Results LAD, RVBD, E/e′, LVEDD, and LVEDV values in the CPD and n-CPD groups were significantly higher than those in the control group, and E/A and EDT in the CPD and n-CPD groups were significantly lower than those in the control group (t=5.12, 3.67, 7.29, 5.69, 5.89, 3.15, 2.05, 5.89, 5.22, and 3.83, P<0.01). Compared with the n-CPD group, LAD and E/e′ values were significantly higher and E/A was significantly lower in the CPD group (t=8.12, 3.24, and 3.94, respectively, P<0.001). Compared with the healthy control group, QRS, LVEDD, LVESD, LVEDV, LVESV, IVMD, b-Ssl, m-Ssl, and SDt values were significantly higher and LVEF, Sept-LS, Lat-LS, and GLS values were significantly lower (t=20.38, 7.17, 7.35, 6.50, 5.86, 10.24, 7.15, 6.35, 11.24, 10.99, 5.92, and 6.12, respectively; P<0.001) in the CPD group; QRS, LVEDD, LVESD, LVEDV, LVESV, IVMD, b-Ssl, m-Ssl, and SDt values were significantly higher and LVEF, Sept-LS, Lat-LS, and GLS values were significantly lower (t=16.54, 1.99, 2.12, 2.07, 5.87, 2.53, 2.10, 5.06, 2.68, 3.66, 2.06, and 3.62, respectively, P<0.05) in the n-CPD group. Compared with the n-CPD group, QRS, LVEDD, LVESD, LVEDV, LVESV, IVMD, b-Ssl, m-Ssl, and SDt values were significantly higher and LVEF, Sept-LS, Lat-LS, and GLS values were significantly lower (t=4.68, 5.96, 6.63, 5.32, 5.01, 5.10, 5.28, 4.86, 7.16, 4.74, 7.20, 3.78, and 3.57, respectively, P<0.001) in the CPD group. Further, patients with LVEF > 50% were selected for comparisons, and there was no significant difference in LVEF between the two groups (P>0.05). Compared with the healthy control group, QRS, LVEDD, LVESD, LVEDV, LVESV, IVMD, b-Ssl, m-Ssl, and SDt values were significantly higher and Sept-LS, Lat-LS, and GLS values were significantly lower (t=19.44, 4.01, 5.21, 5.61, 4.73, 9.19, 5.27, 3.16, 3.25, 8.02, 4.15, and 5.42, respectively, P<0.001) in the CPD group; QRS, LVEDD, LVEDV, LVESV, IVMD, b-Ssl, m-Ssl, and SDt values were significantly higher and Sept-LS and GLS values were significantly lower (t=20.68, 2.46, 3.15, 3.10, 6.95, 3.00, 4.59, 6.53, 3.84, and 4.05, respectively, P<0.05) in the n-CPD group. Compared with the n-CPD group, QRS, LVEDD, LVESD, LVEDV, LVESV, IVMD, b-Ssl, and SDt values in CPD group were significantly higher and Sept-LS, Lat- LS, and GLS values were significantly lower (t=2.73, 2.13, 3.88, 3.06, 2.19, 3.94, 3.00, 3.25, 4.38, 2.90, and 2.30, respectively, P<0.05l) in the CPD group.
