Acute Myocardial Infarction Death Research Articles

Multitask Interactive Attention Learning Model Based on Hand Images for Assisting Chinese Medicine in Predicting Myocardial Infarction.

Acute myocardial infarction (AMI) is one of the most serious and dangerous cardiovascular diseases. In recent years, the number of patients around the world has been increasing significantly, among which people under the age of 45 have become the high-risk group for sudden death of AMI. AMI occurs quickly and does not show obvious symptoms before onset. In addition, postonset clinical testing is also a complex and invasive test, which may cause some postoperative complications. Therefore, it is necessary to propose a noninvasive and convenient auxiliary diagnostic method. In traditional Chinese medicine (TCM), it is an effective auxiliary diagnostic strategy to complete the disease diagnosis through some body surface features. It is helpful to observe whether the palmar thenar undergoes hypertrophy and whether the metacarpophalangeal joint is swelling in detecting acute myocardial infarction. Combined with deep learning, we propose a depth model based on traditional palm image (MTIALM), which can help doctors of traditional Chinese medicine to predict myocardial infarction. By building the shared network, the model learns information that covers all the tasks. In addition, task-specific attention branch networks are built to simultaneously detect the symptoms of different parts of the palm. The information interaction module (IIM) is proposed to further integrate the information between task branches to ensure that the model learns as many features as possible. Experimental results show that the accuracy of our model in the detection of metacarpophalangeal joints and palmar thenar is 83.16% and 84.15%, respectively, which are significantly improved compared with the traditional classification methods.

Predictive Factors of Left Ventricle (LV) Dysfunction in Acute Myocardial Infarction (AMI): A Prospective Study

Left ventricular dysfunction (LV dysfunction) complicating myocardial infarction is common. Among patients with acute myocardial infarction (AMI), a strong relationship between the degree of LV dysfunction and mortality has been demonstrated. LV dysfunction is known to be a strong predictor of death in AMI with important implications for prognosis and treatment. The identification of patients at risk of developing LV dysfunction after AMI is relevant in the sense that it allows early and optimal management of heart failure for better quality of life. This prospective study of 75 cases of AMI complicated or not with LV dysfunction, hospitalized in the intensive care unit of the Mohammed V military training hospital in Rabat, covering a period of 6 months, aims to determine the predictive factors of LV dysfunction after an AMI in a Moroccan population group. It was found that male gender, delay in management, heart rate on admission, electrical territory, and the existence of crackling sounds on lungs at admission are predisposing factors for left ventricular systolic dysfunction. However, dyslipidemia is a protective factor. Early management of these patients would reduce the risk of reinfarction and death.

In this context, feasibility of Off-Clamp PN is controversial. We report surgical technique, perioperative, oncologic, and mid-term functional outcomes of a single center purely off-clamp robotic PN series for totally endophytic masses. METHODS: The case of a 73-yr old male with a 3.3 cm endophytic left renal tumor was reported. Surgical steps were highlighted, focusing on ICG guide to identify the mass and margins scoring, simultaneous use of two suction devices combining irrigation and suction to maintain a bloodless and clear operative field, enucleative strategy and finally a selective renorraphy to avoid any unintentional injury to hilar branches of main vessels. Potential use of near infrared fluorescence was showed, including intravenous injection to ensure maximal preservation of healthy and functioning renal parenchyma and preoperative transarterial delivery to optimize tumor identification and resection strategy. Baseline, perioperative, oncologic and functional data were reported. RESULTS: Between January 2013 and December 2020, 56 consecutive patients with totally endophytic renal masses were treated. Median tumor diameter was 3 cm, both median PADUA and RENAL scores were 10. Median baseline eGFR was 86.4 ml/min. Median operative time was 82 minutes, and no conversion to On-clamp procedure or Radical nephrectomy was necessary in any case. Median hospital stay was 3 days. Low grade Clavien complications occurred in two patients (3.6%), high grade Clavien complication were observed in four patients (7.1%), of which one patient underwent selective arterial embolization, for post-operative bleeding, in first post-operative day; two patients underwent ureteral stent placement for urinary fistula, resolved at one-month evaluation. At thirty-day evaluation, we reported one death for acute myocardial infarction. One third of cases (32.2%) displayed a benign histotype at the final pathology.Positive surgical margins were detected in one case; 2-yr recurrence-free, cancer specific and overall survival rates were 100, 100 and 98.2 %, respectively. At a median follow-up of 24 months, newly onset of CKD stage 3b occurred in 1 single case. Median eGFR at discharge was 75 ml/min, with a median eGFR percent decrease of 10.9 %. At last follow-up median eGFR was 77 ml/min, with a median eGFR percent decrease of 5.5%. Trifecta, defined as combination of negative surgical margins, no perioperative ³3 Clavien complications and absence of significant eGFR decline (>30%), was achieved in 91% of patients. CONCLUSIONS: Purely off-clamp Robotic PN proved to be a feasible and safe surgical approach, even in totally endophytic renal tumors, providing favorable perioperative complications rate, excellent oncological outcomes, and negligible impact on renal function at mid-term follow-up. According to recent Literature, these complex cases should be considered for selective referral to high volume centers.

