Association between post-procedural hyperoxia and poor functional outcome after mechanical thrombectomy for ischemic stroke: an observational study.

Background: The actual effects of oxygen therapy on patients who have suffered a stroke are still unknown, and its recommendation as a routine measure in emergency services remains controversial. The aim of this study is to determine the effect of hyperoxia in functional recovery in patients with ischemic stroke who underwent intra-arterial mechanical thrombectomy (IAMT).

Methods: A prospective observational cohort study that included all adult patients consecutively admitted to the intensive care unit (ICU) due to an ischemic stroke in the anterior cerebral circulation and following an IAMT intervention, between 2010 and 2015.

[Preliminary experience in an intensive care unit with Impella Recover. A new circulatory support system in patients with low cardiac output].

The low cardiac output syndrome following cardiopulmonary bypass is characterized by poor left ventricular contractibility that requires the support of high doses of vasoactive drugs, intra-aortic balloon pump, and sometimes makes it impossible to disconnect the extracorporeal circulation. We report 5 cases in which a "recently created" device in left ventricular support was inserted, the Impella Recover (Impella CardioSystems AG, Aachen, Germany) due to cardiogenic shock at the end of the surgery. Four of these patients recovered their heart function and the ventricular support could be removed after 70+/-55 h.

[Prognosis of presyncope in patients with structural heart disease].

Introduction And Objectives: Few data are available on the prognosis of presyncope in patients with structural heart disease. The aim of this study was to compare the clinical characteristics and long-term prognosis of patients with structural heart disease admitted for presyncope or syncope in the cardiology department of a tertiary hospital.

Methods: We reviewed the medical records of 449 patients (65% men, mean age 66.

[Head-up tilt test potentiated with nitroglycerin. What is the optimal duration of the test after administration of the drug?].

Introduction And Objectives: Numerous variations of the head-up tilt-table test potentiated with nitrates have been reported. After the administration of nitroglycerin, between 10 and 25 min of continued tilting have been recommended. The aim of this study was to assess the optimal duration of the pharmacological phase of the head-up tilt-table test potentiated with sublingual administration of nitroglycerin spray (NTG-TT).
