Why the study?
Definitive evidence for the cardioprotective role of TRPV1 channels and the function of sensory neuropeptides CGRP and SP after cardiac injury is lacking.
Does TRPV1 gene knockout or blockade impair postischemic recovery in isolated perfused mouse hearts?
Population
Isolated perfused hearts from TRPV1-null mutant and wild-type mice
Comparison
TRPV1 gene knockout and/or pharmacological agents versus wild-type or untreated hearts
Design
Preclinical Langendorff perfused heart study
Follow-up
30 minutes of reperfusion

TRPV1 supports postischemic recovery in isolated mouse hearts; leaves open whether agonism could mitigate human ischemia/reperfusion injury.
Does TRPV1 gene knockout or blockade impair postischemic recovery in isolated perfused mouse hearts?
TRPV1 gene deletion or blockade impairs cardiac recovery after ischemia/reperfusion injury, indicating a cardioprotective role for TRPV1 possibly mediated via substance P release.
