Key result
Rabbits with chronic heart failure had a significantly higher incidence of ventricular fibrillation during acute myocardial ischemia compared to controls (76% vs 27%, P<0.01).
Why the study?
Does chronic heart failure increase the susceptibility to ischemia and reperfusion-induced arrhythmias in a rabbit model?
Does chronic heart failure increase the susceptibility to ischemia and reperfusion-induced arrhythmias in a rabbit model?
Absolute Event Rate: 76% vs 27%
p-value: p=<0.01
Rabbits with chronic heart failure exhibit enhanced susceptibility to ischemia and reperfusion-induced arrhythmias, potentially driven by delayed repolarization.

Hypothesis-generating for VF risk in failing hearts during ischemia-reperfusion; leaves clinical translation open pending human data.
Bril et al. (1991) studied Chronic heart failure. Chronic heart failure vs. Control group was evaluated on Incidence of ventricular fibrillation during the first 20 min postcoronary artery ligation (p=<0.01). Rabbits with chronic heart failure had a significantly higher incidence of ventricular fibrillation during acute myocardial ischemia compared to controls (76% vs 27%, P<0.01).
