Abstract Background: We assessed the value of cystatin C for improvement of risk stratification in patients with non–ST elevation acute coronary syndrome (nSTE-ACS) and increased cardiac troponin T (cTnT), and we compared the long-term effects of an early invasive treatment strategy (EIS) with a selective invasive treatment strategy (SIS) with regard to renal function. Methods: Patients (n = 1128) randomized to an EIS or an SIS in the ICTUS trial were stratified according to the tertiles of the cystatin C concentration at baseline. The end points were death within 4 years and spontaneous myocardial infarction (MI) within 3 years. Results: Mortality was 3.4%, 6.2%, and 13.5% in the first, second, and third tertiles, respectively, of cystatin C concentration (log-rank P < 0.001), and the respective rates of spontaneous MI were 5.5%, 7.5%, and 9.8% (log-rank P = 0.03). In a multivariate Cox regression analysis, the cystatin C concentration in the third quartile remained independently predictive of mortality [hazard ratio (HR), 2.04; 95% CI, 1.02–4.10; P = 0.04] and spontaneous MI (HR, 1.95; 95% CI, 1.05–3.63; P = 0.04). The mortality rate in the second tertile was lower with the EIS than with the SIS (3.8% vs 8.7%). In the third tertile, the mortality rates with the EIS and the SIS were, respectively, 15.0% and 12.2% (P for interaction = 0.04). Rates of spontaneous MI were similar for the EIS and the SIS within cystatin C tertiles (P for interaction = 0.22). Conclusions: In patients with nSTE-ACS and an increased cTnT concentration, mild to moderate renal dysfunction is associated with a higher risk of death and spontaneous MI. Use of cystatin C as a serum marker of renal function may improve risk stratification.

Elevation Acute Coronary Syndrome

Background— An invasive treatment strategy improves outcome in patients with non–ST-elevation acute coronary syndrome at moderate to high risk. We hypothesized that the circulating level of growth differentiation factor 15 (GDF-15) may improve risk stratification. Methods and Results— The Fast Revascularization during InStability in Coronary artery disease II (FRISC-II) trial randomized patients with non–ST-elevation acute coronary syndrome to an invasive or conservative strategy with a follow-up for 2 years. GDF-15 and other biomarkers were determined on admission in 2079 patients. GDF-15 was moderately elevated (between 1200 and 1800 ng/L) in 770 patients (37.0%), and highly elevated (>1800 ng/L) in 493 patients (23.7%). Elevated levels of GDF-15 independently predicted the risk of the composite end point of death or recurrent myocardial infarction in the conservative group ( P =0.016) but not in the invasive group. A significant interaction existed between the GDF-15 level on admission and the effect of treatment strategy on the composite end point. The occurrence of the composite end point was reduced by the invasive strategy at GDF-15 levels >1800 ng/L (hazard ratio, 0.49; 95% confidence interval, 0.33 to 0.73; P =0.001), between 1200 and 1800 ng/L (hazard ratio, 0.68; 95% confidence interval, 0.46 to 1.00; P =0.048), but not <1200 ng/L (hazard ratio, 1.06; 95% confidence interval, 0.68 to 1.65; P =0.81). Patients with ST-segment depression or a troponin T level >0.01 μg/L with a GDF-15 level <1200 ng/L did not benefit from the invasive strategy. Conclusions— GDF-15 is a potential tool for risk stratification and therapeutic decision making in patients with non–ST-elevation acute coronary syndrome as initially diagnosed by ECG and troponin levels. A prospective randomized trial is needed to validate these findings.

Coronary Syndrome

Background: Chronic kidney disease is a frequent comorbidity among patients with acute coronary syndrome (ACS). We aimed to evaluate treatment characteristics in ACS patients according to their renal function and to assess the effect of differences in therapy on clinical outcomes. Methods: Included were patients with ACS enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) during 2000-2013. Excluded were patients with cardiogenic shock at presentation. The estimated glomerular filtration rate (eGFR) was calculated using the simplified Modification of Diet in Renal Disease (MDRD) formula. The distribution of the eGFRs was divided into 4 categories (<45, 45-59.9, 60-74.9, and ≥75 mL/min/1.73 m2). The primary endpoint was all-cause mortality at 1 year. Results: A total of 13,194 patients with ACS were included. Patients with a reduced eGFR were less likely to be admitted to a coronary care unit and had lower rates of coronary angiograms and subsequent percutaneous coronary interventions. Furthermore, as the eGFR was lower, the patients were less frequently treated with aspirin, clopidogrel, β-blockers, and ACE inhibitors/angiotensin receptor blockers. We demonstrated an inverse association between renal function and 1-year mortality, with the highest mortality rates observed in the group with the lowest eGFR (HR = 3.8, 95% CI 2.9-4.9, p < 0.0001). Differences in mortality remained significant following a multivariate analysis for all the baseline characteristics as well as for invasive and medical treatment (HR = 2.7, 95% CI 1.9-3.7, p < 0.0001). Conclusions: ACS patients with chronic kidney disease represent a high-risk group with an increased mortality risk. Despite this high risk, these patients are less frequently selected for an invasive treatment strategy and are less commonly treated with guideline-based medications. However, reduced renal function was associated with higher mortality regardless of the variations in therapy.

Elevation Acute Coronary Syndrome

Background: It is not yet investigated whether referral decisions based on prehospital risk stratification of non-ST-elevation Acute Coronary Syndrome (NSTE-ACS) by the complete History, ECG, Age, Risk factors and initial Troponin (HEART) score are feasible and safe. Hypothesis: Implementation of referral decisions based on the prehospital acquired HEART score in patients with suspected NSTE-ACS is feasible and not inferior to routine management in the occurrence of major adverse cardiac events within 45 days. Study design & methods: FamouS Triage 3 is a feasibility study with a before–after sequential design. The aim is to assess whether prehospital HEART-score management including point-of-care troponin measurement is feasible and noninferior to routine management. Primary end point is the occurrence of major adverse cardiac events within 45 days. Conclusion: If referral decisions based on prehospital acquired risk stratification are feasible and noninferior this can become the new prehospital management in suspected NSTE-ACS.
