The aim of the present study was to examine the impact of the menopause in middle-aged Korean females with acute myocardial infarction (AMI). Methods: A total of 1,781 middle-aged females (aged < 65 years) in the Korean Acute Myocardial Infarction registry were enrolled into this study between November 2005 and December The patients were divided into two groups; the pre-menopause group ( 55 years old) and the menopause group (56-64 years old). Major adverse cardiac events (MACE) were analyzed over a one-year follow-up period. Results: The pre-menopause and menopause groups comprised 669 patients (mean age, 49.1 ± 5.6 years) and 1,112 patients (mean age, 60.6 ± 2.6 years), respectively. The incidence of hypertension (42.2% vs. 59.4%, p < 0.001), diabetes mellitus (DM) (27.4% vs. 35.7%, p < 0.001), and dyslipidemia (12.9% vs. 17.7%, p = 0.008) were more frequent in menopausal patients.

2 - Mi Sook Oh, et al. Menopause in acute myocardial infarction - rates of smoking (20% vs. 12.7%, p < 0.001) and familial history (12% vs. 6.8%, p < 0.001) were higher in the pre-menopause group. The cumulative rates of MACE did not show any differences between the two groups. A history of atrial fibrillation, previous AMI and DM, higher Killip class, and multi-vessel disease were independent risk factors for predicting one-year MACE. Conclusions: The survival analysis demonstrated that there was no significant difference in MACE rates between the pre-menopause and menopause groups during the one-year follow-up. Therefore, middle-aged pre-menopausal women should be treated more intensively, regardless of whether they are menopausal. (Korean J Med 2016;91: ) Keywords: Menopause; Myocardial infarction; Prognosis 서론오늘날현대인들의생활수준이향상되면서활동량은줄어들고영양섭취량은많아지면서질병양상이급성질환에서고혈압, 당뇨병, 고지혈증등만성질환의증가로변화하였다 [1]. 한국인에서사망의원인도변화하고있다. 악성신생물이높은순위를차지하고있지만단일기관으로인한사망률로볼때는심뇌혈관질환이빠른속도로증가하고있다 [2]. 심혈관질환의유병률은여성보다남성의유병률이대체로높지만중년이후에서는여성의유병률이높아지고있다 [3]. 2013년고혈압학회에서발표한질병관리본부의조사내용에서는고혈압유병률이현저하게중년이후여성에서높아지는것을볼수있다 [1]. 한국인급성심근경색증등록사업 (Korea Acute Myocardial Infarction Registry, KAMIR) 에등록된데이터를분석한결과 6년동안한국여성의급성심근경색증의발생률은남성에비해서나이가들어갈수록증가되었으며, 그증가율이중년이후부터빠른속도로증가되는것을알수있었고 70대에가장높은것으로나타났다 [4]. 중년이후여성들의심혈관질환이증가하는데는폐경기를거치면서난소에서의에스트로겐의분비감소가원인이라는여러연구에서보고되었다 [5,6]. 대표적인연구결과로는난소에서분비되는에스트로겐호르몬은혈관에존재하는난포호르몬수용체를통해혈관내피세포와혈관의평활근세포에작용하여혈관을확장시키므로폐경후의에스트로겐분비감소는혈압상승의원인이된다 [7]. 