Stopyra JP, Snavely AC, Ashburn NP, Supples MW, Brown WM, Miller CD, Mahler SA. Rural EMS STEMI Patients - Why the Delay to PCI? PREHOSP EMERG CARE 2024:1-8. [PMID: 38235978 DOI: 10.1080/10903127.2024.2305967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 12/13/2023] [Indexed: 01/19/2024]
Abstract
BACKGROUND The objective of this study is to identify patient and EMS agency factors associated with timely reperfusion of patients with ST-elevation myocardial infarction (STEMI). METHODS We conducted a cohort study of adult patients (≥18 years old) with STEMI activations from 2016 to 2020. Data was obtained from a regional STEMI registry, which included eight rural county EMS agencies and three North Carolina percutaneous coronary intervention (PCI) centers. On each patient, prehospital and in-hospital time intervals were abstracted. The primary outcome was the ability to achieve the 90-minute EMS FMC to PCI time goal (yes vs. no). We used generalized estimating equations accounting for within-agency clustering to evaluate the association between patient and agency factors and meeting first medical contact (FMC) to PCI time goal while accounting for clustering within the agency. RESULTS Among 365 rural STEMI patients 30.1% were female (110/365) with a mean age of 62.5 ± 12.7 years. PCI was performed within the time goal in 60.5% (221/365) of encounters. The FMC to PCI time goal was met in 45.5% (50/110) of women vs 69.8% (178/255) of men (p < 0.001). The median PCI center activation time was 12 min (IQR 7-19) in the group that received PCI within the time goal compared to 21 min (IQR 10-37) in the cohort that did not. After adjusting for loaded mileage and other clinical variables (e.g., pulse rate, hypertension etc.), the male sex was associated with an improved chance of meeting the goal of FMC to PCI (aOR: 2.94; 95% CI 2.11-4.10) compared to the female sex. CONCLUSION Nearly 40% of rural STEMI patients transported by EMS failed to receive FMC to PCI within 90 min. Women were less likely than men to receive reperfusion within the time goal, which represents an important health care disparity.

Abstract
Ischemic heart disease is the greatest health burden and most frequent cause of death worldwide. Myocardial ischemia/reperfusion is the pathophysiological substrate of ischemic heart disease. Improvements in prevention and treatment of ischemic heart disease have reduced mortality in developed countries over the last decades, but further progress is now stagnant, and morbidity and mortality from ischemic heart disease in developing countries are increasing. Significant problems remain to be resolved and require a better pathophysiological understanding. The present review attempts to briefly summarize the state of the art in myocardial ischemia/reperfusion research, with a view on both its coronary vascular and myocardial aspects, and to define the cutting edges where further mechanistic knowledge is needed to facilitate translation to clinical practice.

Abstract
BACKGROUND ST-elevation myocardial infarction (STEMI) guidelines recommend an emergency medical services (EMS) first medical contact (FMC) to percutaneous coronary intervention (PCI) time of ≤90 min. The primary objective of this study was to evaluate the association between FMC to PCI time and mortality in rural STEMI patients. METHODS We conducted a cohort study of patients ≥18 years old with STEMI activations from January 2016 to March 2020. Data were obtained from a rural North Carolina Regional STEMI Data Registry, which included eight rural EMS agencies and three PCI centers, the National Cardiovascular Data Registry, and the EMS electronic health record. Prehospital and in-hospital time intervals were digitally abstracted. The outcome of index hospitalization mortality was compared between patients who did and did not meet FMC to PCI time goal using Fisher's exact tests. Negative predictive value (NPV) for index hospitalization death was calculated with 95% confidence intervals (CIs). A receiver operating characteristic curve was constructed and an optimal FMC to PCI time goal was identified by maximizing NPV to prevent index hospitalization death. RESULTS Among 365 rural EMS STEMI patients, 30.1% (110/365) were female with a mean ± SD age of 62.5 ± 12.7 years. PCI was performed within the 90-min time goal in 60.5% (221/365) of patients. Among these patients, 3% (11/365) died during initial STEMI hospitalization, with 1.4% (3/221) mortality in the group that met the 90-minute time goal compared to 5.6% (8/144) in patients exceeding the time goal (p = 0.03). Meeting the 90-min time goal yielded a 98.6% (95% CI 96.1%-99.7%) NPV for index death. A 78-min FMC to PCI time was the optimal cut point, yielding a NPV for index mortality of 99.3% (95% CI 96.1%-100%). CONCLUSIONS Death among rural patients with STEMI was four times more likely when they did not receive PCI within 90 min.

Abstract
ABSTRACT: The American Heart Association Mission: Lifeline program objectives are to improve the quality of care and outcomes for patients with ST‐segment–elevation myocardial infarction. Every minute of delay in treatment adversely affects 1‐year mortality. Transfer of patients safely and timely to hospitals with primary percutaneous coronary intervention capability is needed to improve outcomes. But treatment times continue to show delays, especially during interhospital transfers. A simple 3‐step process of an interhospital “Call 9‐1‐1” protocol may expedite this process. This STAT TRANSFER process uses a systems approach that considers diverse ways in which patients access care, how EMS responds and determines destinations, how referring hospital transfers are performed, urban and rural differences, and how receiving hospitals prepare for an incoming patient with ST‐segment–elevation myocardial infarction. This initiative suggests a strategy to reduce variability in interhospital transfer times using a STAT TRANSFER and a Call 9‐1‐1 process in a system of care that involves all stakeholders.

Abstract
Background Pharmaco-invasive therapy (PIT), combining thrombolysis and percutaneous coronary intervention, was a potential complement for primary percutaneous coronary intervention (pPCI), while bleeding risk was still a concern. Objectives This study aims to compare the efficacy and safety outcomes of PIT and pPCI. Methods A systematic search for randomized controlled trials (RCTs) and observational studies were conducted on Pubmed, Embase, Cochrane library, and Scopus. RCTs and observational studies were all collected and respectively analyzed, and combined pooled analysis was also presented. The primary efficacy outcome was short-term all-cause mortality within 30 days, including in-hospital period. The primary safety outcome was 30-day trial-defined major bleeding events. Results A total of 26,597 patients from 5 RCTs and 12 observational studies were included. There was no significant difference in short-term mortality [RCTs: risk ratio (RR): 1.14, 95% CI: 0.67–1.93, I2 = 0%, p = 0.64; combined results: odds ratio (OR): 1.09, 95% CI: 0.93–1.29, I2 = 0%, p = 0.30] and 30-day major bleeding events (RCTs: RR: 0.44, 95% CI: 0.07–2.93, I2 = 0%, p = 0.39; combined results: OR: 1.01, 95% CI: 0.53–1.92, I2 = 0%, p = 0.98). However, pPCI reduced risk of in-hospital major bleeding events, stroke and intracranial bleeding, but increased risk of in-hospital heart failure and 30-day heart failure in combined analysis of RCTs and observational studies, despite no significant difference in analysis of RCTs. Conclusion Pharmaco-invasive therapy could be an important complement for pPCI in real-world clinical practice under specific conditions, but studies aiming at optimizing thrombolysis and its combination of mandatory coronary angiography are also warranted.

