Role of ACE inhibitors in patients with diabetes mellitus

Area of Science:

• Cardiology
• Nephrology
• Endocrinology

Background:

• Diabetes mellitus, particularly type 2, is an epidemic with serious micro- and macrovascular complications.
• Early recognition and treatment of diabetes complications can slow or halt their progression, with potential for reversal of tissue damage.
• While glycemic control is vital, managing blood pressure and lipid levels are also critical therapeutic strategies.

Purpose of the Study:

• To highlight the significant role of cardiovascular drugs, specifically ACE inhibitors, in managing diabetes mellitus complications.
• To review the evidence supporting the organ-protective effects of ACE inhibitors in diabetic patients.
• To advocate for the early introduction of ACE inhibitors in the treatment of diabetes mellitus.

Main Methods:

• Review of experimental and epidemiological data on the renin-angiotensin-aldosterone system in diabetes.
• Analysis of studies comparing ACE inhibitors with other antihypertensive agents regarding organ protection.
• Evaluation of the impact of ACE inhibitors on kidney, heart, eye, and peripheral nerve function in diabetic patients.

Main Results:

• Activation of the renin-angiotensin-aldosterone system contributes to vascular complications in diabetes.
• ACE inhibitors provide organ protection beyond blood pressure reduction, preserving kidney, heart, and neurological function.
• Favorable effects are attributed to the inhibition of angiotensin II's hemodynamic and tissue effects.

Conclusions:

• ACE inhibitors play a pre-eminent role in managing diabetes mellitus complications due to their antihypertensive and organ-protective properties.
• These agents offer superior protection for organs like the kidney and heart compared to other antihypertensives at similar blood pressure control.
• There is a strong, growing rationale for the early use of ACE inhibitors in patients with diabetes mellitus.
