Abstract Purpose Thyroid dysfunction in patients with cardiac disease is associated with worse outcomes. This study aimed to evaluate the prevalence and analyse predictors and outcomes of thyroid dysfunction in patients presenting with an acute myocardial infarction (AMI). Methods A prospective multicentre observational study of patients recruited from six acute hospitals within the North of England. Consecutive patients without previous thyroid disease presenting with both ST-elevation AMI (STEMI) and non-ST-elevation AMI (NSTEMI) were recruited to the Thyroxine in Acute Myocardial Infarction 1 (ThyrAMI-1) cohort study between December 2014 and 2016. Thyroid profile, standard biochemistry measurements and demographic information were obtained within 12 h of admission to hospital. Multivariable logistic regression analyses were performed to assess the predictors of thyroid dysfunction and Cox proportional hazards analyses were utilised to compare all-cause mortality by categories of thyroid dysfunction up to June 2019. Results Of the 1802 participants analysed, 1440 (79.9%) were euthyroid, 312 (17.3%) had subclinical hypothyroidism (SCH), 22 (1.2%) had subclinical hyperthyroidism (SHyper) and 25 (1.3%) had low T3 syndrome (LT3S). Predictors for SCH were increasing age, female sex, higher thyroid peroxidase antibody (TPOAb) levels, higher serum creatinine levels and early morning sampling time (between 00:01–06:00 h). The predictors of SHyper were lower body mass index and afternoon sampling time (between 12:01 and 18:00 h). Predictors of LT3S were increasing age, higher creatinine levels and presence of previous ischaemic heart disease. Compared to the euthyroid group, patients with LT3S had higher all-cause mortality; adjusted hazard ratio (95% CI) of 2.02 (1.03–3.95), p = 0.04, whereas those with SCH and SHyper did not exhibit significantly increased mortality; adjusted hazard ratios (95% CI) of 1.05 (0.74–1.49), p = 0.79 and 0.27 (0.04–1.95), p = 0.19, respectively. Conclusions Thyroid dysfunction is common in AMI patients on admission to hospital and our data provide an understanding regarding which factors might influence thyroid dysfunction in these patients. Furthermore, the negative association between LT3S and increased mortality post-AMI has once again been highlighted by this study. More research is required to assess if treatment of thyroid dysfunction improves clinical outcomes.

Background: High sensitivity CRP (hs-CRP) has attracted intense interest in risk assessment. We aimed to explore its prognostic value in patients with acute myocardial infarction (AMI).Methods and Results: We enrolled 4,504 consecutive AMI patients in this prospective cohort study. The associations between hs-CRP levels with the incidence of in-hospital HF was evaluated by logistic regression analysis. The association between hs-CRP levels and the cumulative incidence of HF after hospitalization were evaluated by Fine-Gray proportional sub-distribution hazards models, accounting for death without HF as competing risk. Cox proportional hazards regression models were constructed to estimate the association between hs-CRP levels and the risk of all-cause mortality. Over a median follow-up of 1 year, 1,112 (24.7%) patients developed in-hospital HF, 571 (18.9%) patients developed HF post-discharge and 262 (8.2%) patients died. In the fully adjusted model, the risk of in-hospital heart failure (HF) [95% confidence intervals (CI)] among those patients with hs-CRP values in quartile 3 (Q3) and Q4 were 1.36 (1.05–1.77) and 1.41 (1.07–1.85) times as high as the risk among patients in Q1 (p trend < 0.001). Patients with hs-CRP values in Q3 and Q4 had 1.33 (1.00–1.76) and 1.80 times (1.37–2.36) as high as the risk of HF post-discharge compared with patients in Q1 respectively (p trend < 0.001). Patients with hs-CRP values in Q3 and Q4 had 1.74 (1.08–2.82) and 2.42 times (1.52–3.87) as high as the risk of death compared with patients in Q1 respectively (p trend < 0.001).Conclusions: Hs-CRP was found to be associated with the incidence of in-hospital HF, HF post-discharge and all-cause mortality in patients with AMI.

