Most heart attacks are caused by coronary-artery disease, which occurs when a blood clot blocks blood and oxygen flow in a blood vessel leading to the heart. 大多数的心脏病发生原因都是由于血栓堵塞了心脏供血和氧的血管而引发的冠脉疾病。
Anti-platelet drugs have an "anti-clotting" effect and long-term low doses may prevent heart attacks and blood clot formation in people at high risk for developing blood clots. 在易血栓形成的高危人群中,抗血小板药有抗凝作用,长期低剂量使用可能可以预防心脏事件和血栓形成。
Myocardial infarction ( or myocardial infarction): Death of a section of heart muscle when its blood supply is cut off, usually by a blood clot in a coronary artery narrowed by atherosclerosis. 心肌梗塞:一部分心脏肌肉因其血液供应中断而死亡,通常是动脉硬化造成冠状动脉狭窄处形成血栓。
STEMI is a severe type of heart attack in which an artery is generally completely blocked by blood clot for sufficient time causing heart muscle damage. STEMI是一种严重的心脏病,这种疾病表现为动脉通常完全被血栓所堵塞,累积足够长时间可导致心脏肌肉损坏。
