  德国一项前瞻性多中心研究显示,应激性心肌病(SC)的临床特点较既往所报告的更为广泛,临床症状初发时的心血管磁共振成像(CMR)结果可提供相关功能和结构信息,可能有助于诊断SC。

  该研究纳入欧洲和北美7个三级医疗中心的256例SC患者,结果显示,其中81%为绝经后女性,8%为年轻女性(≤50岁),11%为男性;182例(71%)患者存在压力应激。239例患者的CMR结果显示4种心室球样扩张:心尖部(82%)、双心室(34%)、心室中部(17%)和基底部(1%)。所有患者左室射血分数均减低(平均48%)。根据特定标准,CMR可准确诊断SC:典型左室功能不全、心肌水肿、无明显坏死/纤维化及存在心肌炎症标志物。随访期间CMR显示,所有患者左室射血分数完全正常(66%),无明显纤维化区域存在炎症标志物。