Abstract Objective The objective of this study was to determine the impact of blood sample timing on the diagnosis of subclinical thyroid dysfunction (SCTD) and mortality in patients with acute myocardial infarction (AMI). Patients, Design, and Main Outcome Measures Patients with AMI had thyroid function evaluated on admission between December 2014 and December 2016 and those with abnormal serum thyrotropin (TSH) had repeat thyroid function assessed at least a week later. The association between sample timing and SCTD was evaluated by logistic regression analysis. Secondary outcomes were confirmation of SCTD on repeat testing and all-cause mortality up to June 2018. Results Of the 1806 patients [29.2% women, mean (± standard deviation) age of 64.2 (±12.1) years] analyzed, the prevalence of subclinical hypothyroidism (SCH) was 17.2% (n = 311) and subclinical hyperthyroidism (SHyper) was 1.2% (n = 22) using a uniform TSH reference interval. The risk of being diagnosed with SCTD varied by sample timing in fully-adjusted models. The risk of SCH was highest between 00.01 and 06.00 hours and lowest between 12.01 and 18.00 hours, P for trend <.001, and risk of SHyper was highest between 12.01 hours and 18.00 hours and lowest between 00.01 hours and 06.00 hours. Furthermore, time of the initial sample was associated with the risk of remaining in a SCH state subsequently. Mortality in SCH patients was not elevated when a uniform TSH reference interval was utilized. However, when time period–specific TSH reference ranges were utilized, the mortality risk was significantly higher in SCH patients with HR (95% CI) of 2.26 (1.01–5.19), P = .04. Conclusions Sample timing impacts on the diagnosis and prognosis of SCH in AMI patients. If sample timing is not accounted for, SCH is systemically misclassified, and its measurable influence on mortality is lost.

Introduction: Hospitalization for acute myocardial infarction (AMI) affects medication adherence in prevalent statin users. Our objective was to estimate the association between changes in statin adherence and all-cause mortality after AMI discharge. Hypothesis: Patients who are adherent both pre- and post-AMI have the lowest risk of all-cause mortality. Methods: Medicare administrative claims were used to identify AMI hospitalizations in 2008-2010. Patients were ≥66 years old, continuously enrolled ≥360 days pre-AMI with a statin prescription claim, discharged to home/self-care, and survived ≥180 days post-AMI with continuous enrollment. Statin adherence was measured in the 180 days pre- and post-AMI hospitalization using proportion of days covered and categorized as severely nonadherent, moderately nonadherent, and adherent. The exposure was categorical change in statin adherence from pre- to post-AMI (9 categories, see Figure); adherent/adherent was the reference group. Patients were followed for all-cause mortality from 180 days post-discharge for up to 18 months. A multivariable Cox proportional hazards model estimated hazard ratios (HRs). Results: Of 101,011 eligible patients, 15% decreased, 20% increased, and 64% did not change statin adherence categories. Compared to patients who were adherent pre- and post-AMI, the adjusted HR (95% confidence intervals [CIs]) for patients who increased from severely nonadherent to adherent was 0.93 (95% CI: 0.85-1.02); other increases in adherence had similar HRs (see Figure). Compared to patients who were adherent pre- and post-AMI, the adjusted HR for patients who decreased from adherent to severely nonadherent was 1.22 (95% CI: 1.13-1.33); other decreases in adherence had similar HRs. Conclusions: Although patients with decreased statin adherence had the worst mortality outcomes, those with increased adherence had similar or better outcomes than continuously adherent patients, showing that, even after an AMI, it is not too late to improve statin adherence.

ObjectiveWe investigated the benefit of Impella, a modern percutaneous mechanical support (pMCS) device, versus former standard intra-aortic balloon pump (IABP) in acute myocardial infarction complicated by cardiogenic shock (AMICS).MethodsThis single-centre, retrospective study included patients with AMICS receiving pMCS with either Impella or IABP. Disease severity at baseline was assessed with the IABP-SHOCK II score. The primary outcome was all-cause mortality at 30 days. Secondary outcomes were parameters of shock severity at the early postimplantation phase. Adjusted Cox proportional hazards models identified independent predictors of the primary outcome.ResultsOf 116 included patients, 62 (53%) received Impella and 54 (47%) IABP. Despite similar baseline mortality risk (IABP-SHOCK II high-risk score of 18 % vs 20 %; p = 0.76), Impella significantly reduced the inotropic score (p < 0.001), lactate levels (p < 0.001) and SAPS II (p =0.02) and improved left ventricular ejection fraction (p = 0.01). All-cause mortality at 30 days was similar with Impella and IABP (52 % and 67 %, respectively; p = 0.13), but bleeding complications were more frequent in the Impella group (3 vs 4 units of transfused erythrocytes concentrates due to bleeding complications, p = 0.03). Previous cardiopulmonary resuscitation (HR 3.22, 95% CI 1.76 to 5.89; p < 0.01) and an estimated intermediate (HR 2.77, 95% CI 1.42 to 5.40; p < 0.01) and high (HR 4.32 95% CI 2.03 to 9.24; p = 0.01) IABP-SHOCK II score were independent predictors of all-cause mortality.ConclusionsIn patients with AMICS, haemodynamic support with the Impella device had no significant effect on 30-day mortality as compared with IABP. In these patients, large randomised trials are warranted to ascertain the effect of Impella on the outcome.

