Why the study?

Does experimental heart failure induced by coronary artery ligation reduce vascular density in peripheral skeletal muscle in New Zealand White rabbits?

Population

22 New Zealand White rabbits (experimental model of CHF)

Comparison

Congestive heart failure induced by coronary… vs Sham surgery without coronary artery ligation

Design

Preclinical

Follow-up

up to 21 days

Implication

May link skeletal muscle rarefaction to exercise intolerance in experimental CHF; leaves open relevance to patients.

Structured PICO

Does experimental heart failure induced by coronary artery ligation reduce vascular density in peripheral skeletal muscle in New Zealand White rabbits?

P
Population
22 New Zealand White rabbits (experimental model of CHF)
I
Intervention
Congestive heart failure induced by coronary artery ligation
C
Comparator
Sham surgery without coronary artery ligation
O
Outcome
Vascular density in peripheral skeletal muscle (tibialis anterior muscle)surrogate

Experimental heart failure leads to vascular rarefaction and endothelial apoptosis in peripheral skeletal muscle, providing a potential mechanism for exercise intolerance in CHF.
