Those who had COVID-19 at risk of developing blood clots: Singapore scientists

Those who have recovered from COVID-19 could be at risk of developing blood clots, Singapore scientists found.  

A study based on blood samples collected from 30 recovered COVID-19 patients have shown signs of blood vessel damage that may have been caused by the patients’ active immune systems. According to the study, those with pre-existing cardiovascular conditions were at a higher risk of developing blood clots. 

“The researchers hypothesise that the body’s immune system, which was activated to fight the COVID-19 virus, remains overactive and activated even after recovery,” a statement released by the Nanyang Technological University said.

“This persistently activated immune responses may attack blood vessels of recovered COVID-19 patients, causing even more damage and increasing the risk of blood clot formation further.” 

The study involved scientists from the Nanyang Technological University, the Agency for Science, Technology and Research, and the National Centre of Infectious Diseases. 

The blood samples were taken from patients a month after they recovered and discharged from the hospital. NTU said that those samples had contained twice the number of cells that had been detached from injured blood vessels.

Singapore has reported 60,678 coronavirus cases and 30 deaths. 

那些患有COVID-19的人有形成血栓的风险：新加坡科学家

新加坡科学家发现，那些从COVID-19中恢复的人可能有血栓形成的风险。  

根据从30名康复的COVID-19患者中收集的血液样本进行的研究表明，血管损伤的迹象可能是患者的主动免疫系统引起的。根据这项研究，那些患有心血管疾病的人发生血栓的风险更高。 

南洋理工大学发表的一份声明说：“研究人员假设，为抵抗COVID-19病毒而被激活的人体免疫系统，即使恢复后仍保持过度活跃和被激活的状态。”

“这种持续激活的免疫反应可能会攻击已康复的COVID-19患者的血管，造成更大的损害，并进一步增加形成血块的风险。” 

该研究涉及南洋理工大学，科学技术和研究机构以及国家传染病中心的科学家。 

在患者康复并出院一个月后，从患者那里采集血液样本。NTU说，这些样品所含的细胞数量是受伤血管中分离细胞的两倍。

新加坡报告了60,678例冠状病毒病例和30例死亡。