Acute myocardial infarction (AMI) is a leading cause of death and not a few of these patients are combined with acidemia. This study aimed to detect the association of acidemia with short-term mortality of AMI patients. A total of 972 AMI patients were selected from the Medical Information Mart for Intensive Care (MIMIC) III database for analysis. Propensity-score matching (PSM) was used to reduce the imbalance. Kaplan-Meier survival analysis was used to compare the mortality, and Cox-proportional hazards model was used to detect related factors associated with mortality. After PSM, a total of 345 non-acidemia patients and 345 matched acidemia patients were included. The non-acidemia patients had a significantly lower 30-day mortality (20.0% vs. 28.7%) and lower 90-day mortality (24.9% vs. 31.9%) than the acidemia patients ( P < 0.001 for all). The severe-acidemia patients (PH < 7.25) had the highest 30-day mortality (52.6%) and 90-day mortality (53.9%) than non-acidemia patients and mild-acidemia (7.25 ≤ PH < 7.35) patients ( P < 0.001). In Cox-proportional hazards model, acidemia was associated with improved 30-day mortality (HR = 1.518; 95%CI = 1.110-2.076, P = 0.009) and 90-day mortality (HR = 1.378; 95%CI = 1.034 -1.837, P = 0.029). These results suggest that severe acidemia is associated with improved 30-day mortality and 90-day mortality of AMI patients.

Objective: To examine the association between exposure to psychological (anger, anxiety) and physical (high activity levels, coffee consumption) challenge immediately prior to myocardial infarction (MI) as risk indicator of mortality at 10-year follow-up. Methods: Participants of the Determinants of Myocardial Infarction Onset Study (N=2176, mean age 60.1±12.5 yrs, 29.2% women) were interviewed to assess exposure to several potential triggers immediately prior to MI, including anger, anxiety, physical activity and coffee. All-cause mortality was assessed using the National Death Index for 10 years follow-up. We constructed Cox proportional hazards models with 95% confidence intervals to examine the relationship between exposure to these potential triggers in the 2 hours prior to MI onset and the rate of all-cause mortality, adjusting for demographic and clinical characteristics. Results: Exposure to anger, anxiety, physical activity or coffee consumption prior to MI was associated with a 30% higher mortality rate over 10 years (HR=1.30, 95%CI=1.06-1.59, p =0.011) compared to patients who were not exposed to any of these potential triggers. This association was stronger for the first 3 years of follow-up (HR=1.59, 95%CI=1.16-2.19, p =0.004) and weaker for years 3 to 10 (HR=1.14, 95%CI=0.88-1.48, p =0.32). In separate analyses for each exposure, there was a higher mortality rate associated with anxiety (HR=1.44, 95%CI=1.09-1.91, p =0.010) and a suggestion of a higher rate for anger (HR=1.33, 95%CI=0.97-1.81, p =0.075), but no association for physical activity or coffee consumption. Sensitivity analyses showed stronger associations for women than men, and patients aged 65 and older compared to younger patients. Discussion: MI following episodes of anger, anxiety, physical activity or coffee consumption is associated with higher all-cause mortality in the following 10 years. This association was strongest for anxiety and slightly lower for anger but there was no evidence of a higher mortality rate among MI patients reporting physical activity or coffee consumption immediately prior to MI.

Background Low vitality, characterized by fatigue and lack of energy, is common among survivors of acute myocardial infarction (AMI) and has been shown to be associated with increased risk of primary and secondary cardiac events. The goal of this study was to determine whether an association between vitality and recurrent cardiac events (nonfatal MI, cardiac death) among acute MI survivors persists after controlling for possible physiological and psychological confounders. Design and methods Incident AMI survivors ( n = 1328) from Erie and Niagara (New York) county hospitals were enrolled and followed up to 9 years. Vitality was measured by the Short Form-36 on a 0–100 scale approximately 4 months post-AMI. Cox proportional hazards models were developed to assess the vitality-recurrent event association controlling for traditional cardiovascular disease risk factors, index MI severity, and psychological correlates of vitality. Results Low-vitality individuals at baseline were more likely females, of higher BMI, smoking, diabetic, less physically active, and to have worse depression scores. Vitality was not strongly associated with MI severity markers. Lower vitality scores were associated with increased risk of recurrent cardiac events: adjusted hazard ratios (95% CI) for vitality scores 51–79, 21–50, and ≤ 20 (compared with ≥ 80) were 1.2 (0.8, 1.8), 1.4 (0.9, 2.2), and 2.9 (1.5, 5.4), respectively ( Ptrend = 0.005). Conclusion Low vitality was associated with increased risk of recurrent cardiac events among AMI survivors after controlling for physiological and psychological confounders. Mechanistic links with vitality should be sought as interventional targets.

