Aim: Omega-3 fatty acids have emerged as a new option for controlling the residual risk for coronary artery disease (CAD) in the statin era. Eicosapentaenoic acid (EPA) is associated with reduced CAD risk in the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention trial, whereas the Statin Residual Risk with Epanova in High Cardiovascular Risk Patients with Hypertriglyceridemia trial that used the combination EPA/docosahexaenoic acid (DHA) has failed to derive any clinical benefit. These contradictory results raise important questions about whether investigating the antiatherosclerotic effect of omega-3 fatty acids could help to understand their significance for CAD-risk reduction. Methods: The Attempts at Plaque Vulnerability Quantification with Magnetic Resonance Imaging Using Noncontrast T1-weighted Technic EPA/DHA study is a single-center, triple-arm, randomized, controlled, open-label trial used to investigate the effect of EPA/DHA on high-risk coronary plaques after 12 months of treatment, detected using cardiac magnetic resonance (CMR) in patients with CAD receiving statin therapy. Eligible patients were randomly assigned to no-treatment, 2-g/day, and 4-g/day EPA/DHA groups. The primary endpoint was the change in the plaque-to-myocardium signal intensity ratio (PMR) of coronary high-intensity plaques detected by CMR. Coronary plaque assessment using computed tomography angiography (CTA) was also investigated. Results: Overall, 84 patients (mean age: 68.2 years, male: 85%) who achieved low-density lipoprotein cholesterol levels of <100 mg/dL were enrolled. The PMR was reduced in each group over 12 months. There were no significant differences in PMR changes among the three groups in the primary analysis or analysis including total lesions. The changes in CTA parameters, including indexes for detecting high-risk features, also did not differ. Conclusion: The EPA/DHA therapy of 2 or 4 g/day did not significantly improve the high-risk features of coronary atherosclerotic plaques evaluated using CMR under statin therapy.

The American Heart Association (AHA) Scientific Sessions 2016 were held on November 12–16 at the Ernest N. Morial Convention Center, New Orleans, LA. This 5-day event featured cardiovascular clinical practice covering all aspects of basic, clinical, population, and translational content. One of the hot topics at AHA 2016 was precision medicine. The key presentations and highlights from the AHA Scientific Sessions 2016, including “precision medicine” as one of the hot topics, are herein reported.

Background: Acute kidney injury (AKI) and acute hyperglycemia are associated with unfavorable outcomes. The impact of acute hyperglycemia on the development of AKI after acute myocardial infarction (AMI), however, remains unclear. This study was undertaken to assess the relationship between admission glucose and incidence of AKI after AMI. Methods and Results: This study consisted of 760 patients with AMI admitted to the National Cerebral and Cardiovascular Center within 48h after symptom onset. Blood sample was obtained on admission and repeated sampling was done at least every 1 or 2 days during the first week. AKI was diagnosed as increase in serum creatinine ≥0.3mg/dl or ≥50% within any 48h. Ninety-six patients (13%) had AKI during hospitalization for AMI, and these patients had higher in-hospital mortality than those without AKI (25% vs. 3%, P<0.001). Patients with AKI had higher plasma glucose (PG) on admission than those without (222±105mg/dl vs. 166±69mg/dl, P<0.001). The incidence of AKI increased as admission PG rose: 7% with PG <120mg/dl; 9% with PG 120–160mg/dl; 11% with PG 160–200mg/dl; and 28% with PG >200mg/dl (P<0.01). On multivariate analysis admission PG was an independent predictor of AKI (odds ratio, 1.10; 95% confidence interval: 1.03–1.18, P=0.02). Conclusions: Admission hyperglycemia might have contributed to the development of AKI in patients with AMI.  (Circ J 2014; 78: 1475–1480)

Background:According to troponin-based criteria of myocardial infarction (MI), patients without elevation of creatine kinase (CK), formerly classified as unstable angina (UA), are now diagnosed as non-ST-elevation MI (NSTEMI), but little is known about their outcomes.Methods and Results:Between July 2012 and March 2014, 3,283 consecutive patients with MI were enrolled. Clinical follow-up data were obtained up to 3 years. The primary endpoint was a composite of all-cause death, non-fatal MI, non-fatal stroke, cardiac failure and urgent revascularization for UA. There were 2,262 patients with ST-elevation MI (STEMI), 563 NSTEMI with CK elevation (NSTEMI+CK) and 458 NSTEMI without CK elevation (NSTEMI-CK). From day 0, Kaplan-Meier curves for the primary endpoint began to diverge in favor of NSTEMI-CK for up to 30 days. The 30-day event rate was significantly lower in patients with NSTEMI-CK (3.3%) than in STEMI (8.6%, P<0.001) and NSTEMI+CK (9.9%, P<0.001). Later, the event curves diverged in favor of STEMI. The event rate from 31 days to 3 years was significantly lower in patients with STEMI (19.8%) than in NSTEMI+CK (33.6%, P<0.001) and NSTEMI-CK (34.2%, P<0.001). Kaplan-Meier curves from 31 days to 3 years were almost identical between NSTEMI+CK and NSTEMI-CK (P=0.91).Conclusions:Despite smaller infarct size and better short-term outcomes, long-term outcomes of NSTEMI-CK after convalescence were as poor as those for NSTEMI+CK and worse than for STEMI.