Treinamento de Não-Cardiologistas pode Melhorar os Resultados do Tratamento de Infarto Agudo do Miocárdio com Supra de ST

ResumoFundamento De acordo com a Organização Mundial da Saúde, países emergentes terão um crescimento considerável no número de ataques cardíacos e mortes relacionadas. Um dos principais problemas médicos no Brasil é a mortalidade causada por infarto agudo do miocárdio com supra de ST (IAMCSST). A Sociedade de Cardiologia do Estado de São Paulo nunca treinou não-cardiologistas para atendimentos de emergência. Os pacientes normalmente buscam ajuda em prontos-socorros, em vez de chamar a ambulância.Objetivo Nosso objetivo foi reduzir as taxas de mortalidade hospitalar causada por infarto agudo do miocárdio ao treinar profissionais da emergência na cidade de São Paulo.Métodos Utilizamos um programa de treinamento para as equipes de cinco hospitais com > 100 pacientes internados com IAMCSST por ano, e pelo menos 15% de mortes hospitalares relacionadas ao IAMCSST. Realizamos treinamentos online, organizamos de dois a quatro eventos para até 400 participantes, fizemos folders e panfletos informativos. A análise estatística utilizou o teste para comparação de duas proporções, com p <0,05.Resultados Quase 200 médicos e 350 enfermeiros participaram de pelo menos um treinamento de maio de 2010 até dezembro de 2013. Inicialmente, muitos médicos da emergência não reconheciam um infarto agudo do miocárdio no eletrocardiograma, mas a tele-ecocardiografia é usada em alguns departamentos da emergência para determinar o diagnóstico. A taxa de mortalidade nos cinco hospitais caiu de 25,6%, em 2009, para 18,2%, em 2010 (p=0,005). Depois da conclusão do período de treinamento, as mortes relacionadas ao IAMCSST em todos os hospitais públicos de São Paulo diminuíram de 14,31%, em 2009, para 11,25%, em 2014 (p<0,0001).Conclusão Mesmo programas simplificados de treinamento de pessoal da emergência pode reduzir muito as taxas de morte por infarto agudo do miocárdio em países em desenvolvimento.

Prognostic Value of Residual Coronary Artery Lesions on the SYNTAX Scale in Patients with Acute Myocardial Infarction without SТ Segment Elevation in the Mid-Term Period.

Aim To study the effect of residual coronary injury after a percutaneous coronary intervention (PCI), as evaluated with the SYNTAX scale (residual SYNTAX score, RSS), on the mid-term prognosis for patients with non-ST elevation acute myocardial infarction (NSTEMI) and also to determine threshold RSS values for patients at high and low risk of adverse cardiac events.Material and methods A single-center, retrospective study was performed. From 421 patients with NSTEMI after PCI with stenting, 169 patients were selected who originally had multivessel coronary disease and who had undergone a repeated inpatient examination, including mid-term (11.7±3.0 mos.) coronary angiography. The endpoints were recurrent clinical manifestations of angina, repeat revascularization (RR), unstable angina (UA), recurrent acute myocardial infarction (AMI), cardiac death, and also a composite endpoint (major adverse cardiac events, MACE) that included UA, recurrent AMI, and cardiac death. After revealing a significant direct correlation between RSS and the probability of recurrent AMI, UA, MACE, or RR (p &lt;0.05) using the ROC analysis, we have established threshold RSS values that divided patients into groups with high and low risk of the cardiac events listed above.Results For a significantly high risk of recurrent AMI (area under the curve, AUC 0.79±0.05; 95 % confidence interval, CI 0.68-0.89; р=0.048), the threshold RSS score was 8 (sensitivity 100 %, specificity 70.9 %). For UA and MACE, the RSS scores were both 3 (AUC 0.68±0.5; 95 % CI 0.58-0.79; p=0.005 and AUC 0.71±0.05; 95 % CI 0.61-0.8; p=0.001, respectively). The probability of UA during the observation period with RSS &gt;3 was 4.07 times higher and that of MACE was 5.23 times higher than with RSS&lt;3 (95 % CI 1.44-11.49; р=0.01 and 95 % CI 1.88-14.53; р=0.001, respectively).Conclusion The study demonstrated a significant, direct correlation between the RSS and the risk of adverse cardiac events in patients with NSTEMI during one year of observation. Specific threshold values were obtained, which may help in choosing both the extent of revascularization and the tactics for postoperative management of patients.

