ObjectiveRoutine evaluation of performance measures for the system of care for patients with ST-elevation myocardial infarction (STEMI) is needed to improve the STEMI network. We sought to evaluate the current status of reperfusion therapy for STEMI in the capital city of a developing country where a STEMI network was introduced in 2010.MethodsData were obtained from a local registry. A total of 28 812 patients admitted to the emergency department of a national cardiovascular hospital in three different periods (2007, 2010 and 2013) were retrospectively analysed; there were 2703 patients with STEMI.ResultsIn 2013 compared with 2007, there was a major increase in the number of primary percutaneous coronary interventions (PCIs) (35% vs 24%, p<0.001), and the proportion of non-reperfused patients fell (62.8% vs 67.7%, p<0.001). An improvement in the overall STEMI mortality rate was also observed (7.5% vs 11.7%, p<0.001).ConclusionsImplementation of a regional system of care for STEMI may improve utilisation of primary PCI. Future organisation of reperfusion therapy in a developing country such as Indonesia strongly calls for a strategy that focuses on prehospital care to minimise delay from the first medical contact to reperfusion therapy, and this may reduce the proportion of non-reperfused patients. These strategies are in concordance with guideline recommendations and may reduce or eliminate gaps in healthcare in developing countries, particularly the underutilisation of evidence-based therapies for patients with STEMI.Trial registration numberNCT 02319473, Clinicaltrials.gov.
Objective We studied the characteristics of patients with ST segment elevation myocardial infarction (STEMI) after expansion of a STEMI registry as part of the STEMI network programme in a metropolitan city and the surrounding area covering ∼26 million inhabitants. Design Retrospective cohort study. Setting Emergency department of 56 health centres. Participants 3015 patients with acute coronary syndrome, of which 1024 patients had STEMI. Main outcome measure Characteristics of reperfusion therapy. Results The majority of patients with STEMI (81%; N=826) were admitted to six academic percutaneous coronary intervention (PCI) centres. PCI centres received patients predominantly (56%; N=514) from a transfer process. The proportion of patients receiving acute reperfusion therapy was higher than non-reperfused patients (54% vs 46%, p<0.001), and primary PCI was the most common method of reperfusion (86%). The mean door-to-device (DTD) time was 102±68 min. In-hospital mortality of non-reperfused patients was higher than patients receiving primary PCI or fibrinolytic therapy (9.1% vs 3.2% vs 3.8%, p<0.001). Compared with non-academic PCI centres, patients with STEMI admitted to academic PCI centres who underwent primary PCI had shorter mean DTD time (96±44 min vs 140±151 min, p<0.001), higher use of manual thrombectomy (60.2% vs13.8%, p<0.001) and drug-eluting stent implantation (87% vs 69%, p=0.001), but had similar use of radial approach and intra-aortic balloon pump (55.7% vs 67.2%, and 2.2% vs 3.4%, respectively). In patients transferred for primary PCI, TIMI risk score ≥4 on presentation was associated with a prolonged door-in to door-out (DI-DO) time (adjusted OR 2.08; 95% CI 1.09 to 3.95, p=0.02). Conclusions In the expanded JAC registry, a higher proportion of patients with STEMI received reperfusion therapy, but 46% still did not. In developing countries, focusing the prehospital care in the network should be a major focus of care to improve the DI-DO time along with improvement of DTD time at PCI centres. Trial registration number NCT02319473.
AimGuideline implementation programs are of paramount importance in optimizing acute ST-elevation myocardial infarction (STEMI) care. Assessment of performance indicators from a local STEMI network will provide knowledge of how to improve the system of care.Methods and ResultsBetween 2008–2011, 1505 STEMI patients were enrolled. We compared the performance indicators before (n = 869) and after implementation (n = 636) of a local STEMI network. In 2011 (after introduction of STEMI networking) compared to 2008–2010, there were more inter-hospital referrals for STEMI patients (61% vs 56%, p<0.001), more primary percutaneous coronary intervention (PCI) procedures (83% vs 73%, p = 0.005), and more patients reaching door-to-needle time ≤30 minutes (84.5% vs 80.2%, p<0.001). However, numbers of patients who presented very late (>12 hours after symptom onset) were similar (53% vs 51%, NS). Moreover, the numbers of patients with door-to-balloon time ≤90 minutes were similar (49.1% vs 51.3%, NS), and in-hospital mortality rates were similar (8.3% vs 6.9%, NS) in 2011 compared to 2008–2010.ConclusionAfter a local network implementation for patients with STEMI, there were significantly more inter-hospital referral cases, primary PCI procedures, and patients with a door-to-needle time ≤30 minutes, compared to the period before implementation of this network. However, numbers of patients who presented very late, the targeted door-to-balloon time and in-hospital mortality rate were similar in both periods. To improve STEMI networking based on recent guidelines, existing pre-hospital and in-hospital protocols should be improved and managed more carefully, and should be accommodated whenever possible.
Routine performance measures of primary percutaneous coronary intervention (PCI) within an ST-segment elevation myocardial infarction (STEMI) network are needed to improve care.We evaluated the door-in to door-out (DI–DO) delays at the initial hospitals in STEMI patients as a routine performance measure of the metropolitan STEMI network.We retrospectively analyzed the DI–DO time from 1,076 patients with acute STEMI who were transferred by ground ambulance to a primary PCI center for primary PCI between 4 October 2014 and 1 April 2019. Correlation analysis between DI–DO times and total ischemia time was performed using Spearman's test. Logistic regression analyses were used to find variables associated with a longer DI–DO time.Median DI–DO time was 180 minutes (25th percentile to 75th percentile: 120–252 minutes). DI–DO time showed a positive correlation with total ischemia time (r = 0.4, p < 0.001). The median door-to-device time at the PCI center was 70 minutes (25th percentile to 75th percentile: 58–88 minutes). Multivariate analysis showed that women patients were independently associated with DI–DO time > 120 minutes (odds ratio 1.55, 95% confidence interval 1.03 to 2.33, p = 0.03).The DI–DO time reported in this study has not reached the guideline recommendation. To improve the overall performance of primary PCI in the region, interventions aimed at improving the DI–DO time at the initial hospitals and specific threat for women patients with STEMI are possibly the best efforts in improving the total ischemia time.
