Pandemic influenza particularly often is associated with symptoms of acute respiratory failure, and in case of refractory hypoxemia patients may have indications for the extracorporeal membrane oxygenation (ECMO). The paper presents a case of a pandemic influenza virus infection, where classical indications for veno-venous ECMO occured. Practical aspects of this kind of treatment in the intensive care unit are discussed.

Spinal cord stimulation (SCS) is a well known method of treatment used worldwide since the 80's of the last century. High efficiency of SCS was observed in the treatment of various types of pain. Promising clinical results were observed in the treatment of patients with refractory angina (RA). ⋯ The mechanism of action in RA is not well understood. It is known that SCS reduces the activity of the sympathetic nervous system, by which improves the coronary perfusion and oxygenation of the heart muscle. It is important that SCS does not mask the pain related to the infarct.

Acute heart failure (HF) is an emerging problem in clinical practice, associated with high in-hospital mortality and a high short-term readmission rate. ⋯ In our registry, in-hospital mortality in patients admitted due to acute HF was slightly higher compared to other reports. Baseline values of some parameters (e.g. blood pressure, serum Na(+), renal function) as well as their changes during hospitalisation (e.g. serum K(+), renal function, plasma NT-proBNP) can help identify acute HF patients at a higher risk of in-hospital mortality.

Cardiac surgery is associated with ischaemic and reperfusion injury to the myocardium. It seems natural to seek a possibility of inducing the natural endoprotective mechanisms known as myocardial conditioning, including preconditioning, postconditioning, and remote conditioning. Still, in spite of almost 20 years of research in the field, we are far from routine widespread usage of these methods, with published reports describing quite various, and often contradictory results. Current review summarises the trials of using the conditioning in cardiac surgical practice including pharmacological manipulations to induce resistance to ischaemia-reperfusion.

Wellens syndrome is characterised by negative or biphasic T waves in V2-V4 leads and critical stenosis of proximal part of the left descending coronary artery. These ECG changes without atherosclerotic changes in coronary angiography, i.e. coronary artery spasm are called pseudo-Wellens syndrome. We describe a patient with acute coronary syndrome and pseudo-Wellens syndrome as a cause of vasospastic angina. These ECG abnormalities need differentiation with acute pulmonary embolism.
