Right ventricular (RV) dysfunction is common and linked to poor outcomes across conditions such as heart failure (HF), acute coronary syndromes, pulmonary embolism, and pulmonary hypertension. While imaging, electrocardiogram (ECG), and invasive tests remain central to RV assessment, circulating biomarkers offer a rapid, non-invasive, and reliable alternative. These biomarkers reflect key pathophysiological processes, including myocardial injury, stress, fibrosis, inflammation, congestion, and multiorgan involvement. High-sensitivity troponins and natriuretic peptides (BNP, NT-proBNP) are already widely used, while emerging biomarkers—such as CA125, copeptin, galectin-3, and others—may enhance diagnostic accuracy and risk stratification. Some, like CA125 and NT-proBNP, have shown promise in guiding post-discharge therapy. However, challenges remain regarding the specificity of biomarkers for RV dysfunction and their role across different clinical contexts. This review provides an integrated overview of RV dysfunction, with a focus on the diagnostic and therapeutic potential of both established and novel biomarkers.
