Abstract Background Chronic kidney disease (CKD) are associated with acute myocardial infarction (AMI). High-sensitive cardiac troponin (hs-cTn) has been evidenced to enhance the early diagnostic accuracy of AMI, but hs-cTn levels are often chronically elevated in CKD patients, which reduces their diagnostic utility. The aim of this study was to derive optimal cutoff-values of hs-cTn levels in patients with CKD and suspected AMI. Methods In this retrospective paper, a total of 3295 patients with chest pain (2758 in AMI group and 537 in Non-AMI group) were recruited, of whom 23.1% were had an estimated glomerular filtration rate (eGFR) of < 60 mL min−1 (1.73 m2)−1. Hs-cTnI values were measured at presentation. Results AMI was diagnosed in 83.7% of all patients. The optimal value of hs-TnI in diagnosing AMI was 1.15 ng mL−1, which were higher in males than females comparing different cutoff-values of subgroups divided by age, gender and renal function, and which increased monotonically with decreasing of eGFR because in patients with CKD without AMI, the correlation between hs-cTnI and renal function is low but significant (r2 = 0.067, P < 0.001). Conclusions Different optimal cutoff-values of hs-cTnI in the diagnosis of AMI in patients with CKD were helpful to the clinical diagnosis of AMI in various populations and were higher in males than females, but which was needed to be validated by multicenter randomized controlled clinical studies in the future.

Aim: To explore, which differential diagnoses to consider in individuals with elevated troponins without acute myocardial infarction (AMI), and the mortality for those individuals. Methods: Retrospective, register-based study on a representative sample of the Danish population with the following inclusion criteria: High-sensitive troponin I (hs-TnI) ≥25 ng/L, age ≥18 years, and exclusion of AMI. Results: 3067 individuals without AMI but increased hs-TnI were included. Most frequent discharge diagnoses: Pneumonia (12.8%), Aortic valve disorder (11.3%), Medical observation (10.9%) and Heart failure (8.9%). The 30-days and one-year mortality was 15.8% and 32.0%, respectively. Conclusions: A selected number of alternative diagnoses must be considered in individuals with increased hs-TnI. Due to high mortality it is crucial to carefully evaluate these individuals despite the absence of AMI.

Significant Difference

Several studies have shown that both chronic kidney disease (CKD) and diabetes mellitus are risk factors for mortality in patients with acute myocardial infarction (AMI). This study was undertaken to investigate influence of CKD on the prognostic significance of diabetes in patients with AMI. Between January 1996 and December 2005, 888 patients with AMI underwent coronary angiography within 24 hours after the onset of chest pain. CKD was difined estimated glomerular filtration rate (eGFR) of less than 60.0 ml/minute/1.73 m 2 of body-surface area (stage3–5). Kaplan-Meier method was used to compare 5-year survival of diabetic and non-diabetic patients, in the presence (n=337) or absence (n=551). Kaplan-Meier curves for 5-year survival rate are shown in Figure . In the absence of CKD, there was no significant difference in 5-year survival rate between patients with diabetes and those without (93 % v.s. 94 %, p=0.82). In patients with CKD, however, diabetes was associated with lower 5-year survival rate (65 % v.s. 87 %, p<0.001). Multivariate analysis showed that diabetes was an independent predictor for 5-year survival in patients with CKD (OR 3.2, 95%CI 1.8–5.8, p=0.0002), but not in patients without CKD (OR 1.1, 95%CI 0.4–2.5, p=0.82). Diabetes mellitus was an independent predictor for death after AMI in patients with CKD. Aggressive treatment after AMI should be advocated in diabetic patients with CKD.

