摘  要:目的 :探讨不同QRS波形态的慢性心力衰竭(心衰)患者对心脏再同步化治疗(CRT)的临床反应性。方法 :选取2010-03至2013-07在郑州大学第二附属医院及郑州市第七人民医院心内科接受CRT治疗的52例慢性心衰患者为研究对象。根据真性完全性左束支传导阻滞(t-CLBBB)、经典完全性左束支传导阻滞(CLBBB)和非特异性室内传导延迟(IVCD)的诊断标准,将入选患者分为t-CLBBB组(20例)、CLBBB组(15例)和IVCD组(17例)。比较3组一般临床资料、随访6个月患者的超声心动图检查[包括左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF),纽约心脏协会(NYHA)心功能分级]和6分钟步行试验(6-MWT)的变化。结果 :一般临床资料的比较:t-CLBBB组非缺血性心脏病的比例高于CLBBB组和IVCD组,差异有统计学意义(P均<0.05)。术后6个月随访结果:LVEDD和纽约心脏协会(NYHA)心功能分级在t-CLBBB组均低于CLBBB组、IVCD组[LVEDD3组分别为(62.6±8.9)mm、(70.0±8.9)mm、(72.8±8.0)mm;NYHA心功能分级3组分别为(2.00±0.45)级、(2.73±0.80)级、(3.12±0.78)级];而LVEF和6-MWT在t-CLBBB组均高于CLBBB组、IVCD组,[LVEF3组分别为(38.5±6.2)%、(31.7±6.7)%、(30.1±6.7)%;6-MWT3组分别为(302.0±57.9)m、(257.3±59.0)m、(220.2±57.9)m],3组间比较差异均有统计学意义(P均<0.05)。结论:CRT是治疗慢性心衰的一种有效的手段。不同QRS波形态的慢性心衰患者对CRT的临床疗效不同,但伴有t-CLBBB的患者对CRT有更好的反应性。Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group, n=20, Classic LBBB (CLBBB) group, n=15 and IVCD group, n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classification and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher thanthose in CLBBB group and IVCD group, all P〈0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classification in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 4- 0.78) grade. 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, all P〈0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.
