Abstract
Background Patient delay in presenting to hospital with stroke symptoms remains one of the major barriers to thrombolysis treatment, leading to its suboptimal use internationally. Educational interventions such as mass media campaigns and community initiatives aim to reduce patient delays by promoting the signs and symptoms of a stroke, but no consistent evidence exists to show that such interventions result in appropriate behavioral responses to stroke symptoms. Methods A systematic literature search and narrative synthesis were conducted to examine whether public educational interventions were successful in the reduction of patient delay to hospital presentation with stroke symptoms. Three databases, MEDLINE, CINAHL, and PsycINFO, were searched to identify quantitative studies with measurable behavioral end points, including time to hospital presentation, thrombolysis rates, ambulance use, and emergency department (ED) presentations with stroke. Results Fifteen studies met the inclusion criteria: one randomized controlled trial, two time series analyses, three controlled before and after studies, five uncontrolled before and after studies, two retrospective observational studies, and two prospective observational studies. Studies were heterogeneous in quality; thus, meta-analysis was not feasible. Thirteen studies examined prehospital delay, with ten studies reporting a significant reduction in delay times, with a varied magnitude of effect. Eight studies examined thrombolysis rates, with only three studies reporting a statistically significant increase in thrombolysis administration. Five studies examined ambulance usage, and four reported a statistically significant increase in ambulance transports following the intervention. Three studies examining ED presentations reported significantly increased ED presentations following intervention. Public educational interventions varied widely on type, duration, and content, with description of intervention development largely absent from studies, limiting the potential replication of successful interventions. Conclusions Positive intervention effects were reported in the majority of studies; however, methodological weaknesses evident in a number of studies limited the generalizability of the observed effects. Reporting of specific intervention design was suboptimal and impeded the identification of key intervention components for reducing patient delay. The parallel delivery of public and professional interventions further limited the identification of successful intervention components. A lack of studies of sound methodological quality using, at a minimum, a controlled before and after design was identified in this review, and thus studies incorporating a rigorous study design are required to strengthen the evidence for public interventions to reduce patient delay in stroke. The potential clinical benefits of public interventions are far-reaching, and the challenge remains in translating knowledge improvements and correct behavioral intentions to appropriate behavior when stroke occurs.

Abstract
Early treatment-seeking for symptoms of atrial fibrillation (AF) is critical to avert AF-related stroke and heart failure, but early treatment is hindered if symptoms are not accurately interpreted. The purpose of this research was to describe symptom representation and treatment-seeking responses prior to diagnosis of AF. For this descriptive study, 150 participants were surveyed to describe the type and temporality of symptoms, perceptions regarding the cause, seriousness, controllability of symptoms, and responses to symptoms prior to diagnosis. Participants' mean age was 66.5 years, and 51% were female. Participants perceived symptoms as having nondisease-based causes, as not very serious, and as amenable to self-management. The majority took a wait and see response with 69% waiting more than 1 week after symptom onset to seek treatment. Lack of recognition of the seriousness of symptoms of AF and delayed treatment put patients at risk of poorer outcomes.

Abstract
The purpose of this qualitative descriptive study was to explore how patients who experience acute myocardial infarction (AMI) decide to seek emergency care. Fifty patients with AMI were interviewed at two hospitals in Lebanon. The perspective of 22 witnesses of the attack was also sought about the cardiac event. The themes that transpired from the data were as follows: making sense of the symptoms, waiting to see what happens, deciding to come to the hospital, and the family influenced the decision to seek care. The witnesses of the cardiac event, mostly family members, supported the decision to seek emergency care. Deciding to seek emergency care for AMI is complex. Nurses must solicit their patients' perception of the cardiac event to provide them with tailored education and counseling about heart attack symptoms and how to respond to them in case they recur. Family members must be included in the education process.

Abstract
Introduction Delay to presentation with symptoms of acute coronary syndrome (ACS) is common meaning many fail to achieve optimal benefit from treatments. Interventions have had variable success in reducing delay. Evidence suggests inclusion of behaviour change techniques (BCTs) may improve effectiveness of interventions but this has not yet been systematically evaluated. Data from other time-critical conditions may be relevant. Methods and analysis A systematic review will be undertaken to identify which BCTs are associated with effective interventions to reduce patient delay (or prompt rapid help-seeking) among people with time-critical conditions (eg, chest pain, ACS, lumps, stroke, cancer and meningitis). A systematic search of a wide range of databases (including Cochrane Library, MEDLINE, EMBASE, CINAHL, PsycInfo) and grey literature will be undertaken to identify all relevant intervention studies (randomised controlled trials, controlled clinical trials and cohort studies). Two independent reviewers will screen abstracts to identify relevant studies, apply inclusion criteria to full papers, assess methodological quality and extract data. Primary outcome measure Change in patient decision time BCTs reported in each of the included studies will be categorised and presented according to the latest reliable taxonomy. Results of included studies will be synthesised, exploring relationships between inclusion of each BCT and effectiveness of the overall intervention. Where possible, means and SDs for differences in delay time will be calculated and combined within meta-analyses to derive a standardised mean difference and 95% CI. Analysis of (1) all time-critical and (2) ACS-only interventions will be undertaken. Ethics and dissemination No ethical issues are anticipated. Results will be submitted for publication in a relevant peer-reviewed journal.

