[Ethical aspects in the context of extracorporeal life support systems (ECLS): consensus paper of the DGK, DGTHG and DGAI].

Extracorporeal life support systems (ECLS) are life-sustaining measures for severe cardiovascular diseases, serving as bridging treatment either until cardiovascular function is restored or alternative treatment, such as heart transplantation or the implantation of permanent ventricular assist devices is performed. Given the insufficient evidence and frequent urgency of implantation without initial patient consent, the ethical challenges and psychological burden for patients, relatives and the interprofessional intensive care team are significant. As with any treatment, an appropriate therapeutic goal for ECLS treatment based on the indications and patient informed consent is mandatory.

Left ventricular structure and function following renal sympathetic denervation in patients with HFpEF: an echocardiographic 9-year long-term follow-up.

Background: High blood pressure is a major risk factor for cardiac remodeling and left ventricular hypertrophy, increasing cardiovascular risk and leading to heart failure with preserved ejection fraction (HFpEF). Since renal sympathetic denervation (RDN) reduces blood pressure in the long term, we aimed to investigate the long-term effect of RDN in patients with HFpEF in the present analysis.

Methods: Patients previously enrolled in a local RDN registry who underwent high-frequency RDN with the use of the Symplicity Flex® renal denervation system between 2011 and 2014 were followed up.

German Cardiac Arrest Registry (G-CAR)-results of the pilot phase.

Background: In Europe, more than 300,000 persons per year experience out-of-hospital cardiac arrest (OHCA). Despite medical progress, only few patients survive with good neurological outcome. For many issues, evidence from randomized trials is scarce.

Intermittent Fasting After ST-Segment-Elevation Myocardial Infarction Improves Left Ventricular Function: The Randomized Controlled INTERFAST-MI Trial.

Background: Intermittent fasting has shown positive effects on numerous cardiovascular risk factors. The INTERFAST-MI trial (Intermittent Fasting in Myocardial Infarction) has been designed to study the effects of intermittent fasting on cardiac function after STEM (ST-segment-elevation myocardial infarction) and the feasibility of future multicenter trials.

Methods: The INTERFAST-MI study was a prospective, randomized, controlled, nonblinded, single-center investigator-initiated trial.

Isolation of circulating endothelial cells provides tool to determine endothelial cell senescence in blood samples.

Circulating endothelial cells (CEC) are arising as biomarkers for vascular diseases. However, whether they can be utilized as markers of endothelial cell (EC) senescence in vivo remains unknown. Here, we present a protocol to isolate circulating endothelial cells for a characterization of their senescent signature.
