Do patients with diabetes with new onset acute myocardial infarction present with different symptoms than non-diabetic patients?

The objective of this study was to investigate the differences in presenting symptoms between patients with and without diabetes being diagnosed with an acute myocardial infarction (AMI). A total of 5,900 patients with a first-time AMI were included into the analysis. All patients aged between 25 and 84 years were recorded by the population-based Myocardial Infarction Registry in Augsburg, Germany, between 2010 and 2017. The presence (yes/no) of 12 AMI typical symptoms during the acute event was assessed within the scope of a face-to-face interview. Multivariable adjusted logistic regression models were calculated to analyze the associations between presenting symptoms and diabetes mellitus in AMI patients. Patients with diabetes had significantly less frequent typical pain symptoms, including typical chest pain. Also, other symptoms like sweating, vomiting/nausea, dizziness/vertigo and fear of death/feeling of annihilation occurred significantly more likely in non-diabetic patients. The only exception was the symptom of shortness of breath, which was found significantly more often in patients with diabetes. In multivariable-adjusted regression models, however, the observed effects were attenuated. In patients younger than 55 years, the associations between diabetes and various symptoms were mainly missing. Type 2 diabetes mellitus is a risk factor not only for the development of AMI, but is also associated with an adverse outcome after AMI. Atypical clinical presentation additionally complicates the diagnostic process. It is therefore essential for physicians to be aware of the more often atypical symptoms that diabetic AMI patients report.

Association Between Acute Myocardial Infarction Symptoms and Short- and Long-term Mortality After the Event

BackgroundIn this study, we investigated various acute myocardial infarction (AMI) symptoms and their associations with short-term (28 day) and long-term mortality. MethodsThe analysis was based on 5900 patients, aged 25 to 84 years, with first-time AMI recorded by the population-based Myocardial Infarction Registry Augsburg between 2010 and 2017. Median follow-up time was 3.8 years (interquartile range: 1.1-6.3). As part of a face-to-face interview, the presence (yes/no) of 11 most common AMI symptoms at the acute event was assessed. Using multivariable-adjusted logistic regression and Cox regression models, the association between various symptoms and all-cause mortality was investigated. P values of the regression models were false discovery rate adjusted. ResultsPain in various body parts (chest pain, left and right shoulder/arm/hand, between shoulder blades), sweating, nausea/vomiting, dizziness and fear of death/feeling of annihilation were significantly associated with a decreased 28-day mortality after AMI. The pain symptoms and sweating were also significantly associated with a decreased long-term mortality. Shortness of breath was significantly associated with a higher long-term mortality. ConclusionsThe absence of several symptoms, including typical chest discomfort (chest pain or retrosternal pressure/tightness), is associated with unfavourable outcomes after AMI. This finding has implications for patient management and public health measures designed to encourage appropriate and prompt medical consultation of patients with atypical AMI symptoms.

Role of serum CAP1 protein in the diagnosis of patients with first-time acute myocardial infarction.

The dysregulation of adenylate cyclase-associated protein 1 (CAP1) is associated with a variety of inflammatory conditions. Here, we aimed to assess the role of serum CAP1 protein in predicting acute myocardial infarction (AMI), and to explore its effect and mechanism in vascular endothelial cells injury. ELISA was utilized to detected CAP1 protein expression in serum from 70 patients with first-time AMI at 0, 6, 12, 24, 48 hours and 7 days of the onset of chest pain. Receiver operating characteristic (ROC) curve analysis was administered to analyze the diagnostic power of CAP1 for AMI. The CCK-8 and 5-BrdU assays were applied to measure cell proliferation and inflammation in a model of oxidized low-density lipoprotein (ox-LDL) induced human umbilical vein endothelial cells (HUVEC). Luciferase reporter gene assay and Western blotting were used to assess the activity of NF-κB pathway. Results showed that serum CAP1 protein expression was upregulated in patients with first-time AMI, its expression was highest at 12 hours of the onset of chest pain. CAP1 protein was positively associated with the levels of cTnI and ox-LDL. CAP1 showed a relatively high diagnostic accuracy in patients with first-time AMI compared with cTnI, and CAP1 combined with cTnI had superior diagnostic value than CAP1 and cTnI alone. The expression of CAP1 protein was increased in supernatants of ox-LDL induced HUVEC in a dose- and time-dependent manner. CAP1 inhibited cell proliferation but promoted inflammation, and induced the activation of NF-κB pathway in vitro. To sum up, increased serum CAP1 expression might serve as a novel diagnostic biomarker for patients with first-time AMI, the mechanism might be related to its induction of NF-κB pathway activation causing abnormal proliferation and inflammation and thus mediating vascular endothelial cell injury.