그리고폐경후에는총콜레스테롤과저밀도지단백콜레스테롤이증가되면서고지혈증의발생으로동맥경화증이진행이급속히되고혈액응고인자인섬유소원의농도가증가되면서혈전증에대한위험이높아지고심혈관질환의이환율이높아지게된다 [8,9]. 여성들은폐경에의해서같은나이의남성보다심혈관질환의위험이증가하는데, 이는폐경여성의체질량지수 (body mass index, BMI), 체지방량, 지방분포의변화와에스트로겐호르몬의감소로기초대사량이감소하면서체중의증가로심혈관질환의위험을증가시킨다 [10]. 이연구의목적은폐경을기준으로폐경전심근경색증이발생한환자와폐경후심근경색증이발생한환자의임상적특징및예후를파악해보고폐경전후발생한심근경색증환자의치료및관리에중요한자료를제공하고자본연구를시행하였다. 대상및방법연구대상 2005년 11월부터 2013년도 12월까지 KAMIR 에등록된 세까지의 4,128명중심근경색증발생후 1년추적조사가된 1,781명중년여성으로폐경전여성 699명 (I군, 55세, 49.1 ± 5.6세 ) 과폐경후여성 1,112명 (II군, 세, 60.6 ± 2.6세 ) 을대상으로두군간의임상경과를비교분석하였다. 연구방법한국심장학회 50주년기념연구사업으로진행되었던 KAMIR 의환자정보기록를이용하였다 [11]. 전남대학병원생명윤리위원회의심의 (CNUH 05-49) 를통과하여모든환자의동의서취득후이루어졌다. 일반적특성으로는연령, 신장, 몸무게, BMI, 체중, 혈압, 맥박, Killip Class, 심방세동, 고혈압, 당뇨병, 이상지질혈증, 흡연, 가족력, 심근경색증기왕력, 심혈관사건, 최종진단명, 주요심장사건에대해조사하였다. 임상적특징으로는헤모글로빈, 혈당, 크레아티닌, creatine kinase (CK), CK-MB, Troponin-I, 총콜레스테롤, 중성지

6 - Mi Sook Oh, et al. Menopause in acute myocardial infarction - 았다 [3]. 특히여성은폐경을시작으로생리적, 생물학적변화가생기며관상동맥질환유병률이높아졌으며 [14], 폐경전에는관상동맥질환발생이매우드물었다 [15]. 같은연령군을비교해보았을때폐경이전여성보다폐경여성에서관상동맥질환발생위험이 4배에달하였다 [16]. 본연구에서또한중년여성에서폐경후여성이폐경전여성에비해심근경색증발생률이 3배정도높았다. 폐경발생에대한연령은연구마다차이가나타나고, 해마다증가하는양상을보였다. 1994년보고되었던한국여성의폐경연령은평균 48세였고 [17], 2001년보고에서는폐경연령이 49.2세로다소높아지는추세였다 [18]. 국외 cohort 연구에서폐경평균연령은 51.4세였으며 [19], 다민족을대상으로한 Study of Women s Health Across the Nation' 연구에서는폐경평균연령이 51.4 세였다. 특이한양상은일본여성이백인여성보다폐경평균연령이 51.8세로가장높았다 [20] 년까지 KAMIR에등록된환자의폐경전여성의평균연령은 50.4세로나타났다. 이결과를바탕으로 KAMIR 데이터의폐경연령은 50.4세보다더높아질것으로추정되어본연구에서는폐경연령을 55세기준으로정하였으며향후폐경연령에대한연구가더필요하다고생각된다. 여성은폐경기가되면에스트로겐호르몬이감소하고체력이급격히떨어지며여러가지생리적인변화가나타난다. 폐경이전의여성은항동맥경화증인자인고밀도지단백콜레스테롤의수치가남성보다높고, 저밀도지단백콜레스테롤의수치가낮게나타나지만, 폐경이후에는난포호르몬결핍에의한난소기능의저하로에스트로겐자극과저밀도지단백수용체활동의감소가이루어져저밀도지단백콜레스테롤이증가하고고밀도지단백콜레스테롤의수준이낮아져서 [21,22], 폐경기여성들의심혈관질환의유병률을증가시키는원인이된다 [23,24]. 폐경이후감소하는에스트로겐은관상동맥에서혈관을보호하는기전인저밀도지단백산화의억제, 콜레스테롤의혈관벽내유입억제, 혈관벽으로부터콜레스테롤유출증가, 혈관평활근세포및 myoinitial cell 의증식억제, collagen과 elastin 생성을억제, 혈소판의응집억제, prostacyclin의생성을증가시켜죽상동맥경화증의형성을억제할수있다 [25-27]. 폐경전여성에서도에스트로겐의수치가낮은여성은심혈관질환위험도가더높아짐을볼수있다. 본연구에서도폐경후군에서저밀도지단백콜레스테롤이높았다. 폐경여성에서에스트로겐호르몬치료를통해심혈관질 환발생이감소됨을볼수있었던결과 [28] 와폐경전여성에서도에스트로겐의수치가낮은여성은심혈관질환위험도가더높아짐을볼수있다 [29]. 그러나본연구에서는폐경전후두군간에급성심근경색증발생후일년간주요심혈관사건에는크게차이가없었다. 일반적으로폐경전후여성들은체중이점차증가하게되며, 체질량지수가증가하면혈압이증가하고체질량지수가 25 이상일때는콜레스테롤이높아지며저밀도지단백 / 고밀도지단백의비가증가되었다 [22]. 이러한변화는관상동맥질환의위험인자에해당이되므로과체중비만여성들에게는관리가중요하다 [22]. 본연구에서는폐경전과후에비만도는큰차이가없었으나폐경후여성에서는이상지혈증이더증가되는것을볼수있었으며, 이완기혈압은의미있게폐경후군에서높았다. 