Abstract
BACKGROUND Current guidelines emphasize the diagnostic value of non-cardiac or possibly cardiac chest pain. The goal of this analysis was to determine whether German chest pain units (CPUs) adequately address conditions with "atypical" chest pain in existing diagnostic structures. METHOD A total of 11,734 patients from the German CPU registry were included. The analyses included mode of admission, critical time intervals, diagnostic steps, and differential diagnoses. RESULTS Patients with unspecified chest pain were younger, more often female, were less likely to have classic cardiovascular risk factors and tended to present more often as self-referrals. Patients with acute coronary syndrome (ACS) mostly had prehospital medical contact. Overall, there was no difference between these two groups regarding the time from the onset of first symptoms to arrival at the CPU. In the CPU, the usual basic diagnostic measures were performed irrespective of ACS as the primary working diagnosis. In the non-ACS group, further ischemia-specific diagnostics were rarely performed. Extra-cardiac differential diagnoses were not specified. CONCLUSION The establishment of broader awareness programs and opening CPUs for low-threshold evaluation of self-referring patients should be discussed. Regarding the rigid focus on the clarification of cardiac causes of chest pain, a stronger interdisciplinary approach should be promoted.

Prevalence and Predictors of Emergency Medical Service Use in Patients Undergoing Primary Percutaneous Coronary Intervention for ST-Elevation Myocardial Infarction. Heart Lung Circ 2024:S1443-9506(24)00129-X. [PMID: 38570261 DOI: 10.1016/j.hlc.2024.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 02/08/2024] [Accepted: 02/15/2024] [Indexed: 04/05/2024]
Abstract
AIM We aim to describe prevalence of Emergency Medical Service (EMS) use, investigate factors predictive of EMS use, and determine if EMS use predicts treatment delay and mortality in our ST-elevation myocardial infarction (STEMI) cohort. METHOD We prospectively collected data on 5,602 patients presenting with STEMI for primary percutaneous coronary intervention (PCI) transported to PCI-capable hospitals in Victoria, Australia, from 2013-2018 who were entered into the Victorian Cardiac Outcomes Registry (VCOR). We linked this dataset to the Ambulance Victoria and National Death Index (NDI) datasets. We excluded late presentation, thrombolysed, and in-hospital STEMI, as well as patients presenting with cardiogenic shock and out-of-hospital cardiac arrest. RESULTS In total, 74% of patients undergoing primary PCI for STEMI used EMS. Older age, female gender, higher socioeconomic status, and a history of prior ischaemic heart disease were independent predictors of using EMS. EMS use was associated with shorter adjusted door-to-balloon (53 vs 72 minutes, p<0.001) and symptom-to-balloon (183 vs 212 minutes, p<0.001) times. Mode of transport was not predictive of 30-day or 12-month mortality. CONCLUSIONS EMS use in Victoria is relatively high compared with internationally reported data. EMS use reduces treatment delay. Predictors of EMS use in our cohort are consistent with those prevalent in prior literature. Understanding the patients who are less likely to use EMS might inform more targeted education campaigns in the future.

Abstract
BACKGROUND How quickly percutaneous coronary intervention is performed in patients with ST-elevation myocardial infarction (STEMI) is a quality measure, reported as door-to-balloon (D2B) time. OBJECTIVES To explore factors affecting STEMI performance in six hospitals in one healthcare system. METHODS This was a retrospective chart review of clinical features and D2B times. Predictors for D2B times were identified using multivariate linear regression. RESULTS The median D2B time for all six hospitals was 63 minutes and all hospitals surpassed the minimal recommended percentage of patients achieving D2B time ≤90 minutes (87.8%vs75%,p<0.001). Patient confounders adversely affect D2B times (+21.5 minutes, p<0.001). Field ECG/activation with emergency department (ED) transport (-22.0 minutes) or direct cardiac catheterization laboratory (CCL) transport (-27.3 minutes) was superior to ED ECG/activation (p<0.001). CONCLUSION Field ECG/STEMI activation significantly shortened D2B time. To improve D2B time, hospital and Emergency Medical Service collaboration should be advocated to increase field activation and direct patient transportation to CCL.

