In a patient with left chest pain radiating to the jaw, lightheadedness, and a history of smoking, what should be the next step in management?

• A. Exercise stress test
• B. ECG
• C. Cardiac catheterization
• D. Start antiplatelet therapy

Answer: (B)

In a scenario where a patient presents with chest pain radiating to the jaw, lightheadedness, and a significant history of smoking, it is essential to first assess the patient's cardiac function. An electrocardiogram (ECG) is the most appropriate next step in management in this situation because it helps in the immediate evaluation of the heart's electrical activity and can identify signs of ischemia, infarction, or arrhythmias.

Given the patient's symptoms and risk factors for cardiovascular disease, an ECG can provide vital information that will influence further management decisions. For instance, abnormalities such as ST-segment changes can suggest acute coronary syndrome, necessitating urgent interventions. Therefore, obtaining an ECG is crucial in promptly diagnosing any immediate cardiac issues and directing subsequent management effectively.

Other options like an exercise stress test, cardiac catheterization, or starting antiplatelet therapy are not the appropriate initial steps without first determining the current cardiac status through ECG. An exercise stress test would typically be reserved for stable patients who are not currently experiencing acute symptoms. Cardiac catheterization is an invasive procedure generally considered after initial evaluation suggests significant coronary artery disease. Starting antiplatelet therapy might be appropriate if acute coronary syndrome is suspected, but again, it comes after initial
