<STRONG>研究显示：抑郁症与心脏病之间存在密切关系</STRONG>

　　<STRONG>Depression, Heart Disease Often Go HandinHand</STRONG>
　　抑郁症是美国人在日常生活中最常遇到的健康问题之一，而心脏病则是造成该国死亡的“头号杀手”。近日，美国健康专家指出，尽管这两种疾病的确会单独出现在不同患者身上，但有关研究显示，在很多情况下，两种疾病还是存在着一定的关系。
　　<STRONG>抑郁症是患心脏病的前兆</STRONG>
　　据路透社3月1日报道，美国著名的Mayo诊所的健康期刊最近发表报告指出，抑郁症在心脏病患者中的发病率要高于那些没有心脏病的人。三分之一的心脏病患者曾经出现过抑郁症的相关症状，而在全体成年人中，这一比例仅为二十分之一。研究还发现，抑郁症其实也是预示某人患有心脏病的一个前兆。在一项对绝经后女性进行的研究中，调查人员发现，那些出现过抑郁症状的被调查者即使以前从未有过心脏病史，其日后患上心脏病或是因此病而死亡的概率，也会比没有出现过抑郁症状的同伴高出50％。
　　为了给这两种疾病间存在的联系做出解释，Mayo诊所的专家们指出，抑郁症并不仅仅会对一个人的精神状态产生负面影响，它同时还会损害这个人的肉体健康。抑郁症可以导致人体血压升高心率失常，还会使人体内应激激素的分泌水平呈现出长期居高不下的状态，而这会加大心脏的工作负担。
　　Mayo诊所女性心脏门诊部负责人沙罗妮·海耶斯博士说：“即使你以前从未得过心脏病，但如果你的情绪长期萎靡不振的话，那你日后患上心脏病的危险就会有所增加。需要进一步指出的是，对于那些有过抑郁症病史的人来说，一旦他们患上了心脏病，则会更容易出现反复发作的现象。”
　　<STRONG>医生也常常对此视而不见</STRONG>
　　海耶斯指出，这两种疾病间所存在的复杂关系可能会使其中至少一种病症无法得到及时确诊。此前进行的一项研究显示，即使是医生和护士也往往会忽略对那些心脏病患者进行抑郁症方面的检查，而让患者自己辨别出其身上存在的抑郁症状就更是难上加难了。海耶斯说：“这种现状说明有些心脏病患者需要接受与抑郁症有关的治疗，或者至少应对其在这方面做出进一步检查，但我们却极有可能对此持一种视而不见的态度。”
　　抑郁症的具体症状包括持续不退的悲伤情绪，对日常活动丧失兴趣，经常产生负罪感、无望感、疲劳感或紧张感，以及食欲改变等。一些与抑郁症有关的症状可能为很多心脏病患者所忽视，或者是被视做由于人体衰老或心脏出现问题后所产生的一种正常现象。海耶斯对于心脏病患者提出了如下建议：“在你刚刚被确诊患有心脏病时，感到伤心和悲哀可能是一种十分自然的反应，但如果这些情感经久不退或者是令你的正常身体机能受到了干扰的话，那么做为一个心脏病患者，你应当对此格外重视并前往医院检查自己是否已经同时患上了抑郁症。”
　　Depression is one of the most common health disorders in theUS,and heart disease is a leading cause of death. Although theycanand do occur setely, research shows that the two conditionsareoften connected, health experts write in the February issue oftheMayo Clinic Womens HealthSource.
　　Previous studies have shown that depression is more commonamongpeople with heart disease than among those without.Researchersfound that one in three heart attack survivorsexperiencedepression, compared to about one in 20 adults in thegeneralpopulation.
　　Depression has also been shown to be a precursor to heartdisease.In one study of postmenopausal women, investigators foundthat thosewith symptoms of depression were 50 percent more likelyto developor die from heart disease than those without suchsymptoms, eventhough they had no prior history of heartdisease.
　　Explaining the connection between the two conditions, theMayoClinic experts note that depression affects not only the mindbutalso physical health. Depression has been linked to increasedbloodpressure and abnormal heart rhythms, as well aschronicallyelevated stress hormone levels, which can increase theheartsworkload.
　　Even if you dont have heart disease, if you arechronicallydepressed, you are at somewhat increased risk of heartdisease,Dr. Sharonne Hayes, a specialty reviewer of theHealthSourcepublication, told Reuters Health. Whats more, peoplewith ahistory of depression are susceptible for recurrence iftheydevelop heart disease, said Hayes, who is also the director oftheWomens Heart Clinic at the Mayo Clinic inRochester,Minnesota.
　　Yet, the complex interplay between the two conditions mayallowfor one or both to go undiagnosed, according to theHealthSourcearticle.
　　Findings from a previously reported study show that evendoctorsand nurses do not always readily assess depression inheartpatients, and it is hard for patients to recognize theirowndepressive symptoms, Hayes said.
　　This tells us were probably missing some people who need tobetreated or at least further evaluated (for depression),shesaid.
　　Symptoms of depression include persistent sadness, lossofinterest in normal activities, feelings of guilt orhopelessness,tiredness, restlessness and changes in appetite. Someof thesesymptoms may be discounted by many with heart disease orviewed asa natural part of dealing with aging or heart-healthproblems, thereport indicates.
　　According to Hayes, It may be natural to grieve and be sad ifyouhave a new diagnosis of heart disease. If those feelingspersist orinterfere with normal daily ning, however, heartpatients shouldspecifically mention that and be evaluated (fordepression), sheadvised.（张咏）[双语新闻]布莱尔要帮英国女孩儿找工作[双语新闻]儿子数学作业难倒贝克汉姆[双语新闻]青少年肥胖与家庭周边环境有关[双语新闻]美国一家庭出现7位总统[双语新闻]发现：早期人类祖先曾是八字脚
