Questions and Answers

In the context of ACS and dissection management, what is the most critical differentiating factor between aortic dissection and acute coronary syndrome (ACS) when managing a hypertensive emergency?

The choice of antihypertensive medication, where beta-blockers (e.g., labetalol) are favored in aortic dissection to reduce aortic wall stress, while nitrates might be used cautiously or avoided. (correct)
The specific antihypertensive agent used; labetalol is preferred in ACS while nitroprusside is the first line in aortic dissection to rapidly lower blood pressure.
The patient's age, with ACS being more common in younger individuals and aortic dissection in the elderly.
The choice of antihypertensive medication, where beta-blockers are preferred in both conditions to reduce heart rate and blood pressure.

What key historical and examination findings would most strongly suggest a musculoskeletal source of chest pain over acute coronary syndrome (ACS)?

Constant, dull chest pain unaffected by movement or palpation, accompanied by a persistent cough and fever.
Pain radiating to the left arm, associated with diaphoresis and exertional onset, relieved by rest.
A crushing chest pain associated with nausea, vomiting, and a feeling of impending doom.
Sharp, localized pain exacerbated by deep inspiration or palpation, with a history of recent strenuous activity or trauma. (correct)

What is the most appropriate approach to managing a patient presenting with chest pain but a normal initial troponin level, in order to balance patient safety and resource utilization?

Employ a risk stratification tool (e.g., HEART score) and engage in shared decision-making, providing clear safety netting instructions and follow-up. (correct)
Discharge the patient with reassurance, as a normal troponin rules out acute coronary syndrome.
Admit the patient for continuous cardiac monitoring and serial troponin measurements, regardless of other clinical findings.
Prescribe a course of empiric antibiotics to cover potential atypical pneumonia, a common cause of chest pain.

An elderly patient presents with sudden-onset, severe chest and abdominal pain. A pulse deficit is noted in the lower extremities. What is the most critical diagnosis to consider?

Aortic dissection, given the combination of sudden pain, pulse deficit, and symptoms above and below the diaphragm. (C) Signup and view all the answers

When documenting the assessment of a patient with non-emergent chest pain, what specific negative findings are most important to explicitly record to support a non-cardiac diagnosis?

Absence of exertional pain, diaphoresis, radiation, and vomiting to reduce the likelihood of acute coronary syndrome. (D) Signup and view all the answers

Which historical factor most significantly increases the likelihood of misdiagnosing Acute Coronary Syndrome (ACS) in urgent care settings?

A 45-year-old patient presents with chest pain and exertional dyspnea. After initial assessment, you're considering Pulmonary Embolism (PE). According to established guidelines, what is the appropriate next step following the application of the Wells score/clinical gestalt?

Flashcards

Non-Emergency Chest Pain Causes

Conditions that are not immediately life-threatening, mimicking chest pain symptoms.

Aortic Dissection Characteristics

Sudden, severe chest pain that may also present with symptoms above and below the diaphragm.

Muscular Chest Pain

Reproducible pain on palpation or movement, and absence of serious symptoms like exertional pain or diaphoresis.
