[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.

冠状动脉粥样硬化性心脏病(coronary heart disease,CHD),简称冠心病,是一种公
认的心身疾病,其发生?发展以及预后均和心理社会因素有着密切的联系[1~3]?
国外研究
发现,冠心病患者心血管系统功能易受精神因素的影响,抑郁?焦虑等负性情绪在冠心病患
者中普遍存在[4]?其中抑郁情绪自20年前开始就被认为是冠心病独立的危险因素
,近15年
来抑郁还被认为是导致冠心病死亡的危险因素[5]?本研究初步探究抑郁情绪对冠
心病患者生存质量?运动耐力的影响,为冠心病患者系统性康复提供依据?
1 资料与方法
1.1 一般资料:研究对象为2012年12月至2013年7月,在同济医院心内科接受治
疗并进行康复的131例冠心病患者,经心肌同位素检测?超声心动图,或冠状动脉造影确诊
为冠心病?心功能NYHA分级Ⅱ~Ⅲ级?患者无智力障碍,有认知能力,语言清晰,能较好地
进行语言沟通,并排除既往
有神经精神疾病史?严重认知功能障碍及检查不合作者?小学文化程度以下患者?131例患
者中男103人,女28人;年龄40~70(57.3±7.5)岁?患者一般资料构成情况见表1?
所有患者试验前均经介绍研究流程,签订知情同意书?本研究通过同济大学附属同济医院伦
理委员会审批,伦理委员会批件文号为LL(H)_08_13,并在中国临床试验中心注册?
1.2 方法:
1.2.1 调查方法:使用自制的调查表,由本研究第一作者对被调查者实施面访?调查内
容包括患者的基本情况:姓名?性别?出生年月?文化程度?职业?婚姻?诊断?病史及
BMI等?由患者本人在安静环境下独立填写完成贝克抑郁自评量表(BDI)[6]:BDI
对每个问题做出0到3的评分?总分为0~39分?总分
≤4分,无抑郁或极轻
微;5~13分,轻度抑郁;14~20分,中度抑郁;≥21分,重度抑郁?将131例患者中BDI评
分≥5分的34例定为抑郁组,<5分的97例定为无抑郁组?两组患者均独立填写完成由美国波
士顿健康研究所研制的简明健康测量量表(SF_36)[7]:包括36个条目,分为8个维度
,分别为生理功能(PF)?生理职能(RP)?躯体疼痛(BP)?总体健康(GH)?活力(VT)?社会功
能(SF)?情感职能(RE)和精神健康(MH)?生活质量各维度分值记分方法运用累加法
,按最后分值计算原始分数,再用标准公式计算转换分数为0~100的标准分?得分越高,
生存质量越好?
1.2.2 CPET:心肺运动试验(cardiopulmonary exercise test,CPET)包括心电图负荷
试验和运动时气体代谢分析?采用的仪器包括丹麦Innovision公司生产的气体再呼吸系统?
美国通用公司生产的运动测试系统负荷Ramp10方案,患者试验开始后的每一次呼出的气体均
被气体再呼吸系统连续监测?无氧代谢阈值氧耗量(VO2AT)用V_slope方法判定?所有受
试者均能耐受心肺运动试验,无1例出现明显的不良反应?
1.3 统计学处理:采用SPSS 21.0软件进行统计分析,计量资料均以(

冠心病是常见的心血管系统疾病,随着人们生活水平的提高和生活方式的改变,其发病率和
病死率呈迅速上升趋势,现已成为中国居民死因增速最快的疾病[9]?冠心病具有
迁延不愈?反复发作的特征,而抑郁作为冠心病独立的危险因素,不仅与冠心病的发生?发
展有着密切的联系,还会影响冠心病的预后,降低患者的生存时间和生存质量[10]
?
Belardinelli等[11]报道118例经皮冠状动脉介入(PCI)治疗的冠心病患者进
行为期6月的运动康复?术后血管再狭窄率没有受运动康复的影响,但训练组的患者峰值耗
氧量增加26%,生活质量参数提高27%?Swardfager等[12]报道366例冠心病康复患
者中
轻度抑郁占22.3%,明显抑郁占10.4%,6.3%的患者服用抗抑郁药?与抑郁积分的相关预
测因素为低VO2peak?低年龄?女性?低最大舒张压?心绞痛和服用抗抑郁药?
VO2peak和VO2AT是运动耐力最常用的指标,VO2pea
k的下降与氧传输(心排量?血液携氧能力)?肺通气效率?组织摄氧能力?肌肉骨骼功能
有关,VO2peak的减少说明运动耐力下降?在临床试验中,由于主?客观因素,导致患
者不能或不愿执行最大运动试验量,而VO2AT?VE/VCO2等指标可以从亚极量运动试验
中得出,因此VO2peak结合VO2AT?VE/VCO2评价
运动耐力更为客观?
本研究共纳入131例冠心病患者?研究发现,冠心病患者的生存质量下降,而且抑郁组冠心
病患者生存质量较非抑郁组患者进一步下降,通过相关分析证实冠心病患者生存质量与运动
耐力密切相关?在相关分析中我们同样证实,抑郁对冠心病患者的生存质量有重要影响,本
研究与国内外相关研究的结论
一致?我们还发现抑郁组冠心病患者运动耐力低于非抑郁组患者,并且通过相关分
析证实抑郁与冠心病患者运动耐力密切相关?本研究中,冠心病患者中抑郁的发
病率为26%,明显高于正常人群中抑郁的发病率,本研究结果也与国内外其他类似研究结果
相一致?
欧美发达国家在20世纪80?90年代已经率先开展以运动疗法为核心的心脏康复,心脏康复能
够明显改善患者运动耐力?降低心血管疾病死亡率?提高患者的生活质量[13]?国
内外学者
的很多研究也证实,以运动训练?心理干预和教育督导等方式为主的心脏康复可从多种途径
有效地改善冠心病患者的抑郁?焦虑情绪,从而使患者获得最大的治疗效益[14]?
以CPET为评估方法的心脏有氧运动康复,在我国刚刚起步,运动康复对于冠心病患者的负性
情绪?生存质量?运动耐力的改善,无疑为心脏病患者生活质量的提高带来福音?
