Ticagrelor (BRILINTA®) is a very commonly used oral antiplatelet agent in acute coronary syndrome and after percutaneous coronary intervention (PCI). It is a reversible, direct inhibitor of the adenosine diphosphate (ADP) P2Y12 receptor. Most of the patients tolerate the drug well but it is known to cause brady arrhythmias and ventricular pauses, the exact mechanism of which is unclear. We present a case of acute coronary syndrome/unstable angina in a 58-year-old Caucasian gentleman requiring cardiac catheterization and PCI with drug eluting stent deployment and syncope following Ticagrelor loading from long ventricular pauses.
替格瑞洛(倍林达®)是急性冠状动脉综合征及经皮冠状动脉介入治疗(PCI)后常用的口服抗血小板药物。它是一种可逆的二磷酸腺苷(ADP)P2Y12受体直接抑制剂。大多数患者对该药耐受性良好,但已知其会引起缓慢性心律失常和心室停搏,确切机制尚不清楚。我们报告一例58岁白种男性急性冠状动脉综合征/不稳定型心绞痛患者,该患者需要进行心脏导管插入术及植入药物洗脱支架的PCI治疗,在替格瑞洛负荷给药后因长时间心室停搏出现晕厥。