Abstract
BACKGROUND Patients' treatment-seeking delay remains a significant barrier to timely initiation of reperfusion therapy. Measurement of treatment-seeking delay is central to the large body of research that has focused on pre-hospital delay (PHD), which is primarily patient-related. This research has aimed to quantify PHD and its effects on morbidity and mortality, identify contributing factors, and evaluate interventions to reduce such delay. A definite time of symptom onset in acute coronary syndrome (ACS) is essential for determining delay, but difficult to establish. This literature review aimed to explore the variety of operational definitions of both PHD and symptom onset in published research. METHODS AND RESULTS We reviewed the English-language literature from 1998-2013 for operational definitions of PHD and symptom onset. Of 626 papers of possible interest, 175 were deemed relevant. Ninety-seven percent reported a delay time and 84% provided an operational definition of PHD. Three definitions predominated: (a) symptom onset to decision to seek help (18%); (b) symptom onset to hospital arrival (67%), (c) total delay, incorporating two or more intervals (11%). Of those that measured delay, 8% provided a definition of which symptoms triggered the start of timing. CONCLUSION We found few and variable operational definitions of PHD, despite American College of Cardiology/American Heart Association recommendations to report specific intervals. Worryingly, definitions of symptom onset, the most elusive component of PHD to establish, are uncommon. We recommend that researchers (a) report two PHD delay intervals (onset to decision to seek care, and decision to seek care to hospital arrival), and (b) develop, validate and use a definition of symptom onset. This will increase clarity and confidence in the conclusions from, and comparisons within and between studies.

Abstract
Although coronary heart disease is the leading cause of morbidity and mortality in the Middle East (ME), not much is known about patients with ST-segment elevation myocardial infarction (STEMI) from this region. The STEMI Chain of Survival can be used to target regional improvements in patient care. We tried to adopt a modified chain of survival for STEMI to highlight the challenges and difficulties and the possible solutions to improve the STEMI care in the Middle East based on the few data available.

Abstract
BACKGROUND Research suggests that there are a number of factors which can be associated with delay in a patient seeking professional help following chest pain, including demographic and social factors. These factors may have an adverse impact on the efficacy of interventions which to date have had limited success in improving patient action times. Theory-based methods of review are becoming increasingly recognised as important additions to conventional systematic review methods. They can be useful to gain additional insights into the characteristics of effective interventions by uncovering complex underlying mechanisms. METHODS This paper describes the further analysis of research papers identified in a conventional systematic review of published evidence. The aim of this work was to investigate the theoretical frameworks underpinning studies exploring the issue of why people having a heart attack delay seeking professional medical help. The study used standard review methods to identify papers meeting the inclusion criterion, and carried out a synthesis of data relating to theoretical underpinnings. RESULTS Thirty six papers from the 53 in the original systematic review referred to a particular theoretical perspective, or contained data which related to theoretical assumptions. The most frequently mentioned theory was the self-regulatory model of illness behaviour. Papers reported the potential significance of aspects of this model including different coping mechanisms, strategies of denial and varying models of treatment seeking. Studies also drew attention to the potential role of belief systems, applied elements of attachment theory, and referred to models of maintaining integrity, ways of knowing, and the influence of gender. CONCLUSIONS The review highlights the need to examine an individual's subjective experience of and response to health threats, and confirms the gap between knowledge and changed behaviour. Interventions face key challenges if they are to influence patient perceptions regarding seriousness of symptoms; varying processes of coping; and obstacles created by patient perceptions of their role and responsibilities. A theoretical approach to review of these papers provides additional insight into the assumptions underpinning interventions, and illuminates factors which may impact on their efficacy. The method thus offers a useful supplement to conventional systematic review methods.

Abstract
BACKGROUND To study the potentially avoidable decision-making delay in acute myocardial infarction (AMI) adults male with different psychological characteristics a nationwide multicentre study was conducted in Italy by the 118 Coronary Care Units (CCUs). METHOD 929 AMI patients consecutively presented to the CCU in a conscious condition less than two hours, 2-6 hours, 6-12 hours, and more than 12 hours after symptom onset and completing the Disease Distress Questionnaire (DDQ) were enrolled in a multicentre case-control study. The DDQ collects information regarding the decision time to seek help, and includes a set of items assessing psychological factors and pain-related symptoms. The relationship between the perceived threat and the delay due to decision-making was evaluated by means of a multivariate model using LISREL 8 structural equation modelling. RESULTS The delay significantly correlated with perceived threat, which was mainly related to somatic awareness. It was only slightly related to pain and was not associated with any of the other variables. Perceived threat was also related to psychological upset, fear and health worries, the first of which was considerably influenced by emotional instability. CONCLUSION Somatic awareness is the main dimension affecting perceived threat, but subjective pain intensity affects the delay both directly and indirectly. The core of the model is the relationship between perceived threat and the delay due to decision-making. The importance of subjective pain intensity is well documented, but it is still not clear how subjective and objective pain interact.

