Revascularization in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome (NSTE-ACS) With Multivessel and/or Unprotected Left Main Coronary Disease (MILESTONE)
Recruitment status was: Not yet recruiting
MILESTONE STUDY is dedicated to problems connected with patients with multivessel coronary artery disease and/or with left main narrowing who present symptoms of acute ischemia. For such kind of patients according to current ACC/AHA guidelines CABG (surgical revascularization) is recommended as a treatment method. In comparison with CABG, recent studies have shown that PCI (percutaneous coronary intervention) is associated with a lower rate of periprocedural adverse events and similar long term event-free survival in patients with left main disease. Our latest non randomized registry and randomized LEMANS study, comparing LMCA (left main coronary artery) stenting with CABG confirmed above findings. LEMANS ACS (acute coronary syndrome) retrospective registry of patients with UPLMCA (unprotected LMCA) disease and non ST elevation ACS showed lower 30 day and trend toward lower one year mortality after PCI when compared with CABG. It should be stressed, that acute ischemia substantially increase the risk of CABG. In fact, there are limited data on the outcome of ULMCA stenting or CABG in patients with acute coronary syndromes (ACS).
Similarly, all randomized studies comparing PCI vs CABG in multivessel disease included mainly patients with stable angina, small cohort of patients with unstable angina and they excluded patients with non ST elevation Myocardial infarction.
In the SYNTAX study -largest PCI vs CABG trial, randomized patients were patients with low perioperative risk (logistic EUROSCORE <5) and ACS patients routinely excluded. High perioperative risk patients were included only in PCI registry.

|Official Title:||Revascularization Strategy (PCI With DES Implantation vs CABG) in Patients With Non ST Elevation Acute Coronary Syndrome With Multivessel and/or Unprotected Left Main Coronary Disease|
- All cause death [ Time Frame: One year after revascularization procedure ] [ Designated as safety issue: No ]The primary endpoint is a composite of all death one year after revascularization procedure: PCI or CABG. The hypothesis test is designed to show non-inferiority of PCI to CABG for the primary endpoint
- Composite of MACCE [ Time Frame: peri-hospital period, one month and one year after revascularization procedure ] [ Designated as safety issue: No ]MACCE is defined as: all death, myocardial infarction, stroke, or unplanned revascularization
- Procedural and post procedural complication [ Time Frame: peri-hospital period, one month and one year after revascularization procedure ] [ Designated as safety issue: No ]Procedural and post procedural complication: length of hospital stay and frequency of prolonged hospitalization ; return to work; readmissions and cause of readmissions; angina and functional status; medications.
- Overall costs of treatment strategies. [ Time Frame: one year ofter revascularization procedure ] [ Designated as safety issue: No ]Hospital costs and long-term cost-effectiveness.
- Occurence of stent thrombosis or graft occlusion [ Time Frame: peri-hospital period, one month and one year after revascularization procedure ] [ Designated as safety issue: No ]Stent trombosis will be defined in accordance with ARC definition.
- Hemorrhagic complications. [ Time Frame: peri-hospital period, one month and one year after revascularization procedure ] [ Designated as safety issue: No ]Hemorrhagic complications will be clasified according to TIMI scale.
- Frequency and impact of complete revascularization [ Time Frame: one year after revascularization procedure ] [ Designated as safety issue: No ]Complete revascularization will be defined on an anatomic basis and by revascularization of all significant ischemic areas.
