219
Diagnostic evaluation of suspected DVT
In summary: Doppler US and/or plasma D-dimer initial tests >> if inconclusive, contrast venography >> follow-up with testing for inherited or acquired thrombophilias
- duplex (Doppler) US is the best initial test when the probability of DVT is intermediate-high for it has good sensitivity and specificity in symptomatic patients. A negative test in an individual with intermediate to high probability of a DVT requires further testing
- plasma D-dimer enzyme-linked immunoassay (ELISA) will be elevated in 95-98% of DVTs. Therefore, most useful in ruling OUT DVT since a negative test makes DVT unlikely). In contrast, positive results are supportive but not diagnostic because it could be an number of other causes
- contrast venography , which is best used when clinical findings suggestive of DVT are not confirmed on the initial US
- test for other inherited or acquired anticoagulation deficiencies (Protein C, protein S, antithrombin, prothrombin gene mutation, antiphospholipid antibodies, factor V Leiden)
220
Diagnostic evaluation of suspected PE (5)

Define "coronary heart disease"
atherosclerotic changes to the coronary vasculature. this causes decreased blood flow through the coronary arteries due to partial obstruction or vasospasm
atherosclerosis develops with the formation of fatty streaks, fibrous plaques, and complicated lesions that narrow the lumen of the coronary arteries
248
What is "angina pectoris"
myocardial ischemia secondary to inability of the coronary arteries to supply oxygenated blood to meet the myocardial oxygen demands
249
What is "acute coronary syndrome"
when an atherosclerotic plaque ruptures, may cause thrombus formation that impedes or completely occludes the coronary lumen
2 types: unstable angina, acute myocardial infarction
250
(2) types of acute coronary syndrome
- acute MI
| - unstable angina
251
leading cause of death for women in the US
coronary heart disease
252
Symptoms of chronic stable angina pectoris
clinical syndrome characterized by discomfort in the chest, jaw, shoulder, back, or arm that is precipitated by exertion and relieved by rest or nitroglycerin
stable angina has predictable frequency, severity, duration, and provocation -- exercise
this pattern remains the same, unless there is an acceleration of the disease progress
253
Symptoms of acute coronary syndromes
- chest pain described as pressure, heaviness, squeezing, crushing, aching
- pain typically involves the sternum and/or epigastrum
- pain may radiate to the shoulder, arm, jaw, neck, or back
- may be associated with nausea, vomiting, diaphoresis, or dyspnea
254
Diagnostic evaluation of coronary heart disease
In summary: ECG and consider labs (troponins, myoglobin) >> Stress tests (exercise/treadmill, medication, nuclear) >> coronary angiography
- ECG = changes will depend on the location of vessel(s) involved, amount of myocardium involved, and the duration of ischemia. ST-segment depression and symmetric T wave inversion in affected leads may occur during an acute episode of chronic stable angina. ACS may demonstrate ST segment elevation
- stress tests (exercise, pharmacologic, or nuclear) = will demonstrate ischemic changes or angina during the test. myocardial perfusion imaging aka nuclear stress test is used to confirm and assess extent and location of coronary artery disease
- coronary angiography is the definitive test for coronary artery disease (uses dye and CT/radiographs)
- lab tests involving myocardial markers = may include troponin I and T (high sensitivity and specificity, become elevated within 3-4 hours of an event and remain elevated for as long as 7-14 days after an event), and myoglobin (not as specific as troponins, released within 1-3 hours of myocardial cell injury and normalizes in 24 hours)
255
Management of acute coronary syndromes
requires revascularization procedures which may include:
- percutaneous transluminal coronary angioplasty (PTCA) via the femoral artery
- coronary artery bypass graft (CABG)
256
Medication classes for angina/CHD
- aspirin 81-325 mg/day inhibits platelet aggregation, primary prevention
- sublingual nitroglycerin 0.4mg PRN for symptomatic relief of anginal episodes
- beta blocks are the preferred initial therapy, decrease myocardial demand by decreasing HR, systolic BP, and contractility
- calcium channel blockers (long-acting) promote peripheral arterial vasodilation thereby reducing oxygen demand by decreasing afterload, and they also decrease coronary vasospasm
- long-acting nitrates (isosorbide dinitrate, nitropaste, nitropatches) cause venous dilation, which decreases venous return to the heart and leads to modest arterial vasodilation resulting in decreased myocardial oxygen demand
- make sure to treatment comorbid HTN, diabetes, dyslipidemia, and tobacco use
257
What is allergic rhinitis
inflammation of the mucous membranes of the nose in response to contact with certain allergies, triggering the production of immunoglobulin E (IgE) antibodies >> histamine release >> subsequent edema, itching, discharge, and sneezing

affects 10-20% of adults and typically onsets between ages 10-20yo
258

- skin tests to determine specific allergens are the gold standard for diagnosis
- serum allergy tests can be considered, including radioallergosorbent test (RAST) which measures amount of specific IgE to individual allergens correlating with the allergic sensitivity to that substance .... can be used to determine specific IgE to a number of different allergens at one time, but is expensive and not as sensitive as skin tesitng
263

non pharm:
- allergen avoidance (especially the bedroom)
- vaccuum, dusting, remove carpeting, feather pillows, and stuffed animals
- reduce exposure to pets
- air conditioning and air filters
pharm classes:
- antihistamines (first line) >> good for itching, sneezing, rhinorrhea (with minimal effect on congestion)
- decongestants >> can be used alone or in combination of antihistamines, best for nasal congestion specifically
- topical nasal corticosteroids >> increasingly becoming first line given their effectiveness, however, they have a slow onset of action and are maximally effective if used as a maintenance therapy
- mast cell stabilizers/intranasal cromolyns >> effective for prophylaxis, not acute, as they have no direct anti-inflammatory or antihistamine effects
- montelukast (leukotriene receptor antagonist) >> reduces inflammation
264
First line medication for allergic rhinitis
antihistamines
and, increasingly, intranasal corticosteroids given their effectiveness
