In recent years, although the prevalence of PRISm in the population has been confirmed by some studies, in-depth discussion and research in related fields are still insufficient. Previous studies have found that PRISm population can be caused by a variety of risk factors. And compared with those with normal lung function, the risk of progression to the COPD, the risk of cardiovascular-related mortality and all-cause mortality is significantly increased. Without timely intervention, it may gradually deteriorate to COPD. So it is very important to detect and prevent PRISm early. This review encapsulates research pertaining to PRISm, spanning its incidence, risk factors, disease characteristics, associated diseases, prognosis and treatment, aiming to understand PRISm comprehensively, and hope to provide more accurate condition assessment for PRISm patients, and promote the comprehensive rehabilitation and health management of patients.展开更多
