[Abstract] Objective To explore effects of depression on quali
ty of life and exercise toler
ance in patients with coronary heart disease (CHD).
Methods 131 patients with C
HD completed Beck Depression Inventory (BDI) and the MOS 36_ Item Short_From Hea
lth survey(SF_36)independently. According to the scores of BDI, the patients
were divided into depression group (n=34) and non_depression group (n=97). Both
groups were given cardiopulmonary exercise testing (CPET).
Results (1) Compared with Chinese norms, the scores on all subsc
ales of SF_ 36 in 131 patients with CHD were lower, and there were sign
ificant differences on all subscales of SF_36 except that related to social func
tion (P<0.01). Furthermore, the scores on all subscales of SF_36 in depr
ession
group were lower than non_depression group, there were significant differences
on all subscales of SF_36 except those related to physical function and physi
cal role (P<0.05, or P<0.01). (2) The peak oxygen consumption (VO
2peak:), thres
hold of oxygen consumption of anaerobic metabolism (VO2AT), threshold anaerobi
c metabolism load (LoadAT) in depression group were lower than those in no
n_depression. VO2peak:(17.3±1.7)ml·kg-1·min-1 vs. (18.6
±2.9)ml·kg-1·min-1, P<0.05; VO2AT:(12.0±1.7)ml·kg
-1·min-1 vs.(13.2±2.2)ml·kg-1·min-1,P<0.01;
LoadAT:(30.7±11.4)J·s-1 vs.(36.0±13.9)J·s-1,P<0
.05.(3)
In patients with CHD, the scores of SF_36 and exercise tolerance were significan
tly correlated (P<0.05); the scores on all subscales of SF_36 measured by B
DI were significantly negatively correlated (P<
0.05); the
scores measured by BDI and VO2peak, VO2AT, LoadAT during CPET were sig
nificantly negatively correlated (P<0.05).
Conclusions Quality of life and exercise toler
ance of patients with CHD complicating depression decreased severely, and qualit
y of life and exercise tolerance closely related to depression.

冠心病是常見(jiàn)的心血管系統(tǒng)疾病,隨著人們生活水平的提高和生活方式的改變,其發(fā)病率和
病死率呈迅速上升趨勢(shì),現(xiàn)已成為中國(guó)居民死因增速最快的疾病[9]?冠心病具有
遷延不愈?反復(fù)發(fā)作的特征,而抑郁作為冠心病獨(dú)立的危險(xiǎn)因素,不僅與冠心病的發(fā)生?發(fā)
展有著密切的聯(lián)系,還會(huì)影響冠心病的預(yù)后,降低患者的生存時(shí)間和生存質(zhì)量[10]

者中
輕度抑郁占22.3%,明顯抑郁占10.4%,6.3%的患者服用抗抑郁藥?與抑郁積分的相關(guān)預(yù)
測(cè)因素為低VO2peak?低年齡?女性?低最大舒張壓?心絞痛和服用抗抑郁藥?
VO2peak和VO2AT是運(yùn)動(dòng)耐力最常用的指標(biāo),VO2pea
k的下降與氧傳輸(心排量?血液攜氧能力)?肺通氣效率?組織攝氧能力?肌肉骨骼功能
有關(guān),VO2peak的減少說(shuō)明運(yùn)動(dòng)耐力下降?在臨床試驗(yàn)中,由于主?客觀因素,導(dǎo)致患
者不能或不愿執(zhí)行最大運(yùn)動(dòng)試驗(yàn)量,而VO2AT?VE/VCO2等指標(biāo)可以從亞極量運(yùn)動(dòng)試驗(yàn)
中得出,因此VO2peak結(jié)合VO2AT?VE/VCO2評(píng)價(jià)
運(yùn)動(dòng)耐力更為客觀?
本研究共納入131例冠心病患者?研究發(fā)現(xiàn),冠心病患者的生存質(zhì)量下降,而且抑郁組冠心
病患者生存質(zhì)量較非抑郁組患者進(jìn)一步下降,通過(guò)相關(guān)分析證實(shí)冠心病患者生存質(zhì)量與運(yùn)動(dòng)
耐力密切相關(guān)?在相關(guān)分析中我們同樣證實(shí),抑郁對(duì)冠心病患者的生存質(zhì)量有重要影響,本
研究與國(guó)內(nèi)外相關(guān)研究的結(jié)論
一致?我們還發(fā)現(xiàn)抑郁組冠心病患者運(yùn)動(dòng)耐力低于非抑郁組患者,并且通過(guò)相關(guān)分
析證實(shí)抑郁與冠心病患者運(yùn)動(dòng)耐力密切相關(guān)?本研究中,冠心病患者中抑郁的發(fā)
病率為26%,明顯高于正常人群中抑郁的發(fā)病率,本研究結(jié)果也與國(guó)內(nèi)外其他類(lèi)似研究結(jié)果
相一致?
歐美發(fā)達(dá)國(guó)家在20世紀(jì)80?90年代已經(jīng)率先開(kāi)展以運(yùn)動(dòng)療法為核心的心臟康復(fù),心臟康復(fù)能
夠明顯改善患者運(yùn)動(dòng)耐力?降低心血管疾病死亡率?提高患者的生活質(zhì)量[13]?國(guó)
內(nèi)外學(xué)者
的很多研究也證實(shí),以運(yùn)動(dòng)訓(xùn)練?心理干預(yù)和教育督導(dǎo)等方式為主的心臟康復(fù)可從多種途徑
有效地改善冠心病患者的抑郁?焦慮情緒,從而使患者獲得最大的治療效益[14]?
以CPET為評(píng)估方法的心臟有氧運(yùn)動(dòng)康復(fù),在我國(guó)剛剛起步,運(yùn)動(dòng)康復(fù)對(duì)于冠心病患者的負(fù)性
情緒?生存質(zhì)量?運(yùn)動(dòng)耐力的改善,無(wú)疑為心臟病患者生活質(zhì)量的提高帶來(lái)福音?
