QT dispersion correlates with systolic rather than diastolic parameters in patients receiving anthracycline treatment.

Objective: The aim of this study was to investigate the relation of QT dispersion to left ventricular (LV) systolic and diastolic function in patients undergoing anthracycline therapy.

Methods: We used echocardiography to evaluate LV systolic and diastolic function and electrocardiography to evaluate QT dispersion and corrected QT dispersion (QTcD) in patients with hematological diseases, who received anthracycline therapy.

Patients: Seventy-two patients with hematological diseases who were receiving anthracycline treatment were enrolled in the present study.

Blunt circulatory response to exercise in coronary high-risk subjects among apparently healthy Japanese.

Background: Endothelial dysfunction leads to atherosclerosis and the hypothesis of the present study was that the systemic circulatory response during exercise would be a manifestation of endothelial dysfunction.

Methods And Results: The circulatory response to exercise of 1,214 apparently healthy people (946 men, mean age 51.2 +/- 10.

Higher C-reactive protein concentration and white blood cell count in subjects with more coronary risk factors and/or lower physical fitness among apparently healthy Japanese.

Of 2,722 people (1.876 men, mean age: 51.3+/-10.
