江立生邵琴卜軍何奔

目的對(duì)臨床上冠心病患者合并傳統(tǒng)心血管病危險(xiǎn)因素進(jìn)行分析。方法納入本中心2013年1月至2015年2月因冠心病或疑似冠心病行冠狀動(dòng)脈造影(CAG)檢查的住院患者，將存在嚴(yán)重冠心病并接受經(jīng)皮冠狀動(dòng)脈介入治療(PCI)的患者歸為PCI組(2808例)，不存在嚴(yán)重冠心病且未行PCI/冠狀動(dòng)脈旁路移植術(shù)(CABG)的患者歸為No-PCI/CABG組(3232例)。PCI組再分為急性ST段抬高心肌梗死(STEMI)組、非ST段抬高急性心肌梗死/不穩(wěn)定型心絞痛(NSTEMI/UA)組和穩(wěn)定型心絞痛(SA)組。對(duì)臨床上合并的傳統(tǒng)心血管病危險(xiǎn)因素進(jìn)行回顧性分析。結(jié)果(1)PCI組患者男性比例(75.4%比53.1%，P<0.0001)、平均年齡[(64.83±0.20)歲比(63.39±0.18)歲，P<0.0001]、高血壓病(66.7%比54.7%，P<0.0001)、糖尿病/糖耐量異常(37.0%比20.8%，P<0.0001)、卒中(7.0%比5.4%，P=0.0098)和慢性腎病(4.3%比2.8%，P=0.001)比例顯著高于No-PCI/CABG組；而兩組間高脂血癥的比例，差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05)。(2)PCI組中女性高血壓病(74.1%比64.3%,P<0.0001)、糖尿病/糖耐量異常(42.5%比35.3%，P=0.0007)和卒中(9.4%比6.2%，P=0.0054)比例均顯著高于男性，差異均有統(tǒng)計(jì)學(xué)意義；無(wú)論P(yáng)CI組還是No-PCI/CABG組，女性高脂血癥比例均顯著高于男性。(3)對(duì)PCI組進(jìn)行亞組分析發(fā)現(xiàn)，STEMI組男性比例顯著高于NSTEMI/UA組和SA組(83.9%比72.9%比72.3%，P<0.0001)，而發(fā)病年齡顯著小于NSTEMI/UA組和SA組[(62.54±0.45)歲比(65.15±0.28)歲比(66.17±0.34)歲，P<0.0001]。SA組高血壓病(71.9%比66.9%比60.0%，P<0.0001)和既往靶血管血運(yùn)重建(PCI/CABG)(33.9%比18.7%比7.2%，P<0.0001)比例顯著高于STEMI組和NSTEMI/UA組；NSTEMI/UA組糖尿病/糖耐量異常比例顯著高于STEMI組和SA組(39.7%比35.1%比34.4%，P<0.0001)，差異均有統(tǒng)計(jì)學(xué)意義；而高脂血癥、慢性腎病和卒中的比例三亞組間差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05)。結(jié)論高血壓病和糖尿病是冠心病最重要的危險(xiǎn)因素，既往靶血管血運(yùn)重建是SA和NSTEMI/UA患者靶血管再次血運(yùn)重建的重要原因；行PCI的嚴(yán)重冠心病患者中，男性比例高于女性，但女性合并高血壓病、糖尿病/糖耐量異常和卒中的比例高于男性。

冠心??；介入治療；危險(xiǎn)因素；回顧性分析

冠狀動(dòng)脈粥樣硬化性心臟病(冠心病)仍然是全球范圍內(nèi)首屈一指的公共衛(wèi)生問(wèn)題。近年來(lái)，歐美等發(fā)達(dá)國(guó)家冠心病死亡率呈逐年下降趨勢(shì)[1-2], 然而這種令人鼓舞的趨勢(shì)在中國(guó)卻并未出現(xiàn)，反而出現(xiàn)了更加嚴(yán)重的情況。根據(jù)《中國(guó)心血管病報(bào)告2014》數(shù)據(jù)，從2002年到2013年，中國(guó)冠心病和心肌梗死的死亡率仍逐年上升，2013年同2002年相比，中國(guó)農(nóng)村和城市冠心病的死亡率分別增加了3.6倍和2.5倍，急性心肌梗死的死亡率分別增加了4倍和4.3倍，而且預(yù)測(cè)未來(lái)10年中國(guó)冠心病的發(fā)病率和死亡率仍然上升[3]。

