Survival curves comparing patients with normal and dilated RV. Dilated RV showed poorer survival compared with the normal RV group, with mean survival of 69.0 months and 103.2 months, respectively, using log-rank test (p = 0.026). However, further analysis with Cox regression did not detect any statistically significant difference with HR of 7.54 (p = 0.059). HR = hazard ratio. RV = right ventricle.
