PON1 and Shock: In the COX’s multivariate analysis when all above-mentioned factors including the PON1 L55M genotypes were included, it has appeared that only the presence of cardiogenic shock (p = 0.015) and of the AV block (p = 0.018) remained significant independent prognostic factors (Table 7); TVD had a marginal significance as an unfavorable independent factor (p = 0.056), while all other factors have lost their role (Table 8).
