Exercise-induced ventricular ectopy (EIVE) has clinical and prognostic significance. But the mechanism underlying EIVE-related mortality still remains unclear. This study aims to assess blood pressure alteration in patients with EIVE and to identify the potential causes of increased mortality in this patient group.

This study aimed to investigate the relationship between the presence of DR and carotid intima-media thickness (CIMT), which is an indicator of early atherosclerosis in patients with type 2 DM.
Methods: Thirty DM patients with retinopathy (DR group), 28 DM patients without retinopathy (non-DR group), and 27 healthy controls (control group) were included in the study.
Objective: To measure the serum erythropoietin (EPO) level in patients with saphenous vein grafts (SVGs) and to compare the EPO level in those with and without SVG disease.
Subjects And Methods: The study included 85 consecutive patients with a history of coronary artery bypass graft surgery that underwent elective coronary angiography. Patients with >30% stenosis (diseased grafts) in at least one saphenous graft were included in group 1 (diseased group: n = 40), and group 2 (nondiseased group: n = 45) consisted of patients without diseased SVGs.
Objectives: The present report describes patients with acute ST-elevation myocardial infarction who had at least two lesions in the culprit vessel (CV) during primary percutaneous coronary intervention (PCI). Here, we aimed to examine two different strategies, namely, PCI of only culprit lesion (CL) versus PCI of all lesions in the CV in the setting of acute ST-elevation myocardial infarction.
Patients And Methods: Patients who underwent primary PCI were examined for the presence of an additional lesion in the infarct-related artery and divided into two groups according to the PCI strategy: CV versus CL groups.
Objective: The objective of this study was to evaluate right ventricular systolic and diastolic functions with the use of conventional and tissue Doppler echocardiography in patients with slow coronary flow (SCF).
Methods And Results: Patients who were detected to have SCF but otherwise normal epicardial coronary arteries between October 2010 and July 2011 were included in our study. The control group was selected from the patients with normal coronary arteries but no SCF.
Objective: Cardiac resynchronization therapy (CRT) improves heart rate variability (HRV) and heart rate turbulence (HRT) parameters. Herein, our aim was to compare these parameters with intracardiac-cardioverter defibrillator (ICD) patients with similar functional status to detect possible additional benefits of CRT on autonomic functions.
Methods: Patients who had systolic HF (NYHA class II and III) with an ejection fraction <35% were enrolled in this observational, cross-sectional study.
Objectives: Monocytes and mature macrophages play significant roles after myocardial infarction. Here, our aim is to investigate the monocyte heterogeneity in acute ST elevation myocardial infarction (STEMI) and non-STEMI separately and determine any possible relationships between monocyte heterogeneity and coronary angiographic characteristics.
Methods: Thirty STEMI, 30 non-STEMI, and 25 stable angina pectoris patients were enrolled.
Objective: To investigate the cross-sectional association between serum adipocyte fatty acid-binding protein (A-FABP) level and diagnosis or severity of obstructive sleep apnea syndrome (OSAS) and some echocardiographic indices related with cardiac dysfunction.
Methods: In this study, plasma A-FABP and high-sensitivity C-reactive protein concentrations were measured, and echocardiography was performed in subjects without any cardiac or pulmonary disease who were referred for evaluation of OSAS. According to the apnea-hypopnea index (AHI), subjects were classified into 3 groups: control group (AHI <5; n = 33), mild to moderate OSAS (30 > AHI ≥ 5; n = 30), and severe OSAS (AHI ≥ 30; n = 31).
Background And Purpose: Coronary collateral circulation (CCC) has been demonstrated to be impaired in patients with type 2 diabetes mellitus which is characterized by insulin resistance. In this study, our purpose was to find out a possible relationship between CCC and non-alcoholic fatty liver disease (NAFLD), which is also characterized by insulin resistance, in non-diabetic patients with severe coronary artery disease.
Methods: One hundred and fifty-one consecutive non-diabetic patients with stable angina pectoris who were found to have >95% stenosis of at least one major coronary artery were enrolled.
Triptans are an established treatment for acute migraine attacks. By activating 5HT1B/1D receptors they lead to vasoconstriction of the cerebral blood vessels which are dilated during migraine attacks. Moreover, they reduce secretion of vasoactive peptides and conduction of pain stimuli over the cerebral cortex.

Methods: In the present retrospective study, 759 patients with normal coronary arteries who underwent coronary angiography between January 2010 and July 2011 were enrolled. The angiograms of eligible patients were reviewed again for thrombolysis in myocardial infarction (TIMI) frame counts.
Objectives: An increased circulating monocyte count has been found to be related to good collateral development in patients with stable coronary artery disease. Our aim in this study was to determine any possible relationship between the levels of circulating monocyte subsets and coronary collateral development.
Methods: Patients who had greater than 95% stenosis of at least one major coronary artery in their first coronary angiogram were included consecutively in this study.
