Cardiovascular drugs that can cause digoxin toxicity
A number of cardiovascular drugs predispose patients to digoxin toxicity, including verapamil, quinidine, and amiodarone. The dosage of digoxin must be reduced if given concomitantly with these drugs. The presumed mechanism underlying this interaction involves the ability of these drugs to inhibit the P-glycoprotein transporter.
Mnemonic: These drugs cause you to go whack! VAQ - Verapamil, Amiodarone, Quinidine
Other drugs to keep in mind are Diltiazem, Spironolactone, Flecainide.

SYNTAX score mnemonic
In the SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) trial, patients with 3-vessel and left main coronary artery disease (LMCAD) treated with coronary artery bypass graft surgery (CABG) compared with percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) had lower 5-year rates of death, myocardial infarction (MI), stroke, or unplanned revascularization.
