Central sleep apnea is common in patients with advanced heart failure. Apneic episodes are associated with hypoxemia, hypercapnia, and neurohumoral activation resulting in a rise in pulmonary vascular resistance. This case report describes a patient with a left ventricular assist device implanted for severe heart failure in whom unrecognized central sleep apnea resulted in under-filling of the left ventricle and a reduction in left ventricular assist device inflow.
中枢性睡眠呼吸暂停在晚期心力衰竭患者中很常见。呼吸暂停事件与低氧血症、高碳酸血症和神经体液激活有关,导致肺血管阻力升高。本病例报告描述了一位因严重心力衰竭植入左心室辅助装置的患者,由于未被识别的中枢性睡眠呼吸暂停导致左心室充盈不足和左心室辅助装置流入减少。
