PURPOSE Polycystic ovary syndrome (PCOS) is frequently accompanied by the presence of cardiovascular risk factors. The aim of this study was to determine and compare the echocardiographic profiles of patients with PCOS with those of healthy subjects by using conventional echocardiographic methods and tissue Doppler imaging. METHODS The study population(More)
BACKGROUND Experimental data demonstrated that inflammatory mediators, such as pro-inflammatory and anti-inflammatory cytokines and their receptors might have important role in the development and the progression of heart failure (HF). Statins were shown to downregulate inflammatory cytokines in HF. Interleukin (IL)-10 is one of the most important(More)
PURPOSE The effects of epilepsy and seizures on cardiac functions have been documented, and this association has drawn attention in recent years. The aim of this study was to investigate left ventricle (LV) diastolic function by tissue Doppler imaging (TDI) in patients with newly diagnosed and untreated primary generalized epilepsy (PGE). METHOD Thirty(More)
The value of echocardiography, especially tissue Doppler imaging (TDI), in the assessment of risk of postoperative atrial fibrillation (AF) after coronary artery bypass grafting (CABG) is not clear. One hundred two consecutive patients (80 men; mean age 61 +/- 10 years) who underwent elective isolated CABG were included in the study. All patients underwent(More)
PURPOSE Polycystic ovary syndrome (PCOS) is frequently accompanied by the presence of cardiovascular risk factors. It has also been recognized that there is a significant relationship between the autonomic nervous system and adverse cardiac events. Heart rate recovery (HRR) after exercise is a marker of parasympathetic activity and attenuation of this(More)
OBJECTIVE In this study, we aimed to demonstrate whether the presence of fragmented QRS (fQRS) is associated with the frequency of premature ventricular contractions (PVCs). METHODS We retrospectively analyzed 282 cases by 24-hour Holter monitorings (HMs) between August 2012 and February 2013. Firstly, the patients were divided into 2 groups with respect(More)
OBJECTIVES The aim of our study was to evaluate the influence of lung resection on cardiac functions by using tissue Doppler echocardiography. STUDY DESIGN Nineteen consecutive patients (15 males, 4 females; mean age 55+/-8 years) undergoing major lung surgery (16 lobectomy, 3 pneumonectomy) were evaluated in a prospective design. Malignant lung cancer(More)
