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]

Coronary artery bypass is more effective for myocardial revascularization of coronary heart disease than percutaneous transluminal coronary angioplasty[6], especially for patients with diabetes who have stenosis of three coronary arteries.[7][8] Coronary artery bypass is also more effective than percutaneous transluminal coronary angioplasty with drug-eluting stents; however, bypass may increase the rate of stroke.[9]

The SYNTAX score may help determine choice of procedure for myocardial revascularization.[10]

"Calculation of the Society of Thoracic Surgeons (STS) and SYNTAX scores is reasonable in patients with unprotected left main and complex CAD."[5]

Appropriateness of decisions for PTCA

Less than half of patients with stable angina who receive PTCA are receiving optimal medical therapy.[11]

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

Regarding drug eluting stents, about 50% of patients received them for off-label purposes.[14][15] Patients receiving stents for off-label indications have more adverse outcomes.[14][15]
