Table 2. Baseline echocardiographic parameters and their relationships with RV function using the speckle-tracking strain technique
Figure 3. Estimated mPAP during exercise between patients with and without RV dysfunction in the entire cohort. mPAP, mean pulmonary artery pressure; RV, right ventricular
