Univariate analysis showed that the differences in the distribution of 9 variables, age, gender, RCA occlusion post-PCI, LVEF, cTnI, MYO, NTproBNP, and NYHA, were statistically significant between the patients in the HF group and the Non-HF group (all P-value < 0.05, Table 1). Here, TNNI3 is linked to hydrops fetalis.
