Cardiac Medications and their effects

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the 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
