In medicine, myocardial revascularization is "the restoration of blood supply to the myocardium."[1]

Revascularization procedures include:

Clinical practice guidelines address management and selection of patients.[5]

Elective percutaneous transluminal coronary angioplasty is not clearly better to optimal medical therapy.[6]

Coronary artery bypass is more effective for myocardial revascularization of coronary heart disease than percutaneous transluminal coronary angioplasty[7], especially for patients with diabetes who have stenosis of twocoronary arteries.[8][8][9] Coronary artery bypass is also more effective than percutaneous transluminal coronary angioplasty with drug-eluting stents; however, bypass may increase the rate of stroke.[8][10]

Clinical practice guidelines suggest that the SYNTAX score may help determine choice of procedure for myocardial revascularization.[11]

  • "Calculation of the Society of Thoracic Surgeons (STS) and SYNTAX scores is reasonable in patients with unprotected left main and complex CAD."[5]
  • However, the more recent FREEDOM trial found the SYNTAX score did not predict benefit.[8]

Appropriateness of decisions for PTCA

Less than half of patients with stable angina who receive PTCA are receiving optimal medical therapy.[12]

Of patients without indications for myocardial revascularization, cardiologists will recommended percutaneous transluminal coronary angioplasty for 21% of patients.[13] A second study found that 12% of elective percutaneous transluminal coronary angioplasties were done for inappropriate reasons.[14]

Regarding drug eluting stents, about 50% of patients received them for off-label purposes.[15][16] Patients receiving stents for off-label indications have more adverse outcomes.[15][16]
