Abstract Background The main potential benefits of participating in a clinical trial is to have access to a treatment that is not available yet and to have a regular and careful attention from physicians. Several data have suggested that inclusion in a research study was associated with better clinical outcome. Aims The aim of this study is to describe the prevalence of inclusions in a research study (i.e., device or medication), clinical characteristics, management and clinical outcome in patients admitted for acute myocardial infarction (AMI) according to participation in a research study (versus not) using data from the French registries of Acute ST-or non-ST-elevation Myocardial infarction (FAST-MI) 2010 and 2015. Methods We used data from 2 one-month French registries, conducted 5 years apart, including 9,414 AMI admitted to coronary or intensive care units. We analyzed baseline characteristics, management and one-year survival according to participation in a research study. Results From 2010 to 2015, the prevalence of patients included in a research study decreased from 6.8% to 3.6% (P<0.001). Inclusions were performed mainly in university hospitals (8%). Clinical characteristics according to participation in a research study were strongly different. Overall, patients included in a research study were younger (61.2±12.7 vs 65.7±14.1; P<0.001) with less previous medical history and co-morbidities. Clinical presentation was preferentially a ST-elevation myocardial infarction (STEMI: 70% vs 52%; P<0.001) in these patients who had a lower GRACE score (133±32 vs. 141±35; P<0.001). The use of invasive strategies was more used in patients included in a research study (coronary angiogram: 99% vs 95%, P<0.001) as prescriptions of recommended medications (i.e., antiplatelet agents, beta-blockers, angiotensin-converting-enzyme inhibitor (ACE-I) or angiotensin receptor blocker (ARB) and statins) at discharge (72% vs 63%; P<0.001). In a cox multivariate analysis, participation in a research study was not associated with lower mortality at one-year (HR= 0.68, 95% CI, 0.39–1.18, P=0.17). Similar results were observed in patients discharge alive (HR= 0.81, 95% CI, 0.44–1.48, P=0.49). Recommended medications were however more used in patients included in a clinical trial (OR=1.34; 95% CI, 1.09–1.65; P=0.007). Conclusions The number of inclusions in a research study related to AMI in France is low. Our data suggest that patients included in a research study are selected and received more recommended medications and invasive strategies. However, this management is not associated with a lower mortality at one-year. Funding Acknowledgement Type of funding source: None

Background: Ischemic time has prognostic importance in ST-elevation myocardial infarction patients. Mobile intensive care unit use can reduce components of total ischemic time by appropriate triage of ST-elevation myocardial infarction patients. Methods: Data from the Acute Coronary Survey in Israel registry 2000–2010 were analyzed to evaluate factors associated with mobile intensive care unit use and its impact on total ischemic time and patient outcomes. Results: The study comprised 5474 ST-elevation myocardial infarction patients enrolled in the Acute Coronary Survey in Israel registry, of whom 46% ( n=2538) arrived via mobile intensive care units. There was a significant increase in rates of mobile intensive care unit utilization from 36% in 2000 to over 50% in 2010 ( p<0.001). Independent predictors of mobile intensive care unit use were Killip>1 (odds ratio=1.32, p<0.001), the presence of cardiac arrest (odds ratio=1.44, p=0.02), and a systolic blood pressure <100 mm Hg (odds ratio=2.01, p<0.001) at presentation. Patients arriving via mobile intensive care units benefitted from increased rates of primary reperfusion therapy (odds ratio=1.58, p<0.001). Among ST-elevation myocardial infarction patients undergoing primary reperfusion, those arriving by mobile intensive care unit benefitted from shorter median total ischemic time compared with non-mobile intensive care unit patients (175 (interquartile range 120–262) vs 195 (interquartile range 130–333) min, respectively ( p<0.001)). Upon a multivariate analysis, mobile intensive care unit use was the most important predictor in achieving door-to-balloon time <90 min (odds ratio=2.56, p<0.001) and door-to-needle time <30 min (odds ratio=2.96, p<0.001). One-year mortality rates were 10.7% in both groups (log-rank p-value=0.98), however inverse propensity weight model, adjusted for significant differences between both groups, revealed a significant reduction in one-year mortality in favor of the mobile intensive care unit group (odds ratio=0.79, 95% confidence interval (0.66–0.94), p=0.01). Conclusions: Among patients with ST-elevation myocardial infarction, the utilization of mobile intensive care units is associated with increased rates of primary reperfusion, a reduction in the time interval to reperfusion, and a reduction in one-year adjusted mortality.
