Electrocardiography clues in assessment of patients with premature ventricular contractions.

A relationship between PLR and severity of carotid stenosis has been shown. The aim of our study was to investigate the relationship between PLR and all cause mortality in patients with carotid arterial disease.

The additive effects of OSA and nondipping status on early markers of subclinical atherosclerosis in normotensive patients: a cross-sectional study.

The additive effect of hypertension on carotid atherosclerosis in patients with obstructive sleep apnea (OSA) is well-established; however, the effect of the nondipping pattern has not yet been evaluated. In this study, we aim to assess the effect of the nondipping pattern on carotid atherosclerosis, which is quantified as carotid intima-media thickness (CIMT), and on the high-risk carotid profile in normotensive patients with OSA. We included 189 patients with OSA in this cross-sectional study.

[Increased myocardial energy expenditure in cardiac syndrome X: More work, more pain].

Objective: The aim of this study was to assess the myocardial energy expenditure (MEE) in patients with cardiac syndrome X (CSX) and to examine its association with exercise electrocardiogram (ECG) parameters.

Methods: A total of 99 patients who underwent coronary angiography and who were diagnosed as having normal coronary arteries were included. The patients were divided into 2 groups based on symptoms and exercise ECG parameters: 56 CSX patients and 43 control patients with a negative stress test.

Platelet distribution width and plateletcrit: novel biomarkers of ST elevation myocardial infarction in young patients.

Background: Platelets play a central role in myocardial infarction, and platelet activity can be evaluated with platelet indices, including platelet distribution width (PDW) and plateletcrit (PCT). These indices have been demonstrated as markers of prothrombotic state in cardiovascular diseases.

Aim: Therefore, we aimed to investigate, the usefulness of these biomarkers in ST-elevation myocardial infarction (STEMI) in young patients.

Association between RDW and stent thrombosis in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Stent thrombosis is a rare but potentially fatal complication of percutaneous coronary interventions (PCIs). In recent years, the predictive and prognostic value of the red cell distribution width (RDW) as an indicator of inflammation has been shown in many cardiovascular diseases. Aim of this study was to examine the predictive value of RDW for stent thrombosis in patients who underwent successful stent implantation for ST-elevation myocardial infarction (STEMI).

Background: The interaction of platelets with leukocytes is a well-known process both in progression and prognosis of acute pulmonary embolism (PE). Recently, platelet to lymphocyte ratio (PLR) is emerged as an indirect inflammatory indicator which was shown to be associated with adverse cardiovascular events in various clinical conditions, including acute PE.
