Cocaine toxicity can result in myocardial infarction from coronary vasospasm. The current treatment algorithm includes intravenous and/or intracoronary vasodilator administration with an expectantly quick resolution of symptoms and signs of ischemia. However, in situations in which myocardial injury persists, the optimal management is uncertain. We present a case in which extracorporeal membrane oxygenation effectively stabilized a patient with ongoing hemodynamic instability who experienced repeated episodes of myocardial injury and ventricular tachyarrhythmias due to cocaine toxicity. < In many urban settings, cocaine-induced angina is not uncommon. The pathogenesis of its manifestation includes coronary artery vasospasm and decreased left ventricular function. Treatment typically involves systemic vasodilators, such as nitrates and calcium channel blockers. However, in patients with substantial hemodynamic instability, these agents might result in a worsening of systemic perfusion. Accordingly, extracorporeal membrane oxygenation should be considered in such cases to promote myocardial recovery.>.
可卡因中毒可导致冠状动脉痉挛引起心肌梗死。目前的治疗方案包括静脉内和/或冠状动脉内给予血管扩张剂,以期症状和缺血体征迅速缓解。然而,在心肌损伤持续存在的情况下,最佳治疗方案尚不确定。我们报告一例病例,体外膜肺氧合有效地稳定了一名因可卡因中毒而反复出现心肌损伤和室性快速心律失常且血流动力学持续不稳定的患者。<在许多城市环境中,可卡因诱发的心绞痛并不罕见。其表现的发病机制包括冠状动脉痉挛和左心室功能下降。治疗通常涉及使用全身性血管扩张剂,如硝酸盐和钙通道阻滞剂。然而,对于血流动力学严重不稳定的患者,这些药物可能会导致全身灌注恶化。因此,在这种情况下应考虑使用体外膜肺氧合来促进心肌恢复。>
