Statistical Analysis
All data were statistically analyzed using SPSS version 27.0 software. Continuous variables are presented as mean ± standard deviation (SD), while categorical variables are expressed as frequencies (%). For normally distributed continuous variables with homogeneity of variance, one-way analysis of variance (ANOVA) was conducted for comparison among multiple groups, with post hoc pairwise comparisons performed using the LSD method. Non-parametric tests were employed for variables with unequal variances. Group comparisons for categorical variables were assessed using the chi-square test.When comparing RVFWLS and RVGLS, absolute values were utilized to negate the influence of negative values on magnitude. The reproducibility of right ventricular function parameters was evaluated in a randomly selected subset of 30 patients using the intraclass correlation coefficient (ICC). Statistical significance was set at a two-tailed of P < 0.05.
