Diabetes and hypertension are a difficult pair of brothers and sisters, and the two are extremely close. The prevalence of hypertension in diabetic patients is not only very high, about twice as high as in non-diabetic people, and increases with age, weight gain and disease duration, and is higher in women than in men. Foreign data show that the prevalence of hypertension in diabetic patients is 40% to 80%; in addition, hypertension occurs early in the diabetic population, with the peak of hypertension about 10 years earlier than in the non-diabetic population. The increase in blood pressure triggers and aggravates the degree of coronary atherosclerosis and increases the incidence of coronary heart disease; the atherosclerosis of large and medium-sized arteries (including carotid arteries, aorta, coronary arteries, renal arteries, etc.) appears earlier and increases in degree; the increase in blood pressure causes systemic microangiopathy in addition to macrovascular disease; the increase in blood lipids and abnormal coagulation function (increased fibrinogen inhibitory factor activity) in diabetes make The presence of hypertension will trigger and accelerate the development of diabetic nephropathy, and the accelerated progress of diabetic nephropathy will cause a further increase in blood pressure, forming a vicious circle; in recent years, scholars at home and abroad have conducted various studies on the relationship between these two diseases, and have explored the mechanism of their mutual influence in greater depth. and proposed new treatment options for diabetes mellitus complicated by hypertension. In the latest issue of Diabetes Care (September 2017), a recent statement from the American Diabetes Association (ADA) was published, updating the recommendations for the evaluation and treatment of hypertension in patients with diabetes. The statement prompts us to: Blood pressure control goals for patients with diabetes mellitus with hypertension The vast majority of patients with diabetes mellitus with hypertension have a blood pressure control goal of <140 mmHg systolic and <90 mmHg diastolic; for patients at high risk for cardiovascular disease, blood pressure can be controlled to a lower goal, such as <130/80 mmHg, provided they do not have an excessive treatment burden in reaching this goal . Lifestyle interventions Among the therapeutic measures for diabetes mellitus with hypertension, particular emphasis is placed on lifestyle interventions. For patients with systolic blood pressure >120 mmHg or diastolic blood pressure >80 mmHg, strict weight control is mandatory, and those who are overweight or obese should have their weight controlled to a safe range as soon as possible. A DASH (Dietary Approaches to Stop Hypertension) diet regimen is recommended, including salt reduction and increased potassium intake; increased fruit and vegetable intake; avoidance of excessive alcohol consumption; and increased exercise. Precise recommendations are also made on how to choose blood pressure medications based on blood pressure and proteinuria status.