Abstract
Calling 911 during acute coronary syndromes (ACS) decreases time to treatment and may improve prognosis. Women may have more atypical ACS symptoms compared to men, but few data are available on differences in gender and ACS symptoms in calling 911. In this study, patient interviews and structured chart reviews were conducted to determine gender differences in calling 911. Calls to 911 were assessed by self-report and validated by medical chart review. Of the 476 patients studied, 292 (61%) were diagnosed with unstable angina and 184 (39%) with myocardial infarctions (MIs). Overall, only 23% of patients called 911. Similar percentages of women and men with unstable angina called 911 (15% and 13%, respectively, p = 0.59). In contrast, women with MIs were significantly more likely to call 911 than men (57% vs 28%, p <0.001). After adjustment for sociodemographic factors, health insurance status, history of MI, the left ventricular ejection fraction, Global Registry of Acute Coronary Events (GRACE) score, and ACS symptoms, women were 1.79 times more likely to call 911 during an MI than men (prevalence ratio 1.79, 95% confidence interval 1.22 to 2.64, p <0.01). In conclusion, the findings of the present study suggest that initiatives to increase calls to 911 are needed for women and men.

Abstract
BACKGROUND The role of troponin quantification in evaluation of patients with suspected acute coronary syndrome is established, but with cost implications. Emerging high-sensitivity troponin and novel multi-marker assays herald further resource implications. AIMS The objective of this study was to quantify recent trends in troponin usage and costs in a cross-section of hospitals. METHODS A cross-sectional survey seeking data on troponin usage and costs from six tertiary referral, public access teaching hospitals for consecutive years between 2003 and 2009 was carried out. RESULTS A median annual increase in the volume of troponin assays requested was identified in all six hospitals, with an average median annual increase of 6.9 % across hospitals (interquartile range 3.4, 10.1 %). This annual increase was not accompanied by a corresponding increase in volume of patients presenting to the Emergency Department (ED) with chest pain. The majority (44-67 %) of troponin requests originated in the ED of hospitals. The median annual spend on troponins per hospital was <euro>115,612 (interquartile range <euro>80,452, <euro>140,918). An analysis of results of assays performed in one centre found that the majority (91 %) of troponin assays performed were in the normal range. CONCLUSIONS An annual increase in troponin requests without a corresponding increase in patient activity raises the possibility of increasingly indiscriminate troponin testing. The cumulative direct and indirect costs of inappropriate testing are significant. Corrective strategies are necessary to improve patient selection and testing protocols, particularly in the advent of the high-sensitivity troponin assays and novel multi-marker strategies.

[PMID: 22633702 DOI: 10.1016/j.ajem.2012.03.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2011] [Revised: 03/03/2012] [Accepted: 03/03/2012] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVES Symptoms are compared among patients with coronary artery disease (CAD) admitted to the emergency department with or without acute coronary syndrome (ACS). Sex and age are also assessed. METHODS A secondary analysis from the PROMOTION (Patient Response tO Myocardial Infarction fOllowing a Teaching Intervention Offered by Nurses) trial, an multicenter randomized controlled trial, was conducted. RESULTS Of 3522 patients with CAD, at 2 years, 565 (16%) presented to the emergency department, 234 (41%) with non-ACS and 331 (59%) with ACS. Shortness of breath (33% vs 25%, P = .028) or dizziness (11% vs 3%, P = .001) were more common in non-ACS. Chest pain (65% vs 77%, P = .002) or arm pain (9% vs 21%, P = .001) were more common in ACS. In men without ACS, dizziness was more common (11% vs 2%; P = .001). Men with ACS were more likely to have chest pain (78% vs 64%; P = .003); both men and women with ACS more often had arm pain (men, 19% vs 10% [P = .019]; women, 26% vs 13% [P = .023]). In multivariate analysis, patients with shortness of breath (odds ratio [OR], 0.617 [confidence interval [CI], 0.410-0.929]; P = .021) or dizziness (OR, .0311 [CI, 0.136-0.708]; P = .005) were more likely to have non-ACS. Patients with prior percutaneous coronary intervention (OR, 1.592 [CI, 1.087-2.332]; P = .017), chest pain (OR, 1.579 [CI, 1.051-2.375]; P = .028), or arm pain (OR, 1.751 [CI, 1.013-3.025]; P <.042) were more likely to have ACS. CONCLUSIONS In patients with CAD, shortness of breath and dizziness are more common in non-ACS, whereas prior percutaneous coronary intervention and chest or arm pain are important factors to include during ACS triage.

Abstract
BACKGROUND Patient delay in seeking treatment for acute coronary syndrome symptoms remains a problem. Thus, it is vital to test interventions to improve this behavior, but at the same time it is essential that interventions not increase anxiety. PURPOSE To determine the impact on anxiety and perceived control of an individual face-to-face education and counseling intervention designed to decrease patient delay in seeking treatment for acute coronary syndrome symptoms. METHODS This was a multicenter randomized controlled trial of the intervention in which anxiety data were collected at baseline, 3-months and 12-months. A total of 3522 patients with confirmed coronary artery disease were enrolled; data from 2597 patients with anxiety data at all time points are included. The intervention was a 45 min education and counseling session, in which the social, cognitive and emotional responses to acute coronary syndrome symptoms were discussed as were barriers to early treatment seeking. Repeated measures analysis of covariance was used to compare anxiety and perceived control levels across time between the groups controlling for age, gender, ethnicity, education level, and comorbidities. RESULTS There were significant differences in anxiety by group (p = 0.03). Anxiety level was stable in patients in the control group, but decreased across time in the intervention group. Perceived control increased across time in the intervention group and remained unchanged in the control group (p = 0.01). CONCLUSION Interventions in which cardiac patients directly confront the possibility of an acute cardiac event do not cause anxiety if they provide patients with appropriate strategies for managing symptoms.