Contrast-enhanced cardiac MRI is superior to non-contrast mapping to predict left ventricular remodeling at 6 months after acute myocardial infarction

ObjectivesParametric mapping constitutes a novel cardiac magnetic resonance (CMR) technique enabling quantitative assessment of pathologic alterations of left ventricular (LV) myocardium. This study aimed to investigate the clinical utility of mapping techniques with and without contrast agent compared to standard CMR to predict adverse LV remodeling following acute myocardial infarction (AMI).Materials and methodsA post hoc analysis was performed on sixty-four consecutively enrolled patients (57 ± 12 years, 54 men) with first-time reperfused AMI. Baseline CMR was obtained at 8 ± 5 days post-AMI, and follow-up CMR at 6 ± 1.4 months. T1/T2 mapping, T2-weighted, and late gadolinium enhancement (LGE) acquisitions were performed at baseline and cine imaging was used to determine adverse LV remodeling, defined as end-diastolic volume increase by 20% at 6 months.ResultsA total of 11 (17%) patients developed adverse LV remodeling. At baseline, patients with LV remodeling showed larger edema (30 ± 11 vs. 22 ± 10%LV; p < 0.05), infarct size (24 ± 11 vs. 14 ± 8%LV; p < 0.001), extracellular volume (ECVinfarct; 63 ± 12 vs. 47 ± 11%; p < 0.001), and native T2infarct (95 ± 16 vs. 78 ± 17 ms; p < 0.01). ECVinfarct and infarct size by LGE were the best predictors of LV remodeling with areas under the curve (AUCs) of 0.843 and 0.789, respectively (all p < 0.01). Native T1infarct had the lowest AUC of 0.549 (p = 0.668) and was inferior to edema size by T2-weighted imaging (AUC = 0.720; p < 0.05) and native T2infarct (AUC = 0.766; p < 0.01).ConclusionIn this study, ECVinfarct and infarct size by LGE were the best predictors for the development of LV remodeling within 6 months after AMI, with a better discriminative performance than non-contrast mapping CMR.Clinical relevance statementThis study demonstrates the predictive value of contrast-enhanced and non-contrast as well as conventional and novel CMR techniques for the development of LV remodeling following AMI, which might help define precise CMR endpoints in experimental and clinical myocardial infarction trials.Key Points• Multiparametric CMR provides insights into left ventricular remodeling at 6 months following an acute myocardial infarction.• Extracellular volume fraction and infarct size are the best predictors for adverse left ventricular remodeling.• Contrast-enhanced T1 mapping has a better predictive performance than non-contrast standard CMR and T1/T2 mapping.

The impact of end-stage kidney disease on mortality in patients after acute myocardial infarction: A nationwide study.

This study aimed to evaluate the impact of end-stage kidney disease (ESKD) on mortality in patients with first-time acute myocardial infarction (AMI). This was a retrospective nationwide cohort study. Patients diagnosed with first-time AMI between January 1, 2000, and December 31, 2012, were included. All patients were followed-up until death or December 31, 2012, whichever occurred first. A one-to-one propensity score matching technique was used to match patients with ESKD to those without ESKD of similar sex, age, comorbidities, and coronary intervention (including percutaneous coronary intervention [PCI] and coronary artery bypass grafting [CABG]). Kaplan-Meier cumulative survival curves were constructed to compare AMI patients with and without ESKD. A total of 186 112 patients were enrolled and 8056 patients with ESKD were identified. Propensity score matched 8056 patients without ESKD were included in the comparison. Overall, the 12-year mortality rate was significantly higher in patients with ESKD than in those without ESKD (log-rank p < 0.0001), including the sex, age, and PCI and CABG subgroups. In Cox proportional-hazard regression analysis, ESKD was an independent risk factor for mortality after patients suffered from first-time AMI (hazard ratio, 1.77; 95% CI, 1.70-1.84; p < 0.0001). A forest plot for subgroup analysis revealed that in AMI patients, ESKD had a higher impact on mortality in male; younger age; without comorbidities such as hypertension, diabetes mellitus, peripheral vascular disease, heart failure, cerebrovascular accident, and chronic obstructive pulmonary disease; and receiving PCI and CABG subgroups. ESKD significantly increases the mortality risk in patients with first-time AMI, including both sexes, different ages, and whether PCI or CABG was performed. In patients with AMI, ESKD has a high impact on mortality in male, younger age, without comorbidities, and those undergoing PCI and CABG.

