Term
Bile Acid Binding Resins
Definition
Response: decrease LDL, increase TG and HDL
Term
Statins
Definition
Response: Decrease LDL and TG, increase HDL
Term
Cholesterol Absorption Blockers
Definition
Response: Decrease LDL and TGs, Increase HDL
Term
Niacin (Nicotinic Acid)
Definition
Response: Decrease LDL, TGs and VDLD, Increase HDL
Term
Fibrates
Definition

Response: Decrease LDL and TG, increase HDL

Increase HDL-C b/c of PPARalpha stim of apoA-I and apoA-II expression

Term
Nitrates
Definition

Response: DECREASE SYSTEMIC VENOUS CONTRACTION (decrease work, decrease O2 needed,

Decrease filling P, decrease preload),

Decrease systemic arterial contraction (decrease work, decrease O2 needed, decrease filling pressure, decrease afterload), 

Decrease pulmonary/systemic edema (decrease work),

Decrease large coronary artery contraction (increase O2 supply)

Term
B-adrenergic Blockers
Definition

Response: decrease HR and contractility, arterial blood pressure (decrease O2 demand), increase coronary flow via increase time in diastole (increase O2 supply)

HT: decrease CO, renin release and SNS to decrease BP (not sure how or why but it does)

Term
Ca Channel Blockers
Definition

Response: DV: decrease HR and contractility (decrease O2 demand),

All: decrease systemic arterial contraction (decrease O2 demand) and coronary artery contraction (increase O2 supply)

Term
Ranolazine
Definition
Response: No affect on BP or HR, increase exercise tolerance, decrease anginal attacks
Term
Aspirin
Definition
Response: PHENOMENAL decrease in risk of death or MI, can see benefits in 1st day of treat!
Term
ADP Inhibitors
Definition
Response: decrease risk of death or MI, early is better
Term
GP IIb/IIIa Receptor Inhibitor
Definition
Response: Decrease in risk of death or MI, early is better
Term
Heparin
Definition
Response: LMWH > Heparin @ reducing death or MI in combo w/aspirin in unstable angina
Term
Fondaparinux
Definition
Response: reduce death or MI in ACS (acute coronary syndromes like acute myocardial ischemia) similar to heparins
Term
Direct Thrombin Inhib
Definition
Response: stable levels of x-coag (not yet proven beneficial in unstable angina)
Term
Fibrinolytic (TPA)
Definition
Response: recanalize (re-allow flow) thrombotic occlusion, restore coronary flow, reduce infarct size, improve myocardial function and survival over short and long terms
Term
Analgesics
Definition
Response: decrease pain, anxiety, restlessness, ANS, venous and arterial contraction (all decrease O2 demand)
Term
Renin Angiotensin Inhib
Definition
Response: decrease venous and arterial contraction, SNS, and ventricular remodeling (for 2nd prevention), TPR (HT), increase renal Na/H2O excretion
Term
Oral X-Coags
Definition
Response: decrease growth of existing thrombi, prevent new thrombi formation
Term
Loop Diuretics
Definition
Response: increase renal excretion of Na, H2O, K, Ca, Mg, CI and H, relax systemic veins (increase venous capacitance): both cause decrease preload (decreased energy needs), diuretic effect causes decrease in edema (decrease in dyspnea, like in congestive heart failure)
Term
Thiazide Diuretics
Definition
Response: increase renal excretion of Na, H2O, K+, Mg++, Cl- and H+ BUT decrease Ca excretion.  Diuretic effect causes decrease in edema (decrease in dyspnea) and proload (decrease E need).  Lower efficacy than loop diuretics, activation of renin-angiotensin-aldosterone system (limits use in hypertension)
Term
K+ Sparing Diuretics
Definition
Response: increase Na, H2O excretion, decrease Ca, K, Mg and H excretion.  Low efficacy alone.
Term
Aldosterone Antagonists
Definition

Response: increase excretion of Na, H20, Cl, decrease excretion of Ca, K, Mg and H.  Low efficacy alone.  Inhibit ventricular remodeling (slows progression of disease b/c aldosterone stimulate mineralocorticoid in heart and promote fibrous lay down)

HT: monotherapy as eplerone

Term
Renin Angiotensin Inhibitors (HF) 
Definition
Response: decrease venous and arterial contraction, VENTRICULAR REMODELING, SNS, preload and afterload, increase excretion of Na and H2O
Term
Direct Arterial Vasodilators
Definition
Response: decrease arteriolar contraction -> decrease afterload -> decrease O2 demand (work)
Term
Digoxin
Definition
Response: decrease SNS, filling pressure, edema, AV conduction, increase CO, PNS, exercise tolerance and PR (b/c slower conduction @ AV node)
Term
B agonists
Definition
Response: Increase CO, decrease filling P
Term
Phosphodiesterase Inhibs
Definition
Response: increase contractility, rate of relax, CO, decrease venous and arterial contraction (DILATE ARTERIOLES), filling pressure and pulmonary arterial contraction
Term
Nesiritide
Definition
Response: decrease venous (STRONG) and arterial contraction, and filling pressure, increase CO
Term
Class IA
Definition
Response: decrease conduction and automaticity (b/c Na block), increase refractoriness (b/c K block), QRS (slower conduction, b/c Na channel block) and QT (increased refractoriness b/c K channel block)
Term
Class IB
Definition
Response: decrease conduction, automaticity (only in abnormal, not in normal) and QT (NOT BIG CHANGE IN EKG)
Term
Class IC
Definition
Response: decrease CONDUCTION, automaticity, increase QRS (VERY marked)
Term
Class II
Definition
Response: decrease conduction, automaticity (normal and abnormal), increase PR (delay @ AV node)
Term
Class III
Definition
Response: increase refractoriness, QT (*), decrease automaticity and PR (minor)
Term
Class IV
Definition
Response: Decrease AV conduction, and automaticity, increase PR (delay @ AV node)
Term
Adenosine
Definition
Response: Decrease AV conduction and sinus node rate, increase PR (longer conduction @ AV node)
Term
Aliskiren
Definition

Response: decrease angiotensin II actions, venous and arterial contraction, SNS, TPR

Increase renal Na/H2O excretion