Abstract
BACKGROUND Patient delay in recognizing and responding to potential acute myocardial infarction (AMI) symptoms is an international issue. Cardiac rehabilitation provides an ideal opportunity to deliver an intervention. AIMS This study examines an individual educational intervention on knowledge of heart attack warning signs and specific chest pain action plans for people with coronary heart disease. METHODS Cardiac rehabilitation participants at five hospitals were assessed at program entry and tailored education was provided using the Heart Foundation of Australia's Heart Attack Warning Signs campaign educational tool. Participants (n=137) were reassessed at program conclusion (six to eight weeks). RESULTS Study participants had a mean age of 64.48 years (SD 12.22), were predominantly male (78%) and most commonly presented with a current referral diagnosis of a percutaneous coronary intervention (PCI) (80%) and/or AMI (60%). There were statistically significant improvements in the reporting of 11 of the 14 warning signs of heart attack, with patients reporting 2.56 more warning signs on average at outcome (p<.0001). Patients reported more heart attack warning signs if they had completed high school education (β=1.14) or had better knowledge before the intervention (β=.57). There were statistically significant improvements in reporting of all appropriate actions in response to potential AMI symptoms, with patients reporting an average of 1.3 more actions at outcome (p<.001), with no change in the median time they would tolerate symptoms (p=.16). CONCLUSIONS A brief education session using a single standardised tool and adapted to a patient assessment is effective in improving knowledge of potential AMI symptoms and appropriate responses in cardiac rehabilitation up to two months following.

Abstract
AIMS To investigate the relationship between anxiety, perceived control and rate of in-hospital complications after acute coronary syndrome. BACKGROUND Anxiety may be associated with higher risk of complications following acute myocardial infarction; perceived control may moderate this relationship. DESIGN Prospective observational study. METHODS Patients enrolled in a trial investigating delay in seeking treatment for acute coronary syndrome had anxiety measured at enrolment and 3 months using the Brief Symptom Inventory anxiety subscale. The acute coronary syndrome hospital presentations investigated occurred between 2001-2006. Patients with anxiety scores greater than the population norm at both time points were categorized as persistently anxious. Perceived control was measured at enrolment using the control attitudes scale-revised. Data were collected from the medical record on in-hospital complications in patients presenting with acute coronary syndrome within 2 years of enrolment. Chi-square and t-tests were used for univariate analyses and multiple logistic regression to identify independent predictors of complications. RESULTS Patients (n = 171) were 64% men with mean age 69 years. Ischaemic or arrhythmic complications occurred in 26 patients (15%) with no difference in complication rates between those persistently anxious and others. Important univariate predictors of in-hospital complications were lower perceived control, diagnosis of acute myocardial infarction, heart failure and higher pulse rate on admission. Low perceived control and diagnosis of acute myocardial infarction were independent predictors of in-hospital complications in the multiple logistic regression. CONCLUSION Perceived control, but not persistent anxiety, prior to acute coronary syndrome was an important predictor of in-hospital complications after acute coronary syndrome. Interventions to increase cardiac patients' perceived control of their cardiac illness may reduce in-hospital complications after acute coronary syndrome.

Women's Experiences and Behaviour at Onset of Symptoms of ST Segment Elevation Acute Myocardial Infarction. Eur J Cardiovasc Nurs 2011; 10:241-7. [DOI: 10.1016/j.ejcnurse.2010.10.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2010] [Revised: 10/07/2010] [Accepted: 10/08/2010] [Indexed: 11/20/2022]
Abstract
Background: Minimizing time from onset of symptoms to treatment (treatment delay) is crucial for patients with ST segment elevation acute myocardial infarction (STEMI), and one of the great challenges is to reduce the delay relating to the prehospital behaviour of the patient (patient delay). Studies indicate that women delay longer than men and insights into this area could lead to improved health education programmes aimed at reducing patient delay in women with STEMI. Method: Open interviews with 14 women with STEMI were held during their hospital stay from June to September 2009. The interviews were aimed at exploring determinants of treatment delay, and were carried out and analysed within a phenomenological framework. Findings: Three themes emerged important for the delay in seeking medical assistance: (1) Knowledge and ideas of AMI symptoms and risks. (2) Ambivalence whether to call for medical assistance or to cope with the situation. (3) Actions and strategies taken after onset of symptoms. Conclusions: Three factors determined whether women showed appropriate behaviour for reduced patient delay after onset of symptoms: (1) identifying the symptoms as being of cardiac origin, (2) having a prepared action plan in case of an emergency situation, and (3) living with someone or contacting other persons.

