AIMS: We compared invasive (on-site coronary angioplasty or emergency air-ambulance transfer for bypass grafting surgery) vs conservative (persistent medical treatment) strategies in the management of refractory unstable angina in geographically isolated hospitals without cardiac surgical facilities. METHODS AND RESULTS: One hundred and forty eight randomized patients with refractory unstable angina were compared on an intention-to-treat basis. Outcomes (invasive vs conservative): (a) in hospital: stabilization (96% vs 43%, P=0.0001), non-fatal myocardial infarction (2.6% vs 4.2%, P=ns), death (1.3% vs 8.3%, P=0.046), combined outcome (3.9% vs 12.5%, P=0.053) and hospitalization (11.4+/-6.3 vs 12.4+/-8.0 days, P=ns). (b) 30-days follow-up: non-fatal myocardial infarction (2.6% vs 4.2%, P=ns), death (2.6% vs 11.1%, P=0.030) and combined outcome (5.3% vs 15.3%, P=0.031). (c) 12 month follow-up: non-fatal myocardial infarction (3. 9% vs 4.2%, P=ns), death (3.9% vs 12.5%, P=0.053), combined outcome (7.9% vs 16.7%, P=ns), re-admissions for unstable angina: (17.1% vs 23.6%, P=ns), late coronary angioplasty: (15.8% vs 11.1%, P=ns) and (d) late coronary bypass grafting: (7.9% vs 12.5%, P=ns). CONCLUSION: Invasive treatment of patients with refractory angina in remote areas without surgical back-up results in significant in-hospital stabilization and a reduction in major events in-hospital and at 30 days. Coronary angioplasty in stand-alone units and air-transfer of these patients seems safe. Copyright 2000 The European Society of Cardiology.