Abstract
Objective This study is to document the clinical characteristics and improvement in management of acute myocardial infarction (AMI) in Chinese population. Results This study included 64,654 patients (23,805 patients in 2011, 40,849 patients in 2013), of which STEMI and NSTEMI account for 85.09% and 14.91%, respectively. From 2011 to 2013, significant improvement has been achieved in the recanalization rate of PCI (96.01% vs. 98.63%, P < 0.001) and in-hospital deaths (4.52% vs. 3.55%, P = 0.038). Although the time of door-to-balloon and the duration of PCI were satisfactorily controlled within 90min and 60min, respectively, the onset-to-FMC time (≈3.5h) and door-to-thrombolysis time (≈1.1h) limited the efficiency of management. The total cost of medical care showed no increase from 2011 to 2013, but the patient's paid Portion decreased from 20.33% to 13.96%. Materials and Methods The AMI patients admitted in the general hospitals in 2011 and 2013 were retrospectively analyzed according to the data reported to the Single Disease Quality Control Information Systemissued by Chinese Hospital Association. Conclusion Compared to the Western countries, STEMI accounted for a larger portion of AMI, and the AMI management in China basically meets the standards of the quality control of guidelines. With improvement of management, there was no increase in the total medical cost, while the patient's paid portion was actually reduced. In future, improvement of transportation strategy and the public medical education are recommended to shorten the onset-to-FMC time to further improve the outcome of AMI patients.

Abstract
Reperfusion therapy decreases myocardium damage during an acute coronary event and consequently mortality. However, there are unmet needs in the treatment of acute myocardial infarction, consequently mortality and heart failure continue to occur in about 10% and 20% of cases, respectively. Different strategies could improve reperfusion. These strategies, like generation of warning sign recognition and being initially assisted and transferred by an emergency service, could reduce the time to reperfusion. If the first electrocardiogram is performed en route, it can be transmitted and interpreted in a timely manner by a specialist at the receiving center, bypassing community hospitals without percutaneous coronary intervention capabilities. To administer thrombolytic therapy during transport to the catheterization laboratory could reduce time to reperfusion in cases with expected prolonged transport time to a percutaneous coronary intervention center or to a center without primary percutaneous coronary intervention capabilities with additional expected delay, known as pharmaco-invasive strategy. Myocardial reperfusion is known to produce damage and cell death, which defines the reperfusion injury. Lack of resolution of ST segment is used as a marker of reperfusion failure. In patients without ST segment resolution, mortality triples. It is important to note that, until recently, reperfusion injury and no-reflow were interpreted as a single entity and we should differentiate them as different entities; whereas no-reflow is the failure to obtain tissue flow, reperfusion injury is actually the damage produced by achieving flow. Therefore, treatment of no-reflow is obtained by tissue flow, whereas in reperfusion injury the treatment objective is protection of susceptible myocardium from reperfusion injury. Numerous trials for the treatment of reperfusion injury have been unsuccessful. Newer hypotheses such as “
controlled reperfusion”, in which the interventional cardiologist assumes not only the treatment of the culprit vessel but also the way to reperfuse the myocardium at risk, could reduce reperfusion injury.

Abstract
Aim: To study the effect of dietary supplementation of lecithin and carnitine on growth performance and nutrient digestibility in pigs fed high-fat diet. Materials and Methods: A total of 30 weaned female large white Yorkshire piglets of 2 months of age were selected and randomly divided into three groups allotted to three dietary treatments, T1 - Control ration as per the National Research Council nutrient requirement, T2 - Control ration plus 5% fat, and T3 - T2 plus 0.5% lecithin plus 150 mg/kg carnitine. The total dry matter (DM) intake, fortnightly body weight of each individual animal was recorded. Digestibility trial was conducted toward the end of the experiment to determine the digestibility coefficient of various nutrients. Results: There was a significant improvement (p<0.01) observed for pigs under supplementary groups T2 and T3 than that of control group (T1) with regards to growth parameters studied such as total DM intake, average final body weight and total weight gain whereas among supplementary groups, pigs reared on T3 group had better intake (p<0.01) when compared to T2 group. Statistical analysis of data revealed that no differences were observed (p>0.05) among the three treatments on average daily gain, feed conversion efficiency, and nutrient digestibility during the overall period. Conclusion: It was concluded that the dietary inclusion of animal fat at 5% level or animal fat along with lecithin (0.5%) and carnitine (150 mg/kg) improved the growth performance in pigs than non-supplemented group and from the economic point of view, dietary incorporation of animal fat at 5% would be beneficial for improving growth in pigs without dietary modifiers.