Risk of Acute Myocardial Infarction Following Invasive Pneumococcal Disease: How Much Is Due to Antibiotic Treatments?

To the Editor—We studied with interest the article by Wiese et al [1] that found a significant association between hospitalization due to acute myocardial infarction (AMI) and laboratory-confirmed invasive pneumococcal disease (IPD). The authors included 324 patients hospitalized for a first-time AMI between 2003 and 2019. Follow-ups were started 1 year before the AMI date and continued to the date of death, 1 year after the AMI date, or end of the study (December 2019). The date of IPD detection was considered as “date 0,” and the follow-up period was divided into 4 shorter risk periods: pre-IPD (days −7 to −1), current IPD (days 0–7), post-IPD (days 8–28), and a control period (all other follow-up time). Compared to the control period, the incidence of AMI was significantly higher during pre-IPD (incidence rate ratio [IRR], 10 [95% confidence interval {CI}, 6.3–17]) and current IPD (IRR, 93 [95% CI, 72–120]) but nonsignificantly elevated in the post-IPD (IRR, 1.8 [95% CI, .86–3.9]) risk period [1]. Interestingly, the frequency of hospitalizations due to AMI peaked on the day before or the same day the microbiologic specimens were collected. Furthermore, >85% of the IPD cases were identified around the AMI hospitalization day. The strong association between AMI and IPD is important, especially because some IPDs are potentially vaccine preventable.

Long-Term Follow-Up After Acute Myocardial Infarction According to Beta-Blocker Dose

ObjectiveOur purpose was to examine the association between beta-blocker dose and mortality following acute myocardial infarction. MethodsThis nationwide cohort study enrolled all patients admitted for first-time acute myocardial infarction in Denmark between July 1, 2004 and December 31, 2014, using the Danish National Patient Registry. Patients alive 15 days after admission were followed until death, emigration, or December 31, 2014. Patients were categorized according to daily beta-blocker consumption (0%, >0%-12.5%, >12.5%-25%, >25%-50%, >50%-100%, or >100% of the currently recommended target dose) based on prescriptions registered in the Danish National Database of Reimbursed Prescriptions. Doses were continuously updated during follow-up. Mortality rate ratios (MRRs) were computed and adjusted for confounders using Cox proportional hazard regression. ResultsAmong 65,125 patients followed, any beta-blocker dose was associated with significant mortality reduction compared with no treatment (adjusted MRR ≤ 0.92 [95% confidence interval {CI}: 0.86-0.98]). The largest reduction was observed within the first year for beta-blocker doses >25%-50% (adjusted MRR = 0.55 [95% CI: 0.50-0.60]). After 1 year, doses >50%-100% were associated with the largest mortality reduction (adjusted MRR = 0.58 [95% CI: 0.50-0.67]), but it did not differ significantly from that associated with doses >25%-50% (adjusted MRR = 0.68 [95% CI: 0.61-0.77]). ConclusionsAny beta-blocker dose was associated with significant mortality reduction following acute myocardial infarction compared with no treatment. Doses >25%-50% of the currently recommended target dose were associated with maximal mortality reduction within the first year after acute myocardial infarction, suggesting that higher doses are unnecessary.

