Chest Pain in a 58-Year-Old With Atypical Features
A 58-year-old man presents to urgent care with 90 minutes of substernal pressure that began while mowing his lawn and now radiates to the left jaw. He rates it 5/10, denies diaphoresis, and says it eased somewhat with rest but returned when he walked to the exam room. Past history: type 2 diabetes for 11 years, hypertension, 30 pack-year smoking history. Vitals: BP 148/92, HR 96, RR 20, SpO2 96% on room air, temp 37.0 C. The clinic has 12-lead ECG, troponin point-of-care testing, aspirin, and nitroglycerin, but no beds and a 25-minute ambulance transfer to a PCI-capable hospital. He asks whether he can just drive himself home and follow up Monday.
1. How should the NP risk-stratify this presentation, and what features make it high versus low concern?

This is a high-risk presentation despite the absence of diaphoresis and a moderate 5/10 rating. Exertional onset relieved by rest, radiation to the jaw, and recurrence on minimal exertion constitute typical anginal features. Diabetes, hypertension, and a 30 pack-year smoking history substantially raise pretest probability of coronary disease; diabetes can blunt classic autonomic symptoms, so absence of sweating is not reassuring. The NP should not anchor on atypical intensity. Instead, treat this as possible acute coronary syndrome and act within minutes: obtain a 12-lead ECG and interpret it for ST elevation, ST depression, or T-wave changes, place the patient on continuous monitoring, establish IV access, and give aspirin 162-325 mg chewed unless contraindicated. Point-of-care troponin supports but does not exclude ACS, especially early after symptom onset. The key judgment is that a normal single troponin and a nondiagnostic ECG do not permit discharge in a patient with ongoing exertional symptoms and this risk profile.
2. What disposition and transfer decisions should the NP make, given the clinic's limited resources?

The NP should activate emergency medical services for transfer to the PCI-capable hospital rather than allow self-transport. Reasons: ongoing or recurrent chest pain carries risk of arrhythmia or arrest during transit; EMS can provide monitoring, defibrillation, and prehospital ECG transmission; and a 25-minute ambulance ride can be shortened in practice with lights and sirens. The patient should be told plainly that driving himself is unsafe and that this is not a routine follow-up issue. Before transfer, the NP should give aspirin, consider nitroglycerin if blood pressure permits and there is no right ventricular infarct or recent phosphodiesterase inhibitor use, and avoid delaying transport for serial troponins. Documentation should include symptom timeline, ECG interpretation, medications given, and the explicit conversation about refusing self-transport if he objects. If he lacks capacity to consent or refuses, the NP should follow clinic policy and emergency transfer provisions.
3. How should the NP explain the plan to a patient who wants to go home?
Read the worked answer
Use plain language and a clear recommendation. Example: 'Your symptoms and history put you at real risk for a heart attack, even though your ECG and blood test may look okay right now. Those tests can be normal early on. I want you to go by ambulance to the hospital where they can do a definitive evaluation and, if needed, open a blocked artery quickly. Driving yourself could be dangerous if you develop chest pain or a rhythm problem on the road.' Acknowledge his preference and autonomy, but state the recommendation firmly and document the discussion. Offer to call a family member, address transportation concerns, and clarify that this is a precaution based on risk, not a confirmed diagnosis. Avoid overpromising that 'it is probably nothing' and avoid minimizing his fear; explain that the ambulance is the safest way to get the same evaluation faster.
