院外获得性肺炎较为常见,且死亡风险也不低,尤其在老年人群中也易并发心血管事件(CVEs);而抗炎治疗无疑能改善其预后。既往关于长期服用阿斯匹林能否降低尤其是老年人肺炎的死亡风险尚不清楚,现就此进行相关对照研究。受测对象为1 005例老年患者,基线均龄(74.7±15.1)岁,男性居多,且均为罹患肺炎老年患者。其中长期服用阿斯匹林 Extra-hospital acquired pneumonia is more common, and the risk of death is not low, especially in the elderly are also complicated by cardiovascular events (CVEs); and anti-inflammatory treatment will undoubtedly improve its prognosis. Whether the long-term use of aspirin can reduce the risk of death, especially in elderly pneumonia, is unclear. Therefore, a related controlled study has been carried out. The subjects were 1,005 elderly patients, mean age (74.7 ± 15.1) years old, mostly male, and are elderly patients suffering from pneumonia. Among them aspirin long-term use