Short and long-term prognosis of admission hyperglycemia in patients with and without diabetes after acute myocardial infarction: a retrospective cohort study

ObjectiveAdmission hyperglycemia is associated with poor prognosis in patients with acute myocardial infarction (AMI), but the effects of baseline diabetes status on this association remain elusive. We aim to investigate the impact of admission hyperglycemia on short and long-term outcomes in diabetic and non-diabetic AMI patients.MethodsIn this retrospective cohort study, 3330 patients with regard to first-time AMI between July 2012 and July 2020 were identified. Participants were divided into two groups according to diabetes status (1060 diabetic patients and 2270 non-diabetic patients). Thereafter, they were divided into four groups according to diabetes status-specific cutoff values of fasting blood glucose (FBG) identified by restricted cubic spline. Short-term outcomes included in-hospital death and cardiac complications. Long-term outcomes were all-cause mortality and major adverse cardiovascular events (MACE). Inverse probability of treatment weighting (IPTW) was conducted to adjust for baseline differences among the groups, followed by a weighted Cox proportional hazards regression analysis to calculate hazard ratios and 95% confidence intervals for all-cause mortality associated with each FBG category. Subgroup analysis and sensitivity analysis were performed to test the robustness of our findings.ResultsDuring a median follow-up of 3.2 years, 837 patients died. There was a significant interaction between diabetes status and FBG levels for all-cause mortality during long-term follow-up (p-interaction < 0.001). Moreover, restricted cubic spline curves for the association between FBG and all-cause mortality followed a J shape in patients with diabetes and a non-linear in patients without diabetes. Kaplan–Meier analysis demonstrated greater survival in non-hyperglycemia patients compared to hyperglycemia patients for both diabetic and non-diabetic patients groups. Survival of hyperglycemia patients without diabetes greater than in hyperglycemia patients with diabetes. In the weighted Multivariable cox analysis, admission hyperglycemia predicted higher short and long-term mortality. Subgroup analysis and sensitivity analysis showed the robustness of the results.ConclusionsThe inflection points of FBG level for poor prognosis were 5.60 mmol/L for patients without diabetes and 10.60 mmol/L for patients with diabetes. Admission hyperglycemia was identified as an independent predictor of worse short and long-term outcomes in AMI patients, with or without diabetes. These findings should be explored further.

Association between admission ECG changes and long-term mortality in patients with an incidental myocardial infarction: Results from the KORA myocardial infarction registry

BackgroundThe aim of this study was to examine the predictive value of specific changes in admission ECG on long-term outcome in acute myocardial infarction (AMI). MethodsFrom 2000 until 2017 all AMI cases (n = 9,689) in the study area of Augsburg, Germany, were prospectively recorded. For this study, all patients with a first-time AMI, who survived the first 28 days, were considered. Median observational time was 6.7 years (IQR: 3.6–10.9). Each case was assigned to one of the following groups according to the admission ECG: ‘ST-segment elevation’, ‘ST-segment depression’, ‘T-wave inversion’, ‘unspecific changes’, ‘normal ECG’ and ‘bundle branch block’ (BBB). Multivariable adjusted COX regression models were calculated to compare long-term all-cause mortality. ResultsThe final regression model revealed a significantly higher mortality among patients with BBB (HR: 1.52 [1.34–1.73], p-value: < 0.001) and ‘ST-segment depression’ (HR: 1.16 [1.03–1.29], p-value: 0.01252) compared to the STEMI group (reference group). The ‘normal ECG’ group (HR: 0.76 [0.66–0.87], p-value: < 0.001) on the other hand was associated with significantly lower long-term mortality. The ‘T-wave inversion’ group (HR: 1.08 [0.96–1.21]) and the ‘unspecific changes’ group (HR: 1.05 [0.94–1.17]) did not differ significantly from the STEMI group. ConclusionST-segment depressions and BBB admission ECGs go along with higher long-term mortality in AMI patients compared to STEMI cases. This should be taken into account by physicians when treating patients with NSTEMIs. Only the complete absence of AMI-related ECG changes predicts a more favorable outcome.

Health-related Quality of Life Increases After First-time Acute Myocardial Infarction: a Population-based Study.

