ACE, angiotensin-converting enzyme; ARB, angiotensin receptor blocker; BMI, body mass index; DM, diabetes mellitus; FPG, fasting plasma glucose; HbA1c, glycated haemoglobin A1c; HDL-C, high-density lipoprotein cholesterol; IGR, impaired glucose regulation; MI, myocardial infarction; NGR, normal glucose regulation; OGTT, oral glucose tolerance test.
