To assess the impact of summer heat waves on key parameters of oxidative stress in patients with coronary heart disease. ⋯ Changes in the key parameters of oxidative stress in patients with ischemic heart disease during summer heat waves are comparable to those in patients without ischemia, however significantly greater inhibition of GSH-Px activity and significantly lower increase in Cu,Zn-SOD activity was noted. These results may indicate misregulation of free radical processes in patients with ischemic heart decease.

[Cardiovascular magnetic resonance in myocardial infarction with non-obstructive coronary arteries].
To analyze diagnostic performance of cardiovascular magnetic resonance (CMR) in patients, presented with myocardial infarction with nonobstructed coronary arteries (MINOCA). Materials ant methods. 46 consecutives patients presented with myocardial infarction without evidence of obstructive coronary disease on angiography between January, 1 2018 and October 1, 2019 were included in the study. All patients underwent CMR within 10 days after admission. MRI was performed on 1.5 T Magnetic Resonance Imaging (MRI) using comprehensive protocol (T2-images, Cine-CMR, late gadolinium enhancement (LGE)). ⋯ Clinical data doesnt allow to differentiate ischemic or non-ischemic causes of MINOCA. However, CMR establish the correct diagnosis in most cases.

Cardiogenic shock is the pathology most commonly encountered by intensive care physicians. Its frequency averages 410% in STEMI (ST-elevation myocardial infarction) patients and 24% in NONSTEMI (non-ST-elevation myocardial infarction) patients. Effective shock therapy is impossible without understanding the hemodynamic mechanisms of its occurrence. ⋯ In this article, the authors emphasize the importance of measuring central hemodynamic parameters in patients with predominantly cardiogenic shock. We have tried to structure the knowledge about different techniques of central hemodynamics monitoring, considered advantages and disadvantages of each of them. We believe that the data obtained by hemodynamic monitoring should be closely studied and used, because sometimes multidirectional mechanisms may be involved in the genesis of shock; therefore, therapy should be based on the data obtained in a particular patient.

To determine the clinical efficacy and safety of the sorbed probiotics Bifidobacterium bifidum 1 (5108 KОЕ) and B. bifidum 1 (5107 KОЕ) in combination with Lactobacillus plantarum 8P-А3 in the complex therapy of pneumonia caused by SARS-CoV-2 in adult patients without severe risk factors. ⋯ The use of sorbed B. bifidum 1 (5108 KОЕ) improved the well-being of patients without risk factors with moderate viral (SARS-CoV-2) pneumonia and reduced the duration of diarrheal syndrome in a short time. The safety profile of their use was high. More research is needed to clarify the anti-inflammatory effects of the sorbed probiotic.

Recently, the role of cardiac magnetic resonance imaging (cardiovascular magnetic resonance) in the diagnosis of coronary artery disease and acute myocardial infarction has increased significantly. This method is defined as the gold standard for differentiation between ischemic vs non-ischemic and acute vs chronic myocardial injury. This part of the review summarizes the main methods of cardiovascular magnetic resonance, its safety, indications and contraindications.
