Implication

Supports local vascular CE effects in rat hypertension models; leaves open translation to human therapy.

Key Points

To assess the role of the local vascular wall renin-angiotensin system in blood pressure regulation and evaluate how converting enzyme inhibitors affect local vessel wall function independently of plasma enzymes.
Reviewed mechanisms of vascular converting enzyme activity, local angiotensin II production, and downstream functional changes within arterial and venous tissues.
Analyzed blood pressure responses alongside tissue and plasma converting enzyme recovery dynamics following oral converting enzyme inhibitor withdrawal in spontaneously hypertensive rats.
Converting enzyme inhibitors suppress local vascular converting enzyme and reduce tissue angiotensin II levels while promoting the accumulation of vasodilator peptides and prostaglandins.
Following drug withdrawal in spontaneously hypertensive rats, the slow recovery of converting enzyme activity in the vasculature mirrored the delayed rise of blood pressure, contrasting with rapid plasma enzyme recovery.

Population

Spontaneously hypertensive rats and general discussion on cardiovascular disorders (hypertension, congestive heart failure)

Intervention

Orally administered converting enzyme (CE) inhibitors

Outcome

Effects on the local vascular tissue renin-angiotensin system and blood pressure controlsurrogate

This review highlights the importance of the local vascular renin-angiotensin system and suggests that its inhibition by CE inhibitors plays a key role in their therapeutic efficacy for hypertension and heart failure.
