Abstract Background Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide. The effective management of patients with AMI is directly linked to time, and approximately one-half of the deaths attributed to AMI occur from cardiac arrest in the out-of-hospital setting, reinforcing the importance of the prehospital care. Contemporary data remain particularly lacking about the use of prehospital care in the setting of AMI, particularly from the more generalizable perspective of a community-based investigation, as well as information about the hospital outcomes of patients transported by ambulance. Purpose To assess the impact the implementation of a nationwide ambulance service (Serviço de Atendimento Médico de Urgência, SAMU) on AMI mortality and number of hospitalizations, in the state of Minas Gerais, Brazil. Methods Retrospective, ecological study, which assessed data from the Brazilian Universal Health System (SUS), from all 853 municipalities of Minas Gerais, from 2008 to 2016. SAMU implementation dates were obtained from the state government and SAMU local coordinators. Data on the population of each municipality was obtained from Instituto Brasileiro de Geografia e Estatística (IBGE), the Brazilian official demographic institute. Excessive skewness of general and in-hospital mortality rates were smoothed using the Empirical Bayes method The relationship between SAMU care in each municipality and the mortality due to AMI in the general population, in-hospital mortality and number of hospitalizations for AMI was assessed using the Poisson hierarchical model, and the analyzed rates were corrected by the age structure and detrended by seasonal influences. Results AMI mortality rates showed a decreasing tendency throughout the study, on average 2% per year, and seasonal variation, being higher during winter months. Age-corrected AMI in-hospital mortality also showed a decreasing trend, from 13.81% in 2008 to 11.43% in 2016. SAMU implementation was associated with decreased AMI mortality (odds ratio [OR]=0.967, 95% confidence interval [CI] 0.936–0.998) and AMI in-hospital mortality (OR=0.914, 95% CI 0.845–0.986) with no relation with the number of hospitalizations (OR 1.003, 95% CI 0.927–1.083). There was no seasonal variation in the number of AMI hospitalizations. Conclusion SAMU implementation was related to a modest but significant decrease in AMI in-hospital mortality. This finding reinforces the main role of prehospital care in AMI care and reinforces the need for investment in improving the service throughout the country.

Abstract Background Ischemic heart disease (IHD) is the most common cause of death with an increasing frequency worldwide. It accounts for approximately 20% of all deaths in Europe and the United States of America. Approximately 1/3 of the IHD patients present with sudden cardiac death. The acute presentation of IHD myocardial infarction (MI) is a life-threatening, serious health problem, which causes substantially morbidity and mortality. It is well established that the onset of MI follows a circadian and seasonal periodicity. Seasonal variation regarding the incidence and the short-term mortality of acute MI was frequently reported, but data about sex-specific differences are sparse. Purpose Thus, our objectives were to investigate seasonal variations of myocardial infarction. Methods We analyzed the impact of seasons on incidence and in-hospital mortality of patients with acute MI in Germany from 2005 to 2015. We included all MI patients (ICD code I21) with an acute MI (, but not those MI patients with a recurrent event in the first 28 days after a previous MI (ICD code I22)), who were hospitalized in Germany between 2005 and 2015, in this analysis (source: RDC of the Federal Statistical Office and the Statistical Offices of the federal states, DRG Statistics 2005–2015, own calculations). Results The nationwide sample comprised 3,008,188 hospitalizations of patients with MI (2005–2015). The annual incidence was 334.7 per 100.000 population. Incidence inclined from 316.3 to 341.6 per 100.000 population per year (β 0.17 [0.10 to 0.24], P<0.001), while in-hospital mortality rate decreased from 14.1% to 11.3% (β −0.29 [−0.30 to −0.28, P<0.001). Overall, 377,028 (12.5%) patients died in-hospital. Seasonal variation of both incidence and in-hospital mortality were of substantial magnitude. Seasonal incidence (86.1 vs. 79.0 per 100.000 population per year, P<0.001) and in-hospital mortality (13.2% vs. 12.1%, P<0.001) were higher in the winter than in the summer saeson. Risk to die in winter was elevated (OR 1.080 (95% CI 1.069–1.091), P<0.001) compared to summer season independently of sex, age and comorbidities. Reperfusion treatment with drug eluting stents and coronary artery bypass graft were more often used in summer. We observed sex-specific differences regarding the seasonal variation of in-hospital mortality: males showed lowest mortality in summer, while females during fall. Low temperature dependency of mortality seems more pronounced in males. Conclusions Incidence of acute MI increased 2005–2015, while in-hospital mortality rate decreased. Seasonal variations of incidence and in-hospital mortality were of substantial magnitude with lowest incidence and lowest mortality in the summer season. Additionally, we observed sex-specific differences regarding the seasonal variation of the in-hospital mortality.

