Why the study?

Does the reversal of hypertension normalize structural and compositional changes in the thoracic aorta of male and female rats?

Population

Male and female rats

Comparison

Hypertension for 10 weeks followed by its reversal vs Normotensive controls

Design

Preclinical

Follow-up

10 weeks (hypertension phase)

Authors

HWHarvey WolinskyAlbert Einstein College of Medicine

Discussion

Member takes

Implication

May incompletely reverse aortic remodeling after BP normalization in males; leaves open sex-specific adjunctive strategies.

Structured PICO

Does the reversal of hypertension normalize structural and compositional changes in the thoracic aorta of male and female rats?

P
Population
Male and female rats
I
Intervention
Hypertension for 10 weeks followed by its reversal
C
Comparator
Normotensive controls
O
Outcome
Structural and compositional changes in the thoracic aorta wall (diameter, wall thickness, tangential tension, wall stress, medial area, elastin, collagen, and noncollagenous proteins)surrogate

Hypertension induces partially irreversible structural and compositional changes in the thoracic aorta of rats, with notable sex differences upon blood pressure normalization, suggesting limitations to the benefits of blood pressure reduction alone.
