- Abstract: OBJECTIVE: To compare the predictive value of Ees/Ea in patients with pulmonary arterial hypertension based on right cardiac catheterization and cardiac magnetic resonance examination. METHODS: A total of 50 pulmonary arterial hypertension patients confirmed by right heart catheterization were retrospectively reviewed and followed up 2 years. The relationship between the baseline clinical data and survival prognosis of patients with pulmonary arterial hypertension were analyzed. The predictive value of baseline Ees/Ea for prognosis in patients with pulmonary arterial hypertension were compared. RESULTS: The Ees/Ea calculated by volume method was significantly correlated with the prognosis of patients with pulmonary arterial hypertension(OR =0.082, 95%CI 0.009-0.814, P=0.032). The two-year survival rate of group Ees/Ea>0.67 was significantly higher than that of Ees/Ea≤0.67(86.7% vs. 50%, P=0.003). Conclution Ees/Ea calculated by volume method is an independent influence factor of the survival prognosis of patients with pulmonary arterial hypertension. When Ees/Ea≤0.67, the patients with pulmonary arterial hypertension is more likely to deteriorate.
