Anjitha et al. (2026) conducted a cross-sectional in Dyspnea (n=30). Cardiac cause of dyspnea vs. Pulmonary cause of dyspnea was evaluated on Mean Dyspnea Discrimination Index (DDI) score (p=<0.001). The Dyspnea Discrimination Index was significantly higher in patients with cardiac causes of dyspnea compared to pulmonary causes (16.90 vs. 5.81, p<0.001), demonstrating strong discriminative ability.