Abstract
OBJECTIVE Delays in care for patients with acute cardiac complaints are associated with increased morbidity and mortality. The objective of this study was to quantify rural and urban differences in prehospital time intervals for patients with cardiac complaints. METHODS The ESO Data Collaborative dataset consisting of records from 1332 EMS agencies was queried for 9-1-1 encounters with acute cardiac problems among adults (age ≥ 18) from 1/1/2013-6/1/2018. Location was classified as rural or urban using the 2010 United States Census. The primary outcome was total prehospital time. Generalized estimating equations evaluated differences in the average times between rural and urban encounters while controlling for age, sex, race, transport mode, loaded mileage, and patient stability. RESULTS Among 428,054 encounters, the median age was 62 (IQR 50-75) years with 50.7% female, 75.3% white, and 10.3% rural. The median total prehospital, response, scene, and transport times were 37.0 (IQR 29.0-48.0), 6.0 (IQR 4.0-9.0), 16.0 (IQR 12.0-21.0), and 13.0 (IQR 8.0-21.0) minutes. Rural patients had an average total prehospital time that was 16.76 min (95%CI 15.15-18.38) longer than urban patients. After adjusting for covariates, average total time was 5.08 (95%CI 4.37-5.78) minutes longer for rural patients. Average response and transport time were 4.36 (95%CI 3.83-4.89) and 0.62 (95%CI 0.33-0.90) minutes longer for rural patients. Scene time was similar in rural and urban patients (0.09 min, 95%CI -0.15-0.33). CONCLUSION Rural patients with acute cardiac complaints experienced longer prehospital time than urban patients, even after accounting for other key variables, such as loaded mileage.

Abstract
Notable racial and ethnic differences and disparities exist in coronary artery disease (CAD) and stroke epidemiology and outcomes despite substantial advances in these fields. Racial and ethnic minority subgroups remain underrepresented in population data and clinical trials contributing to incomplete understanding of these disparities. Differences in traditional cardiovascular risk factors such as hypertension and diabetes play a role; however, disparities in care provision and process, social determinants of health including socioeconomic position, neighborhood environment, sociocultural factors, and racial discrimination within and outside of the health care system also drive racial and ethnic CAD and stroke disparities. Improved culturally congruent and competent communication about risk factors and symptoms is also needed. Opportunities to achieve improved and equitable outcomes in CAD and stroke must be identified and pursued.

Abstract
BACKGROUND ST-segment elevation myocardial infarction (STEMI) requires prompt therapy. It is recommended for door-to-balloon (DTB) times to be less than 90 minutes. In the United States, some locations have difficulty meeting this goal. OBJECTIVE The objective of this study was to determine whether implementation of a STEMI network decreased DTB times at a large, STEMI-receiving, metropolitan academic hospital in the southeastern United States. Furthermore, differences among presentation types, including walk-in, emergency medical services, and transfers, were explored. METHODS A pre-post time series study of electronic medical record data was conducted to evaluate the efficacy of a STEMI network. RESULTS The sample included 127 patients with a diagnosis of STEMI, collected during 3 periods (T1, T2, and T3). Patients were primarily White (78.0%) and male (67.7%), with a mean (SD) age of 58.9 (13.9) years. The 1-way analysis of variance revealed a significant difference in overall DTB times, F2 = 11.66, P < .001. Post hoc comparisons indicated longer mean DTB times for T1 compared with T3 (P < .001) and T2 (P < .001). When exploring presentation type, 1-way analysis of variance revealed a significant difference in mean DTB times in transfer patients between T1 and T2 (P < .001) and T1 to T3 (P < .001). No other statistical differences were noted; however, all DTB times with the exception of T2 for emergency medical services presentation decreased. CONCLUSIONS Implementation of a STEMI network was effective at decreasing overall DTB times with patients who presented to the hospital with a diagnosis of STEMI.

Abstract
ST-segment elevation myocardial infarction is a medical emergency with significant health care delivery challenges to ensure rapid triage and treatment. Several developments over the past decades have led to improved care delivery, decreased time to reperfusion, and decreased mortality. Still, significant challenges remain to further optimize the delivery of care for this patient population.

Abstract
ST elevation myocardial infarction diagnoses have reduced in number over the past 10 years; however, associated morbidity and mortality remain high. Societal guidelines focus on early diagnosis and timely access to reperfusion, preferably percutaneous coronary intervention (PCI), with fibrinolytics reserved for those who cannot receive timely PCI. Proposed algorithms recommend emergency department bypass in stable patients with a clear diagnosis to reduced door-to-balloon time. Emergency providers should limit their evaluation, focusing on life-threatening comorbidities, unstable vitals, or contraindications to a catheterization laboratory. In-hospital patients prove diagnostically challenging because they may be unable to express symptoms, and reperfusion strategies can complicate other diagnoses.

Abstract
Appropriate risk stratification and timely revascularization of acute myocardial infarction (AMI) are available in percutaneous coronary intervention (PCI) - capable hospitals (PCHs). This study evaluated whether direct admission vs inter-hospital transfer influences cardiac mortality in patients with AMI. This study was conducted in the PCH where the patients were able to arrive within an hour. The inclusion criteria were AMI with a symptom onset time within 24 hours and having undergone PCI within 24 hours after admission. The cumulative incidence of cardiac death after percutaneous coronary intervention was evaluated in the direct admission versus inter-hospital transfer groups. Among the 3178 patients, 2165 (68.1%) were admitted via inter-hospital transfer. Patients with ST-segment elevation myocardial infarction (STEMI) in the direct admission group had a reduced symptom onset-to-balloon time (121 minutes, P < .001). With a median period of 28.4 (interquartile range, 12.0-45.6) months, the cumulative incidence of 2-year cardiac death was lower in the direct admission group (NSTEMI, 9.0% vs 11.0%, P = .136; STEMI, 9.7% vs 13.7%, P = .040; AMI, 9.3% vs 12.3%, P = .014, respectively). After the adjustment for clinical variables, inter-hospital transfer was the determinant of cardiac death (hazard ratio, 1.59; 95% confidence interval, 1.08-2.33; P = .016). Direct PCH admission should be recommended for patients with suspected AMI and could be a target for reducing cardiac mortality.

