Systemic right ventricular (RV) function is a major determinant of long-term outcome in patients with palliated hypoplastic left heart syndrome (HLHS). Abnormal elastic properties of the reconstructed aorta may negatively impact on ventricular function. We therefore aimed to assess arterial elastance and its relationship to systemic RV function in these patients. ⋯ Arterial elastance is abnormally high in palliated HLHS patients and negatively impacts on ejection fraction but not on intrinsic systolic RV function early after completion of the Fontan circulation. Increased arterial elastance, however, is associated with increased RV diastolic stiffness with potential adverse effects on long-term outcome. Furthermore, arterial elastance and diastolic stiffness are particularly high in patients who needed treatment for aortic arch obstruction.

ESC guidelines recommend a shorter (90 min) delay for the use of primary percutaneous intervention (pPCI) in patients presenting within the first 2h of pain onset. Using registry data on STEMI patients in the Greater Paris Area, we assessed changes between 2003 and 2008 in the rates of pPCI, pre-hospital fibrinolytic therapy (PHF) and time delays in patients presenting within 2h of STEMI pain onset. ⋯ In areas with a low density of pPCI centers, efforts should be made to improve the timeliness of pPCI. Otherwise, PHF followed by an immediate transfer to a pPCI capable hospital may be considered.

Multicenter Study
Rheumatoid arthritis and risk of acute myocardial infarction--a nationwide retrospective cohort study.
Rheumatoid arthritis (RA) imposes substantial social costs, including an increased risk of work-related disability and accelerated cardiovascular diseases. The aim of the study is to determine the risk of acute myocardial infarction (AMI) associated with RA in a nationwide retrospective cohort study. ⋯ This nationwide retrospective cohort study indicates that AMI risk increased by 38% in RA patients compared to the general population. Comorbidities increase the AMI risk independently.