Rule Out

Abstract Introduction According to ESC guidelines, an acute myocardial infarction (MI) can be excluded without serial troponin measurements in patients presenting with a single high-sensitive troponin below the 99th percentile and chest pain starting >6 hours prior to admission. However, it is unclear if single-testing of high-sensitive troponin can rule-out MI in early presenters. Purpose To investigate the diagnostic performance of a single value of high-sensitive cardiac troponin I (hs-cTnI) at presentation for ruling-out MI in patients presenting with chest pain to the Emergency Department irrespective of chest pain onset. Methods We conducted a substudy of preliminary data from the RACING-MI trial. We included patients presenting with chest pain suggestive of MI to the Emergency Department of a Regional Hospital. We used the Siemens hs-cTnI (Siemens Healthcare, TNIH, Limit of detection: 2.21 ng/L) and a diagnostic cut-off value <3 ng/L to rule-out MI at presentation. Two physicians independently adjudicated the final diagnosis based on all clinical information. Patients were stratified based on time from chest pain onset to hospital admission as very early (0–3 hours), early (3–6 hours) and late presenters (>6 hours). Results We included 989 patients with available hs-cTnI results at admission. MI was confirmed in 82 (8.3%) patients. Using hs-cTnI <3 ng/L as diagnostic cut-off value at presentation, 302 (30.5%) patients without MI were classified as rule-out. Overall, the negative predictive value (NPV) for MI was 100% (95% CI 98.7–100). Based on chest pain onset, 33.8% of patients were classified as very early, 12.8% as early, and 42.7% as late presenters, with 10.7% patients with unreported/unknown onset. NPV was 100% (95% CI 96.5–100) for very early, 100% (95% CI 88.3–100) for early and 100% (95% CI 97.3–100) for late presenters. Conclusions Using a single hs-cTnI value <3ng/L as diagnostic cut-off to rule-out MI seems to be safe and to allow rapid rule-out of MI in patients presenting with chest pain to the emergency department, even in very early presenters.

The Impact

Abstract Background/Introduction Essential thrombocytosis (ET) is a rare disease characterized by vasomotor symptom, thrombotic event, and hemorrhage. Due to its rare occurrence, limited data are available to examine the impact of ET on acute myocardial infarction (AMI). Purpose To evaluate the impact of ET on hospital outcomes of AMI. Methods We use the 2016 National Inpatient sample database to identify all the admissions with a principal diagnosis of AMI with or without ET. A matched control group was then generated using propensity score from age, sex, race, location, insurance, income, hospital type, hospital location, Charlsoncat Comorbidity Score. Prevalence, baseline characteristic of AMI patient with or without ET was described and compared. Univariable logistic regression was used to measure mortality and the rate of catheterization. Results ET was found in 0.28% (1,814) in total AMI admissions (641,854). Age (69.52 vs 69.70), female percentage (48.04% vs 48.03%) and baseline comorbidities including STEMI (27.49% vs 25.08%), diabetes (33.03% vs 30.51%), heart failure (40.18 vs 45.89%) and chronic kidney disease (22.05% vs 26.28%) was found to be comparable between two groups (p>0.05, table 1). Compared to non ET group, ET is associated with significantly higher hospital mortality (5.74% vs 2.43%, OR 2.44 [1.09–5.48], p=0.03), prolonged length of stay (7.61 vs 4.30 days, p<0.01). Interestingly, ET is also associated with lower utilization of cardiac catheterization (37.46% vs 46.52%, p=0.01). Essential Thrombocytosis and AMI Parameter AMI with ET Matched control: AMI without ET Odds ratio (95% CI) P value (n=1,814) (n=1,814) Age, years 69.52±0.72 69.70±0.70 p>0.05 Female, % 48.04 48.03 p>0.05 STEMI, % 27.49 25.08 p>0.05 Hypertension, % 81.57 83.08 p>0.05 Diabetes, % 33.03 30.51 p>0.05 Heart failure, % 40.18 45.89 p>0.05 Chronic kidney disease, % 22.05 26.28 p>0.05 Mortality, % 5.74 2.43 2.44 (1.09–5.48) p=0.03 Catheterization, % 37.46 46.52 0.68 (0.51–0.91) P=0.01 Length of stay, days 7.61±0.48 4.30±0.21 P<0.01 Values are reported as mean ± S.E. Categorical variables are represented as frequency. Conclusion ET is infrequently observed in patients with AMI. Having ET is associated with higher hospital mortality, longer hospital stay and lower utilization of cardiac catheterization. Acknowledgement/Funding None