IntroductionAcute myocardial infarction (AMI) affects patients’ health-related quality of life (HRQOL). AMI may decrease HRQOL, thus negatively affecting QOL. However, the improvements in interventional treatment and early rehabilitation after AMI may have a positive effect on HRQOL.AimWe evaluated HRQOL in patients after the first AMI treated in a reference cardiology centre in Poland and assessed which clinical variables affect HRQOL after AMI.Material and methodsWe prospectively evaluated HRQOL in 60 consecutive patients suffering after their first AMI during the index hospitalisation and again after 6 months, using: (i) MacNew, (ii) World Health Organization Quality of Life (WHOQOL) BREF, and (iii) Short Form (SF) 36.ResultsAs measured by the MacNew questionnaire, global, social, and physical functioning did not change (p≥0.063), whereas emotional functioning improved 6 months after AMI, compared to index hospitalisation (p=0.002). As measured by WHOQOL BREF, physical health, psychological health, and environmental functioning did not change (p≥0.321), whereas social relationships improved 6 months after AMI (p=0.042). As assessed by SF-36, the global HRQOL improved after AMI (p=0.044). Patients with improved HRQOL in SF-36 often had a higher baseline body mass index (p=0.046), dyslipidaemia (p=0.046), and lower left ventricle ejection fraction (LVEF; p=0.013). LVEF<50% was the only variable associated with improved HRQOL in multivariate analysis (OR 4.463, 95% CI 1.045 - 19.059, p=0.043).ConclusionsHRQOL increased 6 months after the first AMI, especially in terms of emotional functioning and social relationships. Patients with LVEF<50% were likely to have improved HRQOL.

Central Sleep Apnea Is Associated with an Abnormal P-Wave Terminal Force in Lead V1 in Patients with Acute Myocardial Infarction Independent from Ventricular Function.

Sleep-disordered breathing (SDB) is highly prevalent in patients with cardiovascular disease. We have recently shown that an elevation of the electrocardiographic (ECG) parameter P wave terminal force in lead V1 (PTFV1) is linked to atrial proarrhythmic activity by stimulation of reactive oxygen species (ROS)-dependent pathways. Since SDB leads to increased ROS generation, we aimed to investigate the relationship between SDB-related hypoxia and PTFV1 in patients with first-time acute myocardial infarction (AMI). We examined 56 patients with first-time AMI. PTFV1 was analyzed in 12-lead ECGs and defined as abnormal when ≥4000 µV*ms. Polysomnography (PSG) to assess SDB was performed within 3–5 days after AMI. SDB was defined by an apnea-hypopnea-index (AHI) >15/h. The multivariable regression analysis showed a significant association between SDB-related hypoxia and the magnitude of PTFV1 independent from other relevant clinical co-factors. Interestingly, this association was mainly driven by central but not obstructive apnea events. Additionally, abnormal PTFV1 was associated with SDB severity (as measured by AHI, B 21.495; CI [10.872 to 32.118]; p < 0.001), suggesting that ECG may help identify patients suitable for SDB screening. Hypoxia as a consequence of central sleep apnea may result in atrial electrical remodeling measured by abnormal PTFV1 in patients with first-time AMI independent of ventricular function. The PTFV1 may be used as a clinical marker for increased SDB risk in cardiovascular patients.

Evaluation of different late left ventricular remodeling definitions for predicting long-term outcomes in acute myocardial infarction patients undergoing percutaneous coronary intervention

Abstract Background Late left ventricular remodeling (LLVR) after the index acute myocardial infarction (AMI) is a common complication, and is associated with poor outcome. However, the optimal definition of LLVR has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding the influence of different LLVR definitions on long-term outcomes in AMI patients undergoing percutaneous coronary intervention (PCI). Purpose To explore the impact of different definitions of LLVR on long-term mortality, re-hospitalization or an urgent visit for heart failure, and identify which definition was more suitable for predicting long-term outcomes in AMI patients undergoing PCI. Methods We prospectively observed 460 consenting first-time AMI patients undergoing PCI from January 2012 to December 2018. LLVR was defined as a ≥20% increase in left ventricular end-diastolic volume (LVEDV), or a &amp;gt;15% increase in left ventricular end-systolic volume (LVESV) from the initial presentation to the 3–12 months follow-up, or left ventricular ejection fraction (LVEF) &amp;lt;50% at follow up. These parameters of the cardiac structure and function were measuring through the thoracic echocardiography. The association of LLVR with long-term prognosis was investigated by Cox regression analysis. Results The incidence rate of LLVR was 38.1% (n=171). The occurrence of LLVR according to LVESV, LVEDV and LVEF definition were 26.6% (n=117), 31.9% (n=142) and 11.5% (n=51), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable Cox regression analysis revealed LLVR of LVESV definition [hazard ratio (HR): 2.50, 95% confidence interval (CI): 1.19–5.22, P=0.015], LLVR of LVEF definition (HR: 16.46, 95% CI: 6.96–38.92, P&amp;lt;0.001) and LLVR of Mix definition (HR: 5.86, 95% CI: 2.45–14.04, P&amp;lt;0.001) were risk factors for long-term mortality, re-hospitalization or an urgent visit for heart failure. But only LLVR of LVEF definition was a risk predictor for long-term mortality (HR: 6.84, 95% CI: 1.98–23.65, P=0.002). Conclusions LLVR defined by LVESV or LVEF may be more suitable for predicting long-term mortality, re-hospitalization or an urgent visit for heart failure in AMI patients undergoing PCI. However, only LLVR defined by LVEF could be used for predicting long-term mortality. Funding Acknowledgement Type of funding sources: None.