Mortality due to acute myocardial infarction in the Silesian Voivodship (Poland) in 2009-2014.

According to the Organization for Economic Cooperation and Development (OECD) data, 13% of deaths recorded in the European Union in 2010 were related to coronary heart disease. The Polish Central Statistical Office data show that cardiovascular mortality in 2014 was at the level of 100.1/100 000 general population. The aim of the study was to assess the current burden of deaths due to acute myocardial infarction (AMI) with the assessment of temporal and spatial variability in the Silesian Voivodeship, Poland. Depersonalized data obtained from the Silesian Voivodeship Branch of the National Health Fund of Poland, based in Katowice, were used as the study material. The death rate due to acute or subsequent myocardial infarction in each of the subregions of the Silesian Voivodeship was standardized to the European Standard Population 2013. The analyses of the annual AMI death rate for 2009-2014 were performed and assigned to all the subregions of the Silesian Voivodeship, according to the patients' domicile. In this study, 37.7% of the patients (N = 20 806) were females, and 30 142 healthcare services were granted to them, accounting for 36.64% of all services provided to all patients. The average patient's age during the service provision was 66±12 years, with women being about 6.5 years older than men (70±12 years vs. 64±11 years, respectively). The standardized death rate (SDR) values in each of the 8 subregions of the Silesian Voivodeship were analyzed. In 2009-2014, a substantial decrease in the SDR was noted in 7 of them, except for the Sosnowiec subregion in which an increase in the average annual SDR value was observed. Moreover, its values were the highest in the whole Silesian Voivodeship. The obtained results confirmed the spatial variability of mortality due to AMI in the study region. The worst situation was observed in the Sosnowiec subregion in which the number of specific deaths continuously increased, probably due to the limited availability of cardiological and invasive cardiology treatments or adverse health conditions.

Diagnostic Application of Postmortem Cardiac Troponin I Pericardial Fluid/Serum Ratio in Sudden Cardiac Death

In approximately 5% of unexpected deaths, establishing a conclusive diagnosis exclusively on the basis of anatomo-pathological findings in a classic autopsy is difficult. Postmortem biomarkers have been actively investigated as complementary indicators to help to reach valid conclusions about the circumstances of death. Several studies propose either the pericardial fluid or peripheral veins as a location for troponin determination, but the optimum sampling site is still a matter of debate. Our objective was to evaluate the association between the ratio of troponin values in the pericardial fluid and serum (determined postmortem) and the diagnosis of acute myocardial infarction (AMI) in the context of sudden cardiac death. We included 175 forensic cases. Two groups were established: AMI deaths (48; 27.4%) and the control group (127; 72.6%). The cardiac Troponin I (cTnI) values in the pericardial fluid and the troponin ratio were found to be associated with the cause of death. Univariate regression analyses showed that both age and the cTnI ratio were significantly associated with the diagnosis of AMI death. In a multivariate analysis, adjusting for confounding factors, the age and cTnI ratio were independent predictors of death from myocardial infarction. We performed a receiver operating characteristic (ROC) curve for the cTnI ratio for AMI death and selected a cut-off point. Our biomarker was found to be a valuable and highly effective tool for use in the forensic field as a complementary method to facilitate diagnosis in nonconclusive autopsies.

Soluble triggering receptor expressed on myeloid cells-1 is a marker of organ injuries in cardiogenic shock: results from the CardShock Study.

