- Aim: In ST-elevation myocardial infarction, time to reperfusion is crucial for the prognosis. Symptom presentation in myocardial infarction influences pre-hospital delay times but studies about differences in symptoms between patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction are sparse and inconclusive. The aim was to compare symptoms, first medical contact and pre-hospital delay times in patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction.Methods and results: This multicentre, observational study included 694 myocardial infarction patients from five hospitals. The patients filled in a questionnaire about their pre-hospital experiences within 24 h of hospital admittance. Chest pain was the most common symptom in ST-elevation myocardial infarction and non-ST-elevation myocardial infarction (88.7 vs 87.0%, p=0.56). Patients with cold sweat (odds ratio 3.61, 95% confidence interval 2.29–5.70), jaw pain (odds ratio 2.41, 95% confidence interval 1.04–5.58), and nausea (odds ratio 1.70, 95% confidence interval 1.01–2.87) were more likely to present with ST-elevation myocardial infarction, whereas the opposite was true for symptoms that come and go (odds ratio 0.58, 95% confidence interval 0.38-0.90) or anxiety (odds ratio 0.52, 95% confidence interval 0.29–0.92). Use of emergency medical services was higher among patients admitted with ST-elevation myocardial infarction. The pre-hospital delay time from symptom onset to first medical contact was significantly longer in non-ST-elevation myocardial infarction (2:05 h vs 1:10 h, p=0.001).Conclusion: Patients with ST-elevation myocardial infarction differed from those with non-ST-elevation myocardial infarction regarding symptom presentation, ambulance utilisation and pre-hospital delay times. This knowledge is important to be aware of for all healthcare personnel and the general public especially in order to recognise symptoms suggestive of ST-elevation myocardial infarction and when to decide if there is a need for an ambulance.

- Background: Geographical variations in cardiovascular mortality have been reported in Sweden as well as in other countries. Little attention has been given to possible variations in symptoms, actions and pre-hospital delay times in ST-elevation myocardial infarction (STEMI) patients, as a reason for this diversity. We aimed to study whether STEMI patients from the northern and southern parts of Sweden differ in symptoms and actions that may affect the pre-hospital delay times.Methods: SymTime was a multicentre cross-sectional survey study where STEMI patients admitted to the coronary care unit completed a validated questionnaire within 24 hours after admission. In total, 531 patients were included, 357 in the southern and 174 in the northern part of Sweden.Results: There were no significant differences in age. However, patients in the north had more often hypertension (52 vs 42%, p=0.02) or other concomitant comorbidities (24 vs 14%, p=0.01). Patients in the south experienced more anxiety (14 vs. 7%, p=0.01) and fear (23 vs. 14%, p=0.02) and more often contacted the emergency medical services (EMS) as first medical contact (FMC) (54 vs 44%, p=0.05). There were no differences in other main or associated symptoms or in pre-hospital delay times. Conclusions: Patients with STEMI in the southern vs. the northern part of Sweden had more anxiety and fear, despite that they were less often alone at onset of symptoms. There were no differences in pre-hospital delay times. Although patients from the southern region contacted EMS as their FMC more frequently, it is still worrying that too few patients utilize the EMS.

- BACKGROUND: Symptom presentation has been sparsely studied from a gender perspective restricting the inclusion to ST elevation myocardial infarction (STEMI) patients. Correct symptom recognition is vital in order to promptly seek care in STEMI where fast reperfusion therapy is of utmost importance. Female gender has been found associated with atypical presentation in studies on mixed MI populations but it is unclear whether this is valid also in STEMI.OBJECTIVES: We assessed whether there are gender differences in symptoms and interpretation of these in STEMI, and if this is attributable to sociodemographic and clinical factors.METHODS: SymTime was a multicenter observational study including a validated questionnaire and data from medical records. Eligible STEMI patients (n = 532) were enrolled within 24 h after admittance at five Swedish hospitals.RESULTS: Women were older, more often single and had lower educational level. Chest pain was less prevalent in women (74 vs 93%, p < 0.001), whereas shoulder (33 vs 15%, p < 0.001), throat/neck (34 vs 18%, p < 0.001), back pain (29 versus 12%, p < 0.001) and nausea (49 vs 29%, p < 0.001) were more prevalent. Women less often interpreted their symptoms as of cardiac origin (60 vs 69%, p = 0.04). Female gender was the strongest independent predictor of non-chest pain presentation, odds ratio 5.29, 95% confidence interval 2.85-9.80.CONCLUSIONS: A striking gender difference in STEMI symptoms was found. As women significantly misinterpreted their symptoms more often, it is vital when informing about MI to the society or to high risk individuals, to highlight also other symptoms than just chest pain.

