JAHA:心脏结节病和特发性巨细胞心肌炎的临床表现和结局比较

2021-03-04 MedSci原创 MedSci原创

GCM与CS的不同之处在于,它具有更广泛的心肌损伤和较差的患者预后。然而,患者预后的关键决定因素似乎是心肌损伤的程度,而不是组织病理学诊断。

心脏结节病(CS)和巨细胞心肌炎(GCM)具有许多相似的组织病理学和临床特征。它们是否是某一种疾病的一部分目前仍无定论。

近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员比较了自1980年代末以来直至2018年2月期间351例CS病例和28例GCM病例的医疗记录数据,他们发生了心脏死亡、猝死和心脏移植的复合终点。

GCM和CS患者出现心力衰竭表现的比例分别为50% vs. 15%(P<0.001),高级房室传导阻滞分别为21% vs. 43%(P=0.044)。就目前而言,81%的GCM病例中左心室射血分数≤50%,而在CS病例中则为48%(P=0.004)。GCM病例入院时血浆B型利钠肽前体N末端(NT-proBNP)的中位数(四分位数范围)为5273(2782-11309)ng/L,而CS病例为859(290-1950)ng/L(P<0.001),而19例GCM病例中有17例患者心脏肌钙蛋白T超过50 ng/L,而239例CS病例中有48例患者心脏肌钙蛋白T超过50 ng/L(P<0.001)。

CS病例5年无事件生存率估计为77%(95%CI为72%–82%),而在GCM病例中为27%(95%CI为10%–45%)(P<0.001)。通过Cox回归分析,GCM病例预测的心脏事件危险比为5.16(95%CI为2.82–9.45),但是在纳入心肌损伤和功能障碍标志物后,风险比降低至1.58(95%CI为0.71-3.52)。

由此可见,GCM与CS的不同之处在于,它具有更广泛的心肌损伤和较差的患者预后。然而,患者预后的关键决定因素似乎是心肌损伤的程度,而不是组织病理学诊断
