Cardiopulmonary exercise testing (CPET) combined with exercise echocardiography (CPETecho) allows simultaneous assessments of cardiac, pulmonary, and ventilation in heart failure (HF) with preserved ejection fraction (HFpEF). This study sought to determine whether simultaneous assessment of CPET variables could provide additive predictive value over exercise stress echocardiography in patients with dyspnoea.

心肺运动试验与同时运动超声心动图在射血分数保留的心力衰竭中的预后效用


心肺运动试验 (CPET) 与运动超声心动图 (CPETecho) 相结合，可以同时评估射血分数保留 (HFpEF) 的心力衰竭 (HF) 患者的心脏、肺和通气情况。本研究旨在确定 CPET 变量的同时评估是否可以为呼吸困难患者提供相对于运动负荷超声心动图的附加预测价值。
