About this trial

This study aims to evaluate the clinical efficacy of non-invasive ventilation (NIV) in treating patients with high-altitude polycythemia (HAPC).

Participants will be enrolled according to the international diagnostic criteria for high-altitude polycythemia. The study will use both retrospective cohort and prospective study methods.

All participants will receive standard basic care. In addition, the intervention group will receive non-invasive ventilation treatment using either BiPAP or CPAP mode.

Key measurements, including routine blood tests, liver function, renal function, uric acid, blood lipid profile, electrocardiogram and echocardiography, will be collected as primary and secondary outcome measures to assess the effects of the treatment.

Trial outcomes

Primary outcomes

1

Change in Hemoglobin (Hb) Concentration

The primary endpoint is the absolute change in blood hemoglobin concentration (g/dL) from baseline to 3-month and 6-month follow-up. A reduction in hemoglobin level is defined as a clinically significant improvement in high altitude polycythemia status.

Time frame
Baseline, 3 months, 6 months after treatment initiation

Secondary outcomes

1

Change in Serum uric acid and blood lipid levels

Changes in serum uric acid, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) will be measured.

Time frame
Baseline, 6 months
