1、冠心病右冠病變的臨床分析【摘要】日的：分析我科冠心病患者臨床癥狀和冠脈造影資料，總結(jié)右冠狹窄的臨床特點。方法：統(tǒng)計我科2002至2006所冇行冠脈造影并確診冠心病的冠脈狹窄資料，將其分為單支血管病變組和多支病變組，予右冠和左冠病變作對比分析，并予x2檢驗，以了解右冠病變的特點。結(jié)果：多支病變組右冠狹窄發(fā)病率和左冠相差不明顯(P>005),而單支病變組右冠狹窄發(fā)病率明顯低于左冠(P<0()01)o結(jié)論：右冠狹窄病變除發(fā)病率低外,這可能由于右冠和左冠及其它們供應(yīng)的心肌部位Z問存在一定解剖和生理的差異，使右冠狹窄時不易出心肌缺血，或心肌缺血癥狀
