Detailed Description

Invasive coronary angiography followed by percutaneous coronary intervention is the treatment of choice in patient presenting with STEMI-ACS1 and NSTE-ACS2. Up to 60 percent of these patients have multivessel disease on angiography3-5. Patients with multivessel disease have a worse prognosis compared with patients having culprit vessel disease only5. It has been debated whether a complete or culprit artery only revascularization strategy is better.

Retrospective data in STEMI patients suggested a lower mortality in patients that were treated with culprit artery only compared with multivessel PCI during index procedure6. Since then, four randomized controlled trials have addressed this question in STEMI population; The Randomized Trial of Preventive Angioplasty in Acute Myocardial Infarction (PRAMI) trial (n = 465, 23 months follow-up)7, the Randomized trial of complete versus lesion-only revascularization in patients undergoing primary percutaneous coronary intervention for STEMI and multivessel disease (CvLPRIT) (n = 296, 12months follow-up)8, the Complete revascularisation versus treatment of the culprit lesion only in patients with ST-segment elevation myocardial infarction and multivessel disease (DANAMI-3-PRIMULTI) trial (n = 627, 27months follow-up)9, and the Fractional Flow Reserve-Guided Multivessel Angioplasty in Myocardial Infarction (Compare-Acute) trial (n = 885, 12 months follow-up)10. PCI of the non-infarct related artery was performed at the index procedure (PRAMI and Compare-Acute), staged before discharge (DANAMI-3-PRIMULTI) or at any time during hospitalization (CvLPRIT). Indication for PCI was significant stenosis as assessed by angiography (PRAMI and CvLPRIT) or FFR (DANAMI-3-PRIMULTI and COMPARE-ACUTE). There was a significant reduction in primary outcome in all four trials in favor of complete revascularization. However, there was no significant reduction in total mortality or myocardial infarction. Based on the results for these four trials, the 2017 ESC STEMI-ACS guidelines gave a class II, level of evidence (LOE) A, indication for routine complete revascularization in STEMI patients with multivessel disease, including those presenting with cardiogenic shock1. However, an important shortcoming of the abovementioned studies is the absence of a staged complete revascularization arm. As there is no data that compare immediate and staged complete revascularization, the guidelines don't advise on when to perform non-infarct related artery revascularization.

Data regarding optimal treatment in NSTEMI-ACS are more scarce. In an observational study by Shishesbor and coworkers, they showed that nonculprit multivessel stenting reduced future revascularization rate but this was not associated with lower rate of death or myocardial infarction11. Recently, a substudy from the Bleeding complications in a Multicenter registry of patients discharged with diagnosis of acute coronary syndrome (BleeMACS) registry (N=4520 patients, 1459 NSTEMI) was published12. They showed that in NSTEMI patients, complete revascularization was associated with a significant lower rate of death (4.5% vs. 8.5%; p=0.002), re-AMI (3.7% vs. 6.6%; p=0.016) and MACE (8.1% vs. 13.9%; p=0.001) at one year follow up. The 2015 ESC NSTEMI-ACS guidelines not specifically advise a culprit only or multivessel PCI strategy. Moreover, they advise to base revascularization strategy on patients clinical status and co-morbidities, as well as disease severity, Class II, LEO B. Interestingly, in contrast with the STEMI population, in NSTEMI population there is a small RCT investigating staged versus direct complete revascularization , the Single-Staged Compared With Multi-Staged PCI in Multivessel NSTEMI Patients: The SMILE Trial (N=584 patients)13. There was a significant reduction in primary endpoint 1S-PCI: n = 36 [13.63%] vs. MS-PCI: n = 61 [23.19%]; hazard ratio [HR]: 0.549 [95% confidence interval (CI): 0.363 to 0.828]; p = 0.004) at one year follow up. This was mainly driven by a reduction in target vessel revascularization. There was no significant difference in cardiac death or myocardial infarction between the both groups. This finding deserves further investigation, because the TVR rate (15.4% at 1 year) in the multistage group was unprecedentedly high in the era of current-generation drug-eluting stents.

There is no publication specifically addressing the patients with unstable angina regarding the subject of complete or incomplete revascularization or timing of revascularization.

Considering such data, complete revascularization in ACS patients seems advisable, but timing of revascularization is unknown.

Given this background no investigation so far provided a comprehensive evaluation of the complete revascularization strategies for patients with any type of acute coronary syndrome and multivessel disease. Therefore, the investigators aim to investigate in a randomized controlled trial the commonly used complete revascularization strategies for patients presenting with ACS: 1) Immediate complete revascularization 2) Culprit only plus staged complete revascularization within six weeks after index procedure, in terms of the primary endpoint, the composite of death from any cause, nonfatal type 1 myocardial infarction, revascularization, and cerebrovascular events at 1-year post intervention.

Patients will be treated with one commercially available second-generation drug-eluting stent stent to ensure homogeneity of treatment among patients, abolishing the occurrence of bias due to different stent usage. The stents used will be the Biotronik Orsiro DES (Sirolimus-Eluting stent). The Orsiro DES is a second generation DES with a bioabsorbable polymer coating releasing sirolimus and was CE marketed in 2011. The bioabsorbable nature of the polymer could be associated with a reduction of the inflammatory response, reducing neo-intima growth compared to a durable polymer14, 15. The active drug sirolimus is a lipophilic molecule that inhibits mammalian target of rapamycine (mTOR) on smooth muscle cells, also preventing neo-intima hyperplasia16. The Orsiro stent has ultrathin cobalt chromium struts of 60-80micron (depending on stent size) enhancing deliverability and crossability without loss of radial strength or fatigue resistance. The Orsiro stent has been extensively studied in different study populations with more than 32.500 patients studied globally.

Placebo Comparator: Staged complete revascularization
• Culprit only + staged (within six weeks after index procedure) complete revascularization in all vessels ≥ 2.5mm with ≥ 70% stenosis by visual estimation or positive coronary physiology test per operator's discretion (Control arm)
At the index procedure, the culprit lesion (cause of complaints/acute coronary syndrome) will be treated according to standard of care with a Biotronik Orsiro DES (Sirolimus-Eluting stent). If there are additional significant lesions besides the culprit lesion, patients will be randomized to direct complete revascularization or staged complete revascularization. In the direct complete revascularization group all lesions will be treated during the index procedure. In the staged complete revascularization group, only the culprit lesion will be treated during the index procedure. The remaining significant lesions will be treated later but within six weeks after the index procedure. In both arms the additional lesions will also be treated with Biotronik Orsiro DES (Sirolimus-Eluting stent).