[PMID: 33856318 PMCID: PMC7972365 DOI: 10.5811/westjem.2020.8.47770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 08/30/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Despite large-scale quality improvement initiatives, substantial proportions of patients with ST-elevation myocardial infarction (STEMI) transferred to percutaneous coronary intervention centers do not receive percutaneous coronary intervention within the recommended 120 minutes. We sought to examine the contributory role of emergency medical services (EMS) activation relative to percutaneous coronary intervention center activation in the timeliness of care for patients transferred with STEMI. Methods We conducted a retrospective analysis of interfacility transfers from emergency departments (ED) to a single percutaneous coronary intervention center between 2011–2014. We included emergency department (ED) patients transferred to the percutaneous coronary intervention center and excluded scene transfers and those given fibrinolytics. We calculated descriptive statistics and used multivariable linear regression to model the association of variables with ED time intervals (arrival to electrocardiogram [ECG], ECG-to-EMS activation, and ECG-to-STEMI alert) adjusting for patient age, gender, mode of arrival, weekday hour presentation, facility transfers in the past year, and transferring facility distance. Results We identified 159 patients who met inclusion criteria. Subjects were a mean of 59 years old (standard deviation 13), 22% female, and 93% White; 59% arrived by private vehicle, and 24% presented after weekday hours. EDs transferred a median of 9 STEMIs (interquartile range [IQR] 3, 15) in the past year and a median of 65 miles (IQR 35, 90) from the percutaneous coronary intervention center. Median ED length of stay was 65 minutes (IQR 51, 85). Among component intervals, arrival to ECG was 6%, ECG-to-EMS activation 32%, and ECG-to-STEMI alert was 49% of overall ED length of stay. Only 18% of transfers had EMS activation earlier than STEMI alert. ECG-to-EMS activation was shorter in EDs achieving length of stay ≤60 minutes compared to those >60 minutes (12 vs 31 minutes, P<0.001). Multivariable modeling showed that after-hours presentation was associated with longer ECG-to-EMS activation (adjusted relative risk [RR] 1.05, P<0.001). Female gender (adjusted RR 0.81, P<0.001), prior facility transfers (adjusted RR 0.84, P<0.001), and initial ambulance presentation (adjusted RR 0.93, P = 0.02) were associated with shorter ECG-to-EMS activation. Conclusion In STEMI transfers, faster EMS activation was more likely to achieve a shorter ED length of stay than a rapid, percutaneous coronary intervention center STEMI alert. Large-scale quality improvement efforts such as the American Heart Association’s Mission Lifeline that were designed to regionalize STEMI have improved the timeliness of reperfusion, but major gaps, particularly in interfacility transfers, remain. While the transferring EDs are recognized as the primary source of delay during interfacility STEMI transfers, the contributions to delays at transferring EDs remain poorly understood.

Understanding timely STEMI treatment performance: A 3-year retrospective cohort study using diagnosis-to-balloon-time and care subintervals. J Am Coll Emerg Physicians Open 2021; 2:e12379. [PMID: 33644777 PMCID: PMC7890036 DOI: 10.1002/emp2.12379] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 01/07/2021] [Accepted: 01/13/2021] [Indexed: 01/22/2023] Open
Abstract
OBJECTIVE From the perspective of percutaneous coronary intervention (PCI) centers, locations of ST-segment elevation myocardial infarction (STEMI) diagnosis can include a referring facility, emergency medical services (EMS) transporting to a PCI center, or the PCI center's emergency department (ED). This challenges the use of door-to-balloon-time as the primary evaluative measure of STEMI treatment pathways. Our objective was to identify opportunities to improve care by quantifying differences in the timeliness of STEMI treatment mobilization based on the location of the diagnostic ECG. METHODS This 3-year, single-center, retrospective cohort study classified patients by diagnostic ECG location: referring facility, EMS, or PCI center ED. We quantified door-to-balloon-time and diagnosis-to-balloon-time with its care subintervals. RESULTS Of 207 ED STEMI patients, 180 (87%) received PCI. Median diagnosis-to-balloon-times were shortest among the ED-diagnosed (78 minutes [interquartile range (IQR), 61-92]), followed by EMS-identified patients (89 minutes [IQR, 78-122]), and longest among those referred (140 minutes [IQR, 119-160]), reflecting time for transport to the PCI center. Conversely, referred patients had the shortest median door-to-balloon-times (38 minutes [IQR, 34-43]), followed by the EMS-identified (64 minutes [IQR, 47-77]), whereas ED-diagnosed patients had the longest (89 minutes [IQR, 70-114]), reflecting diagnosis and catheterization lab activation frequently occurring before PCI center ED arrival for referred and EMS-identified patients. CONCLUSIONS Diagnosis-to-balloon-time and its care subintervals are complementary to the traditional door-to-balloon-times as measures of the STEMI treatment process. Together, they highlight opportunities to improve timely identification among ED-diagnosed patients, use of out-of-hospital cath lab activation for EMS-identified patients, and encourage pathways for referred patients to bypass PCI center EDs.

Abstract
BACKGROUND Little is known about the effect of the coronavirus disease 2019 (COVID-19) pandemic and the outbreak response measures on door-to-balloon time (D2B). This study examined both D2B and clinical outcomes of patients with STEMI undergoing primary percutaneous coronary intervention (PPCI).Methods and Results:This was a retrospective study of 303 STEMI patients who presented directly or were transferred to a tertiary hospital in Singapore for PPCI from October 2019 to March 2020. We compared the clinical outcomes of patients admitted before (BOR) and during (DOR) the COVID-19 outbreak response. The study outcomes were in-hospital death, D2B, cardiogenic shock and 30-day readmission. For direct presentations, fewer patients in the DOR group achieved D2B time <90 min compared with the BOR group (71.4% vs. 80.9%, P=0.042). This was more apparent after exclusion of non-system delay cases (DOR 81.6% vs. BOR 95.9%, P=0.006). Prevalence of both out-of-hospital cardiac arrest (9.5% vs. 1.9%, P=0.003) and acute mitral regurgitation (31.6% vs. 17.5%, P=0.006) was higher in the DOR group. Mortality was similar between groups. Multivariable regression showed that longer D2B time was an independent predictor of death (odds ratio 1.005, 95% confidence interval 1.000-1.011, P=0.029). CONCLUSIONS The COVID-19 pandemic and the outbreak response have had an adverse effect on PPCI service efficiency. The study reinforces the need to focus efforts on shortening D2B time, while maintaining infection control measures.

Abstract
Myocardial elastography (ME) is an ultrasound-based strain imaging method that aims to determine the degree of ischemia or infarction as a result of the change in the elastic properties of the myocardium. A survival canine model (n = 11) was employed to investigate the ability of ME to image myocardial infarction formation and recovery. Infarcts were generated by ligation of the left anterior descending coronary artery. Canines were survived and imaged for 4 days (n = 7) or 4 weeks (n = 4), allowing sufficient time for recovery via collateral perfusion. A radial strain-based metric, percentage of healthy myocardium by strain (PHMε), was developed as a marker for healthy myocardial tissue. PHMε was strongly linearly correlated with actual infarct size as determined by gross pathology (R2 = 0.80). Mean PHMε was reduced 1-3 days post-infarction (p < 0.05) at the papillary and apical short-axis levels; full infarct recovery was achieved by day 28, with mean PHMε returning to baseline levels. ME was capable of diagnosing individual myocardial segments as non-infarcted or infarcted with high sensitivity (82%), specificity (92%) and precision (85%) (area under the receiver operating characteristic curve = 0.90). The study therefore strengthens the ME premise that it can detect and assess myocardial infarction progression and recovery in vivo and could thus provide an important role in both disease diagnosis and treatment assesssment.

