Empagliflozin and Dapagliflozin Therapies Favorably Alter QRS-T Angle and Cardiac Repolarization Parameters in Patients with Heart Failure.

Recent randomized clinical trials demonstrated that treatment with sodium-glucose cotransporter-2 inhibitors (SGLT2is) reduces the risk of cardiac mortality due to sudden cardiac death and progressive pump failure in patients with heart failure (HF). Mechanisms underlying the potential anti-arrhythmic effects of SGLT2is are not well understood. We aimed to examine the effect of SGLT2i treatment on the frontal-plane QRS-T (f[QRS-T]) angle, a novel marker of myocardial repolarization and an independent predictor of adverse cardiac outcomes.

Clozapine-Induced Myocarditis in a Young Man with Refractory Schizophrenia: Case Report of a Rare Adverse Event and Review of the Literature.

BACKGROUND Myocarditis is cardiac muscle inflammation caused by infectious or noninfectious agents. Rarely, clozapine, an atypical antipsychotic drug used to treat resistant schizophrenia, has been reported to cause myocarditis, as we report in this case. CASE REPORT A 29-year-old man, who was known to have schizophrenia and was on olanzapine therapy, presented in our Emergency Department with active psychosis, and was subsequently admitted to the psychiatric ward for refractory schizophrenia.

CRP Albumin Ratio May Predict No Reflow in Patients Undergoing Percutaneous Coronary Intervention for Saphenous Vein Graft Stenosis.

Many hypotheses have been proposed to explain no-reflow (NR). Some of these hypotheses, state that NR may be caused by damage to the vascular endothelium and an inflammatory process. In a recent study that did not include patients with coronary artery bypass graft (CABG), the ratio of C-reactive protein (CRP) to albumin (CAR) was found to be associated with NR.

Monocyte-to-HDL-cholesterol ratio is associated with Ascending Aorta Dilatation in Patients with Bicuspid Aortic Valve.

Background: The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the patients with bicuspid aortic valve.

Cardiac involvement in MRI in young population after COVID-19: A single tertiary center experience.

Background: Coronavirus 2019 (COVID-19) causes morbidity and mortality in an increasing number of people worldwide. Although it mainly affects the respiratory system, it influences all organs, including the heart. It is associated with a broad spectrum of widespread cardiovascular problems ranging from mild myocardial injury to fulminant myocarditis.

Effect of chelation therapy on arrhythmogenic and basal ECG parameters of lead exposed workers.

Lead exposure has etiological role on cardiovascular system diseases as hypertension, atherosclerosis, stroke, and arrhythmic events. In this study, we aimed to compare the basal and arrhythmogenic ECG parameters of lead exposed workers before and after chelation therapy and to evaluate the effect of acute change of blood lead levels on ECG. Fourty consecutive occupationally lead exposed workers were enrolled, demographic, blood, echocardiographic, and electrocardiographic data's were analyzed before and after chelation therapy.

Frontal plane QRS-T angle may be a predictor for post-coronary artery bypass graft surgery atrial fibrillation.

Background: New-onset postoperative atrial fibrillation (POAF) is the most common arrhythmia following coronary artery bypass graft surgery (CABG) and is associated with prolonged hospitalization, stroke, and mortality. The frontal plane QRS-T [f(QRS-T)] angle, which is defined as the angle between the directions of ventricular depolarization (QRS-axis) and repolarization (T-axis), is a novel marker of ventricular repolarization heterogeneity. The f(QRS-T) angle is associated with adverse cardiac outcomes.

A new risk model for the evaluation of the thromboembolic milieu in patients with atrial fibrillation: the PALSE score.

Background: The evaluation of thromboembolic risk is the cornerstone of atrial fibrillation (AF) management. Thromboembolic risk is associated with the presence of left atrial (LA) thrombus and spontaneous echo contrast (SEC), namely the thromboembolic milieu.

Aims: We aimed to assess the predictors of the thromboembolic milieu in terms of LA thrombus and/ or SEC in patients with paroxysmal AF undergoing electrical cardioversion or catheter ablation, and to develop an effective risk model for detecting the thromboembolic milieu.

Evaluation of frontal plane QRS-T angle in patients with slow coronary flow.

. Frontal plane QRS-T angle is a novel marker of myocardial repolarization, and an increased frontal plane QRS-T angle is associated with adverse cardiac outcomes. Slow coronary flow may cause fatal cardiac arrhythmias by causing electrical abnormalities and altering ventricular repolarization.

Nesfatin-1: A novel regulatory peptide associated with acute myocardial infarction and Mediterranean diet.

We evaluated the relationship between nesfatin-1 and acute myocardial infarction (AMI) and Mediterranean diet scores. 67 patients with AMI and 33 patients with normal coronary arteries (control group) were included in the study. The patients with AMI were divided into 2 groups based on low (<32) (n = 33) and high values of the synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) scores (≥34) (n = 35).

The association of estimated whole blood viscosity with hemodynamic parameters and prognosis in patients with heart failure.

Aim: We aimed to investigate the association of estimated whole blood viscosity (WBV) with hemodynamic parameters and prognosis in patients with heart failure with reduced ejection fraction.

Materials & Methods: Total of 542 patients were included and followed-up for median 13 months.

Results: The WBV parameters had negative relationship with right atrium pressure and positive correlation with cardiac index.

The Relationship between Nesfatin-1 Levels and SYNTAX Score in Patients with Non-ST Segment Elevation Myocardial Infarction.

Objective: Nesfatin-1 is a novel anorectic neuropeptide with potent metabolic regulatory effects. It regulates blood pressure, heart rate, cardiomyocyte metabolism and permeability. SYNTAX score, which is an angiographic scoring system, defines the grade and complexity of coronary artery disease (CAD).