Optimal outcome after cardiogenic shock (CS) depends on a coordinated healing response in which both debris removal and extracellular matrix tissue repair play a crucial role. Excessive inflammation can perpetuate a vicious circle, positioning leucocytes as central protagonists and potential therapeutic targets. High levels of circulating Triggering Receptor Expressed on Myeloid cells-1 (TREM-1), were associated with death in acute myocardial infarction confirming excessive inflammation as determinant of bad outcome. The present study aims to describe the association of soluble TREM-1 with 90-day mortality and with various organ injuries in patients with CS. This is a post-hoc study of CardShock, a prospective, multicenter study assessing the clinical presentation and management in patients with CS. At the time of this study, 87 patients had available plasma samples at either baseline, and/or 48h and/or 96-120h for soluble TREM-1 (sTREM-1) measurements. Plasma concentration of sTREM-1 was higher in 90-day non-survivors than survivors at baseline [median: 1392 IQR: (724-2128) vs. 621 (525-1233) pg/mL, p = 0.008), 48h (p = 0.019) and 96-120h (p = 0.029). The highest tertile of sTREM-1 at baseline (threshold: 1347pg/mL) was associated with 90-day mortality with an unadjusted HR 3.08 CI 95% (1.48-6.42). sTREM-1 at baseline was not associated to hemodynamic parameters (heart rate, blood pressure, use of vasopressors or inotropes) but rather with organ injury markers: renal (estimated glomerular filtration rate, p = 0.0002), endothelial (bio-adrenomedullin, p = 0.018), myocardial (Suppression of Tumourigenicity 2, p = 0.002) or hepatic (bilirubin, p = 0.008). In CS patients TREM-1 pathway is highly activated and gives an early prediction of vital organ injuries and outcome.

Epidemiological trends in mortality, event rates and case fatality of acute myocardial infarction from 2004 to 2015: results from the KORA MI registry

Aim This study examines epidemiological trends of acute myocardial infarction (AMI) in Germany from 2004–2015 across different age groups, using data of the population-based KORA myocardial infarction registry. Methods Annual age-standardised, age-group- and sex-specific mortality and event rates (incident and recurrent) per 100,000 population as well as 28-day case fatality were calculated from all registered cases of AMI and coronary heart disease deaths in 25–74-year-olds from 2004–2015 and 75–84-year-olds from 2009–2015. Average annual percentage changes (AAPC) were calculated by joinpoint regression. Results Mortality rates declined considerably among the elderly (75–84 years), in men by –6.0% annually, due to declines of case fatality by –3.0% and incidence rate by 3.4% and in women by –10.0%, driven by declines in incidence (–9.1%) and recurrence rate (–4.9%). Significant mortality declines also occurred in males, 65–74 years of age (AAPC –3.8%). Among the age groups 25–54 years and 55–64 years, there was no substantial decline in mortality, event rates or case fatality except for a decline of incidence rate in 55–64-year-old men (AAPC –1.8%). Conclusion Inhomogeneous AMI trends across age-groups indicate progress in prevention and treatment for the population >64 years, while among <55-year-olds, we found no significant trend in AMI morbidity and mortality. KEY MESSAGES Age standardised AMI mortality continued to decline from 2009 to 2015 in the study region. Declines in AMI mortality were driven by declines in event rates (both incidence and recurrence rates) and case fatality. AMI trends were inconsistent across different age groups with the strongest declines in mortality and event rates among the elderly population (75–84 years of age).

Unmet needs for emergency care and prevention of prehospital death in acute myocardial infarction

Introduction: Percutaneous coronary intervention (PCI) has successfully reduced the mortality of patients with acute myocardial infarction (AMI). However, patients with out-of-hospital cardiac arrest have high mortality, which is difficult to control by hospital staff. In this study, we investigated the prevalence of prehospital death (PHD) in patients with AMI. Furthermore, we investigated the risk factors associated with 30-day mortality in patients with AMI who survived PHD.Methods: We investigated the prevalence of PHD using data from the Yamagata AMI registry and from death certification of the entire Yamagata Prefecture in Japan between 2010 and 2015. Furthermore, we investigated the risk factors for 30-day mortality in patients who survived PHD, using data from the Yamagata AMI registry from 1993 to 2015. AMI was identified by the International Classification of Diseases, 10th revision code I21.Results: Out of the 6984 patients with AMI, 3771 patients had PHD. Patients with PHD were older and more likely to be women than those without PHD. More PHD occurred in winter and spring than in summer or autumn. Multivariate regression analysis showed that age, female sex, and winter onset were independently associated with PHD.We also investigated the risk factors associated with 30-day mortality in 9675 patients who survived PHD. The rate of PCI was remarkably lower in patients with acute death than in those without acute death. Multivariate regression analysis showed that age, anterior infarction, estimated glomerular filtration rate, Killip class, and PCI were independently associated with 30-day mortality after adjusting for confounding factors.Conclusion: Approximately half of the patients with AMI died before they could reach the destination hospital. Although emergency PCI is the most important factor in reducing 30-day mortality in patients with AMI, attempts to reduce patient delay and system delay are possibly needed to further reduce PHD.

