study guide #4 Flashcards
list the common causes of non-cardiac chest pain
- peptic ulcer disease -PPI & abt
- gastroesophogeal reflex disease -give trial dose of PPI for 1-2 mos
- CAD- EKG & check for lipids
- costochondritis -heat, NSAIDs reassurance self limiting, avoid over use, take NSAIDs with food. F/U rtc if symptoms worsen
- acute anxiety
- MS pain
life threaten cardiac chest pain
**Aortic Dissection: tear in aorta- sudden tear pain located in ant. or post. may radiate to arms/leg/ back, may have hypotension
**pulmonary embolism: able to localize painful area over lung s/x dyspnea apprehension, hemoptysis gripping or stabbing pain that is mod-severe and may increase with deep breaths, may radiate to neck or shoulder, crackles over site
risk factor: bed rest, orthopedic surgery
explain life span considerations in determining the dx when pt. has chest pain
after cardiac & life threatening non-cardiac conditions are excluded, the pt’s age is often the most important factor in determining the dx.
- -> younger pts chest pain generally caused by more benign underlying conditions
- ->older pts with more risk factors and comorbid conditions are more likely to have serious causes of their chest pains
- ->regardless of age cardiac & life threatening noncardiac complications should be rule out first
- *under 40 : normal EKG sufficient to r/o cardiac chest pain
- *older than 40 or risk factors : cardiac enzyme, stress test, coronary angiography may be necessary
- *risk smoking, DM, obesity stress hyperlipidemia
- *women: ECG stress test is less reliable as dx, more invasive image based stress tests are more accurate
discuss risk factors for coronary artery disease
male >45 y.o female >55 family hx of premature coronary heart disease cigarette smoking hypertension low HDL 130
when should the patient with chest pain be sent to ED ?
NON-LOCALIZED pain
lasting >20 minutes
associated with diaphoresis dyspnea n/v dizziness radiation to neck jaw shoulder or arm
life threatening condition : MI
- -> sudden onset not relieved by rest or nitro
- ->associated symptoms
life threatening condition: Aortic dissection
- -> sudden tearing pain located in the anterior or posterior chest
- -> may radiate to arm, legs, abd, or back
life threatening condition PE
- -> able to point to area over the lung
- ->dyspnea
- -> apprehension
- -> hemoptysis
- -> gripping or stabbing pain of moderate or severe intensity that may increase with deep breathing
- -> may radiate to neck or shoulder
- ->bed rest and orthopedic surgery are risk factors
- -> women older adults and DM pts may present with atypical symptoms
how might a pt. describe angina?
demonstrates characteristic symptoms that occur with predictable frequency severity duration and provocation
the symptoms occur with exertion, are relieved by rest or no more than one nitro tablet and generally last for 1-3 minutes.
angina
often occurs with nausea, fatigue, SOB, sweating. may be stable or unstable. stable goes away unstable stays >30 minutes. stable is usually with exertion but unable may be with rest and different from usual pattern
classic angina
Classic: the chest pain & discomfort common with angina may be described as pressure, squeezing fullness or pain in the center of your chest. some people with angina symptoms describe angina as feeling like a vise is squeezing their chest or feeling like heavy weight has been placed on their chest
woman experience angina
different from classic symptom
nausea SOB abdominal pain or extreme fatigue, with or w/o chest pain.
may feel discomfort in the neck jaw or back or STABBING PAIN instead of the more typical chest pressure.
this lead to delays tx*
- Describe the physical examination findings when your patient has sustained an MI. (Remember that about 90% of the diagnosis of an acute coronary event is made from the patient’s history
Sx: sudden onset of non-localized pressure/pain, constrictive (not a sharp stabbing pain), not relieved with nitro, associated sx (cool, pale, moist skin)
MI -General appearance
-grimacing, diaphoresis, cyanosis, pallor, tachypnea
MI - VS
B/P may be elevated in MI
MI - Heart sounds
- -Auscultate
- a new transient, paradoxical S2 during pain can indicate coronary ischemia
- S4 (atrial gallop) indicates stressed heart which can result from MI hypertension or CAD
- irregular heart rhythms are often heard during
MI-Examine Extremities
- peripheral cyanosis can indicate hypoxia
- lower extremity edema may indicate CHF
Which is more predictive of an acute MI – EKG with ST elevations or history and presenting symptoms?
- The history and presenting symptoms is the short answer. A normal ECG can rule out MI in patients below 40. However, this is not the case in older patients (pg 435). If a patient presents with a hx and physical exam consistent with MI and has a normal ECG, further testing is definitely indicated (as noted in previous response). Essentially, the history and physical trumps the ECG
- A normal ECG in a patient younger than 40 yo is generally sufficient to rule out a cardiac problem. What will patients older than this and/or with risk factors require in terms of diagnostic testing? Will this vary with gender?
Cardiac Workup:
- Cardiac troponins (I&T): Rise within 2-4 hrs post MI and remain elevated 7-10 days
- Serum cardiac enzymes (CPK): Rise 4-8 hrs after MI and return to normal 48-72 hours
- SGOT and LDH: elevated later and not indicators of acute MI
- Elevated leukocytes, ESR: non specific indicators
- EKG: does not completely rule out, but decreases odds by 70-90%
- ECG
- Labs- CKMB, troponins, myoglobin
- Stress Test
- Echocardiogram
- Testing will vary with gender. False positive results in women more likely occur with many of the cardiac tests and speculation suggests it’s because of women’s lower hematocrit level and higher circulating estrogen level.
- Stress echocardiography may prove a more accurate method of noninvasice CAD testing in women
Pulmonary embolus
dyspnea, hemoptysis, sharp pain
- decreased breath sounds - orthopedic surgery is a risk factor
PE
What diagnostic tests are needed? Give your rationale.
-according to a discussion posting you would refer to the hospital STAT and they would run tests
Costochondritis-
inflammation of the rib cartilage. Pain with palpation over cartilage between ribs and sternum
Costochondritis H & P , management
• often is history of recent
o illness with coughing
o strenuous exercise
• precipitating and relieving factors - usually pain affected by movement or inspiration
• sometimes trauma, strain, or relation to emotional stress
• any other joints involved
- application of heat and NSAIDs*
- Condition is self-limiting, avoid overuse and trauma, take NSAIDs with food
- Return if condition worsens or no improvement
peptic ulcer disease
- episodic gnawing or burning epigastric pain
- pain occurring 2-5 hours after meal or on empty stomach
- nocturnal pain relieved by food, antacids, or antisecretory agents
- it is usually related to meals
