Number seven. Clots. People who spend long hours working on a computer, face the risk of developing a condition called deep vein thrombosis (DVT).

血液凝块。长时间在电脑上工作的人患深静脉血形成（DVT）。

Also, though, blood thinners can be prescribed instead if someone has an abnormal heart rhythm like atrial fibrillation, since clots are more likely to occur in the heart and travel to the brain.

如果患者有房颤等心律失常时，也可以用抗凝剂代替，因为在这些患者中，血在心脏形成并播散至脑部。

Finally, with protein C or S deficiency, there can be warfarin induced skin necrosis, which means tiny thrombi can form in the blood vessels of the skin, causing skin necrosis.

Researchers believe as our bodies fight the disease, inflammation and plaque in our arteries become more unstable and may form clots and blockages.

It will then be packed in ice and injected with heparin, an anticoagulant, to prevent blood clots.

然后将其放入冰块中，注射肝素（一种抗凝剂）以防止血形成。

It causes arterial and venous thrombosis.

它会导致动脉和静脉血形成。

These changes make the endothelial lining more likely to develop blood clots or aneurysms.

这些变化使得内皮细胞内壁更形成血或动脉瘤。

This increases circulating factor V and factor VIII levels, and " tips the scale" toward coagulation, putting them at increased risk for thrombosis, or developing blood clots.

这使得血液循环中V因子和VIII因子数量增多，更发生凝血，导致血形成的风险增加。

For medications, daily aspirin can be used to reduce the chance that a blood clot will form in the future.

药物方面，每天服用阿司匹林能减少血形成的风险。

But sometimes, the increased pressure in the vein can cause a part of the main clot to break free, becoming an embolus which can travel downstream towards the heart.

但有时候，随着静脉压增加，一部分血可以脱落下来形成血子，并且随着血流到达心脏。

When the risk of blood clots is high, therapy usually involves lowering the platelet count by using medications like hydroxyurea, interferon-alpha, and anagrelide.

当血形成风险较高时，治疗常包括用羟基脲、α干扰素和阿那格雷等药物来降低血小板计数。

Five years in, the chance of a clot forming dramatically declines, and the risk of stroke continues to reduce.

五年内，血形成的几率大大下降，中风风险持续减少。

Now, all of these excess platelets end up causing an increased risk of blood clots in the deep veins of the legs, lungs, and even sites where clots don't usually form, like the abdomen.

这些过量的血小板最终会使腿部、肺部深静脉，甚至一些不常有血的部位如腹部，形成血的风险增加。

That's when a clot forms, usually in the deep veins of the leg, and then parts of the clot can break off and travel to other parts of the body.

血形成时，一般发生在腿部深静脉，血的一部分可能脱落并到达身体其他部位。

For young and healthy patients who are at low risk of blood clots or bleeding, sometimes we give aspirin and monitor the platelet counts.

对于血形成或出血风险较低的年轻、健全患者，可以用阿司匹林并监测血小板计数。

And then hypertension is another risk factor for developing clots and arterial disease.

然后，高血压是形成血和动脉疾病的另一个风险因素。

Treatment of essential thrombocythemia depends on risk of blood clots.

原发性血小板增多症的治疗取决于血形成的风险。

On one side you have thrombosis, which is when clots obstruct the vessel, and at the same time you have trouble forming clots, which leads to bleeding.

一方面存在血凝块血管的血形成，同时又存在导致出血的血凝块形成障碍。

This cascade has a great degree of amplification and takes only a few minutes from injury to clot formation.

这种级联反应有大幅的扩大效应，从血管壁受损到血形成只需要几分钟。
