Chest pain

Physicians will typically keep asking a patient about chest pain even after they have identified it as pressure. Emergency Room Physicians need to consider whether pain is esophageal acid reflux [burning], musculoskeletal pain[stabbing or with movemment] or cardiac pain [at rest or exertional], the latter requiring a 'chest pain protocol' evaluating cardiac enzymes creatine kinase and toponin and ending with a stress test or cardiac catheterization in the hospital. It may help for the evaluator to write out 'chest pain' or 'chest pressure'[feeling of ‘heaviness of chest’]and refer back to this to expedite the interview. Associated symptoms are pain in the neck, jaws, shoulders, arms or hands; breathlessness [dyspnea], inappropriate sweating, nausea, or exertional dizziness or physical exhaustion. It is important to memorize this list so that you can say you have reviewed a complete set with the patient. Diabetes reduces or obliterates symptoms of myocardial ischaemia and infarction because of autonomic neuropathy. Associated physical signs of an impending heart attack [angina, ischemia] or heart attack [myocardial infarction] are high or low blood pressure,increased pulse rate[tachycardia) and respiratory rate[tachypnoea]. Dyspnea and/or Pain on inspiration [pleurisy] should be evaluated by computed tomography for pulmonary embolus, another fatal treatable process.

Medication/allergies

Assessment

ROS

syncope, exercise intolerance, PND/orthopnea, angina, CVA

Impression

Is the chest pain typical or atypical for angina?
- look at the ECG, cardiac enzymes, CXR

Differential Diagnosis

CV: stable or unstable angina (< 10 min, worsened by cold air, stress)
IHD (> 30 min, unrelieved)
aortic dissection
pericarditis (hrs to days, relieved by sitting up and leaning forward)

RESP: pneumothorax, PE, pleuritis
GI: GERD, PUD, esophageal spasm
MSK: costochondritis, rib fracture
MISC: panic attack, herpes zoster

Plan

Canadian Cardiovascular Society (CCS) Classification

Angina only with strenuous, rapid or prolonged activity
Angina only slightly limiting ordinary activity, such as walking up-hill, climbing stairs rapidly, or climbing more than 2 blocks on the level, at a normal pace.
Angina with level walking at normal pace for less than 1-2 blocks, or less than 1 flight of stairs
Inability to carry on any physical activity without developing angina