Abstract
The appropriate timing of angiography to facilitate revascularization is essential to optimize outcomes in patents with ST-segment-elevation myocardial infarction and non-ST-segment-elevation acute coronary syndromes. Timely reperfusion of the infarct-related coronary artery in ST-segment-elevation myocardial infarction both with fibrinolysis or percutaneous coronary intervention minimizes myocardial damage, reduces infarct size, and decreases morbidity and mortality. Primary percutaneous coronary intervention is the preferred reperfusion method if it can be performed in a timely manner. Strategies to reduce health system-related delays in reperfusion include regionalization of ST-segment-elevation myocardial infarction care, performing prehospital ECGs, prehospital activation of the catheterization laboratory, bypassing geographically closer nonpercutaneous coronary intervention-capable hospitals, bypassing the percutaneous coronary intervention-capable hospital emergency department, and early and consistent availability of the catheterization laboratory team. With implementation of such strategies, there has been significant improvement in process measures, including door-to-balloon time. However, despite reductions in door-to-balloon times, there has been little change during the past several years in in-hospital mortality, suggesting additional factors including patient-related delays, optimization of tissue-level perfusion, and cardioprotection must be addressed to improve patient outcomes further. Early angiography followed by revascularization when appropriate also reduces rates of death, MI, and recurrent ischemia in patients with non-ST-segment-elevation acute coronary syndromes, with the greatest benefits realized in the highest risk patients. Among patients with non-ST-segment-elevation acute coronary syndromes with multivessel disease, choice of revascularization modality should be made as in stable coronary artery disease, with a goal of complete ischemic revascularization.

Predictors of reperfusion delay in patients with ST elevation myocardial infarction self-transported to the hospital (from the American Heart Association's Mission: Lifeline Program). Am J Cardiol 2014; 113:798-802. [PMID: 24393257 DOI: 10.1016/j.amjcard.2013.11.036] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2013] [Revised: 11/18/2013] [Accepted: 11/18/2013] [Indexed: 11/19/2022]
Abstract
Primary percutaneous coronary intervention for ST elevation myocardial infarction (STEMI) is beneficial if performed in a timely manner. Self-transport patients with STEMI have prolonged treatment times compared with Emergency Medical Services-transported patients. This study evaluated self-transport patients with STEMI undergoing primary percutaneous coronary intervention to identify factors associated with prolonged door-to-balloon (D2B) times. From January 2007 to March 2011, data for 13,379 self-transport patients with STEMI treated at 432 hospitals in the Acute Coronary Treatment Intervention Outcomes Network Registry-Get With The Guidelines Registry were evaluated. Patients with a D2B time >90 minutes were compared with those with D2B time ≤90 minutes. Factors associated with prolonged D2B (>90 minutes) were explored using logistic generalized estimating equations. The median (twenty-fifth, seventy-fifth percentiles) D2B time for the entire cohort was 72 minutes (58, 86), and 19% had a D2B time of >90 minutes. Over the study period, there was a significant increase in the percentage of patients achieving D2B time ≤90 minutes. There were significant baseline differences between patients with D2B time ≤ versus >90 minutes. The main factors associated with prolonged treatment time were off-hour presentation (weekends and 7 p.m. to 7 a.m. weekdays), not obtaining an electrocardiogram within 10 minutes of hospital arrival, previous coronary artery bypass surgery, black race, older age, and female gender. In conclusion, although prolonged delay from arrival to electrocardiographic acquisition is a modifiable factor contributing to prolonged D2B times among self-transport patients with STEMI, additional factors (age, race, and gender) indicate that historic disparities for cardiovascular care still persist in terms of contemporary metrics for STEMI reperfusion.

