Takotsubo cardiomyopathy is usually caused by triggering stress. It has 4 different subtypes. There has been no consensus to differentiate various types with regard to characteristics of the patient population. The goal of this study was to evaluate any clinical differences between the reverse type in comparison to common apical and mid-cavitary types using case series of reported cases. The authors searched published articles in PubMed and Medline on takotsubo or stress-induced cardiomyopathy. They included only cases that reported different types of takotsubo cardiomyopathy with baseline clinical characteristics. They identified 60 patients for the final analysis. The types of takotsubo cardiomyopathy seen in this study are classified as classic (66.7%), mid-cavitary (10%), or reverse (inverted) (23.3%). Patients with reverse-type takotsubo cardiomyopathy were significantly younger compared with those with other types (mean age, 36 for reverse vs 62 for other types; P<.001). Furthermore, all patients with the reverse type had physical or mental stress, whereas those with other types had no triggering stress in 02% of the reported cases (P<.0001). Among patients presenting with takotsubo cardiomyopathy, the reverse or inverted variant presents at a younger age and is always associated with a triggering of emotional or physical stress.
应激性心肌病通常由触发应激引起。它有4种不同亚型。关于如何根据患者群体特征区分不同类型,目前尚无共识。本研究的目的是通过已报道病例的病例系列,评估反向型与常见心尖型和心腔中部型之间的任何临床差异。作者在PubMed和Medline上搜索了关于应激性心肌病或应激性心肌病的已发表文章。他们只纳入了报告了具有基线临床特征的不同类型应激性心肌病的病例。他们确定了60例患者进行最终分析。本研究中观察到的应激性心肌病类型分为经典型(66.7%)、心腔中部型(10%)或反向(倒置)型(23.3%)。与其他类型患者相比,反向型应激性心肌病患者明显更年轻(平均年龄,反向型为36岁,其他类型为62岁;P<0.001)。此外,所有反向型患者都有身体或精神应激,而其他类型患者在02%的报告病例中没有触发应激(P<0.0001)。在患有应激性心肌病的患者中,反向或倒置变体发病年龄较轻,且总是与情绪或身体应激的触发有关。
