The comparison among complete, incomplete revascularization referred by myocardial perfusion imaging and medical therapy for coronary disease patients

239 Objectives To compare the long-term outcomes of patients treated by complete revascularization (CR) or incomplete revascularization (IR), referred by myocardial perfusion imaging (MPI), and by medical therapy only, then further to evaluate the impact of extent of myocardial ischemia and different strategy (CR, IR and medical therapy) on the prognosis of coronary artery disease (CAD) patients. Methods ​Two hundred and eighty-six consecutive patients with abnormal angiography and myocardial ischemia were consecutively followed for 45 ± 21 months. Patients were divided into CR, IR and medical therapy three groups, or into two subgroups by 10% ischemic myocardium. Death and major adverse cardiac events (MACEs) were defined as endpoints. Results There was no difference between revascularization and medical therapy (survival: P = 0.158).CR was associated with outcomes better than IR and medical therapy (survival: P = 0.019, MACE-free survival: P Conclusions Complete revascularization could lead to outcomes better than incomplete one and medical therapy, especially when patients had ischemic myocardium more than 10%. However, there was no difference between incomplete revascularization and medical therapy.
