背景 倦怠是一種壓力作用下的負(fù)性情感反應(yīng),目前關(guān)于倦怠與冠心病預(yù)后的研究較少。目的 觀察倦怠對(duì)急性冠脈綜合征(ACS)患者康復(fù)過(guò)程中體力恢復(fù)的影響,探索倦怠與ACS患者康復(fù)之間的關(guān)系,為改善患者預(yù)后提供理論依據(jù)。方法 本研究是一項(xiàng)前瞻性隊(duì)列研究。選擇2012年3月—2014年3月因首次發(fā)生ACS而收住昆明醫(yī)科大學(xué)第一附屬醫(yī)院心內(nèi)科的患者,病情穩(wěn)定后用哥本哈根倦怠量表的一般倦怠子量表評(píng)估其倦怠水平,按倦怠水平分為高倦怠組和低倦怠組。出院后1個(gè)月時(shí)隨訪,用簡(jiǎn)短體力測(cè)試方案(SPPB)檢測(cè)患者體力狀況,并再次評(píng)估倦怠水平,按倦怠水平變化情況分為4個(gè)亞組:持續(xù)高倦怠亞組、倦怠降低亞組、持續(xù)低倦怠亞組、倦怠升高亞組,比較各亞組之間體力狀態(tài)的差異,并構(gòu)建多重線性回歸模型進(jìn)一步檢驗(yàn)倦怠對(duì)體力恢復(fù)的影響。結(jié)果 低倦怠組患者SPPB體力評(píng)分較高倦怠組患者高,差異有統(tǒng)計(jì)學(xué)意義(t=-3.307,P<0.01)。持續(xù)低倦怠亞組、持續(xù)高倦怠亞組、倦怠降低亞組、倦怠升高亞組,對(duì)應(yīng)的SPPB評(píng)分分別為(9.7±1.6)、(7.8±1.8)、(8.6±1.8)、(7.3±2.0)分,各亞組患者出院后1個(gè)月時(shí)的SPPB評(píng)分間差異有統(tǒng)計(jì)學(xué)意義(F=8.933,P<0.001)。兩兩比較顯示,持續(xù)低倦怠亞組SPPB評(píng)分高于其他亞組,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。以SPPB體力評(píng)分為因變量構(gòu)建多重線性回歸模型,結(jié)果顯示,在排除年齡、性別等混雜因素后,出院時(shí)的一般倦怠子量表評(píng)分每升高1分,1個(gè)月后SPPB評(píng)分下降0.052分;出院后1個(gè)月時(shí)一般倦怠子量表評(píng)分每較基線增加1分,SPPB評(píng)分下降0.054分。結(jié)論 倦怠可導(dǎo)致ACS患者康復(fù)過(guò)程中的體力活動(dòng)下降,是ACS患者體力康復(fù)不良的獨(dú)立危險(xiǎn)因素。

冠心病是一種由多因素共同作用導(dǎo)致的慢性非傳染性疾病,除傳統(tǒng)的危險(xiǎn)因素如高血壓、糖尿病、吸煙、肥胖、血脂異常外,有越來(lái)越多的流行病學(xué)證據(jù)顯示,冠心病是一種典型的心身疾病[1],心理壓力在冠心病的發(fā)生、發(fā)展過(guò)程中發(fā)揮重要作用[2]。
人們?cè)诿鎸?duì)不同的壓力源時(shí),可能會(huì)產(chǎn)生某些負(fù)性情感反應(yīng),如焦慮、抑郁、倦怠等。焦慮和抑郁是最常見(jiàn)的負(fù)性情感反應(yīng),已有研究證實(shí),其在冠心病的發(fā)生、發(fā)展過(guò)程中發(fā)揮重要作用[3-4],能增加心肌梗死后患者心血管不良事件的發(fā)生率和再住院率[5-6],并與其病死率增加有密切關(guān)聯(lián)[7],是患者發(fā)生主要心血管不良事件的預(yù)測(cè)因素[8]。倦怠也是在壓力下產(chǎn)生的負(fù)性情感反應(yīng)之一,包括情感耗竭、身體疲勞和認(rèn)知疲憊3方面內(nèi)容[9],是一種與焦慮和抑郁不同的情感反應(yīng)[10]。目前對(duì)于倦怠與冠心病的相關(guān)研究尚不多見(jiàn),有研究顯示,倦怠水平上升會(huì)增加冠心病的發(fā)生風(fēng)險(xiǎn)[11-13],情感耗竭者在未來(lái)更容易發(fā)生心肌梗死[14-16],提示倦怠可能是未來(lái)發(fā)生冠心病的危險(xiǎn)因素。倦怠是否對(duì)急性心血管事件后的康復(fù)有不利影響尚不明確,本研究的目的是觀察倦怠對(duì)急性冠脈綜合征(ACS)患者康復(fù)過(guò)程中體力恢復(fù)的影響,探索倦怠與ACS患者康復(fù)之間的關(guān)系,為全面治療、改善患者預(yù)后提供理論依據(jù)。