Abstract
Background Despite regionalization efforts, delays at transferring hospitals for patients transferred with ST-elevation myocardial infarction (STEMI) for primary percutaneous coronary intervention (PCI) persist. These delays primarily occur in the emergency department (ED), and are associated with increased mortality. We sought to use qualitative methods to understand staff and clinician perceptions underlying these delays. Methods We conducted semi-structured interviews at 3 EDs that routinely transfer STEMI patients to identify staff perceptions of delays and potential interventions. Interviews were recorded, transcribed, coded, and analyzed using an iterative inductive-deductive approach to build and refine a list of themes and subthemes, and identify supporting quotes. Results We interviewed 43 ED staff (staff, nurses, and physicians) and identified 3 major themes influencing inter-facility transfers of STEMI patients: 1) Processes, 2) Communication; and 3) Resources. Standardized processes (i.e., protocols) reduce uncertainty and can mobilize resources. Use of performance benchmarks can motivate staff but are frequently focused on internal, not inter-organizational performance. Direct use ofcommunication between ORGANIZATIONS can process uncertainty and expedite care. Record sharing and regular post-transfer communication could provide opportunities to discuss and learn from delays and increase professional satisfaction. Finally, characteristics of resources that enhanced their capacity, clarity, experience, and reliability were identified as contributing to timely transfers. Conclusions Processes, communication, and resources were identified as modifying inter-facility transfer timeliness. Potential quality improvement strategies include ongoing updates of protocols within and between organizations to account for changes, enhanced post-transfer feedback between organizations, shared medical records, and designated roles for coordination.

Abstract
Background:
Catheterization laboratory (cath lab) activation time is a newly available process measure for patients with ST-segment–elevation myocardial infarction requiring inter-hospital transfers for primary percutaneous coronary intervention that reflects inter-facility communication and urgent mobilization of interventional laboratory resources. Our aim was to determine whether faster activation is associated with improved reperfusion time and outcomes in the American Heart Association Mission: Lifeline Accelerator-2 Project.
Methods and Results:
From April 2015 to March 2017, treatment times of 2063 patients with ST-segment–elevation myocardial infarction requiring inter-hospital transfer for primary percutaneous coronary intervention from 12 regions around the United States were stratified by cath lab activation time (first hospital arrival to cath lab activation within [timely] or beyond 20 minutes [delayed]). Median cath lab activation time was 26 minutes, with a delayed activation observed in 1241 (60.2%) patients. Prior cardiovascular or cerebrovascular disease, arterial hypotension at admission, and black or Latino ethnicity were independent factors of delayed cath lab activation. Timely cath lab activation patients had shorter door-in door-out times (40 versus 68 minutes) and reperfusion times (98 versus 135 minutes) with 80.1% treated within the national goal of ≤120 minutes versus 39.0% in the delayed group.
Conclusions:
Cath lab activation within 20 minutes across a geographically diverse group of hospitals was associated with performing primary percutaneous coronary intervention within the national goal of ≤120 minutes in >75% of patients. While several confounding factors were associated with delayed activation, this work suggests that this process measure has the potential to direct resources and practices to more timely treatment of patients requiring inter-hospital transfer for primary percutaneous coronary intervention.

Abstract
Background Patients with ST-elevation myocardial infarction (STEMI) presenting to percutaneous coronary intervention (PCI)-capable hospitals often experience delays for primary PCI (pPCI). We sought to describe the effect of specific delay intervals and patient/system-level factors on STEMI reperfusion times. Methods We analyzed all consecutive patients with STEMI who presented to 2 PCI-capable hospital emergency departments (EDs) between June 2007 and March 2016 who received successful pPCI. We excluded patients with prehospital cardiac arrest. We compared specific system delay intervals, patient characteristics, and in-hospital outcomes among patients who received timely (first medical contact-device ≤90/≤120 minutes) vs delayed >90/>120 minutes) pPCI. Results Of 1936 patients with STEMI, 1127 (58%) presented directly to a PCI-capable hospital via emergency health services (EHS), 499 (26%) were transferred from the ED of a non-PCI hospital, and 310 (16%) self-presented to the ED of a pPCI-capable hospital. Guideline-recommended reperfusion times were met in 47% of direct-EHS, 42% of transfers, and 33% of self-presenters. Each time interval from first medical contact to device deployment was significantly prolonged in the delayed vs timely reperfusion cohorts across all 3 groups, excepting vascular access time. ED dwell time contributed the most to the difference in median reperfusion time within each group. Time of presentation, comorbidities, and sex were each significantly associated with delayed reperfusion. Within the EHS-direct group, prolonged reperfusion and ED dwell times were significantly associated with increased mortality, major bleeding, and cardiogenic shock. Conclusion Ongoing efforts to identify and reduce ED dwell time and other systemic pPCI delays may improve STEMI outcomes, including mortality.

Abstract
Background We aimed to determine the change in treatment strategies and times to treatment over the first 5 years of the Mission: Lifeline program. Methods and Results We assessed pre‐ and in‐hospital care and outcomes from 2008 to 2012 for patients with ST‐segment–elevation myocardial infarction at US hospitals, using data from the National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry—Get With The Guidelines Registry. In‐hospital adjusted mortality was calculated including and excluding cardiac arrest as a reason for primary percutaneous coronary intervention delay. A total of 147 466 patients from 485 hospitals were analyzed. There was a decrease in the proportion of eligible patients not treated with reperfusion (6.2% versus 3.3%) and treated with fibrinolytic therapy (13.4% versus 7.0%). Median time from symptom onset to first medical contact was unchanged (≈50 minutes). Use of prehospital ECGs increased (45% versus 71%). All major reperfusion times improved: median first medical contact‐to‐device for emergency medical systems transport to percutaneous coronary intervention–capable hospitals (93 to 84 minutes), first door‐to‐device for transfers for primary percutaneous coronary intervention (130 to 112 minutes), and door‐in–door‐out at non–percutaneous coronary intervention–capable hospitals (76 to 62 minutes) (all P<0.001 over 5 years). Rates of cardiogenic shock and cardiac arrest, and overall in‐hospital mortality increased (5.7% to 6.3%). Adjusted mortality excluding patients with known cardiac arrest decreased by 14% at 3 years and 25% at 5 years (P<0.001). Conclusions Quality of care for patients with ST‐segment–elevation myocardial infarction improved over time in Mission: Lifeline, including increased use of reperfusion therapy and faster times‐to‐treatment. In‐hospital mortality improved for patients without cardiac arrest but did not appear to improve overall as the number of these high‐risk patients increased.

