摘要:

目的 探讨非ST段抬高型急性冠脉综合征(NSTE-ACS)患者经皮冠状动脉介入治疗(PCI)后碘对比剂(ICM)对甲状腺功能的影响及发生甲状腺功能减退的危险因素。方法 627例患者根据基线甲状腺激素水平分为甲状腺功能减退组(H组,62例)和甲状腺功能正常组(ET组,565例)。在PCI后1 d、1周、1个月、6个月监测患者甲状腺功能变化,多因素分析PCI前后患者发生甲状腺功能减退的危险因素。结果 2组促甲状腺激素(TSH)水平在PCI后1 d、1周均显著升高(均P<0.05),ET组在6个月时仍然高于基线水平(均P<0.05)。在6个月时,H组62例中43例仍为甲状腺功能减退状态;ET组发生ICM诱发性甲状腺功能减退133例(23.9%),至6个月时34例仍为甲状腺功能减退,发生碘诱导性甲状腺功能亢进事件4例。ICM后发生甲状腺功能减退的风险因素与发生基线甲状腺功能减退的独立危险因素并不完全一致。ICM用量是预测PCI后患者远期发生甲状腺功能减退的可靠工具(曲线下面积为0.674),其最佳阈值为190 mL。结论 NSTE-ACS患者在ICM暴露后发展为显性甲状腺功能减退的风险较低,将ICM暴露后6个月作为研究评估的时间窗可能会掩盖一些延长的ICM诱导性甲状腺功能不全事件。

Abstract:

Objective To explore the effect of iodine contrast media (ICM) on thyroid function and the risk factors of hypothyroidism in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS) after percutaneous coronary intervention (PCI). Methods According to the baseline thyroid stimulating hormone (TSH) level, 627 patients were divided into the hypothyroidism group (group H, n=62) and the euthyroid group (group ET, n=565). Changes of thyroid function were monitored at 1 day, 1 week, 1 month and 6 months after PCI, and the risk factors of hypothyroidism before and after PCI were analyzed by multivariate analysis. Results The levels of TSH increased significantly on the 1 day and 1 week after PCI in both groups (P<0.05), and group ET was still higher than its baseline value at 6 months (P<0.05). At 6 months, 43 of 62 cases in the group H were still in the state of hypothyroidism, but the event of overt hypothyroidism did not increase. In the group ET, there were 133 cases of ICM-induced hypothyroidism (23.9%), 34 cases of hypothyroidism and 4 cases of iodine-induced hyperthyroidism at 6 months. The independent predictors for hypothyroidism after ICM were not entirely consistent with the independent predictors for baseline hypothyroidism. The dosage of ICM was a reliable predictor for long-term hypothyroidism after PCI (AUC=0.674), and the best security threshold was 190 mL. Conclusion Patients with NSTE-ACS have a lower risk of developing overt hypothyroidism after ICM exposure. Taking 6 months after ICM exposure as a time window for study evaluation may mask some events of prolonged ICM-induced thyroid insufficiency.
