Angioplasty versus coronary artery bypass selection
When is angioplasty preferred over bypass surgery?
Angioplasty (stent) is usually preferred when disease is focal and suitable for a catheter fix, and when a quicker recovery is important. Bypass is favored when disease is complex, widespread, or involves key branches. General guide (discussed in Heart Team conferences): - Angioplasty: 1–2 vessels; discrete blockages; right coronary or circumflex lesions; acute heart attack to quickly open the artery; high surgical risk or frailty; prior bypass with a new focal blockage; when symptoms persist despite medicines and anatomy is stent‑friendly. - Bypass surgery: Left main disease (especially complex), 3‑vessel disease—particularly with diabetes, reduced heart function, or extensive calcification; diffuse/long lesions, multiple tight blockages, or poor stent landing zones; when durable long‑term relief is prioritized; failed prior stents with restenosis; associated valve/aortic disease needing surgery. Key points: both improve symptoms; survival advantage is clearer with bypass in left main or multivessel disease with diabetes. Before any stent for stable symptoms, ensure objective ischemia (stress imaging) or invasive physiology (FFR/iFR), and optimize medical therapy. In an emergency heart attack, angioplasty is the immediate treatment to save heart muscle. This is educational information, not medical advice.
