The international diabetes and nephrology community recommends that diabetic patients should have intensive blood pressure control should be below 130/80 mm Hg. The January 2014 US hypertension guidelines relaxed the blood pressure control goal to below 140/90 mm Hg for diabetics under 60 years of age and to below 150/90 mm Hg for diabetics over 60 years of age. This goal change caused resistance from the international diabetes and nephrology community, arguing that this goal was detrimental to the control of diabetes complications. Many national or regional hypertension guidelines issued after this time, such as the latest hypertension guidelines from Japan, the United Kingdom, and Canada, set the blood pressure control goal for diabetic patients at less than 130/80 mmHg. Combining these, the current guidelines in China are a compromise of blood pressure control below 140/90 mmHg for general patients and 130/80 mmHg for younger diabetic patients and patients with comorbid renal disease. Personally, I think this goal is also more appropriate, but of course, it is also necessary to determine the program in the context of the individual situation of diabetic patients. Diabetes expert tips: 1. The blood pressure of diabetic patients should be controlled below 130/80mmHg; 2. Diabetic nephropathy can be diagnosed with a history of diabetes for more than 5 years, urinary microprotein and also diabetic fundus lesions; 3. The treatment of diabetic nephropathy is based on blood pressure control. Antihypertensive drugs should be preferred to sartan antihypertensive drugs, and the dose should be doubled. Also use long-acting calcium antagonists such as amlodipine and diuretics in combination.