흡연과심혈관질환은밀접한관련이있으며, 흡연은폐경연령을앞당긴다는결과들이있다 [8]. 본연구에서도폐경전여성에서는흡연이급성심근경색증발생위험인자로써의미있는결과로분석되었다. 기존연구에서도폐경으로인한에스트로겐의부족, 흡연, 비만, 지단백의변화, 운동부족등은심혈관질환위험도를증가시키고심혈관질환으로인한사망과밀접한관련이있다는것을볼수있었다 [23,24]. 한국인젊은심근경색증환자중 40세전후양군을대상으로주요심장사건및 1년간무사건생존율을비교하였을때양군간의유의한통계적차이는없었으며 [30], 심근경색증으로내원한 75세이상의노인환자들을대상으로젊은대조군과주요심혈관사건의차이를 1년간추적한결과양군의유의한차이를보이지않았다 [31]. 본연구에서도폐경이급성심근경색증발생에영향을미치고발생후주요심혈관사건에서도폐경후중년여성에서더높을것이라고예측하였지만, 위의연구결과와같이양군간의유의한차이가없었다. 예측하건대의학의발달로다양한좋은치료약들과스텐트, 식이요법과운동에대한교육으로발생후관리가잘되고있는것으로보여진다. 하지만폐경전중년여성들의건강관리가부족한것으로보여지므로폐경전여성들에대한집중적인관리가필요하며, 장기간추적관찰의필요성이요구된다. 본연구의제한점은후향적이며폐경전그룹의표본수가폐경후군에비해적었다. 또한 KAMIR 에등록된다기관의대규모데이터를활용하여폐경의정확한연령을알수없었다는점이다. 여러가지문헌고찰을통해폐경으로인한에

7 - 대한내과학회지 : 제 91 권제 2 호통권제 672 호 스트로겐분비의감소가체중증가, 당뇨, 고혈압, 저밀도지단백콜레스테롤의증가등의여러가지변화를오게하는요인으로보여지고, 또한심혈관질환의위험요인들과밀접한관련이있는것으로사료된다. 그러나본연구는후향적연구로써폐경후여성호르몬요법등의치료여부에대한조사가되어있지않아서여성호르몬치료전후의차이를알수없었다, 향후폐경후여성의호르몬치료에대한자료를추가하여연구가더필요할거라생각된다. 본연구에서의제한점을보완하여장기간의임상적관찰을통해중년여성의심근경색증환자의효과적인치료와관리를위한기초자료를마련하고폐경전중년여성심근경색증환자의집중적인관리로예후를향상시킬수있는기초자료를마련하고자한다. 은두군간차이를나타내지않았다. 또한생존율과생존분석도두군간에유의한차이가없었다. 다변량분석을한결과당뇨병 (HR 1.69, 95% CI , p = 0.006), 심방세동 (HR 5.95, 95% CI , p = 0.007), 심근경색증기왕력 (HR 1.86, 95% CI , p = 0.009), 다혈관질환 (HR 1.54, 95% CI , p = 0.025) 그리고 Killip class (HR 1.26, 95% CI , p = 0.028), 가족력 (HR 1.78, 95% CI , p = 0.042) 은 1년주요심혈관사건을예측하는독립적인위험요인이었다. 결론 : 한국인중년여성심근경색증환자에서 1년간추적관찰결과생존분석과주요심혈관사건은폐경전후유의한차이가없었다. 따라서폐경전중년여성심근경색증환자도집중관리가필요할것으로생각된다. 요 약 중심단어 : 폐경 ; 심근경색증 ; 예후 목적 : 폐경은지질대사장애, 비만그리고혈전형성촉진과관련이있는것으로알려져있다. 본연구에서는한국중년여성에서폐경과급성심근경색증환자의임상경과를알아보고자하였다. 대상및방법 : 2005년 11월부터 2013년 12월까지한국인급성심근경색증등록사업에등록된 1,781명의 65세미만중년여성을대상으로폐경전그룹 (I군, 55세, 669 명 ) 과폐경후그룹 (II군, 세, 1,112명 ) 으로나누어서 1년후주요심혈관사건을비교분석하였다. 결과 : 폐경전여성은 669명 (I군 49.1 ± 5.6세 ) 이며폐경후여성은 1,112명 (II군 60.6 ± 2.6세 ) 이었다. 체질량지수 (I군 24.2 ± 3.2 kg/m 2 vs. II군 24.6±3.3kg/m 2 ; p = 0.048) 와복부둘레 (I군 90.3 ± 9.4 cm vs. II군 92 ± 9.5 cm; p = 0.005) 는 II군에서유의하게높았다. 고혈압 (I군 42.2% vs. II군 59.4%; p < 0.001), 당뇨병 (I군 27.4% vs. II군 35.7%; p < 0.001), 이상지질혈증 (I군 12.9% vs. II군 17.7%; p = 0.008) 은 II군에서유의하게더높았다. 흡연 (I군 2.7% vs. II군 1.9%; p < 0.001) 과가족력 (I군 12% vs. II군 6.8%; p < 0.001) 은 I군에서높게나타났다. 총콜레스테롤 (I군 ± 48.1 mg/dl vs. II군 ± 47.6 mg/dl; p < 0.001) 과저밀도지단백콜레스테롤 (I군 ± 40.8 mg/dl vs. II군 ± 47.9 mg/dl; p < 0.001) 은 II군에서유의하게높았다. 주요심혈관사건에있어서 1개월 (I군 1.7% vs. II군 2.5%; p = 0.481), 6개월 (I군 4.9% vs. II군 4.6%; p = 0.911), 12개월 (I군 7.6% vs. II군 8.5%; p = 0.551) 발생률 REFERENCES 1.
