title: Relation between QT duration and mortality in an elderly Japanese population.
abstract: The effects of prolonged QTc intervals on mortality were investigated in about 3,500 elderly Japanese patients followed for approximately 8.8 years. Prolonged QTc was found to be a marker for risk for all-cause mortality and mortality from heart disease or from coronary heart disease (CHD) after adjusting for other CHD risk factors. Even in Japanese subjects, who have a lower coronary heart disease rate than that of Caucasians, the careful observation of subjects with a prolonged QTc is believed to be necessary.