Establishment of a prognostic model based on the Sequential Organ Failure Assessment score for patients with first-time acute myocardial infarction.

ObjectiveThis study aimed to identify the prognostic factors of patients with first-time acute myocardial infarction (AMI) and to establish a nomogram for prognostic modeling.MethodsWe studied 985 patients with first-time AMI using data from the Multi-parameter Intelligent Monitoring for Intensive Care database and extracted their demographic data. Cox proportional hazards regression was used to examine outcome-related variables. We also tested a new predictive model that includes the Sequential Organ Failure Assessment (SOFA) score and compared it with the SOFA-only model.ResultsAn older age, higher SOFA score, and higher Acute Physiology III score were risk factors for the prognosis of AMI. The risk of further cardiovascular events was 1.54-fold higher in women than in men. Patients in the cardiac surgery intensive care unit had a better prognosis than those in the coronary heart disease intensive care unit. Pressurized drug use was a protective factor and the risk of further cardiovascular events was 1.36-fold higher in nonusers.ConclusionThe prognosis of AMI is affected by age, the SOFA score, the Acute Physiology III score, sex, admission location, type of care unit, and vasopressin use. Our new predictive model for AMI has better performance than the SOFA model alone.

2.5-fold increased risk of recurrent acute myocardial infarction with familial hypercholesterolemia

Background and aimsA first-time acute myocardial infarction (AMI) is a severe diagnosis that leads to initiation or intensification of lipid-lowering medication to prevent recurrent events. Individuals with familial hypercholesterolemia (FH) already use high-intensity lipid-lowering medication at the time of an incident AMI due to their diagnosis. Hence, we hypothesized that compared with matched non-FH controls, individuals with genetically verified FH have increased mortality and risk of recurrent AMI after their first event. MethodsThe study population comprised 4871 persons with genetically verified FH, and 96,251 age and sex matched controls randomly selected from the Norwegian population. Data were obtained from the Cardiovascular Disease in Norway Project, the Norwegian Patient Registry and the Norwegian Cause of Death Registry. Incidence of AMI, all-cause mortality and recurrent AMI after incident AMI were analyzed for the period 2001–2017. Incidence and mortality were compared using hazard ratios (HR) from Cox regression. Risk of recurrent AMI was compared using sub-hazard ratios (SHR) from competing risk regression with death as a competing event. ResultsWe identified 232 individuals with FH and 2118 controls with an incident AMI [HR 2.10 (95% CI 1.83–2.41)]. Among survivors ≥29 days after the incident AMI, both mortality [HR = 1.45 (95% CI: 1.07–1.95)] and recurrent AMI [SHR = 2.53 (95% CI: 1.88–3.41)] were significantly increased among individuals with FH compared with non-FH controls. ConclusionsIndividuals with FH have increased mortality and increased risk of recurrent AMI after the first AMI event compared with controls. These findings call for intensive follow-up of individuals with FH following an AMI.

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.

Diabetes Mellitus Does Not Negatively Impact Hospitalizations for Systemic Sclerosis

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.

Cellulitis Caused by Diabetic Wound in Diabetes Mellitus Type 2 with Unstable Glucose Level and Systemic Complications

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.
