Findings in rat hearts should not change practice; leaves open mitochondrial-independent mechanisms of ischaemic recovery.
Does pretreatment with propranolol or reserpine improve mechanical and ultrastructural recovery in isolated working rat hearts subjected to normothermic ischaemic arrest?
Beta-blockade and catecholamine depletion improve mechanical and ultrastructural recovery of ischaemic rat hearts without improving mitochondrial function, suggesting mitochondrial failure is not the primary cause of irreversible ischaemic damage.
