An observational study was conducted of participants in a 4-km race with the object of identifying risk factors for a poor outcome. Sixteen individuals were identified who required medical assistance at the end of the race. Pulse and lying and standing blood pressure were measured and a brief history was taken. Compared with 92 controls, the subjects showed a greater orthostatic drop in systolic blood pressure and were more likely to have consumed alcohol in the preceding 24 h.
为了确定导致不良结果的风险因素,对参加4公里赛跑的参与者进行了一项观察性研究。研究发现16名个体在比赛结束时需要医疗救助。测量了他们的脉搏、卧位和立位血压,并采集了简要病史。与92名对照组相比,这些受试者的收缩压体位性下降幅度更大,并且在前24小时内饮酒的可能性更高。
