In patients with multivessel coronary artery disease (MVD) the decision whether to treat a single culprit vessel or to perform multivessel revascularisation may be challenging. The purpose of this study was to evaluate the long-term outcome of multivessel percutaneous coronary intervention (MV-PCI) versus culprit vessel only (CV-PCI) in patients with stable coronary artery disease or non-ST elevation acute coronary syndrome.

Background: Patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) consists of a heterogenic population and improvement in identification of a specific risk profile is needed. In this study we aimed to obtain better insight in the role of different biomarkers for patients undergoing a routine invasive diagnostic strategy within 24 hours after admission. Methods: An Immediate or Early Invasive Strategy in Non-ST-Elevation Acute Coronary Syndrome (OPTIMA-2) study was a randomized controlled prospective open-label multicentre trial, randomizing NSTE-ACS patients. An invasive strategy was either immediate (<3 hours) or early (12–24 hours). Peak high-sensitive TroponinT (hsTropT) value was determined within the first 48 hours of admission. N-terminal proB-type natriuretic peptide (NTpro-BNP) and high-sensitivity C-reactive protein (hsCRP) values were determined at admission and at discharge. These biomarkers were then divided into tertiles and related to clinical outcomes up to one year. The relation between these biomarkers and myocardial function recovery established by echocardiography was analyzed as a secondary endpoint. Results: The OPTIMA-2 study included 249 patients. Overall, there was no significant increase in the risk of developing an adverse cardiovascular event in the first year if biomarker tertiles at admission were compared. However, mean NT-proBNP levels at admission were higher for patients that experienced all-cause death withing the first year (1.93 ± 0.49 vs 1.42 ± 0.58, p = 0.05). Also, peak hs-cTnT (232.0 ± 2846.0 vs 71.5 ± 1152.0, p = 0.06) values at baseline were higher in patients experiencing a myocardial infarction within 1-year. NT-proBNP levels at admission and at discharge correlated with recovery of the left ventricular (LV) function at 30 days (coefficient 0.021 (95% CI = 0.009–0.033) and coefficient 0.016 (95% CI = 0.005–0.027)). Conclusions: In NSTE-ACS patients treated by an early invasive strategy and administration of modern anticoagulant and antiplatelet therapy, multiple biomarker measurements during admission could not predict the occurrence of recurrent cardiovascular events within the first year of follow-up.

The timing of coronary angiography in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) remains a matter of debate. The relationship between the timing of invasive management and left ventricular function (LVF) is largely unknown. The An Immediate or Early Invasive Strategy in Non-ST-Elevation Acute Coronary Syndrome trial (OPTIMA-2) was a randomized controlled prospective open-label multicenter trial that randomized 249 NSTE-ACS patients to either an immediate (<3 h) invasive treatment strategy or an early strategy (12–24 h). Patients were pre-treated with a combination of aspirin, ticagrelor and fondaparinux. The aim of this prespecified sub-analysis was to assess (the recovery of) left ventricular function by analysing echocardiography data obtained <72 h after admission and at 30-day follow-up, for patients with a confirmed diagnosis of acute coronary syndrome. LVF was determined using ejection fraction (EF) and global longitudinal strain (GLS). Inter-observer variability was tested. No difference in the recovery of EF was found between an immediate and early strategy if the follow-up echocardiograms were compared to baseline: 2.5% (standard deviation (SD): 7.9) and 3.3% (SD: 8.5), p = 0.51, nor was there any difference in GLS recovery between the study groups: −0.8% (SD: 2.5) vs. −0.7% (SD 2.8) p = 0.82. If baseline and follow-up echocardiograms were compared, there was a similar but significant improvement in both EF and GLS in both separate study groups. An immediate invasive strategy in NSTE-ACS patients did not result in an improved left ventricular EF or GLS recovery compared with an early strategy.
