Right ventricular and right atrial free wall deformation predicitive value in transformation of preclinical diastolic disfunction to heart failure with preserved ejection fraction.

Aim      To study echocardiographic parameters of heart chamber strain in patients with left ventricular (LV) preclinical diastolic dysfunction (PDD) for determining predictors of the PDD transition to heart failure with preserved LV ejection fraction (HFpEF).Material and methods  The study included 113 patients (including 69 women) with metabolic syndrome and LV PDD (mean age, 65±7 years). The control group consisted of 40 healthy individuals (mean age, 63.

[Clinical Course and Predictors of Ischemic Mitral Regurgitation in Patients with Myocardial Infarctions of Different Localizations].

Purpose: to assess the clinical course of ischemic mitral regurgitation (IMR) in patients with myocardial infarction of different localizations and reveal its mechanisms and predictors.

Materials And Methods: We enrolled in this study patients with first inferoposterior myocardial infarction (IPMI) (n=77), and anteroseptal MI (ASMI) (n=79) revascularized within 12 hours after symptoms onset, as well as age, sex and weight matched healthy control subjects (n=50). Parameters of mitral structures and mitral annulus areas (MAA), left ventricular (LV) volumes (LVV) and sphericity index (SI), global (G) and segmental (S) longitudinal LV strain (GLS, SLS), papillary muscles (PM) LS (PMLS) and PM systolic dyssynchrony (PMSD) were measured by echocardiography on the 7th and 180th days of follow up.

Data sharing: A new editorial initiative of the International Committee of Medical Journal Editors. Implications for the editors' network.

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship -emphasizing the importance of responsibility and accountability-, have been proposed.