BackgroundCardiovascular diseases are the second most common cause of mortality among cancer survivors, after death from cancer. We sought to assess the impact of cancer on the short-term outcomes of acute myocardial infarction (AMI), by analysing data obtained from a large-scale database.MethodsThis study was based on the Diagnosis Procedure Combination database in the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination. We identified patients who were hospitalised for primary AMI between April 2012 and March 2017. Propensity Score (PS) was estimated with logistic regression model, with cancer as the dependent variable and 21 clinically relevant covariates. The main outcome was in-hospital mortality.ResultsWe split 1 52 208 patients into two groups with or without cancer. Patients with cancer tended to be older (cancer group 73±11 years vs non-cancer group 68±13 years) and had smaller body mass index (cancer group 22.8±3.6 vs non-cancer 23.9±4.3). More patients in the non-cancer group had hypertension or dyslipidaemia than their cancer group counterparts. The non-cancer group also had a higher rate of percutaneous coronary intervention (cancer 92.6% vs non-cancer 95.2%). Patients with cancer had a higher 30-day mortality (cancer 6.0% vs non-cancer 5.3%) and total mortality (cancer 8.1% vs non-cancer 6.1%) rate, but this was statistically insignificant after PS matching.ConclusionCancer did not significantly impact short-term in-hospital mortality rates after hospitalisation for primary AMI.

Purpose: Several studies have reported gender difference in presentation, management and outcome in patients with acute myocardial infarction (AMI). In this study, we focused the impact of age on gender difference in mortality after AMI. Methods: Between July 2012 and March 2014, 3283 patients were admitted to the 28 hospitals participating to the J-MINUET group within 48 hours after the onset of AMI. AMI was diagnosed by universal definition (type 1 or type 2). Patients were divided into 5 strata according to their age: those with age <55 years, 55-64 years, 65-74 years, 75-84 years and ≥85 years. Results: There were 813 women (24.8%). Women were significantly older than men (74.5±11.8 years vs 66.6±12.3 years, P<0.001). Women had longer time from onset to admission, more NSTEMI, atypical symptom other than chest pain, Killip class ≥2, CKD and type 2 MI. They also had less diabetes and current smoking habits. Although most of the patients received urgent angiography (93.1%), it was less frequent in women (90.4% vs 94.0%, P<0.001). Among patients who underwent primary PCI (85.1%), achievement of final TIMI-3 flow was similar (91.2% vs 92.0%, P=0.53). In-hospital mortality was significantly higher in women than men (9.6% vs 5.5%, P<0.001). When patients were stratified according to their age, there was a liner increase in the prevalence of women as age advanced: 10.6% in <55 years, 15.1% in 55-64 years, 19.8% in 65-74 years, 35.6% in 75-84 years and 53.6% in ≥85 years (P<0.001). There was no significant gender difference in mortality in each stratum (Figure). Multivariate analysis showed that women was no more an independent predictor of death after adjusting age (OR 1.29, 95%CI 0.95-1.75, P=0.10), or age and other variables (OR 1.19, 95%CI 0.79-1.76, P=0.40). Conclusions: Women had higher in-hospital mortality than men after AMI even in the contemporary troponin era. However, their high mortality was mostly explained by their advanced age.

Abstract BackgroundThe prognostic role of hyperglycemia in patients with myocardial infarction and obstructive coronary arteries (MIOCA) is acknowledged, while data on non-obstructive coronary arteries (MINOCA) are still lacking. Recently, we demonstrated that admission stress-hyperglycemia (aHGL) was associated with a larger infarct size and inflammatory response in MIOCA, while no differences were observed in MINOCA. We aim to investigate the impact of aHGL on short and long-term outcomes in MIOCA and MINOCA patients.MethodsMulticenter, population-based, cohort study of the prospective registry, designed to evaluate the prognostic information of patients admitted with acute myocardial infarction to S. Orsola-Malpighi and Maggiore Hospitals of Bologna metropolitan area. Among 2704 patients enrolled from 2016 to 2020, 2431 patients were classified according to the presence of aHGL (defined as admission glucose level ≥ 140mg/dL) and AMI phenotype (MIOCA/MINOCA): no-aHGL (n = 1321), aHGL (n = 877) in MIOCA and no-aHGL (n = 195), aHGL (n = 38) in MINOCA. Short-term outcomes included in-hospital death and arrhythmias. Long-term outcomes were all-cause and cardiovascular mortality.ResultsaHGL was associated with a higher in-hospital arrhythmic burden in MINOCA and MIOCA, with increased in-hospital mortality only in MIOCA. After adjusting for age, gender, hypertension, Killip class and AMI phenotypes, aHGL predicted higher in-hospital mortality in non-diabetic (HR = 4.2; 95% CI 1.9–9.5, p = 0.001) and diabetic patients (HR = 3.5, 95% CI 1.5–8.2, p = 0.003). During long-term follow-up, aHGL was associated with 2-fold increased mortality in MIOCA and a 4-fold increase in MINOCA (p = 0.032 and p = 0.016). Kaplan Meier 3-year survival of non-hyperglycemic patients was greater than in aHGL patients for both groups. No differences in survival were found between hyperglycemic MIOCA and MINOCA patients. After adjusting for age, gender, hypertension, smoking, LVEF, STEMI/NSTEMI and AMI phenotypes (MIOCA/MINOCA), aHGL predicted higher long-term mortality.ConclusionsaHGL was identified as a strong predictor of adverse short- and long-term outcomes in both MIOCA and MINOCA, regardless of diabetes. aHGL should be considered a high-risk prognostic marker in all AMI patients, independently of the underlying coronary anatomy.Trial Registrationdata were part of the ongoing observational study AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation.