Abstract
BACKGROUND Increased delay to hospital presentation with acute coronary syndrome (ACS) is associated with poor outcomes. While demographic factors associated with this delay have been well described, scarce data are available on the role of modifiable factors, such as psychosocial disorders, on pre-hospital delay. Patients with symptoms of post-traumatic stress disorder (PTSD) often avoid stressful situations and may delay presenting for care when they experience cardiac symptoms. It is unknown, however, whether PTSD symptoms negatively impact the time to presentation during an ACS. METHODS We assessed the relationship between PTSD symptoms and pre-hospital delay in 241 adults with an ACS in the ongoing Prescription Use, Lifestyle, Stress Evaluation (PULSE) study. RESULTS Overall, 66% of patients were male; 40% were Hispanic or Latino. The mean age was 61.9±11.6 years old. PTSD symptoms were present in 17.8% of patients. Pre-hospital delay was longer for patients with PTSD symptoms compared to those without [geometric mean: 25.8 hours (95% CI 13.8-44.8) vs. 10.7 hours (95% CI 8.3-13.8)]; P = 0.005. After multivariable adjustment for age, sex, ethnicity, depression, left ventricular ejection fraction and history of myocardial infarction, the mean pre-hospital delay was 173% (95% CI: 36%-450%) longer for patients with versus without PTSD symptoms. CONCLUSION Among patients presenting with an ACS, PTSD symptoms were independently associated with longer pre-hospital delays. Future studies of pre-hospital delay should examine the mechanisms underlying this association.

Abstract
OBJECTIVE Prolonged prehospital delay in persons experiencing acute coronary syndrome (ACS) remains a problem. Understanding which patients respond best to particular interventions designed to decrease delay time would provide mechanistic insights into the process by which interventions work. METHODS In the PROMOTION trial, 3522 at-risk patients were enrolled from 5 sites in the United States (56.4%), Australia and New Zealand; 490 (N=272 intervention, N=218 control) had an acute event within 2 years. Focusing on these 490, we (1) identified predictors of a rapid response to symptoms, (2) identified intervention group subjects with a change in these predictors over 3 months of follow-up, and (3) compared intervention group participants with and without the favorable response pattern. Hypothesized predictors of rapid response were increased perceived control and decreased anxiety. Knowledge, attitudes, and beliefs were hypothesized to differ between responders and non-responders. RESULTS Contrary to hypothesis, responders had low anxiety and low perceived control. Only 73 (26.8%) subjects showed this pattern 3 months following the intervention. No differences in ACS knowledge, attitudes, or beliefs were found. CONCLUSION The results of this study challenge existing beliefs. PRACTICE IMPLICATIONS New intervention approaches that focus on a realistic decrease in anxiety and perceived control are needed.

Abstract
OBJECTIVE To examine the association of symptoms of persistent anxiety with the development of acute cardiac events in patients with coronary heart disease (CHD) followed for 2 years. The prevalence of symptoms of anxiety is high in patients with CHD, but their effect on cardiac events and mortality has not been well characterized. METHODS Of 3522 patients with confirmed CHD enrolled, data on symptoms of anxiety were available at two time points in 3048 patients who were then followed up for detection of the composite end point of hospitalization for myocardial infarction, unstable or stable angina, other cardiac causes, or all-cause mortality. A composite anxiety symptoms score composed of baseline and 3-month anxiety data, in which the continuous-level scores were used, was tested using Cox proportional hazards regression model. Groups (persistent anxiety [anxiety at both time points] versus nonanxious [no anxiety at either time point] versus not persistently anxious [anxiety only at one time point]) were also compared. RESULTS Symptoms of persistent anxiety, whether considered as a continuous- or categorical-level variable, were associated with shorter time to event. Persistent anxiety remained as an independent predictor of the end point after controlling for multiple variables (persistent anxiety as a summary score [hazard ratio = 1.27, 95% confidence interval = 1.067-1.514] and persistent anxiety as a categorical variable [hazard ratio = 1.52, 95% confidence interval = 1.149-2.015]). CONCLUSIONS By measuring anxiety symptoms at more than one time point and controlling for relevant sociodemographic, comorbidity, risk factor, and psychological covariates, we illustrate that symptoms of persistent anxiety are a strong, independent predictor of cardiac event-free survival.

Abstract
BACKGROUND Coronary artery disease is the most common cause of death in the Western world, and being married decreases the risk of death from cardiovascular causes. We aimed to determine whether marital status was a predictor of the duration of chest pain endured by patients with acute myocardial infarction before they sought care and whether the patient's sex modified the effect. METHODS We conducted a retrospective, population-based cohort analysis of patients with acute myocardial infarction admitted to 96 acute care hospitals in Ontario, Canada, from April 2004 to March 2005. We excluded patients who did not experience chest pain. Using multivariable regression analyses, we assessed marital status in relation to delayed presentation to hospital (more than six hours from onset of pain), both overall and stratified by sex. In patients who reported the exact duration of chest pain, we assessed the effect of marital status on the delay in seeking care. RESULTS Among 4403 eligible patients with acute myocardial infarction, the mean age was 67.3 (standard deviation 13.6) years, and 1486 (33.7%) were women. Almost half (2037 or 46.3%) presented to a hospital within two hours, and 3240 (73.6%) presented within six hours. Overall, 75.3% (2317/3079) of married patients, 67.9% (188/277) of single patients, 68.5% (189/276) of divorced patients and 70.8% (546/771) of widowed patients presented within six hours of the onset of chest pain. Being married was associated with lower odds of delayed presentation (odds ratio [OR] 0.46, 95% confidence interval [CI] 0.30-0.71, p < 0.001) relative to being single. Among men, the OR was 0.35 (95% CI 0.21-0.59, p < 0.001), whereas among women the effect of marital status was not significant (OR 1.36, 95% CI 0.49-3.73, p = 0.55). INTERPRETATION Among men experiencing acute myocardial infarction with chest pain, being married was associated with significantly earlier presentation for care, a benefit that was not observed for married women. Earlier presentation for medical care appears to be one reason for the observed lower risk of cardiovascular death among married men, relative to their single counterparts.