1.1 病例納入標(biāo)準(zhǔn) (1)首次發(fā)作的ACS患者,包括不穩(wěn)定型心絞痛(UA)、非ST段抬高型心肌梗死(NSTEMI)、ST段抬高型心肌梗死(STEMI)。(2)精神狀況正常。(3)本人能夠閱讀和理解測(cè)試問(wèn)卷,或有旁人可以幫助患者閱讀和理解測(cè)試問(wèn)卷。
1.2 病例排除標(biāo)準(zhǔn) (1)既往有冠心病病史者,包括既往有心絞痛或心肌梗死病史、既往有經(jīng)皮冠狀動(dòng)脈介入治療(PCI)史或行冠狀動(dòng)脈旁路移植手術(shù)史。(2)有其他嚴(yán)重心血管疾病者,包括主動(dòng)脈夾層、急性肺栓塞、急性心包炎、心肌炎、心肌病、心內(nèi)膜炎。(3)有其他系統(tǒng)嚴(yán)重疾病者,包括急慢性感染、惡性腫瘤、甲狀腺疾病、肝腎功能明顯異常、嚴(yán)重電解質(zhì)紊亂、低血壓休克、近期發(fā)生嚴(yán)重創(chuàng)傷、風(fēng)濕或類風(fēng)濕等自身免疫性疾病。(4)妊娠或哺乳期婦女。(5)不能自行完成或在旁人解讀下仍不能完成相關(guān)問(wèn)卷調(diào)查者。
1.3 臨床資料 選擇2012年3月—2014年3月因首次發(fā)生ACS而收住昆明醫(yī)科大學(xué)第一附屬醫(yī)院心內(nèi)科的患者,均符合上述納入標(biāo)準(zhǔn),均已簽署知情同意書(shū)。
1.4 研究方法 本研究是一項(xiàng)前瞻性隊(duì)列研究。ACS患者經(jīng)治療病情穩(wěn)定后,用專業(yè)倦怠量表評(píng)估其倦怠水平,按倦怠水平分為高倦怠組和低倦怠組,出院后1個(gè)月進(jìn)行隨訪,檢測(cè)患者體力狀況,比較兩組患者體力狀態(tài)的差異。
1.4.1 資料收集 收集患者的一般資料和臨床資料。一般資料包括年齡、性別、文化程度、家庭常住人口、家庭平均月盈余、工作狀況等。臨床資料包括發(fā)病時(shí)間、既往史(高血壓、糖尿病、腦卒中、血脂異常史等)、心血管病家族史、個(gè)人史(吸煙史、飲酒史等)、入院時(shí)的體征及實(shí)驗(yàn)室指標(biāo)檢查、ACS類型(UA、NSTEMI或STEMI)、用藥和PCI情況。
1.4.2 問(wèn)卷調(diào)查 采用哥本哈根倦怠量表(CBI)一般倦怠子量表評(píng)估患者的一般倦怠水平,患者出院前和出院后1個(gè)月分別接受兩次倦怠評(píng)估。CBI是由Kristensen于2005年開(kāi)發(fā)的評(píng)估倦怠水平的測(cè)量工具,該量表答案選項(xiàng)采用Likert 5級(jí)結(jié)構(gòu),評(píng)分范圍0~100分,分?jǐn)?shù)越高表明倦怠程度越高[17]。CBI中文版已在中國(guó)人群中驗(yàn)證過(guò)信度和效度,證實(shí)可應(yīng)用于中國(guó)人群[18]。
1.4.3 分組方案 受試者的分組方案見(jiàn)圖1。由于目前國(guó)內(nèi)外尚無(wú)評(píng)判倦怠的標(biāo)準(zhǔn)界值,故本研究以一般倦怠子量表評(píng)分的上四分位數(shù)(P75)為界;患者出院前進(jìn)行第1次評(píng)估,一般倦怠子量表評(píng)分≥P75為高倦怠組,一般倦怠子量表評(píng)分 注:ACS=急性冠脈綜合征,CBI=哥本哈根倦怠量表 圖1 分組方案 Figure 1 Scheme of grouping 1.4.4 體力測(cè)試 患者出院后1個(gè)月,采用簡(jiǎn)短體力測(cè)試方案(Short Physical Performance Battery,SPPB)測(cè)試其體力狀況。SPPB是美國(guó)國(guó)家老年病研究所開(kāi)發(fā)的一個(gè)用簡(jiǎn)單動(dòng)作測(cè)量患者下肢體力狀況的客觀測(cè)試方案,主要針對(duì)的是老年人、心肺功能不良或體力狀況不好者,測(cè)試包括平衡測(cè)試、步速測(cè)試和座椅站立測(cè)試3部分,測(cè)試方案詳見(jiàn)圖2。SPPB評(píng)分范圍0~12分,分?jǐn)?shù)越高表明患者的體力狀況越好。