Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used and have been associated with increased cardiovascular risk. Nonetheless, it remains unknown whether use of NSAIDs is associated with out-of-hospital cardiac arrest (OHCA).

Patient response to statin treatment is individual and varied. As a consequence, when using a specific-dose approach, as recommended in the 2013 American College of Cardiology/American Heart Association guideline, there will be a range of reductions in the concentration of low-density lipoprotein cholesterol (LDL-C). The aim of this study was to use individual patient data from the VOYAGER meta-analysis to determine the extent of the variability in LDL-C reduction in response to treatment across the recommended doses of different statins.

Long-term prognostic impact of coronary artery disease (CAD) severity in stable post-myocardial infarction (MI) patients is not well known. We examined the impact of CAD severity and co-morbidity on the long-term (1 year and beyond) risk of cardiovascular events post-MI.

The very high occurrence of cardiovascular events presents a major public health issue because treatment remains suboptimal. Lowering low-density lipoprotein cholesterol (LDL-C) with statins or ezetimibe in combination with a statin reduces major adverse cardiovascular events. The cardiovascular risk reduction in relation to the absolute LDL-C reduction is linear for most interventions without evidence of attenuation or increase in risk at low LDL-C levels. Opportunities for innovation in dyslipidaemia treatment should address the substantial risk of lipid-associated cardiovascular events among patients optimally treated per guidelines but who cannot achieve LDL-C goals, could benefit from additional LDL-C lowering therapy, or experience side effects of statins. Fresh approaches are needed to identify promising drug targets early and develop them efficiently. The Cardiovascular Round Table of the ESC convened a workshop to discuss new lipid lowering strategies for cardiovascular risk reduction. Opportunities to improve treatment approaches and the efficient study of new therapies were explored. Circulating biomarkers may not be fully reliable proxy indicators of the relationship between treatment effect and clinical outcome. Mendelian randomization studies may better inform development strategies and refine treatment targets before phase 3. Trials should match the drug to appropriate lipid and patient profile, and guidelines may move towards a precision-based approach to individual patient management. Stakeholder collaboration is needed to ensure continued innovation and better international coordination of both regulatory aspects and guidelines. It should be noted that risk may also be addressed through increased attention to other risk factors such as smoking, hypertension, overweight, and inactivity.

Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients with myocardial infarction and atrial fibrillation is uncertain. In this study, we compared antithrombotic regimes with regard to a composite cardiovascular outcome of all-cause mortality, myocardial infarction or ischaemic stroke and major bleeds.

BackgroundThe degree and time course of platelet inhibition using ticagrelor can vary during the acute phase and the following stable period after acute myocardial infarction (AMI). The optimal level of platelet inhibition during the various stages of AMI remains an open question. The aim of the current study is to compare the antiplatelet efficacy of two ticagrelor maintenance dose regimens (60 mg b.i.d. vs 90 mg b.i.d.) in stable patients following an initial strategy with ticagrelor 90 mg b.i.d. during the first month after AMI.MethodsThe ELECTRA pilot study is a phase III, single-center, randomized, open-label, pharmacokinetic/pharmacodynamic trial. The study population will include 50 patients with AMI treated with percutaneous coronary intervention. At day 30 post-AMI, all trial participants will be randomly assigned in 1:1 ratio to receive either reduced (60 mg b.i.d.) or standard (90 mg b.i.d.) maintenance ticagrelor dose until day 45 post-AMI. Platelet function testing in each patient will be performed using up to two different methods (the VASP assay, multiple electrode aggregometry). Pharmacokinetics of ticagrelor and its active metabolite (AR-C124910XX) will be assessed by liquid chromatography mass spectrometry.ConclusionA de-escalation strategy with reduced dose of ticagrelor (60 mg twice daily) following an initial standard dose (90 mg twice daily) during the first month after AMI may provide equally effective platelet inhibition as compared to maintenance with the standard ticagrelor dose.ClinicalTrials.gov Identifier:NCT03251859.

Pericarditis is a debilitating condition that results from profound inflammation of the pericardial tissue. Between 10-15% of first episodes of acute pericarditis will be followed by several episodes refractory to conventional treatment. Current standard of care for pericarditis treatment includes high-dose non-steroidal anti-inflammatory drugs, colchicine and systemic corticosteroids, each associated with potentially severe toxicities and nominal efficacy. Interleukin-1 (IL-1), an apical pro-inflammatory cytokine, plays an important role as an autocrine magnifier of systemic inflammation in pericarditis. Interruption of the IL-1 circuit has been shown to have a favorable risk profile in several disease states. In this review, we discuss the growing body of evidence which supports the use of IL-1 blockade in the treatment of recurrent pericarditis as well as provide practical considerations for the use of IL-1 blockade in clinical practice.

Loop diuretics are recommended for relieving symptoms and signs of congestion in patients with chronic heart failure and are administered to more than 80% of them. However, several of their effects have not systematically been studied. Numerous cohort and four interventional studies have addressed the effect of diuretics on renal function; apart from one prospective study, which showed that diuretics withdrawal is accompanied by increase in some markers of early-detected renal injury, all others converge to the conclusion that diuretics receipt, especially in high doses is associated with increased rates of renal dysfunction. Although a long standing perception has attributed a beneficial effect to diuretics in the setting of chronic heart failure, many cohort studies support that their use, especially in high doses is associated with adverse outcome. Several studies have used propensity scores in order to match diuretic and non-diuretic receiving patients; their results reinforce the notion that diuretics use and high diuretics dose are true risk factors and not disease severity markers, as some have suggested. One small, randomized study has demonstrated that diuretics decrease is feasible and safe and accompanied by a better prognosis. In conclusion, until elegantly designed, randomized trials, powered for clinical endpoints answer the unsettled issues in the field, the use of diuretics in CHF will remain subject to physicians' preferences and biases and not evidence-based.

Hypertension (HTN) is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease (CAD), stroke, peripheral artery disease and chronic renal failure. Hypertensive heart disease can manifest as many types of cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in HTN patients, especially in those with left ventricular hypertrophy (LVH), CAD or HF. In addition, high doses of thiazide diuretics commonly used to treat hypertension, may result in electrolyte abnormalities (eg. hypokalaemia, hypomagnesaemia), contributing further to arrhythmias, while effective Blood pressure control may prevent the development of the arrhythmias such as AF.In recognizing this close relationship between HTN and arrhythmias, the European Heart Rhythm Association (EHRA) and the European Society of Cardiology (ESC) Council on Hypertension convened a Task Force, with representation from the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS) and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE), with the remit of comprehensively reviewing the available evidence and publishing a joint consensus document on HTN and cardiac arrhythmias, and providing up-to-date consensus recommendations for use in clinical practice. The ultimate judgment on the care of a specific patient must be made by the healthcare provider and the patient in light of all individual factors presented. This is an executive summary of the full document co-published by EHRA in EP-Europace.
