Stenting Versus Bypass: Matching the Procedure to the Patient

No. A pectoralis muscle spasm is aggravated by a localized range-of-motion test, reaching an arm behind the back, for example, while true angina is unaffected by arm or shoulder movement. The two are mechanistically unrelated: manage the muscle spasm with non-steroidal anti-inflammatory drugs and treat a genuine coronary spasm as coronary disease.

If a frozen elephant trunk has not been done, the alternative is EVAR, endovascular aortic repair, sealing off the re-entry tear with a stent graft placed through the groin. In the thoracic aorta this is straightforward because there are no major branch vessels to route around. In the abdominal aorta, where the gastroepiploic, superior mesenteric, renal and inferior mesenteric arteries branch off, patient-specific imaging has to be sent to a stent graft manufacturer so they can build a graft with branches positioned at the right levels before it is deployed.

Complexity is determined by the workup, not by symptoms alone. Watch the troponin and creatine kinase trend: if enzymes keep rising, or symptoms have not improved after 72 to 96 hours of conservative therapy, antiplatelet medication, or thrombolysis where that pathway was used, that is the signal to make a specialist referral so a senior physician can perform an angiogram and determine disease severity directly.

One ECG showing borderline bradycardia, combined with a two-year history that has defeated standard testing, points toward right coronary artery disease, which is notoriously difficult to pick up outside direct angiography. Pending access to a coronary angiogram, start dual antiplatelet therapy, 75 mg of clopidogrel and 150 mg of aspirin daily, plus a statin at 40 mg daily to stabilize the plaque, and check cardiac enzymes at his next chest pain episode. A positive enzyme without an ECG change would classify him as unstable angina, since that diagnosis only requires a troponin derangement alongside chest pain, not an ECG change. A strong maternal family history of cardiac illness is relevant here even though he is young and does not smoke or drink.

RFCL is an old scoring system we do not use anymore; it produces more false negatives than anything useful. Score this patient with a EuroSCORE now, and a SYNTAX score once an angiogram is available.

More than ten years of reliable stent performance remains rare, while a well-performed coronary artery bypass graft typically offers disease-free survival in excess of ten years, often fifteen to twenty.

A patient with more than ten years of life expectancy ahead of them should generally receive a bypass rather than a stent, since a stent's limited lifespan makes a second intervention likely later.

Severe comorbidity, advanced age, frailty, reduced life expectancy, restricted mobility, a SYNTAX score below 22, and anatomy where complete surgical revascularization is unlikely to succeed, such as poor-quality graft conduits.

Diabetes, reduced ejection fraction, left main coronary disease, complex multivessel disease with a high SYNTAX score, and any pathology involving the ascending aorta.
