The pathophysiology of Takotsubo cardiomyopathy remains unclear, but it has been suggested that the stress related neurohumoral factors, especially catecholamines, play an important role. Recently, several reports have described an inverted Takotsubo cardiomyopathy, which is characterized by the dysfunction of the basal and mid-ventricular segments sparing the apex of the heart. In this report, we present a case of a 50-year-old female with a transient left ventricular dysfunction in an inverted Takotsubo pattern, that later was diagnosed as a malignant pheochromocytoma.

고찰 1991년일본에서 Dote 등 [14] 에의해 Takotsubo 양좌심실기능부전 이라는가역적인심근병증이처음보고된이래, 2001년이후일본이외의지역에서 Dote 등 [14] 이보고한질환과같은질환이면서 일과성심첨부확장, 스트레스유발성심근병증 등의다른명칭으로불리는질환의보고가증가되면서이질환에대한관심이높아졌다 [11,15].

이러한 Takotsubo 심근병증은심근경색과비슷한임상양상을보이나, 관상동맥조영술에서설명할만한관상동맥의협착및연축 (spasm) 이관찰되지않고수주이내에 회복되는비교적양호한경과를보이는질환으로알려져있다 [17].

Takotsubo 심근병증은심초음파또는좌심실조영술시심첨부의확장으로인해좌심실의모양이일본에서사용하는문어잡이단지를뜻하는단어인 Takotsubo 와그모양이비슷하다고하여명명된심근병증이다 [16]. 이러한 Takotsubo 심근병증은심근경색과비슷한임상양상을보이나, 관상동맥조영술에서설명할만한관상동맥의협착및연축 (spasm) 이관찰되지않고수주이내에 회복되는비교적양호한경과를보이는질환으로알려져있다 [17]. Takotsubo Cardiomyopathy Study Group에서는 Takotsubo 심근병증진단지침을제시하고있는데 [17], 정의상으로는급성좌심실심첨부확장으로인해좌심실이 Takotsubo 라는일본의문어잡이단지와비슷한모양을보이고, 1개월이내에대부분완전히호전되는경과를보이는질환이다. 하지만분명한관상동맥병변이있거나, 뇌혈관이상, 갈색세포종또는심근염등이있을경우 Takotsubo 심근병증의진단에서제외할것을추천하며, 이중뇌혈관이상과갈색세포종에서유사한현상을보일경우 Takotsubo 양 (like) 심근병증 으로진단할것을제시하고있다. Takotsubo 심근병증의발병기전은정확히밝혀진바는없으나, 몇가지가설이제기되고있는데, 1) 관상동맥의다발성혈관수축, 2) 관상동맥미세혈관의부전, 3) 카테콜라민심장독성, 그리고 4) 신경학적기절심근등이다 [12]. Wittstein 등 [16] 은 13명의심첨부확장을보이는스트레스유발성심근병증환자와 7명의급성심근경색환자들의입원시카테콜라민수치를비교하였고, 에피네프린과노르에피네프린모두스트레스유발성심근병증환자들에서심근경색