有研究發(fā)現(xiàn), SPPB評(píng)分降低與心血管病患者死亡率增高、身體機(jī)能減退等不良預(yù)后結(jié)局相關(guān),提示SPPB評(píng)分可以作為一種評(píng)價(jià)心血管疾病預(yù)后趨勢(shì)的預(yù)測(cè)因子[19]。 2.1 分組 本研究共納入94例ACS患者,退出3例,實(shí)際完成隨訪91例?;颊叱鲈簳r(shí)一般倦怠子量表評(píng)分的P75=58.3分,以此為界,將患者分為高倦怠組和低倦怠組,分別是26、65例。出院后1個(gè)月時(shí)再進(jìn)行倦怠評(píng)估,根據(jù)倦怠變化情況,得到4個(gè)亞組,分別為:持續(xù)高倦怠亞組17例、持續(xù)低倦怠亞組58例、倦怠升高亞組7例、倦怠降低亞組9例。 圖2 SPPB體能測(cè)試方案 2.2 患者的基線資料 2.2.1 一般資料 高倦怠組患者的年齡低于低倦怠組患者,差異有統(tǒng)計(jì)學(xué)意義(P=0.025),其余各指標(biāo)比較,差異均無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05,見(jiàn)表1)。 2.2.2 臨床資料 高倦怠組患者既往飲酒率低于低倦怠組患者,差異有統(tǒng)計(jì)學(xué)意義(P=0.038);其余各指標(biāo)間比較,差異均無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05,見(jiàn)表2)。 2.3 高倦怠組和低倦怠組患者體力恢復(fù)情況比較 高倦怠組患者出院后1個(gè)月SPPB評(píng)分為(8.1±1.8)分,低倦怠組為(9.5±1.8)分,兩組間差異有統(tǒng)計(jì)學(xué)意義(t=-3.307,P<0.01)。 表1 高倦怠組和低倦怠組患者一般資料比較 注:a為χ2值 表2 兩組患者臨床資料比較 注:a為t值,-為未行統(tǒng)計(jì)學(xué)比較;ACS=急性冠脈綜合征,UA=不穩(wěn)定型心絞痛,NSTEMI=非ST段抬高型心肌梗死,STEMI=ST段抬高型心肌梗死,LDL-C=低密度脂蛋白膽固醇,HDL-C=高密度脂蛋白膽固醇,ACEI/ARB= 血管緊張素轉(zhuǎn)換酶抑制劑/血管緊張素Ⅱ受體拮抗劑,PCI=經(jīng)皮冠狀動(dòng)脈介入治療 2.4 倦怠變化對(duì)患者體力恢復(fù)的影響 根據(jù)患者出院時(shí)和出院后1個(gè)月一般倦怠子量表評(píng)分結(jié)果,將患者分為4個(gè)亞組:持續(xù)低倦怠亞組、持續(xù)高倦怠亞組、倦怠降低亞組、倦怠升高亞組,對(duì)應(yīng)的SPPB評(píng)分分別為:(9.7±1.6)、(7.8±1.8)、(8.6±1.8)、(7.3±2.0)分。各亞組患者出院后1個(gè)月SPPB評(píng)分間差異有統(tǒng)計(jì)學(xué)意義(F=8.933,P<0.001)。進(jìn)一步兩兩比較結(jié)果顯示,持續(xù)低倦怠亞組SPPB評(píng)分均高于其他亞組,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。 2.5 多重線性回歸分析 以SPPB評(píng)分為因變量,構(gòu)建兩個(gè)多重線性回歸模型,模型一:以出院時(shí)的一般倦怠子量表評(píng)分、年齡、性別、ACS類型、文化程度、工作狀況、家庭月平均盈余、體質(zhì)指數(shù)、高血壓病史、糖尿病病史、血脂異常病史、腦卒中病史、心血管病家族史、吸煙史和飲酒史為自變量,構(gòu)建多重線性回歸模型。連續(xù)變量直接代入方程,分類變量先轉(zhuǎn)換成啞變量再代入方程。結(jié)果顯示:一般倦怠子量表評(píng)分進(jìn)入回歸方程,在排除上述混雜因素的影響后,出院時(shí)的一般倦怠子量表評(píng)分每升高1分,1個(gè)月后的SPPB評(píng)分下降0.052分(見(jiàn)表3)。 模型二:以一般倦怠子量表評(píng)分的變化值(出院后1個(gè)月-出院時(shí))為自變量,其余自變量同模型一,構(gòu)建多重線性回歸模型。結(jié)果顯示,排除混雜因素的影響后,出院后1個(gè)月一般倦怠子量表評(píng)分每較基線增加1分,SPPB評(píng)分下降0.054分(見(jiàn)表4)。 表3 ACS患者SPPB評(píng)分影響因素的多重線性回歸模型一

