Role of physiological ischemia training in suppressing ventricular remodeling and ventricular arrhythmia in patients after myocardial infarction: a randomized controlled trial.

Objectives: The randomized controlled study explored whether physiological ischemia training (PIT) can inhibit ventricular remodeling and reduce ventricular arrhythmias in the early period of acute myocardial infarction (AMI).

Methods: AMI patients with hypotension or bradycardia were randomly divided into PIT (n = 21) and control (n = 20) groups. Meanwhile, patients with normal blood pressure (BP) and heart rate (HR) were randomly divided into PIT+angiotensin-converting enzyme inhibitor (ACEI) and/or β-blocker (AB) (n = 30) and AB (n = 30) groups.