Abstract Background It is known that low diastolic blood pressure (DBP) is associated with long-term cardiovascular events after acute myocardial infarction (AMI). However, the impact of low diastolic blood pressure on short-term outcome has not yet been well investigated. Methods and results We included 15,208 patients who were hospitalized for AMI and registered in the Tokyo CCU network registry between 2013 and 2016. Thirty-day in-hospital mortality rate was 4.8% (728/15,208). To assess the relationship between DBP at the time of admission and 30-day mortality non-linearly, spline regression model was applied with the stratification of the cohort according to tercile of systolic blood pressure (SBP, low:≤122 mmHg, intermediate:123–148 mmHg, high:≥149 mmHg) and J-curve phenomenon was observed in the low and high SBP groups. In multivariate logistic regression analysis, adjusted odds ratio of the lowest quintile of DBP (≤64 mmHg) was 1.65 (95% CI:1.02–2.66) in low SBP group and 4.55 (95% CI:1.72–12.00) in high SBP group. Conclusion Low DBP was associated with increased 30-day in-hospital mortality rate after AMI even in patients with high SBP. Funding Acknowledgement Type of funding source: None

Abstract Background Higher mortality rates in patients admitted for an acute myocardial infarction during weekends has been recently confirmed. Differences in staffing and in lower rates of early reperfusion therapy are thought to affect outcomes of these patients particularly of those presenting with ST segment elevation. Patients affected by Takotsubo cardiomyopathy may present themselves mimicking those affected by heart attack and are frequently admitted with supposed diagnosis of acute coronary syndrome. No data is available about influence on mortality in relation to the time of admission among patients with Takotsubo cardiomyopathy. Rationale The aim of this study is to assess the effect on mortality due to admission during weekend among patients discharged with diagnosis of Takotsubo cardiomyopathy. Methods We retrieved administrative data about every admission to National Healthcare System hospitals in Italy between 2009 and 2017 with final diagnosis of Takotsubo cardiomyopathy according to ICD9-CM classification of diseases (code 429.83). Date of admission was used to determine the weekend (Saturday and Sunday) or weekdays exposure (Monday to Friday). The primary outcome was in-hospital mortality. Demographical characteristics of patients (age and sex) were included in a multivariate logistic regression analysis. We also analyzed the impact of weekend admission on time to coronary angiography and on length of hospital staying. Analyses were performed using Stata 13.0. Results A total of 10,861 Takotsubo admissions were identified. Mean age was 70.7 years and 91.7% were women. The in-hospital mortality was 2.21%. We found that there was no significant increase in the risk of death among patients admitted during weekends (OR 1.07; 95% CI 0.77–1.44). The variability explained by the model was of 4.2% (pseudo R-squared 0.042). Men have a higher risk of mortality as compared to women (OR 2.37, 95% C.I 1.69–3.33). Patients admitted during weekend tends to stay in hospital longer, but they do not seem to wait more days to get a coronary angiography. Conclusions At variance with patients with ST elevated acute myocardial infarction, subjects admitted during weekends for Takotsubo cardiomyopathy did not show an excess of in-hospital mortality in comparison to those admitted during week days.

Objectives To investigate a possible weekend effect in the in-hospital mortality rate for acute myocardial infarction in Portugal, and whether the delay in invasive intervention contributes to this effect. Methods Data from the National 2011–2015 Diagnostic-Related-Group databases were analysed. The focus was on adult patients admitted via the emergency department and with the primary diagnosis of acute myocardial infarction. Patients were grouped according to ST-elevation myocardial infarction and non-ST-elevation myocardial infarction episodes. We employed multivariable logistic regressions to determine the association between weekend admission and in-hospital mortality, controlling for episode complexity (through a severity index and acute comorbidities), demographic characteristics and hospital identifications. The association between the probability of a prompt surgery (within one day) and the day of admission was investigated to explore the possible delay of care delivery for patients admitted during weekends. Results Our results indicate that in-hospital mortality rates were not significantly higher for weekend admissions than for weekday admissions in both ST-elevation myocardial infarction (STEMI) and non-STEMI episodes. This result is robust to the inclusion of a number of potential confounding mechanisms. Patients admitted on weekends had lower probabilities of undergoing invasive cardiac surgery within the day after admission, but delay in care delivery during the weekend was not associated with worse outcomes in terms of in-hospital mortality. Conclusions There is no evidence for the existence of a weekend effect due to admission for acute myocardial infarction in Portugal, in both STEMI and non-STEMI episodes.
