Amiodarone is effective for treating which arrhythmias?
Answer: Both atrial and ventricular arrhythmias
Amiodarone is a broad-spectrum antiarrhythmic (Class III) effective for both atrial arrhythmias (AF, flutter) and ventricular arrhythmias (VT, VF).
Which drug class is used to reduce heart rate in atrial fibrillation through AV nodal blockade?
Answer: Beta-blockers and non-dihydropyridine calcium channel blockers
Beta-blockers and non-dihydropyridine calcium channel blockers (diltiazem, verapamil) slow AV nodal conduction to achieve ventricular rate control in atrial fibrillation.
Aspirin and a P2Y12 inhibitor (dual antiplatelet therapy) are required after coronary stent placement for:
Answer: At least 6–12 months (drug-eluting stent) to prevent stent thrombosis
Dual antiplatelet therapy (DAPT) is mandatory for at least 6–12 months after drug-eluting stent placement to prevent stent thrombosis during endothelialization.
Dobutamine stress echocardiography uses dobutamine to:
Answer: Increase heart rate and contractility to simulate exercise stress
Dobutamine is a beta-1 agonist that increases heart rate and contractility, simulating exercise-like physiologic stress to assess wall motion and viability.
Protamine sulfate is used to reverse the effects of:
Answer: Unfractionated heparin
Protamine sulfate binds and neutralizes unfractionated heparin; it only partially reverses LMWH and has no effect on DOACs.
Statins are prescribed after acute coronary syndrome primarily to:
Answer: Reduce LDL cholesterol and stabilize atherosclerotic plaques
High-intensity statin therapy after ACS reduces LDL, stabilizes vulnerable plaques, and has proven mortality benefits independent of baseline cholesterol levels.