運(yùn)動(dòng)能力降低影響心血管疾病患者預(yù)后 急性心肌梗死是全球范圍內(nèi)致死和致殘的主要疾病之一,患者在心臟事件后的體力恢復(fù)情況影響著遠(yuǎn)期的生活質(zhì)量。已有文獻(xiàn)報(bào)道,冠心病患者缺乏體力活動(dòng)會(huì)對(duì)心功能造成不利影響[20],不利于患者心臟事件后心功能的康復(fù),并且運(yùn)動(dòng)能力降低與冠心病復(fù)發(fā)有關(guān)[21]。運(yùn)動(dòng)水平是5年內(nèi)病死率的獨(dú)立預(yù)測(cè)指標(biāo)[22],活動(dòng)能力下降的患者遠(yuǎn)期發(fā)生心臟不良事件的風(fēng)險(xiǎn)升高[23]。另外,缺乏體力活動(dòng)會(huì)加重患者身體的失能狀態(tài),表現(xiàn)為日常生活能力下降,如穿衣、走路、購(gòu)物等日?;顒?dòng)受到限制,部分甚至全部需要依賴別人協(xié)助[24],使患者的生活質(zhì)量明顯下降。 3.2 倦怠可導(dǎo)致ACS患者的運(yùn)動(dòng)能力下降 本研究顯示,倦怠程度高的患者在出院后1個(gè)月SPPB評(píng)分低于低倦怠患者;出院后1個(gè)月內(nèi),倦怠持續(xù)處于高水平者,或倦怠水平由低轉(zhuǎn)高者,其SPPB評(píng)分較持續(xù)低倦怠組患者低,提示倦怠對(duì)ACS患者的體力恢復(fù)有不利影響,倦怠程度升高可導(dǎo)致患者體力恢復(fù)不良。進(jìn)一步行多重線性回歸分析顯示,在排除了年齡、性別、既往史、家族史等混雜因子的影響后,SPPB評(píng)分與出院時(shí)一般倦怠子量表評(píng)分呈負(fù)相關(guān),且SPPB與一般倦怠子量表評(píng)分的變化值也呈負(fù)相關(guān)關(guān)系,提示倦怠程度是使患者體力活動(dòng)下降的獨(dú)立危險(xiǎn)因素。 3.3 倦怠引起運(yùn)動(dòng)能力下降的可能機(jī)制探討 倦怠對(duì)ACS體力恢復(fù)產(chǎn)生負(fù)面影響的機(jī)制可能是放大了患者某些非特異性不適的嚴(yán)重程度和增加了患者內(nèi)心負(fù)性情感反應(yīng)程度,進(jìn)而對(duì)自我體力主觀評(píng)價(jià)下降[25]。有研究顯示,多數(shù)冠心病患者認(rèn)為體力差并減少體力活動(dòng)是因?yàn)榛顒?dòng)過(guò)程中出現(xiàn)了氣促、疲憊感、虛弱感等非特異性癥狀,真正出現(xiàn)胸部緊縮感或不適者較少[25],而負(fù)性情感反應(yīng)可能會(huì)加重患者對(duì)上述不適癥狀的感受。2011年荷蘭Eramus醫(yī)學(xué)中心對(duì)715例冠心病患者調(diào)查后發(fā)現(xiàn),這些患者術(shù)后1年合并焦慮癥狀者占75.6%,合并抑郁癥狀者占81.4%[26],國(guó)內(nèi)韓立憲等[27]研究也有相似結(jié)論。焦慮和抑郁等負(fù)性情感可以轉(zhuǎn)化為軀體癥狀,諸如胸痛等不適,導(dǎo)致患者生活質(zhì)量下降[28],阻礙患者的康復(fù)活動(dòng)[29]。倦怠作為一種與焦慮和抑郁不同的負(fù)性情感反應(yīng),也可能會(huì)轉(zhuǎn)化為上述軀體癥狀。Armon等[30]對(duì)1 704名健康的志愿者進(jìn)行了3年的隨訪觀察,發(fā)現(xiàn)倦怠可能是引起肌肉疼痛的一個(gè)危險(xiǎn)因素。對(duì)于ACS患者這一特殊人群,胸痛對(duì)他們來(lái)說(shuō)是一個(gè)危險(xiǎn)信號(hào),而對(duì)于這種感覺(jué)的認(rèn)知可能擴(kuò)大到整個(gè)身體。患者可能因?yàn)樯眢w任意部位,尤其是胸背部的疼痛不適而感到緊張害怕,進(jìn)而懼怕活動(dòng),導(dǎo)致體力受限。本研究結(jié)果說(shuō)明倦怠會(huì)造成ACS患者的自身活動(dòng)能力下降,提示倦怠是影響患者體力恢復(fù)的因素之一。 3.4 適當(dāng)?shù)捏w力活動(dòng)對(duì)ACS患者康復(fù)的重要性 適當(dāng)?shù)捏w力活動(dòng)可以降低心血管相關(guān)的病死率和總病死率[31],對(duì)ACS患者的康復(fù)起到重要作用。