Objective: Atrial high-rate episodes (AHRE) are atrial tachyarrhythmia episodes detected by implanted cardiac devices, characterised by an atrial rate exceeding 180-190 beats per minute. Recent studies have linked AHRE to the development of atrial fibrillation (AF) and increased stroke risk, especially when episodes last longer than 5-6 min. This study aimed to evaluate the relationship between predictive factors and the occurrence of AHRE in heart failure with reduced ejection fraction (HFrEF) patients with cardiac implantable electronic devices (CIEDs).

The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes.

Purpose: Long-term administration of glucocorticoids (GCs) increases myocardial oxidative stress. 4-Hydroxynonenal (4-HNE) protein adducts, a marker of oxidative damage, have been associated with several cardiovascular diseases, including atherosclerosis, cardiac hypertrophy, cardiomyopathy, and ischemia-reperfusion injury. Exercise training has been shown to have a protective effect on the heart by lowering the level of oxidative stress in cardiomyocytes.

Purpose: Glucocorticoids, which are widely prescribed around the world, cause cardiac remodeling in long-term treatment by triggering insulin resistance and increasing blood pressure. However, its role in cardiac remodeling remains unclear. Galectin-3 (gal-3) is a member of a beta-galactoside-binding animal lectins, upregulated as a result of insulin resistance and in the pressure-overloaded myocardium and regulate cardiac remodeling.

Objective: This study aimed to assess the usefulness of serial NGAL measurements with a point-of-care assay in patients with left ventricular systolic dysfunction (LVSD) for earlier detection of contrast-induced nephropathy (CIN).
Materials And Methods: A total of 84 patients with LVSD patients referred for coronary angiography were consecutively enrolled in the study.
Background: Rheumatic mitral valve disease (RMVD) is the most common presentation of rheumatic heart disease (RHD). Inflammation and fibrosis processes also play significant roles in its pathogenesis. Recent studies showed that thiols and thiol-disulfide are promising novel oxidative stress markers.

Although they have positive effects on the treatment of various disease states; long-term administration is associated with high blood pressure, insulin resistance, and susceptibility to type 2 diabetes. The heart attempts to cope with increased blood pressure and a decrease in glucose utilization by developing pathological cardiac remodeling.

A total of consecutive 530 patients who had been evaluated by ambulatory blood pressure monitoring were included. WBV was estimated by using hematocrit and plasma total protein levels for both WBV in low shear rate (0.

However, concerns exist over treating patients who have undergone previous mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a case in which a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement was successfully treated with TAVI using a Portico valve, which is under-researched

Recent studies have reported the thiol-disulfide ratio as a novel oxidative stress marker. Therefore, we investigated the role of thiol levels in predicting CIN in patients with ST-segment elevation myocardial infarction (STEMI) who had undergone primary percutaneous coronary intervention (PCI).

In patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. Left atrial appendage (LAA) closure is an emerging option in AF patients who are not eligible for oral anticoagulation therapy because of contraindications or high bleeding risk.

Acute cardiogenic pulmonary edema (ACPE) constitutes approximately 10-20% of acute heart failure syndromes, and it is the most dramatic symptom of left heart failure. Platelet to lymphocyte ratio (PLR) is a relatively novel inflammatory marker that can be utilized for prognosis in various disease processes.

The aim of this study was to assess ECG QRS axis changes and other ECG parameters after HD in patients with end-stage renal disease (ESRD).
Methods: A total of 46 patients (65% male, mean age 52±15 years) with a sinus rhythm and without cardiovascular disease who were undergoing chronic HD treatment were included to the study.
Objective: Exaggerated blood pressure response to exercise is a risk factor for the development of future hypertension. In this study, we aimed to investigate the association between homocysteine, epicardial fat thickness, nonalcoholic hepatic steatosis, and exaggerated blood pressure response to exercise.
Participants And Methods: We included 44 normotensive and 40 patients with exaggerated blood pressure response to exercise who have normal resting blood pressure and without a previous diagnosis of hypertension.
Objectives: Elucidation of the underlying mechanisms of angiogenesis and arteriogenesis in coronary collateral formation is necessary for new therapies. Pleiotrophin is a secreted multifunctional cytokine and associated with the formation of functional cardiovascular neovascularization in a series of experimental animal models. We aimed to evaluate the serum levels of pleiotrophin in patients with chronic total coronary artery occlusion and poor or good collateral development.

The factor Xa inhibitor rivaroxaban reduced mortality and ischaemic events when added to DAPT, but caused increased bleeding. The safety of a dual pathway antithrombotic therapy approach combining low-dose rivaroxaban (in place of aspirin) with a P2Y12 inhibitor has not been assesssed in acute coronary syndromes.

In this study, we aimed to evaluate the changes in the hematological parameters before and after exercise stress test in relation with the presence of CAD.
Methods: A total of 113 patients with chest pain who underwent treadmill exercise testing and coronary angiography were included in this study.
Background: Recently fragmented QRS (fQRS) on electrocardiography (ECG) has been introduced as a predictor of myocardial scarring and myocardial ischemia in coronary artery disease (CAD).
Objective: The aim of this study was to investigate the relationship between fQRS and fractional flow reserve (FFR) results in patients with the intermediate degree of coronary artery stenosis.
Methods: A total of 301 consecutive patients who underwent coronary angiography (CAG) and FFR measurement for intermediate coronary artery stenosis were included in the study.
Background: The current study aimed to evaluate the influence of regular annual influenza vaccinations on cardiovascular (CV) death and heart failure-related hospitalizations (HFrH) in stable outpatients with heart failure with reduced ejection fraction.
Methods: The Turkish research team-HF (TREAT-HF) is a network undertaking multicenter, observational cohort studies in HF. This study is a subgroup analysis of TREAT-HF outpatient cohorts who completed a questionnaire on influenza vaccination status and for whom follow-up data were available.
Objective: Aortic stiffness and chronic kidney disease share common risk factors. Increased aortic stiffness is a predictor of lower estimated glomerular filtration rate (eGFR) at lower levels of renal functions. We aimed to investigate the association between invasively measured central aortic pulsatility (AP) as an indicator of aortic stiffness and eGFR in a population with coronary artery disease and without overt renal disease.