6 Takotsubo-like Cardiomyopathy caused by Pheochromocytoma 103 증후군의심환자중 Takotsubo 심근병증으로진단된환자를대상으로전형적, 비전형적 Takotsubo 심근병증의빈도와기전, 예후에대해전향적분석을시행하였고, 35명의 Takotsubo 심근병증환자중 22명 (60%) 이전형적, 13명 (40%) 이비전형적유형을보였다고보고한바있다. garwal 등 [5] 은현재까지갈색세포종에서 Takotsubo 양심근병증이동반된환자들과 primary Takotsubo 심근병증환자들의유사점과차이점에대한분석을위해, 254건의 primary Takotsubo 심근병증환자와 38건의갈색세포종 -동반 Takotsubo 양심근병증환자의증례보고를분석하였다. 갈색세포종 -동반 Takotsubo 양심근병증환자중 23건 (60.5%) 에서전형적인심첨부확장을보였고, 12건 (31.5%) 이역위된 Takotsubo 양심근병증으로나타났다. 이러한결과는 primary Takotsubo 심근병증에서전형적, 비전형적유형과유사한비율이었다. 또한갈색세포종에서전형적및비전형적 Takotsubo 양심근병증이동반된환자들을비교한결과비전형적 Takotsubo 양심근병증환자에서전형적 Takotsubo 양심근병증에비해남성의유병률이다소높은경향을보였고심전도소견에서도 ST 분절의하강이비교적흔하였다. 합병증측면에서도비전형적 Takotsubo 양심근병증환자에서심인성쇼크 (66.7% vs. 17.4%) 와신부전 (25% vs. 0%) 의발생이유의하게높았고, 승압제의사용 (66.7% vs. 8.7%) 및대동맥내풍선펌프 (intra-aortic balloon pump) 사용 (33.3% vs. 4.3%) 이필요한경우가유의하게많았다. 하지만사망률에서는특별한차이없이오히려전형적 Takotsubo 양심근병증환자에서사망이보고되어, 질병의예후적측면에서는뚜렷한차이를보이지않았다 [5]. 현재까지우리나라에서보고된갈색세포종에서 Takotsubo 양심근병증이동반된증례는본증례를포함하여총 9건으로임상적인특징은 Table 2와같다 [6-10,20]. 아직보고된증례의수가적지만, 일반적으로 primary Takotsubo 심근병증이여성에서흔하고전형적인형태가많은것에비해 [15], 우리나라에서보고된갈색세포종동반 Takotsubo 양심근병증에서는남성에서의발병이흔하였고역위된형태가많았다. 또한 garwal 등 [5] 의보고에서갈색세포종동반 Takotsubo 양심근병증에서도전형적형태가많았던것과달리, 우리나라에서는역위된 Takotsubo 양심근병증의발생이흔하였고, 추적검사에서대체적으로가역적이며양호한결과를보였다. 최근의연구에서는교감신경및 adrenoceptor 의분포차이및생리적농도와독성농도에서의카테콜라민에대한 adrenoceptor 의반응차이등으로심실벽운동이상의다양성을설명하려는시도가있으나아직정립된가설은없다 [2,12]. 따라서향후이러한과도한교감신경항진에대한심실의반응및심실벽운동이상의차이에대한추가적인연구가이루어질필요가있다. 또한현재까지우리나라에서보고된증례들에서역위된형태가흔한것에대한분자생물학적인측면의연구뿐만아니라, 나아가역위된형태의 Takotsubo 심근병증과전형적형태의 Takotsubo 심근병증으로발현되는경우의 임상경과및예후등에대한주의깊은관찰이필요할것으로생각 된다. 본증례는급성폐부종을동반한역위된 Takotsubo 양심근병증 및발작성심실상성부정맥으로표현된환자에서추후에악성갈색 세포종이진단되었던경우로, Takotsubo 양심근병증은갈색세포종 에드물게동반될수있다. 특히고혈압및심계항진등의비교적흔 한동반증상이없이심근병증으로발현한경우진단이어려울수 있지만, 정확한진단및치료를통해완치를기대할수있는질환이 다. 따라서비교적젊은나이에특별한기저질환및설명할만한원 인이없는가역적심부전증상을보일경우감별진단에반드시갈색 세포종을고려할필요가있다. 요약 저자들은흉통을주소로내원한 50 세여자환자가역위된 Takotsubo 심근병증을진단받고대증적치료후호전되어퇴원하였다가 추후에갈색세포종이진단된 1 예를경험하였다. 현재까지우리나라 에서보고된갈색세포종동반 Takotsubo 양심근병증증례는전세 계적으로보고된증례와비교하여남성이더많았고, 대부분역위된 Takotsubo 양심근병증형태를보였다. 본증례또한그동안의우리 나라에서보고된증례와유사한임상양상을보였다. Takotsubo 양 심근병증은갈색세포종에서드물게동반되는질환이지만, 갈색세포 종에대한치료를통해교정가능한질환이라는점에서원인불명의 심부전을보이는환자에서감별할필요가있다고생각되어문헌고 찰과함께보고하는바이다. 참고문헌 1. Sica D: Endocrine causes of secondary hypertension.