Int J Qual Health Care 2019; 31:598-605. [PMID: 30380059 DOI: 10.1093/intqhc/mzy220] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 05/25/2018] [Accepted: 10/15/2018] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVE To measure competition amongst providers and to examine whether a correlation exists with hospitals mortality for congestive heart failure (CHF), acute myocardial infarction (AMI), isolated-coronary artery bypass graft (CABG) or valve surgery. DESIGN Cross-sectional study based on publically available data from the National Outcome Evaluation Program (Edition 2016) of the Italian Agency for Regional Health Services. SETTING AND PARTICIPANTS Patients discharged during 2015 for CHF or AMI, and between 2014 and 2015 for cardiac surgery (respectively, from 662, 395 and 91 hospitals). MAIN OUTCOME MEASURES Risk-adjusted mortality rates at 30 days and measures of hospital competition for areas centred on hospital' location (fixed-radius 50-150 km, variable-radius to capture 10-30 hospitals and 6-10% of national volume). Competition was estimated as number of providers and Herfindahl-Hirschman Index (HHI). RESULTS Indicators of competitions varied by condition and were sensitive to method used for the area definition. Hospital mortality after AMI and valve surgery increased with competition in areas identified by the variable-radius method (higher rates for a greater number of hospitals or lower HHIs). In area with fixed radius of 100-150 km, competition reduced mortality after CABG procedures (lower rates for a greater number of hospitals or smaller HHIs). Neither the number of hospitals nor HHI correlated with outcomes in CHF. CONCLUSIONS The measures of hospital competition changed according to definition of local market and results in mortality correlations varied among conditions. Understanding the relationship between hospital competition and outcomes is important to identify strategies to improve quality of care.

Abstract
Background Kidney transplant (KT) patients presenting with cardiovascular (CVD) events are being managed increasingly in non-transplant facilities. We aimed to identify drivers of mortality and costs, including transplant hospital status. Methods Data from the 2009–2011 Nationwide Inpatient Sample, the American Hospital Association, and Hospital Compare were used to evaluate post-KT patients hospitalized for MI, CHF, stroke, cardiac arrest, dysrhythmia, and malignant hypertension. We used generalized estimating equations to identify clinical, structural, and process factors associated with risk-adjusted mortality and high cost hospitalization (HCH). Results Data on 7803 admissions were abstracted from 275 hospitals. Transplant hospitals had lower crude mortality (3.0% vs. 3.8%, p = 0.06), and higher un-adjusted total episodic costs (Median $33,271 vs. $28,022, p < 0.0001). After risk-adjusting for clinical, structural, and process factors, mortality predictors included: age, CVD burden, CV destination hospital, diagnostic cardiac catheterization without intervention (all, p < 0.001). Female sex, race, documented co-morbidities, and hospital teaching status were protective (all, p < 0.05). Transplant and non-transplant hospitals had similar risk-adjusted mortality. HCH was associated with: age, CVD burden, CV procedures, and staffing patterns. Hospitalizations at transplant facilities had 37% lower risk-adjusted odds of HCH. Cardiovascular process measures were not associated with adverse outcomes. Conclusion KT patients presenting with CVD events had similar risk-adjusted mortality at transplant and non-transplant hospitals, but high cost care was less likely in transplant hospitals. Transplant hospitals may provide better value in cardiovascular care for transplant patients. These data have significant implications for patients, transplant and non-transplant providers, and payers.

Abstract
AIMS AND OBJECTIVES To establish and report cross-sectional data of reperfusion times for emergency primary percutaneous coronary interventions (PPCI) and to examine factors associated with times to reperfusion. BACKGROUND Rapid coronary reperfusion can salvage myocardial tissue, preserve left ventricular function and reduce mortality. PPCI is the gold standard of management. Researchers have reported on international median reperfusion times, but this is the first Irish study to do so. METHODS This observational, prospective, cross-sectional study included patients diagnosed with ST-segment elevation myocardial infarction (STEMI) and admitted for emergency PPCI. Descriptive and inferential statistics were used. The study was ethically approved. We adopted the STROBE guidelines. RESULTS All patients (N = 133) who met the inclusion criteria were included initially. Of these, 105 (79%) were diagnosed with STEMI and received emergency PPCI. The majority of STEMIs were diagnosed by paramedics and most (67%) were reperfused within 120 min, with a median time of 96 min. The results suggested that younger patients achieved timelier PPCI and source of referral was also significant in that more of those transferred directly to the coronary catheterisation laboratory achieved reperfusion within 120 min, compared with those who presented to the emergency department. CONCLUSION A timely reperfusion service is achieved for the majority. Attention is needed in respect of the ageing and those admitted directly to the emergency departments with STEMI. RELEVANCE TO CLINICAL PRACTICE Further international research is recommended to compare current reperfusion times against guidelines and to identify areas for improvement. Clinicians should be mindful of the importance of rapid reperfusion and the implications of its delay for patients with STEMI. Those presenting to emergency departments with chest pain should be prioritised.

Abstract
Zusammenfassung
Hintergrund Studien haben beschrieben, dass höhere Herzinfarktfallzahlen des behandelnden Krankenhauses mit besseren Behandlungsergebnissen assoziiert sind. Vor diesem Hintergrund wird die Entwicklung der akutstationären Herzinfarktversorgung sowie der Mengen-Ergebnisbeziehung im Zeitverlauf analysiert. Ziel der Arbeit ist, die Entwicklungen zu bewerten und Anhaltspunkte für eine Verbesserung der Herzinfarktversorgung in Deutschland abzuleiten.
Methode Anhand der deutschlandweiten Krankenhausabrechnungsdaten (DRG-Statistik) von 2005 bis 2015 wurden Patienten mit akutem Herzinfarkt im erstbehandelnden Krankenhaus identifiziert und anhand der jährlichen Herzinfarktfallzahl des behandelnden Krankenhauses in fallzahlgleiche Quintile eingeteilt.
Ergebnisse Im Beobachtungszeitraum zeigte sich ein zunehmender Anteil interventionell versorgter Herzinfarktpatienten. Die Krankenhaussterblichkeit im erstbehandelnden Krankenhaus ging insgesamt von 12,1 auf 8,7% zurück. In allen Jahren wurde in den höheren Fallzahlquintilen eine geringere Sterblichkeit im Vergleich zum unteren Fallzahlquintil beobachtet. Im Jahr 2015 zeigte sich im Vergleich zur Behandlung in Krankenhäusern mit sehr geringer Fallzahl ein um 20% reduziertes Sterberisiko (adjustiertes OR jeweils 0,8 [95% KI 0,7–0,9]) in Krankenhäusern mit mittlerer, hoher oder sehr hoher Fallzahl. Mehr als 40% der Krankenhäuser mit sehr geringer Fallzahl waren in städtischen Regionen lokalisiert.
Schlussfolgerung Eine gezieltere Steuerung von Patienten mit Herzinfarktsymptomen in Krankenhäuser mit hohen Herzinfarktfallzahlen könnte die Versorgung weiter verbessern. Eine solche Versorgungssteuerung ist sowohl aus Gründen der medizinischen Qualität als auch der Wirtschaftlichkeit insbesondere in städtischen Regionen erforderlich.