目前的指南推薦,冠心病病情穩(wěn)定的患者每日應(yīng)有至少30 min的鍛煉時(shí)間[32]。也有研究證實(shí),以運(yùn)動(dòng)康復(fù)為核心的心臟康復(fù)計(jì)劃,可使患者的病死率下降21%~34%,說(shuō)明運(yùn)動(dòng)康復(fù)可以降低患者急性心血管事件的發(fā)病率和住院率,降低患者發(fā)生猝死的風(fēng)險(xiǎn),其效果與心血管病預(yù)防用藥相當(dāng),但費(fèi)用明顯低于預(yù)防用藥[33]。然而,倦怠等負(fù)性情感反應(yīng)對(duì)患者體力活動(dòng)的負(fù)面影響將在很大程度上降低這些獲益,提醒醫(yī)生在指導(dǎo)患者科學(xué)的運(yùn)動(dòng)康復(fù)時(shí),不應(yīng)該僅局限于心血管病本身,還應(yīng)該重視患者的心理、情緒管理,注重“雙心健康”。 本文的局限性和創(chuàng)新點(diǎn): 本文的局限性:樣本例數(shù)偏小,研究周期較短,并且以量表方式進(jìn)行心理評(píng)價(jià),患者在完成的過(guò)程中不可避免地受到主觀因素影響,可能會(huì)對(duì)研究結(jié)果造成誤差。 本文的創(chuàng)新點(diǎn):(1)揭示了一般倦怠對(duì)ACS患者的體力恢復(fù)有影響,倦怠水平越高,體力下降程度越大;動(dòng)態(tài)觀察倦怠變化情況的結(jié)果也與上述結(jié)論一致。(2)采用SPPB測(cè)試患者體力狀況,與6分鐘步行試驗(yàn)等傳統(tǒng)方法相比,SPPB更簡(jiǎn)便、安全,且不受測(cè)試環(huán)境限制,可廣泛應(yīng)用于老年人或心肺功能不良患者的體力測(cè)試。

(本文編輯:趙躍翠) Influence of Burnout on the Physical Strength Recovery of Patients With Acute Coronary Syndrome ZHANGMin,SHIYun-ke,LIULing,etal. DepartmentofCardiology,theFirstAffiliatedHospitalofKunmingMedicalUniversity,Kunming650032,China Background Burnout is a kind of negative affective response under pressure,and there is a lack of researches about burnout and the prognosis of coronary heart disease at present.Objective To observe the influence of burnout on the physical strength recovery in the process of rehabilitation of patients with acute coronary syndrome(ACS) and examine the relationship between burnout and the rehabilitation of ACS patients,in order to provide theoretical references for the improvement of prognosis of ACS patients.Methods In this prospective cohort study,we enrolled patients having first ACS onset in the Department of Cardiology,the First Affiliated Hospital of Kunming Medical University from March 2012 to March 2014 as subjects,and evaluated the subjects′ burnout level by using the general burnout subscale of Copenhagen Burnout Inventory after