摘　　要：目的　观察经皮冠脉腔内成形术 (PTCA )能否逆转冠心病 (CHD)患者的左室重构 (L VRM) .方法　以二维超声心动图 (2 DE)测量 1 5例成功实施 PTCA的左室收缩功能围术期演变 .结果　 L VRM的 CHD患者 (n=7)术后左室收缩末容积 (L VESV)首先缩小 (P<0 .0 5 ) ,随后 L VESV及左室舒张末容积 (L VEDV)均缩小显著 (P<0 .0 1 ) ;而无 L VRM者(n=8) ,术后 L VESV及 L VEDV均无变化 .结论　成功的选择性 PTCA围术期中 ,CHD患者的 L VRM可获得明显减轻 .AIM To evaluate effects of percutaneous transluminal coronary angioplasty (PTCA) on left ventricular function and volumes in the patients with left ventricular remodeling (LVRM). METHODS Fifteen patients with chronic anterior myocardial infarction were divided into two groups, LVRM and non LVRM group. The two dimensional echo cardiography (2DE) examination were done before PTCA and at 1～3 d, 7～10 d and 20～40 d after PTCA. Left ventricular end diastolic and end systolic volumes (LVEDV and LVESV) were measured using the modified Simpson's methods and recorded with videography. RESULTS In LVRM group ( n =7) LVESV begun to decline at 1～3 d after PTCA ( P <0.05), LVEDV and LVESV decreased significantly at 7～10 d after PTCA (both P <0.01). In non LVRM group ( n =8), no change was found in LVEDV and LVESV (both P >0.05). CONCLUSION Successful elective PTCA may reverse LVRM.
