There is growing evidence that transradial (TRI) as compared to transfemoral (TFI) percutaneous coronary intervention (PCI) is associated with improved clinical outcome driven by less hemorrhagic complications, in particular in STEMI patients receiving aggressive antithrombotic treatment. Feasibility rate of TRI in STEMI patients has not yet been evaluated. ⋯ In STEMI patients without cardiogenic shock and without a priori indication for TFI, PCI can be performed via the radial artery in more than 90% of cases with high procedural success rate. Operator's judgement of eligibility for TRI based on radial pulse quality is predictive of successful TRI in 95% of cases. TR failure is significantly more common in the elderly and in patients with low body weight.

There is a need for reliable prognostic parameters in pulmonary arterial hypertension (PAH), especially in children. Pulsatile components of the right ventricular afterload, represented by pulmonary arterial compliance (PACi) and pulmonary stroke volume (PSVi), may provide important additional prognostic information to conventional static haemodynamic parameters. The aim of this study was to determine the prognostic value of PACi and PSVi in paediatric PAH. ⋯ The parameters of both the pulsatile and static pulmonary circulations are strong independent predictors for transplant-free survival, and therefore can be of complementary value in assessing disease severity, predicting survival and guiding treatment in paediatric PAH.

Observational Study
Prognosis and treatment in patients admitted with acute myocardial infarction on weekends and weekdays from 1997 to 2009.
Less invasive treatment and poorer outcomes have been shown among patients admitted with acute myocardial infarction (AMI) on weekends compared to weekdays. ⋯ No persistent 'weekend-effect' on mortality was present in patients with AMI in 1997-2009. Overall, mortality rates have decreased concomitantly with an increased use of current guideline-recommended invasive and medical therapy.
