Overview of the distal radial access from the radial artery occlusion perspective.

Conventional radial access in endovascular surgery has certain limitations, primarily associated with the presence of local complications and radial artery occlusion. Over the past 7 years, distal radial access has exploded into all areas of endovascular procedures, from interventional cardiology to vascular surgery and interventional oncology. However, puncture of the distal radial artery has its own nuances and features: a learning curve, the use of ultrasound navigation in the initial stages of mastering the access, limitations in patients with acute conditions (acute coronary syndrome and stroke).

Effect of the "door-to-balloon" time on the results of treatment of patients with ST-segment elevation myocardial infarction, depending on the duration of the pre-hospital delay.

Aim    To analyze the effect of the door-to-balloon time on treatment outcomes in patients with acute ST-segment elevation myocardial infarction (STEMI) depending on the duration of pre-hospital delay.Material ad methods    The study used data of the hospital registry of percutaneous coronary interventions (PCI) in STEMI from 2006 through 2017. The analysis included 1333 patients.

Some Topical Aspects of the "Sports Heart" Problem. Literature Review. Part 2.

Electrocardiography occupies a special place among a significant list of other methods for diagnosing the pathology of the cardiovascular system of athletes. Often its results differ significantly from those in the general population, being a consequence of the adaptation of the heart to economical functioning at rest and super-intensive work in training and competitions. This review focuses on the features of the "athlete's electrocardiogram (ECG).
