Simultaneous anterior, inferior, and right ventricular ST-segment elevation myocardial infarction is an unusual condition. A 50-year-old male patient presented with severe, squeezing chest pain of an hour onset. ST-segment elevations were detected in all precordial derivations, DII, DIII, aVF and V3R, V4R. Coronary angiography showed a significant lesion in the left anterior descending (LAD) coronary artery, just below the second diagonal branch. Balloon predilatation was performed after 40 minutes of admission, followed by bare metal stent implantation, which resulted in ST-segment resolution in all leads and relief of chest pain. Echocardiography showed dyskinesia of the left ventricular apical wall, and hypokinesia of the interventricular septum and inferior wall. Left ventricular ejection fraction was 40%. Coronary angiography and cardiac CT angiography demonstrated a wrapped LAD. The patient was discharged five days after percutaneous coronary intervention (PCI) with stabilization of his clinical status. Ten days after PCI, he presented with chest pain associated with left ventricular anterior and inferior reinfarction. Successful balloon dilatation was performed for thrombotic in-stent restenosis. His clinical condition improved and he was asymptomatic for a month, during which no signs of deterioration were observed in electrocardiographic and echocardiographic findings.
同时发生前壁、下壁及右心室ST段抬高型心肌梗死是一种不常见的情况。一名50岁男性患者出现起病1小时的严重压榨性胸痛。所有胸前导联、Ⅱ、Ⅲ、aVF及V3R、V4R导联均检测到ST段抬高。冠状动脉造影显示左前降支(LAD)冠状动脉在第二对角支下方有明显病变。入院40分钟后进行球囊预扩张,随后植入裸金属支架,所有导联ST段恢复正常,胸痛缓解。超声心动图显示左心室心尖壁运动障碍,室间隔及下壁运动减弱。左心室射血分数为40%。冠状动脉造影及心脏CT血管造影显示LAD呈包绕状。患者在经皮冠状动脉介入治疗(PCI)后5天出院,临床状况稳定。PCI术后10天,他出现与左心室前壁及下壁再梗死相关的胸痛。对支架内血栓形成性再狭窄成功进行了球囊扩张。他的临床状况改善,1个月内无症状,在此期间心电图和超声心动图检查未发现恶化迹象。
