Prediction of New-Onset Atrial Fibrillation in Transcatheter Aortic Valve Implantation.

Background: This study investigates the association between prolonged total atrial conduction time and the development of new-onset atrial fibrillation (AF) following transcatheter aortic valve implantation (TAVI).

Methods: We enrolled 307 patients who underwent TAVI. Total atrial conduction time was calculated as the time between the onset of the P wave on the electrocardiography and the peak of the a' wave velocity (PA-TDI duration) on tissue Doppler imaging echocardiography.

Evaluation of the relation between subclinical systolic dysfunction defined by four-dimensional speckle-tracking echocardiography and growth differentiation factor-15 levels in patients with acromegaly.

Purpose: In patients with acromegaly, the long-term presence of elevated GH and IGF-1 levels is associated with an unfavorable cardiovascular risk profile. We aimed to assess the relationship of four-dimensional speckle tracking echocardiographic (4DSTE) measurements with growth differentiation factor-15 (GDF-15) levels and the Framingham Cardiovascular Risk Score (FRS) in patients with acromegaly.

Methods: A single-center, cross-sectional study was conducted.

Four‑Dimensional Echocardiographic Evaluation of Cardiac Iron Overload in Patients with Beta-Thalassemia Major.

Cardiac magnetic resonance imaging is the gold standard to detect cardiac iron overload in patients with beta-thalassemia. The aim of this study was to evaluate cardiac iron overload using four-dimensional transthoracic echocardiography in thalassemia patients with and without cardiac involvement detected by T2* value and to compare the two techniques. This cross-sectional and observational study was conducted in 44 patients diagnosed with thalassemia major.

Bone Marrow Origin of Coronary Artery Diseases: The Impact of the Local Renin-Angiotensin System.

The renin-angiotensin system (RAS) has both important systemic circulatory and local effects. The effects of local cardiac RAS on the cardiovascular system have been increasingly researched. In this study, we review the relationship between local bone marrow and local cardiac RAS and their impacts on atherosclerosis.

All- Retinoic Acid-Induced Isolated Myocarditis: A Case Report and Review of the Literature.

All- retinoic acid (ATRA) is the mainstay of treatment in patients with acute promyelocytic leukemia. Despite being effective, it can lead to cardiac complications either as a component of ATRA syndrome or an isolated form denominated as ATRA-induced isolated perimyocarditis. We present a case of this complication and review the literature.

Assessment of Diastolic Function and Thiol-Disulphide Homeostasis in Arsenic-Exposed Workers.

Objectives: Exposure to arsenic is associated with various cardiovascular diseases. The imbalance between antioxidant and oxidant homeostasis plays a crucial role in the cardiovascular effects of arsenic. The aim of this study was to investigate the effect of arsenic exposure on diastolic function by measuring thiol and disulphide in arsenic-exposed workers.

Four-Dimensional Echocardiographic Evaluation of Left Ventricular Systolic Functions in Patients with Chronic Myeloid Leukaemia Receiving Tyrosine Kinase Inhibitors.

Tyrosine kinase inhibitors (TKIs) are established treatment for haematological malignancies. However, cardiac adverse effects, including the reduction in left ventricular ejection fraction and symptomatic heart failure remain clinical problems. The purpose of this study was to evaluate the left ventricular systolic functions in patients with chronic myeloid leukaemia receiving TKIs.

Serum endocan level and diastolic functions in the case of lead exposure.

Background/aim: Lead can cause morphological and functional changes in heart, and inflammation and endothelial dysfunction in vasculature. Endocan, as a novel indicator of endothelial dysfunction, has been used for cardiovascular diseases. This study investigated the relationship between lead exposure, endocan levels, and diastolic functions.

Evaluation of Erectile Dysfunction and Left Ventricular Diastolic Parameters in Lead Exposed Workers.

Background: Lead exposure causes a wide range of vascular diseases through oxidative stress, sympathetic hyperactivity and impairment in nitric oxide bioavailability. In this study, the association between the effects of lead exposure on left ventricular diastolic indices and erectile function were assessed.

Methods: A total of 94 lead-exposed workers without known cardiovascular diseases or risk factors and 30 healthy subjects were enrolled.

Evaluation of the ambulatory arterial stiffness index in lead-exposed workers.

Objective: Lead exposure has been associated with various cardiovascular disorders. It may also cause increased inflammation and fibrosis in the arterial system resulting in an increase in arterial stiffness. In this study, the ambulatory arterial stiffness index (AASI), which is a technique that measures arterial stiffness, was evaluated in occupationally lead-exposed workers.

Assessment of heart rate response to exercise and recovery during treadmill testing in arsenic-exposed workers.

Background: Arsenic exposure is associated with various cardiovascular diseases. The aim of the present study was to assess cardiac autonomic function via heart rate response to exercise and recovery period of treadmill testing in arsenic-exposed workers.

Methods: Sixty-five (65) occupationally arsenic-exposed workers and 35 healthy controls were enrolled.

Exercise heart rate recovery assessment of the cardiac autonomic nervous system in workers occupationally exposed to lead.

Objective: The aim of the present study was to assess cardiac autonomic function via indices of exercise heart rate recovery (HRR) in workers occupationally exposed to lead.

Methods: A total of 98 lead-exposed workers and 98 healthy controls were enrolled. All underwent exercise testing and transthoracic echocardiography.

Assessment of cardiac autonomic functions by heart rate recovery indices in patients with myocardial bridge.

Background: Heart rate (HR) recovery (HRR) reflects autonomic activity and predicts cardiovascular events. The aim of this study was to assess HRR in patients with myocardial bridge (MB).

Methods: Medical recordings of 93 patients with MB and appropriate age, compared to 78 sex-matched healthy subjects were analyzed.
