From the Guidelines
For a 61-year-old obese male with left-sided chest pain, immediate risk stratification should include a thorough evaluation using validated tools like the HEART score or TIMI risk score, as recommended by the most recent guidelines 1.
Initial Evaluation
Begin with a detailed history focusing on pain characteristics (onset, duration, radiation, exacerbating/relieving factors), cardiovascular risk factors, and previous cardiac events. Perform a physical examination including vital signs, heart and lung auscultation, and assessment for signs of heart failure.
Diagnostic Testing
Order an immediate 12-lead ECG to evaluate for ST-segment changes or arrhythmias, and cardiac biomarkers (troponin, preferably high-sensitivity) at presentation and 3-6 hours later, as suggested by the 2014 AHA/ACC guideline 1. Additional testing should include basic metabolic panel, complete blood count, and chest X-ray.
Risk Stratification
If initial evaluation suggests intermediate to high risk, proceed with stress testing (exercise or pharmacological) or coronary CT angiography based on the patient's ability to exercise, as recommended by the 2020 ACR Appropriateness Criteria 1. For patients with positive biomarkers, concerning ECG changes, or high-risk features, consider immediate cardiology consultation and possible cardiac catheterization.
Considerations
This comprehensive approach is essential because obesity significantly increases cardiovascular risk, and at 61 years of age, this patient has multiple potential etiologies for chest pain ranging from acute coronary syndrome to non-cardiac causes that require systematic evaluation to ensure appropriate management. The use of risk scores, such as the HEART score, can aid in prognosis and management, as stated in the 2014 AHA/ACC guideline 1.
From the Research
Risk Stratification of 61-year-old Obese Male Patient Complaining of Left Side Chest Pain
- The patient's symptoms and presentation should be evaluated using a combination of history, physical examination, electrocardiogram (ECG), and cardiac biomarkers, such as troponin levels 2, 3, 4.
- The ECG should be performed immediately, within 10 minutes of presentation, to distinguish between ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS) 2, 3, 4.
- If the ECG shows ST-segment elevation, the patient should be diagnosed with STEMI and rapid reperfusion with primary percutaneous coronary intervention (PCI) should be performed within 120 minutes of first medical contact 3, 4.
- If the ECG does not show ST-segment elevation, troponin levels should be measured to evaluate for non-STEMI (NSTEMI) 2, 3.
- The patient's risk should be stratified using a risk calculator, such as the Thrombosis in Myocardial Infarction (TIMI) or HEART score, to determine the need for further evaluation and treatment 2.
- Patient-reported symptoms, such as sweating and shoulder pain, can improve the prediction of acute coronary syndrome (ACS) diagnosis when combined with ECG and troponin results 5.
- The patient's obesity and age should be considered as risk factors for ACS, and the patient should be evaluated and managed accordingly 2, 3, 6.
Diagnostic Evaluation
- The diagnostic evaluation should include:
Management
- The management of the patient should include:
- Aspirin therapy, if not contraindicated, as soon as possible 6
- Nitroglycerin to relieve angina, if not contraindicated 6
- Beta blockers, if not contraindicated 6
- Rapid reperfusion with primary PCI, if STEMI is diagnosed, within 120 minutes of first medical contact 3, 4
- Fibrinolytic therapy, if PCI is not available, for patients with STEMI 3, 4