Abstract
BACKGROUND Activation of emergency medical services (EMS) is critical for the early triage and treatment of patients experiencing ST-segment-elevation myocardial infarction, yet data regarding EMS use and its association with subsequent clinical care are limited. METHODS AND RESULTS We performed an observational analysis of 37 634 ST-segment-elevation myocardial infarction patients treated at 372 US hospitals participating in the National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With the Guidelines between January 2007 and September 2009, and examined independent patient factors associated with EMS transportation versus patient self-transportation. We found that EMS transport was used in only 60% of ST-segment-elevation myocardial infarction patients. Older patients, those living farther from the hospital, and those with hemodynamic compromise were more likely to use EMS transport. In contrast, race, income, and education level did not appear to be associated with the mode of transport. Compared with self-transported patients, EMS-transported patients had significantly shorter delays in both symptom-onset-to-arrival time (median, 89 versus 120 minutes; P<0.0001) and door-to-reperfusion time (median door-to-balloon time, 63 versus 76 minutes; P<0.0001; median door-to-needle time, 23 versus 29 minutes; P<0.0001). CONCLUSIONS Emergency medical services transportation to the hospital is underused among contemporary ST-segment-elevation myocardial infarction patients. Nevertheless, use of EMS transportation is associated with substantial reductions in ischemic time and treatment delays. Community education efforts are needed to improve the use of emergency transport as part of system-wide strategies to improve ST-segment-elevation myocardial infarction reperfusion care.

Abstract
OBJECTIVE : Recognizing reasons for prehospital delay after symptoms of acute coronary syndrome (ACS) is established in developed countries yet evidence from Latin America is limited. We aimed to assess ACS symptom recognition, health care-seeking behavior, and confidence in local health care facilities to take care of ACS by gender in a sample of Peruvians. METHODS : A community-based interview survey in a peri-urban area in Lima, Peru. The 24-item study instrument included vignettes and questions assessing identification of urgent and emergent ACS symptoms, anticipated help-seeking behaviors, and confidence in local health care facilities. RESULTS : In the study population (90 people; 45.6% men; mean age, 43.5 years), women were 4 times less likely to correctly attribute symptoms of chest pain to the heart (OR = 0.23; 95% CI: 0.063-0.87; P = 0.03). Women were much more likely to respond that a man would "Seek help" (OR = 4.54; 95% CI: 1.21-16.90; P = 0.024) and that "Yes," a woman would be less likely to seek help for chest pain symptoms (OR = 3.26; 95% CI: 1.13-9.41 P = 0.029) after adjusting for age, education level, age at migration, and history of chest pain. Women were less likely than men to think that their local Health Care Post would help them if they had a heart attack (2.1% vs. 14.6%; P = 0.04), and only 18.7% of women believed that their local emergency room would help them. CONCLUSIONS : Our findings suggest women are less likely to seek help for chest pain and women and men in a peri-urban area in Peru are not confident in their local health care facility to treat urgent or emergent ACS symptoms.

Abstract
Background Early hospital arrival and rapid intervention for acute myocardial infarction is essential for a successful outcome. Several studies have been unable to identify explanatory factors that slowed decision time. The present study examines whether personality, psychosocial factors, and coping strategies might explain differences in time delay from onset of symptoms of acute myocardial infarction to arrival at a hospital emergency room. Methods Questionnaires on coping strategies, personality dimensions, and depression were completed by 323 patients ages 26 to 70 who had suffered an acute myocardial infarction. Tests measuring stress adaptation were completed by 180 of them. The patients were then categorised into three groups, based on time from onset of symptoms until arrival at hospital, and compared using logistic regression analysis and general linear models. Results No correlation could be established between personality factors (i.e., extraversion, neuroticism, openness, agreeableness, conscientiousness) or depressive symptoms and time between onset of symptoms and arrival at hospital. Nor was there any significant relationship between self-reported patient coping strategies and time delay. Conclusions We found no significant relationship between personality factors, coping strategies, or depression and time delays in seeking hospital after an acute myocardial infraction.

Abstract
Health education aims at the acquisition of skills and attitudes to modify behaviour that influences health, leads to a modification of risk factors and ultimately to a decrease in disability and case fatality from stroke. Health education is an underdeveloped but important aspect of stroke care. Health education could promote compliance and healthy behaviour, improve patients' understanding of their health status and treatment options and facilitate communication. We reviewed the effect of health education in stroke and transient ischaemic attack patients, aiming at feasibility, effectiveness at the level of knowledge, attitude and skills, health behaviour changes and stroke outcome. We also describe the current status of health education for patients with recent coronary artery disease and public health education in stroke. Basic knowledge of stroke and transient ischaemic attack patients of their disease and associated risk factors is not sufficient. This is also observed in patients with coronary artery disease and in the general population. A beneficial effect of health education in stroke and transient ischaemic attack patients on health behaviour, risk reduction or stroke outcome has not been proven. Trials in patients with coronary artery disease, however, have shown that health education could result in a change of lifestyle. No specific method is superior, although the individualised, repetitive and active methods appear more successful. More intervention studies of health education in stroke and transient ischaemic attack patients are needed. Future trials should be large, have a long follow-up, should use an intensive and repetitive approach and involve patients' relatives to induce and maintain a healthy lifestyle.