影響冠心病發(fā)病和死亡的因素有很多種，除與經(jīng)濟(jì)狀況、治療方式、生活習(xí)慣及種族等有關(guān)外，也與高血壓病、糖尿病、高脂血癥等傳統(tǒng)心血管病危險(xiǎn)因素密切相關(guān)[4-6]。近年來(lái)，有研究報(bào)道顯示，冠心病患者合并傳統(tǒng)心血管病危險(xiǎn)因素在部分東亞國(guó)家與歐美等西方國(guó)家相比存在一定差異[7-12]。在PLATO-ACS研究[7]中，亞裔患者并發(fā)糖尿病的比率高于非亞裔患者，而并發(fā)高脂血癥的比率則低于非亞裔患者。換言之，與歐美等發(fā)達(dá)國(guó)家相比，近年來(lái)中國(guó)逐年升高的冠心病死亡率也可能與中國(guó)人合并心血管病危險(xiǎn)因素情況及治療水平與歐美等發(fā)達(dá)國(guó)家不同有關(guān)。

本研究針對(duì)本中心經(jīng)冠狀動(dòng)脈造影(coronary angiography，CAG)證實(shí)存在嚴(yán)重阻塞性冠狀動(dòng)脈病變并接受經(jīng)皮冠狀動(dòng)脈介入治療(percutaneous coronary intervention，PCI)的冠心病患者和CAG檢查結(jié)果正常或僅提示輕度病變的住院患者合并傳統(tǒng)心血管病危險(xiǎn)因素的狀況進(jìn)行回顧性分析，以明確不同嚴(yán)重程度的冠心病合并傳統(tǒng)心血管病危險(xiǎn)因素的狀況，為科學(xué)管理冠心病危險(xiǎn)因素和降低冠心病發(fā)病率、死亡率提供依據(jù)。

2.1PCI組和No-PCI/CABG組人口學(xué)資料和心血管病危險(xiǎn)因素分析(表1)

PCI組患者男性比例[75.4%(2116/2808)比53.1%(1716/3232),P<0.0001]、平均年齡[(64.83±0.20)歲 比(63.39±0.18)歲，P<0.0001]均顯著高于No-PCI/CABG組，差異均有統(tǒng)計(jì)學(xué)意義。無(wú)論P(yáng)CI組還是No-PCI/CABG組，女性平均年齡均高于男性，分別為PCI組[(68.6±0.37)歲比(63.6±0.23)歲，P<0.0001]和No-PCI/CABG組[(64.5±0.26)歲比(62.4±0.26)歲,P=0.0144]，差異均有統(tǒng)計(jì)學(xué)意義。

2.2PCI組中各亞組人口學(xué)資料和心血管病危險(xiǎn)因素分析(表2)

