Abstract

We present a rare case of a 77-year-old Italian woman, admitted to the neurology unit with the diagnosis of West Nile virus encephalitis. Twenty days after the onset of the neurological symptoms, new negative T-waves appeared on the ECG in association with serum elevation of myocardial necrosis enzymes and regional cardiac wall motion abnormalities on echocardiography, so that a coronary angiography was performed. The exam showed significant stenosis on the left circumflex artery, treated with percutaneous coronary intervention. In addition, a cardiovascular magnetic resonance was performed for further investigation: the T2-weighted images revealed edema in the anterior wall and mid-wall late gadolinium enhancement, significant findings of acute myocardial inflammation. Because of the recent diagnosis of West Nile virus encephalitis and the high serum level of specific IgM antibody, the clinical presentation was suggestive of West Nile myocarditis.

[西尼罗河病毒与心肌炎,罕见事件:病例报告]。
我们报告了一例罕见的77岁意大利妇女,她被诊断为西尼罗河病毒性脑炎,住进了神经科。神经系统症状出现20天后,心电图上出现新的阴性T波,与血清心肌坏死酶升高和超声心动图上的局部心壁运动异常有关,因此进行了冠状动脉造影。检查显示旋左动脉明显狭窄,经皮冠状动脉介入治疗。此外,还进行了心血管磁共振检查以进行进一步研究:T2加权图像显示前壁和中壁水肿,钆增强晚期,这是急性心肌炎症的重要表现。由于最近诊断为西尼罗河病毒性脑炎,且血清特异性IgM抗体水平高,临床表现提示为西尼罗河心肌炎。
