[Modern methods of assessment of physiological significance of coronary lesions: A review].

The article describes the main methods of assessment of physiological significance of coronary artery stenoses, their use in clinical practice and future perspectives. New diagnostic methods that are currently under research are discussed.

[Computed tomography in cardiology: history and perspectives].

The review article highlights the main stages of the formation of computed tomography (CT) as a key method used in modern cardiology. The progress of CT scanners is directly related to the increase in the number of detectors, and thus, with an increase in the number of simultaneously collected projections. Modern developments and future technologies in the field of further development of the technique, including CT angiography and other new methods for assessing coronary blood flow, are discussed.

[Relationship between the pain severity, use of non-steroidal anti-inflammatory drugs and blood pressure in elective large joint arthroplasty of the lower extremities].

Aim: To evaluate the changes in blood pressure (BP), the severity of pain syndrome and non-steroidal anti-inflammatory drugs (NSAIDs) use patterns in patients hospitalized for elective arthroplasty of large joints of the lower extremities during the postoperative period.

Materials And Methods: This study included 374 patients. In all patients, medical history, antihypertensive therapy and history of NSAIDs usage were collected, BP was measured, and the severity of pain was assessed via a 10-point scale before surgery, as well as 1 and 3 months after arthroplasty.
