    -Weight Loss->specify a target weight

    -Sodium restrictions

    -Alcohol reduction

    3 mechanisms to lower blood

    pressure

    1. lower heart rate

    2. Decrease stroke volume

    3. Decrease peripheral vascular resistance

    The Kidney

    -Renin released from renal juxtaglomerular celss activates RAA

    system

    -regulation of blood volume

    -when blood pressure rises for any reason, the kidney should ideally

    secrete more sodium... which will lower blood volume

    -lowering blood volume tends to decrease cardiac output and

    restore pressure toward normal

    Sympathetic Nervous system

    major role in regulating CO and TPR

    **elevated sympathetic nervous system activity may result in

    transient or sustained HTN

    Diuretics

    -used to get rid of excess water.

    -lower blood pressure by decreasing CO

    -Very effective as anti-HTN with AA's

    -Depression

    -Impotence

    -Nightmares

    Cardioselective Beta Blockers

    -greater affinity for beta-1 receptors(heart), less likely to

    bronchospasm

    -less vasoconstriction

    -less interference with insulin therapy

    Alpha-Beta BlockersProvide benefits of beta blockade with additional benefit of

    vasodilation by blocking apha-1 recpetors

    Beta Blockers with ISA-reduce resting heart rate and CO less than traditional beta blockers

    -NOT to be used in CAD and MI patients

    Lipid Solubility

    How readily the drug crosses the blood-brain-barrier-Incidence of CNS side effects may be exacerbated with higher lipid

    solubility

    **Beta blockers should not be stopped abruptyl...There is a

    withdrawal syndrome and they should be weaned off!

    Calcium Channel Blockers(CCB's)

    Block intracellular entry of calcium in cardiac and vascular tissue in

    particular

    -this action leads to arteriolar smooth muscle relatxation and

    decrease TPR

    -Well tolerated

    -contraindicated in CHF with exception of amlodopine

    -ideal in elderly with increased TPR

    -used in CAD/Angina in patients that are unable to use beta

    blockers(asthma/COPD)

    thrombin

    the most powerful clotting factor in the clotting cascade. combines c

    fibrinogen to form fibrin.

    Low Molecular Weight Heparin

    Lovenox. this medication binds to antithrombin II and the

    preferential effect is on Factor Xa. is not very good at inhibiting

    thrombin formation. sub Q route only. less risk involved, but 5x more

    expensive.

    D-dimer a diagnostic study for clots. this will tes for a fragment of fibrin.

    Unfractioned Heparin (UFH)

    Tx and prevention of thromboembolism. dependent on the ability to

    bind and catalyze antithrombin III....this anticoagulant neutralizes

    the activities of several clotting factors. Inactivates thrombin and Xa.

    this halts growth and propogation of thrombi.

    Protamine Sulfate the antidote for someone with blood that is too thin.

    Warfarin

    inhibits factors II, VII, IX, X, protein C and S. used to prevent

    recurrent thromboembolic events. highly protein bound, has a

    narrow therapeutic range. desired anticoag. effect achieved in 3-4

    days. oral use only.

    Vitamin K the antidote for warfarin

    International normalized ratio

    a more consistant measure of coagulation. normal range is 0.75-

    1.25, but therapeutic range is 2-3 for most depending on their

    condition.

    Aspirinan antiplatelet medication. this medication is used to prevent platelet

    aggregation, there is no interruption of the clotting cascade.

    Glycoprotein IIb/IIIa Inhibitor

    this is a potent antiplatelet agent. produces antithrombotic effect by

    direct inhibition of the binding of fibrinogen to the glycoprotein IIb/IIIa

    receptor.

    Bile acid resins

    a hyperlipidemiapharmacological tx that binds bile salts in exchange

    for chloride ions in the intestines. bile-acid drug complex prevents

    reabsorption of bile acids; liver then increases the production of bile

    acid, which is able to increase the uptake of LDLs....thereby

    decreasing the circulating LDL. lowers the LDL by 15-2030%,

    increases HDL by 3-5%, and no change/increase in TG. SE:

    1) ECG; 2) CXR; 3) echo What 3 tests help make diagnosis of mitral stenosis?

    1) LA enlargement; 2) RV

    hypertrophy; 3) +/- afibName 3 findings of ECG consistent with mitral stenosis:

    1) double-density right heart border;

    2) posterior displacement of

    esophagus; 3) elevated left

    What findings on CXR suggest left atrial enlargement?

    decrease preload: 1) diuretics; 2)

    sodium restrictionGoals of medical treatment of mitral stenosis

    What is the effect of chronic mitral regurgitation on preload?

    decreased afterload as a portion of

    stroke volume is ejected retrograde