Abstract
Data are scarce regarding emergency medical service (EMS) usage by patients with acute coronary syndrome (ACS) in the Arabian Gulf region. This 9-month in-hospital prospective ACS registry was conducted in Arabian Gulf countries, with 30-day and 1-year follow-up mortality rates. Of 5184 patients with ACS, 1293 (25%) arrived at the hospital by EMS. The EMS group (vs non-EMS) was more likely to be male, have cardiac arrest on presentation, be current or exsmokers, and have moderate or severe left ventricular dysfunction and ST-segment elevation myocardial infarction (STEMI). The EMS group had higher crude mortality rates during hospitalization and after hospital discharge but not after adjustment for clinical factors and treatments. The EMSs are underused in the Arabian Gulf region. Short- and long-term mortality rates in patients with ACS are similar between those who used and did not use EMS. Quality improvement in the EMS infrastructure and establishment of integrated STEMI networks are urgently needed.

Abstract
This report presents a field-tested approach to the greatest health care problem facing our country, the fact that two-thirds of the deaths from acute myocardial infarction occur before hospital admission. Scores of fundraising appearances for the Missouri Heart Association during the 1950s and 1960s throughout the 1,000,000 population rural/urban Southwest Missouri region gave an ideal setting for teaching the public the early symptoms of heart attack. Audiences were advised that if any of these appeared they should immediately call their doctor or quickly get to the nearest hospital emergency room. These presentations led to a steady increase in hospital admissions. The Missouri Heart Association responded by launching the Early Warning Signs of Heart Attack Public and Professional Education Program in July 1971, incorporating these messages in radio, TV, and newspaper Public Service Announcements. In less than 6 months, analysis of consecutive admissions to the cardiovascular intensive care unit of the base hospital showed that the median time from the onset of symptoms to starting to the hospital was reduced from 4 to 2.2 hours; 64% of those patients called their doctor as their first step in seeking help and 58% went to the hospital by car. This message content was carried through the 1980s and 1990s under other auspices. The methods of the successful Missouri program are contrasted with others that have failed, establishing essential features in designing a nationwide program effective in hastening acute myocardial infarction patient hospital arrival.

Abstract
OBJECTIVE The objectives of this population-based study were to examine the use of emergency medical services (EMS) in greater Worcester, Massachusetts, residents (2000 census = 478,000) hospitalized with acute myocardial infarction (AMI) at all metropolitan Worcester medical centers in four biennial periods between 1997 and 2003. A secondary study aim was to describe the demographic and clinical characteristics of patients with AMI transported to metropolitan Worcester hospitals by EMS, compared with those transported by other means, and their hospital outcomes. METHODS We reviewed the medical records of 3805 patients hospitalized for confirmed AMI at 11 greater Worcester medical centers during 1997, 1999, 2001, and 2003. Information about the use of EMS, patient characteristics, and hospital outcomes was obtained through the review of hospital charts. RESULTS A total of 2693 greater Worcester residents with AMI (70.8%) were transported to area hospitals by ambulance. Patients transported by ambulance were older, were more likely to be women, had a greater prevalence of comorbidities, and had a different symptom profile than patients transported by other means. Patients arriving at greater Worcester hospitals by ambulance were more likely to develop serious clinical complications, including heart failure and cardiogenic shock, and die during hospitalization compared with patients not transported by EMS. CONCLUSIONS Our results suggest that the majority of greater Worcester residents seeking care for AMI are transported by EMS. Patients transported by ambulance differ from patients transported by other means and are more likely to experience adverse hospital outcomes. The reasons why patients use EMS in the setting of AMI need to be further explored and patients' care-seeking behavior enhanced.

