Research advances in application of 6-min walk test in patients with pulmonary hypertension
The 6-min walk test(6MWT)is an effective tool to assess the cardiopulmonary function and exercise tolerance,and is widely used in clinical practice to assess the exercise capacity in the patients with car-diopulmonary disease.Pulmonary hypertension(PH)is a serious cardiovascular disease manifested by a con-tinuous increase in pulmonary circulatory pressure,which limits the right heart function and eventually devel-ops into the right heart failure,moreover its clinical manifestations lack specificity,making diagnosis difficult.With the development of PH diagnosis and treatment technology,the medical staffs have paid more and more attention to the application of 6MWT in the diagnosis,treatment and prognosis of the patients with PH.This article reviews the characteristics of 6MWT,its application in PH,and its limitations and future prospects in order to help clinic to better understand the role of 6MWT in the whole disease course of the patients with PH,and encourage the medical care staffs to broadly apply and improve 6MWT to make it to be more reliable clinical evidence.
