Registry for Chronic Obstructive Pulmonary Disease With Pulmonary Thromboembolism in China

The Study of Early Detection, Disease Course and Prognosis of Pulmonary Thromboembolism in Chronic Pulmonary Hypertension

Chronic obstructive pulmonary disease (COPD) is closely related to venous thromboembolism (VTE). But it is difficult to identify VTE in COPD patients in clinical practice. Therefore, the prevalence data of PTE in COPD is limited. Pulmonary thromboembolism (PTE) is an important factor effecting patients outcomes, but existing researches only have short follow-up time less than 1 year. This study aim to develop an early detection system of PTE in COPD and explore the disease course and prognosis.

Inclusion Criteria:

• Patients hospitalized for chronic obstructive pulmonary disease (COPD) exacerbation

Exclusion Criteria:

• Stable COPD patients
• COPD hospitalized for definite causes other than pulmonary thromboembolism
• Patients with malignant tumor
• Patients with contraindications for CT pulmonary angiography
• Psychopath
