Can Tei Index Predict High Syntax Score in Patients with Chronic Coronary Syndrome and Normal Left Ventricular Systolic Function?

Objective: Some patients who had chronic coronary syndrome (CCS) and were recognized as low risk, however, developed cardiovascular events, whereas others who were categorized as high risk did not develop any cardiovascular events. Invasive coronary angiography is the gold standard tool for the assessment of coronary artery disease (CAD) severity. The SYNTAX score (SS) was recently recognized as an invasive angiographic-guided scoring system used in risk stratification of patients who have more than one-vessel CAD and undergoing revascularization with percutaneous cardiovascular intervention.

Outcome of manual thrombus aspiration for patients undergoing primary PCI for acute STEMI showing large thrombus burden.

Background: Routine thrombus aspiration during primary PCI does not improve clinical outcomes. Although recent guidelines for management of patient presented by ST-elevation myocardial infarction treated by primary PCI does not recommend routine use of thrombus aspiration and ranking it as class III recommendation. However, there is remaining uncertainty about rule of TA in group of patients presented by STEMI and their initial coronary angiogram shows large thrombus burden as there is a logical rationale for greater benefit, and still, there are no clear guidelines for management of this group of patients; the aim of this study is to evaluate the in-hospital and short-term outcome of using manual thrombus aspiration in STEMI patients undergoing primary PCI and showing large thrombus burden.

Left atrial deformation analysis as a predictor of severity of coronary artery disease.

Background: Two-dimensional (2D) speckle-tracking strain imaging is a novel method for assessment of regional myocardial deformation that uses tracking of acoustic speckles or kernels rather than Doppler myocardial velocities. It has been suggested that Left atrial (LA) strain as measured by 2D speckle tracking can be used to evaluate dynamic LA function.

Objective: To study the relation between left atrial deformation and the severity of coronary artery stenosis in patients with stable coronary artery disease (CAD).
