Corrected QT Interval Prolongations in Patients with non–ST-Elevation Acute Coronary Syndrome

[Corrected QT interval prolongation: a new predictor of cardiovascular risk in patients with non-ST-elevation acute coronary syndrome].

INTRODUCTION AND OBJECTIVES Recently we reported that prolongation of the corrected QT (CTc) interval is an independent risk factor in patients with unstable angina and acute ischemic changes. The aim of this study was to determine the prognostic value of this variable in patients with non-ST-segment elevation acute coronary syndrome who do not exhibit acute ischemic changes on admission ECG. ...

Prognostic Value of Corrected QT Interval and its Correlation with Cardiac Troponin T in Non-ST-Elevation Acute Coronary Syndrome

[Corrected QT interval and corrected QT interval dispersion is worthwhile when interpreted with other repolarization measurements].

We read the article entitled ‘‘The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor’’ by Ceker et al. with interest.1 The authors investigated the effects of esmolol on the hemodynamic, correctedQT (QTc) interval and corrected-QT interval dispersion (QT...

Vitamin D deficiency predicts the ST elevation type of myocardial infarction in patients with acute coronary syndrome.

According to studies, a significant association exists between the low levels of vitamin D and cardiovascular diseases such as myocardial infarction (MI). In a prospective, case control study, 88 patients with acute coronary syndrome (ACS) including ST elevation myocardial infarction (STEMI) and Non-STEMI were enrolled. The plasma level of 25-hydroxy vitamin D[25(OH)D] was obtained at the time ...
