Continuous variables are presented as means ± standard deviations (SDs); differences between groups were compared using Student’s t-test. Categorical variables are presented as numbers (with percentages); differences between groups were compared using Fisher’s exact probability test. The stages of heart failure were those of the New York Heart Association (NYHA) Functional Classification. For abbreviations, please see Table 1.