- OBJECTIVES: Compare gender disparities in ST-elevation myocardial infarction (STEMI) regarding first medical contact (FMC) and prehospital delay times and explore factors associated with prehospital delay in men and women separately.DESIGN: Cross-sectional study based on medical records and a validated questionnaire. Eligible patients were enrolled within 24 hours after admittance to hospital.SETTING: Patients were included from November 2012 to January 2014 from five Swedish hospitals with catheterisation facilities 24/7.PARTICIPANTS: 340 men and 109 women aged between 31 and 95 years completed the survey.MAIN OUTCOME MEASURES: FMC were divided into five possible contacts: primary healthcare centre by phone or directly, national advisory nurse by phone, emergency medical services (EMS) and emergency room directly. Two parts of prehospital delay times were studied: time from symptom onset to FMC and time from symptom onset to diagnostic ECG.RESULTS: Women more often called an advisory nurse as FMC (28% vs 18%, p=0.02). They had a longer delay until FMC, 90 (IQR 39-221) vs 66 (28-161) min, p=0.04 and until ECG, 146 (68-316) vs 103 (61-221) min, p=0.03. Men went to hospital because of believing they were stricken by an MI to a higher extent than women did (25% vs 15%, p=0.04) and were more often recommended to call EMS by bystanders (38% vs 22%, p<0.01). Hesitating about going to hospital and experiencing pain in the stomach/back/shoulders were factors associated with longer delays in women. Believing the symptoms would disappear or interpreting them as nothing serious were corresponding factors in men. In both genders bystanders acting by contacting EMS explained shorter prehospital delays.CONCLUSIONS: In STEMI, women differed from men in FMC and they had longer delays. This was partly due to atypical symptoms and a longer decision time. Bystanders acted more promptly when men than when women fell ill. Public knowledge of MI symptoms, and how to act properly, still seems insufficient.

- OBJECTIVE: It is unknown into what extent patients with ST-elevation myocardial infarction (STEMI) utilise a joint service number (Swedish Healthcare Direct, SHD) as first medical contact (FMC) instead of Emergency Medical Services (EMS) and how this impact time to diagnosis. We aimed to (1) describe patients' FMC; (2) find explanatory factors influencing their FMC (ie, EMS and SHD) and (3) explore the time interval from symptom onset to diagnosis.SETTING: Multicentred study, Sweden.METHODS: Cross-sectional, enrolling patients with consecutive STEMI admitted within 24 h from admission.RESULTS: We included 109 women and 336 men (mean age 66±11 years). Although 83% arrived by ambulance to the hospital, just half of the patients (51%) called EMS as their FMC. Other utilised SHD (21%), contacted their primary healthcare centre (14%), or went directly to the emergency room (14%). Reasons for not contacting EMS were predominantly; (1) my transport mode was faster (40%), (2) did not consider myself sick enough (30%), and (3) it was easier to be driven or taking a taxi (25%). Predictors associated with contacting SHD as FMC were female gender (OR 1.92), higher education (OR 2.40), history of diabetes (OR 2.10), pain in throat/neck (OR 2.24) and pain intensity (OR 0.85). Predictors associated with contacting EMS as FMC were history of MI (OR 2.18), atrial fibrillation (OR 3.81), abdominal pain (OR 0.35) and believing the symptoms originating from the heart (OR 1.60). Symptom onset to diagnosis time was significantly longer when turning to the SHD instead of the EMS as FMC (1:59 vs 1:21 h, p<0.001).CONCLUSIONS: Using other forms of contacts than EMS, significantly prolong delay times, and could adversely affect patient prognosis. Nevertheless, having the opportunity to call the SHD might also, in some instances, lower the threshold for taking contact with the healthcare system, and thus lowers the number that would otherwise have delayed even longer.
