Practice Guideline
[Cardiovascular assessment and management prior to non-cardiac surgery : Comment on the new 2014 ESC/ESA guidelines].
In 2014 the European Society of Cardiology (ESC) and the European Society of Anaesthesiology (ESA) published an update of the guidelines on "non-cardiac surgery: cardiovascular assessment and management". Epidemiological data underline the relevance of these guidelines: a total of 5.7 million surgical procedures are performed per year in patients with increased cardiac risk and approximately 167,000 cardiac complications occur per year in Europe of which 19,000 are life-threatening. ⋯ A standardized stepwise approach on how to stratify patient-specific and procedure-associated risks has been established. For the first time, the guidelines recommend perioperative regimens on dual antiplatelet therapy and the new oral anticoagulants (NOAC).

Practice Guideline
[Diagnosis and management of acute pulmonary embolism. ESC guidelines 2014].
Acute pulmonary embolism (PE) still represents a challenge regarding a rapid diagnosis and a risk-adapted therapy. In the 2014 guidelines of the European Society of Cardiology (ESC) on the diagnosis and management of acute PE, several new recommendations have been issued based on new study data. Some established scores for risk stratification were developed further and there is now good evidence for the use of age-adjusted D-dimer cut-off levels. ⋯ For the treatment of patients with venous thromboembolism with or without PE, the non-vitamin K-dependent oral anticoagulants (NOACs) are a safe alternative to the standard anticoagulation regimen with heparin and vitamin K antagonists. Systemic thrombolytic therapy should be restricted to patients with high risk or intermediate high risk with hemodynamic instability. Finally, new recommendations for the diagnosis and therapy of patients with chronic thromboembolic pulmonary hypertension (CTEPH), with cancer or during pregnancy are given.

Review
[Rise of the machines? : Left ventricular assist devices for treatment of severe heart failure].
The use of left ventricular assist devices (LVAD) as a treatment for severe heart failure has gained momentum in recent years. Even at this stage the number of worldwide LVAD implantations far exceeds the volume of heart transplantations in view of the chronic shortage of donor organs. Third generation continuous flow assist devices have helped to improve survival, quality of life and symptom burden of heart failure patients in comparison to a regimen of optimal medication management. ⋯ A careful patient selection process is crucial for a good clinical outcome after device implantation and risk assessment for postoperative right ventricular failure is of particular importance in this context. The rate of hospitalization during LVAD support is still high, despite the step-wise attempts to widen the indications to less severely ill heart failure patients. An effective perioperative and postoperative management will help to lower the incidence of complications (e.g. bleeding, infections, thromboembolic events and right ventricular failure) and to improve the encouraging results of mechanical circulatory support.

Controlled Clinical Trial
Serum NT-proBNP on admission can predict ST-segment resolution in patients with acute myocardial infarction after primary percutaneous coronary intervention.
The aim of this study was to investigate the value of initial serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations in ST-segment elevation myocardial infarction (STEMI) patients for predicting ST-segment resolution (STR) after primary percutaneous coronary intervention (pPCI). ⋯ Serum NT-proBNP concentrations in STEMI patients on hospital admission were useful in predicting non-STR after pPCI.

The new oral anticoagulants (NOAC) dabigatran etexilate, rivaroxaban, and apixaban show similar efficacy for stroke prevention in patients with atrial fibrillation (AF) as the vitamin K antagonist warfarin. Absorption of NOACs is dependent on the intestinal P-glycoprotein (P-gp) system and P-gp activity is modulated by a variety of drugs and food components. ⋯ There is an urgent need to investigate the role of P-gp-modulating substances as potential sources of drug-drug and drug-food interactions. A thorough analysis of the data accumulated in the three large NOAC trials regarding the role of P-gp-modulating drugs in bleeding and embolic events is desirable. Pharmacological studies should investigate the influence of P-gp-modulating drugs and food on NOAC plasma concentrations and coagulation parameters. When prescribing NOACs, patients should be informed about the potential interactions with drugs and herbal drugs. Patients who develop bleeding or embolic events under treatment with NOACs should be investigated for co-medications as well as for over-the-counter drugs and dietary habits. In post-marketing surveillance of NOACs, the association with drug or food intake with complications, bleeding, and embolic events should be registered.