Abstract
PURPOSE The aim of the study was to evaluate the rate of ambulance use and the long-term prognosis in acute chest pain in an urban and a rural area and whether there is a difference between an urban and a rural area. PROCEDURES Patients with acute chest pain consecutively admitted to Sahlgrenska University Hospital (a city hospital) and Uddevalla County Hospital between November 1996 and April 1997 were followed up prospectively for 5 years. RESULTS In the city hospital, 688 (36%) of 1907 patients were transported by ambulance as compared with 369 (44%) of 842 patients in the county hospital. The patients transported by ambulance were much older (mean, 71 vs 59 years in both areas), and the comorbidity was more severe among patients transported by ambulance in both areas. In the city hospital, the 5-year mortality was 41.8% among those transported by ambulance and 15.8% among those transported by other means (P < .0001). The corresponding figures for the county hospital were 38.7% and 11.0% with a P value of less than .0001. CONCLUSIONS During the 1990s, patients with acute chest pain who were transported to a hospital by ambulance differed markedly in characteristics and outcome when compared with patients transported by other means. Results did not differ with regard to area.

Abstract
The last decade has seen extraordinary advances in the cardiovascular arena, particularly in the evaluation and management of the patient who has acute coronary syndromes. From bedside markers of myocardial damage to drug-eluting stents, technical advances are proliferating. Efforts in developing an international registry for acute aortic dissection have helped elucidate the acute presentation, management, and prognosis of this uncommon but lethal disease. Finally, the multiple research efforts in coordinating clinical decision-making with serologic markers and advanced imaging for the diagnosis of pulmonary embolism is changing the approach to the patient at risk for thromboembolic disease.

Abstract
Emergency medical services (EMS) providers who administer advanced life support should include diagnostic 12-lead electrocardiography programs as one of their services. Evidence demonstrates that this technology can be readily used by EMS providers to identify patients with ST-segment elevation myocardial infarction (STEMI) before a patient's arrival at a hospital emergency department. Earlier identification of STEMI patients leads to faster artery-opening treatment with fibrinolytic agents, either in the pre-hospital setting or at the hospital. Alternatively, a reperfusion strategy using percutaneous coronary intervention can be facilitated by use of pre-hospital 12-lead electrocardiography (P12ECG). Analysis of the cost of providing this service to the community must include consideration of the demonstrated benefits of more rapid treatment of patients with STEMI and the resulting time savings advantage shown to accompany the use of P12ECG programs.

Abstract
Prehospital intervention has the potential for significantly affecting the outcome of cardiovascular emergencies. The authors examine multiple issues in prehospital care that can streamline and improve cardiac care. Improving access to prehospital care and increasing the use of the emergency medical services (EMS) system can speed interventions to the patients. The use of ECG in the out-of-hospital setting can reduce time to definitive treatment. Issues, such as the use of public access defibrillation and interfacility transports are also discussed.

Abstract
BACKGROUND Studies from overseas indicate that patients with acute myocardial infarction (AMI) symptoms often fail to use the emergency services as recommended, thereby depriving themselves from life-saving treatment in case of cardiac arrest and delaying the time to myocardial reperfusion in the presence of a coronary occlusion. AIMS To compare patients brought in by ambulance to those not brought in by ambulance and to question why some patients do not use the emergency services when presenting to hospital with AMI symptoms. METHODS Prospective interview and follow up of consecutive patients presenting with AMI symptoms to the emergency department of a tertiary hospital in a metropolitan area within a 1-month period. RESULTS Of the 215 patients presenting to the emergency department, 113 (53%) arrived by private transportation. Sixty (53%) of these felt their symptoms did not warrant calling the ambulance, 17 (15%) had first consulted their general practitioner. The private transport group accounted for 28% of documented AMI. CONCLUSIONS A large proportion of patients with AMI symptoms refrain from calling the emergency services because they do not consider themselves critically ill. Education programmes appear to be warranted because more appropriate use of emergency services will save lives.

