Q

What are good questions to ask a Pt who presents with CP?

A
  • Are you currently having chest pain?
  • What were you doing when it started?
  • What seems to bring the pain on?
  • Have you had pain like this before?
  • How long did it last, what made it go away?
  • Is it worse with activity?
  • Have you ever had a heart exam/workup before?
  • Have you taken an aspirin today?

Q

When asking what were you doing when the pain started and what seems to bring the pain on, you are assessing what?

A

Whether the pain is brought on by exertion. If the pain was brought on by exertion and went away with rest this shows stable angina while if the pain came on suddenly while the Pt was relaxing is much more concerning for an unstable condition.

Q

If CP is relieved after taking sublingual nitro that means it is definitely a cardiac cause right?

A

Nope! Nitro causes smooth muscle relaxation, meaning heart muscle will relax but so will esophageal muscle, so it does not help with diagnostic eval.

A
  • Belching, bad tatse in mouth, dysphagia
    • Esophageal disease
  • Vomiting
    • MI or GI problems
  • Diaphoresis
    • Is a concerning sign regardless of what is going on.
    • MI more likely than an esophageal disease
  • Syncope
    • Dissection, PE, critical AS, ruptured AAA
  • Near-syncope
    • Myocardial ischemia
  • Fatigue
    • May be presenting symptom of MI, especially in the elderly.

41
Q

A diaphoretic Pt with CP is?

A

A bad omen, likely cardiac in origin.

42
Q

If a Pt states that their CP radiates to their arms is this a strong predictor of an acute MI?

A

Yes

43
Q

A Pt states their CP radiates to the area between their scapulae, what should you consider?

A

Aortic dissection

44
Q

A large area of chest pain (think Pt gestures to their entire chest) is concerning for what?

A

Ischemic etiology of pain.

45
Q

If a Pt can take one finger and point to their exact area of pain is this more or less concerning than someone with diffuse chest pain?

A

Less concerning, less likely to be due to an ischemic cause.

46
Q

Is the severity of pain a good predictor of the presence of CAD?

A

No

47
Q

Acute onset of CP with the greatest intensity at the beggining should make you think?

A

PTX, dissection, or PE

48
Q

Gradual onset of CP that increases over time should make you think?

A

Ischemic cardiac pain

49
Q

CP with a crescendo pattern (coming and going) is often caused by?

A

Esophageal disease

50
Q

If CP last for seconds or is constant over the course of weeks is it likely an ischemic etiology?

A

No, ischemic pain usually lasts several minutes.

51
Q

If CP has a circadian rhythm (morning worse than afternoon) is it likely due to ischemia?

A

Yep, this is due to increased sympathetic tone in the morning.

52
Q

True or False: Heart attacks are more likely to occur in the morning just after waking up than in the afternoon?

A

True

53
Q

Which histories are likely to be contributory to the frequency of CP?

A
  • CV History
    • If Pt has a history of previous MI they are more likely to have another.
  • GI History
    • Pts who have had biliary colic in the past but still have a GB are likely to experience biliary colic again
  • Family History
    • If a Pt has a strong family history of cardiac disease they are much more likely to experience cardiac problems.
54
Q

If a Pt has had a previous MI and comes in complaining that their current chest pain feels the same or worse as when they had their last MI, they are?

A

Having an MI until proven otherwise. Get them to the ED.

55
Q

Risk factors for CP?

A
  • Tobacco use
  • Family Hx
  • DM/HTN/Lipids
  • Cocaine (unlikely to be the cause of ACS)
  • Previous history of DVT/PE (increases risk for future VTEs)
  • Marfans/Pregnancy (Increase risk for aortic dissection)
  • ETOH
  • NSAIDs
  • Age????
56
Q

Is age a risk factor for cardiac causes of CP?

A

Yes and no. While the risk of cardiac causes for CP increase with age, younger and younger people are presenting with MIs. Do not assume because a Pt is young that they can’t be having an MI.

57
Q

Does a lack of risk factors for cardiac disease rule out a cardiac cause for a Pts CP?

A

Nope

58
Q

What exam findings point to ACS?

A
  • New S3 or S4
  • Systolic BP <80 mm/Hg
    • Hypotensive MI is much worse than hypertensive MI, Hypertension means there is adequate perfusion, hypotension means bad perfusion and death.
  • Crackles on auscultation
    • Bad prognosis

Remember the absence of these does not mean ACS isn’t present.

59
Q

A likelihood ratio of greater than 1 indicates?

A

The test result is associated with the disease.

60
Q

A likelihood ratio of less than 1 indicates?

A

The test result is associated with the absence of the disease.

61
Q

If the likelihood ratio (LR) is 2, 5, or 10 it increases the probability the Pt has the disease by what percent?

A
  • LR=2 increases the probability Pt has the disease by 15%
  • LR=5 increases the probability Pt has the disease by 30%
  • LR=10 increases the probability Pt has the disease by 45%
62
Q

A likelihood ratio of what is considered highly significant?

A

LR>10

63
Q

Which symptom of CP has the highest likelihood ratio (LR) of being caused by an MI?

A
  • CP that radiates to both arms (LR=9.7) indicates there is about a 50/50 chance they are having an MI.
    • In contrast, CP that radiates to the left arm (LR=2.2) has about 15% chance of MI or the right shoulder (LR=2.9) about 20% chance of MI.
  • Not sure if we need to know specific LRs but Jaynstein seems to like them.
63
Q

What features decrease the likelihood of a MI?

A
  • Pleuritic pain (LR=0.2)
  • Sharp or Stabbing pain (LR=0.3)
  • Positional pain (LR=0.3)
  • Reproducible pain (LR=0.4)

LR less than 1 are associated with the disease not being present.

64
Q

Symptoms indicating a high likelihood of ACS?

A
  • CP radiating to one or both arms
  • CP associated with exertion, nausea, vomiting, or diaphoresis
  • CP described as pressure or as “worse than pervious angina or similar to previous MI”.
65
Q

Symptoms indicating a low likelihood of ACS?

A
  • Stabbing, pleuritic, or positional CP
  • Pain in an inframammary location
  • Pain not associated with exertion
  • Pain reproducible with palpation
66
Q

The Marburg Heart Score does what?

A

It helps to rule out CAD in CP Pts. It has a high negative predictive value (rule out CAD) but a low positive predictive value (Rule in CAD).

67
Q

What are the criteria of the Marburg Heart score, each is worth 1 point (max points: 5) (She said in the PPT we don’t need to memorize this)

A
  • Women >64 years, Men >54 years
  • Known CAD, CVD or PAD
  • Pain worse with exercise
  • Pain not reproducible with palpation
  • Patient assumes pain is cardiac
68
Q

A Marburg Heart Score of 2 or less indicates what?

A

98% of Pts with a score of 2 or less will NOT have CAD

69
Q

Is a Pt with a Marburg Heart Score (MHS) of 5 more likely to have CAD than a Pt with a score of 3?

A

Not necessarily, the MHS has a low positive predictive value meaning it is not good for predicting the likely hood of having CAD, rather it is useful in predicting the likelihood of not having CAD. Only 23% of Pts with an MHS score of 3 or more have CAD; while 98% of Pts with an MHS score of 2 or less do not have CAD.

70
Q

What are the acute MI criteria when looking at an ECG?

A

ST-elevation >2mm in continuous leads

71
Q

What are the ischemia criteria when looking at an ECG?

A
  • Large Q wave >2mm in inferior leads
  • ST-Depression in continuous leads
  • T-wave inversion in continuous leads
72
Q

You get an in-office ECG that has concerning findings, what do you do next?

A

Send to ED for further eval

73
Q

Your in-office ECG is non-diagnostic but you are still suspicious that the Pts CP may be from CAD what needs to be done?

A

Further testing with cardiac biomarkers (troponin) to evaluate from NSTEMI, get them to the ED for this.

74
Q

Your ECG comes back normal in a CP Pt who you don’t suspect has CAD. When might you consider getting a chest radiograph?

A

If they have CP and evidence of respiratory disease *cough, dyspnea, Hx of pulmonary disease).

75
Q

Should a troponin be done as an outpatient?

A

No right or wrong answer depends on the provider. In general probably best to send to the ED for the test.

76
Q

What are the guidelines for ordering an outpatient troponin?

A

None exist but should meet the standard of care of the ED.

If CP has been resolved completely for greater than 3 hours and a troponin comes back negative you are done with the workup they are not having an MI.

If chest pain has not been completely resolved for more than three hours when the troponin is drawn, will need to get a second one an hour after the first was drawn. If these standards cannot be met in the outpatient setting, don’t draw a troponin outpatient.

77
Q

So when is it reasonable to draw a troponin outpatient?

A

Straight from the slides: “It is reasonable to use a single troponin test in general practice to exclude the possibility of acute myocardial infarction (AMI) in asymptomatic patients whose symptoms resolved at least 12 hours prior, so long as they have no high-risk features and a normal electrocardiogram.”

78
Q

What does HEART stand for when obtaining the HEART score?

A
  • History
  • ECG
  • Age
  • Risk Factors
  • Troponin

Remember a HEART score can only be done in an EM setting when a trop can be obtained.

79
Q

Jaynstein’s final thoughts on CP?

A
  • Nitro response is not diagnostic
  • Post-prandial pain may be ischemic
  • Discomfort thresholds vary
  • Patient histrionics may influence you
  • “atypical” is typical of something
  • Value of the careful history and physical
