This study aims to evaluate the prognostic value of combining the tricuspid annular plane systolic excursion\/systolic pulmonary artery pressure (TAPSE\/sPAP) ratio with right ventricular myocardial work (RVMW) parameters in patients with PAH, to improve early risk stratification. Methods: A total of 43 PAH patients diagnosed via right heart catheterization were enrolled. Echocardiography-derived TAPSE\/sPAP ratio and RVMW parameters, including right ventricular global work efficiency (RVGWE), global work index (RVGWI), global constructive work (RVGCW), and global wasted work (RVGWW), were measured. Clinical worsening events were recorded during a median 515-day follow-up. Statistical analyses included correlation tests, Firth penalized logistic regression, receiver operating characteristic (ROC) curves, and Kaplan\u2013Meier survival analysis. Results: The TAPSE\/sPAP ratio correlated negatively with RVGCW (r = \u22120.346, p = 0.023) and RVGWW (r = \u22120.417, p = 0.005), but not with RVGWE or RVGWI. Clinical worsening events occurred in 25.6% of patients, with significantly lower TAPSE\/sPAP ratio (0.16 vs. 0.24 mm\/mmHg), RVGWE (72.0% vs. 88.5%), and RVGWI (431.0 vs. 641.0 mmHg%) in the Event group (all p &lt; 0.05). Multivariate Firth penalized logistic regression was used for combining TAPSE\/sPAP ratio with RVGWE. ROC analysis demonstrated that the combination of TAPSE\/sPAP and RVGWE yielded superior predictive power (AUC = 0.949, p &lt; 0.001) compared to individual parameters. Conclusion: Non-invasive assessment of TAPSE\/sPAP ratio and RVGWE provides significant prognostic value in PAH. Their combination enhances early risk prediction, offering a practical tool for clinical management.<\/jats:p>","DOI":"10.3390\/jcdd13070324","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T16:30:37Z","timestamp":1783701037000},"page":"324","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Combination of TAPSE\/sPAP Ratio and Myocardial Work to Assess Prognosis in Patients with Pulmonary Arterial Hypertension"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6627-6202","authenticated-orcid":false,"given":"Jian","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Cardiology, The First Affiliated Hospital of Ningbo University, Ningbo 315000, China"},{"name":"Department of Cardiology, Shanghai Jiao Tong University School of Medicine Affiliated Renji Hospital, Shanghai 200127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingying","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Intensive Care Unit, The First Affiliated Hospital of Ningbo University, Ningbo 315000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenwei","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Cardiology, The First Affiliated Hospital of Ningbo University, Ningbo 315000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanbin","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Cardiology, The First Affiliated Hospital of Ningbo University, Ningbo 315000, China"},{"name":"Ningbo Clinical Research Center for Cardiovascular Diseases, Ningbo 315000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3618","DOI":"10.1093\/eurheartj\/ehac237","article-title":"2022 ESC\/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension","volume":"43","author":"Humbert","year":"2022","journal-title":"Eur.
