症状与冠心病死亡之间的关联都很强。在12.4年的随访中,这两种关联的趋势有很大差异:与呼吸系统症状相关的相对死亡率在整个随访期间基本保持在同一水平,而与心血管系统症状相关的相对死亡率在四年后下降。入组时存在一种或多种症状导致的过早死亡超额数约占男性观察到的死亡人数的四分之一和女性的十分之一。