Abstract
OBJECTIVES To report time from the onset of symptoms to hospital presentation in Australian and New Zealand patients with subsequently confirmed acute coronary syndrome, and to identify factors associated with prehospital delay time in these patients. METHODS Patients with coronary artery disease enrolled in a randomized clinical trial testing an intervention to reduce delay in responding to acute coronary syndrome symptoms had been followed for 24 months. In cases of admission to the ED for possible acute coronary syndrome, medical records were reviewed to determine the diagnosis, prehospital delay time, mode of transport to the hospital and aspirin use before admission. Clinical and demographic data were taken from the trial database. RESULTS Patients (n= 140) had an average (SD) age of 67.3 (11.5) years; 36% were female. Two-thirds of patients went to hospital by ambulance and 89.3% had a final diagnosis of unstable angina. The median time from onset of symptoms to arrival at the ED was 2 h and 25 min (interquartile range 1:25-4:59); 12.1% arrived ≤ 1 h and 66% within 4 h. Multiple linear regression analysis showed that use of ambulance (Beta = 0.247, P= 0.012) and younger age (Beta = 0.198, P= 0.043) were independent predictors of shorter delay times. CONCLUSION The time from the onset of symptoms to hospital presentation was too long for maximal benefit from treatment in most patients. Further efforts are needed to reduce treatment-seeking delay in response to symptoms of acute coronary syndrome.

Abstract
BACKGROUND The prompt administration of coronary reperfusion therapy for patients with an evolving acute myocardial infarction (AMI) is crucial in reducing mortality and the risk of serious clinical complications in these patients. However, long-term trends in extent of prehospital delay and factors affecting patient's care-seeking behavior remain relatively unexplored, especially in men and women of different ages. The objectives of this study were to examine the overall magnitude and 20-year trends (1986 to 2005) in duration of prehospital delay in middle-aged and elderly men and women hospitalized with AMI. METHODS AND RESULTS The study sample consisted of 5967 residents of the Worcester, Mass, metropolitan area hospitalized at all greater Worcester medical centers for AMI between 1986 and 2005 who had information available about duration of prehospital delay. Compared with men <65 years, patients in other age-sex strata exhibited longer prehospital delays over the 20-year period under study. The multivariable-adjusted medians of prehospital delay were 1.96, 2.07, and 2.57 hours for men <65 years, men 65 to 74 years, and men ≥75 years and 2.08, 2.33, and 2.27 hours for women <65 years, women 65 to 74 years, and women ≥75 years, respectively. These age and sex differences have narrowed over time, which has been largely explained by changes in patient's comorbidity profile and AMI-associated characteristics. CONCLUSIONS Our results suggest that duration of prehospital delay in persons with symptoms of AMI has remained essentially unchanged during the 20-year period under study and elderly individuals are more likely to delay seeking timely medical care than younger persons.

Abstract
Background The two major complications of atherosclerosis are acute myocardial infarction (AMI) and acute ischemic stroke. Both are life-threatening conditions characterised by the abrupt cessation of blood flow to respective organs, resulting in an infarction. Depending on the extent of the infarction, loss of organ function varies considerably. In both conditions, it is possible to limit the extent of infarction with early intervention. In both conditions, minutes count. This article aims to describe differences and similarities with regard to the way patients, bystanders and health care providers act in the acute phase of the two diseases with the emphasis on the pre-hospital phase. Method A literature search was performed on the PubMed, Embase (Ovid SP) and Cochrane Library databases. Results In both conditions, symptoms vary considerably. Patients appear to suspect AMI more frequently than stroke and, in the former, there is a gender gap (men suspect AMI more frequently than women). With regard to detection of AMI and stroke at dispatch centre and in Emergency Medical Service (EMS) there is room for improvement in both conditions. The use of EMS appears to be higher in stroke but the overall delay to hospital admission is shorter in AMI. In both conditions, the fast track concept has been shown to influence the delay to treatment considerably. In terms of diagnostic evaluation by the EMS, more supported instruments are available in AMI than in stroke. Knowledge of the importance of early treatment has been reported to influence delays in both AMI and stroke. Conclusion Both in AMI and stroke minutes count and therefore the fast track concept has been introduced. Time to treatment still appears to be longer in stroke than in AMI. In the future improvement in the early detection as well as further shortening to start of treatment will be in focus in both conditions. A collaboration between cardiologists and neurologists and also between pre-hospital and in-hospital care might be fruitful.

