Encouraging results have been reported for doxycycline (MMP inhibitor) in reducing adverse LV remodeling in ST-segment elevation myocardial infarction (STEMI) patients (Tetracycline (Doxycycline) and Post Myocardial Infarction Remodeling TIPTOP trial) [105] and for metformin (AMPK activator) in reducing left ventricular mass indexed to height in non-diabetic patients with coronary artery disease (MET-REMODEL trial) [108]. The gene discussed is PRKAA1; the disease is myocardial infarction.
