1
Q

Dysthymic Disorder

A

A chronic depression of mood which does not meet the criteria for major depression, in terms of either severity or duration of individual episodes, yet the patient still has loss of interest, lack of appetite or pleasure, and low energy

2
Q

When a patient presents with multiple unrelated physical symptoms, what diagnosis needs to be considered?

A

Depression

3
Q

How do antidepressant agents work?

A
  1. Enhance neurotransmitter release
  2. Reduce neurotransmitter breakdown
  3. Inhibit the reuptake of the neurotransmitter by the presynaptic neuron
4
Q

Persons with depression have a greater chance of developing or dying from…

A

Cardiovascular disease (even after controlling traditional risk factors such as smoking, blood pressure, and lipid levels)

5
Q

Women, especially those younger than age __, attempt suicide more frequently than men, but men are __ likely to complete suicide.

A

30

more

6
Q

Why do all antidepressants carry an FDA “black box” warning?

A

Because they increase the risk of suicidal thoughts and behaviors especially in the first months of treatment (patients should be treated for at least 6-9 months during their first episode of major dpression)

7
Q

Fluoxetine (Prozac)

Paroxetine (Paxil)

Sertraline (Zoloft)

Fluvoxamine (Luvox)

Citalopram (Celexa)

Escitalopram (Lexapro)

A

SSRIs (increase the amount of serotonin by blocking the presynaptic neuron’s ability to reuptake serotonin)

Considered first-line agents for the treatment of depression because they have a low toxicity

Side effects: sexual dysfunction, weight gain, GI disturbance, fatigue, and agitation

8
Q

Venlafaxine (Effexor)

Duloxetine (Cymbalta)

Mirtazapine (Remeron)

Desvenlafaxine (Pristiq)

A

SNRIs (affect both the serotonergic and noradrenergic systems)

9
Q

Amitriptyline (Elavil)

Nortriptyline (Pamelor)

Desipramine (Norpramin)

Clomipramine (Anafranil)

Doxepin (Sinequan)

10
Q

Phenelzine (Nardil)

Tranylcypromine (Parnate)

Selegiline (Eldepryl)

A

MAOIs (caused increased amounts of serotonin and NE to be released during nerve stimulation)

Q

Bupropion (Wellbutrin)

Amoxapine (Asendin)

Trazodone (Desyrel)

A

Atypical Agents (act similarly to SSRIs, TCAs, and MAOIs)

A

< 100 pg/mL

> 500 pg/mL

28
Q

One of the earliest chest x-ray findings in CHF is…

A

cephalization of the pulmonary vasculature

29

A

New York Heart Association (NYHA): I-IV

American Heart Association (AHA): A-D

31
Q

When acute pulmonary edema caused by CHF is diagnosed, the next step in management is…

A

the administration of a loop diuretic

*Furosemide is generally the treatment of choice, both for its potent diuretic effect and for its rapid bronchial vasculature vasodilation

32
Q

Benefits of nitroglycerin for a patient with CHF

A

When given IV, it reduces oxygen demand by reducing preload and afterload

Rapidly reduces blood pressure (treatment of choice when a CHF patient has an elevated BP; used with caution in a hypotensive patient)

33
Q

Benefits of morphine in a patient with CHF

A

Analgesic + Anxiolytic

Also a venodilator (primary effect) and arterial dilator, resulting in a reduction in preload and an increase in cardiac output

34
Q

What should the daily salt intake be for a CHF patient?

A

2-4 g/d

*A normal American diet contains 6-10 g/d

35
Q

First-line therapy in patients with CHF and reduced LV function

A

ACE inhibitors

*ARBs can be used in place of ACE inhibitors in a patient who does not tolerate an ACE inhibitors because of side effects (e.g., cough)

36
Q

When are ACE inhibitors contraindicated?

A

Pregnancy

Hypotension

Hyperkalemia

Bilateral renal artery stenosis

37
Q

When should β-blockers be used in the setting of CHF

A

Can reduce sympathetic tone and the cardiac muscle remodeling associated with chronic heart failure

Reduce mortality in patients with an EF < 35% and are primarily indicated in patients with NYHA Class II or III heart failure, or in patients with coronary artery disease

*Administration in high doses, in the setting of acute CHF, can worsen symptoms

38
Q

Loop vs Thiazide Diuretics in the setting of CHF

A

Loop (furosemide, bumetanide, torsemide, ethancrynic acid): used in all stages of CHF

Thiazide (HCTZ, chlorthalidone): used in mild heart failure and may be used in combination with others

39
Q

Calcium channel blockers, in general, are ______ in systolic heart failure

A

contraindicated because they increase mortality

Exception = amlodipine

*Nondihydropyridine calcium channel blockers (diltiazem, verapamil) are useful in HF caused by diastolic dysfunction, as they promote increased CO by lowering HR, which allows for more ventricular filling time

40
Q

Cardiac Resynchronization Therapy

A

Shown to reduce mortality and hospitilization in patients with symptomatic CHF in spite of maximal medical therapy

Beneficial for patients with NHYA Class III or IV HF and reduced EF with ECG evidence of abnormal ventricular conduction (i.e., prolonged QRS duration)

A

At least 6

46
Q

The hallmark PE finding in hypertrophic cardiomyopathy (HCM) is?

A
  1. A systolic murmur that decreases in intensity with the athlete in the supine position (increased ventricular filling, decreased obstruction)
  2. Increases with the Valsalva maneuver (decreased ventricular filling, increased obstruction)

*outflow murmurs increase in intensity upon lying down

47
Q

Sexually active, symptomatic, and high risk females should be screen for gonorrhea and Chlamydia by…

A

urine nucleic acid amplification

48
Q
