恢复期心肌梗死患者PCI治疗作用的超声评价

Ecocardiographic evaluation of the impact of PCI on the patients with myocardial infarction

目的评价心肌梗死恢复期经皮冠状动脉介入治疗(PCI)对患者近期及远期左室功能的影响。方法对30例首次心肌梗死患者于发病(5.8±2.7)周行PCI,并于术前(4.8±4.3)d、术后(4.5±2.6)d及术后(6.3±1.5)个月行心脏超声检查,观察PCI对左室容量、左室功能的影响。结果PCI组术后近期及远期左室容量较术前减小、左室收缩功能明显改善,而左室舒张功能无明显变化。结论在心肌梗死恢复期,PCI能改善患者的近期及远期左室功能。

Objective To assess the late and long-term impact of percutaneous coronary intervention （PCI） on the patient with myocardial infarction. Methods In 30 patients, successful PCI was performed （5.8 ± 2.7） weeks after acute myocardial infarction, serial echocardiographic examinations were performed before （4. 8 ± 4.3 ） days, shortly after PCI （4.5 ±2. 6） days and during follow-up （6. 3 ± 1.5） months after PCI to assess the changes in left ventricle volumes, systolic and diastolic function. Results Left ventricle volumes were decreased and systolic function was improved shortly after PCI and during follow-up, but left ventricle diastolic function was unchanged. Conclusions PCI performed during the recovery phase of acute myocardial infarction may significantly improve functional status of the patients.
