摘要 目的探讨320排螺旋CT心肌灌注技术在冠心病心功能评价中的应用价值。方法选取2013年1月至2014年10月来第三军医大学新桥医院就诊的30例出现可逆性心肌缺血的冠心病患者作为研究对象,并选取同期进行体检的30例健康人作为对照组。采用320排螺旋CT心肌灌注扫描评价两组研究对象多巴酚丁胺负荷前后心功能指标的变化情况。结果负荷试验前后,两组研究对象的每搏输出量(SV)、收缩末期容积(ESV)、舒张末期容积(EDV)以及射血分数比较,差异均有统计学意义(P<0.05);负荷后,对照组的SV、ESV、EDV较负荷前显著降低[(58.0±5.2)mL比(62.2±5.2)mL;(48.8±3.8)cm^3比(51.8±4.6)cm^3;(51.8±4.6)mL比(112.5±7.3)mL](P<0.05),而射血分数无显著变化[(65.0±4.0)%比(64.9±3.8)%](P>0.05),而冠心病组患者的SV、ESV、EDV与负荷前比较差异无统计学意义(P>0.05)[(66.9±5.4)mL比(66.8±5.2)mL;(61.7±4.2)cm^3比(61.8±4.5)cm^3;(133.0±6.7)mL比(133.1±6.1)mL],而射血分数较之前显著降低[(53.5±5.4)%比(56.6±5.3)%](P<0.05)。结论 320排螺旋CT心肌灌注技术能够评价冠心病缺血心肌的心功能受损程度,为冠心病的临床诊治提供参考依据。 Objective To study and investigate the application of 320-slice spiral CT myocardial perfusion in evaluating cardiac function of coronary heart disease. Methods Total of 30 cases of coronary heart disease with reversible myocardial ischemia in Xinqiao Hospital from Jan. 2013 to Oct. 2014 were included as a coronary heart disease group,and 30 healthy persons for health examination during the same period were included as a control group. 320-slice spiral CT myocardial perfusion scan was used to evaluate the cardiac function before and after dobutamine stress test. Results Before and after dobutamine stress test,the stroke volume( SV),end-systolic volume( ESV),end-diastolic volume( EDV) and ejection fraction of the two groups had statistically significant difference( P〈0. 05). After dobutamine stress test,the SV,ESV,EDV of the control group were significantly lower than before [( 58. 0 ± 5. 2) mL vs( 62. 2 ± 5. 2) mL;( 48. 8 ±3. 8) cm^3vs( 51. 8 ± 4. 6) cm^3;( 51. 8 ± 4. 6) mL vs( 112. 5 ± 7. 3) mL]( P〉0. 05),whereas there was no significant change in ejection fraction [( 65. 0 ± 4. 0) % vs( 64. 9 ± 3. 8) % ]( P〈0. 05),the SV[( 66. 9 ±5. 4) mL vs( 66. 8 ±5. 2) mL],ESV[( 61. 7 ±4. 2) cm^3vs( 61. 8 ± 4. 5) cm^3],EDV[( 133. 0 ±6. 7) mL vs( 133. 1 ± 6. 1) mL] of coronary heart disease group had no significant difference( P〉0. 05),and ejection fraction [( 53. 5 ± 5. 4) % vs( 56. 6 ± 5. 3) %] was significantly lower than before( P〈0. 05). Conclusion 320-slice spiral CT myocardial perfusion technique can evaluate the damage level of cardiac function and provide reference for the clinical diagnosis and treatment of coronary heart disease.
