摘要: 总结了31例经皮冠状动脉腔内血管成形术(PTCA)前后作核素运动心肌灌注断层显像的病例,其中男性25例,女性6例.PTCA前冠状动脉平均狭窄82.58%±16.04%,术后为17.7%±6.21%.运动心肌灌注断层显像显示PTCA术后心肌缺血完全消失及明显改善26例(83.9%).90.3%的病例PTCA术后运动试验较术前进步.认为运动心肌灌注断层显像可作为判断PTCA疗效的有效方法.

Abstract: We performed stress and rest myocardial perfusion tomography imaging in 31 patients before and after percutaneous transluminal coronary angioplasty(PTCA). The median time intervals before and after PTCA were 7.5 and 47.5 days respectively. There were 25 males and 6 females. Mean lesion grade pre-PTCA was 82.58%±16.04 % and mean residual lesion grade post-PTCA was 17.7%±6.21%. No major complications were encountered. Myocardial perfusion tomography imaging showed 26 cases with myocardial ischemia reverted to normal or approximately normal after PTCA. In 90.3% of the patients exercise stress was more improved than before PTCA.We conclude that exercise stress myocardial tomography imaging is a noninvasive and reliable method for the assesssment of PTCA therapeutic effect.

Key words: myocardial nuclide perfusion, PTCA, coronary heart disease