Abstract
Background Few data exist on regional systems of care for the treatment of ST‐segment–elevation myocardial infarction (STEMI) in developing countries. Our objective was to describe temporal trends in 30‐day mortality and identify predictors of mortality among STEMI patients enrolled in a prospective registry in Brazil. Methods and Results From January 2011 to June 2013, 520 patients who received initial STEMI care at 23 nonspecialized public health units or hospitals, some of whom were transferred to a public cardiology referral center, were identified through a regional STEMI network supported by telemedicine and the local prehospital emergency medical service. We stratified patients into five 6‐month periods based on presentation date. Mean age (±SD) of patients was 62.0 (±12.2) years, and 55.6% were men. The mean Global Registry of Acute Coronary Events (GRACE) score was 145 (±34). Overall mortality at 30 days was 15.0%. Use of dual antiplatelet therapy and statins increased significantly from baseline (January 2011) to period 5 (June 2013): 61.8% to 93.6% (P<0.001) and 60.4% to 79.7% (P<0.001), respectively. Rates of primary reperfusion also increased (29.1%–53.8%; P<0.001), and more patients were transferred to the referral center (44.7%–76.3%; P=0.001). Thirty‐day mortality rates decreased from 19.8% to 5.1% (P<0.001). In multivariable analysis, factors independently associated with 30‐day mortality were higher GRACE score, history of previous stroke, lack of transfer to the referral center, and lack of use of optimized medical therapy. Conclusions Implementation of a regional STEMI system was associated with lower mortality and higher use of evidence‐based therapies.

Abstract
BACKGROUND We evaluated the first-medical-contact-to-balloon (FMC2B) time after implementation of a "Call 911" protocol for ST-segment-elevation myocardial infarction (STEMI) interfacility transfers in a regional system. METHODS AND RESULTS This is a retrospective cohort study of consecutive patients with STEMI requiring interfacility transfer from a STEMI referring hospital, to one of 35 percutaneous coronary intervention-capable STEMI receiving centers (SRCs). The Call 911 protocol allows the referring physician to activate 911 to transport a patient with STEMI to the nearest SRC for primary percutaneous coronary intervention. Patients with interfacility transfers were identified over a 4-year period (2011-2014) from a registry to which SRCs report treatment and outcomes for all patients with STEMI transported via 911. The primary outcomes were median FMC2B time and the proportion of patients achieving the 120-minute goal. FMC2B for primary 911 transports were calculated to serve as a system reference. There were 2471 patients with STEMI transferred to SRCs by 911 transport during the study period, of whom 1942 (79%) had emergent coronary angiography and 1410 (73%) received percutaneous coronary intervention. The median age was 61 years (interquartile range [IQR] 52-71) and 73% were men. The median FMC2B time was 111 minutes (IQR 88-153) with 56% of patients meeting the 120-minute goal. The median STEMI referring hospital door-in-door-out time was 53 minutes (IQR 37-89), emergency medical services transport time was 9 minutes (IQR 7-12), and SRC door-to-balloon time was 44 minutes (IQR 32-60). For primary 911 patients (N=4827), the median FMC2B time was 81 minutes (IQR 67-97). CONCLUSIONS Using a Call 911 protocol in this regional cardiac care system, patients with STEMI requiring interfacility transfers had a median FMC2B time of 111 minutes, with 56% meeting the 120-minute goal.

Abstract
BACKGROUND The Mission: Lifeline STEMI Systems Accelerator program, implemented in 16 US metropolitan regions, resulted in more patients receiving timely reperfusion. We assessed whether implementing key care processes was associated with system performance improvement. METHODS AND RESULTS Hospitals (n=167 with 23 498 ST-segment-elevation myocardial infarction patients) were surveyed before (March 2012) and after (July 2014) program intervention. Data were merged with patient-level clinical data over the same period. For reperfusion, hospitals were grouped by whether a specific process of care was implemented, preexisting, or never implemented. Uptake of 4 key care processes increased after intervention: prehospital catheterization laboratory activation (62%-91%; P<0.001), single call transfer protocol from an outside facility (45%-70%; P<0.001), and emergency department bypass for emergency medical services direct presenters (48%-59%; P=0.002) and transfers (56%-79%; P=0.001). There were significant differences in median first medical contact-to-device times among groups implementing prehospital activation (88 minutes implementers versus 89 minutes preexisting versus 98 minutes nonimplementers; P<0.001 for comparisons). Similarly, patients treated at hospitals implementing single call transfer protocols had shorter median first medical contact-to-device times (112 versus 128 versus 152 minutes; P<0.001). Emergency department bypass was also associated with shorter median first medical contact-to-device times for emergency medical services direct presenters (84 versus 88 versus 94 minutes; P<0.001) and transfers (123 versus 127 versus 167 minutes; P<0.001). CONCLUSIONS The Accelerator program increased uptake of key care processes, which were associated with improved system performance. These findings support efforts to implement regional ST-segment-elevation myocardial infarction networks focused on prehospital catheterization laboratory activation, single call transfer protocols, and emergency department bypass.

Abstract
BACKGROUND The American Heart Association Mission: Lifeline STEMI (ST-segment-elevation myocardial infarction) Systems Accelerator program, conducted in 16 regions across the United States to improve key care processes, resulted in more patients being treated within national guideline goals (time from first medical contact to device: <90 minutes for direct presenters to hospitals capable of performing percutaneous coronary intervention; <120 minutes for transfers). We examined whether the effort reduced reperfusion disparities in the proportions of female versus male and black versus white patients. METHODS AND RESULTS In total, 23 809 patients (29.3% female, 82.3% white, and 10.7% black) presented with acute STEMI between July 2012 and March 2014. Change in the proportion of patients treated within guideline goals was compared between sex and race subgroups for patients presenting directly to hospitals capable of performing percutaneous coronary intervention (n=18 267) and patients requiring transfer (n=5542). The intervention was associated with an increase in the proportion of men treated within guideline goals that presented directly (58.7-62.1%, P=0.01) or were transferred (43.3-50.7%, P<0.01). An increase was also seen among white patients who presented directly (57.7-59.9%, P=0.02) or were transferred (43.9-48.8%, P<0.01). There was no change in the proportion of female or black patients treated within guideline goals, including both those presenting directly and transferred. CONCLUSION The STEMI Systems Accelerator project was associated with an increase in the proportion of patients meeting guideline reperfusion targets for male and white patients but not for female or black patients. Efforts to organize systems of STEMI care should implement additional processes targeting barriers to timely reperfusion among female and black patients.

Abstract
BACKGROUND Recent data from the National Cardiovascular Data Registry indicate that women with ST-segment-elevation myocardial infarction (STEMI) continue to have higher mortality and reported delays in treatment compared with men. We aimed to determine whether the sex difference in mortality exists when treatment disparities are reduced. METHODS Using a prospective regional percutaneous coronary intervention (PCI)-based STEMI system database with a standardized STEMI protocol, we evaluated baseline characteristics, treatment, and clinical outcomes of STEMI patients stratified by sex. RESULTS From March 2003 to January 2016, 4,918 consecutive STEMI patients presented to the Minneapolis Heart Institute at Abbott Northwestern Hospital regional STEMI system including 1,416 (28.8%) women. Compared with men, women were older (68.4 vs 60.9 years) with higher rates of hypertension (66.7% vs 55.7%), diabetes (21.7% vs 17.4%), and cardiogenic shock (11.5% vs 8.0%) (all P < .001). Pre-revascularization medications and PCI were performed with same frequencies, but women were less likely to receive statin or antiplatelet therapy at discharge. After age adjustment, women had similar in-hospital mortality to men (5.1% vs 4.8%, P = .60) despite slightly longer door-to-balloon time (95 vs 92 minutes, P = .004). Five-year follow-up confirmed absence of a sex disparity in age-adjusted survival post-STEMI. CONCLUSIONS Previously reported treatment disparities between men and women are diminished in a regional PCI-based STEMI system using a standardized STEMI protocol. No sex differences in short-term or long-term age-adjusted mortality are present in this registry despite some treatment disparities. These results suggest that STEMI health care disparities and mortality in women can be improved using STEMI protocols and systems.

