冠状动脉粥样硬化斑块的破裂和轻微狭窄是急性冠状动脉血栓形成和心肌梗死的常见诱因。本文对动脉血栓形成的发病机制、局部动脉壁基质、血流流变学、全身因素以及凝血酶在血栓形成中的重要作用进行了讨论。更有效的抗血栓治疗可以加速外源性血栓溶解,允许内源性血栓溶解,并应减少复发性梗死和缺血和死亡,以及冠状动脉血运重建的需要。急性心肌梗死的最大抗血栓治疗包括静脉推注100 U/kg肝素,随后静脉输注-体重60-80 kg的患者为1,200 U/hr,体重>80 kg的患者为1,300 U/hr,对于体重< 60 kg(或17 U/kg/hr)的受试者,以000 U/hr的速率给药,以将活化部分凝血活酶时间维持在对照组的2-3倍(60-90秒),持续至少5-7天。为了将静脉内给药转换为皮下给药,每12小时使用14,000 - 17,000 U,最初与静脉输注重叠2小时。入院时阿司匹林的负荷剂量为160 mg,随后为80 mg/天。高危患者应考虑将肝素转换为华法林治疗至少3个月,国际标准化比值为2.5-4.0,以预防复发性缺血、再梗死、死亡、血栓栓塞、血栓形成再激活和减少血运重建的必要性。
Disruption of an atherosclerotic plaque in coronary arteries with a minor stenosis is the usual stimulus for acute coronary thrombosis and myocardial infarction. In this article the pathogenesis of arterial thrombosis and contributions of local arterial wall substrates, the rheology of blood flow, systemic factors, and the critical role of thrombin in the formation of thrombus are discussed. More potent antithrombotic therapy may accelerate exogenous thrombolysis, allows endogenous thrombolysis, and should reduce recurrent infarction and ischemia and death, as well as need for coronary revascularization. Maximal antithrombotic therapy for acute myocardial infarction includes an intravenous bolus of heparin at 100 U/kg followed by an intravenous infusion—at 1,200 U/hr for patients weighing 60–80 kg, 1,300 U/hr for those weighing >80 kg, and 1,000 U/hr for those weighing < 60 kg (or 17 U/kg/hr)—to maintain the activated partial thromboplastin time at 2–3 times control (60–90 sec) for at least 5–7 days. To convert intravenous to subcutaneous administration, use 14,000–17,000 U every 12 hours and initially overlap the intravenous infusion by 2 hours. The loading dose of aspirin on admission to the hospital is 160 mg followed by 80 mg/day. High-risk patients should be considered for conversion of heparin to warfarin therapy for at least 3 months at an international normalized ratio of 2.5–4.0 for the prevention of recurrent ischemia, reinfarction, death, thromboembolism, reactivation of thrombosis, and reduced necessity for revascularization.
