| contents | Usefulness of cardiopulmonary exercise test combined with exercise stress echocardiography in mild chronic thromboembolic pulmonary disease Min Sun Kim Kina Jeon Eun Kyoung Kim Taek Kyu Park Hye Yun Park Jeong Hoon Yang Sung‐Ji Park Sang‐Chol Lee Seung Woo Park Duk‐Kyung Kim Sung‐A Chang Echocardiography AbstractPurposeChronic thromboembolic pulmonary disease (CTEPD) can lead to exercise limitations even without right ventricular (RV) dysfunction or pulmonary hypertension at rest. Combining exercise stress echocardiography with cardiopulmonary exercise testing (ESE‐CPET) for RV function and pressure changes combined measuring overall function may be useful for CTEPD evaluation. This study aims to investigate CPET and ESE results to elucidate the mechanisms of exercise limitation in mild CTEPD cases.MethodsAmong our CTEPD registry, 50 patients who performed both right heart catheterization data of mild disease (less than 30 mm Hg of mean pulmonary arterial pressure (mPAP)) and ESE‐CPET were enrolled. Echocardiography and CPET‐derived parameters were compared with hemodynamic parameters measured through right heart catheterization.ResultsPeak VO2 (maximal oxygen consumption) was decreased in overall population (71.3 ± 16.3% of predictive value). Peak VO2 during exercise was negatively correlate with mPAP and pulmonary vascular resistance at rest. A substantial increase in RV systolic pressure (RVSP) was observed during exercise (RVSP: pre‐exercise 37.2 ± 11.8 mm Hg, postexercise 64.3 ± 24.9 mm Hg, p‐value < .001). Furthermore, RV function deteriorated during exercise when compared to the baseline (RV fractional area change: 31.5 ± 10.0% to 37.8 ± 7.0%, p‐value < .001; RV global longitudinal strain: −17.1 ± 4.2% to −17.7 ± 3.3%, p‐value < .001) even though basal RV function was normal. While an excessive increase in RVSP during exercise was noticed in both groups, dilated RV and RV dysfunction during exercise were demonstrated only in the impaired exercise capacity group.ConclusionCTEPD patients with mild PH or without PH exhibited limited exercise capacity alongside an excessive increase in RVSP during exercise. Importantly, RV dysfunction during exercise was significantly associated with exercise capacity. ESE‐CPET could aid in comprehending the primary cause of exercise limitation in these patients. 10.1111/echo.15795 http://onlinelibrary.wiley.com/termsAndConditions#vor |