Abstract
AIMS The STREAM study randomly assigned ST-elevation myocardial infarction (STEMI) patients to receive a pharmacoinvasive versus primary percutaneous coronary intervention reperfusion strategy. We assessed whether there was an association between outcomes based on randomisation at a community hospital versus a prehospital location. METHODS/RESULTS Community hospital patients (358/1866 (19.2%)) were compared to prehospital patients and their outcomes categorised into pharmacoinvasive according to their treatment assignment. Compared to prehospital patients, community hospital patients had more diabetes (17.8% vs. 11.5%, P=0.001), higher Killip Class >1 (9.4% vs. 5.0%, P=0.002) and thrombolysis in myocardial infarction risk scores ⩾5 (18.2% vs. 12.4%, P=0.005). The 30-day primary endpoint (death, shock, congestive heart failure and re-infarction) for community hospital patients was 14.9% versus 13.2% for prehospital patients ( P=0.403). Community hospital pharmacoinvasive patients tended to receive less rescue (35.1% vs. 42.8%, P=0.062); when deployed their rescue was delayed 43 minutes. Community hospital patients undergoing primary percutaneous coronary intervention experienced a delay of 31 minutes versus prehospital patients. Pharmacoinvasive patients receiving scheduled angiography from a community hospital and prehospital patients had comparable times to angiography (17.7 vs. 18.7 hours) and low event rates (6.2% vs. 8.0%). Although the interaction between randomisation location and treatment received on the primary endpoint was not significant ( Pinteraction=0.065) those pharmacoinvasive patients requiring rescue from community hospitals had worse outcomes than prehospital rescue patients (odds ratio 2.28, 95% confidence interval 1.16-4.49). CONCLUSION Within STREAM, STEMI patients randomly assigned at community hospitals had a higher baseline risk but similar outcomes compared to those studied prehospital patients irrespective of successful pharmacoinvasive therapy or primary percutaneous coronary intervention. However, worse outcomes in the pharmacoinvasive patients requiring rescue in community hospitals emphasises their need for immediate transfer to a percutaneous coronary intervention-capable hospital.

Abstract
Current guidelines recommend that communities create and maintain a regional system of ST-segment elevation myocardial infarction (STEMI) care that includes assessment and continuous quality improvement of emergency medical services and hospital-based activities. Availability and timely access is a challenge in many areas of the United States. This article reviews clinical trial data supporting the use of primary percutaneous coronary intervention as the optimal reperfusion strategy, and fibrinolysis as an option when this is not possible. It then describes the outcomes and benefits of implementing regional systems of STEMI care, and discusses ongoing challenges for STEMI system implementation, including inadequate data collection and feedback, and hospital and physician competition.

Abstract
Background: Helicopter emergency medical services (HEMS) and ground EMS (GEMS) are both integral parts of out-of-hospital transport systems for patients with ST-elevation myocardial infarction (STEMI) undergoing emergency transport for primary percutaneous coronary intervention (PPCI). There are firm data linking time savings for PPCI transports with improved outcome. A previous pilot analysis generated preliminary estimates for potential HEMS-associated time savings for PPCI transports. Methods: This non-interventional multicenter study conducted over the period 2012–2014 at six centers in the USA and in the State of Qatar assessed a consecutive series of HEMS transports for PPCI; at one center consecutive GEMS transports of at least 15 miles were also assessed if they came from sites that also used HEMS (dual-mode referring hospitals). The study assessed time from ground or air EMS dispatch to transport a patient to a cardiac center, through to the time of patient arrival at the receiving cardiac unit, to determine proportions of patients arriving within accepted 90- and 120-minute time windows for PPCI. Actual times were compared to “route-mapping” GEMS times generated using geographical information software. HEMS' potential time savings were calculated using program-specific aircraft characteristics, and the potential time savings for HEMS was translated into estimated mortality benefit. Results: The study included 257 HEMS and 27 GEMS cases. HEMS cases had a high rate of overall transport time (from dispatch to receiving cardiac unit arrival) that fell within the predefined windows of 90 minutes (67.7% of HEMS cases) and 120 minutes (91.1% of HEMS cases). As compared to the calculated GEMS times, HEMS was estimated to accrue a median time saving of 32 minutes (interquartile range, 17–46). The number needed to transport for HEMS to get one additional case to PPCI within 90 minutes was 3. In the varied contexts of this multicenter study, the number of lives saved by HEMS, solely through time savings, was calculated as 1.34 per 100 HEMS PPCI transports. Conclusions: In this multicenter study, HEMS PPCI transport was found to be appropriate as defined by meeting predefined time windows. The overall estimate for lives saved through time savings alone was consistent with previous pilot data and was also generally consistent with favorable cost-effectiveness. Further research is necessary to confirm these findings, but judicious HEMS deployment for PPCI transports is justified by these data.

Abstract
OBJECTIVES This study sought to assess the influence of direct admission versus transfer via regional hospital to a percutaneous coronary intervention (PCI) center on time delays and 12-month mortality in ST-segment elevation myocardial infarction (STEMI) patients from a real-life perspective. BACKGROUND Reduction of delays to reperfusion is crucial in a STEMI system of care. However, it is still debated whether direct admission to a PCI center is superior to interhospital transfer in terms of long-term prognosis. The authors hypothesized that compared with interhospital transfer, direct admission shortens the total ischemic time, limits the loss of left ventricular systolic function, and finally, reduces 12-month mortality. METHODS Prospective nationwide registry data of STEMI patients admitted to PCI centers within 12 h of symptom onset and treated with PCI between 2006 and 2013 were analyzed. Patients admitted directly were compared with patients transferred to a PCI center via a regional non-PCI-capable facility in terms of time delays, left ventricular ejection fraction (LVEF), and 12-month mortality. Data were adjusted using propensity-matched and multivariate Cox analyses. RESULTS Of the 70,093 patients eligible for analysis, 39,144 (56%) were admitted directly to a PCI center. Direct admission was associated with a shorter median symptoms-to-admission time (by 44 min; p < 0.001) and total ischemic time (228 vs. 270 min; p < 0.001), higher LVEF (47.5% vs. 46.3%; p < 0.001), and lower propensity-matched 12-month mortality (9.6% vs. 10.4%; p < 0.001). In propensity-matched multivariate Cox analysis, direct admission (hazard ratio [HR]: 1.06, 95% confidence interval [CI]: 1.01 to 1.11) and shorter symptoms-to-admission time (HR: 1.03; 95% CI: 1.01 to 1.06) were significant predictors of lower 12-month mortality. CONCLUSIONS In a large, community-based cohort of patients with STEMI treated by PCI, direct admission to a primary PCI center was associated with lower 12-month mortality and should be preferred to transfer via a regional non-PCI-capable facility.

