Global Systolic Function

A 78-year-old woman presented herself at emergency for the appearance of severe dyspnea. An electrocardiogram showed signs of inferior and anterior necrosis, and laboratory tests showed a small increase of myocardial cytonecrosis enzymes. An echocardiogram detected a reduction of global systolic function (ejection fraction [EF] approximately 40%) as well as akinesia of the apex, interventricular septum middle segments, and anterior and anterolateral walls, with basal segments showing compensatory hyperkinesia. The coronarography showed a coronary tree substantially free from significant lesions. The patient was transferred to the cardiology unit of our hospital. Based on the contained increase of the cardiac enzymes, the absence of coronary lesions, and the presence of typical echocardiography alterations, we suspected a Tako-tsubo-like syndrome. On deeper anamnestic investigation, an event of strong emotional stress emerged preceding the hospital admission that confirmed the pathology, even though it is atypical to see clinical presentation a long time after a stressful event.

The ternary Co–Mo–W(Zr) coatings with total content of refractory metals of 30–40 wt.%, and Co–W–Zr alloys (12–26 wt.%) are deposited from pyrophosphate-citrate electrolytes in pulse regime. The composition of the coatings as well as the surface morphology depends on the current density. The X-ray diffraction patterns reflect the amorphous-and-crystalline ternary alloys structure. Phases of α-Co, Co–Mo intermetallic compounds, and traces of metallic molybdenum were detected in the Co–Mo–Zr coatings. Phase composition of Co–Mo–W deposits differs by emergence of Co7W6 phase and traces of metallic tungsten, and there is no metallic W in Co–W–Zr electrolytic alloys. The corrosion behavior of ternary coatings in alkaline medium studied by EIS shows that Co–Mo–Zr alloys are characterized by highest corrosion resistance among deposited coatings due to presence of metallic molybdenum and stoichiometric ZrO2 with both high electrical resistivity and chemical stability. The coatings  Co–Mo–W and Co–Mo–Zr containing phases of Mo or W are characterized by higher corrosion resistance as compared with that without metallic molybdenum and tungsten. The cyclic voltammetry data confirm stability of ternary coatings in alkaline solution under anodic polarization. Such properties as well as the developed globular surface make materials promising for use as anodes in fuel cells in particular based on alkali electrolytes.