Abstract
CONTEXT Little is known about how health insurance status affects decisions to seek care during emergency medical conditions such as acute myocardial infarction (AMI). OBJECTIVE To examine the association between lack of health insurance and financial concerns about accessing care among those with health insurance, and the time from symptom onset to hospital presentation (prehospital delays) during AMI. DESIGN, SETTING, AND PATIENTS Multicenter, prospective study using a registry of 3721 AMI patients enrolled between April 11, 2005, and December 31, 2008, at 24 US hospitals. Health insurance status was categorized as insured without financial concerns, insured but have financial concerns about accessing care, and uninsured. Insurance information was determined from medical records while financial concerns among those with health insurance were determined from structured interviews. MAIN OUTCOME MEASURE Prehospital delay times (< or = 2 hours, > 2-6 hours, or > 6 hours), adjusted for demographic, clinical, and social and psychological factors using hierarchical ordinal regression models. RESULTS Of 3721 patients, 2294 were insured without financial concerns (61.7%), 689 were insured but had financial concerns about accessing care (18.5%), and 738 were uninsured (19.8%). Uninsured and insured patients with financial concerns were more likely to delay seeking care during AMI and had prehospital delays of greater than 6 hours among 48.6% of uninsured patients and 44.6% of insured patients with financial concerns compared with only 39.3% of insured patients without financial concerns. Prehospital delays of less than 2 hours during AMI occurred among 36.6% of those insured without financial concerns compared with 33.5% of insured patients with financial concerns and 27.5% of uninsured patients (P < .001). After adjusting for potential confounders, prehospital delays were associated with insured patients with financial concerns (adjusted odds ratio, 1.21 [95% confidence interval, 1.05-1.41]; P = .01) and with uninsured patients (adjusted odds ratio, 1.38 [95% confidence interval, 1.17-1.63]; P < .001). CONCLUSION Lack of health insurance and financial concerns about accessing care among those with health insurance were each associated with delays in seeking emergency care for AMI.

Abstract
BACKGROUND The timely and accurate identification of symptoms of acute coronary syndrome (ACS) is a challenge for patients and clinicians. It is unknown whether response times and clinical outcomes differ with specific symptoms. We sought to identify which ACS symptoms are related-symptom clusters-and to determine if sample characteristics, response times, and outcomes differ among symptom cluster groups. METHODS In a multisite randomized clinical trial, 3522 patients with known cardiovascular disease were followed up for 2 years. During follow-up, 331 (11%) had a confirmed ACS event. In this group, 8 presenting symptoms were analyzed using cluster analysis. Differences in symptom cluster group characteristics, delay times, and outcomes were examined. RESULTS The sample was predominantly male (67%), older (mean 67.8, S.D. 11.6 years), and white (90%). Four symptom clusters were identified: Classic ACS characterized by chest pain; Pain Symptoms (neck, throat, jaw, back, shoulder, arm pain); Stress Symptoms (shortness of breath, sweating, nausea, indigestion, dread, anxiety); and Diffuse Symptoms, with a low frequency of most symptoms. Those in the Diffuse Symptoms cluster tended to be older (P = .08) and the Pain Symptoms group was most likely to have a history of angina (P = .01). After adjusting for differences, the Diffuse Symptoms cluster demonstrated higher mortality at 2 years (17%) than the other 3 clusters (2%-5%, P < .001), although prehospital delay time did not differ significantly. CONCLUSION Most ACS symptoms occur in groups or clusters. Uncharacteristic symptom patterns may delay diagnosis and treatment by clinicians even when patients seek care rapidly. Knowledge of common symptom patterns may facilitate rapid identification of ACS.

Abstract
BACKGROUND Coronary heart disease is the leading cause of morbidity and mortality in American men and women. Although there have been dramatic changes in the management of patients hospitalized with acute myocardial infarction (AMI) over the past several decades, a considerable proportion of patients with AMI continue to delay seeking medical care in a timely manner. This review provides an overview of the published literature that has examined age and sex differences in extent of prehospital delay in patients hospitalized with AMI. METHODS AND RESULTS A systematic review of the literature from 1960 to 2008, including publications that provided data on duration of prehospital delay in patients hospitalized with AMI, was conducted. A total of 44 articles (42 studies) were included in the present analysis. The majority of studies showed that in patients hospitalized with AMI, women and older persons were more likely to arrive at the hospital later than men and younger persons. Several factors associated with duration of prehospital delay, including sociodemographic, medical history, clinical, and contextual characteristics differed according to sex. CONCLUSIONS The elderly and women were more likely to exhibit longer delays in seeking medical care after the development of symptoms suggestive of AMI compared with other groups. Further research is needed to more fully understand the reasons for delay in these vulnerable groups.

Abstract
BACKGROUND Coronary heart disease (CHD) and acute coronary syndrome (ACS) remain significant public health problems. The effect of ACS on mortality and morbidity is largely dependent on the time from symptom onset to the time of reperfusion, but patient delay in presenting for treatment is the main reason timely reperfusion is not received. OBJECTIVES We tested the effect of an education and counseling intervention on knowledge, attitudes and beliefs about ACS symptoms and the appropriate response to symptoms, and identified patient characteristics associated with changes in knowledge, attitudes and beliefs over time. METHODS We conducted a two-group randomized controlled trial in 3522 people with CHD. The intervention group received a 40 min, one-on-one education and counseling session. The control group received usual care. Knowledge, attitudes and beliefs were measured at baseline, 3 and 12 months using the ACS Response Index and analyzed with repeated measures analysis of variance. RESULTS Knowledge, attitudes and beliefs scores increased significantly from baseline in the intervention group compared to the control group at 3 months, and these differences were sustained at 12 months (p=.0005 for all). Higher perceived control over cardiac illness was associated with more positive attitudes (p<.0005) and higher state anxiety was associated with lower levels of knowledge (p<.05), attitudes (p<.05) and beliefs (p<.0005). CONCLUSION A relatively short education and counseling intervention increased knowledge, attitudes and beliefs about ACS and response to ACS symptoms in individuals with CHD. Higher perceived control over cardiac illness was associated with more positive attitudes and higher state anxiety was associated with lower levels of knowledge, attitudes and beliefs about responding to the health threat of possible ACS.
