Starting from these observations, in our study, by analyzing the relationship between these indexes and the TTE parameters characterizing LVF, RVD, and DD, we evidenced statistically significant correlations (p < 0.0001) for all of them, but especially for the TyG index, the number of elements defining MS, the level of inflammation (as expressed by the initial CRP values), and the post-acute COVID-19 condition gravity (as quantified by the PCFS scale). Here, CRP is linked to COVID-19.
