The biggest threat of diabetes is to increase the occurrence of cardiovascular diseases (such as coronary heart disease, myocardial infarction, stroke, etc.). Many diabetic patients only focus on their blood sugar, ignoring or not paying enough attention to blood pressure and blood lipids, which is not okay! Blood pressure management Blood pressure in diabetic patients should be controlled below 130/80mmHg to reduce the occurrence of adverse cardiovascular events. For those with combined diabetic nephropathy and urinary protein, blood pressure should be controlled below 125/75mmHg. However, in patients of advanced age, poor general condition or short life expectancy, overly strict blood pressure control may not provide additional benefit, and blood pressure control below 140/90 mmHg is sufficient. The choice of antihypertensive drugs is preferred to ACEI (representative drugs such as benazepril, perindopril, etc.) or ARB (representative drugs such as valsartan, cloxacin, etc.), and most of the blood pressure cannot reach the target, so calcium antagonists (representative drugs such as nifedipine controlled-release tablets, felodipine extended-release tablets, etc.) or diuretics (representative drugs such as hydrochlorothiazide) can be used in combination. Lipid management Patients with coexisting cardiovascular disease (e.g., coronary artery disease, cerebral infarction, etc.) should receive statin therapy to control low-density lipoprotein cholesterol (LDL-C) below 1.8 mmol/L, regardless of their lipid levels. Patients without cardiovascular disease but ≥40 years of age, control LDL-C below 2.6 mmol/L. In addition, if not contraindicated, all diabetic patients with comorbid cardiovascular disease should take low-dose aspirin (75-150 mg/d). Finally, it is important that diabetic patients take their medication under the guidance of a regular hospital doctor, and that they do not purchase medication or change their treatment plan on their own, let alone blindly believe in prescriptions.
