Right Ventricular Function in Surgical Treatment of Left Heart.

Aim    The aim of this study was to evaluate right ventricular (RV) function during left chamber surgery.Material and methods    This was a single-site prospective cohort study. The study included 197 patients with valvular pathology of heart left chambers.

Treatment Strategies for Chronic Coronary Heart Disease with Left Ventricular Systolic Dysfunction or Preserved Ejection Fraction-A Systematic Review and Meta-Analysis.

Unlabelled: In this meta-analysis, we examine the advantages of invasive strategies for patients diagnosed with chronic coronary heart disease (CHD) and preserved left ventricular (LV) function, as well as those with significant LV systolic dysfunction (LV ejection fraction (EF) < 45%).

Material And Methods: We conducted a systematic search to identify all randomized trials directly comparing invasive strategies with optimal medical therapy (OMT) in patients diagnosed with chronic CHD. Data from these trials were pooled using a random-effects meta-analysis.

[The application of statistical programs and methods of data mathematical processing in obstetrics and gynecology].

In recent decades, evidence-based medicine acquired special importance in medicine. Therefore, proper presentation of data obtained in scientific research is extremely important. The statistical data processing, being an integral part of this process, often causes difficulties for researchers and its incorrect application results in distortion of results obtained.

Advantages of Multiposition Scanning in Echocardiographic Assessment of the Severity of Discordant Aortic Stenosis.

Aim Of The Study: The aim of this study was to perform a comparative analysis of severity of discordant aortic stenosis (AS) assessment using multiposition scanning and the standard apical window.

Materials And Methods: All patients ( = 104) underwent preoperative transthoracic echocardiography (TTE) and were ranked according to the degree of AS severity. The reproducibility feasibility of the right parasternal window (RPW) was 75.

Worldwide Prevalence of Alcohol Use in Non-Fatally Injured Motor Vehicle Drivers: A Systematic Review and Meta-Analysis.

Drunk driving is an important risk factor significantly contributing to traffic accidents and their associated lethality. This meta-analysis of observational studies aims to provide the estimates of drunk driving prevalence in non-lethally injured motor vehicle drivers in relation to the world region, blood alcohol concentration (BAC), and quality of the primary study. A systematic search for observational studies that examined the prevalence of drunk driving in injured drivers was performed, and 17 studies comprising 232,198 drivers were included in the pooled analysis.
