Relationship between ECG-derived T-wave amplitude and T/R ratio and Syntax score in patients with acute non-st segment elevation myocardial infarction.

Objectives And Background: Our objective was to determine the diagnostic significance of a low T-wave amplitude (TWA) and T/R ratio, defined as the amplitude ratio between the T waves and the R waves, in patients with acute non-ST elevation myocardial infarction (ANSTEMI). Syntax score (SS) shows the extension of coronary artery disease. Previously, low TWA and T/R ratios were demonstrated to be inversely proportional to the risk of sudden cardiac arrest in different cardiac disease conditions.

Serum omentin-1 levels in hypertensive patients.

Hypertension (HT) is a disease that can cause death due to multiple target organ damage and eventually related vascular system damage. High blood pressure is known increased inflammatory activity and to cause endothelial dysfunction has been showed in HT patients. Omentin-1 is a glucoprotein of the adiponectin family released from visceral adipose tissue, endothelial cells, and visceral fat stromal-vascular cells.

Nesfatin-1 Levels Predict Angiographic No-Reflow in Patients with ST-Segment Elevation Myocardial Infarction.

Background: Nesfatin-1 is a novel peptide possessing pleiotropic metabolic effects. No-reflow phenomenon (NR) is a poor prognostic indicator occurring in around 30% of all patients undergoing primary percutaneous coronary interventions (pPCI). Inflammation and complexity of coronary artery disease (CAD) play pivotal roles in the pathogenesis of NR.

Wet Cupping Therapy Improves the Parameters of Ventricular Repolarization.

Background: Cupping therapy (CT) is an ancient medical treatment since antiquity and is used for the treatment of such various disease states as contagious diseases, chronic or acute inflammatory disease, and autoimmune disorders. Ventricular repolarization is represented by QT and corrected-QT (QTc) intervals from surface electrocardiography.

Objectives: As novel repolarization parameters, Tpeak-toTend (Tp-Te) interval, and Tp-Te/QT and Tp-Te/QTc ratios are suggested to correlate better with ventricular arrhythmia risk in various clinical conditions than sole QT and QTc intervals.

Effect of habitual cigarette smoking on the index of cardiac electrophysiological balance in apparently healthy individuals.

Background And Aim: Chronic cigarette smoking has been suggested to portend risk for cardiac arrhythmia generation. Index of cardiac electrophysiological balance (iCEB) is a relatively new ECG parameter indicating balance between ventricular depolarization and repolarization, thereby providing more insight concerning ventricular arrhythmogenesis (VA) than other classical ECG parameters such as QT and corrected QT (QTc) intervals. The present study aimed to assess the status of iCEB in healthy habitual smokers.

Relationship of growth differentiation factor-15 with aortic stiffness in essential hypertension.

Aim: We aimed to assess the relationship between echocardiographic parameters of aortic elasticity, namely aortic strain, aortic distensibility and aortic β-index, and serum growth differentiation factor (GDF)-15 in patients with newly diagnosed essential hypertension (HT).

Methods: Grade-1 HT patients (n = 50), grade-2 HT (n = 70) patients and 35 healthy controls were included.

Results: GDF-15 was greater in grade-2 HT group compared with the other groups.

Usefulness of Tp-Te interval and Tp-Te/QT ratio in the prediction of ventricular arrhythmias and mortality in acute STEMI patients undergoing fibrinolytic therapy.

Background And Aim: Acute ST-elevation myocardial infarction (STEMI) is associated with fatal and non-fatal ventricular arrhythmic events (VAE). Although primary percutaneous intervention (PCI) is first-line treatment in STEMI, fibrinolytic therapy (FT) is still widely used in many countries. Tp-Te interval; Tp-Te/QT ratio and QT dispersion (QTd) are novel markers of ventricular repolarization (VR) and associate with VAE and mortality.

Usefulness of white blood cell count to mean platelet volume ratio in the prediction of SYNTAX score in patients with non-ST elevation myocardial infarction.

Objective: White blood cell (WBC) count to mean platelet volume (MPV) ratio (WMR) is associated with major adverse cardiovascular events in patients with non-ST elevation acute coronary syndrome (NSTEMI). We aimed to compare WMR between NSTEMI patients and matched-controls and to evaluate its predictive value on SYNTAX score.

Methods: Total 175 patients with NSTEMI and 160 age and co-morbidity matched subjects were recruited in our study.

Association between Growth Differentiation Factor 15 and Non-Dipping Circadian Pattern in Patients with Newly Diagnosed Essential Hypertension.

Objective: Non-dipper hypertension (HT) confers greater risk compared with dipper HT. Growth differentiation factor 15 (GDF-15) recently emerged as a novel and independent marker of cardiovascular disease, both in diagnostic and prognostic scopes. Our aim was to evaluate the relationship of circadian blood pressure (BP) pattern with serum GDF-15 level in newly diagnosed HT patients without left ventricular hypertrophy.
