[摘要] 目的 探討超聲心動圖預測慢性收縮性心力衰竭(心衰)預后的價值。 方法 2014年8月—2016年2月方便選擇在首都醫(yī)科大學密云教學醫(yī)院診治的慢性收縮性心衰患者112例,所有患者都給予超聲心動圖檢查,記錄相關指標。同時調(diào)查患者的病例資料并隨訪預后。結(jié)果 隨訪2年,112例患者的惡性心律失常、腦卒中、心源性死亡、再次心衰、再發(fā)冠脈事件等MACE發(fā)生率為18.8%。MACE組患者的LVEDV、LVESV值顯著高于非MACE組患者[(107.33±22.19)mL vs (97.20±13.10)mL(t=6.922), (49.20±11.49)mL vs (41.02±5.66)mL(t=7.043),P<0.05)],兩組患者LVDs、LVDd、LAD值對比差異無統(tǒng)計學意義(P>0.05)。在112例患者中,直線相關分析顯示患者預后MACE與LVEDV、LVESV值成相關性,差異有統(tǒng)計學意義(P<0.05)。 結(jié)論 超聲心動圖在慢性收縮性心衰患者中的應用可反映患者的心功能狀況,預測預后具有很好的價值。

[Abstract] Objective To investigate the value of echocardiography in predicting the prognosis of chronic systolic heart failure (heart failure). Methods From August 2014 to February 2016, 112 patients with chronic systolic heart failure who were diagnosed and treated at Miyun Teaching Hospital of Capital Medical University were conveniently selected. All patients were given echocardiography and related indicators were recorded. At the same time, the patient's medical records were investigated and the prognosis was followed up. Results During the follow-up of two years, the incidence of MACE in 112 patients with malignant arrhythmia, stroke, cardiogenic death, recurrent heart failure, and recurrent coronary events was 18.8%. The LVEDV and LVESV values of the patients in the MACE group were significantly higher than those in the non-MACE group (107.33±22.19)mL vs (97.20±13.10)mL(t=6.922), (49.20±11.49)mL vs (41.02±5.66)mL(t=7.043, P<0.05)]. There was no statistically significant difference in the values of LVDs, LVDd and LAD between the two groups (P>0.05). In 112 patients, linear correlation analysis showed that the prognosis of patients with MACE was associated with LVEDV and LVESV values,the difference was statistically significant(P<0.05). Conclusion The application of echocardiography in patients with chronic systolic heart failure can reflect the cardiac function of patients and predict the prognosis is of great value.

慢性收縮性心力衰竭(心衰)是各種心血管疾病的終末階段,臨床上主要表現(xiàn)為左心室增大、左心室收縮末期容量增加,其病死率是一般人群的4~8倍[1-2]。特別是很多患者的臨床表現(xiàn)多樣,有或無呼吸困難、乏力和液體潴留(水腫)等癥狀,導致臨床診斷比較困難,預測預后也更加困難[3-5]。當前慢性收縮性心衰的診斷方法比較多,包括胸部X光片、核磁共振、放射性核素檢查、超聲心動圖、心衰標志物、心肺運動實驗等,其中超聲心動圖在準確評價心臟功能方面有很好的價值,具有無創(chuàng)、簡便的優(yōu)點[6-7]。2014年8月—2016年2月,該文具體探討了超聲心動圖預測112例慢性收縮性心衰患者預后的價值,現(xiàn)報道如下。
