Atrial electromechanical coupling interval and P-wave dispersion in healthy elderly.

Background And Aims: The aim of our study was to investigate the potential effect of natural aging on atrial fibrillation (AF) by means of electrocardiographic P-wave analysis and measurement of the transthoracic echocardiographic electromechanical coupling interval (EMC).

Methods: The study comprised 25 healthy individuals aged ≥65 years (group 1) and 25 control subjects <65 years (group 2). The difference between maximum (Pmax) and minimum (Pmin) P-wave durations on 12-lead electrocardiography were defined as P-wave dispersion (PD).

Heart rate variability in neonates with hypoxic ischemic encephalopathy.

Objective: To evaluate the changes in heart rate variability (HRV) in newborns with hypoxic-ischemic encephalopathy (HIE).

Methods: Twenty-two newborns (14 boys, 8 girls) with moderate or severe HIE and 24 term neonates with similar gestational and postnatal age for control were included in this study. Normalized low and high frequency components of HRV and their ratio were evaluated for 24-h in newborns with HIE and control subjects.

The relationship between serum sex steroid levels and heart rate variability parameters in males and the effect of age.

Objectives: We evaluated the relationships between sex steroid levels and heart rate variability (HRV) parameters.

Study Design: The study included 114 male subjects (mean age 46.6±11.

Differences in autonomic activity in individuals with optimal, normal, and high-normal blood pressure levels.

Objectives: We investigated differences in autonomic activity in normotensive individuals having optimal, normal and high-normal blood pressure (BP) levels according to the guidelines of the European Society of Hypertension and European Society of Cardiology (ESH/ESC).

Study Design: The study included 294 normotensive subjects (135 males, 159 females; age range 16 to 75 years) with similar clinical, morphometric, biochemical, electrocardiographic, and echocardiographic features. The subjects were classified into the following BP groups: group 1 (n=113) with optimal BP (<120/80 mmHg); group 2 (n=104) with normal BP (120-129/80-84 mmHg), and group 3 (n=77) with high-normal BP (130-139/85-89 mmHg).

The difference of heart rate recovery between males with and without erectile dysfunction.

Aim: In this study, we aimed to investigate the relationship between heart rate recovery (HRR) time and Chronotropic Index (CHIND) parameters, which also reflect autonomic function, after exercise stress test (EST) in males with or without erectile dysfunction (ED), and we investigated the relationship between HRR and CHIND and serum steroid hormone levels.

Material And Methods: A total of 135 participants (mean age: 45.0 +/- 11.

Comparison of the differences in circadian autonomic function in hyperlipidemic men with and without erectile dysfunction.

Background: We aimed to investigate differences in circadian autonomic changes in patients suffering from hyperlipidemia with and without erectile dysfunction and compared results to control cases.

Materials And Methods: A total of 77 patients (age range: 24-74, mean age: 45.3 ± 9.

Assessment of the autonomic nervous system is an appropriate biological marker for the well-being in erectile dysfunction.

Aim: To investigate whether the autonomic nervous system (ANS) components are suitable biological markers for representing well-being in patients with erectile dysfunction (ED).

Methods: The present study included 74 male patients who had applied for check-ups in the cardiology outpatient clinic at Kirikkale University (Kirikkale, Turkey) and who had been diagnosed as having hyperlipidemia. Of these patients, 26 had an additional diagnosis of ED and made up the patient group.

Effects of statin treatment on serum sex steroids levels and autonomic and erectile function.

Objectives: To investigate the effect of statin treatment on serum sex steroid levels, heart rate variability, erectile function, and libido in patients with hyperlipidemia.

Methods: A total of 74 patients (mean age 44.7 +/- 7.

A case of Guillain-Barré syndrome following prosthetic valve endocarditis.

Guillain-Barré syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy associated with progressive limb weakness and areflexia. Up to now, a few cases of GBS following infective endocarditis (IE), particularly prosthetic valve endocarditis, have been reported. We present a case of a 63-year-old male patient in whom GBS developed following aortic prosthetic valve endocarditis.

Coronary stent strut fracture after drug-eluting stent implantation: a newly recognized complication.

Stent strut fracture (SSF) after drug-eluting stent (DES) implantation may be an important complication after DES implantation particularly in patients undergoing sirolimus eluting stent implantation. Since SSF is a highly relevant adverse event which can result in in-stent restenosis and thrombosis, we believe that DES with flexible stent platform or biodegradable DES may be needed to prevent this potential catastrophic complication.

Relationship of left ventricular mass to insulin sensitivity and body mass index in healthy individuals.

Objective: The objective of this study was to investigate the contribution of insulin resistance, hyperinsulinaemia and obesity, independently of other major factors, to changes in left ventricular mass a cardiovascular risk indicator, in a healthy population without co-morbid states such as diabetes or hypertension.

Methods And Results: This cross-sectional relational study was perfomed in 153 healthy subjects, comprising 76 men and 77 women with ages ranging from 23 to 67 years. All of them were normotensive and had a normal oral glucose tolerance test, none had cardiovascular disease and none were taking any medication.
