摘要
目的:探讨球囊支架对吻技术(BSKT)和拘禁导丝技术(JWT)在冠状动脉左前降支-对角支真性分叉病变患者中应用的疗效。方法:连续性入选2022年1月至2024年1月在石家庄市人民医院心内科住院的203例伴左前降支-对角支真性分叉病变的不稳定性心绞痛患者,所有患者采用BSKT或JWT术式进行治疗并完成6个月随访。根据住院号单双号分组,其中单号入组BSKT组(n=107),双号入组JWT组(n=96)。观察两种术式的安全性、有效性和心肌灌注指标。结果:BSKT组和JWT组术后即刻最小管腔面积、术后6个月加拿大心血管学会心绞痛分级、术后6个月静息+负荷心肌灌注总评分、静息+负荷心肌缺血总节段数、异常心肌灌注范围均显著优于术前,差异均有统计学意义(P均<0.05)。BSKT组支架置入即刻成功87例(81.3%),JWT组64例(66.7%),BSKT组显著优于JWT组;BSKT组术后1 d心肌肌钙蛋白I[(0.22±0.13)ng/ml vs.(0.45±0.27)ng/ml,P<0.001]、肌酸激酶同工酶[(35.24±13.15)U/L vs.(42.39±21.66)U/L,P=0.004]、B型利钠肽[(133.52±25.62)pg/ml vs.(167.22±22.04)pg/ml,P<0.001]均低于JWT组;术后6个月BSKT组的负荷心肌缺血总节段数[(3.23±1.54)节vs.(3.87±1.62)节,P=0.004]、负荷心肌灌注总评分[(4.18±2.21)分vs.(4.97±2.96)分,P=0.031]、异常心肌灌注范围[(7.04±3.27)%vs.(8.24±3.69)%,P=0.014]均低于JWT组,差异均有统计学意义。结论:BSKT和JWT两种术式均可显著改善左前降支-对角支真性分叉病变患者的心功能、心肌损伤和心肌灌注,BSKT术式对分支血管的保护作用较JWT术式更充分。
Objectives:To explore the therapeutic efficacy of balloon stent kissing technique(BSKT)and jailing wire technique(JWT)in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch of the coronary artery,and to observe the impact of these two interventional procedures on the lumen area,angina symptoms,cardiac function,myocardial injury,and myocardial perfusion of patients.Methods:A retrospective analysis was conducted in 203 patients with true bifurcation lesions of the left anterior descending branch-diagonal branch who underwent BSKT and JWT procedures and completed a 6-month follow-up in the Department of Cardiovascular Medicine at Shijiazhuang People's Hospital from January 2022 to January 2024.Patients were randomly assigned to the BSKT group(n=107)or the JWT group(n=96).The safety,efficacy,and myocardial perfusion indicators of the two groups were compared.Results:The minimum lumen area measured by intravascular ultrasound immediately after procedure,the Canadian Cardiovascular Society angina classification at 6 months post-intervention,the total score of resting+stress myocardial perfusion at 6 months post-intervention,the total number of segments with resting+stress myocardial ischemia,and the abnormal myocardial perfusion area in both the BSKT group and JWT group were significantly improved compared to baseline values(all P<0.05).In the BSKT group,87 cases(81.3%)achieved immediate success in stent placement,whereas in the JWT group,64 cases(66.7%)achieved immediate success in stent placement.The BSKT group significantly outperformed the JWT group.In terms of the myocardial injury and cardiac function indicators assessed on postoperative day 1,the cardiac troponin I level([0.22±0.13]ng/ml vs.[0.45±0.27]ng/ml,P<0.001),creatine kinase MB([35.24±13.15]U/L vs.[42.39±21.66]U/L,P=0.004),and B-type natriuretic peptide([133.52±25.62]pg/ml vs.[167.22±22.04]pg/ml,P<0.001)were all significantly lower in the BSKT group than in the JWT group.In terms of the myocardial perfusion indicators at 6 months post-intervention,the number of ischemic segments under stress(3.23±1.54 vs.3.87±1.62,P=0.004),the total score of stress perfusion(4.18±2.21 vs.4.97±2.96,P=0.031),and the abnormal myocardial perfusion area([7.04±3.27]%vs.[8.24±3.69]%,P=0.014)were all significantly lower in the BSKT group than in the JWT group.Conclusions:Both BSKT and JWT procedures can significantly improve the lumen area of the left anterior descending branch,angina symptoms,and myocardial perfusion in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch.The BSKT procedure provides more adequate protection for the bifurcation vessels compared to the JWT procedure.
