Implication

Supports non-BP mechanisms of vascular hyperplasia in this rat model; leaves open relevance to human renal hypertension.

Structured PICO

Do antihypertensive treatments (reserpine or captopril) or correction of renal ischaemia prevent or reverse vascular smooth muscle cell hyperplasia in rats with renal hypertension?

P
Population
Rat model of renal hypertension
I
Intervention
Reserpine, captopril, or correction of renal ischaemia
C
Comparator
Untreated renal hypertension
O
Outcome
Vascular wall changes (smooth muscle cell hyperplasia and connective tissue deposition)surrogate

In a rat model of renal hypertension, blood pressure reduction with captopril does not prevent vascular smooth muscle hyperplasia, suggesting blood pressure is not the sole determinant of vascular wall remodeling.
