Simplified risk stratification based on cardiopulmonary exercise test: A Spanish two‐center experience
Abstract A simplified 4‐strata risk stratification approach based on three variables is widespread in pulmonary arterial hypertension (PAH) at follow‐up. This study aimed to assess the impact of replacing the 6‐min walk test (6MWT) with the peak 02 uptake evaluated by the cardiopulmonary exercise te...

description | Abstract A simplified 4‐strata risk stratification approach based on three variables is widespread in pulmonary arterial hypertension (PAH) at follow‐up. This study aimed to assess the impact of replacing the 6‐min walk test (6MWT) with the peak 02 uptake evaluated by the cardiopulmonary exercise test (CPET) on risk stratification by this scale. We included 180 prevalent patients with PAH from two reference hospitals in Spain, followed up between 2006 and 2022. Patients were included if all the variables of interest were available within a 3‐month period on the Spanish Registry of Pulmonary Arterial Hypertension (REHAP): functional class (FC); NT‐proBNP; 6MWT; and CPET. The original 4‐strata model (NT‐proBNP, 6MWT, FC) identified most patients at low or intermediate‐low risk (36.7% and 51.1%, respectively). Notably, the modified scale (NT‐proBNP, CPET, FC) improved the identification of patients at intermediate‐high risk up to 18.9%, and at high risk up to 1.1% in comparison with the previous 12.2% and 0.0% in the original scale. This new model increased the number of patients correctly classified into higher‐risk strata (positive NRI of 0.06), as well as classified more patients without events in lower‐risk strata (negative NRI of 0.04). The proposed score showed a slightly superior prognostic capacity compared with the original model (Harrel's C‐index 0.717 vs. 0.709). Using O2 uptake instead of distance walked in the 6MWT improves the identification of high‐risk patients using the 4‐strata scale. This change could have relevant prognostic implications and lead to changes in the specific treatment of PAH. |
