Cardiac Medications and their effects
Question | Answer |
---|---|
Nitrates (nitroglycerin) | Decrease proload through peripheral vasodilation, reduce myocardial oxygen demand, reduce angina, may also dilate coronary arteries, improve coronary blood flow. |
Beta-adrenergic agents (Propranolol) | Reduce myocardial oxygen demand by reducing HR and contractility; control arrhythmias, chest pain, reduce BP |
Calcium channel blockers (Cardizem, Procardia) | Decrease HR, decrease contractility, dilate coronary arteries, reduce BP, chest pain, control arrhythmias |
Antiarrhythmias (four main drugs, ex: Quinidine, Procainamide) | Alter conductivity, restore normal heart rhythm, control arrhythmias, improve CO |
Antihypertensives (four main class, ex: Propranolol) | Control HTN, maintain DBP < 90 mmHg, decrease afterload, reduce myocardial oxygen demand |
Digitalis | Decrease HR, Increase contractility, Main treatment in CHF |
Diuretics (ex: Lasix) | Decrease proload and afterload, control HTN |
Aspirin | May prevent MI |