Superior Short-term Patency of Stents Over Balloons in Infrapopliteal Artery Disease

Cardiogenic shock remains the leading cause of in-hospital death in acute myocardial infarction (AMI). Because of temporary changes in management of cardiogenic shock with widespread implementation of early revascularization along with increasing attention to the use of mechanical circulatory devices, complete and longitudinal data are important in this subject. The objective of this study was to examine temporal trends of first-time hospitalization, management, and short-term mortality for patients with AMI-related cardiogenic shock (AMICS).Using nationwide medical registries, we identified patients hospitalized with first-time AMI and cardiogenic shock from January 1, 2005, through December 31, 2017. We calculated annual incidence proportions of AMICS. Thirty-day mortality was estimated with use of Kaplan-Meier estimator comparing AMICS and AMI-only patients. Multivariable Cox regression models were used to assess mortality rate ratios.We included 101,834 AMI patients of whom 7,040 (7%) had AMICS. The median age was 72 (interquartile range: 62-80) for AMICS and 69 (interquartile range: 58-79) for AMI-only patients. The gender composition was similar between AMICS and AMI-only patients (male: 64% vs 63%). The annual incidence proportion of AMICS decreased slightly over time (2005: 7.0% vs 2017: 6.1%, P for trend < .0001). In AMICS, use of coronary angiography increased between 2005 and 2017 from 48% to 71%, as did use of left ventricular assist device (1% vs 10%) and norepinephrine (30% to 70%). In contrast, use of intra-aortic balloon pump (14% vs 1%) and dopamine (34% vs 20%) decreased. Thirty-day mortality for AMICS patients was 60% (95% CI: 59-61) and substantially higher than the 8% (95% CI: 7.8-8.2) for AMI-only patients (mortality rate ratio: 11.4, 95% CI: 10.9-11.8). Over time, the mortality decreased after AMICS (2005: 68% to 2017: 57%, P for temporal change in adjusted analysis < .0001).We observed a slight decrease in AMICS hospitalization over time with changing practice patterns. Thirty-day mortality was markedly higher for patients with AMICS compared with AMI only, yet our results suggest improved 30-day survival over time after AMICS.

A single high-sensitivity cardiac troponin T compared to the HEART score for a rapid rule-out of acute myocardial infarction at a prehospital emergency clinic

Abstract Background Patients presenting with acute chest pain outside of hospitals represent a diagnostic challenge. Purpose We aimed to validate whether a single high-sensitivity cardiac troponin T (hs-cTnT) safely can rule out acute myocardial infarction (AMI) in a primary care emergency setting. In addition, we aimed to investigate if the hs-HEART (History, Electrocardiogram (ECG), Age, Risk factors, and hs-Troponin) score would add valuable diagnostic information. Methods This is a secondary analysis from a prospective diagnostic study, including 1711 patients with acute non-specific chest pain presenting to a primary care emergency clinic from November 2016 to October 2018. The European Society of Cardiology (ESC) 0/1-hour algorithm triages patients towards direct rule-out if the 0-hour hs-cTnT is below 5 ng/L, combined with a normal ECG and a 3-hour symptom duration. The hs-HEART score (0–10 points) was calculated retrospectively, and a score ≤3 points was considered low-risk. In addition, a modified hs-HEART score, with more comparable hs-cTnT cut-off values, was applied. The primary endpoint was AMI during the index episode; the secondary the 90-day incidence of AMI (including index) and all-cause death. Results Among 1711 patients, 61 (3.6%) had an AMI, and 525 (30.7%) were assigned towards direct rule-out. With no AMIs in this group, the rule-out safety was high (negative predictive value (NPV) and sensitivity 100%). The hs-HEART score triaged more patients (n=966) as low-risk, but missed six AMIs (NPV 99.4% and sensitivity 90.2%). The modified hs-HEART score (n=707, AMI=3) increased the low-risk sensitivity to 95.1%. The 90-day incidence of AMI and all-cause death in the direct rule-out, low-risk hs-HEART, and modified hs-HEART group, were 0.0%, 0.7%, and 0.4%, respectively. Conclusions The ESC direct rule-out approach, with a single hs-cTnT below 5 ng/L, combined with a normal ECG, and a 3-hour symptom duration, is superior to the two hs-HEART scores in ruling out AMI in a primary care emergency setting.