Abstract Aim In this study, we evaluated the utility of neutrophil percentage-to-albumin ratio (NPAR) in predicting in critically ill patients with acute myocardial infarction (AMI). Methods the information of patients were collected from Medical Information Mart for Intensive Care III (MIMIC III) database. Admission NPAR was calculated as neutrophil percentage divided by serum albumin. The endpoints of this study were 30-day, 90-day, 180-day, and 365-day all-cause mortality. Cox proportional hazards models and subgroup analyses were used to determine the relationship between admission NPAR and these endpoints. Results 798 critically ill patients with AMI were enrolled in. After adjustments for age, race and gender, higher admission NPAR was associated with increased risk of 30-day, 90-day, 180-day, and 365-day all-cause mortality in critically ill patients with AMI. And after adjusting for possible confounding variables, two different trends have emerged. Stratified by tertiles, high admission NPAR was independently associated with 180-day and 365-day all-cause mortality in critically ill patients with AMI (tertile 3 vs. tertile 1: adjusted HR, 95%CI: 1.71,1.10-2.66, p<0.05;1.66,1.10-2.51, p<0.05). In other hand, stratified by quartiles, highest admission NPAR levels were independently associated with 90-day, 180-day and 365-day all-cause mortality (quartile 4 vs. quartile 1: adjusted HR, 95% CI: 2.36,1.32-4.23, p<0.05; 2.58,1.49-4.47, p<0.05; 2.61,1.56-4.37, p<0.05). ROC test showed that admission NPAR had a moderate ability to predict all-cause mortality of critically ill patients with AMI. No obvious interaction was found by subgroup analysis in most subgroups. Conclusions admission NPAR was an independent predictor for 180-day and 365-day all-cause mortality in critically ill patients with AMI.

Multiple biomarkers have been studied to assess risk for future coronary events. Fibrinogen is involved in platelet aggregation, thrombus formation, and is a marker of inflammation. Furthermore, prothrombin time-derived fibrinogen levels are widely available with routine coagulation assays. We retrospectively evaluated admission derived fibrinogen, BNP and CRP levels as well as baseline clinical and procedural characteristics of 475 consecutive patients admitted with acute myocardial infarction who subsequently underwent stent placement. Major adverse cardiac event (MACE) outcomes data were collected to two years after index admission. Higher quartiles of admission fibrinogen levels were associated with increased hazard of death from any cause (log-rank p-value <0.001), non-fatal myocardial infarction (log-rank p-value <0.001), and any MACE (log-rank p-value = 0.004) at two years. In a Cox proportional hazards multivariate model including the covariates age (10 years), heart failure class, smoking status, diabetes, hypertension, cerebrovascular disease, history of renal failure, previous PCI and/or CABG, multivessel coronary disease, BNP and CRP, increased admission derived fibrinogen remained a significant predictor of increased hazard of MACE at two years [HR 2.22 (1.03– 4.77)]. In the same model, BNP [HR 0.95 (0.82–1.08)] and CRP [HR 1.22 (1.01–1.47)] were less robust prognosticators. In patients admitted with an acute myocardial infarction who undergo PCI with stent placement, admission derived fibrinogen levels, a widely available analyte, are more strongly predictive of future major adverse cardiac events than BNP and CRP.

Aims: Recent studies have found circulating concentrations of the gastrointestinal hormone GLP-1 to be an excellent predictor of cardiovascular risk in patients with myocardial infarction. This illustrates a yet not appreciated crosstalk between the gastrointestinal and cardiovascular systems, which requires further investigation. The gut-derived hormone Peptide YY (PYY) is secreted from the same intestinal L-cells as GLP-1. Relevance of PYY in the context of cardiovascular disease has not been explored. In this study, we aimed to investigate PYY serum concentrations in patients with acute myocardial infarction and to evaluate their association with cardiovascular events. Material and Methods: PYY levels were assessed in 834 patients presenting with acute myocardial infarction (553 Non-ST-Elevation Myocardial Infarction (NSTEMI) and 281 ST-Elevation Myocardial Infarction (STEMI)) at the time of hospital admission. The composite outcomes of first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke (3-P-MACE), and all-cause mortality were assessed with a median follow-up of 338 days. Results: PYY levels were significantly associated with age and cardiovascular risk factors, including hypertension, diabetes, and kidney function in addition to biomarkers of heart failure (NT-pro BNP) and inflammation (hs-CRP). Further, PYY was significantly associated with 3-P-MACE (HR: 1.7; 95% CI: 1–2.97; p = 0.0495) and all-cause mortality (HR: 2.69; 95% CI: 1.61–4.47; p = 0.0001) by univariable Cox regression analyses, which was however lost after adjusting for multiple confounders. Conclusions: PYY levels are associated with parameters of cardiovascular risk as well as cardiovascular events and mortality in patients presenting with acute myocardial infarction. However, this significant association is lost after adjustment for further confounders.
