Key result
Long-term propranolol treatment in rats post-myocardial infarction completely abolished the oxidative stress increase and reduced cardiac sensitivity to catecholamine-induced arrhythmias.

Does long-term propranolol treatment improve LV remodeling and oxidative stress in a rat model of chronic heart failure?
In a rat model of post-MI heart failure, long-term propranolol prevents oxidative stress and catecholamine-induced arrhythmias without altering compensatory hypertrophy.

Hypothesis-generating for propranolol's antiarrhythmic effects via oxidative stress reduction in rat post-MI HF; leaves open human translation.
Mansuy et al. (2000) conducted an RCT in Myocardial infarction and chronic heart failure. Propranolol vs. No treatment (infarcted controls) and sham-operated rats was evaluated on Progression of left ventricular dysfunction, remodeling, and oxidative stress. Long-term propranolol treatment in rats post-myocardial infarction completely abolished the oxidative stress increase and reduced cardiac sensitivity to catecholamine-induced arrhythmias.
