Short-Term Effect of Nutraceutical Fruit Juices on Lipid Metabolism in Patients with Acquired Hypercholesterolemia.

The crucial role of dyslipidaemia, especially hypercholesterolemia, in the development of atherosclerosis-related cardiovascular diseases has been extensively documented in genetic, pathologic, observational and intervention studies. The European guidelines for dyslipidaemia management include the possible use of lipid-lowering nutraceuticals to support a relatively large number of natural compounds. In this context, we have conducted a study to investigate whether dietary supplementation with a functional nutraceutical beverage, containing a standardized polyphenolic fraction from fruit, red yeast rice, phytosterols, and berberine complexed with ß-cyclodextrin, could positively affect serum lipid concentration in 14 subjects with hypercholesterolemia. After 12 weeks of treatment, dietary supplementation with this nutraceutical combination was associated with significant improvements in total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C) and apolipoprotein B, compared to baseline. Compliance was excellent and no adverse effects were reported. In conclusion, this study demonstrates that 100 mL of a functional beverage containing lipid-lowering nutraceuticals safely leads to significant improvements in serum lipids in subjects with moderate hypercholesterolemia. Future research is needed to unravel the role that the polyphenols contained in fruit extracts play in the reduction of cholesterolemia and in cardiovascular disease prevention.

Clinically significant bleeding with low-dose rivaroxaban versus aspirin, in addition to P2Y12 inhibition, in acute coronary syndromes (GEMINI-ACS-1): a double-blind, multicentre, randomised trial.

BACKGROUND: Dual antiplatelet therapy (DAPT), aspirin plus a P2Y12 inhibitor, is the standard antithrombotic treatment following acute coronary syndromes. The factor Xa inhibitor rivaroxaban reduced mortality and ischaemic events when added to DAPT, but caused increased bleeding. The safety of a dual pathway antithrombotic therapy approach combining low-dose rivaroxaban (in place of aspirin) with a P2Y12 inhibitor has not been assesssed in acute coronary syndromes. We aimed to assess rivaroxaban 2·5 mg twice daily versus aspirin 100 mg daily, in addition to clopidogrel or ticagrelor (chosen at investigator discretion before randomisation), for patients with acute coronary syndromes started within 10 days after presentation and continued for 6-12 months. METHODS: In this double-blind, multicentre, randomised trial (GEMINI-ACS-1) done at 371 clinical centres in 21 countries, eligible patients were older than 18 years with unstable angina, non-ST segment elevation myocardial infarction (NSTEMI) or ST segment elevation myocardial infarction (STEMI), with positive cardiac biomarkers and either ischaemic electrocardiographic changes or an atherosclerotic culprit lesion identified during angiography. Participants were randomly assigned (1:1) within 10 days after admission for the index acute coronary syndromes event to either aspirin or rivaroxaban based on a computer-generated randomisation schedule. Randomisation was balanced by using randomly permuted blocks with size of four and was stratified based on the background P2Y12 inhibitor (clopidogrel or ticagrelor) intended to be used at the time of randomisation. Investigators and patients were masked to treatment assignment. Patients received a minimum of 180 days of double-blind treatment with rivaroxaban 2·5 mg twice daily or aspirin 100 mg daily. The choice of clopidogrel or ticagrelor during trial conduct was not randomised and was based on investigator preference. The primary endpoint was thrombolysis in myocardial infarction (TIMI) clinically significant bleeding not related to coronary artery bypass grafting (CABG; major, minor, or requiring medical attention) up to day 390. Primary analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT02293395. FINDINGS: Between April 22, 2015, and Oct 14, 2016, 3037 patients with acute coronary syndromes were randomly assigned; 1518 to receive aspirin and 1519 to receive rivaroxaban. 1704 patients (56%) were in the ticagrelor and 1333 (44%) in the clopidogrel strata. Median duration of treatment was 291 days (IQR 239-354). TIMI non-CABG clinically significant bleeding was similar with rivaroxaban versus aspirin therapy (total 154 patients [5%]; 80 participants [5%] of 1519 vs 74 participants [5%] of 1518; HR 1·09 [95% CI 0·80-1·50]; p=0·5840). INTERPRETATION: A dual pathway antithrombotic therapy approach combining low-dose rivaroxaban with a P2Y12 inhibitor for the treatment of patients with acute coronary syndromes had similar risk of clinically significant bleeding as aspirin and a P2Y12 inhibitor. A larger, adequately powered trial would be required to definitively assess the efficacy and safety of this approach. FUNDING: Janssen Research & Development and Bayer AG.

Networks for improving care in patients with acute coronary syndrome: A framework.

In recent years, it has become evident that the level of guideline adherence in patients presenting with acute coronary syndrome (ACS) is highly correlated with patient outcomes. Unfortunately, guideline adherence is low in some geographic areas and especially in those patients at high-risk. Regional networks including ambulance systems and hospitals with catheterization laboratories are able to increase guideline adherence and patient outcomes by streamlining the critical pre- and intra-hospital processes as well as improving timely access to invasive procedures and recommended medication. Successful organization of an ACS network requires engagement of multiple stakeholders to create effective solutions for the specific local setting. There is no 'one-size-fits all' strategy to set-up and successfully run an ACS network. We present a framework for how to set up and organize an effective ACS network, delivering guideline-based care to improve patient outcomes.

Transfer times and outcomes in patients with ST-segment-elevation myocardial infarction undergoing interhospital transfer for primary percutaneous coronary intervention: APEX-AMI insights.

BACKGROUND: Transfer delays for primary percutaneous coronary intervention may increase mortality in patients with ST-segment-elevation myocardial infarction. We examined the association between door 1-to-door 2 (D1D2) time, a measure capturing the entire transfer process, and outcomes in patients undergoing interhospital transfer for primary percutaneous coronary intervention. METHODS AND RESULTS: We evaluated the relationship between D1D2 time and the 90-day incidence of death, shock, and heart failure in the subset of 2075 (36.1%) of 5745 patients who underwent interhospital transfer for primary percutaneous coronary intervention in the Assessment of Pexelizumab in Acute Myocardial Infarction trial. There was no significant difference in the 90-day incidence of death, shock, and heart failure between the transferred and the nontransferred groups (10.3% versus 10.2%; P = 0.89). The median difference in symptom-to-balloon time between the 2 groups was 45 minutes (229 versus 184; P<0.001). The primary outcome per 30-minute delay was higher for patients with a D1D2 time ≤150 minutes (hazard ratio, 1.19: 95% confidence interval, 1.06 to 1.33; P = 0.004) but not for D1D2 times >150 minutes (hazard ratio, 0.99: 95% confidence interval, 0.96 to 1.02; P = 0.496). The association between longer D1D2 time and worsening outcome was no longer statistically significant after multivariable adjustment. CONCLUSIONS: Longer transfer times were associated with higher rate of death, shock, and heart failure among patients undergoing interhospital transfer from primary percutaneous coronary intervention, although this difference did not persist after adjusting for baseline characteristics.