亞組分析發(fā)現(xiàn)，STEMI組患者男性比例顯著高于NSTEMI/UA組和SA組(83.9%比72.9%比72.3%,P<0.0001)，而發(fā)病年齡則顯著低于后兩組[(62.54±0.45)歲比(65.15±0.28)歲比(66.17±0.34)歲，P<0.0001)]，差異均有統(tǒng)計(jì)學(xué)意義；但NSTEMI/UA組和SA組兩組間性別和發(fā)病年齡比較，差異均無(wú)統(tǒng)計(jì)學(xué)意義(均P>0.05)。在合并傳統(tǒng)心血管病危險(xiǎn)因素方面，SA組高血壓病(71.9%比66.9%比60.0%，P<0.0001)和既往靶血管血運(yùn)重建(PCI/CABG)(33.9%比18.7%比7.2%，P<0.0001)比例顯著高于NSTEMI/UA組和STEMI組，NSTEMI/UA組也顯著高于STEMI組(18.7%比7.2%，P<0.0001)，差異均有統(tǒng)計(jì)學(xué)意義。NSTEMI/UA組糖尿病/糖耐量異常比例顯著高于STEMI組和SA組(39.7%比35.1%比34.4%，P<0.0001)，而STEMI組和SA組差異無(wú)統(tǒng)計(jì)學(xué)意義(35.1%比34.4%，P>0.05)。三亞組間合并高脂血癥、慢性腎病和卒中的比例比較，差異均無(wú)統(tǒng)計(jì)學(xué)意義(均P>0.05)。STEMI患者平均住院時(shí)間[(11.14±0.22)d比(7.68±0.14)d比(6.65±0.14)d，P<0.0001]、住院費(fèi)用[(60 812±980)元比(53 743±615)元比(50 461±788)元，P<0.0001]和住院期間死亡率(3.1%比0.2%比0，P<0.0001)均顯著高于NSTEMI/UA組和SA組；NSTEMI/UA組平均住院時(shí)間[(7.68±0.14)d比(6.65±0.14)d，P<0.0001]、住院費(fèi)用[(53 743±615)元比(50 461±788)元，P<0.001]也均顯著高于SA組，差異均有統(tǒng)計(jì)學(xué)意義；但NSTEMI/UA組與SA組住院期間死亡率則差異無(wú)統(tǒng)計(jì)學(xué)意義。

3　討論

本中心的臨床結(jié)果分析顯示，PCI組患者合并高血壓病、糖尿病/糖耐量異常、卒中和慢性腎病的比例顯著高于No-PCI/CABG組患者，這與國(guó)外研究結(jié)果相一致[7-9]。此外，本研究結(jié)果還顯示，PCI組患者合并糖尿病/糖耐量異常的比例高于歐美等西方國(guó)家，而合并高脂血癥的比例卻顯著低于歐美等西方國(guó)家，與No-PCI/CABG組患者相當(dāng)[7-9]。日本及中國(guó)臺(tái)灣等東亞國(guó)家和地區(qū)的研究結(jié)果與本研究也基本相一致[14-15]，進(jìn)一步表明東亞國(guó)家和地區(qū)的冠心病患者在合并傳統(tǒng)心血管病危險(xiǎn)因素方面與歐美國(guó)家存在一定差別。

對(duì)PCI組患者進(jìn)行亞組分析發(fā)現(xiàn)，STEMI患者發(fā)病年齡低于NSTEMI/UA組和SA組患者，而住院時(shí)間、住院費(fèi)用和住院期間死亡率均顯著高于NSTEMI/UA組和SA組患者。本研究中住院期間死亡率與歐美發(fā)達(dá)國(guó)家相近甚至更低[16-17]。此外，本研究數(shù)據(jù)還顯示，接受PCI的SA患者合并高血壓病和既往靶血管血運(yùn)重建(PCI/CABG)史的比例最高，而NSTEMI/UA患者合并糖尿病/糖耐量異常比例最高。然而，STEMI組、NSTEMI/UA組和SA組三亞組間在合并高脂血癥、慢性腎病和卒中方面卻差異無(wú)統(tǒng)計(jì)學(xué)意義。國(guó)外PL-ACS研究[18]和GRACE研究[9]也顯示，NSTEMI/UA患者合并高血壓病、糖尿病和既往靶血管血運(yùn)重建的比例高于STEMI患者，這與本研究結(jié)果相一致。

