BACKGROUND
It remains unknown whether patients with severe decompensated class IV heart failure (HF) receiving intravenous inotropic treatment benefit from cardiac resynchronization therapy (CRT).
METHODS
We identified patients who underwent urgent CRT implantation due to decompensated class IV HF necessitating intravenous inotropic therapy.
RESULTS
Of 10 patients with chronic ischemic cardiomyopathy (median QRS duration of 170 ms), CRT implantation was associated with symptomatic improvement in 8 patients. The mortality rate was 50% during a median follow-up of 9.5 months, with a median CRT-to-death duration of 6 months.
CONCLUSIONS
CRT was feasible among class IV patients receiving inotropic treatment and was associated with clinical improvement.
背景
因严重失代偿性IV级心力衰竭（HF）接受静脉注射正性肌力药物治疗的患者是否能从心脏再同步治疗（CRT）中获益仍不清楚。
方法
我们确定了因失代偿性IV级HF需要静脉注射正性肌力药物治疗而接受紧急CRT植入的患者。
结果
在10例慢性缺血性心肌病患者（QRS时限中位数为170毫秒）中，CRT植入使8例患者症状改善。在中位随访9.5个月期间，死亡率为50%，从CRT到死亡的中位持续时间为6个月。
结论
CRT在接受正性肌力药物治疗的IV级患者中是可行的，且与临床改善相关。
