According to this multivariable analysis, higher levels of acylcarnitine ratio C4/C18:2 (aHR = 1.89 [1.09, 3.29]; p < 0.01), and apoB (aHR = 1.02 [1.01, 1.04]; p = 0.01), as well as history of HF (aHR = 1.28 [1.01, 1.41]; p = 0.02), age > 65 (aHR = 1.04 [1.01, 1.05]; p = 0.04) and presence of ACS (aHR = 1.12 [1.05–1.21]; p = 0.01) were independent predictors of more frequent MACCE/repeat revascularization/cardiovascular hospitalization occurrence (Fig. 1). Here, APOB is linked to hydrops fetalis.
