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

Revascularization procedures include:

Coronary artery bypass is more effective for myocardial revascularization of coronary heart disease than percutaneous transluminal coronary angioplasty[5], especially for patients with diabetes who have stenosis of three coronary arteries.[6] Coronary artery bypass is also more effective than percutaneous transluminal coronary angioplasty with drug-eluting stents; however, bypass may increase the rate of stroke.[7] The SYNTAX score may help determine choice of procedure for myocardial revascularization.[8]

Of patients without indications for myocardial revascularization, cardiologists will recommended percutaneous transluminal coronary angioplasty for 21% of patients.[9] A second study found that 12% of elective percutaneous transluminal coronary angioplasties were done for inappropriate reasons.[10]

Regarding drug eluting stents, about 50% of patients received them for off-label purposes.[11][12] Patients receiving stents for off-label indications have more adverse outcomes.[11][12]