近年來(lái)有較多研究顯示，男、女性冠心病患者在合并傳統(tǒng)心血管病危險(xiǎn)因素和預(yù)后方面存在一定差異，女性患者合并高血壓病、糖尿病、慢性腎病及高脂血癥的比例高于男性[19-22]，這可能是女性患者在預(yù)后方面比男性差的重要原因[23]。本研究結(jié)果也顯示，接受PCI/CABG的冠心病患者中，女性合并高血壓病、糖尿病/糖耐量異常和卒中的比例均高于男性，而未接受PCI/CABG的患者男、女間則差異無(wú)統(tǒng)計(jì)學(xué)意義，這與國(guó)外報(bào)道基本一致[24-25]。然而，兩組患者中，女性合并高脂血癥的比例均高于男性。

總之，高血壓病和糖尿病是冠心病最重要的危險(xiǎn)因素；由于PCI/CABG在冠心病治療中的廣泛應(yīng)用，既往靶血管血運(yùn)重建也成為SA和NSTEMI/UA患者靶血管再次血運(yùn)重建的重要原因。需要接受PCI的嚴(yán)重冠心病患者在卒中發(fā)生率和傳統(tǒng)心血管病危險(xiǎn)因素方面存在性別差異，男性發(fā)生需要行PCI的嚴(yán)重冠心病比例高于女性，而女性合并高血壓病、糖尿病/糖耐量異常和卒中的比例則高于男性。

ObjectiveTo analyze the real world status of traditional known cardiovascular risk factors in patients with coronary heart disease (CHD). Methods6040 in-hospital patients with CHD or suspected CHD undergoing angiography from 01/01/2013 to 02/28/2015 were retrospectively analyzed. According to angiography result, patients with severe coronary artery lesion and undergoing percutaneous coronary intervention (PCI) were enrolled in the PCI group(n=2808) and patients without severe coronary artery lesion and not undergoing PCI or CABG were enrolled in the No-PCI/CABG group (n=3232). Patients in the PCI group were further divided into 3 subgroups which were STEMI group, NSTEMI/UA group and stable angina (SA) group. Results(1) Compared with the No-PCI/CABG group, patients in the PCI group have higher ratio of male patients (75.4%vs. 53.1%,P<0.0001), older average age (64.83±0.20vs. 63.39±0.18 years old,P<0.0001), and higher existing rates of traditional risk factors including hypertension (66.7%vs. 54.7%,P<0.0001), diabetes/impaired glucose tolerance (IGT)(37.0%vs. 20.8%,P<0.0001), stroke(7.0%vs. 5.4%，P=0.0098)and chronic kidney disease (CKD) (4.3%vs. 2.8%,P=0.001), but there was no statistic difference in existing rates of dyslipidemia between the two groups. (2)In the PCI group，female patients had higher prevalence of hypertension (74.1%vs. 64.3%，P<0.001), diabetes/IGT (42.5%vs. 35.3%,P=0.0007) and stroke (9.4%vs. 6.2%,P=0.0054) than the male patients. There were no significant sex difference in these comorbidities as above in No-PCI/CABG group. Female patients had higher prevalence of dyslipidemia than male patients in both PCI and No-PCI/CABG groups. (3) Among all the 3 PCI subgroups, STEMI patients presented with youngest average age(62.54±0.45vs. 65.15±0.28vs. 66.17±0.34 years old,P<0.0001) and highest male patient ratio (83.9%vs. 72.9%vs. 72.3%,P<0.0001). Patients in the SA subgroup had the highest prevalence of hypertension and prior revascularization including PCI and CABG. Patients in the NSTEMI/UA subgroup had the highest rates of diabetes/IGT. No significant differences were observed in the prevalence of dyslipidemia, CKD and stroke among all the subgroups.ConclusionsHypertension and diabetes are the leading risk factors of coronary artery disease, and prior revascularization is also an important cause of stable angina and NSTEMI/UA undergoing PCI. Patients requiring PCI were found to be more of male gendor, but female patients has higher prevalence of traditional cardiovascular risk factors including hypertension, diabetes/IGT or stroke than male patients.
