A 35-year-old man with multiple cardiovascular risk factors presented with a recent history of fever and acute heart failure. His initial echocardiogram showed evidence of severe aortic regurgitation due to ongoing infective endocarditis. Preoperative coronary angiography revealed no coronary abnormalities. Urgent aortic valve replacement was performed and a 29 mm St Jude mechanical valve was implanted. While blood and resected valvular tissue cultures were negative for bacteria, a PCR-based analysis revealed the presence of penicillin-sensitive Streptococcus pneumoniae. Echocardiographic follow-up study at day 3 showed excellent mechanical valve function with no persistent signs of endocarditis. Eight days after surgery, our patient presented with severe chest pain. The ECG is shown in figure 1A and coronary angiography was performed for diagnostic confirmation (figure 1B-D and online supplementary video 1).DC1SP110.1136/heartjnl-2018-313577.supp1Supplementary file 1 heartjnl;105/3/234/F1F1F1Figure 1(A) 12-lead ECG.

Heart disease (HD) accounts for high morbidity and mortality in Brazil. Underserved populations often suffer long delays in diagnosis. We aimed to evaluate the feasibility of integrating screening echocardiography (echo) with remote interpretation in the established primary care system (PC) in Brazil and to assess HD prevalence. ⋯ Integration focused echo into PC is feasible in Brazil as a strategy to deliver cardiovascular care to low-resourced areas through task shifting. The burden of HD observed suggests this tool may improve early diagnosis and referral.

In the last decade, there has been a rapid increase in the dissemination of automated external defibrillators (AEDs) for prehospital defibrillation of out-of-hospital cardiac arrest patients. The aim of this study was to study the association between different defibrillation strategies on survival rates over time in Copenhagen, Stockholm, Western Sweden and Amsterdam, and the hypothesis was that non-EMS defibrillation increased over time and was associated with increased survival. ⋯ Survivors of out-of-hospital cardiac arrest are increasingly defibrillated by non-EMS AEDs. This increase is primarily due to a large increase in the use of onsite AEDs as well as an increase in first-responder defibrillation over time. Non-EMS defibrillation accounted for at least part of the increase in survival rate of patients with a shockable initial rhythm.

Multicenter Study
Associations of egg consumption with cardiovascular disease in a cohort study of 0.5 million Chinese adults.
To examine the associations between egg consumption and cardiovascular disease (CVD), ischaemic heart disease (IHD), major coronary events (MCE), haemorrhagic stroke as well as ischaemic stroke. ⋯ Among Chinese adults, a moderate level of egg consumption (up to <1 egg/day) was significantly associated with lower risk of CVD, largely independent of other risk factors.

Multicenter Study Observational Study
Characteristics and outcomes of adults with chronic obstructive pulmonary disease and atrial fibrillation.
Chronic obstructive pulmonary disease (COPD) is associated with the development of atrial fibrillation (AF), and may complicate treatment of AF. We examined the association between COPD and symptoms, quality of life (QoL), treatment and outcomes among patients with AF. ⋯ NCT01165710.
