CXCR2 Inhibition - a novel approach to treating CoronAry heart DiseAse (CICADA): study protocol for a randomised controlled trial.

Background: There is emerging evidence of the central role of neutrophils in both atherosclerotic plaque formation and rupture. Patients with lower neutrophil counts following acute coronary syndromes tend to have a greater coronary flow reserve, which is a strong predictor of long-term cardiovascular health. But so far, no data are available regarding the impact of neutrophil inhibition on cardiovascular clinical or surrogate endpoints.

Prioritizing echocardiography in Staphylococcus aureus bacteraemia.

Objectives: Infective endocarditis (IE) is a severe complication in Staphylococcus aureus bacteraemia (SAB) and recent guidelines from the BSAC recommend all patients undergo echocardiography. We assessed the use of echocardiography at a major tertiary referral centre and sought to identify those patients most likely to have positive findings.

Methods: We retrospectively evaluated all cases of SAB at Oxford University Hospitals NHS Trust between September 2006 and August 2011.

Maintenance of sinus rhythm with an ablation strategy in patients with atrial fibrillation is associated with a lower risk of stroke and death.

Objective: To investigate whether catheter ablation of atrial fibrillation (AF) reduces stroke rate or mortality.

Methods: An international multicentre registry was compiled from seven centres in the U.K.
