ACE and diabetes mellitus: Variables associated with a higher frequency of HF hospitalizations were hypertension, diabetes, atrial fibrillation, previous HF, abnormal electrocardiogram, lower diastolic blood pressure values, glomerular filtration rate, and HDL cholesterol, higher triglyceride values, as well as lower prescription of antiplatelet and lipid-lowering therapy, and greater use of HF-related drugs (Table 2); in the case of AMI, only lower treatment with angiotensin-converting enzyme inhibitors or receptor antagonists was significant in the univariate analysis (Table 3).
