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.

A very rare interarterial communication: total occlusion of right coronary artery with antegrade collateral supply from left circumflex artery through conus branch.

Purpose: The purpose of the present case report is to describe an extremely rare and unusual coronary interarterial communication.

Methods: A 65-year-old female patient admitted with acute coronary syndrome underwent a coronary angiography performed with Judkins technique to obtain standard angiographic views.

Results: We have demonstrated a very rare interarterial communication traversing an unusual retroaortic path between the body of left circumflex artery and the conus branch of the right coronary artery.

The Effect of Lower and Higher Calorie Meal on the Parameters of Ventricular Repolarization in Healthy Subjects.

Background: Cardiovascular modulation following meal consumption has been known. Little and conflicting data is present regarding electrocardiographic QT and QTc intervals after a meal, and status of ventricular repolarization following meal is not known comprehensively.

Aim: To inquire the electrocardiographic status of ventricular repolarisation thoroughly after lower and higher calorie meal consumption in a comparative manner.
