Uses Flashcards
Beta Blockers
Angina: decrease contractility and HR = decreased heart work
Help reestablish supply and demand ratio
Hypertension: decreases cardiac output by decreasing contractility and HR and blood flow
Prevents MI: decrease cardiac work
Migraines, long QT, cardiomyopathy
Nitrates
Prevent angina
Prophylactic – protective/ preventative
Used before events the patient knows will cause angina
How?
Vasodilation – decreased venous return – decreased EDV – decreased contractility – decreased heart rate – decreased heart work
Calcium Channel Blockers
Angina Prinzmetal = unstable angina/ coronary artery spasm Caused by Beta blockers Hypertension Decreased resistance – decreased BP
Digitalis
Heart failure
Most frequently prescribed for heart failure with atrial arrhythmias
Moving more Ca2+ into the cell results in less available for pacer cells – decrease conduction velocity
Diuretics
Hypertension
Congestive heart failure
Peripheral edema
ACE Inhibitors
Hypertension
Heart failure: especially congestive
Will also decrease afterload for pumping
ARBs
Hypertension
Heart failure: especially congestive
Will also decrease afterload for pumping
Direct Acting Vasodilators
Hypertension
Class IA
Tachyarrhythmia: SVT and V-tach
Re-entry tachyarrhythmia
Class IB
Digitalis toxicity, ventricular tachycardia but not SVT
Class IC
Atrial fibrillation
SVTs
Class II
Tachyarrhythmia
Class III
Primarily SVT
Class IV
SVT and PSVT
Statins
Decrease lipid (cholesterol) – only thing it is officially prescribed for Shown to improve endothelial function
Bile Acid Sequestirns
Binds to bile acid so they cannot be utilized therefore the liver converts more cholesterol into bile
Decrease blood lipid profile
Niacin
Decrease free fatty acid release therefore decrease triglyceride therefore decrease VLDL and in long term decrease LDL
Increase lipoprotein lipase, increase HDL, decrease Lp(a)
Fibrates
Decrease triglyceride, change VLDL to LDL, increase LPL
Anti-thrombotic/ Anti-platelets/ fibrinolysis/ plasminogen activators
Coronary artery disease Previous MI Pro – clotting condition • Prosthesis • A – fib • Valve replacement • Stents
Hyperglycemia
High blood sugar
Bronchodilators
COPD
Treat bronchospasms from Beta Blockers
