A 58-year-old man presents to the outpatient clinic with a 3-month history of reproducible substernal chest pressure. The pain occurs consistently after walking three blocks and resolves completely within 5 minutes of resting. He has a medical history of hypertension, type 2 diabetes mellitus, and hyperlipidemia. His current medications include lisinopril, metformin, and atorvastatin. Vital signs are within normal limits, and physical examination is unremarkable. Arrange the following interventions in the most appropriate chronological sequence for the evaluation and management of this patient's condition.
- 1Obtain a resting 12-lead electrocardiogram
- 2Perform a noninvasive functional stress test
- 3Perform invasive coronary angiography
- 4Proceed with percutaneous coronary intervention
- 5Enroll in a supervised cardiac rehabilitation program
Answer
The correct sequence begins with a resting 12-lead ECG, followed by a noninvasive stress test, invasive coronary angiography, percutaneous coronary intervention, and finally, cardiac rehabilitation.
The evaluation of stable ischemic heart disease (SIHD) follows a strict logical progression designed to minimize patient risk while accurately diagnosing and treating ischemia. A resting 12-lead ECG is universally the first step to identify baseline abnormalities. If the resting ECG is normal, a noninvasive functional stress test is utilized to provoke and document ischemia. Only patients who demonstrate high-risk features on stress testing proceed to invasive coronary angiography to map the anatomy. If a severe, amenable lesion is identified, percutaneous coronary intervention (PCI) is performed. Finally, post-revascularization care must include enrollment in cardiac rehabilitation to ensure optimal secondary prevention and recovery.
Step-by-Step Solution
Key Concept
The stepwise evaluation and management of Stable Ischemic Heart Disease progressively advances from noninvasive diagnostic testing to invasive diagnostics, targeted therapy, and long-term rehabilitation.
