Negativity of the electromechanical window: relation to frequent premature ventricular complexes.

Objective: The electromechanical window (EMW) was investigated as a new predictor of arrhythmia in the presence of long QT. However, the use of EMW to predict idiopathic frequent ventricular premature complexes (PVCs) in those with normal QT intervals has not been clarified.

Patients And Methods: This single-center study included consecutive patients who presented to the Cardiology Clinic with palpitations and were found to have idiopathic PVC on 24-hour Holter monitoring.

Endotrophin and matrix metalloproteinase-2 levels in bicuspid aortic valve and hypertension associated aortopathy and their relationship with strain parameters of the ascending aorta.

Objective: Bicuspid aortic valve (BAV) is the most common congenital heart defect. Ascending aorta dilatation is related to BAV- and hypertension (HTN)-associated aortopathy. The aim of this study was to investigate aortic elasticity, as well as aortic deformation of the ascending aorta, using strain imaging, and to evaluate the possible relationship of biomarkers, such as endotrophin and matrix metalloproteinase-2 (MMP-2), with ascending aorta dilatation in patients with BAV- or HTN-associated aortopathy.

Subclinical myocardial assessment after BNT162b2 messenger RNA COVID-19 vaccination in adolescents with chronic heart disease: a speckle-tracking echocardiography study.

Purpose: Case reports of the development of perimyocarditis in adolescents and young adults after BNT162b2 messenger RNA (mRNA) COVID-19 vaccination have raised concerns about the cardiac side effects of the vaccine. The aim of the study was to evaluate clinical follow-up and subclinical myocardial function after mRNA COVID-19 vaccine in adolescents with chronic heart disease.

Methods: Forty-one adolescents aged 12-18 who were followed up at paediatric cardiology clinic between December 2021 and May 2022, and who had received two doses of the Pfizer-BioNTech COVID-19 mRNA vaccine were included in the study.

Association between Multiplate-measured aspirin resistance and vitamin D deficiency in stable coronary artery disease.

Introduction: Insufficient inhibition of platelets in patients with atherosclerosis despite antiplatelet therapy leads to important clinical consequences. The present study evaluated the role of vitamin D (VD) deficiency in aspirin resistance (AR) in patients with stable coronary artery disease (CAD) treated with aspirin.

Material And Methods: This study included 70 patients with stable CAD who had been using 100 mg aspirin for at least seven days.

The relation of echo-derived lateral MAPSE to left heart functions and biochemical markers in patients with preserved ejection fraction: Short-term prognostic implications.

Objective: Mitral annular plane systolic excursion (MAPSE) is a simple way to evaluate-left ventricle (LV) function. Our aim was to explain the relationship of MAPSE with LV function and biochemical markers in patients with preserved ejection fraction (EF), and to determine whether it has an effect on prognosis in echocardiography (echo) practice.

Methods: Consecutive patients referred to the echo laboratory between November 2020 and March 2021 were included in the study.

Impairment of right ventricular longitudinal strain associated with severity of pneumonia in patients recovered from COVID-19.

Myocardial injury caused by COVID-19 was reported in hospitalized patients previously. But the information about cardiac consequences of COVID-19 after recovery is limited. The aim of the study was comprehensive echocardiography assessment of right ventricular (RV) in patients recovered from COVID-19.

Evaluation the relationship of left ventricular global longitudinal strain and laboratory parameters in discharged patients with COVID-19: a follow-up study.

Background: The novel coronavirus infection (COVID-19) disease has spread rapidly and posed a great threat to global public health. The laboratory parameters and clinical outcomes of the disease in discharged patients remain unknown. In this study, we aimed to investigate the laboratory and echocardiographic findings of patients with COVID-19 after discharge and the relation between left ventricular global longitudinal strain (LVGLS) and inflammatory parameters in discharged patients.
