Abstract:

Objective To initially explore of left ventricular assisted method(left ventricular assistdevice, LVAD)on cardiopulmonary exercise test (cardiopulmonary exercise test, CPET). Methods Ananalysis of 11 patients with end-stage heart failure who underwent LVAD implantation in our hospital from October 2021to October 2022 was conducted,these patients underwent cardiopulmonary exercise test early after surgery and relevantparameters were collected for analysis. Results Among the 11 LVAD patients from October 2021 to October 2022,9 cases were males (81.8%),and the mean age was 42 years ;A total number of 7 cases were dilated cardiomyopathyand 2 cases were myocardial insufficiency,accounting for 36.4%. Preoperative echocardiography suggested that thesepatients had poor left heart function〔left ventricular ejection fraction(21.4±4.2)%,left ventricular diastolic diameter(80.6±10.4)mm〕,but the right heart function was in the normal range〔right ventricular anterior and posterior diameter(24.8±4.9)mm,(18.2±4.7)mm systolic displacement of the tricuspid annulus〕. The SWAN-GANZ catheter indicateda high pulmonary artery pressure〔pulmonary artery systolic pressure(41.5±8.7)mmHg〕. Clinical outcome: onepatient had perioperative death,and 10 patients survived well. Postoperative activity tolerance: The activity tolerancewas poor at 30 days after surgery,but activity tolerance improved significantly at 3 months,with peak oxygen uptake〔(12.9 ± 2.8)ml/(kg·min)vs(15.8 ± 1.3)ml/(kg·min),P = 0.05〕and the slope of carbon 2 ventilation effectiveness〔(42.6 ± 6.3)ml/(kg·min)vs(31.7 ± 6.6)ml/(kg·min),P = 0.001〕. Conclusion LVAD is an effective means totreat end-stage heart failure and can significantly improve the activity tolerance in patients with heart failure.

摘要:

目的 通过心肺运动试验(cardiopulmonary exercise test,CPET)对终末期心力衰竭患者左心室辅助(left ventricular assist device,LVAD)术后运动能力恢复的情况进行初步探索。方法 回顾性分析2021 年 10 月至 2022 年 10 月,于阜外华中心血管医院接受 LVAD 植入术的 11 例终末期心力衰竭患者,这部分患者术后早期进行心肺运动试验检查并收集相关参数进行分析。结果 2021 年 10 月至 2022 年 10 月完成的 11 例 LVAD 患者中,男性为 9 例占比 81.8%,平均年龄为 42 岁 ;病因方面主要为扩张型心肌病 7 例和心肌致密化不全 2 例,占比 81.8% ;4 例患者为 IABP 过渡至 LVAD,占比 36.4%。术前超声心动图提示这部分患者左心功能较差〔左心室射血分数(21.4±4.2)%,左室舒张末径(80.6±10.4)mm〕,但右心功能处于正常范围〔右室前后径(24.8±4.9)mm,三尖瓣环收缩期位移(18.2±4.7)mm〕。SWAN-GANZ 导管提示肺动脉压力偏高〔肺动脉收缩压(41.5±8.7)mmHg,1 mmHg = 0.133 kPa〕。临床结局方面 :1 例患者出现围手术期死亡,10 例患者存活良好。术后活动耐量方面 :术后 30 d 时活动耐量较差,但术后 3 个月时活动耐量均有明显改善,其中峰值摄氧量显著提高〔(12.9±2.8)ml/(kg·min)比(15.8±1.3)ml/(kg·min),P = 0.05〕,二氧化碳通气有效性斜率显著下降〔42.6±6.3)ml/(kg·min)比(31.7±6.6)ml/(kg·min),P = 0.001〕。结论 LVAD 是治疗终末期心力衰竭的有效手段,能够显著改善心衰患者的活动耐量。
