What does this research mean for the field?

Ischemia-related ventricular arrhythmias are driven by specific cellular electrophysiologic abnormalities (abnormal automaticity, triggered activity, or re-entry), and therapeutic interventions should be tailored to the underlying ionic mechanism, such as using calcium antagonists for triggered activity or sodium-channel blockers for re-entry with a long excitable gap.

Implication

May guide mechanism-based antiarrhythmic selection in ischemia; leaves open prospective outcome trials before practice change.

Structured PICO

Population

Patients with ischemia-related ventricular arrhythmias in the acute, subacute, and chronic phases of myocardial infarction

Intervention

Antiarrhythmic therapies targeted at specific electrophysiologic mechanisms (calcium antagonists, potassium-channel openers, magnesium, class III antiarrhythmics, sodium-channel blockers)

The review provides a mechanistic framework for understanding ischemia-related ventricular arrhythmias and tailoring antiarrhythmic drug therapy based on the underlying cellular electrophysiologic abnormalities.
