Usefulness of triglyceride-glucose index and homeostatic model assessment for predicting coronary microvascular dysfunction.

Background: Coronary microvascular dysfunction (CMD) is a common occurrence in individuals with insulin resistance (IR). Homeostatic model assessment for insulin resistance (HOMA-IR) is a widely used surrogate marker of IR, although recent studies suggest triglyceride-glucose (TyG) index is a superior marker of IR that had a better accuracy to predict type 2 diabetes or cardiovascular outcomes than HOMA-IR.

Objectives: We aimed to assess the accuracy and usefulness of TyG index and HOMA-IR for predicting CMD as assessed with echocardiographic coronary flow reserve (CFR) measurement.

Factors of mortality in patients with cardiac implantable electronic device: 5-year experience.

Objective: The use of cardiac implantable electronic devices has increased in recent years. It has also brought some issues. Among these, the complications of cardiac implantable electronic devices infection and pocket hematoma are difficult to manage.

Role of Malnutrition in Atrial Fibrillation: A Prospective Study including Individuals ≥ 75 Years of Age.

Background: Atrial fibrillation (AF) is the most common rhythm disorder in the elderly. The AF can cause life-threatening thromboembolic complications. Therefore, there is a need to determine the risk factors of AF.

Impaired Renal Vein Flow in Atrial Fibrillation: A Potential Risk for Renal Dysfunction.

BACKGROUND Atrial fibrillation (AF) is one of the most common heart rhythm disorders. Identification and early treatment of AF risk factors can improve mortality and morbidity rates. This study aimed to compare the renal venous stasis index (RVSI) and intra-renal venous flow (IRVF) patterns evaluated by intra-renal Doppler ultrasonography in patients with AF and sinus rhythm (SR).

How Scientific Are We in the Field of Cardiology?

Objective: The current study investigated the contribution of the dissertations produced in the field of cardiology to the scientific literature and the factors affecting the publication process.

Methods: The study included 1049 cardiology dissertations archived in the national thesis center database between January 2010 and December 2017. The titles (English and Turkish), abstracts, and author names of cardiology dissertations were searched in Google Academic, TR Directory, and PubMed Central databases.

Effect of Smokeless Tobacco (Maras Powder) on the Epicardial Fat Thickness and Ventricular Repolarization Parameters.

: Smokeless tobacco (ST) use has recently become an alternative to cigarettes, and it has been concluded that ST is at least as harmful as cigarettes. ST use is thought to play a role in the pathogenesis of arrhythmia by affecting ventricular repolarization. In this study, we aimed to examine the relationships of Maras powder (MP), one of the ST varieties, with epicardial fat thickness and new ventricular repolarization parameters, which have not previously been described.

Dapagliflozin Improves Cardiac Autonomic Function Measures in Type 2 Diabetic Patients with Cardiac Autonomic Neuropathy.

Background: Cardiac autonomic neuropathy is a frequent complication of type 2 diabetes mellitus. Cardiac autonomic neuropathy, in which sympathetic tone predominates over parasympathetic activity, increases both cardiovascular morbidity and mortality and unfortunately has no definitive treatment. Sodium-glucose cotransporter-2 inhibitors have been suggested to reduce sympathetic nervous system activity, based on the results from previous studies.

Association of serum FGF-23, klotho, fetuin-A, osteopontin, osteoprotegerin and hs-CRP levels with coronary artery disease.

Environmental, genetic, oxidative and biochemical factors play an important role in the atherosclerotic process. We investigated the association of serum fibroblast growth factor (FGF-23), klotho, fetuin-A, osteoprotegerin (OPG), osteopontin (OPN) and high-sensitive-CRP (Hs-CRP) markers with coronary artery disease and whether one was superior to others or not. A study group of 52 patients with coronary artery disease (CAD) and a control group of 30 patients with angiographically normal epicardial coronary arteries were included in the study.