Abstract
OBJECTIVE To explore the choice of transportation mode to hospital in patients experiencing acute myocardial infarction. METHOD A descriptive survey study at the Coronary Care Unit of one Swedish University Hospital. The study was carried out between July 2000 and March 2001. RESULTS The study population consisted of 114 consecutive patients with acute myocardial infarction. Thirty-two percent stated that they did not know the importance of a short delay when experiencing an acute myocardial infarction. Only 60% called the emergency service number, 112. Patients calling for an ambulance differed from those who did not in several aspects. Medical characteristics associated with ambulance use in a univariate analysis were ST-elevation myocardial infarction and prior history of myocardial infarction. There were no differences regarding gender or age. When looking at the patients' symptom-experience, patients with vertigo or nausea and severe pain chose an ambulance for transport to the hospital. The only significant reasons for not choosing an ambulance were cramping pain and the patient perceiving the symptoms not to be serious. In a multivariate analysis, ST-elevation (OR = 0.30, P = .04), unbearable symptoms (OR = 0.20, P = .03), and nausea (OR = .33, P = .04) appeared as independent predictors of ambulance use and cramping pain (OR = 5.17, P = .01) for not using an ambulance. CONCLUSIONS Patients with acute myocardial infarction view the ambulance as an option for transportation to hospital only if they feel really sick. For that reason, it needs to be made well known to the public that ambulances are not only a mode of transport, but also provide diagnostics and treatment.

Abstract
OBJECTIVE We examined differences in transport times for patients with chest pain who used private transportation compared with patients who used emergency medical services (EMS) to reach definitive medical care. METHODS This was a retrospective cohort study with data used from the Rapid Early Action for Coronary Treatment (REACT) trial conducted in 20 US cities. Elapsed time to care was examined through the use of (1) decision to seek care to initial care (emergency department [ED] arrival versus EMS arrival on scene [n=1209]); (2) decision to ED arrival (for both groups [n=2388]); (3) time to thrombolytic therapy once admitted to the ED (for both groups [n=309]); and (4) decision to seek care to thrombolytic therapy (n=276). Elapsed travel times were ranked within Zip Codes and submitted to a nested analysis of variance model to determine if elapsed times were different between modes of transport. RESULTS Private transportation (35 minutes) resulted in faster ED arrival than using EMS (39 minutes, P =.0014). However, if one considers EMS treatment to be initial care, calling 9-1-1 (6 minutes) resulted in much quicker care than patients using private transportation to the ED (32 minutes, P <.001). Transport by EMS resulted in a shorter elapsed time to thrombolytic administration compared with patients using private transportation when considering ED "door-to-needle" time (32 vs 49 minutes, respectively [P <.001]) or time from decision to seek care until administration of thrombolytic therapy (75 vs 92 minutes, respectively, [P =.042]). CONCLUSIONS Although private transportation results in a faster trip to the ED, quicker care is obtained with the use of EMS.

Abstract
BACKGROUND National practice guidelines strongly recommend activation of the 9-1-1 Emergency Medical Systems (EMS) by patients with symptoms consistent with an acute myocardial infarction (MI). We examined use of the EMS in the United States and ascertained the factors that may influence its use by patients with acute MI. METHODS AND RESULTS From June 1994 to March 1998, the National Registry of Myocardial Infarction 2 enrolled 772 586 patients hospitalized with MI. We excluded those who transferred in, arrived at the hospital >6 hours from symptom onset, or who were in cardiogenic shock. We compared baseline characteristics and initial management for patients who arrived by ambulance versus self-transport. EMS was used in 53.4% of patients with MI, a proportion that did not vary significantly over the 4-year study period. Nonusers of the EMS were on average younger, male, and at relatively lower risk on presentation. In addition, payer status was significantly associated with EMS use. Use of EMS was independently associated with slightly wider use of acute reperfusion therapies and faster time intervals from door to fibrinolytic therapy (12.1 minutes faster, P<0.001) or to urgent PTCA (31.2 minutes faster, P<0.001). CONCLUSIONS Only half of patients with MI were transported to the hospital by ambulance, and these patients had greater and significantly faster receipt of initial reperfusion therapies. Wider use of EMS by patients with suspected MI may offer considerable opportunity for improvement in public health.

