Comparative Study
Ivabradine but not propranolol delays the time to onset of ischaemia-induced ventricular fibrillation by preserving myocardial metabolic energy status.
Heart rate reduction (HRR) has shown a beneficial impact on the prevention of ventricular fibrillation, which could be explained by increased myocardial blood flow and preservation of mitochondrial structure. Here, we assessed the HRR impact on time to onset of ventricular fibrillation (TOVF) and myocardial metabolic energy status. ⋯ Unlike PROPRA, IVA delayed the time to onset of ischaemia-induced ventricular fibrillation by preserving myocardial energy status, supporting the pertinence of IVA in the management of patients with coronary artery disease.
