研究检查血凝块后的长期结果

根据一份报告，在其腿部（肺静脉血栓形成）或肺部（肺栓塞）或肺部（肺栓塞）面临血凝块的患者有风险，患有肺栓塞的患者具有更高的死亡风险，请介绍2月25日问题内科档案。

根据物品的背景信息，深静脉血栓形成和肺栓塞被认为是相同疾病过程的不同表现。作者说，这两个条件的医疗管理统称为静脉血栓栓塞，在过去十年里有所改善。

Of those, 549 had pulmonary embolism and 1,142 had isolated deep vein thrombosis.

在为期三年的研究中，在患有肺栓塞的549名患者中，31例（5.7％）在肺部有复发凝块，75例（13.7％）复发出一种类型的静脉血栓栓塞和82（14.9％）experienced a major bleeding episode (i.e., so severe they required a transfusion). Among the 1,142 patients who presented with isolated deep vein thrombosis over the same period, 64 (5.6 percent) developed a pulmonary embolism, 217 (19 percent) had recurrent venous thromboembolism and 146 (12.8 percent) had a major bleeding episode.

一个月后，患有肺栓塞的个体更可能死亡（比5.4％的13％），一年（26％与20.3％）和三年（35.3％与29.6％）比具有深静脉血栓形成的人。“当作者写道，”当作者来说，“课程被重大出血的患者更容易经历复发静脉血栓栓塞或在三年内死亡。