Value of heart rate variability on dynamic electrocardiogram in predicting ventricular fibrillation in elderly acute myocardial infarction patients.

Ventricular fibrillation (VF) is the main cause of sudden death in Acute myocardial infarction (AMI) patients. Identifying arrhythmia as early as possible is of great significance in improving prognosis of AMI patients. The article is aimed at exploring the predictive value of heart rate variability (HRV) of dynamic electrocardiogram (DCG) in VF of elderly AMI patients. A total of 122 elderly AMI patients were enrolled as the research objects. They were divided into VF group and simple AMI group (AMI group). All underwent DCG test after admission. The basic data of patients were compared. HRV of DCG was observed. The predictive value of HRV of DCG in VF of elderly AMI patients was evaluated by receiver operating characteristic (ROC) curves. The ratio of Killip at grade II-III, activity of creatine kinase-MB (CK-MB), standard deviation of all R-R intervals (SDNN), the standard deviation of the R-R intervals (SDANN), root-mean-square of the successive differences of normal RR intervals (rMSSD) and percentage of NN50 in the total number of NN intervals PNN50 (PNN50%)]in VF group were higher than those in AMI group (P<0.05). The area under the ROC curves (AUC)and cut-off values of SDNN, SDANN, rMSSD and PNN50% were (0.773, 0.761, 0.800, 0.819) and (135.675, 106.850, 33.570, 14.080), respectively. HRV of DCG is of certain predictive value for VF in the elderly with AMI, which is expected to be an auxiliary diagnosis method of VF.

Trends in first-time hospitalization, management, and short-term mortality in acute myocardial infarction–related cardiogenic shock from 2005 to 2017: A nationwide cohort study

Cardiogenic shock remains the leading cause of in-hospital death in acute myocardial infarction (AMI). Because of temporary changes in management of cardiogenic shock with widespread implementation of early revascularization along with increasing attention to the use of mechanical circulatory devices, complete and longitudinal data are important in this subject. The objective of this study was to examine temporal trends of first-time hospitalization, management, and short-term mortality for patients with AMI-related cardiogenic shock (AMICS). Using nationwide medical registries, we identified patients hospitalized with first-time AMI and cardiogenic shock from January 1, 2005, through December 31, 2017. We calculated annual incidence proportions of AMICS. Thirty-day mortality was estimated with use of Kaplan-Meier estimator comparing AMICS and AMI-only patients. Multivariable Cox regression models were used to assess mortality rate ratios. We included 101,834 AMI patients of whom 7,040 (7%) had AMICS. The median age was 72 (interquartile range: 62-80) for AMICS and 69 (interquartile range: 58-79) for AMI-only patients. The gender composition was similar between AMICS and AMI-only patients (male: 64% vs 63%). The annual incidence proportion of AMICS decreased slightly over time (2005: 7.0% vs 2017: 6.1%, P for trend < .0001). In AMICS, use of coronary angiography increased between 2005 and 2017 from 48% to 71%, as did use of left ventricular assist device (1% vs 10%) and norepinephrine (30% to 70%). In contrast, use of intra-aortic balloon pump (14% vs 1%) and dopamine (34% vs 20%) decreased. Thirty-day mortality for AMICS patients was 60% (95% CI: 59-61) and substantially higher than the 8% (95% CI: 7.8-8.2) for AMI-only patients (mortality rate ratio: 11.4, 95% CI: 10.9-11.8). Over time, the mortality decreased after AMICS (2005: 68% to 2017: 57%, P for temporal change in adjusted analysis < .0001). We observed a slight decrease in AMICS hospitalization over time with changing practice patterns. Thirty-day mortality was markedly higher for patients with AMICS compared with AMI only, yet our results suggest improved 30-day survival over time after AMICS.