Abstract
The objective of this study was to examine Emergency Medical Services (EMS) activation in a cohort of critically ill patients and to evaluate whether factors such as perceived difficulty of access to emergency care, insurance status, and educational level are associated with EMS use. Patients admitted from the emergency department to the intensive care unit (ICU) of an urban county hospital for diagnoses other than acute cardiac conditions or stroke were interviewed about EMS use. Overall EMS use was found to be 52%. Primary reasons for not activating EMS were a belief that symptoms were not serious (36%) or that self-transport was faster (25%). The only factors significantly associated with bypassing EMS were car ownership, lack of health insurance, and self-decision to go to an emergency department. Sixty-eight percent of the sample reported little difficulty in accessing emergency care. In conclusion, because of a belief that symptoms were not serious or self-transport would be faster, nearly half of the critically ill patient sample did not activate EMS. Patient education about warning sign recognition for serious illnesses and about the potential benefits derived from EMS should be improved.

Abstract
STUDY OBJECTIVE To describe the epidemiology and survival from out-of-hospital cardiac arrest. DESIGN Longitudinal follow-up study from the time of paramedic attendance to 12 months later. SETTING Perth, Western Australia (WA), a metropolitan capital city with an adult population of approximately one million people. METHOD The St John Ambulance Australia (WA Ambulance Service Incorporated) cardiac arrest database was linked to the WA hospital morbidity and mortality data using probabilistic matching. INCIDENCE Of 3730 cardiorespiratory arrests in 1996-1999, the age standardised rate of arrests of presumed cardiac origin, where resuscitation was attempted (n=1293) was 32.9 per 100000 person-years and 7.1 per 100000 person-years for bystander-witnessed VF/VT arrests. SURVIVAL Survival to 28 days was 6.8% following all bystander-witnessed cardiac arrests; 10.6% following bystander-witnessed VF/VT arrests and 33% for paramedic-witnessed cardiac arrests. Logistic regression analysis showed an inverse association between ambulance response time interval and survival following all bystander-witnessed cardiac arrests (and VF/VT arrests). ONE YEAR SURVIVAL: 89% of bystander-witnessed cardiac arrest survivors and 92% of paramedic-witnessed cardiac arrests were still alive at 1 year post-arrest. CONCLUSION The trends in occurrence and survival following out-of-hospital cardiac arrest in Perth, WA, are similar to those found elsewhere. There is an opportunity to strengthen the chain of survival by reducing the response time interval and increasing the use of bystander cardiopulmonary resuscitation (CPR). First-responder programs and public access defibrillation will need to be considered in the light of local demographics, location and the epidemiologic features of out-of-hospital cardiac arrest.

Abstract
In Singapore, all public emergency ambulances are equipped with semi-automatic external defibrillators and the crew is trained in their use. This is the first paper from Singapore reporting the survival rate in patients presenting to an urban public hospital with acute coronary syndrome (ACS) who developed out-of-hospital cardiac arrest (OHCA). All consecutive patients who presented to the ED of a public hospital with OHCA or ACS were surveyed from 1 April 1999 to 30 September 1999. There were 392 patients among whom 115 (28.5%) had OHCA. There was no significant difference in age and gender distribution between the OHCA and non-OHCA patients. More than 2/3 of the OHCA patients had no report of chest pain or breathlessness before they collapsed. Forty five (39.1%) of the 115 OHCA patients were noted to have initial rhythms of ventricular tachycardia (VT) or ventricular fibrillation (VF) and received pre-hospital defibrillation. The mean time from collapse to first DC shock was 12.07+/-7.2 min. Twenty (17.4%) of the OHCA patients had return of spontaneous circulation after resuscitation in the ED. Four patients (3.5%), all with an initial rhythm of VF were discharged alive from the hospital. Much remains to be done to reduce the time interval to first DC shock for the OHCA group.
