- Prognostic impact of right atrial strain in systemic lupus erythematosus with pulmonary arterial hypertension Jie Hu Yan Deng Ping Dai Dong‐Wei Xie Wei‐Fang Lan Xiao‐Lan Tan Echocardiography AbstractObjectiveThe aim of this study was to assess right atrial (RA) function, including RA phase strain, via speckle‐tracking echocardiography (STE) in a cohort of systemic lupus erythematosus (SLE) patients with pulmonary arterial hypertension (PAH) and in particular to explore the relationship between RA phase strain and the occurrence of cardiovascular events.MethodsSTE analyses of RA function were evaluated in patients with SLE‐PAH and in 33 healthy control subjects. Clinical associations, serum biomarkers, echocardiographic data, survival times, and adverse cardiovascular events were evaluated.ResultsA total of 66 patients with SLE‐PAH were enrolled; they were divided into two groups based on the occurrence of adverse clinical events. RA phase strain was significantly reduced in patients with events than in patients without events. The endpoint was defined as the combined outcome of all‐cause mortality, right heart failure, and rehospitalization due to disease progression. During a mean follow‐up of 17.2 ± 9.9 months, 23 patients (35%) reached the endpoint. Compared with patients with RA reservoir strain (RASr) ≥33.45%, patients with RASr < 33.45% had more adverse long‐term outcomes (log rank p < .0001). RASr was independently associated with adverse clinical outcomes according to multivariate analysis (p = .010).ConclusionOur data suggest that RA function has prognostic value for SLE‐PAH patients, and strain analysis revealed that the worse the RA function is, the worse the prognosis. 10.1111/echo.15921 http://onlinelibrary.wiley.com/termsAndConditions#vor
