中文摘要:
      目的:探讨经皮室间隔心肌化学消融术(PTSMA)最适酒精使用剂量?方法:连续选择2007年1月~2010年12月在本院接受低剂量酒精(≤ 2.0 ml)消融的肥厚梗阻型心肌病(HOCM)患者10例;按1∶2配比的病例对照研究,选择2000年1月~2006年12月接受较大剂量酒精(> 2.0 ml)消融治疗的患者20例作为历史对照组,分别评估两种治疗方案对术后早期血流动力学和心脏重构的影响?结果:低剂量和对照组术后即刻[(28.0 ± 8.8) mmHg和(27.5 ± 7.2) mmHg]?术后3个月[(29.5 ± 6.6) mmHg和(28.1 ± 5.0) mmHg]的左心室流出道压力阶差(LVOTPG)均较基线时[(69.9 ± 13.1) mmHg和(70.6 ± 13.4) mmHg]显著性下降(P < 0.01),术后室间隔厚度明显减小(P < 0.01),左心室舒张末内径无变化;而两组间术后即刻?术后3个月LVOTPG水平及下降幅度均无差异(P > 0.05);相关分析显示,酒精用量分别与术后即刻LVOTPG以及术后3个月LVOTPG?室间隔厚度和左室舒张末内径等变化无相关性(P > 0.05)?结论:小剂量酒精消融同样导致术后早期血流动力学和心脏结构的改善?
英文摘要:
      Objective: To determine the effects of various doses of alcohol in pecutaneous transluminal septal myocardial ablation (PTSMA) for obstructive hypertrophic cardiomyopathy (HOCM). Methods: A 1∶2 matched case-control study was performed in our hospital. Ten consecutive patients with HOCM were assigned to receive small dose of alcohol(≤2.0 ml),and they were compared with 20 cases receiving standard doses(> 2.0 ml). Early results of hemodynamic changes and left ventricular remodeling were determined invasively and by echocardiography before and after PTSMA. Results: In low-dose alcohol group,left ventricular outflow tract pressure gradient (LVOTPG) was (28.0 ± 8.8) mmHg immediately after PTSMA (P < 0.01),and (29.5 ± 6.6) mmHg at 3 months (P < 0.01),versus (69.9 ± 13.1) mmHg before the procedure. In standard group,LVOTPG was(27.5 ± 7.2) mmHg immediately and (28.1 ± 5.0) mmHg at 3 months after PTSMA(P < 0.01),vs(70.6 ± 13.4) mmHg before the procedure. The thickness of interventricular septum (IVS) was significantly decreased at 3 months post-PTSMA in both groups(P < 0.01). However,there were no significant differences in hemodynamic and morphologic changes between the 2 groups after PTSMA. No significant correlations were identified between the volume of ethanol injected and early hemodynamic, morphologic variables immediately or at 3 months after PTSMA either in low or standard dose of alcohol. Conclusion: Low-dose of alcohol was able to achieve the desirable degree of LVOTPG reduction and left ventricular remodeling in PTSMA.
