Management of Patients with Hypertension and Diabetes

Introduction to Hypertension and Diabetes Management

The American Diabetes Association recommends that patients with hypertension (160/90 mmHg) and diabetes (blood sugar 300 mg/dL) should receive immediate pharmacological therapy along with lifestyle modification to reduce the risk of cardiovascular mortality and morbidity 1, 2
A 50-year-old male patient with a blood pressure of 160/90 mmHg and blood sugar 300 mg/dL has a high cardiovascular risk 1, 2

The target blood pressure for patients with diabetes is <130/80 mmHg 1, 2
With a blood pressure of 160/90 mmHg, patients require immediate initiation of pharmacological therapy along with lifestyle modification 1, 3

Patients with blood pressure ≥160/100 mmHg should immediately start and titrate two drugs or a single combination drug 1, 4
The first-line choice is an ACE inhibitor or an angiotensin receptor blocker (ARB) 5, 6
Combination with a thiazide-like diuretic is recommended as second-line therapy 1, 3
If the blood pressure target is not achieved, a dihydropyridine calcium channel blocker can be added 3, 7
Renal function and serum potassium levels should be monitored within the first 3 months after starting ACE inhibitors, ARBs, or diuretics 6

The target glycemic control should be individualized, with an HbA1c <7% as a general target to reduce microvascular complications 2
With a blood sugar level of 300 mg/dL, patients require immediate pharmacological therapy 2

The DASH diet (Dietary Approaches to Stop Hypertension) is recommended 1, 2
Limit sodium intake (<2,300 mg/day) 8
Increase consumption of fruits, vegetables (8-10 servings per day), and low-fat dairy products (2-3 servings per day) 1, 4
Total fat intake should be moderate (25-35% of total calories) and mostly consist of monounsaturated or polyunsaturated fats 8
Adequate dietary fiber intake (14 g per 1,000 calories consumed) is recommended 8

At least 150 minutes of moderate-intensity aerobic physical activity or at least 90 minutes of high-intensity aerobic exercise per week is recommended 8, 9
Physical activity should be distributed over at least 3 days per week, with no more than 2 consecutive days without physical activity 8

A weight loss target of 5-10% of initial body weight is recommended for overweight patients 1
For long-term maintenance of significant weight loss, a greater amount of exercise (7 hours of moderate- or high-intensity aerobic physical activity per week) may be helpful 8

Blood pressure should be measured at every routine diabetes visit 1
Renal function and serum potassium levels should be monitored within the first 3 months after starting ACE inhibitors, ARBs, or diuretics 6
Lipid profiles should be measured at least once a year and more frequently if necessary to achieve targets 9
If blood pressure targets are not achieved despite multi-drug therapy, referral to a specialist in the care of patients with hypertension is recommended 6