Abstract
ST-elevation myocardial infarction (STEMI), which constitutes nearly 25-40 % of current acute myocardial infarction (AMI) cases, is a medical emergency that requires prompt recognition and treatment. Since the 2013 STEMI practice guidelines, a wealth of additional data that may further advance optimal STEMI practices has emerged. These data highlight the importance of improving patient treatment and transport algorithms for STEMI from non-primary percutaneous coronary intervention (PCI) centers. In addition, a focus on the reduction of total pain-to-balloon (P2B) times rather than simply door-to-balloon (D2B) times may further improve outcomes after primary PCI for STEMI. The early administration of newer oral P2Y12 inhibitors, including crushed forms of these agents for faster absorption, represents another treatment advancement. Recent data also suggest avoiding concurrent morphine use due to interactions with P2Y12 inhibitors. Furthermore, new technological advancements and investigational therapies, including Bioresorbable Vascular Scaffolds and the use of pre-intervention intravenous microbubbles with transthoracic ultrasound, hold promise to play a useful role in future STEMI care. Despite these advancements, the prompt recognition of STEMI, at both the patient and health care system level, remains the cornerstone of optimal treatment.

Abstract
BACKGROUND Up to 50% of patients fail to meet ST-segment-elevation myocardial infarction (STEMI) guideline goals recommending a first medical contact-to-device time of <90 minutes for patients directly presenting to percutaneous coronary intervention-capable hospitals and <120 minutes for transferred patients. We sought to increase the proportion of patients treated within guideline goals by organizing coordinated regional reperfusion plans. METHODS We established leadership teams, coordinated protocols, and provided regular feedback for 484 hospitals and 1253 emergency medical services (EMS) agencies in 16 regions across the United States. RESULTS Between July 2012 and December 2013, 23 809 patients presented with acute STEMI (direct to percutaneous coronary intervention hospital: 11 765 EMS transported and 6502 self-transported; 5542 transferred). EMS-transported patients differed from self-transported patients in symptom onset to first medical contact time (median, 47 versus 114 minutes), incidence of cardiac arrest (10% versus 3%), shock on admission (11% versus 3%), and in-hospital mortality (8% versus 3%; P<0.001 for all comparisons). There was a significant increase in the proportion of patients meeting guideline goals of first medical contact-to-device time, including those directly presenting via EMS (50% to 55%; P<0.001) and transferred patients (44%-48%; P=0.002). Despite regional variability, the greatest gains occurred among patients in the 5 most improved regions, increasing from 45% to 57% (direct EMS; P<0.001) and 38% to 50% (transfers; P<0.001). CONCLUSIONS This Mission: Lifeline STEMI Systems Accelerator demonstration project represents the largest national effort to organize regional STEMI care. By focusing on first medical contact-to-device time, coordinated treatment protocols, and regional data collection and reporting, we were able to increase significantly the proportion of patients treated within guideline goals.

Abstract
Heart disease remains the leading cause of death in the USA. Overall, heart disease accounts for about 1 in 4 deaths with coronary heart disease (CHD) being responsible for over 370,000 deaths per year. It has frequently and repeatedly been shown that some minority groups in the USA have higher rates of traditional CHD risk factors, different rates of treatment with revascularization procedures, and excess morbidity and mortality from CHD when compared to the non-Hispanic white population. Numerous investigations have been made into the causes of these disparities. This review aims to highlight the recent literature which examines CHD in ethnic minorities and future directions in research and care.

Abstract
Background Little is known about Emergency Medical Services (EMS) use and pre-hospital triage of patients with acute ST-elevation myocardial infarction (STEMI) in Arabian Gulf countries. Methods Clinical arrival and acute care within 24 h of STEMI symptom onset were compared between patients transferred by EMS (Red Crescent and Inter-Hospital) and those transferred by non-EMS means. Data were retrieved from a prospective registry of 36 hospitals in 6 Arabian Gulf countries, from January 2014 to January 2015. Results We enrolled 2,928 patients; mean age, 52.7 (SD ±11.8) years; 90% men; and 61.7% non-Arabian Gulf citizens. Only 753 patients (25.7%) used EMS; which was mostly via Inter-Hospital EMS (22%) rather than direct transfer from the scene to the hospital by the Red Crescent (3.7%). Compared to the non-EMS group, the EMS group was more likely to arrive initially at a primary or secondary health care facility; thus, they had longer median symptom-onset-to-emergency department arrival times (218 vs. 158 min; p˂.001); they were more likely to receive primary percutaneous coronary interventions (62% vs. 40.5%, p = 0.02); they had shorter door-to-needle times (38 vs. 42 min; p = .04); and shorter door-to-balloon times (47 vs. 83 min; p˂.001). High EMS use was independently predicted mostly by primary/secondary school educational levels and low or moderate socioeconomic status. Low EMS use was predicted by a history of angina and history of percutaneous coronary intervention. The groups had similar in-hospital deaths and outcomes. Conclusion Most acute STEMI patients in the Arabian Gulf region did not use EMS services. Improving Red Crescent infrastructure, establishing integrated STEMI networks, and launching educational public campaigns are top health care system priorities.

Abstract
BACKGROUND Interhospital transfer delays for ST-elevation myocardial infarction (STEMI) patients requiring primary percutaneous coronary intervention (PCI) may be shortened by improved regional care systems. We evaluated the transfer process and first door-to-balloon (D1toB) time in STEMI patients who underwent interhospital transfer for primary PCI. METHODS AND RESULTS We evaluated the D1toB time in 1837 patients who underwent interhospital transfer for primary PCI from the Cardiovascular Disease Surveillance program in Korea. Only 29.3% of patients had a D1toB time less than 120 minutes, as recommended by the American College of Cardiology Foundation/American Heart Association guidelines for the management of STEMI. After adjusting for potential confounders, chest pain at presentation (adjusted odds ratio [AOR], 2.06; 95% confidence interval [CI], 1.18-3.83), transfer to a PCI center with an annual PCI volume greater than 200 (AOR, 1.35; 95% CI, 1.04-1.74), and higher urbanization level (AOR, 2.01 [95% CI, 1.40-2.91], for urban areas; AOR, 3.70 [95% CI, 2.59-3.83], for metropolitan areas) showed beneficial effects on reducing the D1toB time. The median length of stay in the referring hospital (D1LOS) and interhospital transport time were 50 (interquartile range [IQR], 30-100) minutes and 32 (IQR, 20-51) minutes, respectively. The median time interval from the door of the receiving hospital to balloon insertion was 55 (IQR, 40-79) minutes. CONCLUSIONS Patients with STEMI undergoing interhospital transfer did not receive definite care within the recommended therapeutic time window. Delays in the transfer process (length of stay in the referring hospital and interhospital transport time) were major contributors to the delay in the D1toB time.
