研究目的:

主要目的:探究HFpEF患者不同运动时间对心脏舒张功能的影响 次要目的: (1)评估HFpEF患者不同运动时间对一年全因再住院率、心血管死亡率的影响 (2)评估HFpEF患者不同运动时间对运动能力的影响 (3)评估HFpEF患者不同运动时间对生活质量的影响  

Objectives of Study:

Primary Objective To investigate the effect of different exercise durations on cardiac diastolic function in patients with HFpEF. Secondary Objectives 1. To evaluate the effect of different exercise durations on 1‑year all‑cause readmission rate and cardiovascular mortality in patients with HFpEF. 2. To evaluate the effect of different exercise durations on exercise capacity in patients with HFpEF. 3. To evaluate the effect of different exercise durations on quality of life in patients with HFpEF.

First-time hospitalized patients with New York Heart Association (NYHA) functional class II or III; 4.

Invasive hemodynamic testing: resting pulmonary capillary wedge pressure (PCWP) >= 15 mmHg (1 mmHg = 0.133 kPa) or left ventricular end-diastolic pressure >= 16 mmHg, or stress PCWP >= 25 mmHg].

排除标准:
