Differential Diagnosis of Chest Pain Lecture Powerpoint Flashcards
fucking a
Why is the differential so large for chest pain?
Because many of the afferent nerves (especially the vagal) are from the same source and thus can cause very diffuse symptoms
Sharp chest pain or tearing or ripping is likely to be…..
Aortic dissection, PE, pneumothorax, or peridcarditis rather than cardiac in origin
Abrupt onset vs gradual worsening of angina or acute coronary syndrome
These generally tend to be gradually worsening opposed to abrupt and sudden onset
Does cardiac differential pain get better or worse with eating?
Generally does not impact
If a patient has had a _____ or ____ (tests) recently that were negative, then we can rule out cardiac disease of differential. However with ___ test, cannot.
Cardiac catheterization, coronary CT angiogram, stress test
Mediastinitis risk factors (4)
- Recent cardiac surgeries
- Esophageal perforation
- trauma
- descending infection from head or neck
Acute coronary syndrome risk factors (4)
- smoking
- obesity
- male sex
- cocaine abuse
Acute aortic dissection risk factors (4)
- marfan syndrome

- SCUBA diving
Pulmonary embolus risk factors (4)

- trauma
- cancer
Pericardial tamponade risk factors (4)
- malignancy

- blunt or penetrating injury
S1Q3T3
Classic finding for right heart strain characteristic of pulmonary embolism,
Electrical alternans
Classic finding for cardiac tamponade
Cardiac troponin I and T test
A cardiac ischemia marker that is seen to be elevated when measured in multiple sessions within 3 hours, peaking at 12 hours, and remain elevated 7-10 days indicating ischemia has occurred
D-dimer test
Nonspecific marker for clot formation, often used to detect DVT and potential PE in a patient but could be due to any clotting in the body
