The impact of plasma glucose levels on in-hospital and long-term mortality in non-diabetic patients with ST-segment elevation myocardial infarction patients Open
Objective: Increased admission plasma glucose can be seen in the acute phase of acute coronary syndromes (ACS). Hence, we performed a retrospective study to evaluate the admission plasma glucose concentration in patients with ST-segment el…
View article: Usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation
Usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation Open
Background: Right ventricular stroke work index is a useful but invasively measured parameter that can be used to predict right heart failure following continuous-flow left ventricular assist device implantation. Right ventricular contract…

Resistant Ventricular Tachycardia due to Idiopathic Left Ventricular Aneurysm: Successful Treatment with Surgery Open
Left ventricular aneurysms (LVAs) are characterized by a wide connection to the left ventricle and paradoxical systolic motions. Although patients with LVAs are usually asymptomatic, some may present with arrhythmias, heart failure, and ev…

The established electrocardiographic classification of anterior wall myocardial infarction misguides clinicians in terms of infarct location, extent and prognosis Open
Background The currently used scheme for the classification of infarct location and extent in anterior myocardial infarction (MI) is intuitive rather than being evidence‐based, and recent evidence suggests that it may be misleading both in…

A Rare Cause of Angina After Coronary Bypass Grafting; Left İnternal Mammary Artery to Pulmonary Artery Fistula and Successful Treatment with Transcatheter Coil Embolization Open
Fistula from left internal mammary artery (LIMA) to pulmonary artery (PA) is rarely encountered in daily practice. In recent years, endovascular therapy options have emerged for the treatment of fistula formations and replaced with surgery…

A tale of two formulas: Differentiation of subtle anterior <span>MI</span> from benign <span>ST</span> segment elevation Open
Background It may sometimes be difficult to differentiate subtle ST ‐segment elevation ( STE ) due to anterior myocardial infarction ( MI ) from benign variant ( BV ) STE . Recently, two related formulas were proposed for this purpose. How…