their condition got stable.According to burnout level,the subjects were assigned into high burnout group and low burnout group.During the follow-up visits to the subjects one month after discharge,physical strength of the subjects was tested by using Short Physical Performance Battery (SPPB) and burnout level was evaluated again.According to the changes of burnout level,the subjects were divided into four subgroups:continuing high burnout subgroup,continuing low burnout subgroup,decreasing burnout subgroup and increasing burnout subgroup.Then physical strength status was compared among the four subgroups,and multiple linear regression model was built to further examine the influence of burnout on the recovery of physical strength.Results Low burnout group was significantly higher (t=-3.307,P<0.01) than high burnout group in SPPB score.The scores of continuing low burnout subgroup,continuing high burnout subgroup,decreasing burnout subgroup and increasing burnout subgroup were (9.7±1.6),(7.8±1.8),(8.6±1.8) and(7.3±2.0)respectively.The four subgroups were significantly different (F=8.933,P<0.001) in the SPPB score one month after discharge.The continuing low burnout subgroup was higher (P<0.05) than the other three subgroups in SPPB score.The multiple linear regression model with SPPB score as dependent variable showed the following results:after the exclusion of the confounding factors like age and gender,one score increase in the general burnout subscale finished at discharge was associated with 0.052 score decrease in the SPPB evaluation one month later;one score higher than baseline in the general burnout subscale finished one month after discharge was associated with 0.054 score decrease in the SPPB evaluation.Conclusion Burnout could lead to the decrease of physical strength in the process of rehabilitation of ACS patients and is an independent risk factor for the poor rehabilitation of ACS patients.
