Right ventricular (RV) dysfunction may occur in HF patients due to various factors, including adverse interventricular interactions, ischemic heart disease, and HF-correlated pulmonary hypertension. Additionally, the deterioration of RV function plays a critical role in the progression of HF, regardless of left ventricular (LV) systolic function, suggesting an unfavorable outcome. Throughout the progression of HF and increasing afterload, the right ventricle undergoes adaptive remodeling to preserve adequate cardiac output. Right ventricular-pulmonary artery (RV-PA) coupling integrates the dynamic adaptation of RV systolic function to afterload and has been considered a stronger predictor of HF prognosis than other conventional parameters. Thus, accurate evaluations of RV-PA coupling are significant in the clinical diagnosis and management of HF patients, along with prognostic speculation. In this review, we summarize the basic principles and measurements of RV-PA coupling and focus on its clinical significance across each subtype of HF.<\/jats:p>","DOI":"10.3390\/diagnostics15162083","type":"journal-article","created":{"date-parts":[[2025,8,20]],"date-time":"2025-08-20T13:18:14Z","timestamp":1755695894000},"page":"2083","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Clinical
