The small molecule pifithrin-μ reversibility inhibits the mitochondrial pathway of apoptosis. The neuronal effects of pifithrin-μ applied after cardiac arrest are unknown. We hypothesized that pifithrin-μ reduces neuronal damage in the most vulnerable brain region, the hippocampus, after cardiac arrest. ⋯ Temporarily inhibition of apoptosis with pifithrin-μ after cardiac arrest decreases the number of injured neurons in the CA1 segment of hippocampus in a cardiac arrest rat model, without clinical correlate. Further studies should elucidate the role of this neuroprotective agent in different settings and with longer cardiac arrest.
