APOA1 and hydrops fetalis: In non-diabetic patients with HF, arylesterase activity was associated inversely with ages (r = −0.371, P < 0.001), and positively with levels of HDL cholesterol (r = 0.270, P = 0.002) and apoA-I (r = 0.257, P = 0.004), all of which were attenuated in diabetic subjects (Table 2).
