Abstract
Hypertension remains a major contributor to cardiovascular and renal complications in patients with diabetes mellitus, increasing the risk of macrovascular and microvascular disease. The 2025 AHA/ACC hypertension guidelines maintain a diagnostic and treatment threshold of 130/80 mmHg, emphasizing earlier and more intensive blood pressure control to reduce cardiovascular events, stroke, heart failure, and progression of diabetic nephropathy. Evidence from clinical trials and meta-analyses supports the benefits of tighter blood pressure targets, while acknowledging potential risks such as hypotension, electrolyte disturbances, and acute kidney injury. Management strategies combine pharmacologic therapy with lifestyle interventions including dietary modification, physical activity, weight management, and smoking cessation. Individualized blood pressure targets are recommended for older or frail patients to balance safety and benefit. Home and ambulatory blood pressure monitoring are highlighted for detecting masked or nocturnal hypertension, enhancing risk stratification, and supporting treatment titration. The guidelines also emphasize integrated risk assessment and multidisciplinary management. The 2025 AHA/ACC hypertension guidelines provide an evidence-based, patient-centered framework to optimize cardiovascular and renal outcomes in patients with diabetes, promoting early intervention, individualized therapy, and comprehensive risk reduction.
