ACE and hydrops fetalis: After adjusting for variables that are associated with HF hospitalization: gender, age, EF, weight, potassium, creatinine clearance, sodium, valvular diseases, CRTD implantation, ACE inhibitors, ARBs, thiazide-like diuretics, beta-blockers, aldosterone antagonists, digoxin, intravenous diuretic use, and home diuretics dose, the HF hospitalization within 1 month did not differ significantly between the two groups (aHR = 0.72, 95% CI 0.23–2.3, p = 0.57) as demonstrated in Fig. 1.
